Who may be able to join
- Subject must be >=18 years of at the time of signing the informed consent.

GSK1795091 is being developed for administration in combination with other immune system modulators for the treatment of cancers. The study will be conducted in two parts. In Part 1, dose escalation will be performed to identify combination dose levels comprising GSK1795091 with either 24 milligrams (mg) GSK3174998 (Part 1a), 80 mg GSK3359609 (Part 1b), or 200 mg pembrolizumab (Part 1c). One dose level of GSK3174998, GSK3359609, or pembrolizumab with up to 5 dose levels of GSK1795091 are planned for evaluation. In Part 2 (dose-expansion), subjects will receive a single dose level of GSK1795091 as identified based on data from Part 1, in combination with either GSK3174998, GSK3359609, or pembrolizumab.

Measured: Up to 2 years
Part 2: Number of Participants With TEAEs Leading to Dose Reductions or Dose Delays
An adverse event is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study treatment, whether or not considered related to the study treatment. TEAEs are defined as adverse events that started or worsened in severity on or after the first dose of study medication.
Measured: Up to 2 years
Part 1: Number of Participants With Change From Baseline in Hematology Parameters With Respect to the Normal Range
Blood samples were collected for the analysis of following hematology parameters: neutrophils (Neutro), lymphocytes (lympho), monocytes (Mono), eosinophils (Eosino), basophils (Baso), hemoglobin (Hb), hematocrit (Hct), erythrocytes (Erythro), erythrocyte mean corpuscular volume (EMCV), erythrocyte mean corpuscular hemoglobin (EMCH) and platelet count (PC). Baseline value was the latest pre-dose assessment with a non-missing value, including those from unscheduled visits. Data was categorized as decrease to low (D to L) (value below lower limit of normal range [LNR]) and increase to high (I to H) (value above upper LNR). Participants were counted twice if participant had both decreased to low and increased to high within an assessment. Data for worst-case on therapy for categories decrease to low and increase to high is presented.
Measured: Baseline (Day 1: Pre-dose) and up to 2 years
Part 2: Number of Participants With Change From Baseline in Hematology Parameters With Respect to the Normal Range
Blood samples were planned to be collected for the analysis of following hematology parameters: neutrophils, lymphocytes, monocytes, eosinophils, basophils, hemoglobin, hematocrit, erythrocytes, erythrocyte mean corpuscular volume, erythrocyte mean corpuscular hemoglobin and platelet count.
Measured: Baseline (Day 1: Pre-dose) and up to 2 years
Part 1: Number of Participants With Change From Baseline in Chemistry Parameters With Respect to the Normal Range
Blood samples were collected for the analysis of following chemistry parameters: urea, creatinine (Cr), glucose (Glu), potassium (Pot), sodium (Sod), calcium (Cal), aspartate aminotransferase (AST), ALT, alkaline phosphatase (ALP), bilirubin (Bil), direct bilirubin (D.Bil), protein, albumin (Alb), C-reactive protein (CRP) and Creatinine Clearance (CrCl). Baseline value was the latest pre-dose assessment with a non-missing value, including those from unscheduled visits. Data was categorized as decrease to low (value below the lower LNR), and increase to high (value above the upper LNR). Participants were counted twice if the participant had both decreased to low and increased to high within an assessment. Data for worst case on therapy for categories decrease to low and increase to high is presented.
Measured: Baseline (Day 1: Pre-dose) and up to 2 years
Part 2: Number of Participants With Change From Baseline in Chemistry Parameters With Respect to the Normal Range
Blood samples were planned to be collected for the analysis of following chemistry parameters: urea, creatinine, glucose, potassium, sodium, calcium, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, bilirubin, direct bilirubin, protein, albumin, C-reactive protein and Creatinine Clearance.
Measured: Baseline (Day 1: Pre-dose) and up to 2 years
Part 1: Number of Participants With Worst Case Urinalysis Results Relative to Normal Range Criteria
Urine samples were collected for the analysis of following urinalysis parameters: glucose (Glu), protein (Pro), occult blood (OB), ketones, potential of hydrogen (pH) and specific gravity (SpGr) by dipstick method. The dipstick test gives results in a semi-quantitative manner. Urine specific gravity is a measure of the concentration of solutes in the urine and provides information on the kidney's ability to concentrate urine. The reference range is 1.002-1.030. Urine pH is an acid-base measurement. Normal urine has a slightly acid pH (5.0 - 6.0). Data was categorized as decrease to low (value below the lower LNR) and increase to high (value above the upper LNR). Participants were counted twice if the participant had both decreased to low and increased to high within an assessment. Data for worst-case on therapy for categories decrease to low and increase to high is presented.
Measured: Up to 2 years
Part 2: Number of Participants With Worst Case Urinalysis Results Relative to Normal Range Criteria

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
GSK1795091 is being developed for administration in combination with other immune system modulators for the treatment of cancers. The study will be conducted in two parts. In Part 1, dose escalation will be performed to identify combination dose levels comprising GSK1795091 with either 24 milligrams (mg) GSK3174998 (Part 1a), 80 mg GSK3359609 (Part 1b), or 200 mg pembrolizumab (Part 1c). One dose level of GSK3174998, GSK3359609, or pembrolizumab with up to 5 dose levels of GSK1795091 are planned for evaluation. In Part 2 (dose-expansion), subjects will receive a single dose level of GSK1795091 as identified based on data from Part 1, in combination with either GSK3174998, GSK3359609, or pembrolizumab.
