About ISB 2001

ISB 2001 is a first-in-class trispecific T-cell engager that targets BCMA and CD38 on myeloma cells and CD3 on T cells currently in Phase 1 for relapsed/refractory multiple myeloma. Developed using IGI's proprietary BEAT® protein platform, ISB 2001 was engineered with two distinct binders against myeloma-associated antigens to enhance avidity, even at low target expression levels, while aiming to improve safety over first-generation bispecific antibodies.  Recently presented at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting as a Rapid Oral Presentation (Abstract #7514), data from 35 patients demonstrated a sustained overall response rate (ORR) of 79% and a high complete/stringent complete response (CR/sCR) rate of 30% at active doses ≥ 50 µg/kg in a heavily pretreated population of relapsed/refractory myeloma patients, with a favorable safety profile.

U.S. Food & Drug Administration granted ISB 2001 Orphan Drug Designation in July 2023 and Fast Track Designation for the treatment of relapsed/refractory myeloma patients in May 2025. 

About the BEAT® Multispecific™ Platform

IGI's proprietary BEAT® platform goes beyond traditional bispecific antibody approaches, addressing key engineering bottlenecks that have historically limited large-scale bispecific production. By leveraging a proprietary common light chain library and TCR interface-based heavy chain pairing, BEAT® enables the development of next-generation immune cell engagers with strong therapeutic potential in oncology. Unlike many engineered formats, BEAT® mirrors the architecture of natural antibodies utilizing both light and heavy chains to enhance stability and function. Key attributes of the BEAT® platform include its multispecific versatility, enabling the design of antibodies that engage diverse immune cell types such as T cells, myeloid cells, and NK cells against multiple antigens. The platform also features optimized engineering through high-fidelity heavy chain pairing with a common light chain, allowing for precise Fc modulation and access to a broad structural design space. Additionally, BEAT® supports robust manufacturability, producing correctly assembled multispecific antibodies with favorable stability, extended half-lives, low immunogenicity and high titer yields through standardized process development and manufacturing operations.

About IGI 

IGI is a global, fully integrated clinical-stage biotechnology company focused on developing innovative biologics in oncology. Headquartered in New York, NY, IGI is advancing a robust pipeline of novel, first-in-class multispecifics^TM aimed at addressing complex diseases and treating patients holistically.
