Key Points

  • The sales revenue in the FY December 2021 was 559 million yen, up 105 million yen from the previous term. It is mainly composed of sales of Sancuso® (SP-01) and episil® (SP-03). Due to the spread of the novel coronavirus, various promotional activities such as the company group and sales partners' MRs' (medical representatives) access to medical sites have been restricted, which have affected the prescription and shipping quantity of both products. The revenue plan from the licensing-out contract of darinaparsin (SP-02) and arfolitixorin (SP-05) at the beginning of the term is not achieved. R&D expenses decreased 1,083 million yen year on year to 845 million yen. The costs were mainly attributable to application costs and manufacturing and development costs for darinaparsin (SP-02) and clinical development investment for phase III clinical trial (final clinical trial) for arfolitixorin (SP-05). SG&A expenses dropped 484 million yen year on year to 1,948 million yen. The SG&A expenses included marketing activity expenses such as costs for post-marketing surveys and system operating expenses for the Chinese independent sales system, etc. As a result, operating loss decreased 1,697 million yen year on year to 2,419 million yen.


  • The forecasts for the FY December 2022 indicate ranges. Sales revenue is expected to be around 2.3 to 3.8 billion yen, and operating profit is forecasted to range from a loss of 1.1 billion yen to a profit of 150 million yen. The company's revenue is expected to include the sales revenue of Sancuso® (SP-01) and episil® (SP-03), the sales revenue of darinaparsin (SP-02) and the revenue from the overseas licensing-out contracts, and the income from licensing out arfolitixorin (SP-05) in Japan.


  • Regarding darinaparsin (SP-02), we would like to continue to wait for its release, which would take place through the authorities' approval, during this term. In addition, arfolitixorin (SP-05) is a drug for colorectal cancer, with about 150,000 patients (affected) in Japan. Thus, its marketability is extremely large. We would like to continue to pay attention to the plan's progress, which entails announcing the top-line results of its phase III clinical trial in the first half of 2022 and applying for approval to the authorities in the second half of the same year.


  • The year 2022 will see a big step for the company as it is licensing out the rights for darinaparsin (SP-02) and arfolitixorin (SP-05) and expecting product sales revenue from darinaparsin (SP-02), a third product following Sancuso® (SP-01), episil® (SP-03). Up until now, the company has set a numerical target of achieving profitability in operating profit, excluding R&D expenses. However, we would like to pay attention to the company, which is finally entering the stage where pure operating profit can be expected in this term.


1. Company Overview

As a specialty pharma* specializing in oncology, Solasia Pharma develops and sells medicines for cancer treatment and supportive care, etc. in Asia, mainly Japan and China, each of which has a promising market.
Its significant strengths and features are the development staff with abundant practical experience led by CEO Arai, high rate of successful development, the stable business foundation, feasibility of business model, and so on.
*Specialty Pharm A new drug developing enterprise possessing research and development capabilities which has a certain standard in its field of expertise, both domestically and internationally.


1-1 Corporate History

Its predecessor is Japan Bridge Inc., which was established as a foothold for preparing for the business of developing pharmaceutical products in the U.S. in December 2006 jointly by ITOCHU Corporation and MPM Capital, a U.S. venture capital specializing in bio business.


In May 2008, the company introduced the exclusive right to develop and sell the first product “Sancuso® (SP-01)” in Japan, Taiwan, Singapore, Malaysia, and China, including Hong Kong and Macau.
In September 2008, the company was renamed Solasia Pharma K.K.
Then, the company introduced the exclusive right to develop and sell “darinaparsin (SP-02)” in the Asia-Pacific region (March 2011), introduced the exclusive right to develop and sell it around the world, including the U.S. and Europe (July 2014), and introduced the exclusive right to develop and sell “episil® (SP-03)” in Japan and China (March 2015), to enrich pipelines. The company also provided Kyowa Kirin Co., Ltd. with the exclusive license to develop and sell “Sancuso® (SP-01)” in Taiwan, Hong Kong, and so on. (February 2010), and provided Lee's Pharmaceutical (HK) Limited with the exclusive license to sell “Sancuso® (SP-01)” in China (excluding Beijing, Shanghai, Guangzhou, Hong Kong, and Macau). All these paved the way for monetization.


In 2016, the company applied for the approval for manufacturing and sales of medical apparatus for “episil® (SP-03)” in China and Japan, and provided Meiji Seika Pharma Co., Ltd. with the exclusive distributorship in Japan and provided Lee’s Pharmaceutical (HK) Limited with the exclusive distributorship in China (excluding Beijing, Shanghai, and Guangzhou).


As the company was expected to grow as a pharmaceutical company specializing in cancer, it was listed in Mothers of Tokyo Stock Exchange in March 2017.


In November 2017, the company acquired the exclusive right to develop and sell for "PledOx® (SP-04)" in Japan, China, South Korea, Taiwan, Hong Kong, and Macau. In August 2020, it also introduced exclusive right to develop and sell for "arfolitixorin (SP-05)" in Japan, and currently has five pipeline products.


In May 2018, “episil® (SP-03)” was released in Japan, as the first product released by the company. In 2019, the company released “Sancuso® (SP-01)” and “episil® (SP-03)” in China, and “episil® (SP-03)” in 2020 in South Korea. Namely, the company is making a transition from the “development” stage to the “sales and commercialization” stage.


1-2 Corporate Philosophy・Management Philosophy

The company’s name, SOLASIA, is a coined word combining Sol (the Sun in Latin) and Asia (Asian counties). It represents the company’s mission which is to be the Sun brightening the future of various people facing many challenges of cancer in Japan and other Asian countries.
The management philosophy adopts the following mission, vision, and values.


Role to Fulfill (Mission)

*Better medicine for a brighter tomorrow

Ideal Situation (Vision)

*To be recognized domestically and overseas and gain a high level of trust from all stakeholders.

*To be recognized as a specialty pharma developing innovative medicine, where each employee possesses passion, ambition, and a sense of morality, strives to better themselves, maintains a high level of expertise, and continuously endeavors for new value and creation for the future.

*To meet the needs of people (medical practitioners and patients) who need our products and contribute to them.

Shared Values (Value)

*Create value for patients.

*Have high ethical standards.

*Trust and respect each other.

*Work as a team.



In addition, the following two points are listed as management policy.

