A Study to Assess the Safety and Efficacy of LB1410 in Participants With Advanced Solid Tumor or Lymphoma（Keyplus-001）
Study Details
Study Description
Brief Summary
This is a Phase I study designed to evaluate if experimental anti-PD-1 and anti-TIM-3 bispecific antibody, LB1410, is safe, tolerable and efficacious in participants with advanced solid tumors or lymphoma.
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|
| Phase 1 |
Detailed Description
This first time in patients, open-label, multi-centre study will have LB1410 administered intravenously (IV) to participants with advanced solid tumors or lymphoma. This study will have 2 parts: Part A which will have dose escalation cohorts and Part B which will have the dose expansion cohorts.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Dose Escalation Up to 9 dose cohorts will be sequentially enrolled in the dose escalation part using an accelerated titration combined with the standard 3+3 dose escalation algorithm approach. |
Drug: LB1410
anti-PD-1 and anti-TIM-3 bispecific antibody
|
| Experimental: Safety Expansion 2-3 doses were initially selected for safety expansion, with patients with advanced solid tumors as the main research population. Each dose cohort is expected to enroll 9-12 patients. |
Drug: LB1410
anti-PD-1 and anti-TIM-3 bispecific antibody
|
| Experimental: Exploratory Expansion The Cohort Exploratory Expansion will enroll subjects by cohort at the RP2D dose, and a total of 4 cohorts (cohorts A, B, C, D) are expected. |
Drug: LB1410
anti-PD-1 and anti-TIM-3 bispecific antibody
