Inclusion criteria
Key Inclusion Criteria: * Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 or 1. * Histologically or cytologically-documented, incurable locally advanced or metastatic solid tumor of one of the following types: * Cohort A: oesophageal squamous-cell carcinoma that was refractory or intolerant to fluoropyrimidine-based, platinum-based, and taxane-based chemotherapy. * Cohort B: gastric adenocarcinoma that was refractory or intolerant to fluoropyrimidine-based, platinum-based, and taxane-based chemotherapy. * Cohort C: cervical cancer that was refractory or intolerant to platinum-based and taxane-based chemotherapy. * Cohort D: biliary tract cancer, including intrahepatic cholangiocarcinoma (IHCC), extrahepatic cholangiocarcinoma (EHCC), and gallbladder cancer (GBC), with exception of ampullary carcinoma, progressed during or after first line platinum-based or fluoropyrimidine-based chemotherapy. * Cohort E: lung adenocarcinoma with activating genomic alterations (EGFR/ ALK/ ROS1/ BRAF/ MET/ RET) that was refractory or intolerant to targeted tyrosine kinase inhibitors (TKIs) and had not received platinum-based chemotherapy for unresectable local advanced or metastatic disease, and no suitable or willing to receive platinum-based chemotherapy. * Measurable disease by computed tomography (CT) or magnetic resonance imaging (MRI) in accordance with RECIST v 1.1, bone-only disease is not measurable and is not permitted. * Availability of archival tumor tissue or newly acquired biopsy (unstaining tumor slides, recommended from metastasis sites). * Adequate bone marrow, hepatic and renal function. * Recovered from all prior treatment-related toxicities to Grade 1 or less by NCI-CTCAE v 5.0 (except alopecia or peripheral neuropathy that may be Grade 2 or less). * Individuals must have completed all prior cancer treatments at least 2 weeks prior to the first dose including chemotherapy , radiotherapy and major surgery. Prior antibody treatment for cancer must have been completed at least 3 weeks prior to the first dose. * Individuals must have at least a 3-month life expectancy. Key
Exclusion criteria
* Previous treatment with topoisomerase I inhibitors as a free form or as other formulations. * Previous treatment with Trop-2 targeted therapy. * Individuals with a history of or current central nervous system (CNS) metastases. * Known additional malignancy within 3 years prior to enrollment with the exception of curatively treated basal cell carcinoma of the skin, squamous cell carcinoma of the skin and/or curatively resected in situ cancers. * Individuals known to be human immunodeficiency virus positive. * Individuals with active hepatitis B virus (HBV), or hepatitis C virus (HCV) infection. Hepatitis B core antibody (HBcAb) testing is required and if positive, then HBV DNA testing will be performed and if positive the individual will be excluded. * Known history of unstable angina, myocardial infarction (MI), or chronic heart failure present within 6 months of first dose or clinically significant cardiac arrhythmia (other than stable atrial fibrillation) requiring anti-arrhythmia therapy or left ventricular ejection fraction \< 50%. * Known history of clinically significant active chronic obstructive pulmonary disease, or other moderate-to-severe chronic respiratory illness present within 6 months of the first dose. * Infection requiring systematic antibiotic use within 1 week of the first dose. * Individuals with active chronic inflammatory bowel disease (ulcerative colitis, Crohn disease) and individuals with a history of bowel obstruction or gastrointestinal (GI) perforation. * High dose systemic corticosteroids within 2 weeks prior to the first dose (however, low dose corticosteroids ≤ 10 mg prednisone or equivalent daily are permitted provided the dose is stable for 4 weeks). * Individuals who have received a live vaccine within 30 days of first dose.
