PHASE 1 STUDY OF SL0349, A BISPECIFIC NANOBODY BASED BCMA/GPRC5D CAR-T, IN RELAPSED OR REFRACTORY MULTIPLE MYELOMA (EHA 2026) - P1 | "The SL0349 CAR transgene concentrations (mean maximum concentration [C max ]=535071 copies/µg DNA) showed maximum peripheral expansion at a median of 13.5 (range: 10-21) days. Summary/Conclusion This analysis of the phase 1 study establishes a positive risk–benefit profile for a single low-dose infusion of SL0349, yielding early, deep responses in heavily pretreated RRMM patients, particularly for patients with high-risk cytogenetic features and/or EMD lesions."