① For the time being, we will continue the in-licensing of new products in cancer and rare disease field where major pharmaceutical companies do not emphasize from a performance-based approach and contribute to patients without adequate medication.

② Through the commercialization of products, we will promptly establish the financial stability needed to realize our management philosophy, and secure independence.



The company will focus on developing new drugs to solve unmet medical needs (medical needs for diseases for which no treatment has been developed), which is a niche market but has many troubled patients. As research and development is proceeding, they will have to rely on financing CF now, but they plan to make operating CF positive soon and build a strong basis to achieve continuous growth.


1-3 Environment Surrounding Solasia Pharma

According to “Vital Statistics, 2020” published by the Ministry of Health, Labour and Welfare, in 2020, the leading cause of death was malignant neoplasm (cancer), 307.0 per 100,000 people. In 1981, cancer overtook cerebrovascular diseases, the former number one cause of death, with the mortality rates from cancer being 142.0 and that from cerebrovascular diseases being 134.3. Since then, cancer has been the leading cause of death for the 30 consecutive years and keeps going up every year.
As it is said that the incidence rate of cancer is rising due to aging and changes in lifestyles including diet, the number of patients and deaths regarding cancer is rising in China as well.

Amid such situation, the sales of the world’s pharmaceutical market in 2019 were 1,262.4 billion US dollars (approximately 137 trillion yen). The U.S. has the largest pharmaceutical market, followed by China, which overtook Japan in 2013, and Japan, which has the third largest market.
In the future, it is said that the market in China will expand to the point where it will share the top position with the U.S.
The total market size of China, the second biggest country, and Japan, the third biggest country, is 229.8 billion dollars (about 25 trillion yen). For the time being, this huge market will be the company’s main target.

In addition, the anticancer drug market in China is over 3 trillion yen, accounting for more than 10% of the total pharmaceutical market, and it has grown at a CAGR of approximately 14% over the past five years.

(Source: Solasia Pharma)


As the mortality rates from cancer increases as shown above, expectations for “new anticancer drug” and “cancer supportive care” are growing all over the world.


(New anti-cancer drug)
In cancer treatment provided using anticancer drug, it is said that a majority of hospitals use the polytherapy which uses multiple anticancer more than the monotherapy which uses a single anticancer drug.
In addition, although it depends on cancer types, there is significant risk of relapses. Besides, in case of intractable cancers, it is difficult to cure such cancers only with a single treatment method, which means that a single medicine is not always an absolute cure, and therefore, other therapeutic medications will hardly be direct “competing products.” Molecular targeted drugs and immunotherapy have also attracted attention in recent years, however chemotherapeutic agents still hold an important position for treatment of many cancer types. Standard therapy involves a regimen containing a cytotoxic anticancer drug, for which a high medical demand is expected in the future as well.


(Cancer supportive care)
Anticancer drugs are potent medicine that attacks cancer cells, and side effects are inevitable.
If the side effects on patients cannot be controlled, anticancer therapy through drug administration must be stopped, which has a risk of resulting in cancer progression.
As a result, expectations for drugs and medical devices which control such side effects are increasing in order to avoid treatment discontinuation and complete cancer treatment. In addition, while therapeutic drugs for cancer must be approved for each cancer type, supportive care can be provided to a wide range of patients regardless of cancer types, which means that there will be strong needs and markets.


In summary, needs for cancer treatment in Japan and China are growing and there are great expectations for new anticancer drugs and cancer supportive care. Solasia Pharma is establishing business model and business strategy to incorporate such needs and boost earnings.


1-4 Business Description

(1) Business Model
Before the launch of new medicines, it is usual to go through the processes spanning from “basic research” to “pharmaceutical research,” “nonclinical development (trials conducted using animals to examine medicinal and pharmacological action, in-vivo pharmacokinetic properties, adverse effects, etc.),” and “clinical development (scientific trials carried out to examine the effects of pharmaceuticals and treatment techniques on human beings), obtain approval from the authorities, and then conduct “manufacture” and “sales, marketing, and post-marketing surveillance.”
Although major pharmaceutical companies are propelling outsourcing to CROs at the stage of clinical development to make considerable amounts of research and development costs variable, they basically perform all of the above-mentioned processes internally.
Such a system has supported high profitability of pharmaceutical companies. The life science field, however, is currently advancing and becoming complicated and diverse at a rapid rate, and there is an increasing possibility that each company’s unique drug discovery technology quickly becomes obsolete.
In addition, there are a myriad of cases where practical application of new drugs is given up before clinical development, regardless of costs and time spent from the stage of basic research, and therefore new drug is not established in the end. In other words, pharmaceutical development is facing high risks at all times.


Accordingly, Solasia Pharma does not conduct the processes from basic research to nonclinical development on its own which has high failure rate. By in-licensing promising pharmaceuticals that are still under development from outside companies, it embarks on development starting from clinical development. It utilizes its strength and reduces risk by focusing management resources on the business activities subsequent to the development stage. At the moment, it plans not to do manufacturing due to the large cost burden.


Regarding the sales and marketing structure, the company has set up a system that takes into account the balance between high profitability and risk control.
In general, pharmaceutical companies hold gross profit margins to high standards, which is considered to be attained by their in-house manufacture and sales activities.

On the other hand, coverage of sales territories (e.g., to cover all over Japan) is required for pharmaceuticals, and therefore, a rise in fixed costs is inevitable for establishing a company’s own sales network. Accordingly, Solasia Pharma uses both “self-selling model” and “licensing-out model” (sales rights are granted to other companies for pharmaceuticals that have completed clinical development).


(Source: Solasia Pharma)


(Self-selling model)
The current major licensing-out partners are the following four companies.

Meiji Seika Pharma Co., Ltd.

*A pharmaceutical company of the Meiji Group. It is a specialty pharma in the fields of cancer, infections, and the central nervous system and has yielded sales results of multifarious products in the cancer field.

*Japanese partner with the rights of “episil® (SP-03)”

Nippon Kayaku Co., Ltd.

*Founded in 1916. The company specializes in cancer-related products in the pharmaceutical business, handles everything from new drugs to biosimilars and generics, and provides medical institutions with highly reliable information necessary for anticancer drugs.

*Japanese partner with the rights of darinaparsin (SP-02)

Lee’s Pharmaceutical (HK) Limited

*A Chinese pharmaceutical company listed on the Hong Kong market. It sells multiple pharmaceutical products in fields including the cancer field across China through about 30 bases.

