A single arm, open-label Phase II clinical study.The subjects were patients with lung, gastric and colorectal cancers.

Detailed Description

Object: 1.The main purpose: T To observe and evaluate the efficacy of pyrotinib in patients with HER2-mutated/amplified metastatic solid tumors after failure of standard therapy; 2. Secondary objectives: To observe and evaluate the safety of pyrotinib in patients in HER2 mutated or amplified metastatic solid tumors after failure of standard treatment.

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

A single arm, open-label Phase II clinical study.

All subjects enrolled will receive the following treatment：Pyrotinib±standard treatment.

Pyrotinib 400 mg/ D (once a day, at the same time each day) until the progression of disease; Chemotherapy regimens follow the programme cycle recommended by the guidelines or as determined by the investigator.

The dosage can be adjusted according to the protocol according to the adverse reactions of subjects. Subjects will continue to take medication until completion of the prescribed course of treatment, disease progression, toxicity intolerance, withdrawal of Informed Consent Form, or termination in the investigator's judgment.
