Kinnate Biopharma Inc. Reports First Quarter 2021 Financial Results and Announces FDA Clearance of Investigational New Drug Application for KIN-2787

KIN-2787 is the company’s RAF inhibitor candidate for patients with mutant BRAF-driven solid tumors

Planned initiation of Phase 1 clinical trial for KIN-2787 in mid-2021

Ended the quarter with cash and cash equivalents and investments of $383.1 million

Closed $35 million Series A financing of Chinese joint venture in May 2021

SAN FRANCISCO and SAN DIEGO, CA, USA I May 17, 2021 I 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 that the U.S Food and Drug Administration (FDA) has cleared the company’s Investigational New Drug (IND) application for KIN-2787 and also announced financial results for the quarter ended March 31, 2021. Kinnate expects to initiate a first-in-human Phase 1 clinical trial of KIN-2787 in patients with mutant BRAF-driven solid tumors in mid-2021.

“In the three years since our founding, Kinnate has consistently hit key milestones essential to our mission of delivering new therapies to patients with difficult-to-treat, genomically-defined cancers. The FDA's clearance of our KIN-2787 IND marks another major achievement for the company and demonstrates the important progress we are making in our transition to becoming a clinical-stage company,” said Nima Farzan, Chief Executive Officer of Kinnate. "As we prepare for our first-in-human trial of KIN-2787 later this year, we are also pleased with the rapid advance of our lead FGFR inhibitor candidate, KIN-3248, which we believe may offer a new option for certain patients with cancers like urothelial tumors or intrahepatic cholangiocarcinoma. We anticipate a first half of 2022 IND filing for KIN-3248."

The Phase 1 trial will evaluate the safety, tolerability, pharmacokinetics and anti-cancer activity of KIN-2787 in cancer patients with mutant BRAF-driven solid tumors.  The dose escalation portion (Part A) of the trial will determine the recommended dose and schedule of KIN-2787 for further evaluation in patients with BRAF mutations.  The dose expansion phase (Part B) of the trial will assess the safety and efficacy of KIN-2787 at the recommended dose and schedule in patients with cancers driven by BRAF Class II or III mutations, including lung cancer, melanoma and other selected adult solid tumors.

Recent Business Highlights and Corporate Update:

  • In our RAF program, we filed an IND in April 2021 with the FDA to study KIN-2787 in patients with mutant BRAF-driven solid tumors. The FDA cleared the IND in May 2021 and we anticipate initiating a Phase 1 clinical trial for KIN-2787 in mid-2021.  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 May 2021 we closed a $35 million Series A financing of a joint venture in China. Established with OrbiMed Asia Partners, OrbiMed Private Investments and Foresite Capital, the joint venture will be headquartered in Shanghai and the financing will enable the potential development and commercialization by the joint venture of certain Kinnate targeted oncology product candidates across Greater China (mainland China, Hong Kong, Taiwan, and Macau). Kinnate Biopharma will be the majority shareholder in the joint venture. The company has also announced that veteran biopharmaceutical industry executive Wenn Sun, Ph.D., has been appointed as the joint venture’s Executive Chair.
  • Data from pre-clinical studies of KIN-2787 have been selected for poster presentation at the 2021 American Society of Clinical Oncology (ASCO) Annual Meeting, which will be held virtually June 4-8, 2021. The data to be presented at the ASCO annual meeting was derived from pre-clinical studies evaluating the efficacy and tolerability of KIN-2787 in vitro and in vivo in BRAF mutation-driven human cancer models.
  • In our FGFR program, we selected KIN-3248 as our lead FGFR inhibitor candidate for the treatment of intrahepatic cholangiocarcinoma and urothelial carcinoma and initiated GLP-toxicity studies of KIN-3248.  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 and, subject to our planned IND submission taking effect, initiating a Phase 1 clinical trial for KIN-3248 in the first half of 2022.
  • We 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.
  • We expanded our organization to 41 full-time employees at March 31, 2021, of which 30 were engaged in research and development activities.
