-Calithera to Provide Corporate Update via Conference Call and Webcast at 1:30 p.m. PT on March 7, 2019
SOUTH SAN FRANCISCO, Calif., March 07, 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 fourth quarter and year ended December 31, 2018. As of December 31, 2018, cash, cash equivalents and investments totaled $136.2 million.
“This is a time of significant progress for Calithera’s clinical development program as we continue to advance our novel onco-metabolism clinical candidates through robust clinical studies,” said Susan M. Molineaux, PhD, president and chief executive officer of Calithera. “In the fourth quarter, we broadened development of the novel glutaminase inhibitor telaglenastat through two new clinical trial collaborations with Pfizer. We recently completed enrollment of the ENTRATA trial of telaglenastat for the treatment of patients with renal cell carcinoma. We anticipate that this momentum will continue in 2019 with data from the ENTRATA trial and, with our partner Incyte, data from the INCB001158 program, both expected in the second half of the year.”
Fourth Quarter 2018 and Recent Highlights
- Completed patient enrollment in the randomized phase 2 ENTRATA trial of telaglenastat (CB-839) and everolimus in renal cell carcinoma (RCC). The ENTRATA trial (NCT03163667) is 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 a VEGFR-targeted tyrosine kinase inhibitor. The trial enrolled 69 patients at multiple centers in the United States. The primary endpoint of ENTRATA is progression-free survival (PFS). Calithera plans to report efficacy and safety data from the trial in the second half of 2019.
- Announced two new 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 Calithera’s glutaminase inhibitor telaglenastat. Preclinical data suggest that telaglenastat synergizes with PARP inhibitors to impair DNA synthesis, enhance DNA damage, and block cancer cell proliferation. Calithera will initiate a Phase 1/2 clinical trial of the combination of telaglenastat plus talazoparib in patients with RCC and TNBC in the first quarter of 2019. Telaglenastat also synergizes with CDK4/6 inhibitors by enhancing cell cycle arrest and blocking cancer cell proliferation. Calithera will initiate a Phase 1/2 clinical trial of the combination of telaglenastat plus palbociclib in patients with KRAS-mutated colorectal cancer (CRC) and patients with KRAS-mutated non-small cell lung cancer (NSCLC) in the second quarter of 2019.
- 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 the INCB001158 program are expected to be presented at a medical meeting in the second half of 2019.
- Initiated Phase 1 trial of arginase inhibitor CB-280 for the treatment of cystic fibrosis. 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. CB-280 is an orally administered small molecule inhibitor of arginase. The first-in-human Phase 1 trial initiated in February 2019 will evaluate the safety, tolerability and pharmacokinetic profile of oral CB-280 in healthy volunteers. The study will be conducted under a United States Food and Drug Administration (FDA) Investigational New Drug (IND) application.
- Initiated IND-enabling studies with CB-708, an oral small molecule CD73 inhibitor. The immuno-oncology target CD73 is an enzyme that plays a critical role in the process of ATP conversion to adenosine. Initiation of a Phase 1 study of CB-708, an orally administered small molecule inhibitor of CD73, is planned for 2019. A preclinical abstract describing CB-708 has been accepted for presentation at the 2019 American Association for Cancer Research annual meeting in March.
Selected Fourth Quarter 2018 Financial Results
Cash, cash equivalents and investments totaled $136.2 million at December 31, 2018.
Collaboration revenue for the full year 2018 was $22.2 million, compared with $26.0 million in the prior year. In June 2018, we completed the manufacturing services and technology transfer under our collaboration and license agreement with Incyte, which satisfied the performance obligation under ASC 606, and as a result, all remaining deferred revenue was recognized.
Research and development expenses for the full year 2018 were $66.2 million, compared with $43.1 million in the prior year. The increase of $23.1 million was due to an increase in the telaglenastat program to support our new and ongoing clinical trials, including for our Phase 2 CANTATA trial which opened in 2018, increases in the INCB001158 and CB-280 programs, as well as investment in early stage research. Research and development expenses for the fourth quarter of 2018 were $17.0 million, compared to $15.5 million for the same period last year.
General and administrative expenses for the full year 2018 were $13.3 million, compared with $12.5 million in the prior year. The increase of $0.8 million in 2018 was primarily due to higher personnel-related costs to support our clinical trials, offset partially by lower outside professional services, including activities related to our Incyte collaboration and license agreement and sublease in 2017. General and administrative expenses for the fourth quarter of 2018 were $3.2 million, compared to $3.3 million for the same period last year.
Interest Income, net for the full year 2018 was $2.7 million, compared with $1.9 million in the prior year. The increase of $0.8 million related to higher returns on our investments, partially offset by lower cash equivalents and investment balances. Interest income, net for the fourth quarter of 2018 was $0.7 million, compared to $0.6 million for the same period last year.
Net loss from operations for the three months and year ended December 31, 2018 was $19.5 million and $54.6 million, respectively.
