A highly potent anti-VISTA antibody KVA12123 - a new immune checkpoint inhibitor and a promising therapy against poorly immunogenic tumors

Article

BackgroundImmune checkpoint therapies have led to significant breakthroughs in cancer patient treatment in recent years. However, their efficiency is variable, and resistance to immunotherapies is common. VISTA is an immune-suppressive checkpoint inhibitor of T cell response belonging to the B7 family and a promising novel therapeutic target. VISTA is expressed in the immuno-suppressive tumor microenvironment, primarily by myeloid lineage cells, and its genetic knockout or antibody blockade restores an efficient antitumor immune response.MethodsFully human monoclonal antibodies directed against VISTA were produced after immunizing humanized Trianni mice and sorting and sequencing natively-linked B cell scFv repertoires. Anti-VISTA antibodies were evaluated for specificity, cross-reactivity, monocyte and T cell activation, Fc-effector functions, and antitumor efficacy using in vitro and in vivo models to select the KVA12123 antibody lead candidate. The pharmacokinetics and safety profiles of KVA12123 were evaluated in cynomolgus monkeys.ResultsHere, we report the development of a clinical candidate anti-VISTA monoclonal antibody, KVA12123. KVA12123 showed high affinity binding to VISTA through a unique epitope distinct from other clinical-stage anti-VISTA monoclonal antibodies. This clinical candidate demonstrated high specificity against VISTA with no cross-reactivity detected against other members of the B7 family. KVA12123 blocked VISTA binding to its binding partners. KVA12123 induced T cell activation and demonstrated NK-mediated monocyte activation. KVA12123 treatment mediated strong single-agent antitumor activity in several syngeneic tumor models and showed enhanced efficacy in combination with anti-PD-1 treatment. This clinical candidate was engineered to improve its pharmacokinetic characteristics and reduce Fc-effector functions. It was well-tolerated in preclinical toxicology studies in cynomolgus monkeys, where hematology, clinical chemistry evaluations, and clinical observations revealed no indicators of toxicity. No cytokines associated with cytokine release syndrome were elevated.ConclusionThese results establish that KVA12123 is a promising drug candidate with a distinct but complementary mechanism of action of the first generation of immune checkpoint inhibitors. This antibody is currently evaluated alone and in combination with pembrolizumab in a Phase 1/2 open-label clinical trial in patients with advanced solid tumors.

Sensei nearly halves headcount to push through anti-VISTA antibody

Boston-based Sensei Biotherapeutics announced it will close its research facility in Rockville, Maryland, and also reduce its workforce by 46%, primarily affecting its preclinical R&D team.The move comes as Sensei looks to focus resources on advancing clinical development of its lead candidate, SNS-101, a conditionally active antibody targeting the VISTA immune checkpoint. The company expects its current cash balance to fund operations into the second quarter of 2026."We believe SNS-101 has disruptive potential for the treatment of a multitude of cancer indications," stated CEO John Celebi."The third quarter…saw significant progress in advancing patient enrollment in the dose expansion portion of the Phase I study for SNS-101 across dose levels and patients with primary and acquired resistance to PD-1 inhibitors. Looking ahead, management has focused its attention on preparing for Phase II studies."In May, Sensei reported an "encouraging" Phase I dataset for SNS-101, showing preliminary signs of clinical activity in difficult-to-treat tumour types like microsatellite stable colorectal and endometrial cancers. The drug was also well-tolerated, with a potentially best-in-class pharmacokinetic profile, according to the biotech.Sensei now expects to report additional clinical data across two dose levels from the SNS-101 dose expansion study in the first half of 2025, which will help inform the optimal dose and patient population for future Phase II testing.The company reported R&D expenses of $4.6 million in the third-quarter, and a net loss $7.3 million, which was similar to the year-ago period.Earlier this year, Kineta, which is also developing a VISTA-targeting cancer therapy, cut 64% of its staff and halted enrollment in a Phase I/II trial of KVA12123 after key investors backed out of expected funding.

