Kineta, Inc. (Nasdaq: KA) announced today that the first patient has been dosed in Part B of its Phase 1/2 VISTA-101 clinical trial that will evaluate the safety and tolerability of the company’s VISTA blocking immunotherapy, KVA12123, in combination with Merck’s anti-PD-1 therapy KEYTRUDA® (pembrolizumab) in patients with advanced solid tumors.
The Combination Arm (Part B) of the Phase 1/2 Clinical Trial Builds Upon the Initial Safety, Tolerability and Pharmacokinetic Data of KVA12123 in the Monotherapy Arm (Part A)
Initial Combination Therapy Clinical Data Anticipated in Q2 2024
SEATTLE, Oct. 17, 2023 (GLOBE NEWSWIRE) -- Kineta, Inc. (Nasdaq: KA), a clinical-stage biotechnology company focused on the development of novel immunotherapies in oncology that address cancer immune resistance, announced today that the first patient has been dosed in Part B of its Phase 1/2 VISTA-101 clinical trial that will evaluate the safety and tolerability of the company’s VISTA blocking immunotherapy, KVA12123, in combination with Merck’s anti-PD-1 therapy KEYTRUDA® (pembrolizumab) in patients with advanced solid tumors.
“Dosing the first patient in the combination arm with KEYTRUDA and KVA12123 is a significant milestone for Kineta, and we are very pleased with the progress of our differentiated VISTA blocking immunotherapy,” said Shawn Iadonato, Ph.D., Chief Executive Officer of Kineta. “We anticipate that the results from the combination arm will further build on the already encouraging initial safety, tolerability, and pharmacokinetic profile of KVA12123 observed in the monotherapy arm. We look forward to reporting initial clinical data for the combination treatment next year.”
The Phase 1/2 clinical study (NCT05708950) is designed to evaluate the safety, tolerability, pharmacokinetics, immunogenicity, and tumor response of KVA12123 alone and in combination with pembrolizumab in patients with advanced solid tumors. The study will be conducted in 4 parts. The Phase 1 study (Parts A and B) will focus on dose escalation of KVA12123 as a monotherapy and in combination with pembrolizumab which has now been initiated. Additionally, Parts A and B will be used to determine a recommended Phase 2 dose (RP2D) for Parts C and D. The clinical trial will transition into a Phase 2 study (Parts C and D) that will focus on dose expansion with an optimized dose.
KVA12123 is a VISTA blocking immunotherapy in development as a twice weekly infusion. The drug is being evaluated in a Phase 1/2 clinical trial for patients with advanced solid tumors. Competitive therapies targeting VISTA have demonstrated either poor monotherapy anti-tumor activity in preclinical models or induction of cytokine release syndrome (CRS) in human clinical trials. Through the combination of unique epitope binding and an optimized IgG1 Fc region, KVA12123 demonstrates strong monotherapy tumor growth inhibition in preclinical models without evidence of CRS in clinical trial participants. KVA12123 effectively de-risks the VISTA target and provides a novel approach to address immune suppression in the tumor microenvironment (TME) with a mechanism of action that is differentiated and complementary to T cell focused therapies. KVA12123 may be an effective immunotherapy for many types of cancer including non-small cell lung (NSCLC), colorectal, renal cell carcinoma, head and neck, and ovarian cancer.
Initial combination therapy clinical data as well as additional monotherapy safety and efficacy data are expected in Q2 2024.

About Kineta
Kineta (Nasdaq: KA) is a clinical-stage biotechnology company with a mission to develop next-generation immunotherapies that transform patients’ lives. Kineta has leveraged its expertise in innate immunity and is focused on discovering and developing potentially differentiated immunotherapies that address the major challenges with current cancer therapy. The company’s immuno-oncology pipeline includes KVA12123, a novel VISTA blocking immunotherapy currently in a Phase 1/2 clinical trial in patients with advanced solid tumors, and a preclinical monoclonal antibody targeting CD27.

VISTA (V-domain Ig suppressor of T cell activation) is a negative immune checkpoint that suppresses T cell function in a variety of solid tumors. High VISTA expression in tumor correlates with poor survival in cancer patients and has been associated with a lack of response to other immune checkpoint inhibitors. Blocking VISTA induces an efficient polyfunctional immune response to address immunosuppression and drives anti-tumor responses.
