ONC201 Trial Begins at NYU for Children with H3 K27M Mutant Glioma

On January 31, 2018 Oncoceutics, Inc. reported that the first patient has been treated in a clinical trial of ONC201 for pediatric patients with brain tumors that contain a specific mutation called the histone H3 K27M mutation (Press release, Oncoceutics, JAN 31, 2018, View Source [SID1234558373]). The trial, which will treat patients with recurrent high-grade gliomas, including glioblastoma and diffuse intrinsic pontine glioma (DIPG), is led by Sharon Gardner, MD, a pediatric neuro-oncologist at NYU Langone Health’s Stephen D. Hassenfeld Children’s Center for Cancer & Blood Disorders. The study will enroll approximately 45 pediatric patients using ONC201 as a single agent or in combination with radiotherapy for patients with recurrent or newly diagnosed disease, respectively.

The H3 K27M mutation has been identified as an important prognostic indicator in aggressive midline gliomas that involve specific parts of the brain, including the thalamus, pons, or spinal cord. In 2016, the World Health Organization categorized any midline brain tumor that contains the H3 K27M mutation as the highest grade (IV) because the mutation confers such a poor prognosis. Beyond palliative radiation, no medical therapy has been shown to provide clinical benefit for patients with this mutation in their tumor. Pediatric patients are particularly impacted by this mutation, especially those with DIPG where 70-80% of the patients have the mutation.

As previously announced, the company’s focus on H3 K27M mutual gliomas arose from success with a patient in the first group of its phase II trial for recurrent glioblastoma conducted at Harvard. This patient, a 22-year old woman, had the H3 K27M mutation and has experienced a 96% reduction in tumor size. She remains on therapy today (after 22 months) and has returned to her normal activities. Based on the strong result for this patient, Oncoceutics enrolled additional brain tumor patients with the H3 K27M mutation, and some of these patients have also done well, including a patient whose tumors have completely disappeared. In addition to enrolling more adult patients with the H3 K27M mutation at Harvard (where the trial was limited to adults), we have enrolled a handful of children with brain tumors that have the mutation under compassionate use protocols, special permission from the FDA to enroll patients on a case-by-case when there is no approved clinical trial accessible to the patient. We have also seen signs of efficacy in these children. In total, 14 patients with brain tumors that have the H3 K27M mutation have been treated with single agent ONC201 (7 in formal clinical studies and 7 in compassionate use studies), and five of these patients have demonstrated clinical and/or radiographic benefit from ONC201 therapy. These data will be reported in upcoming scientific conferences and publications. In addition, corroborating preclinical efficacy and mechanistic studies from the lab of Andrew Chi, MD, also at NYU Langone Health, have shown that H3 K27M gliomas cells are extremely sensitive to ONC201.

"The previously reported responses to ONC201 in patients with H3 K27M gliomas, combined with the preclinical results from Dr. Chi’s lab here at NYU, make me excited to offer ONC201 to our patients with this molecularly-defined disease," said Dr. Gardner. "To date, no drugs have proven effective in these tumors, and this patient population is in need of novel therapeutic options.

"We are excited to expand our existing clinical program targeted at patients with the H3 K27M mutation to the pediatric populations," said Lee Schalop, MD, Chief Operating Officer at Oncoceutics. "Based on the results we have seen in patients with the H3 K27M tumor mutation who have received ONC201, as well as the preclinical data generated by Dr. Chi, we believe that ONC201 offers a unique opportunity to eliminate these devastating tumors."

Puma Biotechnology Announces Publication of Results from Phase II SUMMIT ‘Basket’ Trial Evaluating Neratinib in HER2 and HER3 Mutant Cancers

On January 31 Puma Biotechnology, Inc. (NASDAQ: PBYI), a biopharmaceutical company, announced that initial results from the company’s ongoing SUMMIT Phase II ‘basket’ clinical trial of PB272 (neratinib) in patients with tumors harboring HER2 or HER3 mutations were published in the journal Nature . The paper, "HER kinase inhibition in patients with HER2- and HER3-mutant cancers," appears in the January 31, 2018 online issue at View Source and will be published in a future print issue of the journal.

