Open to people ages 18 years and up
Part 2 Only
- Has a histologically confirmed advanced or metastatic non-small cell lung cancer (NSCLC), non-microsatellite instability-high colorectal neoplasms (non-MSI-H CRC) or pancreatic adenocarcinoma, and centrally confirmed Human Leukocyte Antigen (HLA) HLA-A1101 and/or HLA-C0802 allele expression by HLA typing
- Has a histologically confirmed advanced or metastatic KRAS 4MUT+ (G12D, G12V, G13D or G12C) (4 prevalent KRAS mutant antigens in solid tumors) solid tumor identified by central laboratory testing, and who have received, or been intolerant to, or ineligible for all treatment known to confer clinical benefit.
- A male participant must agree to use study-approved contraception during the treatment period and for at least 120 days after the last dose of study intervention and refrain from donating sperm during this period.
- A female participant was not be pregnant, not breastfeeding, and at not be a woman of childbearing potential (WOCBP) OR if a WOCBP, agrees to follow study-approved contraceptive guidance during treatment period and for at least 120 days after the last dose of study intervention.
- Have measurable disease per RECIST 1.1 as assessed by the local site investigator/radiology. Lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions.
- For Part 1 only: Cutaneous lesions can be considered in addition to imaging, but measurable disease should be defined by radiologic assessment.
- Have an evaluable archival tumor sample to submit for analysis. Formalin-fixed, paraffin embedded (FFPE) tissue blocks are preferred to slides.
- Have adequate organ function
- Have a performance status of 0 or 1 on the Eastern Cooperative Oncology Group (ECOG) Performance Scale.
You CAN'T join if...
- A WOCBP who has a positive urine pregnancy test within 72 hours prior to randomization or treatment allocation
- Has an active infection requiring therapy.
- Has a history of interstitial lung disease.
- Has an active autoimmune disease that has required systemic treatment in the past 2 years (ie, with use of disease modifying agents, corticosteroids, or immunosuppressive drugs) except vitiligo or resolved childhood asthma/atopy.
- Has not fully recovered from any effects of major surgery or has evidence of detectable infection. Surgeries that required general anesthesia must be completed at least 2 weeks before first study treatment administration. Surgery requiring regional/epidural anesthesia must be completed at least 72 hours before first study treatment administration and participants should be recovered.
- Has had chemotherapy, definitive radiation, or biological cancer therapy within 4 weeks (2 weeks for palliative radiation) prior to the first dose of study therapy, non-cytotoxic small molecule therapeutics within 5 half-lives (or 2 weeks, whichever is longer) prior to the first dose of study treatment, or has not recovered to Common Toxicity Criteria for Adverse Events (CTCAE) Grade 1 or better from any adverse events that were due to cancer therapeutics administered more than 4 weeks earlier (this includes participants with previous immunomodulatory therapy with residual immune-related adverse events).
- Has received a live-virus vaccine within 30 days of planned treatment start. Seasonal flu vaccines that do not contain live virus are permitted.
- Has received hematopoietic colony-stimulating growth factors (eg, granulocyte-colony stimulating factor, granulocyte-macrophage-colony stimulating factor, macrophage colony stimulating factor) within 2 weeks prior to the first dose of study intervention.
- Discontinued from therapy with an anti-programmed cell death protein 1 (anti-PD-1), anti-PD-L1, or anti-PD-L2 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (TCR; eg, cytotoxic T lymphocyte-associated antigen 4 (CTLA-4), CD137 (4‐1BB, Tumor necrosis factor‐receptor superfamily 9 [TNFSF9]), and OX 40 (TNFRSF4), due to a Grade 3 or higher immune-related adverse event (irAE).
- Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 28 days prior to the first dose of study intervention.
- Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior the first dose of study drug.
- Has a known additional malignancy that is progressing or has required active treatment within the past 2 years.
- Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis.
- Has severe hypersensitivity (≥Grade 3) to pembrolizumab and/or any of its excipients.
- Has a history of (non-infectious) pneumonitis that required steroids or has current pneumonitis.
- Has a known history of Hepatitis B (defined as Hepatitis B surface antigen [HBsAg] reactive) or known active Hepatitis C virus (defined as HCV ribonucleic acid (RNA) [qualitative] is detected) infection.
- Has a known history of HIV.
- Has a known psychiatric or substance abuse disorder that would interfere with cooperating with the requirements of the study.
- Is pregnant or breastfeeding or expecting to conceive or father children within the projected duration of the study, starting with the screening visit through 120 days after the last dose of study intervention.
- Has had an allogenic tissue/solid organ transplant.
