BioAtla to Host Virtual R&D Day to Review BA3071 CAB-CTLA-4 Phase 1 Data in Multiple Solid Tumor Types on Wednesday, December 13, 2023

SAN DIEGO, Dec. 06, 2023 (GLOBE NEWSWIRE) -- BioAtla, Inc. (Nasdaq: BCAB), a global clinical-stage biotechnology company focused on the development of Conditionally Active Biologic (CAB) antibody therapeutics for the treatment of solid tumors, today announced it will host a virtual R&D Day on Wednesday, December 13, 2023 at 10:00 AM ET. To register, click here.

The event will feature Omid Hamid, MD (Cedars Sinai: The Angeles Clinic and Research Institute), who will review Phase 1 dose escalation trial results for BA3071, a novel conditionally and reversibly active antibody targeting CTLA-4. BA3071 is in Phase 2 development as a potential therapeutic for multiple solid tumor indications known to be responsive to CTLA-4 treatment in combination with a PD-1 blocking agent.

A live question and answer session will follow the formal presentation.

About Omid Hamid, MD

Omid Hamid, MD, is Chief, Translational Research and Immunotherapy, and Director, Melanoma Therapeutics at The Angeles Clinic and Research Institute. As the Director of the Melanoma Center and Phase I Immuno-Oncology Program, Dr. Omid Hamid works to ensure that patients receive access to the most up-to-date therapeutics. Most recently, in his role with the Phase 1 Developmental Therapeutics Program, Dr. Hamid has been instrumental in bringing new therapies from the investigational lab to the clinic for patient benefit. These therapies involve Immuno-Oncologic therapies such as PD-1 inhibitors (Keytruda, Nivolumab, Atezolizumab) and other checkpoint inhibitors, therapies against tumor angiogenesis, and targeted agents that block internal processes in tumor cell’s function (BRAF/MEK). Dr. Hamid’s research focus involves manipulation of a patient’s immune system to attack cancer cells and maintain continuously elevated levels of immunity and discovery of novel therapies. His research began in melanoma and has now extended into paradigm shifting trials for all cancers. Dr. Hamid is recognized nationally and internationally as a key opinion leader in Immuno-Oncologic Drug Development and Melanoma Therapeutics. Through his role as the Chief of Immunotherapy and Translational Research, patients at The Angeles Clinic have benefited from first-in-class, paradigm shifting drugs. Dr. Hamid was an investigator in the initial trials with Ipilimumab, Pembrolizumab, Nivolumab, Atezolizumab and Vemurafenib, agents that led to significant survival benefits in the lives of patients. Through his leadership, the next phase of agents have become available to patients. He has been a key investigator on combinations of BRAF/MEK inhibitors and novel immune therapy with PD-1 antibodies, and continues to be at the forefront of drug development. His current work focuses on Next-Generation Checkpoint Inhibitors, including antiOX40, 41BB, and GITR antibodies, with a focus on bringing T-cell adoptive therapies and bispecific antibodies. Dr. Hamid has presented research done at The Angeles Clinic at major national and international meetings, including the American Society of Clinical Oncology (ASCO), Society for Melanoma Research, and many other key national and international meetings. He has published manuscripts, abstracts, and reviews on immunotherapy, targeted therapy, and melanoma care in prestigious journals, such as the Journal of Clinical Oncology (JCO), New England Journal of Medicine (NEJM), and Clinical Cancer Research.

About BA3071

BA3071 is a CAB anti-CTLA-4 antibody that is being developed as an immuno-oncology agent with the goal of delivering efficacy at least comparable to the approved anti-CTLA-4 antibodies, but with lower toxicities due to the CAB's tumor microenvironment-restricted activity. This is expected to enable safer anti-CTLA-4 antibody combination therapies, such as with anti-PD-1 antibody checkpoint inhibitors, and potentially broaden the patient population tolerant to combination therapy and deliver greater efficacy. Like our other CAB candidates, this Phase 2 clinical asset is designed to be conditionally and reversibly active in the tumor microenvironment. BA3071 is being developed as a potential therapeutic for multiple solid tumor indications that are known to be responsive to CTLA-4 treatment in combination with a PD-1 blocking agent.

About BioAtla^®, Inc.

BioAtla is a global clinical-stage biotechnology company with operations in San Diego, California, and in Beijing, China through our contractual relationship with BioDuro-Sundia, a provider of preclinical development services. Utilizing its proprietary Conditionally Active Biologics (CAB) technology, BioAtla develops novel, reversibly active monoclonal and bispecific antibodies and other protein therapeutic product candidates. CAB product candidates are designed to have more selective targeting, greater efficacy with lower toxicity, and more cost-efficient and predictable manufacturing than traditional antibodies. BioAtla has extensive and worldwide patent coverage for its CAB technology and products with greater than 700 patents filed, more than 400 of which have been issued. Broad patent coverage in all major markets include methods of making, screening and manufacturing CAB product candidates in a wide range of formats and composition of matter coverage for specific products. BioAtla has two first-in-class CAB programs currently in Phase 2 clinical testing, mecbotamab vedotin, BA3011, a novel conditionally active AXL-targeted antibody-drug conjugate (CAB-AXL-ADC), and ozuriftamab vedotin, BA3021, a novel conditionally active ROR2-targeted antibody-drug conjugate (CAB-ROR2-ADC). The Phase 2 stage CAB-CTLA-4 antibody, BA3071, is a novel CTLA-4 inhibitor designed to reduce systemic toxicity and potentially enable safer combination therapies with checkpoint inhibitors such as anti-PD-1 antibody. The company’s first bispecific T-cell engager antibody, BA3182, is currently in Phase 1 development. BA3182 targets EpCAM, which is highly and frequently expressed on many adenocarcinomas while engaging human CD3 expressing T-cells. To learn more about BioAtla, Inc. visit www.bioatla.com.
