CatégorieGPRC5D × Entraîneur bispécifique de cellules T CD3 (IgG4) humanisé
MécanismeHumanized IgG4 bispecific antibody binding GPRC5D (G-protein- coupled receptor family C group 5 member D, highly expressed on malignant plasma cells with restricted normal-tissue expression to keratinized epithelia + hair follicles + tongue) on one arm and CD3 on T-cells. Redirects T-cell cytotoxicity to GPRC5D+ myeloma. First-in-class non-BCMA bispecific — orthogonal target for patients progressing on BCMA-directed therapy. On-target off-tumor toxicity profile reflects normal GPRC5D expression (taste/skin/nail toxicities).
Dose typiqueTwo approved schedules: weekly 0.4 mg/kg SC (step-up: 0.01 → 0.06 → 0.4 mg/kg SC q3-4d) or biweekly 0.8 mg/kg SC (step-up: 0.01 → 0.06 → 0.3 → 0.8 mg/kg SC). Hospitalization required for step-up doses. Maintenance until progression. Biweekly schedule preferred for prolonged therapy (improved tolerability; reduced infection surveillance burden).

Notes

MonumenTAL-1 (Chari 2022, NEJM): triple-class refractory MM after ≥4 prior lines — ORR ~73% (weekly cohort), ~74% (biweekly cohort), mDOR ~9-13 mo. FDA accelerated approval Aug 2023; EMA Aug 2023. Distinctive toxicity profile: taste/oral/nail/skin AEs reflect GPRC5D expression in keratinized tissues — manageable but quality- of-life-impacting; nutrition + dental support critical. Lower infection burden vs BCMA bispecifics (different antigen niche; intact humoral immunity). Useful for sequencing post-BCMA failure (orthogonal target). Bibliographic record SRC-MONUMENTAL-1-CHARI-2022 is available; clinical claim linkage requires dual clinical sign-off.
