Brief Summary:
This is a non-randomized, open-label, single-arm, multicenter Phase I clinical trial which will evaluate the Safety, Efficacy, Tolerability and Pharmacokinetics of RC48-ADC in combinaton with Anti-PD1 Monoclonal Antibody in Treatment of HER2-Positive Advanced Malignant Solid Tumors.

Condition or disease Intervention/treatment Phase
HER2-Positive Solid Tumors Biological: RC48-ADC in combinaton with JS001 Phase 1

Detailed Description:

The study has 2 parts which include dose escalation phase and dose extension phase.

Dose escalation will use a 3+3 design and will enroll cohorts of 3-6 patients with HER2-Positive Advanced Malignant Solid Tumors sequentially at escalating doses of 2.0mg/kg and 2.5mg/kg to RC48-ADC and JS001 is fixed dose of 3.0mg/mg . Escalation will continue until identification of a MTD.

Dose of phase II and extenstion stage which based-results of escalation phase will be recommend.

Primary Outcome Measures :
  1. DLT(dose-limiting toxicity) [ Time Frame: 28 days ]
    Side effects of drug or treatment that are serious enough to prevent an increase in dose or level of that treatment.

  2. ORR [ Time Frame: From date of first dose until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 24 months ]
    Percentage of patients who achieve partial response (PR) or complete response (CR) based on Response Evaluation Criteria In Solid Tumors (RECIST v1.1).

  3. DOR [ Time Frame: From date of first dose until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 24 months ]
    The percentage of patients who achieve complete remission(CR) or partial remission (PR) or stable disease(SD) determined by the RECIST v1.1 criteria.


Secondary Outcome Measures :
  1. PFSR of 6-month and 1-year [ Time Frame: 6 months and 12 months ]
    progression free survival rate

  2. CBR(clinical benefit rate) [ Time Frame: up to 2 years ]
    The percentage of patients who have achieved complete response, partial response and stable disease to the therapeutic intervention.

  3. adverse events [ Time Frame: 1 year ]
    Safety of participants followed for the duration of hospital stay, an expected average of 1 week

  4. ADA [ Time Frame: up to 2 years ]
    anti-drug antibody which can result in treatment failure by blocking the pharmacological function of the drug.

  5. NADA [ Time Frame: up to 2 years ]
    neutralizing anti-drug antibody which can result in treatment failure by blocking the pharmacological function of the drug.

  6. Cmax [ Time Frame: up to 3 cycles(each cycle is 14 days) ]
    Peak plasma concentration

  7. AUC [ Time Frame: up to 3 cycles(each cycle is 14 days) ]
    area under the plasma concentration versus time curve

  8. Tmax [ Time Frame: up to 3 cycles(each cycle is 14 days) ]
    Time for peak concentration