Kineta Updates KVA12123 Clinical Results from Ongoing Phase 1/2 VISTA101 Study at Society for Immunotherapy of Cancer (2024)

Updated clinical data from VISTA101 presented at SITC 2024. Monotherapy arm fully enrolled and combination arm expected to be fully enrolled by year-end. Encouraging clinical responses observed in monotherapy (KVA12123 alone) and combination (KVA12123 plus Merck’s anti-PD-1 therapy, KEYTRUDA® [pembrolizumab]) cohorts. Favorable tolerability and toxicity profile in both arms, no dose limiting toxicities and a very clean safety profile observed at all dose levels in both arms of the study. SEATTLE, Nov. 08, 2024 (GLOBE NEWSWIRE) -- Kineta, Inc. (OTC Pink: KANT), a clinical-stage biotechnology company focused on the development of novel immunotherapies in oncology that address cancer immune resistance, announced today at the Society for Immunotherapy in Cancer (SITC) in Houston, TX an update on its ongoing VISTA-101 Phase 1/2 clinical trial evaluating KVA12123, an anti-VISTA monoclonal antibody, as monotherapy and in combination with Merck’s (known as MSD outside of the US and Canada) anti-PD-1 therapy, KEYTRUDA® (pembrolizumab), in patients with advanced solid tumors. KVA12123 cleared all six monotherapy dose levels and the second of four cohorts in combination with pembrolizumab. KVA12123 was well tolerated with no dose limiting toxicities (DLT) and a favorable safety profile at all dose levels in both arms of the study. The poster presentation (SITC #625): “A phase 1/2 clinical trial of antiVISTA – KVA12123 alone and in combination with pembrolizumab in patients with advanced solid tumors” was presented by Dr. Jason Henry, M.D., Sarah Cannon Research Institute at HealthONE, Denver, CO, on Friday November 8, 2024 at 9 a.m. CST. The update included the following findings (with a data cutoff date of October 18, 2024): Monotherapy Dose Escalation (3-1000 mg KVA12123 Q2W) Of the 24 patients enrolled in the six monotherapy dose cohorts, 19 patients had at least one follow-up scan and 13 of these patients experienced stable disease (iRECIST).Durable clinical outcomes have been observed in a number of monotherapy patients with one patient with non-small cell lung cancer that failed six prior lines of therapy, including checkpoint inhibitor (CPI) therapy, experiencing stable disease lasting 60 weeks.Nine of 24 monotherapy patients had prior CPI exposure. Combination Therapy Dose Escalation (30-100 mg KVA12123 Q2W, 400 mg pembrolizumab Q6W) Nine patients have been enrolled in the two combination cohorts with at least one follow-up scan: iCR and iPR responses have been observed and the combination has been well tolerated.Confirmed Partial Response in one mucoepidermoid carcinoma patient with a 54% reduction in target lesions and a confirmed complete response (CR) in non-target lesions.Stable disease in one renal cell carcinoma patient that had progressed on prior CPI therapy with a 24% reduction in target lesions. Two remaining combination cohorts are expected to be fully enrolled by year-end. Safety No DLTs observed in any patient at any dose level in either study arm.A very clean safety profile with few adverse events. “We are pleased to present our progress on the VISTA-101 clinical trial at SITC this year, with the initial clinical response data emerging from the study. We have observed promising clinical responses in this advanced cancer patient population. KVA12123 has the potential to be a new alternative for patients with hard-to-treat cancers,” said Jason Henry, M.D. “The safety profile of KVA12123 to date has been remarkable in the monotherapy as well as in combination cohorts. Initial read-outs demonstrated that KVA12123 is not only safe but exhibits potential clinical benefit for some patients as either monotherapy or combination and may offer patients a novel approach to address immunosuppression in the tumor microenvironment and better manage solid tumor cancers,” added Thierry Guillaudeux, Ph.D., Chief Scientific Officer 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. 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.
