12. Female subjects must meet the following conditions: infertility or fertility and use high-efficiency contraceptive measures during the study and for 6 months following the last dose of the study drug infusion.

Exclusion Criteria

1. Have active brain parenchymal metastasis. Patients with clinically stable brain parenchymal metastases can be included, including asymptomatic brain metastases that have not received local treatment; or patients who have previously received central nervous system metastasis therapy (radiotherapy or surgery), if imaging confirms that stability has been maintained for at least 4 weeks, and have stopped symptomatic treatment (including hormones and mannitol, etc.) for more than 4 weeks CNS (central nervous system) metastasis with clinical symptoms;

2. Have previously been treated with: another antibody-drug conjugate (ADC) consisting of DM1 or its derivative; previously received capecitabine (end of adjuvant therapy>1 year and not receive capecitabine after relapse were allowed); previously received pyrotinib (end of (neo)adjuvant therapy>6 months and no pyrotinib treatment after relapsed were allowed; received pyrotinib in metastatic settings and stopped for reasons other than disease progression and had disease progression after 6 months were allowed.

3. Have other malignant tumors within 5 years before signing the informed consent form ( except for cured skin basal cell carcinoma and cervical carcinoma in situ).;

4. The toxicity of previous anti-cancer therapy has not recovered to ≤1 as specified in CTCAE v5.0 (except for hair loss); chronic grade 2 toxicity might be determined per the investigator's judgment.

5. History of allergic reaction to any component of GQ1001.

6. Have a medical history of myocardial infarction, symptomatic congestive heart failure (CHF) (NYHA classes II-IV), unstable angina or serious cardiac arrhythmia within 6 months.

7. Have a corrected QT interval (QTc) prolongation to > 450 milliseconds (ms) in males and > 470 ms in females.

8. Have a history of (noninfectious) interstitial lung disease (ILD)/pneumonitis requiring steroids, current ILD/pneumonitis, or suspected ILD/pneumonitis that cannot be ruled out by imaging at screening.
