ImmunoPrecise Antibodies, ImmunoPrecise Antibodies Ltd., an AI-driven biotherapeutic research and technology company, proudly announces the clinical progress achieved with rabbit monoclonal antibodies designed and developed using IPA’s proprietary B Cell Select® platform for the clinical-stage company, OncoResponse Inc. This achievement underscores IPA’s leadership as a Contract Research Organization creating high-quality therapeutic antibodies, while pioneering work in the field of rabbit monoclonal antibody development. These antibodies are rapidly gaining recognition as a unique tool in therapies due to their distinctive properties, advancing into clinical trials aimed at improving patient outcomes.
OncoResponse’s Breakthrough in Cancer Treatment
In a live presentation at the recent PEGS 2024 conference, OncoResponse shared exciting updates on two novel antibodies, OR502 and OR641, both of which were discovered and refined using IPA’s innovative B Cell Select® platform:
- OR502, a novel, humanized anti-leukocyte immunoglobulin like receptor B2 (LILRB2) antibody, has successfully entered Phase I/II clinical trials, showing excellent safety profile, and is being evaluated for efficacy in treating advanced solid tumors. Preclinical models have demonstrated that OR502 is a best-in-class anti-LILRB2 antibody that reverses immunosuppression caused by myeloid cells in the TME.
- OR641, a novel, humanized dual antagonist antibody targeting both LILRB1 and LILRB2, has completed Cell Line Development and is undergoing IND-enabling studies. Preclinical models have demonstrated its superior ability to reverse immunosuppression caused by myeloid and lymphoid cells compared to other anti-LILRB1/2 antibodies.
Driving Antibody Discovery and Design for Clinical Success
IPA’s proprietary B Cell Select® platform has been instrumental in the rapid design and discovery of antibodies that have advanced to clinical stages for numerous clients. By preserving the natural structure of antibodies, IPA’s technology supports optimal functioning of the therapies in a clinical setting. Through comprehensive testing and validation, the process ensures that these antibodies maintain their efficacy and reliability from the lab to the clinic.

Harnessing Rabbit B Cell Technology for Breakthrough Antibody Discovery
The Rabbit B Cell platform, a rapidly advancing technology in therapeutic antibody development, played a pivotal role in the discovery process. This platform excels at generating high-affinity and highly specific rabbit monoclonal antibodies, a demand met with very limited providers in the market.
IPA has successfully utilized their B Cell Select platform in over 200 antibody programs, achieving remarkable success against a variety of targets, including small molecules, peptides, and proteins. The distinctive properties of rabbit antibodies, combined with IPA’s expertise, have consistently led to the development of promising therapeutic candidates. Building on this success, IPA is now offering more complex therapeutic rabbit antibody campaigns as a partnering model, providing companies with greater flexibility in structuring their more complicated programs.
Outlook
The field of rabbit monoclonal antibody (mAb) therapeutics is advancing rapidly, driven by innovations in antibody engineering and humanization techniques. These advancements are making rabbit mAbs increasingly popular for human therapeutic use. The unique properties of rabbit antibodies, combined with IPA’s full-service technologies, such as in silico humanization, indicate a strong potential for more rabbit-derived mAbs to enter clinical trials and achieve approval in the coming years. The distinctive advantages of rabbit antibodies make them a promising foundation for future therapeutic development. As this technology progresses, IPA remains at the forefront, harnessing these innovations to bring new, effective treatments to the clinic, reinforcing our growing leadership in the industry.
Dr. Kamal D. Puri, Chief Scientific Officer of OncoResponse, recognized IPA’s pivotal role in their success, praising the quality and reliability of IPA’s antibody discovery services. “We are thrilled to have worked with IPA to discover our lead therapeutic antibodies. The IPA team’s deep experience and know-how with a battery of customized, high-throughput discovery strategies has played a critical role in the successful discovery of our molecules with unsurpassed speed and efficiency,” said Kamal D. Puri, Chief Scientific Officer of OncoResponse.
