A Study of DM002 in Patients With Advanced Solid Tumors

Exclusion Criteria

• •1. Subjects have another active invasive malignancy within 5 years, with the following exceptions and notes:
• •1. History of noninvasive malignancy, such as cervical cancer in situ, in situ melanoma, or ductal carcinoma in situ of the breast that is in complete remission 5 years after treatment with curative intent is allowed.
• •2. Malignancies with a negligible risk of metastasis or death (such as adequately treated basal or squamous cell skin cancer and localized prostate cancer).
• •2. Current or history of a hematologic malignancy.
• •3. Anticancer therapy (chemotherapy, immunotherapy, hormonal therapy, targeted therapy, biologic therapy, or other anti-cancer therapies, except for hormones for hypothyroidism or estrogen replacement therapy, anti-estrogen analogs, agonists required to suppress serum testosterone levels) within 28 days or 5 half-lives, whichever is shorter, prior to the first study dose. Radiotherapy with a wide field of radiation within 28 days, or radiotherapy with a limited field of radiation for palliation within 14 days of the first study dose. Major surgery, other than diagnostic surgery, within 4 weeks of the first study dose.
• •4. Primary central nervous system (CNS) malignancies or CNS metastases. Individuals with brain metastases can be enrolled only if treated, nonprogressive brain metastases and off high-dose steroids (\>20 mg prednisone or equivalent) for at least 4 weeks.
• •5. History of known allergies to ADC, or prior discontinuation of an ADC due to treatment-related toxicities. Has received prior treatment with ADCs that include topoisomerase I (Topo I) payload, and treatment history with any investigational drug within 4 weeks before enrolment in the study.
• •6. Has an uncontrolled infection requiring IV injection of antibiotics, antivirals, or antifungals.
• •7. Has a pre-existing clinically significant lung diseases (e.g., interstitial pneumonia, pneumonitis, pulmonary fibrosis, and severe radiation pneumonitis) or pre-existing ocular disorders.
• •8. Clinically uncontrolled intercurrent illness, including but not limited to an ongoing active infection, active coagulopathy, uncontrolled cardiovascular disease, uncontrolled immune disease, uncontrolled diabetes, uncontrolled pleural and peritoneal effusion, psychiatric illness that would limit compliance with the study requirements and other serious medical illnesses requiring systemic therapies.
• •9. Mean resting corrected QT interval corrected by Fridericia's formula (QTcF) \>470 msec obtained from triplicate 12-lead ECGs at baseline; using concomitant medications that would prolong the QT interval.
• •10. Left ventricular ejection fraction \<50% by either an echocardiogram (ECHO) or a multi-gated acquisition scan within 28 days before first dose of the study drug.
• •11. Known active hepatitis B (HBV) or hepatitis C (HCV) infection. Chronic carriers of HBV infection (HBsAg-positive, undetectable HBV DNA or HBV DNA ≤2500 copies/ml or 500 IU/ml) receive prophylactic treatment during the study can be enrolled. Participants with a history of HCV infection have completed curative antiviral treatment and HCV viral load below the limit of quantification and HCV antibody positive but HCV ribonucleic acid (RNA) negative due to prior treatment or natural resolution should be eligible.
• •12. Known human immunodeficiency virus (HIV) infection which is not well controlled. Participants should be tested for HIV prior to enrollment if required by local regulations or institutional review board (IRB)/ethics committee. All the following criteria are required to define an HIV infection (positive HIV1/2 antibodies test) that is well controlled: HIV viral load \<400 copies/mL, CD4+ T- cell counts ≥350 cells/μL, no history of acquired immunodeficiency syndrome-defining opportunistic infection within the past 12 months, and stable viral load for at least 4 weeks on same anti-HIV retroviral medications.
• •17. Participants who are of reproductive potential refuse to use effective methods of birth control during participation of the study and within 7 months for female (and 4 months for male) after the last dose administration.
• •18. Participants who took drugs or food which can strongly inhibit or induce the cytochrome P450 (CYP) isoenzyme, CYP3A4/5 within 2 weeks prior to the first dose of DM002 or within 5 half-lives, whichever is longer.
