Study Details

Study Description

Brief Summary

The purpose of this study is to evaluate the safety and tolerability of ascending doses of the MEK-inhibitor zapnometinib (ATR-002) given as single doses (SAD Part) and as multiple doses for 7 days (MAD Part) in healthy subjects.

Condition or Disease Intervention/Treatment Phase
Phase 1

Detailed Description

This is a Phase 1, single-center, randomized, double-blind, controlled clinical trial (zapnometinib vs. placebo in the SAD/MAD Parts; 'fed' vs. 'fasted' in the FDI Part, 'probe substance' (repaglinide or celecoxib) in combination with zapnometinib vs. probe substance alone in the DDI part). The study will assess the safety, tolerability, PK and PD effects of zapnometinib versus a matching placebo (applicable to SAD/MAD Part) in healthy subjects. The FDI cohorts will investigate the possible impact of a standard breakfast high in fat content in comparison to administration in fasted state. The DDI cohorts with celecoxib and repaglinide will investigate a possible drug-drug interaction.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Experimental: ATR-002

In the SAD part, study participants will receive IMP orally once (except for the first cohort), or twice (two single doses separated by an adequate washout period of at least 10 days for the FDI cohort, which will be conducted according to a two-period fixed-sequence design with all subjects receiving the treatment sequence 'fasted-fed'). In each of the periods of the MAD Part, study participants will receive the IMP for seven consecutive days. Dosing will start at 600 mg in the first cohort and follow the dose escalation schedule that is given in the study protocol.