The Phase II SUMMIT trial is a global, multi-histology, open-label, precision-medicine ‘basket’ study evaluating the safety and efficacy of neratinib administered daily to patients with a wide variety of solid tumors with activating HER2 or HER3 mutations. SUMMIT is designed to evaluate the contributions of both genetic mutation and cancer type on individual patients’ response to neratinib. Information generated from the trial will help guide neratinib-based targeted therapy across a broad spectrum of tumor types with HER2 or HER3 mutations, including patients with rare tumors who may not otherwise have access to investigational therapies.

"Publication of the initial SUMMIT data in this prestigious journal reflects the novelty and quality of this precision-medicine trial design, as well as the growing understanding that both tumor type and gene mutations play an important role in individual patients’ response to cancer therapies such as neratinib," said Alan H. Auerbach, Puma’s Chief Executive Officer and President. "The basket trial design utilized for SUMMIT is enabling researchers to evaluate the clinical potential of neratinib in multiple cancer types, rather than limiting exploration to one tumor type at a time. SUMMIT is also significant in that it will provide the largest body of clinical data to date on the use of an irreversible pan-HER inhibitor in patients who have solid tumors with somatic HER2 or HER3 mutations."

The initial SUMMIT results published in Nature comprise data from 141 patients enrolled in the neratinib monotherapy arm of the trial, including 124 patients with HER2 mutations and 17 patients with HER3 mutations. This included patients with 21 unique tumor types, with the most common being breast, lung, bladder and colorectal cancer. Researchers observed 30 distinct HER2 and 12 distinct HER3 mutations among these patients, with the most frequent HER2 variants involving amino acids S310, L755, A755_G776insYVMA and V777.

In the HER2-mutant cohort, clinical responses were observed in tumors with S310, L755, V777, P780_Y781insGSP and A775_G776insYVMA mutations. When stratified by tumor type, responses were observed in patients with breast, cervical, biliary, salivary and non-small-cell lung cancers, which led to cohort expansions in these tumor types. No activity was observed in the HER3-mutant cohort.

The neratinib safety profile observed in the SUMMIT study is consistent with that observed previously in metastatic patients with HER2 amplified tumors. The study showed that the most frequently observed adverse reaction was diarrhea. All patients in the SUMMIT study received prophylactic loperamide (16 mg per day initially) for the first cycle of treatment in order to reduce neratinib-related diarrhea, and with this anti-diarrheal prophylaxis and management, diarrhea was not a treatment-limiting side effect in SUMMIT. For the 141 patients enrolled in the neratinib monotherapy arm with safety data available, 31 patients (22.0%) reported grade 3 diarrhea. The median duration of grade 3 diarrhea for those patients was two days. Four patients (2.8%) permanently discontinued neratinib and 21 patients (14.9%) had dose interruptions due to diarrhea.

"Results to date from the SUMMIT trial validate the ‘next-generation’ basket trial approach, which has enabled us to efficiently and effectively evaluate neratinib across numerous cancer types as well as individual and sometimes entirely novel HER2 mutations," said David Hyman, M.D., Chief of the Early Drug Development Service at Memorial Sloan Kettering Cancer Center (MSK). "We look forward to completing enrollment in the ongoing cohorts in the study and continuing to utilize the basket trial design to explore the most optimal treatment options for these select patient populations."

Dr. Hyman, who helped pioneer the concept of basket trials at MSK, presented the initial findings from the SUMMIT study at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting in April 2017.

"We are very pleased with these initial results," said Mr. Auerbach. "We look forward to advancing neratinib into further clinical development in multiple HER2 mutant tumor types, both as monotherapy and in novel combinations."

Seattle Genetics to Acquire Cascadian Therapeutics, Adding Late-Stage Breast Cancer Program to Its Oncology Pipeline

On January 31, 2018 Seattle Genetics, Inc. (Nasdaq:SGEN) and Cascadian Therapeutics, Inc. (Nasdaq:CASC) reported the signing of a definitive merger agreement under which Seattle Genetics has agreed to acquire Cascadian Therapeutics (Press release, Cascadian Therapeutics, JAN 31, 2018, View Source [SID1234523651]). Under the terms of the agreement, Seattle Genetics will pay $10.00 per share in cash, or approximately $614 million. The transaction was unanimously approved by the Boards of Directors of both companies.

