Intervention/exposure
Study type
Interventional
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.

Outcomes
Primary outcome [1] 323602 0
Dose Limiting Toxicities (DLTs). Adverse events will be assessed using NCI CTCAE version 5.0 and will be evaluated by the investigator and the sponsor for the eligibility of DLT.
Timepoint [1] 323602 0
End of Cycle 1 (21-day cycle)
Secondary outcome [1] 382332 0
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.

AEs will be graded according to the Common Toxicity Criteria for Adverse Events (CTCAE) version 5.0. Known/possible AEs and assessments include:
- 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
- increased AST/ALT assessed by blood biochemistry assessment
Timepoint [1] 382332 0
Safety lab and AE assessment will be conducted weekly in the first cycle and at least every 3 weeks or more often in the following cycles.
