— Clinical study explored Calithera’s lead compound in combination with cabozantinib in patients with advanced renal cell carcinoma –
SOUTH SAN FRANCISCO, Calif., Feb. 16, 2019 (GLOBE NEWSWIRE) — Calithera Biosciences, Inc. (Nasdaq: CALA), a clinical stage biotechnology company focused on discovering and developing novel small molecule drugs directed against tumor metabolism and tumor immunology targets for the treatment of cancer, today announced that updated data from a Phase 1 study of the glutaminase inhibitor telaglenastat in combination with cabozantinib in patients with advanced renal cell carcinoma (RCC) will be presented at the American Society of Clinical Oncology Genitourinary Cancer (ASCO GU) Symposium, in San Francisco, California.
“Despite the advances in the treatment of renal cell carcinoma, there remains a significant unmet need among patients with advanced disease,” said Susan Molineaux, PhD, President and Chief Executive Officer of Calithera. “Based on promising Phase 1 results, we initiated and are currently enrolling the global, randomized CANTATA trial of telaglenastat plus cabozantinib with the hope of identifying a new therapeutic option that could benefit patients following their initial therapies.”
Telaglenastat is an investigational, novel glutaminase inhibitor specifically designed to block glutamine consumption in tumor cells. RCC tumors commonly exhibit metabolic alterations that increase their dependence on glutamine. In preclinical studies, telaglenastat produced synergistic antitumor effects when used in combination with standard-of-care RCC therapies including cabozantinib.
At the ASCO GU Symposium, Dr. Funda Meric-Bernstam from MD Anderson Cancer Center will present results from the Phase 1 study in an oral presentation (Abstract 549, Rapid Abstract Session C; RCC, Saturday February 16, 11:35 a.m. – 12:30 p.m. PST) and poster presentation, “CB-839, a glutaminase inhibitor, in combination with cabozantinib in patients with clear cell and papillary metastatic renal cell cancer: Results of a phase I study.” As of December 24, 2018, 12 advanced renal cell carcinoma patients were treated with telaglenastat plus cabozantinib and evaluable for response, including 10 clear cell patients, and two papillary patients. One hundred percent of evaluable patients experienced tumor shrinkage and disease control; this includes five patients who had a partial response and seven patients who had stable disease. In the clear cell patient population, the disease control rate was 100 percent and the response rate was 50 percent. Patients enrolled in the trial had advanced or metastatic disease and had received a median of three prior treatments, which included tyrosine kinase inhibitors, mTOR inhibitors, and checkpoint inhibitors. Patients were administered telaglenastat in oral doses that ranged from 600-800 mg twice a day in combination with a fixed oral dose of cabozantinib at 60 mg once a day.
In addition, Dr. Nizar Tannir from MD Anderson Cancer Center will present a poster describing the CANTATA trial at ASCO GU (Trials in Progress Poster Session C, Board K13). CANTATA is a global, randomized, double-blind trial designed to evaluate the safety and efficacy of telaglenastat in combination with cabozantinib versus placebo with cabozantinib in patients with advanced clear cell RCC who have been treated with one or two prior lines of systemic therapy. The trial will enroll approximately 400 patients and is designed with registrational intent. The primary endpoint is progression free survival by blinded independent review, and a key secondary endpoint is overall survival.

focused on developing products for patients with disorders of the ear,
nose, and throat (“ENT”). Novus has two technologies, each that has the
potential to be developed for multiple ENT indications. Novus’ lead
product candidate (OP0201) is a surfactant-based, drug-device
combination product being developed as a potential first-in-class
treatment option for patients at risk for, or with, otitis media (“OM”
or middle ear inflammation with or without infection). Globally, OM
affects more than 700 million adults and children every year, with over
half of the cases occurring in children under five years of age. OM is
one of the most common disorders seen in pediatric practice, and in the
United States is a leading cause of health care visits and the most
frequent reason children are prescribed antibiotics or undergo surgery.
Novus also has a foam-based drug delivery technology (OP0102), which may
be developed in the future to deliver drugs into the ear, nasal, and
sinus cavities. For more information please visit novustherapeutics.com.
