Immunome, Inc. (Nasdaq: IMNM), a biotechnology company focused on the development of first-in-class and best-in-class targeted oncology therapies, today announced financial results for the second quarter ended June 30, 2024, and provided a business update.

“Immunome is focused on establishing and developing a broad pipeline of differentiated oncology therapies. We continue to advance work required to prepare AL102 for regulatory submissions, and we are moving towards submitting INDs for IM-1021 and IM-3050,” said Clay B. Siegall, Ph.D., President and Chief Executive Officer. “These programs are supported by an expanding team of drug developers, including leaders who previously contributed to the successful development and commercialization of ADCs and small molecules.”

Dr. Siegall continued, “In addition to our clinical pipeline, we have identified multiple promising ADC targets, all of which offer first-in-class potential. We believe that cost-effective business development efforts combined with focused research can accelerate the expansion of our pipeline and that rigorous science provides the foundation for transformative cancer therapies.”

Pipeline Highlights

Full enrollment for the Phase 3 RINGSIDE Part B study of AL102 for the treatment of desmoid tumors was completed in February 2024, and Immunome continues to expect to report topline data for RINGSIDE Part B in the second half of 2025. In parallel, Immunome is performing additional manufacturing and pharmacology work required to support a new drug application filing for AL102.

Immunome also anticipates submitting INDs for IM-1021 and IM-3050 in the first quarter of 2025, as previously disclosed.

These programs are complemented by robust discovery efforts centered on next-generation ADCs and active business development activity, including recent transactions with Atreca, Nectin Therapeutics, Bluefin Biomedicine, and OncoResponse intended to expand Immunome’s ADC toolbox.