*Chinese partner with the rights of “Sancuso® (SP-01)” (excluding Beijing, Shanghai, and Guangzhou)

*Chinese partner with the rights of “episil® (SP-03)” (excluding Beijing, Shanghai, and Guangzhou)

Maruho Co., Ltd.

*A pharmaceutical company that was founded in 1915 and engages in the research, development, production, and sale of pharmaceutical products, etc. It is especially excellent in the dermatological field.


Solasia Pharma plans to create licensing-out partnerships with a focus on mid-sized pharmaceutical companies which it can fall in line easily and forge win-win relationships.


(2) Marketing structure in China
The company, which is aiming to develop a huge Chinese pharmaceutical market, will build a self-selling structure and carry out the self-selling business model with an aim of maximizing product sales profit and managing fixed costs in three major cities in China, “Beijing, Shanghai, and Guangzhou.”
Self-selling activities in China are handled by Solasia Medical Information Consulting (Shanghai) Co. Ltd., which is a wholly owned subsidiary of Solasia Pharma.


Although the total population of the 3 cities accounts for only about 5% of the entire population of China, a number of large hospitals with advanced medicine which uses anticancer drugs are located in the above 3 cities, making them huge markets which account for 30% of the Chinese anticancer drug market.
Furthermore, whether new pharmaceuticals are used and popularized depends highly on judgment and decision made by influential doctors, and thus, it is extremely important to make sales activities targeting large hospitals where such influential doctors work.
In addition, such self-selling activities will be done not in a large scale throughout China but in a small scale in each of the 3 cities, which makes it possible to cover with a relatively small number of staff.


Point 1: Experienced management team
The marketing and sales departments of the company’s wholly owned subsidiary Solasia Medical Information Consulting (Shanghai) Co. Ltd., which was established in 2014 and engages in company’s own marketing in China, are led by the following 4 people in charge.



(Source: Solasia Pharma)





General Manager

Vivian Zhang

Former Roche, Director of Oncology Business Unit, etc., Physician (former Shanghai Ninth People’s Hospital)

Marketing Director

Jingjing Lu

Former MSD, etc

Sales Director

Jimmy Guo

Former Roche, BI, etc. Physician (former Suzhou City Hospital, Cardiac Surgeon)

Medical and Regulatory Affairs Director

Li Zhou

Former Sanofi, MSD


(As of June 2021)


Dr. Vivian Zhang, the president of the subsidiary, worked at a university hospital for 4 years as a clinician, and then worked at a pharmaceutical company for 26 years, gaining a wealth of experience mainly in the oncology field. Above all, at Roche, a global pharmaceutical company, she achieved excellent sales results with well-known, powerful anticancer drugs that are leaving their names on the history of anticancer drugs such as Herceptin (antineoplastic drug), Tarceva (antineoplastic drug), and Avastin (antineoplastic drug) as well as antiemetics Kytril (granisetron hydrochloride) that prevents side effects in anticancer drug treatment. She was in charge of the anticancer drug business.
Ms. Jingjing Lu, Dr. Jimmy Guo, and Mr. Li Zhou are also from Mega Pharma and have extensive experience.


Under these experts, a total of approximately 40 MRs are employed in Shanghai, Beijing, and Guangzhou. 70% of them are from major foreign-affiliated pharmaceutical companies and have an average of more than two years of sales experience in the cancer field.
The company operates a strong marketing and sales force under an experienced management team.


Point 2: Highly regarded by Chinese medical community
The judgement and decision of influential physicians greatly affect the outcome of the use and distribution of new medicines, and China is no exception.
Under these circumstances, “Sancuso® (SP-01)” is already recommended as one of the standard treatments for nausea and vomiting in the Chinese version of the NCCN guidelines for cancer treatment, which is referenced in the clinical sites.
In addition, at Chinese Society of Clinical Oncology (CSCO), prominent clinicians who are leading the field of cancer treatment in China highly valued “Sancuso® (SP-01)” for its feature of easily suppressing nausea and vomiting in the entire chemotherapy process. In response to this, “Sancuso® (SP-01)” is listed as a standard antiemetic treatment option for cancer treatment in the first guideline for proper use of antiemetics issued by CSCO.


The company is receiving such a high rating because of the superior efficacy of “Sancuso® (SP-01)”. But it is obvious that the strong relationship with the Chinese clinical network that the management team had been building since their times with Roche is also playing a key role, and it is a major advantage of the company that other bio-ventures do not have.


Point 3: Current status and the future of marketing activities
The company has completed establishing the self-selling system for “Sancuso® (SP-01)” and “episil® (SP-03)” by placing bases in 3 cities and employing a total of 40 MRs.
In these cities, the company covers over 70 large hospitals where influential physicians work and promote sales expansion by diffusing information.


First, it is necessary to open an account in each hospital or hospital pharmacy, and general pharmacy. So far, accounts have been opened in about half of these targets. Both products have not yet been covered by NRDL (China's National Reimbursement Drug List), so the rise in sales amount is still slow, but the company is expecting to accelerate the speed as more accounts are opened in the future.


It has been several years since the company launched Sancuso® (SP-01) and episil® (SP-03), but both of those have been listed in the clinical practice guidelines in China and have been adopted by core hospitals. Due to such factors, sales volume increased significantly in the previous term and this term. The marketing activities conducted so far have begun to bear fruit, despite the impact of the novel coronavirus crisis.


“Sancuso® (SP-01)” and “episil® (SP-03)” in other Chinese regions will be sold by Lee’s Pharma, the sales contract partner.

(3) Products/Development Pipeline
Solasia Pharma currently owns the following 5 products/development pipelines in accordance with the above-mentioned management policy. (As of February 15, 2022)
In addition to SP-05 introduced in 2020, the company is striving to enrich pipelines. The target area is basically the cancer-related one, but the company will enhance the research function by the collaborative research with the alliance partners: EditForce and GeneCare Research Institute, in addition to the introduction from the outside, and aim to expand the target area.




*Development candidate 1

EditForce: Using the PPR (penetratricopeptide repeat) protein platform technology, which is the EditForce platform technology, multiple projects (target disease, target gene sequence, mechanism of action) , which is based on RNA editing, are being promoted in the oncology field.

