Advanced Solid Tumors or Lymphomas Clinical Trial
Official title:
A Phase 1 Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Preliminary Efficacy of Recombinant Fully Human Anti-CD39 Monoclonal Antibody JS019 in Patients With Advanced Solid Tumors or Lymphomas
This is a phase 1 clinical study to evaluate the safety, tolerability, pharmacokinetics and preliminary efficacy of JS019 as monotherapy in patients with advanced malignant solid tumors/lymphomas. The study includes JS019 monotherapy dose escalation, dose expansion and indication expansion stages to investigate the safety, tolerability, pharmacokinetics and preliminary anti-tumor efficacy of JS019 as monotherapy.
Monotherapy Dose Escalation Stage: In this stage, the safety and tolerability, PK characteristics, immunogenicity and PD of JS019 are investigated. Four dose levels are preset: 0.3 mg/kg, 1 mg/kg, 3 mg/kg, and 10 mg/kg. The subjects are treated with JS019 by intravenous infusion, once every 3 weeks (Q3W). A treatment cycle is 21 days, and the DLT observation period is 21 days after the first administration. During the study, necessary adjustments may be made to the escalating dose and dosing interval based on the safety, PK and other results obtained. Monotherapy Dose Expansion Stage: SMC will select 1~2 dose levels (dose levels in the monotherapy dose escalation stage or intermediate dose levels) of JS019 as monotherapy. Each dose level includes 6~9 subjects with advanced malignancies to further evaluate the safety, pharmacokinetics, immunogenicity, pharmacodynamics and efficacy of JS019 as monotherapy, and determine the RP2D of JS019 as monotherapy. Monotherapy Indication Expansion Stage Based on the determined RP2D of JS019 as monotherapy, 2-4 specific malignancies are selected for indication expansion; about 20-30 patients are included for each indication. It is planned to include expansion cohorts to explore the efficacy and safety of JS019 as monotherapy. The actual cohorts included may be adjusted based on the results of the previous studies. ;
