In addition, licensing agreement that grants exclusive option rights concerning the worldwide development, manufacturing and marketing of Telomelysin, excluding Japan, Taiwan, China, Hong Kong and Macau to Chugai has also been concluded. Moreover, both companies agreed that Oncolys will newly issue common stock worth approximately 800 million yen, and Chugai will accept all the stocks.

Chugai shall pay 550 million yen as an upfront payment for the exclusive licensing agreement, with sublicensing rights, in Japan and Taiwan. If a certain level of efficacy has been confirmed in the clinical study of Telomelysin, and in case Chugai exercised the exclusive option rights described above, the total value of the licensing agreement which Chugai shall pay to Oncolys will be 50 billion yen or more. In addition, after the launch of Telomelysin, Chugai shall pay to Oncolys, sales royalties according to Chugai’s amount of sales of Telomelysin, apart from the total value of the licensing agreement.

Comments by the Management
Yasuo Urata, President & CEO, Oncolys BioPharma Inc.
“Chugai is an expert in the development of oncology drugs including antibody pharmaceuticals, and we feel that we were able to form the best partnering in developing Telomelysin, an oncolytic viral immunotherapy. Telomelysin is an oncolytic virus drug originated in Japan, and we are extremely delighted that Chugai had highly valued the clinical effects of the drug against esophageal cancer. We hope that Chugai will greatly expand the indications of Telomelysin, going forward.”

Tatsuro Kosaka, President and CEO, Chugai Pharmaceutical Co., Ltd.
“Telomelysin is an oncolytic viral immunotherapy with a novel mode of action, expected to provide new value to oncology patients. We are committed to maximize the value of this new innovative drug created by Oncolys in order to deliver it to patients as quickly as possible, and also expand its indications to other types of cancer, by considering the combination with cancer immunotherapies, which could provide true value to patients and their families. We strongly believe that Chugai, as one of the shareholders of Oncolys, can contribute to increasing corporate and shareholder values of Oncolys in the medium- to long-term perspective.”

Oncolys believes that the conclusion of this licensing agreement and the third-party allocation of shares will contribute to enhancing its corporate value as well as shareholder value. At this point, however, the concrete amount of impact they would have on Oncolys’ business performance of the term ending December 2019 is unclear. The impact on the consolidated financials for the fiscal year ending December 2019 of Chugai is expected to be minimal.
As written in the financial statements for the business term ended December 2018, released on February 8, 2019, Oncolys has not announced its business performance forecasts for the term ending December 2019, since the company views it difficult to calculate appropriate and reasonable numerical value due to the existence of numerous uncertain factors that impact the business performance at this point.

About Telomelysin (OBP-301)
Telomelysin or OBP-301 is genetically modified type 5 adenovirus which can specifically replicate in and destroy cancer cells. Type 5 adenovirus causes common cold symptoms and exists in nature. We are anticipating that Telomelysin may induce strong anti-tumor activity after causing oncolysis by specific replication in cancer cells and may be safe because of its low replication ability in normal cells. In addition, serious adverse reactions such as vomiting, hair loss and hematopoietic disorders have not been reported in clinical studies we conducted so far, and thus it is expected to improve patients’ Quality of Life (QOL). Furthermore, recent publication in clinic showed that cancer cells destroyed by virotherapy may enhance cancer immunity by directly transmitting the signal of their specific antigen to immune cells such as dendritic cells. Therefore, we are expecting that Telomelysin in combination with an immune checkpoint inhibitor such as anti-PD-1 antibody may have a systemic anti-cancer efficacy together with good local control. Oncolys and Medigen Biotechnology Corp. in Taiwan had long-term collaborative relationship for the development of Telomelysin.