*Development candidate 1

GeneCare Research Institute: Promoting the development of a new treatment method using the nucleic acid medicine RECQL1-siRNA for the treatment of peritoneal metastasis (peritoneal dissemination) and associated ascites accumulation of various gastrointestinal and ovarian cancers, etc.

1) “SP-01: Transdermal Delivery System Sancuso®” (Sales name in Chin 善可舒®)




Chemotherapy Induced Nausea and Vomiting (CINV)

Characteristics/Strength compared with competitive drugs

*The world’s only transdermal patch type 5-HT3 receptor antagonist

*The effect per administration (patch) lasts for 5 days, which covers the administration period of the general chemotherapy regimen (provided for 1 - 5 days). It can also be used for outpatients.

*In June 2019 (3 months after its launch), it was listed as a standard antiemetic treatment option for cancer treatment in the first guideline for proper use of antiemetics issued by CSCO.


(※)CSCO(Chinese Society of Clinical Oncology) : The most prominent and largest academic conference related to cancer in China


Overview of indications
Nausea and vomiting are widely known as typical side effects caused by anticancer drug.
Administration of anticancer drug damage cells called Chromaffin cells in the small intestine.
The damaged Chromaffin cells produce serotonin, a neurotransmitter, which is taken in by the 5-HT3 receptors in the peripheral vagus nerve. This stimulus is transmitted through the peripheral vagus nerve to the medulla oblongata via the chemoreceptor trigger zone (CTZ) in the area postrema of the fourth ventricle of the brain, stimulating the vomiting center which gives living organisms commands to develop nausea and vomiting, and then symptoms of nausea and vomiting appear.
It is necessary to disrupt the stimuli generated by serotonin to the 5-HT3 receptors in order to control nausea and vomiting. There are a variety of “5-HT3 receptor antagonists” which are drugs used for the above purpose, and one of the representative agent is Granisetron.


Overview of “Sancuso® (SP-01)”
“Sancuso® (SP-01)” is a transdermal 5-HT3 receptor antagonist containing Granisetron and is the world’s only patch-type antagonist.





*Chinese package of Sancuso®

Anticancer drugs are administered over 5 days in most cases, but injections and oral antiemetic agents are effective only for about 1 to 2 days and must be injected multiple times within the anticancer drug administration period. On the other hand, “Sancuso® (SP-01)” maintains the concentration level of Granisetron in blood on a stable basis for 5 days. Therefore, once a patch of “Sancuso® (SP-01)” is attached, there is no need to add antiemetics, which enables cancer treatment not through hospitalization but through outpatient care and contributes significantly to the improvement of patients’ quality of life.


Another advantage is that transdermal type drugs can be administered even to patients who are facing difficulty in taking oral medicines due to various symptoms including nausea, vomiting, and stomatitis. Earning reputation for the above-mentioned advantages, “Sancuso® (SP-01)” is recommended for prescription in the American NCCN clinical practice guidelines and the Chinese clinical practice guidelines.


Current situation of development and commercialization
Currently, it has been released (distributed by other companies) in more than 20 countries and regions such as the U.S., Europe, and South Korea, etc. Solasia Pharma is planning potential extension of indication of “Sancuso® (SP-01)” from current CINV (Chemotherapy Induced Nausea and Vomiting) to RINV (Radiotherapy Induced Nausea and Vomiting).


In China, the company finalized their application for approval in June 2014, and obtained approval in July 2018, along with permission to import drug license. It received milestone payments in the third quarter of FY December 2018, and the sales revenue was recorded.
Thereafter, the manufacturing process for commercial products was established, and manufacturing the products for the first shipment completed. In November 2018, the company began shipping the products to the direct sales destination, ITOCHU Corporation, with which the company entered into a dealership contract for the Chinese market.
Then, the Chinese customs clearance procedures also completed, and sales began as planned in March 2019.
The company conducts sales activities through a self-selling structure in Beijing, Shanghai and Guangzhou, and through Lee’s Pharma, which is the licensed distributor, in other regions of China.


Evaluation comments from major Chinese clinicians
On March 16, 2019, the company held (co-sponsored) the “ Sancuso® China national launching meeting” in Shanghai.
The chairman of Chinese Society of Clinical Oncology (CSCO), Professor Li Jin, and the vice chairman, Professor Qin Shukui and Professor Ma Jun were chairmen of the meeting, a total of approximately 200 oncologists from all over China attended the meeting. At that meeting, Chinese key opinion leaders made remarks on “SP-01: Sancuso®” as follows.


Professor Qin Shukui (Vice Chairman of CSCO)
“Without any anti-emetic measures, 70%-80% of chemotherapy patients would experience CINV which would severely affect their quality of life. Often, patients will have to be treated with reduced dosage or even withdrawn from chemotherapy, with negative impacts on the treatment outcomes. The traditional CINV prevention methods are mainly short-term intravenous injection, which due to great fluctuation in blood concentration, requires repeated administration which is inconvenient for patients. With unique transdermal system, Sancuso® gradually releases granisetron into blood every day for up to 7 days. With one patch per one chemotherapy cycle, it is a new non-invasive treatment choice for chemotherapy patients.”
Professor Ma Jun (Vice Chairman of CSCO)
“The emetic risk in patients receiving HEC and MEC chemotherapy will continue for 2-3 days after last dose of chemotherapy. For multi-day chemotherapy, there is an overlap between acute and delayed vomiting, which requires more stable and long-lasting drug. Sancuso® covers different emetic stages including expected, acute and delayed nausea and vomiting. The 7 days stable efficacy makes the whole process CINV management possible and allows patients to feel at ease throughout the entire chemotherapy cycle.”


Professor Li Jin (Chairman of CSCO)
“The successful launching of Sancuso provides a long-lasting, stable and non-invasive new choice for the prevention of nausea and vomiting in Chinese chemotherapy patients. As a new choice for the prevention and treatment of chemotherapy related vomiting, with one patch, which is simple and easy, it makes CINV whole process management more convenient, it helps to standardize clinical treatment of CINV and further improves the treatment rate of CINV.”


CSCO’s first guideline for proper use of antiemetics was issued.
In June 2019, three months after Sancuso® (SP-01) was launched, CSCO issued the first guideline for proper use of antiemetics, and it was listed as a standard antiemetic treatment option for cancer treatment.
Prof. Qin Shukui, deputy director of CSCO and Guideline team leader, said, “This guideline recommends Sancuso® for an antiemetic treatment against highly and moderately emetogenic chemotherapy, providing a non-invasive and tolerable treatment option to cancer patients.”


