SAN FRANCISCO and SAN DIEGO, March 28, 2022 (GLOBE NEWSWIRE) -- Kinnate Biopharma Inc. (NASDAQ:KNTE) ("Kinnate"), a biopharmaceutical company focused on the discovery and development of small molecule kinase inhibitors for difficult-to-treat, genomically defined cancers, today announced financial results for the full year ended December 31, 2021.

"The continuing advancement across our pipeline last year, including the first patient being dosed in our Phase 1 trial evaluating KIN-2787 in adult patients with BRAF-mutant advanced and metastatic tumors, positions the company to further deliver on several key upcoming milestones in 2022," said Nima Farzan, Chief Executive Officer of Kinnate Biopharma. "For KIN-2787, we are on target to report initial monotherapy data from the ongoing KN-8701 Phase 1 trial expected in the third quarter of 2022 and initial data from the combination of KIN-2787 with binimetinib in NRAS-mutant melanoma by year end 2022. Beyond KIN-2787, we were pleased to receive IND clearance for KIN-3248, a next-generation pan-FGFR inhibitor, from the FDA earlier this year and initiated the Phase 1 trial in the first quarter. Our goal of generating one IND filing per year from our Kinnate Discovery Engine remains an important focus for the company as we look to improve upon current targeted oncology outcomes."

Recent Business Highlights and Corporate Update:

KIN-2787, pan-RAF inhibitor

• Announced that three abstracts highlighting data from KIN-2787 have been accepted for presentation at the upcoming American Association for Cancer Research (AACR) Annual Meeting 2022, to be held April 8-13, in New Orleans, Louisiana. KIN-2787 is an orally available small molecule pan-RAF inhibitor being developed for the treatment of patients with lung cancer, melanoma, and other solid tumors. The three abstracts include:
  • Occurrence of BRAF class II and III alterations is common across solid tumors and is associated with inferior clinical outcomes in NSCLC and melanoma (PAN# 4122);
  • Design and rationale of a first in human (FIH) Phase 1/1b study evaluating KIN-2787, a potent and highly selective pan-RAF inhibitor, in adult patients with BRAF- and NRAS-mutation positive solid tumors (PAN# CT248); and
  • Antitumor activity of KIN-2787, a next-generation pan-RAF inhibitor, in preclinical models of human RAF/RAS mutant melanoma (PAN# 2674).
• Presented findings from a collaborative study with Tempus investigating the prevalence of Class II and Class III alterations among patients with BRAF-mutated solid tumors. These findings were presented as an e-Poster at the virtual European Society for Medical Oncology (ESMO) Targeted Anticancer Therapies Congress (TAT). The meeting took place March 7-9, 2022.
• Delivered an oral presentation of KIN-2787 preclinical data at the virtual IASLC 2022 Targeted Therapies of Lung Cancer meeting which took place February 22-26, 2022. In this study, KIN-2787 activity was assessed by suppression of downstream MAPK pathway signaling and subsequent cell growth inhibition across BRAF-altered and/or RAS-altered versus wild type panels of human non-small cell lung cancer (NSCLC) cell lines.

KIN-3248, FGFR Inhibitor

• Announced the presentation of updates from preclinical studies evaluating its Fibroblast Growth Factor Receptor (FGFR) inhibitor candidate, KIN-3248, a next-generation pan-FGFR inhibitor being developed for intrahepatic cholangiocarcinoma (ICC) and urothelial carcinoma (UC) and other solid tumors. These findings were presented during a poster session at the ASCO Gastrointestinal Cancers Symposium which took place January 20-22, 2022.
• On January 18, 2022 announced that the U.S Food and Drug Administration (FDA) has cleared the company's Investigational New Drug (IND) application for KIN-3248. The Phase 1 trial initiated in the first quarter of 2022 and will evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and anti-cancer activity of KIN-3248 in FGFR inhibitor naïve and pretreated cancer patients with FGFR2 and/or FGFR3 gene alterations.

Full-Year 2021 Financial Results

• Full year net loss for 2021 was $89.8 million, compared to $35.8 million in 2020.
• Full year research and development expenses for 2021 were $67.2 million, compared to $29.2 million in 2020.
• Full year general and administrative expenses for 2021 increased to $22.9 million, compared to $6.8 million in 2020.
• As of December 31, 2021, the total of cash and cash equivalents and short-term investments was $324.9 million, exclusive of the joint venture's cash.
