Napabucasin is currently being investigated in phase 3 studies – CanStem303C for metastatic colorectal cancer (NCT02753127) and CanStem111P for metastatic pancreatic cancer (NCT02993731). Included in the napabucasin studies that will be presented at ASCO (Free ASCO Whitepaper) are data from a phase 1b/2 trial in patients with metastatic pancreatic cancer (Poster, Bekaii-Saab, 6/3, 8 a.m. – 11:30 a.m.). Boston Biomedical, Inc. will also present detailed findings from the phase 3 BRIGHTER trial evaluating the efficacy and safety of napabucasin plus paclitaxel for pretreated advanced gastric and gastroesophageal junction adenocarcinoma (Poster discussion, Shah, 6/3, 4:45 p.m. – 6 p.m.). Last year, the Company announced that the study was unblinded early after the Data and Safety Monitoring Board (DSMB) determined that the study was unlikely to reach its primary endpoint. No safety concerns were identified by the DSMB. Separately, data with napabucasin in advanced thymoma and thymic carcinoma, rare tumor types, is available as an online publication.

DSP-7888 is being evaluated in several early and mid-stage studies across multiple tumor types. The Company will present the study design of a phase 2 study of DSP-7888 in combination with bevacizumab for recurrent or progressive glioblastoma, WIZARD201G (Poster, de Groot, 6/2, 1:15 p.m. – 4:45 p.m.), which recently began enrolling patients (NCT03149003).

"As our pipeline and clinical development program continues to evolve, we are looking forward to sharing our learnings with the scientific community at the ASCO (Free ASCO Whitepaper) annual meeting," said Patricia S. Andrews, Chief Executive Officer, Boston Biomedical, Inc.

About Napabucasin

Napabucasin is an orally-administered investigational agent that affects multiple oncogenic cellular pathways, including inhibition of the STAT3 pathway, which has been implicated in viability of cancer cells and cancer cells with stemness phenotypes.

Napabucasin is currently being investigated in CanStem303C, a phase 3 study for metastatic colorectal cancer (NCT02753127) and CanStem111P, a phase 3 study for metastatic pancreatic cancer (NCT02993731). It is also being investigated in earlier phases in multiple solid and hematologic malignancies. In 2016, the U.S. Food and Drug Administration granted Orphan Drug Designation for napabucasin in pancreatic cancer.

About DSP-7888 (ombipepimut-S*)

DSP-7888 is an investigational cancer peptide vaccine containing peptides that induce WT1-specific cytotoxic T lymphocytes (WT1-CTL) and helper T cells to attack WT1-expressing cancerous cells found in various types of hematologic and solid tumors. Researchers have identified that by adding helper T cell inducing peptides, improved outcomes may be achieved compared to a killer peptide treatment regimen alone.

DSP-7888 is currently being investigated in three Wizard201G monotherapy studies: a phase 1/2 study in myelodysplastic syndrome (MDS) (NCT02436252), a phase 1/2 study in pediatric patients with relapsed or refractory high grade gliomas (NCT02750891) and a phase 1 study in advanced malignancies (NCT02498665). DSP-7888 is currently being investigated in combination with bevacizumab in a phase 2 study in patients with recurrent or progressive glioblastoma (NCT03149003) and in a phase 1 study in combination with nivolumab or atezolizumab in patients with advanced solid tumors (NCT03311334). In 2017, the U.S. Food and Drug Administration granted Orphan Drug Designations for DSP-7888 in MDS and brain cancer. More information on DSP-7888 and ongoing clinical studies can be found at www.BostonBiomedical.com.