The company plans to grow 6% on the basis of quantity and aims to increase share in China’s 5-HT3 RA antiemetic market, which is said to be 80 billion yen or more, through upper and lower streams of sales activities, including gaining recognition from the leading clinicians called Key Opinion Leaders on the characteristics of “Sancuso® (SP-01)” and its advantage over competitors and providing the information to clinicians.


2) “SP-02novel chemotherapeutic agent darinaparsin”




Relapsed or Refractory Peripheral T-cell Lymphoma (PTCL)

Characteristics/Strength compared with competitive drugs

*There are no approved drugs for PTCL indication in Europe (Other drugs are on the market in Japan and America).

*Compared to the drugs approved in Japan and America, no severe side effect (myelosuppression, stomatitis) has been reported, which means that “SP-02” is highly safe and can be expected for a longer period of time of administration or co-administration.


(Overview of indications)
Malignant lymphoma is one type of hematologic cancer where lymphocytes in white blood cells become cancerous.
The types of lymphocytes include B cells, T cells, and NK cells, and when these cells become cancerous and continues uncontrolled growth, malignant lymphoma develops.
Peripheral T-cell lymphoma (PTCL) is one kind of malignant lymphoma which arises from T cells in lymphocytes and is categorized into the “intermediate-grade lymphoma” where the disease progresses monthly, and it is said to account for 10-15% of the intermediate-grade lymphoma. The five-year survival rate from malignant lymphoma is lower than that from B-cell lymphoma, with the ratio being around 25%.
Estimated number of PTCL patients (Japan): Approximately 4,000/year*


(Current situation of development and commercialization)
The development of “ darinaparsin (SP-02)” started aiming for recurring/intractable peripheral T-cell lymphoma (PTCL) indication as mentioned above.


The early second phase clinical trials in the U.S. were completed in April, 2012 and have shown certain efficacy in Caucasians.
In the first phase clinical trial completed in April 2015 in Japan and Korea, safety and tolerability of the drug were confirmed, with certain efficacy in Asians suggested.
In addition, the international phase II study, which was started in Japan, South Korea, Taiwan, and Hong Kong in was completed in September 2019.


As originally planned, the trial results were announced in June 2020 following statistical analysis. In addition to meeting the requirements for the primary endpoint which is antitumor effect, no safety concerns were noted regarding secondary endpoints either. As positive results were achieved, the company applied for the approval for manufacturing and sales in Japan in June 2021 for the first time in the world. It is expected to be approved by the authorities in the first half of 2022 and to be released in the second half of the same year.


The company is planning to apply for approval in South Korea, Taiwan, and Hong Kong following the conclusion of a contract for offering the sales rights.


In China, phase II and III clinical trials, which are the final trials, as well as the licensing-out of the rights are under consideration. The phase II clinical trial was completed in the U.S. In Europe, preclinical trials have been completed, and the company is preparing for phase II and III clinical trials and is negotiating for licensing out the rights in each region. However, the licensing-out agreements are expected to be concluded after the drug is approved in Japan.


Solasia Pharma holds an exclusive worldwide license to develop and commercialize. For the Japanese market, Solasia has already derived an exclusive right to develop and sell to Nippon Kayaku Co., Ltd., and for Republic of Colombia, Peru, Ecuador, Venezuela, Chile, Panama, Costa Rica, and Guatemala, an exclusive right to sell etc. to the Colombian company HB Human BioScience SAS.


It is known that malignant lymphoma often relapses. Accordingly, Solasia Pharma believes that multiple medicines with different mechanisms of action are necessary and the market scale is significant.
In addition, the company is aiming to extend indication of “SP-02” not only to peripheral T-cell lymphoma but also to other hematologic cancers (ATLL (Adult T cell Leukemia / lymphoma), AML (Acute Myeloid Leukemia)) and solid carcinoma and currently, non-clinical trials are being conducted in parallel.
At the 79th Annual Meeting of the Japanese Cancer Association held in October 2020, the possibility that it will become a medicine against adult T-cell leukemia lymphoma (ATL) was suggested.
Future growth is expected as it is currently the only anticancer drug whose development has been completed among the pipelines of the company, which engages primarily in the development of anticancer drugs and cancer supportive care (drugs supporting cancer treatment, etc.).


3) “SP-03episil® oral liquid”



Purpose of its use

Control and relief pain of oral mucositis caused by chemotherapy or radiotherapy – Medical Device

Characteristics/Strength compared with competitors

*As there is no standard treatment for stomatitis caused by chemotherapy and radiotherapy, how to relieve the symptom relies on symptomatic treatment by each hospital. There is strong demand for new treatment.

* “episil® (SP-03)” contains no pharmaceutical agent, so there is no side effect nor interaction with anticancer agents.


(Overview of indications)
In addition to nausea and vomiting due to anticancer agents, oral mucositis are also serious side effects caused by chemotherapy or radiotherapy.


Stomatitis can be divided into 2 types: the primary stomatitis, which is “stomatitis caused by chemotherapy directly affecting the oral mucosa” or “stomatitis resulted from local infection due to the salivary gland tissue disorder and deterioration of intraoral self-cleansing action because of impaired saliva secretion attributed to radiation exposure” and the secondary stomatitis, which is “attributed to intraoral infection due to myelosuppression resulting from a decline in the number of white blood cells.”
The incident rate of stomatitis developing during treatment using anticancer drugs is 30-40%, and that of stomatitis developing during anticancer drug treatment provided together with radiotherapy to the head and neck is nearly 100%.


Stomatitis occurs together with 300-500 inflammations arising in the course of chemotherapy or radiotherapy. The pain makes oral intake of food and water by patients difficult, which results in a decrease in physical strength. In case the symptom is severe, it will adversely affect or halt the progress of cancer treatment. Up until now, there is no established standard treatment therefore the majority of hospitals conducted palliative treatment.


(Overview of “episil® (SP-03)”)
“ Episil® (SP-03)” is a lipid-based liquid, which is dropped and applied on the oral mucosa, which the company has been developing under the category of medical device.


