KIN-004

Completed recent IPO, raising $276MM in gross proceeds to fund kinase inhibitors for genomically defined cancers Progress towards IND filing for KIN-2787, our RAF inhibitor candidate, in the first half of 2021 and initiating a Phase 1 clinical trial later in the year remains on track Selected KIN-3248 as our lead FGFR inhibitor candidate; anticipate IND filing in the first half of 2022 SAN FRANCISCO and SAN DIEGO, March 29, 2021 (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, 2020. “Since completing our IPO last year, we entered 2021 well-funded to advance the development of our lead targeted therapy RAF and FGFR programs towards the clinic,” said Nima Farzan, Chief Executive Officer of Kinnate Biopharma. “We are pleased to be on track with our stated goals of filing an investigational new drug application for KIN-2787, our RAF inhibitor candidate, in the first half of 2021 and initiating a Phase 1 clinical trial later in the year. Additionally, our FGFR inhibitor KIN-3248 candidate is progressing towards an IND filing and Phase I clinical trial in the first half of 2022. We believe our Kinnate drug discovery engine has the ability to identify product candidates with the potential to overcome the limitations of current targeted oncology therapeutics.” Recent Business Highlights and Corporate Update: In December 2020, completed a successful initial public offering, raising $276.0 million in aggregate gross proceeds (before deducting underwriting discounts and commissions and estimated offering expenses) and listed on The Nasdaq Global Select Market. Remain on track for an Investigational New Drug (IND) filing for KIN-2787 in the first half of 2021 following encouraging pre-IND feedback from the U.S. Food and Drug Administration (FDA). KIN-2787, our most advanced product candidate, is a RAF inhibitor we are developing for the treatment of patients with lung cancer, melanoma and other solid tumors. Unlike currently available treatments that target only Class I BRAF kinase mutations, we have designed KIN-2787 to target Class II and Class III BRAF mutations, where it would be a first-line targeted therapy, in addition to covering Class I BRAF mutations. In our KIN003 program we have selected KIN-3248 as our lead FGFR inhibitor candidate for the treatment of patients with intrahepatic cholangiocarcinoma and urothelial carcinoma. Our FGFR candidates are designed to address clinically observed genomic alterations in FGFR2 and FGFR3 that drive resistance to current therapies. We anticipate filing an IND for KIN-3248 with the FDA in the first half of 2022. Our RAF and FGFR candidates have demonstrated proof of concept in preclinical models and, subject to our planned IND submissions taking effect, we anticipate initiating a Phase 1 clinical trial for KIN-2787 in 2021 and an additional Phase 1 clinical trial for KIN-3248 in the first half of 2022. Continued to advance a number of other small molecule research programs, including a CDK12 inhibitor in our KIN004 program to target the treatment of ovarian carcinoma, triple-negative breast cancer and metastatic castration-resistant prostate cancer. Expanded organization with 31 full-time employees at December 31, 2020, of which 24 were engaged in research and development activities.
