• 1 other identifier: BL-M08D1-205
• Study Type: interventional
• Target: 30
• Locations: 1 country
• Sites: 2

Brief Summary

This Phase Ib/II study is a clinical trial to evaluate the efficacy and safety of BL-M08D1 for Injection in patients with recurrent or metastatic nasopharyngeal carcinoma and other solid tumors.

Conditions

Nasopharyngeal Carcinoma (NPC); Solid Tumors

Outcome Measures

Primary Outcomes (2)

• Recommended Phase II Dose (RP2D)

  The RP2D is defined as the dose level chosen by the sponsor (in consultation with the investigators) for phase II study, based on safety, tolerability, efficacy, PK, and PD data collected during the dose escalation study of BL-M08D1.

  Up to approximately 24 months

• Objective Response Rate (ORR)

  ORR is defined as the percentage of participants, who has a CR (disappearance of all target lesions) or PR (at least a 30% decrease in the sum of diameters of target lesions). The percentage of participants who experiences a confirmed CR or PR is according to RECIST 1.1.

  Up to approximately 24 months

Secondary Outcomes (11)

• Progression-free Survival (PFS)

  Up to approximately 24 months

• Disease Control Rate (DCR)

  Up to approximately 24 months

• Duration of Response (DOR)

  Up to approximately 24 months

• Treatment-Emergent Adverse Event (TEAE)

  Up to approximately 24 months

• Cmax

  Up to approximately 24 months

Study Arms (1)

EXPERIMENTAL

Participants receive BL-M08D1 for the first cycle (3 weeks). Participants with clinical benefit could receive additional treatment for more cycles. The administration will be terminated because of disease progression or intolerable toxicity occurring or other reasons.

Drug: BL-M08D1

Interventions

BL-M08D1 DRUG

Administration by intravenous infusion for a cycle of 3 weeks.

BL-M08D1