(Source: Solasia Pharma)


In a few minutes after application of a proper dose to the oral mucosa, the liquid absorbs the water in the oral cavity and transforms to a bioadhesive gel which mechanically protects the affected area. The effect of mitigating the pain of stomatitis has been clinically shown to last for about 8 hours.


(Current situation of development and commercialization)
Solasia Pharma submitted an application for approval in Japan in 2016 and obtained an approval of “episil® (SP-03)” as new medical device in Japan by the Ministry of Health, Labour and Welfare on July 6, 2017. In January 2018, “episil® (SP-03)” was approved at the 388th general meeting of the Central Social Insurance Medical Council for being covered by insurance, starting in April 2018. Following reimbursement listing, 7,660 yen per bottle(10ml) as of October in 2019, in May 2018, it was launched by Meiji Seika Pharma, which is the licensee who holds the exclusive sales rights of “episil® (SP-03)” in Japan.
In China, the company applied for approval in May 2016 and obtained the approval to import and sell medical equipment in February 2019. It began sales of the products in July 2019.
The company conducts sales activities in Beijing, Shanghai and Guangzhou, and through Lee’s Pharma, which is a licensed distributor, conducts sales activities in other regions of China.


In May 2021, episil® (SP-03) was included in the Expert Guidelines on the Diagnosis and Prevention of Acute Oral Mucositis Caused by Antineoplastic Therapy newly published by Chinese Society of Clinical Oncology (CSCO), and recommended as a new treatment option.
This Guideline is regarded as having “increased the attention of clinical oncologists to oral mucositis and standardized the treatment of oral mucositis in antitumor therapy, which is of great significance,” and as episil® (SP-03) was specifically featured, the company anticipates that this will give momentum to sales promotion in China.


Due to the product characteristics of “episil® (SP-03),” the company will “create a market” instead of entering into the existing market.
The market is estimated to be 20 to 30 billion yen in Japan and China, and the company is aiming to acquire a 30-50% market share.


In South Korea, the company concluded a contract for introducing the exclusive right to develop and sell the medical device in South Korea with Camurus AB, which is the licensing-out company, in August 2018, applied for approval to authorities in March 2019, and acquired the approval for import and sale of medical device in South Korea in October 2019. In January 2020, the company concluded a contract for exclusive dealership with Synex Consulting Ltd. as a sales partner in South Korea.
In September 2020, the sales started as initially planned.


4) “SP-04: Intracellular superoxide scavenger PledOx®”




Chemotherapy induced peripheral neuropathy (CIPN)

Characteristics/Strength compared with competitive drugs

*There is currently no approved drug to prevent or treat CIPN

*Superoxide dismutase mimetics to discompose and remove superoxide as one of reactive oxygen substance (ROS).



While steady progress in general was being made in development of the three preceding products, the company, which had been considering in-licensing the fourth pipeline since it became listed, sought for a new drug that satisfies the following three criteri “it is aimed for the oncology,” “certain progress has been made in clinical trials,” and “the company can gain the development right both in Japan and in China.” Then, in November 2017, the company was granted the exclusive rights to development and commercialization of “PledOx®,” a drug for treating CIPN, in Japan, China, South Korea, Taiwan, Hong Kong, and Macau by PledPharma AB (Currently Egetis Therapeutics AB, hereinafter referred to as “PledPharma”) of Sweden.


(Overview of indications)
Chemotherapy-induced side effects occur not only nausea and vomiting, and oral mucositis, but also peripheral neuropathy (CIPN). CIPN is known to manifest considerable symptoms such as dysesthesia in the hands, feet, the area around lips, etc., tightness in the pharynx and larynx accompanied by difficulty in breathing and dysphagia, numbness of the limbs, hypoesthesia, and sensory ataxia, caused by major chemotherapy drugs such as platinum-based drugs and taxanes.


If these side effects appear, by suspension of administering the drugs, some of the symptoms are alleviated in 80% of the cases and completely recovered in 6 to 8 months in 40% of the case; however, as discontinuation of administration of the drugs may mean suspension of cancer chemotherapy and change in the treatment policy, treatment of CIPN is one of the crucial medical issues. There is currently no approved drug to prevent or treat CIPN.
Estimated number of patients (Japan): Approximately 70,000-180,000/year*2 (taxane preparation administration)


(Overview of “PledOx® (SP-04)”)
PledPharma, the originator of “ PledOx® (SP-04)” is listed on Stockholm Stock Exchange and has strengths in development of pharmaceuticals against oxidative stress-related diseases. “PledOx®” (active ingredient name:calmangafodipir) is a new active ingredient created based on “Mangafodipir,” an MRI contrast medium, which had sold in the United States and Europe.


(Current situation of development and commercialization)
Development status
The global phase III clinical trial concerning peripheral neuropathy caused by the administration of Oxaliplatin, in which Japan, South Korea, Taiwan, and Hong Kong participated alongside U.S. and European countries, began in December 2018. However, a suspension of the trial was ordered by several authorities as French National Security Agency of Medicines and Health Products (ANSM) issued a clinical hold order in addition to FDA ordering a clinical hold of the POLAR-M study conducted by Pled in January 2020, etc.
Afterwards, Data Safety Monitoring Board performed a new safety evaluation and recommended the cessation of the registration of new study subjects and administration of the drug used in the clinical trial as multiple cases of severe allergic reactions and hypersensitivity were manifested after repeated administrations of Oxaliplatin and SP-04. As a result, Solasia Pharma and Pled made changes to the originally planned process, implemented “data cut off” — early closing of the case data collection — in the third quarter (July-September) of 2020, following which it decided to end the global phase III clinical trial.
Moreover, as Solasia Pharma recognizes that securing the safety of study subjects is the most important regarding conducting clinical trials, it declared its policy to formulate the plan concerning PledOx® (SP-04) after performing a detailed and solid evaluation of mainly information obtained after the end of the trial regarding safety and effectiveness.


Then, on December 2020, the flash report on the global phase III clinical trial was announced.
The major evaluation items regarding efficacy were not achieved. The frequency and details of adverse effects were almost consistent with the expected ones attributable to colorectal cancer, which is the target of chemotherapy and this trial.


Since the results of this trials are limited to the data on major evaluation items, Solasia Pharma K.K. and Pled Pharma AB will evaluate the details of trials results regarding secondary evaluation items, etc. and discuss the strategy for developing PledOx® (SP-04).
Amid such situation, Solasia Pharma has withheld the development concerning Oxaliplatin, which is a platinum-based drug, and is conducting additional animal experiments to explore the possibilities of development aimed at peripheral neuropathy brought about by taxanes.


