About PEDMARK (Sodium Thiosulfate (STS))

Cisplatin and other platinum compounds are essential chemotherapeutic components for many pediatric malignancies. Unfortunately, platinum-based therapies cause ototoxicity in many patients, and are particularly harmful to the survivors of pediatric cancer.

In the U.S. and Europe there is estimated that over 10,000 children may receive platinum based chemotherapy. The incidence of hearing loss in these children depends upon the dose and duration of chemotherapy, and many of these children require lifelong hearing aids. There is currently no established preventive agent for this hearing loss and only expensive, technically difficult and sub-optimal cochlear (inner ear) implants have been shown to provide some benefit. Infants and young children at critical stages of development lack speech language development and literacy, and older children and adolescents lack social-emotional development and educational achievement.

STS has been studied by cooperative groups in two Phase 3 clinical studies of survival and reduction of ototoxicity, The Clinical Oncology Group Protocol ACCL0431 and SIOPEL 6. Both studies are completed. The COG ACCL0431 protocol enrolled one of five childhood cancers typically treated with intensive cisplatin therapy for localized and disseminated disease, including newly diagnosed hepatoblastoma, germ cell tumor, osteosarcoma, neuroblastoma, and medulloblastoma. SIOPEL 6 enrolled only hepatoblastoma patients with localized tumors.

Based on results of joint research under TaNeDS*2, an open competition joint discovery research grant program operated by Daiichi Sankyo, the research aims to find and optimize magnetic nanoparticles with high capacity for delivery into tumors, and then study their practical application as a new hyperthermia therapy for cancer treatment by researching an alternating magnetic field generating device for efficiently heating the particles.

To carry out the research, a new company called OiDE RYO-UN, Inc. (head office: Chuo-ku, Tokyo; hereinafter "RYO-UN") has been established and will be wholly funded by the OiDE Fund Investment Limited Partnership ("OiDE Fund") operated by Mitsubishi UFJ Capital.

If the pre-agreed goals of the three-year joint research are achieved, Daiichi Sankyo will purchase all of the stock of RYO-UN in order to continue research and development for the project on its own. Then, at the time of achieving its own goals and after a successful product launch, Daiichi Sankyo will pay considerations to Nagoya City University and Chubu University in the form of royalties.

The research on a new cancer hyperthermia treatment is the third OiDE Fund*3 investment, and Daiichi Sankyo and Mitsubishi UFJ Capital plan to continue to carry out open innovation projects to develop new drug discovery platforms using the OiDE Fund.

*1 New cancer hyperthermia therapy
Cancer hyperthermia therapy makes use of the characteristic that cancer cells have weaker heat resistance than normal cells. This therapy selectively kills cancer cells through heating and there are expectations that it can be combined with radiotherapy, chemotherapy and cancer immunotherapy. The new cancer hyperthermia therapy aims to achieve high safety and efficacy by specifically heating cancer cells at a constant temperature.

*2 TaNeDS
TaNeDS (Take a New Challenge for Drug diScovery) is a collaborative drug discovery initiative being pursued by Daiichi Sankyo in open innovation. This is an open competition joint discovery research grant program whose scope covers research from the exploratory stage to the pre-practical application stage.

"There are no HER2-targeting treatment options currently available for patients with HER2-positive gastric cancer whose tumors are no longer controlled by trastuzumab," said Koichi Akahane, PhD, MBA, Executive Officer, Head of Oncology Function, R&D Division, Daiichi Sankyo. "We look forward to working closely with the Japan Ministry of Health, Labour and Welfare under the terms of the SAKIGAKE program to accelerate the development of DS-8201 particularly since Japan has one of the highest incidence rates of gastric cancer worldwide."

The SAKIGAKE Designation System promotes R&D in Japan, driving early practical application for innovative pharmaceutical products, medical devices and regenerative medicines. As a designated medicine under the SAKIGAKE Designation system, DS-8201 will have prioritized consultation, a dedicated review system to support the development and review process, as well as reduced review time from the normal 12 to 6 months.

"We are pleased that DS-8201 has received SAKIGAKE Designation for advanced HER2-positive gastric cancer, which follows the Breakthrough Therapy and Fast Track designations granted by the U.S. FDA for HER2-positive metastatic breast cancer," said Antoine Yver, MD, MSc, Executive Vice President and Global Head, Oncology Research and Development, Daiichi Sankyo. "These three designations for DS-8201 underscore our commitment to active and close collaborations with health authorities in order to potentially bring DS-8201 as a new treatment option to patients with different types of HER2-expressing cancers worldwide as quickly as possible."