Notes to editors

About Pexa-Vec
Pexa-Vec (JX594) is an oncolytic immunotherapeutic based on an oncolytic vaccinia virus armed with a GM-CSF gene that promotes an anti-tumor immune response. Pexa-Vec is designed to selectively target and destroy cancer cells through three different mechanisms of action: selectively destroy cancer cells through the direct lysis (breakdown) of cancer cells through viral replication, reduce the blood supply to tumors through vascular disruption, and stimulate the body’s immune response against cancer cells.
Pexa-Vec is currently being evaluated in a Phase 3 trial in hepatocellular carcinoma (HCC, liver cancer) in combination with sorafenib (current standard of care). Other trials evaluating the oncolytic virus in solid tumors are underway and expected to readout in 2018, including a Phase 2 trial in combination with nivolumab (HCC).
Transgene has exclusive rights to develop and commercialize Pexa-Vec for the treatment of solid tumors in Europe. Its partner SillaJen, Inc. is focused on developing Pexa-Vec for the North American market and has also granted exclusive development and commercial rights to Pexa-Vec in Hong Kong and The People’s Republic of China to Lee’s Pharmaceutical.

About Ropotrectinib (TPX-0005)

Ropotrectinib (TPX-0005) is a potent and orally bioavailable investigational small molecule kinase inhibitor for ALK, ROS1, and TRK family. The clinical benefits of targeting ALK, ROS1, or TRK fusion kinase have been demonstrated with multiple kinase inhibitors already approved for the treatment of ALK+ non-small cell lung cancer (NSCLC), in addition to crizotinib for ROS1+ NSCLC, and larotrectinib and entrectinib in clinical studies for TRK+ cancers. The successes of these therapies are overshadowed by the development of acquired resistance. The acquired solvent front mutations including ALK G1202R, ROS1 G2032R, TRKA G595R and TRKC G623R render a common clinical resistance to the current ALK, ROS1, and TRK inhibitors. TPX-0005 is a potent kinase inhibitor against wildtype and mutated ALK, ROS1 and TRK family kinases, especially the clinically significant solvent front mutations, gatekeeper mutations, and emerging compound mutations after multiple line treatments. Ropotrectinib may provide new opportunities in the clinic to inhibit the abnormal signaling of ALK, ROS1, or TRK family in solid malignancies, and overcome resistance seen in refractory patients. TPX-0005 is currently being evaluated in a Phase 1/2, open-label, multi-center, first-in-human study of the safety, tolerability, pharmacokinetics and anti-tumor activity in patients with advanced solid tumors harboring ALK, ROS1, or NTRK1-3 rearrangements (TRIDENT-1, NCT03093116). For additional information about ropotrectinib trial, please refer to www.clinicaltrials.gov. Interested patients and physicians can also contact the TP Therapeutics Oncology Clinical Trial Hotline at 1-858-276-0005 or email [email protected].

On May 17, 2018 Exelixis, Inc. (Nasdaq:EXEL) reported that its partner Ipsen received approval from the European Commission (EC) for CABOMETYX (cabozantinib) 20 mg, 40 mg and 60 mg for the first-line treatment of adults with intermediate- or poor-risk advanced renal cell carcinoma (RCC) in the European Union (Press release, Exelixis, MAY 17, 2018, View Source;p=irol-newsArticle&ID=2349524 [SID1234526729]).

"The expanded marketing authorization of CABOMETYX to include previously untreated patients in Europe with intermediate- or poor-risk advanced kidney cancer is an exciting milestone for a patient population in need of more treatment options," said Michael M. Morrissey, Ph.D., President and Chief Executive Officer of Exelixis. "We look forward to our continued collaboration with our partners Ipsen and Takeda to bring new options to more patients with difficult-to-treat cancers in Europe and around the world."

Under the terms of the Collaboration and License Agreement with Ipsen, Exelixis will receive a milestone payment of $50 million for the EC approval, of which approximately $46 million was recognized as collaboration revenue in the first quarter of 2018. The payment will be made by Ipsen within the next 70 days.

CABOMETYX was approved in the European Union in September 2016 for the treatment of advanced RCC in adults following prior vascular endothelial growth factor (VEGF)-targeted therapy. The expanded EC approval to include first-line treatment is based on results of the CABOSUN trial, which met its primary endpoint of improved progression-free survival (PFS) compared with sunitinib in patients with previously untreated advanced RCC determined to be intermediate- or poor-risk by the International Metastatic RCC Database Consortium (IMDC) criteria. In December 2017, the U.S. Food and Drug Administration (FDA) approved CABOMETYX for the expanded indication of patients with advanced RCC based on the results from the CABOSUN trial.

