In Part 1, advanced or metastatic PDAC will be enrolled. Part 1 will be using escalating doses of GSK3145095 (total daily dose of 100 mg, 200 mg, 400 mg, 800 mg, and 1600 mg) orally as monotherapy for up to 2 years. For each dose level, subjects will receive a single dose of half the total daily dose on Day 1; and as BID (total daily dose divided in two equal doses) starting from Day 2.

In Part 2, subjects with selected solid tumors, including but not limited to, PDAC, NSCLC, TNBC and/or melanoma will be enrolled. Part 2 will be using GSK3145095 combination escalation to start at least one dose level below the highest dose of GSK3145095 shown to be safe in Part 1, orally BID for up to 2 years along with pembrolizumab 200 mg intravenous (IV) every 3 weeks (Q3W) for up to 2 years.

In Part 3, subjects with selected solid tumors will be enrolled. Part 3 will be using GSK3145095 at one or two dose levels shown to be tolerable in Part 2 orally BID for up to 2 years along with pembrolizumab 200 mg IV Q3W for up to 2 years.

In Part 4, subjects with selected solid tumors will be enrolled. Part 4 will be using GSK3145095 at one or two dose levels shown to be tolerable in Part 2 orally BID for up to 2 years along with combination of additional anticancer agents.

GSK3145095 will be available as capsule (size 1 containing 5 to 25 mg GSK3145095 and size 0 containing 25 to 75 mg GSK3145095) or tablet (25, 50, 200 mg white to slightly covered round/oval shaped coated) for oral administration in the fasted stated with approximately 200 milliliters (mL) of water.

GSK3145095

Pembrolizumab will be available as solution for infusion (100 milligrams/ 4 milliliter) at a dose of 200 mg via IV infusion for 30 minutes (given the variability of infusion pumps from site to site, a window of -5 minutes and +10 minutes is permitted i.e., infusion time is 25 to 40 minutes).

GSK Clinical Trials

In an unbiased CRISPR screen, RIPK1 was identified as a top gene contributing to immunotherapy resistance. In addition, RIPK1 has been reported to drive pancreatic oncogenesis. In murine models, inhibition of RIPK1 kinase activity in the pancreatic tumor microenvironment leads to the replacement of tumor-permissive myeloid infiltrates with innate cells that promote an effective antitumor response by adaptive cells. The investigators hypothesize that inhibition of RIPK1 in human pancreatic cancer subjects will modulate the immune infiltrate to sensitize tumors to checkpoint blockade.

Study 205013 is a Phase 1 FTIH study of GSK3145095 alone and in combination with other anticancer agents including pembrolizumab in subjects with pancreatic ductal adenocarcinoma (PDAC) and other selected tumors. The study includes up to 4 parts: Part 1 dose escalation will be conducted in approximately 30 adult subjects with advanced or metastatic PDAC using escalating doses of GSK3145095 as monotherapy only. Part 2 will combine escalating doses of GSK3145095 with 200 milligram (mg) pembrolizumab. Dose escalation of GSK3145095 will begin at least one level below the highest dose shown to have an acceptable toxicity profile in at least 3 subjects in Part 1. Part 2 may be conducted in a broader population of selected solid tumors using a combination of escalating doses of GSK3145095 and 200 mg pembrolizumab. Part 3 will enroll subjects treated with one or more dose levels of GSK3145095 in combination with 200 mg pembrolizumab. Part 4 will investigate the combination of additional anticancer agents with one or more doses of GSK3145095 identified as safe in Part 1. Up to approximately 220 subjects will be treated in the study. Parts 1 and 2 will each treat up to approximately 30 subjects. Parts 3 and 4 will treat up to approximately 160 subjects (up to 80 subjects in each Part). The total duration of the study is expected to last up to 2 years.

Part 1 dose escalation will administer escalating doses of GSK3145095 as monotherapy only. Part 2 will combine escalating doses of GSK3145095 with 200 mg pembrolizumab. Dose escalation of GSK3145095 will begin at least one level below the highest dose shown to have an acceptable toxicity profile in at least 3 subjects in Part 1.

First-time-in-human (FTIH) Study of GSK3145095 Alone and in Combination With Other Anticancer Agents in Adults With Advanced Solid Tumors

A Phase I/II, Open-Label Study to Investigate the Safety, Clinical Activity, Pharmacokinetics, and Pharmacodynamics of GSK3145095 Administered Alone and in Combination With Anticancer Agents Including Pembrolizumab in Adult Participants With Selected Advanced Solid Tumors

IPD for this study will be made available via the Clinical Study Data Request site.

