Description
Inclusion Criteria:
- Adults ≥ 18 years of age. Patient has TNBC; OR platinum-resistant HGSOC, primary peritoneal cancer, and/or fallopian-tube cancer; OR serous endometrial cancer, as described below.
TNBC:
- Histologically or cytologically confirmed metastatic or locally recurrent unresectable TNBC per American Society of Clinical Oncology-College of American Pathologists (ASCO-CAP) criteria.
- TNBC must have TP53 mutation/loss and be relapsed/refractory to at least 1 line of systemic chemotherapy in the metastatic setting (excluding neoadjuvant or adjuvant chemotherapies) or be intolerant of existing therapy(ies). Prior exposure to an immune checkpoint inhibitor is allowed.
- Disease must have progressed on no more than 4 prior lines of systemic therapy for locally advanced or metastatic disease (not including adjuvant or neo-adjuvant). Systemic therapy with a PARP inhibitor will be counted as 1 line of therapy.
Platinum-resistant HGSOC, primary peritoneal cancer, and/or fallopian-tube cancer:
- Histologically or cytologically confirmed diagnosis of metastatic or unresectable HGSOC, with TP53 mutation/loss, with platinum resistance defined as progression during or within 6 months of a platinum containing regimen, with no other standard treatment option available. Prior exposure to platinum-resistant recurrence therapy is allowed.
- Patients whose tumors have progressed after at least 1 line of therapy for advanced/metastatic settings.
- Systemic therapy with a PARP inhibitor will be counted as 1 line of therapy. Induction followed by maintenance will be counted as 1 line of therapy.
Serous endometrial cancer:
a. Histologically or cytologically confirmed diagnosis of metastatic or recurrent unresectable serous endometrial cancer with TP53 mutation/loss and tumor must have relapsed/be refractory to at least 1 line of systemic therapy (including immune checkpoint inhibitors) but no more than 4 lines of systemic therapy in the metastatic/recurrent setting or be intolerant of existing therapy(ies) known to provide clinical benefit for their condition.
Adequate bone marrow reserve, cardiac, liver, and renal function:
- Absolute neutrophil count (ANC) ≥ 1,500/mm3
- Platelet count ≥ 100,000/mm3
- Hemoglobin ≥ 9 g/dL
- Bilirubin ≤ 1.5 × upper limit of normal (ULN) or direct bilirubin ≤ ULN for patients with total bilirubin levels >1.5 × ULN
- Alanine aminotransferase (ALT, SGPT) and aspartate aminotransferase (AST, SGOT) ≤ 2.5 × ULN (≤ 5 × ULN if liver metastases are present)
- INR ≤ 1.5 × ULN unless patient is receiving anticoagulant therapy and PT or aPTT is within therapeutic range of intended use of anticoagulants
- Serum creatinine ≤ ULN or creatinine clearance ≥ 60 mL/min (by Cockroft Gault formula).
- Female patients of child-bearing potential must have a negative serum pregnancy test and use at least 1 form of contraception as approved by the Investigator before initiating study treatment and for 3 months after the last dose of study drug.
- Male patients must use a form of barrier contraception approved by the Investigator during the study and for 3 months after the last dose of study drug.
- Life expectancy of ≥ 3 months.
- Ability to provide written informed consent.
- An Eastern Cooperative Oncology Group (ECOG) performance status of ≤ 1.
Exclusion Criteria:
- Patients with untreated or symptomatic brain metastases and/or leptomeningeal disease (exception: treated and stable brain metastases without symptoms for ≥ 2 weeks after completion of treatment, image documentation is required, and the patient must not be taking steroids).
- Patients with a previous history of another malignancy (other than cured basal cell or squamous cell carcinoma of the skin or cured in-situ carcinoma) within 3 years of study entry.
- Patients with uncontrolled pleural effusions, pericardial effusion, or ascites that do not resolve.
- Patients with gastrointestinal tract disease causing the inability to take oral medication (e.g., swallowing difficulties, malabsorption syndromes, extensive small bowel resection [> 100cm], gastric bypass surgery).
- Pregnant or breast-feeding patients or any patient with child-bearing potential not using adequate contraception.
- Known human immunodeficiency virus, hepatitis B virus (HBV), or hepatitis C virus (HCV) infection (excluding cured HBV and/or cured HCV infection).
- Presence of any serious concomitant systemic disorders incompatible with the study in the opinion of the Investigator (e.g., uncontrolled congestive heart failure, active infection).
- Radiation therapy to > 30% of bone marrow before study entry.
- Patients who require chronic systemic steroid therapy (> 10 mg prednisone daily or equivalent) or those that are on any other form of immunosuppressive medication.
- Patients with active autoimmune disease or with a documented history of autoimmune disease.
- Patients with abnormal or clinically significant electrocardiogram (ECG) abnormality, including but not limited to a confirmed corrected QT interval using Fridericia's formula (QTcF) > 470 msec.
- Patient has received systemic anticancer therapy within 3 weeks or 5 half-lives, whichever is shorter.
- Patients must have recovered from all AEs due to previous therapies to ≤ Grade 1 or baseline.
Any of the following conditions (on-study testing is not required):
- Known HIV-infected patients unless on effective anti-retroviral therapy with an undetectable viral load within 6 months and no opportunistic infection within the past 12 months, or
- Known or suspected hepatitis B if active infection (patients with chronic hepatitis B infection must have an undetectable HBV viral load on suppressive therapy, if indicated; positive surface antibody alone is not an exclusion), or
- Known or suspected hepatitis C infection that has not been treated and cured unless currently on treatment with an undetectable viral load.
- Administration of cytochrome (CYP) 3A4 inhibitors and inducers within 14 days or 5 half-lives (whichever is shorter) prior to the administration of study drug.
