Trial overview

Official title: A Phase I, Open-Label Study of GSK3174998 Administered Alone and in Combination with Anticancer Agents including Pembrolizumab in Subjects with Selected Advanced Solid Tumors
Trial description: This is a first time in human (FTIH), open-label, non-randomized, multicenter study designed to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics, and preliminary clinical activity of GSK3174998 administered intravenously to participants with selected advanced or recurrent solid tumors. This dose-escalation study will assess the safety, activity of GSK3174998 as monotherapy (Part 1), in combination with pembrolizumab (Part 2), and potentially in combination with additional therapies.
The study will be conducted in 2 parts, each part consisting of starting with a dose-escalation phase followed by a cohort expansion phase. GSK3174998 will first be evaluated as monotherapy in escalating doses. Once a dose of GSK3174998 has been identified that is both tolerable and demonstrates pharmacodynamic activity, enrollment of Part 2 may begin. In Part 2, escalating doses of GSK3174998 will be evaluated with fixed doses of pembrolizumab.
The maximum duration of treatment with GSK3174998 and pembrolizumab will be approximately 2 years or 35 cycles, whichever comes first. The follow-up period for safety assessments will be a minimum of 3 months from the date of the last dose. The post-treatment follow-up period will include disease assessments every 12 weeks until documented progressive disease (PD). Approximately 141 participants with selected advanced or recurrent solid tumors will be enrolled.

  • Provide signed, written informed consent.
  • Male and female participants, age >=18 years (at the time consent is obtained).
  • Prior treatment with the following agents (from last dose of prior treatment to first dose of GSK3174998): Tumor necrosis factor receptor (TNFR) agonists, including OX40, CD27, CD137 (4-1BB), CD357 (GITR): at any time; Checkpoint inhibitors, including Programmed death receptor-1 (PD-1),
  • 1, and cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) inhibitors: within 4 weeks; other anticancer therapy, including chemotherapy, targeted therapy, and biological therapy: within 4 weeks or 5 half lives of the drug, whichever is shorter. Prior radiation therapy is permissible if at least one unirradiated measurable lesion is available for assessment via RECIST version 1.1. A wash out of at least two weeks before start of study drug for palliative radiation to the extremities for osseous bone metastases and 4 weeks for radiation to the chest, brain, or visceral organs is required; Investigational therapy: if the participant has participated in a clinical trial and has received an investigational product: within 30 days or 5 half-lives of the investigational product (whichever is shorter). At least 14 days must have passed between the last dose of prior investigational agent and the first dose of study drug.
