- Histological or cytological confirmation of estrogen negative and progesterone negative tumor, defined as \< 10% staining on immunohistochemistry (IHC) and human epidermal growth factor receptor type 2 (HER2)-negative, defined as HER 2 IHC 0 or 1+ or IHC 2+ with no amplification. Patients may be enrolled regardless of their PD-L1 (programmed death ligand-1) status.
- Measurable disease according to response evaluation criteria in solid tumors
- Demonstrate adequate organ function
- Female patients: All females of childbearing potential must have a negative serum β-human chorionic gonadotropin (hCG) test result at Screening and negative serum or urine pregnancy test results within 72 hours prior to day 1 of study treatment.
- Subject agrees to use contraception
- As determined by the enrolling physician, the ability of the subject to understand and comply with study procedures for the entire length of the study
- Tumor tissue: Willing to provide tumor tissue for research purposes
- Subject has a life expectancy of ≥ 12 weeks
Exclusion

- Prior therapy with the concurrent combination of gemcitabine and carboplatin in the metastatic setting
- Active, symptomatic central nervous system (CNS) metastases and/or carcinomatous meningitis or CNS metastases that are progressing on screening magnetic resonance imaging (MRI) brain.
- Prior systemic anti-cancer therapy within 3 weeks, prior stereotactic radiotherapy within 1 week, and radiation within 2 weeks of day 1 of study treatment. Participants must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis. A 1-week washout is permitted for palliative radiation to non-CNS disease.
- Major surgery, defined by the investigator's discretion, within 3 weeks of day 1 of study treatment
- Not recovered from all reversible acute toxic effects of prior therapy, including non-hematologic toxicities related to prior systemic therapy to ≤ Grade 1. Participants with less than Grade 2 neuropathy or alopecia of any grade are an exception
- Active infection requiring systemic therapy
- Pregnant or breastfeeding
- Participants previously diagnosed with an additional malignancy must be disease-free for at least five years prior to enrollment. Exceptions include basal cell or squamous cell skin cancer and in situ cervical or bladder cancer.
- Treatment with any investigational drug within 30 days or at least 5 half-lives, whichever is longer, prior to day 1 of study treatment
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, uncontrolled symptomatic congestive heart failure (Class III or IV as defined by the New York Heart Association (NYHA) functional classification system), unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations/substance abuse that would limit compliance with study requirements as determined by the investigator
- Known history of stroke or cerebrovascular event within 6 months prior to the day 1 of study treatment
- Known hypersensitivity to carboplatin or other platinum-containing compounds, gemcitabine, mannitol, or pembrolizumab
- History of non-infectious interstitial lung disease (ILD)/pneumonitis that required steroids or current ILD/ pneumonitis.
- Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e., with use of disease-modifying agents, corticosteroids, or immunosuppressive drugs) prior to day 1 of study treatment. Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment and is allowed
- Prior hematopoietic stem cell or bone marrow transplant or allogenic tissue/solid organ transplant
- Has a known history of Human Immunodeficiency Virus (HIV) or known acquired immunodeficiency syndrome (AIDS)
- Has known active hepatitis B (e.g., hepatitis B surface antigen \[HBsAg\] reactive).
- Has known active hepatitis C (e.g., hepatitis C virus (HCV) ribonucleic acid (RNA) \[qualitative\] is detected).
- Receipt of a live, attenuated vaccine within 30 days prior to day 1 of study treatment or anticipation that such a live, attenuated vaccine will be required during the study treatment period. Administration of killed vaccines is allowed. Exception: Monkeypox vaccine may be given if there are at least 3 days between the vaccine and initiation of study treatment.
