Amphista announced an ASH oral presentation on AMX-883-mediated BRD9 degradation, describing disruption of hematopoietic transcriptional programs, myeloid differentiation, and reduced leukemic stem-cell frequency in experimental work. A separate abstract outlines the ongoing Phase 1 BRAMLIE study in AML and high-risk myelodysplastic syndrome. The announcement does not establish clinical efficacy for AMX-883.
Nurix announced updated Phase 1a/1b findings for its oral BTK degrader bexobrutideg (NX-5948) in relapsed or refractory CLL/SLL. The ASH presentation will include patients previously exposed to covalent BTK inhibitors and data at the recommended Phase 2 dose of 600 mg once daily. The release describes durable activity without providing numerical response rates.

A PNAS study reports RHV, a tetravalent bispecific protein designed to internalize and lysosomally degrade VCAM-1 and VEGFR on pathological vessels. The original abstract describes activity in mouse choroidal neovascularization models, including efficacy comparable to aflibercept at one-quarter of the molar dose. This is preclinical extracellular receptor degradation, distinct from an intracellular small-molecule PROTAC.

This is the same asset as Photys's, not another independent drug. Website projections for KRAS, EGFR, and DAC clinical entry are not actual dosing evidence. HPB-092 is an inhibitor and is excluded from the degradation pipeline.
