Nature Materials

In situ CAR engineering and nanoparticle-mediated TREM2 degradation for macrophage reprogramming in malignant ascites

A Nature Materials study describes mRNA-loaded LNPs that reprogram tumor-associated macrophages into Claudin18.2-targeting CAR macrophages. The lipid formulation also promotes TREM2 internalization and degradation, reshaping immune responses. The original abstract reports tumor suppression and longer survival with PD-1 blockade in mice, plus ex vivo patient-sample findings. These findings do not demonstrate clinical efficacy in treated patients.

Frontiers in Pharmacology

Review assesses the safety limits and translational gaps of MCL-1 degradation strategies

A Frontiers in Pharmacology review compares direct MCL-1 inhibition with approaches that reduce its abundance, including transcriptional interventions and targeted degradation. The original abstract highlights limited single-agent activity and cardiac safety concerns with inhibitors, while positioning degradation as an unvalidated clinical strategy. Biomarker-guided combinations and dynamic BH3 profiling are discussed; this review does not report a new clinical trial.

Evommune and Hinova / Business Wire

Evommune licenses Hinova's VAV1 molecular glue degrader outside Greater China

Evommune licensed EVO570, formerly HC118, from Hinova for development and commercialization outside Greater China. Upfront consideration totals $30 million: $20 million cash and $10 million in pre-funded warrants. Additional development, regulatory, and commercial milestones could reach approximately $1.1 billion, plus royalties. Phase 1 was expected to begin shortly; the announcement does not establish human efficacy.