SAKIGAKE Designation was granted based on the results of an ongoing phase 1 study assessing the safety, tolerability and preliminary efficacy of DS-8201. Updated preliminary results of DS-8201 from a subgroup analysis of HER2-positive advanced gastric cancer previously treated with trastuzumab and chemotherapy were recently presented at the 2018 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Gastrointestinal Cancers Symposium.1

Unmet Need in Gastric Cancer
Gastric cancer is the fifth most common cancer worldwide, with nearly one million new cases reported in 2012.2 Approximately half of all gastric cancer cases occur in eastern Asia, with Japan having the third highest incidence rate worldwide.2,3 Gastric cancer is the third leading cause of cancer-related death worldwide, and the second leading cause of cancer-related death in Japan.2,4

Approximately one in five gastric cancers overexpress HER2, a tyrosine kinase receptor growth-promoting protein found on the surface of some cancer cells.5 HER2-expressing gastric cancer is an area of unmet medical need as advances in the treatment of the disease have been limited, largely due to its genetic complexity and heterogeneity.6 Currently, there are no approved HER2-targeting therapy options for patients with HER2-positive advanced gastric cancer after treatment with trastuzumab.

About DS-8201
DS-8201 is the lead product in the investigational ADC Franchise of the Daiichi Sankyo Cancer Enterprise. ADCs are targeted cancer medicines that deliver cytotoxic chemotherapy ("payload") to cancer cells via a linker attached to a monoclonal antibody that binds to a specific target expressed on cancer cells. Designed using Daiichi Sankyo’s proprietary ADC technology, DS-8201 is a smart chemotherapy comprised of a humanized HER2 antibody attached to a novel topoisomerase I inhibitor payload by a tetrapeptide-based linker. It is designed to target and deliver chemotherapy inside cancer cells and reduce systemic exposure to the cytotoxic payload (or chemotherapy) compared to the way chemotherapy is commonly delivered.

DS-8201 is currently in pivotal phase 2 clinical development for HER2-positive unresectable and/or metastatic breast cancer resistant or refractory to T-DM1 (DESTINY-Breast01), pivotal phase 2 development for HER2-positive advanced gastric cancer resistant or refractory to trastuzumab (DESTINY-Gastric01), phase 2 development in advanced colorectal cancer and phase 1 development for other HER2-expressing advanced/unresectable or metastatic solid tumors.

DS-8201 has been granted Breakthrough Therapy designation for the treatment of patients with HER2-positive, locally advanced or metastatic breast cancer who have been treated with trastuzumab and pertuzumab and have disease progression after ado-trastuzumab emtansine (T-DM1), and Fast Track designation for the treatment of HER2-positive unresectable and/or metastatic breast cancer in patients who have progressed after prior treatment with HER2-targeted therapies including T-DM1 by the U.S. Food and Drug Administration (FDA). DS-8201 is an investigational agent that has not been approved for any indication in any country. Safety and efficacy have not been established.

"The FDA acceptance of this application with priority review reinforces our belief in the potential of the Opdivo plus Yervoy combination to treat patients with previously treated metastatic colorectal cancer defined by MSI-H or dMMR biomarkers, and is a result of our longstanding commitment to the exploration of I-O/I-O combinations for patient populations with high unmet need," said Ian M. Waxman, M.D., development lead, Gastrointestinal Cancers, Bristol-Myers Squibb. "We look forward to working with the FDA with the goal of bringing this combination to these colorectal cancer patients."

This application is based on data from the ongoing Phase 2 CheckMate -142 study evaluating the Opdivo and Yervoy combination in previously treated patients with MSI-H or dMMR mCRC. Data from this study were presented in January at the 2018 Gastrointestinal Cancers Symposium and published simultaneously in the Journal of Clinical Oncology.

The FDA’s Breakthrough Therapy Designation is a process intended to enable timely patient access by expediting the development and review of medicines for serious conditions where preliminary clinical evidence indicates a substantial improvement over available therapies on one or more clinically significant endpoints.

About MSI-H or dMMR Colorectal Cancer
Colorectal cancer (CRC) is cancer that develops in the colon or the rectum, which are part of the body’s digestive or gastrointestinal system. In the U.S., CRC is the third most common cancer with more than 140,000 new cases expected to be diagnosed annually, and the third leading cause of cancer-related deaths among men and women combined.
DNA mismatch repair deficiency (dMMR) occurs when the proteins that repair mismatch errors in DNA replication are missing or non-functional, leading to microsatellite instability-high (MSI-H) tumors. Approximately 15% of CRC patients and 4-5% of metastatic CRC patients have MSI-H or dMMR biomarkers. Patients with MSI-H or dMMR metastatic CRC are less likely to benefit from conventional chemotherapy and typically have a poor prognosis. Routine testing to confirm MSI-H or dMMR status should be conducted for all CRC patients.

