“The company continues to make meaningful progress with our pipeline candidates, inclusive of our pan-RAF inhibitor, KIN-2787, and our FGFR inhibitor, KIN-3248, both in the clinic, and with initial data from the Phase 1 KN-8701 clinical trial forthcoming later this year for KIN-2787,” said Nima Farzan, Chief Executive Officer of Kinnate. “We remain focused on developing a new generation of small molecule kinase inhibitors that target a wide range of cancers, including those that resist current treatment, and we are incredibly proud that in just four years we have advanced two compounds into clinical trials, with several more compounds in the pipeline. Our consistent, disciplined use of capital and updated cash runway guidance is expected to enable Kinnate to fund scientific innovation and operations into early 2024.”

Recent Business Highlights and Corporate Update:         

KIN-2787, pan-RAF inhibitor

• Initial monotherapy data from the ongoing Phase 1 KN-8701 clinical trial expected in the fourth quarter of 2022.
• Upon meeting a combination of pre-specified milestones in the ongoing Phase 1 KN-8701 clinical trial, initiated combination portion of KN-8701 to study KIN-2787 with binimetinib in NRAS-mutant melanoma; initial data expected in the first half of 2023.
• Abstract highlighting the company's KIN-2787 program was accepted for publication at the American Society of Clinical Oncology (“ASCO”) Annual Meeting taking place June 3-7, 2022, in Chicago, Illinois. The abstract is titled: Antitumor activity of KIN-2787, a next-generation pan-RAF inhibitor, in combination with MEK inhibition in preclinical models of human NRAS mutant melanoma.
• Presented three separate poster presentations highlighting (1) preclinical activity of KIN-2787 in BRAF alteration positive and NRAS-mutant melanoma models, (2) an overview of the KN-8701 clinical trial design and (3) a clinico-genomics study and outcome analysis that documented the common occurrence of BRAF Class II and Class III alterations across solid tumors, at the 2022 American Association for Cancer Research (AACR) Annual Meeting.

KIN-3248, FGFR Inhibitor

• Abstract highlighting KIN-3248 was accepted for poster presentation during the ASCO 2022 Annual Meeting. The abstract is titled: Design and rationale of a first-in-human (FIH) phase 1/1b study evaluating KIN-3248, a next-generation, irreversible (irrev), pan-FGFR inhibitor (FGFRi), in adult patients with solid tumors harboring FGFR2 and/or FGFR3 gene alterations (NCT05242822).
• Announced that the first patient has commenced treatment in KN-4802 (NCT05242822), a Phase 1 clinical trial evaluating KIN-3248. KIN-3248 is a next-generation pan-FGFR inhibitor being developed for the treatment of intrahepatic cholangiocarcinoma (ICC) and urothelial carcinoma (UC), as well as other solid tumors. KN-4802 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.
