Amphista previews BRD9 degradation findings and BRAMLIE trial design at ASH

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 previews updated bexobrutideg Phase 1 CLL/SLL findings for ASH

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.

Bispecific protein drives dual receptor degradation in mouse eye-disease models

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.
