Description of intervention(s) / exposure
The name of the drug being administered is GQ1001. GQ1001 is an Antibody-Drug Conjugate used to treat patients with HER2-positive advanced solid tumors. GQ1001 will be administered by the licensed medical staff at the clinical site as a single intravenous dose on Day 1 of a 21-day treatment cycle. Patient medical records, routine safety lab tests and other necessary medical monitoring will be conducted by the investigators and site medical staff during the study.
Eligible patients will be enrolled into one specific dose cohort following the study progress. Intra-patient dose escalation will not be allowed. Dose cohorts planned for the dose escalation are 1.2 mg/kg, 2.4 mg/kg, 3.6 mg/kg, 4.8 mg/kg, and 6.0 mg/kg. Eight cycles treatment was planned for each enrolled patient. The safety review by the Safety Review Committee (SRC) will occur on a continual basis through the duration of the study. The SCR will monitor the safety and provide decisions as to dose escalations and exploring intermediate or higher doses. Patients may stay on the study treatment longer, until disease progression occurs, unacceptable toxicity occurs, or voluntarily withdraw the consent.

Safety and tolerability. Safety and tolerability will be assessed by incidence and severity of adverse events (AEs) and/or by abnormal laboratory values, vital signs, ECGs, or ECOG performance status.

- neutropenia assessed by lab hematology assessment
- anemia assessed by lab hematology assessment
- thrombocytopenia assessed by lab hematology assessment
- heart failure assessed by ECG or Echocardiography
- left ventricular ejection fraction assessed by Echocardiography
- electrolyte abnormality assessed by blood biochemistry assessment
- increased bilirubin assessed by blood biochemistry assessment

Summary
Brief summary
This purpose of this study is to determine a safe dose for GQ1001 in patients with HER-2 Positive Advanced Solid Tumors
Who is it for?
You may be eligible to join this study if you are aged 18 years and older, and have pathologically documented solid tumor with HER2 expression
Study details
All participants in this study will receive the study drug (called GQ1001). There will be 5 groups of patients who each receive a different dose. The drug will be given once intravenously (through the vein) on Day 1 of a 21-day cycle. Participants will be monitored for reactions and treatment effectiveness, and provide blood and urine for analysis.
It is hoped that this research will improve the health outcomes of patients with HER2-positive advanced solid tumors.
