Who can join

Age: 18 and older. Sex: female. Healthy volunteers: not accepted.

You may qualify if…

• 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, participants must provide a sufficient and adequate formalin-fixed paraffin-embedded tumor tissue sample preferably from the most recent biopsy of a tumor lesion, collected either at the time of or after the diagnosis of advanced or metastatic disease has been made and from a site not previously irradiated. If no tumor tissue is available, a fresh biopsy will be required.
• Note: Tissue from needle or excisional biopsy or from resection is required.
• Female participants must have a negative serum pregnancy test at screening (within 72 hours before first dose of study drug) if of childbearing potential or be of non-childbearing potential. Non-childbearing potential is defined as (by other than medical reasons):
• ≥45 years of age and has not menstruated for greater than 1 year,
• Amenorrheic for <2 years without a hysterectomy and oophorectomy and a follicle-stimulating hormone value in the postmenopausal range upon pretrial (screening) evaluation,
• Whose status is post hysterectomy, oophorectomy or tubal ligation.
• If of childbearing potential, female participants must be willing to use 2 highly effective methods (defined in the informed consent form [ICF]) throughout the study, starting with the screening visit through 120 days after the last dose of study treatment.
• Note: Abstinence is acceptable if this is the established and preferred contraception for the participant.
• Male participants with a female partner(s) of childbearing potential must agree to use 2 highly effective methods (defined in the ICF) throughout the trial starting with the screening visit through 120 days after the last dose of study treatment is received. Males with pregnant partners must agree to use a condom; no additional method of contraception is required for the pregnant partner.
• Note: Abstinence is acceptable if this is the established and preferred contraception for the participant.

You may not qualify if…

• Is currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapy or used an investigation device within 4 weeks before the first dose of treatment.
• Has an inadequate washout period prior to first dose of study drug defined as:
• Received systemic cytotoxic chemotherapy or biological therapy within 3 weeks before first dose,
• Received radiation therapy within 3 weeks before first dose, or
• Had major surgery within 4 weeks before first dose.
• Has received prior therapy with:
• Any antibody/drug targeting T-cell co-regulatory proteins (immune checkpoints) such as anti-PD-1, anti-programmed cell death ligand 1, or anti-cytotoxic T-lymphocyte antigen 4 (CTLA-4) antibodies
• For Phase 2: >1 systemic treatment regimen for the advanced (recurrent, unresectable, or metastatic) cervical cancer for which the participant is considered for the study Note: In Phase 1, prior treatment with a CTLA-4 antibody is permissible for participants with metastatic melanoma.
• Has persisting toxicity related to prior therapy of National Cancer Institute Common Terminology Criteria for Adverse Events version 4.03 (NCI CTCAE) Grade >1 severity.
• Note: Sensory neuropathy or alopecia of Grade ≤2 is acceptable.

• Has known severe hypersensitivity reactions to fully human monoclonal antibodies (NCI CTCAE Grade ≥3), any history of anaphylaxis, or uncontrolled asthma.
• Is receiving systemic corticosteroid ≤7 days prior to the first dose of trial treatment or receiving any other form of systemic immunosuppressive medication (corticosteroid use on study for management of immune-related adverse events, and/or a premedication for IV contrast allergies/reactions is allowed). Participants who are receiving daily corticosteroid replacement therapy are an exception to this rule. Examples of permitted therapy are daily prednisone at doses of 5 to 7.5 mg or equivalent hydrocortisone dose, and steroid therapy administered by topical, intraocular, intranasal, and/or inhalation routes.
• Has a central nervous system tumor, metastasis(es), and/or carcinomatous meningitis identified either on the baseline brain imaging obtained during the screening period or identified prior to consent. Note: Participants with history of brain metastases that have been treated may participate provided they show evidence of stable supra-tentorial lesions at screening (based on 2 sets of brain images, performed ≥4 weeks apart, and obtained after the brain metastases treatment). In addition, any neurologic symptoms that developed either as a result of the brain metastases or their treatment must have resolved or be minimal and be expected as sequelae from treated lesions. For individuals who received steroids as part of brain metastases treatment, steroids must be discontinued ≥7 days prior to first dose of study drug.
• Has active or history of autoimmune disease that has required systemic treatment within 2 years of the start of trial treatment (that is, with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (that is, thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment. Note: Participants with type 1 diabetes, vitiligo, psoriasis, hypo-, or hyperthyroid disease not requiring immunosuppressive treatment are eligible.