Licensing-out plan
Solasia Pharma plans to give licenses in Japan and other Asian countries. In Japan, it concluded a contract for exclusive distributorship of “PledOx® (SP-04)” in Japan with Maruho Co., Ltd. (Osaka-shi, Osaka) in December 2019.
The economic conditions specified by the contract are (1) Maruho shall pay a lump-sum amount of 1 billion yen to Solasia Pharma, (2) Maruho shall pay up to 18.0 billion yen as milestone payments to Solasia Pharma according to the progress of development and sale, and (3) Solasia Pharma shall exclusively sell PledOx® (SP-04) to Maruho.


5) “SP-05arfolitixorin”




Increase in antitumor efficacy of the anticancer drug "fluorouracil" (for various cancer treatments, especially for colorectal cancer)

Characteristics/Strength compared with competitive drugs

*Phase I/IIa studies suggested enhanced antitumor effect compared to the standard chemotherapy treatment regimen for colorectal cancer.

*Based on the results of the ongoing Phase III study, the company aims arfolitixorin to be added for the colorectal cancer chemotherapy regimen as a "new standard treatment."


In August 2020, as a new pipeline, the company has signed an exclusive in-license agreement with Isofol Medical AB (Sweden) to develop and commercialize arfolitixorin (Solasia Pharma development product code: SP-05, generic name: arfolitixorin) in Japan.
It is estimated that the company will pay a total of up to 10.4 billion yen to Isofol as a payment that includes an upfront payment and milestones according to the development progress and sales achievement after successful development and development investment. Additionally, the company will pay royalties to Isofol according to the proceeds after the starting of sales.


(Overview of "arfolitixorin (SP-05)")
The existing anticancer drug "fluorouracil (5-FU)" is used for various cancer treatments, especially for colorectal cancer. It kills tumor cells by inhibiting DNA synthesis through depleting the chemical substance thymidine necessary for DNA synthesis.
As a standard therapy for colorectal cancer (colon and rectal cancers), "fluorouracil" is often used in combination with the folic acid preparation "levofolinate/folinate," which is used to enhance the antitumor effect of the formulation. However, in that case, a stable effect cannot always be expected since it needs a complex active metabolite conversion.
On the other hand, when "arfolitixorin (SP-05)" was used with "fluorouracil," the action of thymidine shortage was enhanced by administering "arfolitixorin (SP-05)," which is the final active metabolite. Thus, it can be expected that the antitumor effect of "fluorouracil" will be enhanced by combining it with "arfolitixorin (SP-05)" more than when combined with "levofolinate/folinate."


As a result of clinical trials up to phase II conducted by Isofol, it has been suggested that "arfolitixorin (SP-05)" enhances the effectiveness of fluorouracil in patients with advanced colorectal cancer (colon and rectal cancers).
Since it does not require a complex metabolic activation, it can be effective not only in treating all patients with advanced colorectal cancer but patients with pancreatic cancer, small intestinal cancer, breast cancer, gastric cancer, etc., too.


(Overview of Isofol)
Isofol is a Swedish biotechnology company researching and developing the drug arfolitixorin, which aims to enhance the efficacy of standard chemotherapy for advanced colorectal cancer and improve tumor response and progression-free survival period. It has a worldwide exclusive license agreement with one of the big pharmaceutical companies, Merck KGaA, Darmstadt, Germany, to develop and commercialize arfolitixorin's cancer indications. Isofol is listed on the Stockholm Stock Exchange.


(Developmental status)
Since December 2018, Isofol has been conducting phase III studies of "arfolitixorin (SP-05)" in the U.S., Canada, Europe, Australia, and Japan. Solasia Pharma will take over the trials in Japan under this licensing agreement and has been conducting the trials since August 2020.
The target number of cases was set at 440-660 and the company planned to conduct interim analysis with 330 cases. The number of cases reached 330 in July 2020, and 440 in December 2020.
In the interim analysis, the Data Safety Monitoring Board, which was established in this trial, was supposed to determine whether or not this trial should be continued based on the evaluation of safety and efficacy and the number of registered subjects (between 440 to 660 cases) if this trial was to be continued. On March 22, 2021, the Board recommended the company to continue the trial with the minimum number of cases being 440, based on the evaluation of safety and effectiveness in interim analysis (Overall Response Rate (ORR) and Progression-Free Survival (PFS)).


The company considers that this recommendation indicates that there is no sign of toxicity enhancement with SP-05, and by continuing the trial without adding cases to the minimum number of cases set in the clinical trial plan: 440 cases, it is possible to achieve ORR, which is a major item for evaluating efficacy, and PFS, which is a secondary evaluation item.
They expect that by continuing the trial with the minimum number of cases, it is possible to proceed with development in the shortest period of time for the next stage to apply SP-05 to actual treatments.


Afterwards, in May 2021 the enrollment of trial subjects was completed in Japan as well, and the enrollment of trial subjects for the whole study was completed. The results of the interim analysis were also confirmed. Following the announcement of the topline results of the phase III clinical trial in the first half of 2022, the company plans to apply to the authorities for approval in the second half of the same year. The company is also working on the licensing-out of rights in Japan, but it is expected to conclude these agreements after the announcement of the top-line results of phase III clinical trial.


In November 2021, Isofol announced that the U.S. Food and Drug Administration (FDA) designated the fast track for advanced colorectal cancer indications to arfolitixorin (SP-05).
The FDA's fast track designation is a system established to promote the development of drugs for serious diseases that fill unmet medical needs and review them promptly. Companies can collaborate closely with the FDA through this process, and sequential review of approval applications is possible. Thus, it provides a chance for a priority review in the U.S. if relevant criteria are met.
Isofol explained that the FDA evaluated the potential of arfolitixorin as a new treatment for advanced colorectal cancer, which has high morbidity and mortality, and decided to grant it the fast track designation.
Solasia Pharma believes that this designation will be an essential step toward providing arfolitixorin (SP-05) to the medical field at an earlier stage.
In addition, Isofol, which is in discussions with the FDA, believes that the release of top-line data for phase III clinical trial is likely to occur in the first half of 2022 as initially planned. Solasia Pharma also has high expectations that it will be able to announce the top-line results of phase III clinical trial in the first half of 2022 and then apply for approval of the authorities in the second half of the same year as scheduled.


