Kineta Announces Completion of Enrollment in the Monotherapy Arm of the VISTA-101 Phase 1 Clinical Study in Advanced Solid Tumors

Kineta has completed enrollment in the monotherapy cohorts of the Phase 1 VISTA-101 clinical trial.

The ongoing Phase 1 study is now enrolling patients into cohorts evaluating KVA12123 in combination with Merck's anti-PD-1 therapy, KEYTRUDA^® (pembrolizumab).

The company will present additional scientific data in 2024 at an upcoming scientific meeting.

SEATTLE, Oct. 08, 2024 (GLOBE NEWSWIRE) -- Kineta, Inc. (OTC:KANT) ("Kineta" or the "Company"), a clinical-stage biotechnology company focused on the development of novel immunotherapies in oncology that address cancer immune resistance, announced today that it has completed the enrollment of new patients into the monotherapy arm of the VISTA-101 phase 1 clinical trial evaluating KVA12123, Kineta's novel VISTA blocking immunotherapy, in patients with advanced solid tumors. The monotherapy portion of the trial enrolled patients in 6-dose cohorts ranging from 3mg to 1000mg every two weeks and no dose limiting toxicities or cytokine related adverse events have been observed in the study. The Company is continuing to enroll patients into cohorts evaluating KVA12123 in combination with Merck's (known as MSD outside of the US and Canada) anti-PD-1 therapy, KEYTRUDA^® (pembrolizumab).

Initial results demonstrating partial response and stable disease in the cohorts evaluating KVA12123 in combination with pembrolizumab and durable stable disease in the monotherapy cohorts were reported earlier this year at the American Association of Cancer Research (AACR) Annual Meeting 2024. Additionally, the initial results of KVA12123 showed a favorable clinical safety and tolerability profile with no dose limiting toxicities and no evidence of CRS-associated cytokines at any dose level. "We are pleased to successfully complete patient enrollment in the monotherapy arm, and we remain on target for completing full enrollment into this study before year end," said Craig W. Philips, President of Kineta.

On July 8, 2024, Kineta announced that it had entered into an exclusivity and right of first offer agreement (the "Agreement") with TuHURA Biosciences, Inc. ("TuHURA"), a Phase 3 registration-stage immuno-oncology company developing novel technologies to overcome resistance to cancer immunotherapy. As part of the Agreement, Kineta received a $5 million nonrefundable payment from TuHURA in July 2024. In August 2024, Kineta announced that in collaboration with TuHURA, it reopened enrollment in the VISTA-101 clinical trial. Kineta and TuHURA continue to collaborate on the ongoing Phase 1 clinical program in patients with advanced solid tumor cancer. On October 2, 2024, Kineta announced that TuHURA was exercising its right to extend their exclusivity and right of first offer pursuant to the terms of the Agreement.

KEYTRUDA^® is a registered trademark of Merck Sharp & Dohme LLC, a subsidiary of Merck & Co., Inc., Rahway, NJ, USA.

About Kineta

Kineta 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.

Through the combination of unique epitope binding and an optimized IgG1 Fc region, KVA12123 has demonstrated strong tumor growth inhibition as both a monotherapy and in combination with other checkpoint inhibitors in preclinical models. KVA12123 provides a novel approach to address immune suppression in the tumor microenvironment 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.

In February 2024, Kineta announced a significant corporate restructuring to substantially reduce expenses and preserve cash. The restructuring included a significant workforce reduction and the suspension of enrollment of new patients in its ongoing VISTA-101 Phase 1/2 clinical trial evaluating KVA12123 in patients with advanced solid tumors. At that time, Kineta also announced that it was exploring strategic alternatives to maximize stockholder value.
