"We anticipate that 2020 will be an exciting year for Calithera, building on the substantial progress we made in 2019 and the potential for several significant clinical and regulatory milestones," said
2020 Milestones
Calithera expects to achieve the following milestones in 2020:
- Announce topline data from randomized CANTATA trial of telaglenastat with cabozantinib in advanced renal cell carcinoma (RCC). The 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 445 patients at multiple centers globally. The primary endpoint is progression-free survival. Calithera plans to report top-line efficacy and safety data from the trial in the second half of 2020.
- Initiate Phase 2 trial of telaglenastat in non-small cell lung cancer (NSCLC) patients with genetic mutation NRF2/KEAP1. The NRF2/KEAP1 pathway is known to drive the development of certain cancers, including a significant proportion of NSCLC through the regulation of reactive oxygen species in a manner that is dependent upon glutaminase activity. Recently presented clinical data demonstrate that activation of this pathway, either through the loss of KEAP1 function or activation of NRF2, results in very poor outcomes in NSCLC patients. The clear mechanistic rationale, strong preclinical data, and high unmet medical need in the NSCLC population have led Calithera to design a clinical study that will evaluate telaglenastat in combination with chemo-immunotherapy in first line NSCLC patients with tumors that harbor mutations in either KEAP1 or NRF2 that activate this pathway. This trial is expected to begin in the first half of 2020.
- Enroll telaglenastat (CB-839) combination trials in collaboration with Pfizer. Calithera and Pfizer have two clinical trial collaborations to evaluate Pfizer’s CDK4/6 inhibitor palbociclib, also known as IBRANCE®, and the dual-mechanism poly (ADP-ribose) polymerase (PARP) inhibitor talazoparib, also known as TALZENNA®, each in combination with glutaminase inhibitor telaglenastat.
- Continue enrollment of multiple clinical trials evaluating Calithera’s arginase inhibitor INCB001158. INCB001158 is a small-molecule immuno-oncology therapeutic being evaluated in multiple clinical trials as a single-agent and in combination with immunotherapies and chemotherapy for the treatment of patients with cancer. INCB001158 is being developed as part of a collaboration and license agreement with
Incyte . - Enroll clinical dose escalation trial evaluating CB-280, an oral arginase inhibitor, in cystic fibrosis (CF). Arginase is believed to be critical in the pathology of cystic fibrosis. It impairs production of nitric oxide and generates metabolites of arginine that may impair lung function. A Phase 1b clinical study in people with CF, which is expected to start enrollment in the first half of 2020, will test multiple doses of CB-280 compared to placebo in approximately 30 adults with CF to determine a safe dose range, and pharmacodynamics effects of arginase inhibition in this population. Patients with any CF transmembrane conductance regulator mutational status will be eligible for the study.
