SAN FRANCISCO and SAN DIEGO, May 11, 2023 (GLOBE NEWSWIRE) -- Kinnate Biopharma Inc. (NASDAQ:KNTE) ("Kinnate"), a clinical-stage precision oncology company, today announced financial results for the first quarter of 2023 and recent corporate updates.

"Kinnate continues to make demonstrable progress with its pipeline of highly selective compounds designed with optimized drug properties and the ability to address a broad set of alterations, overcome resistance mechanisms and/or achieve brain penetrance," said Nima Farzan, chief executive officer, Kinnate Biopharma Inc. "At AACR this year, we presented the first clinical data for the company from our RAF program, showing exarafenib, the lead product candidate, was well-tolerated, achieved substantial, dose proportional and therapeutically meaningful exposures with objective measures of response supporting its best-in-class profile. Building on this momentum, we look forward to several additional catalysts in the second half of the year, including dose selection for the exarafenib and binimetinib combination where we've also observed early responses, initial dose escalation data for KIN-3248, our investigational pan-FGFR inhibitor, and entering the clinic with our third internally developed product candidate, a brain-penetrant MEK inhibitor. With a strong balance sheet, we believe our current capital will fund operations into early 2025, enabling our continued growth as a global company."

Pipeline Updates

• The company will have a poster presentation at the 2023 American Society of Clinical Oncology Annual Meeting on circulating tumor DNA-based genomic landscape analysis to evaluate molecular brake and gatekeeper mutations in FGFR2. (View Poster Details) Initial dose escalation data from the ongoing global Phase 1 clinical trial, KN-4802, evaluating the pan-FGFR inhibitor, KIN-3248, in patients with FGFR2/3 alterations is expected in the second half of 2023.
• Presented exarafenib monotherapy dose escalation data from KN-8701, a global Phase 1 clinical trial, during an oral presentation at the American Association for Cancer Research (AACR) 2023 Annual Meeting. In addition, the company provided an update on the monotherapy dose expansion strategy and announced preliminary findings from the combination arm of KN-8701, evaluating exarafenib plus binimetinib. The company expects to provide an update in the second half of 2023 on the dose selection and additional escalation data for exarafenib plus binimetinib, and initial exarafenib monotherapy dose expansion data in the first half of 2024.

• Presented preclinical data for exarafenib monotherapy and in combination with a MEK inhibitor in human NRAS mutant melanoma models in a poster session at the AACR 2023 Annual Meeting. (View Poster)
• Announced the addition of two next-generation development candidates to the pipeline – a brain penetrant mitogen-activated protein kinase (MEK) inhibitor (KIN-7136), expected to enter the clinic in the second half of 2023, and a highly selective mesenchymal epithelial transition (c-MET) inhibitor (KIN-8741), expected to enter the clinic in the first half of 2024.
