Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Signed informed consent form and able to comply with the protocol;
• Male and female subjects ≥18 years of age;
• ECOG PS of 0 or 1, the estimated life expectancy ≥ 3 months;
• LVEF ≥ 50% as determined by echocardiography (ECHO);
• Patients must have pathologically documented advanced/unresectable or metastatic solid tumor with HER2-positive (as defined below) that is relapsed or refractory to standard therapy or for which there is no standard therapy and progressed. Patients must have a least one measurable disease lesion. Tumor specimens to identify HER2 status should be obtained within the past 6 months.
• Definition of HER2-positive
• Advanced/unresectable or metastatic breast cancer: immunohistochemistry (IHC) 3+, or IHC 2+ and in situ hybridization positive (ISH+)*;
• Advanced/unresectable or metastatic gastric or gastroesophageal junction adenocarcinoma: IHC 3+, or IHC 2+ and ISH+*;
• Other HER2-positive advanced/unresectable or metastatic solid malignant tumor: determined by IHC, ISH, Next Generation Sequencing, or other analysis techniques as appropriate;
• ISH: fluorescence in situ hybridization (FISH) or dual in situ hybridization (DISH); ISH positivity is defined as a ratio of ≥ 2.0 for the number of HER2 gene copies to the number of signals for CEP17. ISH assay is not required when IHC result is 3+. ISH assay should be performed to confirm HER2 positivity when IHC result is 2+.
• Adequate organ function confirmed at screening and within 7 days before the first treatment, as evidenced by:
• Platelet count: ≥ 100,000/mm3 ; Hemoglobin : ≥ 9 g/dL; Absolute neutrophil count (ANC): ≥ 1500/mm3 ; Serum creatinine: ≤ 1.5 × ULN (upper limit of normal), or creatinine clearance ≥ 60 mL/min (using Cockcroft Gault formula) ; Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) : ≤ 2.5 × ULN (≤ 5 × ULN if liver metastases are present); Total bilirubin : ≤ 1.5 × ULN (except for patients with Gilbert's Syndrome); Prothrombin time and activated partial thromboplastin time: ≤ 1.5 × ULN.
• Adequate washout period before the first treatment as defined by:
• Major surgery: ≥ 4 weeks. Radiation therapy: ≥ 4 weeks (≥ 2 weeks for palliative stereotactic radiation therapy without abdominal). Autologous transplantation: ≥ 3 months.
• Hormonal therapy: ≥ 2 weeks or per Investigator's discretion for breast cancer patients.
• Chemotherapy or targeted therapy (including antibody drug therapy): ≥ 3 weeks (≥ 2 weeks for 5 flourouracil-based agents, folinate agents, and/or weekly paclitaxel; ≥ 2 weeks (or 5 half-lives, whichever is shorter) for tyrosine kinase inhibitors; ≥ 4 weeks for HER2-directed biologic therapies; ≥ 6 weeks for nitrosoureas or mitomycin C). Immunotherapy: ≥ 4 weeks. Strong cytochrome P450 enzyme 3A4 (CYP3A4) inhibitor: ≥ 3 elimination half-lives . Any investigational agents or treatments: ≥ 4 weeks.
• Patients without a history of acquired immunodeficiency syndrome (AIDS)-defining opportunistic infections or with a history of AIDS-defining opportunistic infections and have not had an opportunistic infection within the past 12 months may be enrolled per the discretion of the Investigator.

You may not qualify if…

• Clinically active brain metastases, defined as untreated and symptomatic, or requiring therapy with steroids or anticonvulsants to control associated symptoms. Subjects with treated brain metastases that are no longer symptomatic and who require no treatment with steroids may be included in the study if they have recovered from the acute toxic effect of chemotherapy or radiotherapy;
• Subjects with multiple primary malignancies within 2 years, except adequately resected non-melanoma skin cancer, curatively treated in situ disease, other solid tumors curatively treated, or contralateral breast cancer);
• Cardiovascular dysfunction or clinically significant cardiac disease, including but not limited to:
• Medical history of symptomatic chronic heart failure (New York Heart Association (NYHA) classes II-IV) or serious cardiac arrhythmia requiring treatment;
• Medical history of myocardial infarction or unstable angina within 6 months of the first treatment;
• Corrected QT interval by Fridericia (QTcF) prolongation of > 450 milliseconds (ms) in males and > 470 ms in females;
• Medical history of clinically significant lung disease (e.g., interstitial pneumonia, pneumonitis, pulmonary fibrosis, and severe radiation pneumonitis), or patients who are suspected to have these diseases by imaging at screening or requirement for supplemental oxygen;
• Known hypersensitivity to either the drug substances or inactive ingredients in the drug product;
• Existing Grade ≥ 2 peripheral neuropathy;
• Unresolved toxicities from previous anticancer therapy, defined as toxicities (other than alopecia) not yet resolved to NCI CTCAE version 5.0, Grade ≤ 1 or baseline. Subjects with chronic Grade 2 toxicities may be eligible per the discretion of the Investigator;
• Cumulative anthracycline dose > 360 mg/m2 doxorubicin or equivalent;
• Uncontrolled infection requiring i.v. of antibiotics, antivirals or antifungals;
• Active infection with hepatitis C (e.g., detectable antibodies to hepatitis C virus [HCV]) or hepatitis B (e.g., hepatitis B surface antigen [HBsAg] positive) except subjects with occult or prior hepatitis B infection (defined as positive total hepatitis B core antibody and negative HBsAg) may be included if hepatitis B virus (HBV) deoxyribonucleic acid (DNA) is undetectable at the time of screening, and these subjects must be willing to undergo monthly DNA testing and appropriate antiviral therapy as indicated;
• Patients with a history or current evidence of any concomitant condition, therapy, or laboratory abnormality that, in the opinion of the Investigator, might confound the results of the trial, interfere with the patient's participation and compliance;
• Women who are lactating or pregnant, as confirmed by pregnancy test within 7 days before first treatment;
• Male and female subjects who are unwilling to use adequate contraceptive methods (e.g., concomitant use of a spermicidal agent, barrier contraceptive, or/and intrauterine contraceptive) during the study and for at least 7 months after the last dose of GQ1001.