About the CABOSUN Study

On May 23, 2016, Exelixis announced that the phase 2 CABOSUN study met its primary endpoint, demonstrating a statistically significant and clinically meaningful improvement in PFS compared with sunitinib in patients with advanced intermediate- or poor-risk RCC as determined by investigator assessment. The CABOSUN study was conducted by The Alliance for Clinical Trials in Oncology and was sponsored by the National Cancer Institute-Cancer Therapy Evaluation Program (NCI-CTEP) under the Cooperative Research and Development Agreement with Exelixis for the development of cabozantinib. These results were first presented by Dr. Toni Choueiri at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) 2016 Congress, and published in the Journal of Clinical Oncology (Choueiri, JCO, 2016).1 In June 2017, a blinded independent radiology review committee (IRC) confirmed that cabozantinib provided a clinically meaningful and statistically significant improvement in the primary efficacy endpoint of investigator-assessed PFS. Results from the IRC review were presented by Dr. Toni Choueiri at the ESMO (Free ESMO Whitepaper) 2017 Congress.

CABOSUN was a randomized, open-label, active-controlled phase 2 trial that enrolled 157 patients with advanced RCC determined to be intermediate- or poor-risk by the IMDC criteria. Patients were randomized 1:1 to receive cabozantinib (60 mg once daily) or sunitinib (50 mg once daily, 4 weeks on followed by 2 weeks off). The primary endpoint was PFS. Secondary endpoints included overall survival, objective response rate and safety. Eligible patients were required to have locally advanced or metastatic clear-cell RCC, ECOG performance status 0-2 and had to be intermediate- or poor-risk per the IMDC criteria (Heng, JCO, 2009).2 Prior systemic treatment for RCC was not permitted.

About Advanced Renal Cell Carcinoma

The American Cancer Society’s 2018 statistics cite kidney cancer as among the top ten most commonly diagnosed forms of cancer among both men and women in the U.S.3 Clear cell RCC is the most common type of kidney cancer in adults.4 If detected in its early stages, the five-year survival rate for RCC is high; for patients with advanced or late-stage metastatic RCC, however, the five-year survival rate is only 12 percent, with no identified cure for the disease.3 Approximately 30,000 patients in the U.S. and 68,000 globally require treatment, and an estimated 14,000 patients in the U.S. each year are in need of a first-line treatment for advanced kidney cancer.5

The majority of clear cell RCC tumors have lower than normal levels of a protein called von Hippel-Lindau, which leads to higher levels of MET, AXL and VEGF.6,7 These proteins promote tumor angiogenesis (blood vessel growth), growth, invasiveness and metastasis.8,9,10,11 MET and AXL may provide escape pathways that drive resistance to VEGF receptor inhibitors.7,8

About CABOMETYX (cabozantinib)

CABOMETYX tablets are approved in the United States for the treatment of patients with advanced RCC. CABOMETYX tablets are also approved in the European Union, Norway, Iceland, Australia, Switzerland and South Korea for the treatment of advanced RCC in adults who have received prior VEGF-targeted therapy, and in the European Union for previously untreated intermediate- or poor-risk advanced RCC. Regulatory applications were recently submitted for CABOMETYX for additional advanced hepatocellular carcinoma (HCC) indications: on March 15, 2018, Exelixis announced the completed submission of a supplemental New Drug Application to the U.S. FDA for CABOMETYX for previously treated patients with advanced HCC; on March 28, 2018, Ipsen announced that the European Medicines Agency validated its application for a new indication for cabozantinib as a treatment for previously treated advanced hepatocellular carcinoma in the European Union.

In 2016, Exelixis granted Ipsen exclusive rights for the commercialization and further clinical development of cabozantinib outside of the United States and Japan. In 2017, Exelixis granted exclusive rights to Takeda Pharmaceutical Company Limited for the commercialization and further clinical development of cabozantinib for all future indications in Japan, including RCC.
