SOUTH SAN FRANCISCO, Calif., Aug. 08, 2019 (GLOBE NEWSWIRE) -- Calithera Biosciences, Inc. (CALA), a clinical stage biotechnology company focused on discovering and developing novel small molecule drugs for the treatment of cancer and other life-threatening diseases, announced today its financial results for the second quarter ended June 30, 2019. As of June 30, 2019, cash equivalents and investments totaled $153.2 million.
“In the second quarter, we achieved clinical proof of concept for our glutaminase inhibitor telaglenastat, with positive topline results of the randomized phase 2 ENTRATA study,” said Susan Molineaux, PhD, president and chief executive officer of Calithera. “After completing a secondary offering in the quarter, we are well positioned to execute on our strategy and advance our pipeline forward. In the second half of the year, we look forward to completing enrollment in our registrational CANTATA trial evaluating telaglenastat for the treatment of patients with renal cell carcinoma, as well as presenting data from our arginase inhibitor program INCB001158.”
Second Quarter 2019 and Recent Highlights
Achieved positive topline results in randomized Phase 2 ENTRATA study of telaglenastat (CB-839) with everolimus in renal cell carcinoma. The ENTRATA trial (NCT03163667) was a Phase 2 randomized, double-blind trial designed to evaluate the safety and efficacy of telaglenastat in combination with everolimus versus placebo with everolimus in patients with advanced clear cell RCC who have been treated with at least two prior lines of systemic therapy, including at least one prior VEGFR-targeted tyrosine kinase inhibitor. The trial enrolled 69 patients at multiple centers in the United States. The primary endpoint of ENTRATA was progression-free survival (PFS). The combination doubled the median PFS in heavily pretreated patients with advanced RCC. Telaglenastat, when added to everolimus, doubled the median PFS to 3.8 months as compared to 1.9 months for everolimus alone and reduced the risk of disease progression or death by 36% (HR=0.64, p=0.079 one-sided). The primary endpoint of the trial was PFS per investigator assessment with a predetermined threshold of p≤0.2 one-sided. The secondary endpoint of overall survival is not yet mature.
Initiated Phase 1/2 clinical trial of telaglenastat in combination with palbociclib for solid tumors. The Phase 1/2 clinical trial is evaluating telaglenastat in combination with Pfizer’s CDK4/6 inhibitor palbociclib, also known as Ibrance®. The study will evaluate the safety and anti-tumor activity of telaglenastat plus palbociclib in patients with KRAS-mutated colorectal cancer (CRC) and KRAS-mutated non-small cell lung cancer (NSCLC).
Advanced INCB001158 arginase inhibitor immuno-oncology program. INCB001158 is being evaluated in multiple clinical trials for the treatment of patients with cancer both as a monotherapy, and in combination with immunotherapies and chemotherapy. INCB001158 is being developed as part of a collaboration and license agreement with Incyte. Data from INCB001158 are expected to be presented at the European Society for Medical Oncology (ESMO) Congress in September.
Presented new preclinical data for CB-708 at AACR Annual Meeting. CB-708 is a selective, oral inhibitor of CD73, an enzyme that synthesizes the immunosuppressive agent adenosine and is over expressed in multiple tumor types. By blocking adenosine production in the tumor, CB-708 is designed to enhance T-cell activation leading to anti-tumor activity. Calithera anticipates that CB-708 will enter clinical trials in the second half of 2019.
Completed public offering of common stock. In June 2019, Calithera completed an underwritten public offering of common stock. Gross proceeds from the offering, before underwriting discounts and commissions and offering expenses, were $57.5 million.
Selected Second Quarter 2019 Financial Results
Cash, cash equivalents and investments totaled $153.2 million at June 30, 2019.
Research and development expenses were $20.9 million for the three months ended June 30, 2019, compared with $17.3 million for the same period in the prior year. The increase of $3.6 million was primarily due to a $1.5 million increase in the telaglenastat program, including for the CANTATA trial, an increase of $1.5 million in the INCB001158 program, and an increase of $0.7 million in the CB-280 program, partially offset by a decrease of $0.1 million for investment in our early stage research programs.
General and administrative expenses were $4.0 million for the three months ended June 30, 2019, compared with $3.5 million for the same period in the prior year. The increase of $0.5 million was related to higher professional services costs.
Net loss for the three months ended June 30, 2019 was $24.2 million, or $0.58 per share.