Bristol-Myers Squibb & Immuno-Oncology: Advancing Oncology Research
At Bristol-Myers Squibb, patients are at the center of everything we do. Our vision for the future of cancer care is focused on researching and developing transformational Immuno-Oncology (I-O) medicines for hard-to-treat cancers that could potentially improve outcomes for these patients.

We are advancing the scientific understanding of I-O through our extensive portfolio of investigational compounds and approved agents. Our differentiated clinical development program is studying broad patient populations across more than 50 types of cancers with 14 clinical-stage molecules designed to target different immune system pathways. Our deep expertise and innovative clinical trial designs position us to advance I-O/I-O, I-O/chemotherapy, I-O/targeted therapies and I-O/radiation therapies across multiple tumors and potentially deliver the next wave of therapies with a sense of urgency. Through our leading translational capabilities, we are pioneering immune biology research and identifying a number of potentially predictive biomarkers, including PD-L1, TMB, MSI-H/dMMR and LAG-3, advancing the possibility of precision medicine for more patients with cancer.

We understand making the promise of I-O a reality for the many patients who may benefit from these therapies requires not only innovation on our part but also close collaboration with leading experts in the field. Our partnerships with academia, government, advocacy and biotech companies support our collective goal of providing new treatment options to advance the standards of clinical practice.

About Opdivo
Opdivo is a programmed death-1 (PD-1) immune checkpoint inhibitor that is designed to uniquely harness the body’s own immune system to help restore anti-tumor immune response. By harnessing the body’s own immune system to fight cancer, Opdivo has become an important treatment option across multiple cancers.
Opdivo’s leading global development program is based on Bristol-Myers Squibb’s scientific expertise in the field of Immuno-Oncology and includes a broad range of clinical trials across all phases, including Phase 3, in a variety of tumor types. To date, the Opdivo clinical development program has enrolled more than 25,000 patients. The Opdivo trials have contributed to gaining a deeper understanding of the potential role of biomarkers in patient care, particularly regarding how patients may benefit from Opdivo across the continuum of PD-L1 expression.
In July 2014, Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world. Opdivo is currently approved in more than 60 countries, including the United States, the European Union and Japan. In October 2015, the Company’s Opdivo and Yervoy combination regimen was the first Immuno-Oncology combination to receive regulatory approval for the treatment of metastatic melanoma and is currently approved in more than 50 countries, including the United States and the European Union.

OPDIVO can cause immune-mediated encephalitis. Evaluation of patients with neurologic symptoms may include, but not be limited to, consultation with a neurologist, brain MRI, and lumbar puncture. Withhold OPDIVO in patients with new-onset moderate to severe neurologic signs or symptoms and evaluate to rule out other causes. If other etiologies are ruled out, administer corticosteroids and permanently discontinue OPDIVO for immune-mediated encephalitis. In patients receiving OPDIVO monotherapy, encephalitis occurred in 0.2% (3/1994) of patients. Fatal limbic encephalitis occurred in one patient after 7.2 months of exposure despite discontinuation of OPDIVO and administration of corticosteroids. Encephalitis occurred in one patient receiving OPDIVO with YERVOY (0.2%) after 1.7 months of exposure.

Other Immune-Mediated Adverse Reactions
Based on the severity of the adverse reaction, permanently discontinue or withhold OPDIVO, administer high-dose corticosteroids, and, if appropriate, initiate hormone-replacement therapy. Across clinical trials of OPDIVO monotherapy or in combination with YERVOY, the following clinically significant immune-mediated adverse reactions, some with fatal outcome, occurred in <1.0% of patients receiving OPDIVO: myocarditis, rhabdomyolysis, myositis, uveitis, iritis, pancreatitis, facial and abducens nerve paresis, demyelination, polymyalgia rheumatica, autoimmune neuropathy, Guillain-Barré syndrome, hypopituitarism, systemic inflammatory response syndrome, gastritis, duodenitis, sarcoidosis, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), motor dysfunction, vasculitis, and myasthenic syndrome.

If uveitis occurs in combination with other immune-mediated adverse reactions, consider a Vogt-Koyanagi-Harada-like syndrome, which has been observed in patients receiving OPDIVO and may require treatment with systemic steroids to reduce the risk of permanent vision loss.

