Calithera Biosciences Reports Second Quarter 2020 Financial Results and Recent Highlights
--Calithera to Provide Corporate Update via Conference Call and Webcast at 2:00 p.m. PT on August 10, 2020--
SOUTH SAN FRANCISCO, Calif., Aug. 10, 2020 (GLOBE NEWSWIRE) -- Calithera Biosciences, Inc. (Nasdaq: 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, 2020.
“We continued our positive momentum from 2019 into the first half of 2020, further strengthening our cash position and advancing our key clinical development programs,” said Susan Molineaux, PhD, president and chief executive officer of Calithera. “Recently, we announced the initiation of the first clinical trial to evaluate our novel arginase inhibitor in cystic fibrosis, and we have also made significant progress toward the initiation of our first clinical trial evaluating telaglenastat in people with non-small cell lung cancer whose tumors have KEAP1 or NRF2 genetic mutations. We look forward to top-line results from our pivotal CANTATA trial in renal cell carcinoma in late fourth quarter of 2020 or early first quarter 2021.”
Second Quarter 2020 and Other Recent Program Highlights
- CANTATA randomized trial of telaglenastat and cabozantinib in advanced renal cell carcinoma (RCC). The pivotal CANTATA trial is a global, randomized, double-blind clinical trial of telaglenastat combined with cabozantinib, in patients with advanced or metastatic RCC who have received one or two prior treatments. The CANTATA trial enrolled 444 patients at multiple centers globally. The primary endpoint is progression-free survival (PFS). In light of delays associated with COVID-19, and pending further developments in the ongoing pandemic, Calithera expects to report top-line efficacy and safety data from the trial in late fourth quarter of 2020 or early first quarter 2021.
- KEAPSAKE randomized trial in non-small cell lung cancer (NSCLC) patients with a KEAP1 or NRF2 genetic mutation. Mutations in the KEAP1/NRF2 pathway, which occur in an estimated 20 percent of NSCLC patients, are associated with aggressive tumor growth. Recently presented clinical data demonstrate that activation of this pathway, either through the loss of KEAP1 function or activation of NRF2, are associated with poor clinical outcomes among patients with NSCLC receiving front-line standard-of-care chemoimmunotherapy. Pre-clinical models have shown that activation of the KEAP1/NRF2 pathway makes tumors dependent on glutaminase activity for growth and survival, making these tumors exquisitely sensitive to inhibition of glutaminase activity by telaglenastat. The double-blind telaglenastat trial, which is open for enrollment, will enroll approximately 120 patients with stage IV non-squamous NSCLC with tumors that have the KEAP1 or NRF2 mutation. Patients will be randomized to receive telaglenastat or placebo, in combination with pembrolizumab, carboplatin and pemetrexed. The study will evaluate the safety and investigator-assessed PFS of telaglenastat plus these standard-of-care chemoimmunotherapies. Given the previously reported challenges associated with opening new clinical studies during the current stage of the COVID-19 pandemic, Calithera expects to enroll the first patient in the third quarter of 2020, pending further developments in the COVID-19 situation. Calithera plans to present interim data from this trial in 2021.
- Pfizer clinical collaboration with the CDK4/6 inhibitor IBRANCE®, and the dual-mechanism poly (ADP-ribose) polymerase (PARP) inhibitor TALZENNA®, each in combination with telaglenastat. In March 2019, Calithera initiated a Phase 1/2 trial of the combination of telaglenastat plus Talzenna in patients with solid tumors including expansion cohorts in RCC and triple-negative breast cancer. Dose escalation has been successfully completed. Following preliminary dose expansion, the company is no longer developing this combination. In July 2019, the company initiated a Phase 1/2 trial of the combination of telaglenastat plus Ibrance in patients with solid tumors including expansion cohorts in KRAS-mutated colorectal cancer and KRAS-mutated non-small cell lung cancer. Dose escalation has been completed and dose expansion cohorts are enrolling following a temporary pause due to the COVID-19 situation.
- CB-280 arginase inhibitor program. In July 2020, Calithera initiated a Phase 1b clinical trial in adult patients with cystic fibrosis and chronic airway infection. The randomized, double blind, placebo-controlled, dose escalation trial will evaluate multiple ascending doses of CB-280, dosed orally twice daily for 14 days, compared to placebo in up to 32 adult CF patients to determine a safe dose range for CB-280. The study follows the completion of a Phase 1 trial that evaluated the safety, tolerability and pharmacokinetic profile of CB-280 in healthy volunteers.
- INCB001158 program. INCB001158, an internally discovered molecule, is being evaluated in multiple clinical trials for the treatment of patients with solid tumors both as a monotherapy, in combination with anti-PD-1 immunotherapy, and in multiple chemotherapy regimens. INCB001158 is being developed as part of a collaboration and license agreement with Incyte.
