You may be eligible if
Capable of giving signed, written informed consent.
Male or female, age 18 to 93 years (at the time consent is obtained).
Histological or cytological documentation of an invasive malignancy that was diagnosed as locally advanced/metastatic or relapsed/refractory and is of one of the following tumor types: bladder/urothelial cancer of the upper and lower urinary tract; cervical; colorectal (includes appendix); esophagus, squamous cell; head and neck carcinoma; melanoma; malignant pleural mesothelioma (MPM); non-small-cell lung cancer (NSCLC), prostate; Microsatellite Instability-High/deficient mismatch repair (MSI-H/dMMR) tumor (Part 1B and Part 2B) and Human Papilloma Virus (HPV)-positive or Epstein-Barr (EBV)-positive tumor (Part 1B and Part 2B).
Disease that has progressed after standard therapy for the specific tumor type, or for which standard therapy has proven to be ineffective, intolerable, or is considered inappropriate, or if no further standard therapy exists; exceptions are in these tumor types in which pembrolizumab single agent may be a standard: NSCLC, head and neck squamous cell cancer (HNSCC), bladder/urothelial cancer, MSI-H/dMMR cancers and melanoma and cervical cancer. In Part 2B pembrolizumab combination expansion cohorts, prior treatment with anti-Programmed cell death protein 1(PD-1)/ Ligand-1 (L1) may not be required. 1) Participants must not have received more than 5 prior lines of therapy for advanced disease including both standards of care and investigational therapies. 2) Participants who received prior PD-1/L1 therapy must fulfill the following requirements (Part 1B \[except PK/PD cohort\]/ Part 2B):a) Have achieved a CR, PR or SD and subsequently had disease progression while still on PD-1/L1 therapy; b) Have received at least 2 doses of an approved PD-1/L1 inhibitor (by any regulatory authority), c) Have demonstrated disease progression as defined by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 within 18 weeks from the last dose of the PD-1/L1 inhibitor. The initial evidence of disease progression is to be confirmed by a second assessment no less than four weeks from the date of the first documented Progressive Disease (PD) (the confirmatory scan could be the Baseline eligibility scan for this study). 3) In Part 2A 5-fluorouracil (FU)/platinum combination with GSK3359609 and pembrolizumab cohort, participants must not have received prior systemic therapy administered in the recurrent or metastatic setting (with the exception of systemic therapy given as part of multimodal treatment for locally advanced disease).
Archival tumor tissue obtained at any time from the initial diagnosis to study entry; a fresh tumor biopsy using a procedure that is safe for the participant on a lesion not previously irradiated unless lesion progressed will be required if archival tissue is unavailable.
Agree to undergo a pre-treatment and on treatment biopsy and have disease amenable to biopsy required in pharmacokinetic (PK) / pharmacodynamics (PD), dose randomized HNSCC, Melanoma dose expansion and Biomarker cohorts..
Measurable disease per RECIST version 1.1. Palpable lesions that are not measurable by radiographic or photographic evaluations may not be utilized as the only measurable lesion. Any measurable lesion biopsied at Screening cannot be followed as a target/index lesion unless agreed upon by GlaxoSmithKline (GSK).
Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0-1.
Life expectancy of at least 12 weeks.
Adequate organ function.
QT interval corrected for heart rate according to Fridericia's formula (QTcF) \<450 milliseconds (msec) or QTcF \<480 msec for participants with bundle branch block.
A female participant is eligible to participate if she is not pregnant (as confirmed by a negative serum beta-human chorionic gonadotrophin \[beta-hCG\] test in females of reproductive potential), and not lactating or reproductive potential agrees to follow one of the options listed in protocol from 30 days prior to the first dose of study medication and until 120 days after the last dose of study treatment.
Male participants with female partners of child bearing potential must agree to use one of the methods of contraception specified in protocol from time of first dose of study treatment until 120 days after the last dose of study treatment.
Documented HPV/ EBV-positive tumor as determined by a local laboratory for Part 1B and Part 2B pembrolizumab combination viral-positive expansion cohorts only.
Documented MSI-H or dMMR-positive tumor as determined by local laboratory for Part 1B and Part 2B pembrolizumab combination MSI-H/dMMR expansion cohorts only.
ICOS expression result using an analytically validated immunohistochemistry (IHC) assay by central laboratory for Part 1B biomarker cohort only.
Gene expression (GEX) result using an analytically validated method by central laboratory (Part 1B Biomarker Cohort only).
PD-L1 combined positive score (CPS) \<1 using the Food and Drug Administration (FDA) approved PD-L1 IHC 22C3 pharmdx assay by central laboratory testing for Part 2B HNSCC PD-L1 CPS \<1 Cohort. Documented test result from FDA approved PD-L1 IHC 22C3 pharmDx assay in local laboratory, if available, may be accepted in lieu of the central laboratory test result.
You may not be if
Prior treatment with the following therapies:
• Anticancer therapy within 30 days or 5 half-lives of the drug, whichever is shorter. At least 14 days must have elapsed between the last dose of prior anticancer agent and the first dose of study drug is administered.
• Part 2B (GSK3359609/pembrolizumab combination): prior pembrolizumab washout is not required.
• Prior radiation therapy: permissible if at least one non-irradiated measurable lesion is available for assessment according to RECIST version 1.1 or if a solitary measurable lesion was irradiated, objective progression is documented. A wash out of at least two weeks before start of study drug for radiation of any intended use to the extremities for bone metastases and 4 weeks for radiation to the chest, brain, or visceral organs is required. • Investigational therapy within 30 days or 5 half-lives of the investigational product (whichever is shorter). At least 14 days must have elapsed between the last dose of investigational agent and the first dose of study drug is administered.
Prior allogeneic or autologous bone marrow transplantation or other solid organ transplantation.
Toxicity from previous anticancer treatment
Invasive malignancy or history of invasive malignancy other than disease under study within the last two years except: Any other invasive malignancy for which the participant was definitively treated, has been disease-free for \<=2 years and in the opinion of the principal investigator and GSK Medical Monitor will not affect the evaluation of the effects of the study treatment on the currently targeted malignancy, may be included in this clinical trial; and curatively treated non-melanoma skin cancer.
Central nervous system (CNS) metastases, with the following exception: • Participants who have previously-treated CNS metastases, are asymptomatic, and have no requirement for steroids at least 14 days prior to first dose of study drug. Participants with carcinomatous meningitis or leptomeningeal spread are excluded regardless of clinical stability.

Replacement therapy (e.g., thyroxine or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
Concurrent medical condition requiring the use of systemic immunosuppressive medications within 7 days before the first dose of study treatment. Physiologic doses of corticosteroids for treatment of endocrinopathies or steroids with minimal systemic absorption, including topical, inhaled, or intranasal corticosteroids may be continued if the participant is on a stable dose.
Condition requiring treatment with strong inhibitors/inducers of cytochrome p (CYP) 450 3A4 within 7 days prior to first dose of chemotherapy (requirement applies to participants enrolled to Part 2 chemotherapy combination with docetaxel).
Active infection requiring systemic therapy, known human immunodeficiency virus infection, or positive test for hepatitis B active infection or hepatitis C active infection.
Current active liver or biliary disease (with the exception of Gilbert's syndrome or asymptomatic gallstones, liver metastases, or otherwise stable chronic liver disease per investigator assessment).
