Summary

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.

Detailed description

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.

Interventions

Type	Name	Description
DRUG	GSK3145095	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.
DRUG	Pembrolizumab	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).
