Study 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/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.

Read the detailed description

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.

Exclusion criteria

Exclusion Criteria:

  1. Patients with known hypersensitivity to the components of JS019;
  2. Patients who have received the treatment with anti-CD39 antibodies or inhibitors;
  3. Patients who participated in other clinical studies within 4 weeks prior to the first administration of JS019, except patients are in the follow-up period of observational (non-interventional) clinical study or interventional study;
  4. Patients who have received major surgery within 4 weeks before the first dose or expected to undergo major surgery during the study (as judged by the investigator) or are in the recovery period from surgery;
  5. Patients who have received anti-tumor therapy, such as chemotherapy, radiotherapy, targeted therapy, immunotherapy, or biological therapy, within 4 weeks or 5 half-lives of the therapy (whichever is shorter) prior to the first dose of JS019. Patients who have received traditional Chinese medicine or Chinese patent medicine preparations with anti-tumor indications within 2 weeks before the first dose of JS019. Can accept hormone therapy for non-tumor-related diseases (such as insulin therapy for diabetes and hormone replacement therapy, etc.);
  6. Patients who have discontinued immunotherapy due to immune-related AEs.
  7. Patients who have used immunosuppressive drugs within 4 weeks prior to the first dose of JS019, with the exception of intranasal and inhaled corticosteroids or systemic corticosteroids ≤10 mg/day prednisone or equivalent.

What researchers measure

Primary outcomes

  1. Safety and tolerability

    Incidence of DLT, incidence and severity of adverse events (AEs) and serious adverse events (SAEs), clinically significant abnormal changes in laboratory tests and other tests

    Time frame: 2 years

  2. Maximum tolerated dose (MTD, if possible) and the recommended phase 2 dose (RP2D)

    Maximum tolerated dose (MTD) : The highest dose at which \<1/3 patients experience DLT events. Phase II recommended dose: safety, pharmacokinetics, and preliminary efficacy data of dose escalation will be integrated. When the Maximum tolerated dose(MTD) is determined, the Maximum tolerated dose(MTD) is usually used as the Phase II recommended dose(RP2D), or the dose lower than the Maximum tolerated dose(MTD) is selected as the Phase II recommended dose(RP2D) based on the comprehensive data.

    Time frame: 2 years

Secondary outcomes

  1. Pharmacokinetics (PK)

    Drug concentrations in individual subjects at different time points after administration

    Time frame: 2 years

  2. Immunogenicity

    Incidence of anti-drug antibodies (ADA), titer of ADA-positive samples.

    Time frame: 2 years

  3. Pharmacodynamics (PD)

    CD39 receptor occupancy in peripheral blood.

    Time frame: 2 years

  4. Objective response rate (ORR)

    The percentage of cases with remission (PR + CR) after treatment was assessable

    Time frame: 2 years

  5. Duration of response (DOR)

    The time from the first assessment of CR or PR to the first assessment of PD or death due to any cause.

    Time frame: 2 years

  6. Disease control rate (DCR)

    The percentage of cases with remission (PR + CR) and stable lesions (SD) after treatment was assessable.

    Time frame: 2 years

  7. Time to response (TTR)

    time from the start of treatment to progression of diease.

    Time frame: 2 years

  8. Progression-free survival (PFS)

    PFS is defined as time from the start of treatment to progression of disease or death.

    Time frame: 2 years

  9. Overall survival (OS)

    Overall survival is defined as time from the start of treatment until death due to any reason.

    Time frame: 2 years