Solasia Pharma views SP-05 as a vital drug that could further expand the company's innovative cancer treatment portfolio.
More than 150,000 patients are diagnosed annually with colorectal cancer in Japan. The company plans to provide new treatment options for patients with advanced colorectal cancer in Japan through its development partnership with Isofol.


1-5 Envisioned Growth

The company will forge ahead with the sales and development of the above pipelines as planned, work toward commercialization, and achieve a positive operating profit excluding early R&D expenses. In addition, they will keep engaging in new development and continue to grow, aiming to improve the corporate value and contribute to all stakeholders including patients and shareholders.

1-6 “6 Characteristics” as a Biotech Company

The following 6 points characterize Solasia Pharma as a biotech company:


(1)History of establishment
Solasia Pharma started as “JapanBridge (Ireland) Limited” established jointly by ITOCHU Corporation and MPM Capital, an American VC specializing in bio business, and set up its business by licensing-in new drugs from several biotech companies and propelling development of such drugs.
At first, it mainly considered business transfer to pharmaceutical companies as its exit plan; however, taking account of the business potential and promise, the company shifted its business strategy to persistent business expansion as an independent company and took the path to public stock offering because it was essential to raise funds for research and development. Later, in March 2017, it made a public offering. As the company’s original plan was to sell the company to other companies, the pipelines it owned were comprised of prime assets that could potentially be sold to other companies for encashment even during clinical development. This means that Solasia Pharma has already established a firm business foundation since its inception.


(2) Experienced Clinical development team
Solasia Pharma does not conduct basic research or preclinical trials but in-license assets and specializes in drug creation processes carried out subsequent to the clinical development phase. The most essential thing to achieve in the process of research and development toward commercialization of pharmaceuticals is to eventually obtain approval from the authorities. This requires skills and know-how in the stage of clinical development, especially clinical trials after phase II.
Although there are a number of biotech companies in Japan, CEO Arai stands out with his deep experience and knowledge in clinical development.
The experienced clinical development team, led by CEO Arai, is a significant factor in differentiating Solasia Pharma from other companies and plays a role as a competitive edge.


(3) High rate of successful development
So far, five products including “Sancuso® (SP-01),” “darinaparsin (SP-02)”, “episil® (SP-03)”, “PledOx® (SP-04)”and “arfolitixorin® (SP-05)” were introduced. Four products are commercialized or have reached the final stage towards commercialization.
(Sancuso® (SP-01) was released in China, the application for approval for darinaparsin (SP-02) is in preparation, and episil® (SP-03) was released in Japan, China, and South Korea. As for arfolitixorin® (SP-05), global phase III clinical trial is ongoing.


Such a high rate of successful development is made possible due to the following 2 points: its business model that handles only in-licensed products with a low risk of failure, and its in-house team which can handle all kinds of roles in clinical development. As mentioned above, the development staff is well aware of what are necessary for obtaining approval and therefore can conduct screening of whether or not an in-licensed product will be approved.
Their so-called “connoisseur (for screening pipelines)” has been realized by the combination of the above 2 strengths, and lowers the risk of abandoning development which is the source of such a high success rate.


Analysis of the cash inflow of a new drug based on the discount cash flow (DCF) model has indicated what comprise of a majority of the total cash inflow is not contract money or milestone income, but royalties which, obviously, will be earned only after successful development of the new drug and expansion of the sales volume.


When making a proposal to Pled Pharma (Sweden), Solasia Pharma did not necessarily have advantages over a number of its competitors in terms of prices, including contract money; nevertheless, it succeeded in in-licensing “PledOx®(SP-04).” The reason behind the success is that PledPharma has thought highly of Solasia Pharma’s capabilities, including the strength of the team for producing distinct clinical trial designs, the results of development of the three preceding products, and the business performance in Asia, including Japan and China, reaching a decision that Solasia Pharma will be the best partner that will bring success in “PledOx®” in Asia.
SP-05 has also been highly acclaimed and introduced as a result of these achievements.


(4) Stable business foundation
Solasia Pharma has successfully conducted licensing-out of the sales rights of the aforementioned 4 pipelines to pharmaceutical companies, which means that in combination with the self-selling system, a portfolio for risk hedge has already been established.


(5) Self-selling system for securing large profit
The reason why pharmaceutical companies have succeeded in securing large profit is that they engage in both manufacturing and selling.
At the moment, Solasia Pharma does not own any manufacturing equipment, but the company established a self-selling system to increase profitability in the 3 major cities in China (Beijing, Shanghai, and Guangzhou) which has a large market scale and allows effective sales activities.


(6) Early feasibility of business
Because biotech companies in general post losses in the stage of new drug development, it is not rational to use profit and loss statements for calculating stock prices and enterprise value, and thus the DCF model is used. In case of biotech companies, however, in addition to the discount rate based on “time” which is used in the general DCF model, the success rate for each stage of clinical trials of new drugs is used as another discount rate.
In this case, the most important point is when the company gains approval. Of the five products, “episil® (SP-03)” was already launched in Japan, China and South Korea, and “Sancuso® (SP-01)” was also launched in China, the company has also started preparing to apply for the approval of "darinaparsin (SP-02)." So, the discount rate regarding the company’s development of new drugs should be estimated lower than that of other bio-ventures.


In addition to these six points, the company has high growth potential in the Chinese market.
Understandably, large-scale pharmaceutical companies all over the world have established bases in various Asian countries including China; however, as described in its management policy, Solasia Pharma’s target of development is new products in the field of cancer and rare diseases which major pharmaceutical companies do not enter from the performance-based perspective. Such products, which nowadays attract high attention, were originally developed by biotech companies, and because major companies do not engage in this area, Solasia Pharma will become an invaluable company that can offer access to the thriving Asian market with its self-selling structure in Beijing, Shanghai, and Guangzhou.
In addition, the company concluded a contract for distributorship in China (excluding Hong Kong and Macau) with ITOCHU Corporation, which excels at the business in China and is the largest shareholder, and can utilize the network of ITOCHU, which is a significant advantage for the company. The largest shareholder signed a new outsourcing agreement in February 2020 to utilize the company's extensive functions to run Solasia Pharma's business.
