A Study to Evaluate the Safety and Tolerability of ETC-1922159 as a Single Agent and in Combination With Pembrolizumab in Advanced Solid Tumours

Summary

This is a Phase 1A/B study consisting of four parts. 1. Part A (completed) is a non-randomised, open-label, sequential evaluation of the safety, pharmacokinetics (PK), maximum tolerated dose (MTD), and recommended dose (RD) of ETC-1922159 in patients with advanced or metastatic, or unresectable solid malignancies, for whom no approved treatment option or standard of care is available. Dose escalation, with the goal of identifying the MTD and RD, is guided by an ordinal continual reassessment method (oCRM) model with a cohort size of one patient. 2. Part A extension (completed) is a non-randomised, non-comparative, open-label evaluation of the safety and tolerability of ETC-1922159 together with the bone protective treatment (denosumab) in patients with advanced or metastatic, or unresectable solid malignancies, for whom no approved treatment option or standard of care is available. 3. Part B dose escalation (completed) is a non-randomised, open-label, sequential evaluation of the MTD, RD, safety, PK, and PD (pharmacodynamics) of ETC 1922159 in combination with pembrolizumab in patients with advanced or metastatic, or unresectable solid malignancies, for whom no approved treatment option or standard of care is available. 4. Part B dose expansion will be a non-randomised, non-comparative, open-label study evaluation of the safety and tolerability of ETC-1922159 as a single agent until disease progression and then in combination with pembrolizumab at the RD identified in the Part B dose escalation segment, in patients with advanced or metastatic, or unresectable solid malignancies that are refractory, intolerant or not suitable for available treatment according to the treating physician. It is anticipated that the study will take approximately 78 months to complete (36 months for Part A and Part A Extension, approximately 6 months for Part B dose escalation and approximately 36 months for Part B dose expansion).