An AE 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. SAE is defined as any untoward medical occurrence that, at any dose which results in death, is life-threatening, requires in-patient hospitalization or prolongation of existing hospitalization, results in persistent disability/incapacity, is a congenital anomaly/birth defect or other situations.

All adverse events were analyzed using National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) Version 5.0. Graded from Grade 1: mild asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated, Grade 2: Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental activities of daily living (ADL), Grade 3: Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self care ADL, Grade 4: Life-threatening consequences; urgent intervention indicated, Grade 5: death related AE. Higher grade indicates more severe condition. Number of participants with maximum severity grades were presented.

All adverse events were to be analyzed using NCI-CTCAE Version 5.0. Graded from Grade 1: mild asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated, Grade 2: Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental ADL, Grade 3: Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self care ADL, Grade 4: Life-threatening consequences; urgent intervention indicated, Grade 5: death related AE. Higher grade indicates more severe condition.

All toxicities were graded using NCI-CTCAE version 5.0. An AE was considered a DLT if it occurred during the first 28 days of treatment, was considered by the investigator to be clinically relevant, and met one of the following DLT criteria: hematologic toxicity: Grade 4 neutropenia, febrile neutropenia, Grade 4 anemia, Grade 3 thrombocytopenia, Grade 3 thrombocytopenia with bleeding; Grade 3 or greater non-hematologic toxicity, any Grade 2 ocular toxicity requiring systemic steroids.

A participant's disease status and determination of disease progression at post Baseline visits was to be evaluated by the local investigator's assessments by RECIST version 1.1. The overall response rate (ORR)-CR and PR was to be determined by the investigator assessment of the participants computed tomography (CT) or magnetic resonance imaging (MRI) using RECIST version 1.1 criteria for target lesions. ORR is defined as the percentage of participants with a best overall confirmed CR or PR at any time as per disease-specific criteria. PR is when there is at least 30 percent decrease in sum of the longest diameter of the target lesions. Complete Response is when there is disappearance of all non-nodal target lesions, with the short axes of any target lymph nodes reduced to \<10 millimeters (mm).

A participant's disease status and determination of disease progression at post Baseline visits was to be evaluated by the local investigator's assessments by RECIST version 1.1. The overall response rate (complete response and partial response) was to be determined by the investigator assessment of the participants CT or MRI using RECIST version 1.1 criteria for target lesions. ORR is defined as the percentage of participants with a best overall confirmed CR or PR at any time as per disease-specific criteria. Partial Response is when there is at least 30 percent decrease in sum of the longest diameter of the target lesions. Complete Response is when there is disappearance of all non-nodal target lesions, with the short axes of any target lymph nodes reduced to \<10 mm.

Best overall response is defined as the best unconfirmed response (Complete Response \[CR\] \> Partial Response \[PR\] \> Stable Disease \[SD\] \[or non-CR/non-PD\] \> Progressive Disease \[PD\] \> Not Evaluable \[NE\]) from treatment start date until disease progression or initiation of new anti-cancer therapy, whichever is earlier, as assessed by the investigator per RECIST version 1.1 Criteria. The BOR rate is defined as the percentage of participants with each best unconfirmed response category. Participants with unknown or missing responses were treated as non-responders, i.e., these participants were included in the denominator when calculating percentages of response.

Best overall response is defined as the best unconfirmed response (CR \> PR \> SD \[or non-CR/non-PD\] \> PD\] \> NE) from treatment start date until disease progression or initiation of new anti-cancer therapy, whichever is earlier, as assessed by the investigator per RECIST 1.1 Criteria. The BOR rate is defined as the percentage of participants with each best unconfirmed response category. Participants with unknown or missing responses were treated as non-responders, i.e., these participants were included in the denominator when calculating percentages of response.

PFS is defined as time from the date of first dose to the date of disease progression according to clinical or radiological assessment or death due to any causes, whichever occurs earliest. If the participant received subsequent anti-cancer therapy prior to the date of documented events, PFS was to be censored at the last adequate assessment (e.g., assessment where visit level response is confirmed response, partial response or stable disease) prior to the initiation of therapy. Otherwise, if the participant did not have a documented date of event, PFS was to be censored at the date of the last adequate assessment.

Overall survival is defined as time from the date of first dose to the date of death due to any cause. If a participant does not have a documented date of death, time of death is censored at the date of last contact.

All adverse events were planned to be analyzed using NCI-CTCAE Version 5.0. Graded from Grade 1: mild asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated, Grade 2: Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental ADL, Grade 3: Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self care ADL, Grade 4: Life-threatening consequences; urgent intervention indicated, Grade 5: death related AE. Higher grade indicates more severe condition.