Infusion Reactions
OPDIVO can cause severe infusion reactions, which have been reported in <1.0% of patients in clinical trials. Discontinue OPDIVO in patients with Grade 3 or 4 infusion reactions. Interrupt or slow the rate of infusion in patients with Grade 1 or 2. In patients receiving OPDIVO monotherapy as a 60-minute infusion, infusion-related reactions occurred in 6.4% (127/1994) of patients. In a separate study in which patients received OPDIVO monotherapy as a 60-minute infusion or a 30-minute infusion, infusion-related reactions occurred in 2.2% (8/368) and 2.7% (10/369) of patients, respectively. Additionally, 0.5% (2/368) and 1.4% (5/369) of patients, respectively, experienced adverse reactions within 48 hours of infusion that led to dose delay, permanent discontinuation or withholding of OPDIVO. In patients receiving OPDIVO as a 60-minute infusion prior to the infusion of YERVOY, infusion-related reactions occurred in 2.5% (10/407) of patients.

Complications of Allogeneic HSCT after OPDIVO
Complications, including fatal events, occurred in patients who received allogeneic HSCT after OPDIVO. Outcomes were evaluated in 17 patients from Checkmate 205 and 039, who underwent allogeneic HSCT after discontinuing OPDIVO (15 with reduced-intensity conditioning, 2 with myeloablative conditioning). Thirty-five percent (6/17) of patients died from complications of allogeneic HSCT after OPDIVO. Five deaths occurred in the setting of severe or refractory GVHD. Grade 3 or higher acute GVHD was reported in 29% (5/17) of patients. Hyperacute GVHD was reported in 20% (n=2) of patients. A steroid-requiring febrile syndrome, without an identified infectious cause, was reported in 35% (n=6) of patients. Two cases of encephalitis were reported: Grade 3 (n=1) lymphocytic encephalitis without an identified infectious cause, and Grade 3 (n=1) suspected viral encephalitis. Hepatic veno-occlusive disease (VOD) occurred in one patient, who received reduced-intensity conditioned allogeneic HSCT and died of GVHD and multi-organ failure. Other cases of hepatic VOD after reduced-intensity conditioned allogeneic HSCT have also been reported in patients with lymphoma who received a PD-1 receptor blocking antibody before transplantation. Cases of fatal hyperacute GVHD have also been reported. These complications may occur despite intervening therapy between PD-1 blockade and allogeneic HSCT.
Follow patients closely for early evidence of transplant-related complications such as hyperacute GVHD, severe (Grade 3 to 4) acute GVHD, steroid-requiring febrile syndrome, hepatic VOD, and other immune-mediated adverse reactions, and intervene promptly.

Embryo-Fetal Toxicity
Based on their mechanisms of action, OPDIVO and YERVOY can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with an OPDIVO- or YERVOY- containing regimen and for at least 5 months after the last dose of OPDIVO.
Lactation
It is not known whether OPDIVO or YERVOY is present in human milk. Because many drugs, including antibodies, are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from an OPDIVO-containing regimen, advise women to discontinue breastfeeding during treatment. Advise women to discontinue nursing during treatment with YERVOY and for 3 months following the final dose.

Serious Adverse Reactions
In Checkmate 037, serious adverse reactions occurred in 41% of patients receiving OPDIVO (n=268). Grade 3 and 4 adverse reactions occurred in 42% of patients receiving OPDIVO. The most frequent Grade 3 and 4 adverse drug reactions reported in 2% to <5% of patients receiving OPDIVO were abdominal pain, hyponatremia, increased aspartate aminotransferase, and increased lipase.

Dr. Sergio Quezada, Group Leader and Cancer Research UK Senior Research Fellow at The UCL Cancer Institute, and Chairman of Tusk Therapeutics’ Scientific Advisory Board, will deliver the oral presentation at 10.30am on Monday 16th April. The presentation will focus on Tusk Therapeutics’ first-in-class anti-CD25 antibody programme which is built on novel biology discovered by Tusk Therapeutics in collaboration with Dr. Quezada and his team at University College London. Tusk Therapeutics, Cancer Research UK (via its Commercial Partnerships Team) and UCL announced in 2017, an exclusive licensing and collaboration deal to develop and commercialise antibody-based therapeutics against CD25.

Commenting on the presentations, Luc Dochez, Chief Executive Officer of Tusk Therapeutics said: "We are excited to be presenting data at the upcoming AACR (Free AACR Whitepaper) meeting, in particular, to share data on the unique mechanism behind our anti-CD25 programme. It is well accepted that regulatory T-cells play an important role in immune-suppression in cancer but, thus far, nobody has been able to target Tregs effectively. Based on the pre-clinical proof-of-concept data generated in collaboration with Cancer Research UK and University College London, we

have shown that our novel approach can successfully target Tregs and therefore we believe that Tusk Therapeutics’ anti-CD25 antibody could become an important player in the immuno-oncology field."