Cascadian Therapeutics’ most advanced program is tucatinib, an investigational oral, small molecule tyrosine kinase inhibitor (TKI) that is highly selective for HER2, a growth factor receptor that is overexpressed in multiple cancers, including breast, colorectal, ovarian and gastric. Tucatinib is currently being evaluated in a randomized global pivotal trial called HER2CLIMB for patients with HER2-positive (HER2+) metastatic breast cancer, including patients with or without brain metastases. Tucatinib has been evaluated as a single agent and in combination with both chemotherapy and other HER2-directed agents including Herceptin (trastuzumab) and Kadcyla (trastuzumab emtansine). Results from phase 1b trials showed that the combination of tucatinib, capecitabine and trastuzumab was generally well-tolerated and demonstrated clinical activity in patients with and without brain metastases. The data support the ongoing pivotal trial and the potential role of tucatinib in earlier lines of metastatic breast cancer.

"This acquisition would enhance our late-stage clinical pipeline with a potentially best-in-class, orally available and highly selective TKI for patients with HER2-positive metastatic breast cancer," said Clay Siegall, Ph.D., President and Chief Executive Officer of Seattle Genetics. "Tucatinib would complement our existing pipeline of targeted cancer therapies, provide a third late-stage opportunity for a commercial product in solid tumors and expand our global efforts in breast cancer. It also leverages our broad expertise and resources to advance and expand the tucatinib program for patients. Beyond breast cancer, we believe there may be opportunities for tucatinib in other tumor types, such as HER2-positive metastatic colorectal cancer. Cascadian’s pipeline also includes a preclinical immuno-oncology agent. We look forward to welcoming the team at Cascadian Therapeutics and continuing the momentum of the tucatinib development program."

"This agreement represents a very positive outcome for patients with HER2-expressing cancers, our employees and for our stockholders," said Scott D. Myers, President and Chief Executive Officer of Cascadian Therapeutics. "Seattle Genetics has the development and commercial capabilities and the resources needed to more fully realize the potential of tucatinib as a new best-in-class treatment option for metastatic breast cancer, colorectal cancer and potentially for other indications."

Terms of the Transaction

Under the terms of the definitive merger agreement, Seattle Genetics will commence a tender offer on or about February 8, 2018 to acquire all of the outstanding shares of common stock of Cascadian Therapeutics for $10 per share in cash. This represents a 69 percent premium to the closing price of Cascadian Therapeutics’ common stock on Tuesday, January 30, 2018, and a 139 percent premium to its 30-day volume weighted average stock price. The tender offer is subject to customary closing conditions, including the tender of at least a majority of the outstanding shares of Cascadian Therapeutics common stock (on a fully diluted basis) and the expiration or early termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. Following the closing of the tender offer, a wholly-owned subsidiary of Seattle Genetics will merge with and into Cascadian Therapeutics, with each share of Cascadian Therapeutics common stock that has not been tendered being converted into the right to receive the same $10 per share in cash offered in the tender offer. The transaction is anticipated to close in the first quarter of 2018.

In connection with the transaction, Seattle Genetics has secured a financing commitment in the amount of $400 million from Barclays and JPMorgan-Chase Bank. The balance of the consideration will be provided from cash on hand.

Leerink Partners LLC is acting as lead financial advisor to Seattle Genetics. Barclays and J.P. Morgan Securities LLC are also acting as financial advisors on the transaction. Perella Weinberg Partners LP is acting as financial advisor to Cascadian Therapeutics. Legal counsel for Seattle Genetics is Sullivan & Cromwell LLP and legal counsel for Cascadian Therapeutics is Reed Smith LLP. Goodwin Procter LLP acted as special counsel for the Cascadian Therapeutics Board of Directors and Board transaction committee.

Seattle Genetics Preliminary Financial Results

In conjunction with today’s announcement, Seattle Genetics separately reported preliminary unaudited consolidated financial results as of and for the quarter and year ended December 31, 2017 as follows:

Three Months Ended December 31, 2017 Year Ended December 31, 2017
Total revenues $128 million to $130 million $481 million to $483 million

ADCETRIS net product sales in the U.S. and Canada $82 million to $84 million $306 million to $308 million

Total revenues increased from the comparable periods in 2016 primarily as a result of increased ADCETRIS net product sales. ADCETRIS net product sales increased from the comparable periods in 2016 primarily due to an increase in sales volume and, to a lesser extent, price increases. The increases in sales volumes in both periods were driven primarily by increased use of ADCETRIS across multiple lines of therapy in Hodgkin lymphoma and for the treatment of other malignancies.

In addition, as of December 31, 2017, Seattle Genetics had approximately $413 million in cash and cash equivalents and short-term investments.
