EIK1005-002: A Clinical Research Study Evaluating EIK1005, a Werner Helicase Inhibitor, as Monotherapy and in Combination With Pembrolizumab in Participants With Advanced Solid Tumors Including Microsatellite Instability High (MSI-H) Tumors

Description

This Phase 1/2 study (EIK1005-002) will investigate the safety and tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary clinical activity of EIK1005 as a monotherapy and in combination with pembrolizumab in participants with advanced solid tumors, including participants with Microsatellite Instability High (MSI-H) or Mismatch Repair Deficient (dMMR) Tumors.

The study will be conducted in 2 parts: Part 1 and Part 2, with Part 1 being further divided into Part 1A and Part 1B as described below:

* Part 1A (monotherapy dose escalation): participants will receive EIK1005 only.
* Part 1B (combination dose escalation): participants will receive EIK1005 in combination with pembrolizumab.
* Part 2 (dose optimization): participants will be randomized 1:1 to monotherapy with EIK1005 at one of the two selected doses from Part 1A to identify the dose of EIK1005 in monotherapy for subsequent studies.
