Eligibility Criteria
Inclusion Criteria
- •Metastatic or locally advanced solid tumor malignancies (breast cancer, urothelial cancer, ovarian cancer, melanoma, NSCLC, renal cell carcinoma, squamous cell cancer of the head and neck, colorectal cancer, and hepatocellular carcinoma) that has progressed on, is refractory to, intolerant to, or for which there is no curative standard of care therapy.
- •Measurable disease with at least 1 lesion amenable to response assessment per RECIST 1.
- •Demonstrate adequate organ function. All screening laboratories should be performed within 14 days of treatment initiation.
- •Has a performance status of 0-2 on the ECOG Performance Scale.
- •Life expectancy \>12 weeks at baseline.
- •Women of childbearing potential must have negative serum or urine pregnancy test within 72 hours prior to receiving the first study drug administration. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
- •Women of childbearing potential must be willing to use an adequate method of contraception from 30 days prior to the first study drug administration and 120 days following last day study drug administration.
- •Male patients of childbearing potential must be surgically sterile, or must agree to use adequate method of contraception during the study and at least 120 days following the last day of study drug administration.
- •Age ≥18 years at screening.
- •Able and willing to provide written informed consent and to follow study instructions.
Exclusion Criteria
- •Patient has disease that is suitable for therapy administered with curative intent.
- •Untreated or uncontrolled central nervous system (CNS) involvement.
- •Any concurrent or recent use (within 28 days or 5 half-lives, whichever is longer) of chemotherapy, immunotherapy, or biologic or hormonal therapy for cancer treatment.
- •Unresolved toxicities from prior therapy, defined as having not resolved to NCI CTCAE v5.0 Grade 0 or 1, with exception of alopecia and vitiligo.
- •Systemic corticosteroids at doses exceeding 10 mg/day prednisone or equivalent.
- •Patient has an active infection requiring systemic therapy.
- •Patients who have known active HIV, Hepatitis or active COVID-19 infection. (Patients who have been vaccinated against Hepatitis B and who are positive only for the Hepatitis B surface antibody are permitted to participate in the study). Patients who are positive for hepatitis B or C virus must be tested for and have an undetectable viral load.
- •Patients with unstable/inadequate cardiac function:
