Advanced Solid Tumors

Brief summary

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 The study includes JS019 monotherapy dose escalation, dose expansion stages to investigate the safety, tolerability, pharmacokinetics and preliminary anti-tumor efficacy of JS019 as monotherapy.

Detailed description

Monotherapy Dose Escalation Stage: In this stage, the safety and tolerability, PK characteristics, immunogenicity and pharmacodynamics characteristics of JS019 are investigated. Four dosage groups are preset: 0.3 mg/kg, 1 mg/kg, 3 mg/kg and 10 mg/kg. The drug is administered intravenously every 3 weeks (Q3W). A treatment cycle is 21 days, with a DLT observation period of 21 days after the initial administration. The incremental dose and dosing interval may be adjusted as necessary during the study based on safety, PK, and other results obtained Monotherapy Dose Expansion Stage: According to RP2D of JS019 single drug dose, 3-5 specific tumor types are selected for indication expansion, and about 8-12 patients are enrolled for each indication. Tumor types and additional cases could be selected according to the specific situation in the trial process. It is planned to expand the cohort of lung cancer, pancreatic cancer, sarcoma, hepatocellular carcinoma, cholangiocarcinoma and other solid tumors to explore the efficacy and safety of JS019 single drug. The specific cohort will be adjusted according to the results of previous studies.

Interventions

BIOLOGICALJS019

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.

Primary

MeasureTime frameDescription
Safety Incidence of DLT severity of adverse events (AEs) and serious adverse events (SAEs)and tolerability2 yearsIncidence of DLT, incidence and severity of adverse events (AE) and severe adverse events (SAE), clinically significant abnormal laboratory changes and other tests
Maximum Tolerated Dose (MTD) or Optimal Biological Effect Dose (OBD) and Phase II study recommended dose (RP2D)2 yearsThe safety, pharmacokinetic and preliminary efficacy data of the comprehensive dose escalation were determined. When MTD/OBD is determined, MTD/OBD is usually used as RP2D.

Secondary

Pharmacodynamics (PD)2 yearsCD39 receptor occupancy in peripheral blood.
Objective response rate (ORR)2 yearsThe percentage of cases with remission (PR + CR) after treatment was assessable
Duration of response (DOR)2 yearsThe time from the first assessment of CR or PR to the first assessment of PD or death due to any cause.
Pharmacokinetics (PK)2 yearsDrug concentrations in individual subjects at different time points after administration
Time to response (TTR)2 yearstime from the start of treatment to progression of diease.
Progression-free survival (PFS)2 yearsPFS is defined as time from the start of treatment to progression of disease or death.
Overall survival (OS)2 yearsOverall survival is defined as time from the start of treatment until death due to any reason.
Disease control rate (DCR)2 yearsThe percentage of cases with remission (PR + CR) and stable lesions (SD) after treatment was assessable.
Immunogenicity2 yearsIncidence of anti-drug antibodies (ADA), titer of ADA-positive samples.
