Eligibility Criteria

Inclusion Criteria:

Written informed consent provided prior to any screening procedures.
Male or female patients, ≥18 years of age at the time of obtaining informed consent.
Patients with histologically or cytologically confirmed advanced solid tumors previously treated with standard of care systemic therapy, or for whom no standard therapy is available.

Willingness to provide archival tumor tissue collected within the previous 2 years, when available. If no archival tissue is available that was collected within a 2 year timeframe, willingness to undergo a pretreatment biopsy if medically feasible and safe.

For patients on Phase 1b dose expansion, willingness to undergo pre- and on-treatment biopsies if medically feasible and safe.
Measurable disease per RECIST 1.1.
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 and life expectancy of ≥12 weeks.

Adequate organ function as defined by:

Absolute neutrophil count (ANC) ≥1.5 x 109/L (1500/µL), without colony-stimulating factor support for the past 14 days.
Platelets ≥100.0 x 109/L (100 000/µL).
Hemoglobin ≥9.0 g/dL (without blood transfusion in 2-week period prior to screening laboratory tests).
Creatinine clearance (CrCl) ≥45 mL/min as calculated by the Cockcroft-Gault method.
Serum total bilirubin ≤ 1.5 x the upper limit of normal (ULN).
Aspartate aminotransferase (AST) ≤2.5 x ULN; alanine aminotransferase (ALT) ≤ 2.5 x ULN.
International normalized ratio (INR) ≤ 1.5; activated partial thromboplastin time (aPTT) ≤ 1.5 x ULN.
Left ventricular ejection fraction (LVEF) ≥50% as per echocardiography (ECHO) or multi-gated acquisition scan (MUGA).
Q wave to T wave (QT) interval corrected for heart rate (QTc) ≤480 ms (Fridericia's formula).

Women of child-bearing potential (WCBP), defined as a sexually mature woman who has not undergone surgical sterilization or who has not been naturally postmenopausal for at least 12 consecutive months (i.e., who has had menses any time in the preceding 12 consecutive months) must agree to use 2 effective contraceptive methods; examples include oral, parenteral, or implantable hormonal contraceptive, intra-uterine device, barrier contraceptive with spermicide, partner's latex (or polyisoprene, if latex allergy) condom or vasectomy while on study treatment and for at least 12 weeks after the last dose of the study drug.

WCBP must have a negative serum pregnancy test within 72 hours prior to first dose of the study drug.
Male patients must agree to use a latex (or polyisoprene, if latex allergy) condom, even if they had a successful vasectomy, while on study treatment and for at least 12 weeks after the last dose of the study drug.
Patients must be willing and able to sign the informed consent form, and to adhere to the study visit schedule and other protocol requirements.

Exclusion Criteria:

Prior treatment an ADC with a topoisomerase I (TOP1) payload.
Active or progressing brain metastases or evidence of leptomeningeal disease. Stable/treated brain metastases are permitted (defined as history of brain metastases previously treated with surgical resection or stereotactic radiosurgery, stable on baseline screening study MRI brain for at least 2 months (compared to comparator MRI brain) and asymptomatic without requirement for steroids or antiseizure medications.
Persistent toxicities from previous systemic antineoplastic treatments of Grade >1, excluding alopecia and vitiligo.
Systemic antineoplastic therapy within 5 half-lives or 4 weeks, whichever is shorter, prior to first dose of the study drug, including investigational agents.
Wide-field radiotherapy (e.g., >30% of marrow-bearing bones) within 4 weeks, or focal radiation with palliative intent outside the field of measurable disease within 2 weeks prior to first dose of the study drug.
Major surgery (not including placement of vascular access device or tumor biopsies) within 4 weeks prior to first dose of study drug, or no recovery from side effects of such intervention.
Has had clinically significant lung disease requiring systemic corticosteroid treatment within the last 6 months of randomization/registration (e.g., interstitial pneumonia, pneumonitis, pulmonary fibrosis, and severe radiation pneumonitis) or who are suspected to have such diseases by imaging at screening period.
Patients with acute or chronic pancreatitis and/or any cirrhosis except cirrhosis diagnosed as Child-Pugh class A.
Hepatic insufficiency manifesting as clinical jaundice, hepatic encephalopathy, and/or variceal bleed within 60 days prior to study entry.
History of liver transplant.
Prior allogeneic bone marrow transplantation.
Significant cardiac disease, such as recent (within 6 months prior to first dose of the study drug) myocardial infarction or acute coronary syndromes (including unstable angina pectoris), congestive heart failure (New York Heart Association class III or IV), uncontrolled hypertension, uncontrolled cardiac arrhythmias, severe aortic stenosis.
History of thromboembolic or cerebrovascular events, including transient ischemic attacks, cerebrovascular accidents, deep vein thrombosis, or pulmonary emboli within 3 months prior to first dose of the study drug.

Acute and/or clinically significant bacterial, fungal, or viral infection including hepatitis B (HBV), hepatitis C (HCV), known human immunodeficiency virus (HIV).

Note: patients with chronic HBV, HCV or HIV infection will be eligible if they are considered upon a mutual agreement of the Investigator and the Medical Monitor as safe for enrollment and meet one of the following additional conditions:
Patients with HIV infection are on an established antiretroviral therapy for at least 4 weeks, and have CD4+ T-cell counts ≥350 cells/µL and HIV viral load <400 copies/mL,
Patients with serologic evidence of chronic HBV infection receive concurrent anti-HBV therapy and have HBV viral load below the limit of quantification,
Patients with a history of HCV infection must have completed curative anti-HCV therapy and have HCV viral load below the limit of quantification,
Patients on concurrent anti-HCV therapy have HCV viral load below the limit of quantification.
Known or suspected allergy to the study drug or any component of the study drug.
Concurrent participation in another investigational clinical trial.
Pregnant or breast-feeding females.

Prior history of malignancy other than inclusion diagnosis within 3 years prior to first dose of the study drug.

Note: patients with adequately treated basal cell or squamous cell skin cancer, non-invasive superficial bladder cancer, in situ cervical cancer, in situ breast cancer, in situ prostate cancer may be eligible if have shown no evidence of active disease for 2 years prior to first dose of drug.
Any other severe acute or chronic medical or psychiatric conditions or laboratory abnormality that may increase the risk associated with the study participation or the study drug administration or may interfere with the interpretation of study results and, in the judgment of the Investigator, would make the patient inappropriate for enrollment in this study.
