简要总结
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.
详细描述
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.

- •Live vaccines within 28 days prior to the first dose of study and during trial treatment.
- •Patient has an active autoimmune disease or a documented history of autoimmune disease (but not limited In terstitial lung Disease, uveitis, SLE, etal). Patients with vitiligo or resolved childhood asthma/atopy would be exception to this rule. Patients that require inhaled steroids or local steroid injections would not be excluded from the study. Patients with vitiligo or psoriasis that is stable on hormone replacement will not be excluded from the study.
- •Active and clinically significant bacterial, fungal or viral infection including hepatitis B (HBV), hepatitis C (HCV), known human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS)-related illness.
- •Patients have uncontrollable systemic disease which including diabetes, hypertendion, pulmonary fibrosis, etal.
- •The toxicity of previous anti-cancer therapy has not returned to 0 or 1 level as specified in CTCAE v4.0 (except for hair loss);
- •Patient has a history of allogeneic HSCT or organ transplation before study entry;
- •Patients with hypersensitivity or delayed hypersensitivity reactions to certain components of RC48-ADC or similar drugs;
- •Patients with symptomatic include but not limited ascites or pleural effusion and mental disease.
