Interventions

NameTypeDescription
HMPL-A251DRUGSix dose cohorts are planned for the Dose Escalation phase; at least three participants with solid tumors will be enrolled in each dose cohort. Bayesian optimal interval design with backfill (BF-BOIN, Zhao, 2023) will be used to guide dose escalation and determine the MTD and/or RDE of HMPL-A251. All study participants will receive HMPL-A251 as IV infusion until PD, intolerable toxicity, or other protocol-specified criteria for ending study treatment, whichever occurs first.
