Summary
This is a 2-part trial: a Phase 1, open-label, dose-escalation study in participants with metastatic or locally advanced solid tumors, with a consecutive Phase 2 expansion to evaluate efficacy in participants with recurrent, unresectable, or metastatic (advanced) cervical cancer that has progressed after a platinum-based treatment regimen.
Eligibility Criteria
Inclusion Criteria
- Voluntarily agree to participate by giving written informed consent. Participation in pharmacogenomics testing is optional.
- Be ≥18 years of age.
- Diagnosis and prior systemic treatment:
- Phase 1: Have a histologically or cytologically confirmed diagnosis of a metastatic or locally advanced solid tumor for which no standard therapy is available or standard therapy has failed.
- Phase 2: I. Have (1) a histologically or cytologically confirmed diagnosis of squamous-cell carcinoma, adenosquamous carcinoma, or adenocarcinoma of the cervix, and (2) metastatic, locally advanced, and/or unresectable disease at the time of enrollment. Histologic confirmation of the original primary tumor is required via pathology report. Note: The following cervical tumors are not eligible: minimal deviation/adenoma malignum, gastric type adenocarcinoma, clear cell carcinoma, and mesonephric carcinoma. II. Has cervical cancer and has relapsed after a platinum-based treatment (first line) regimen for advanced (recurrent, unresectable, or metastatic) disease; Note: Participants who have received >1 prior systemic treatment regimen for their advanced or metastatic disease will be eligible in the following cases: Participant receiving chemotherapy concurrently with primary radiation (for example, weekly cisplatin) or participant receiving adjuvant chemotherapy following completion of radiation therapy (for example, paclitaxel and carboplatin for ≤4 cycles) and progressed within 6 months after treatment completion.
- Measurable disease - based on investigator assessment
- Phase 1: Have objective evidence of disease; the presence of measurable disease is not required.
- Phase 2: Have measurable disease on imaging based on Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1). Note: Participants must have at least one "target lesion" to be used to assess response, as defined by RECIST 1.1. Tumors within a previously irradiated field will be designated as "non-target" lesions unless progression is documented or a biopsy is obtained to confirm persistence at least 90 days following completion of radiation therapy. Note: Measurable disease by RECIST 1.1 must be confirmed by independent central radiologic review prior to first dose. Participants without centrally confirmed measurable disease at baseline will not be eligible for this trial.
- Have a life expectancy of at least 3 months and an Eastern Cooperative Oncology Group performance status of 0 or 1.
- Have adequate organ function as indicated by the following laboratory values:
- Adequate hematological function defined by absolute neutrophil count ≥1.5 x 10^9/liter (L), platelet count ≥100 x 10^9/L, and stable hemoglobin ≥8 grams/deciliter (without transfusions within 1 week before first dose).
- Adequate hepatic function based by a total bilirubin level ≤ the institutional upper limit of normal (IULN), aspartate aminotransferase level ≤2.5 x IULN, alanine aminotransferase level ≤2.5 x IULN, and alkaline phosphatase ≤2.5 x IULN.
- Adequate renal function defined as creatinine ≤1.5 x IULN or calculated creatinine clearance ≥50 milliliters/minute for participants with creatinine levels >1.5 x IULN (if no local guideline is available, creatinine clearance should be calculated using the Cockcroft-Gault Method).
- Adequate coagulation defined by international normalized ratio or prothrombin time ≤1.5 x IULN (unless the participant is receiving anticoagulant therapy); and activated partial thromboplastin time ≤1.5 x IULN (unless the participant is receiving anticoagulant therapy)
- Other than the cancer for which the participant is enrolled, have no history of prior malignancy, with the exception of basal cell carcinoma of the skin, superficial bladder cancer, squamous-cell carcinoma of the skin, or has undergone potentially curative therapy with no evidence of that disease recurrence for 5 years since initiation of that therapy.
- In Phase 2, particip
