$40M Series A. First patient dosed in Phase 1 for RLS-1496 — first GPX4 modulator targeting pathological senescent cells via ferroptosis. Novel senolytic mechanism.
Rubedo Life Sciences is a senolytic drug company that has advanced RLS-1496 into Phase 1 clinical trials — the first GPX4 (glutathione peroxidase 4) modulator designed to selectively eliminate pathological senescent cells through ferroptosis, a form of programmed cell death. The company has raised $40 million in Series A financing and dosed its first patient in June 2025, with a systemic formulation entering Phase 1 planned for 2026 that would dramatically broaden its clinical scope.
Received up to $40.7M ARPA-H award (Oct 2025). Polymeric nanoparticle platform to reprogram immune cells in vivo without viral vectors. Non-viral delivery for CAR-T-like therapies.
ImmunoVec is developing a non-viral polymeric nanoparticle delivery platform for in vivo immune cell engineering — programming a patient's immune cells directly inside their body without the expensive ex vivo manufacturing process that makes CAR-T therapies cost $500,000-$1,000,000 per treatment. The company received a selective ARPA-H (Advanced Research Projects Agency for Health) award of up to $40.7 million in October 2025 for development of its platform.
