Partial response and stable disease reported in combination cohort, and durable stable disease observed in monotherapy cohorts
No dose limiting toxicities observed at any dose level
Cleared fifth of six monotherapy cohorts and second of four combination cohorts
Kineta is actively exploring strategic alternatives to maximize value for all stakeholders
SEATTLE, March 12, 2024 (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 an update on its ongoing VISTA-101 Phase 1/2 clinical trial evaluating KVA12123 as monotherapy and in combination with Merck’s anti-PD therapy, KEYTRUDA® (pembrolizumab) in patients with advanced solid tumors. KVA12123 cleared the fifth of six monotherapy dose levels and the second of four cohorts in combination with pembrolizumab. KVA12123 was well tolerated with no dose limiting toxicities (DLT) or cytokine related adverse events at any dose level.
Monotherapy Dose Escalation (3 – 300 mg KVA12123 Q2W)
Combination Therapy Dose Escalation (30-100 mg KVA12123 Q2W, 400 mg pembrolizumab Q6W)
Biomarkers
Safety
“We are pleased with the progress of the study, the initial clinical response data, and the durability of patient benefit emerging from the study. We continue to be encouraged by the safety profile of KVA12123, supporting advancement to higher doses,” said Thierry Guillaudeux, Ph.D., Chief Scientific Officer of Kineta. “KVA12123 has a best-in-class potential that may offer patients a novel approach to address immunosuppression in the tumor microenvironment to better manage solid tumor cancers.”
The Company recently announced its restructuring and that it is pursuing strategic alternatives to maximize shareholder value due to certain investors indicating they will not fulfill their April 2024 funding obligation in a private placement financing. As a result, the Company has suspended new patient enrollment into the Phase 1/2 VISTA-101 trial and will not be recruiting patients into either the sixth cohort in the monotherapy arm or the third cohort in the combination therapy arm. Patients currently enrolled in the trial will be permitted to continue to participate.
KEYTRUDA® is a registered trademark of Merck Sharp & Dohme LLC, a subsidiary of Merck & Co., Inc., Rahway, NJ, USA.
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. For more information on Kineta, please visit www.kinetabio.com, and follow Kineta on X (Twitter) and LinkedIn.
KVA12123 is a VISTA blocking immunotherapy in development as a twice weekly monoclonal antibody infusion drug 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 has been shown to de-risk the VISTA target and provides a novel approach to address immune suppression in the TME with a mechanism of action that is differentiated and complementary with 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.
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.
