简要总结
Clinical Indication : HER mutated or HER2 Amplification/Overexpression in Gastric Cancer, 2nd-line Trial Type : Interventional, Open label Treatment Groups : Single arm: Pembrolizumab 200 mg every 3 weeks (Q3W), neratinib at 240 mg once daily (QD), and paclitaxel 175 mg/m2 every 3 weeks (Q3W) Number of trial participants : Approximately 68 patients will be enrolled (with 10% drop-out).
Estimated enrollment period : 24 months Estimated duration of trial : It is estimated that the trial will require approximately 30 months from the time the first patient signs the informed consent until the last patient's last visit.
- First Patient In: Mar 2021

- •total bilirubin ≤2.0 × ULN
- •creatinine ≤1.5 × ULN or creatinine clearance >60 mL/min (either measured value or estimated value using the Cockcroft-Gault equation)
- •Has failed in trastuzumab treatment for HER2-positive patients during 1st-line treatment or trastuzumab-naïve for HER2-negative patients measured by IHC or SISH/FISH.
- •Has left ventricular ejection fraction (LVEF) ≥50% measured by multiple-gated acquisition scan (MUGA) or echocardiogram (ECHO).
- •A male participant must agree to use a contraception as detailed in Appendix 3 of this protocol during the treatment period and for at least 6 months after the last dose of study treatment and refrain from donating sperm during this period.
- •A female participant is eligible to participate if she is not pregnant (see Appendix 3), not breastfeeding, and at least one of the following conditions applies:
- •Not a woman of childbearing potential (WOCBP) as defined in Appendix 3; OR
- •A WOCBP who agrees to follow the contraceptive guidance in Appendix 3 during the treatment period and for at least 6 months after the last dose of study treatment.
排除标准
- •Have received second line or more of anticancer treatment (not including adjuvant chemotherapy).
- •Have multiple cancers (with the exception of completely resected basal cell carcinoma, thyroid cancer, stage I squamous cell carcinoma, carcinoma in situ, intramucosal carcinoma, and superficial bladder cancer, and any other cancers that have not recurred for at least 5 years).

- •Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (eg., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment and is allowed.
