Due to the exploratory nature of this trial, there is no primary objective in a confirmatory sense. The study aims

- to evaluate the effect of different doses of BI 409306 on biomarker and to assess the exposure of BI 409306

Condition Intervention Phase
Healthy Drug: BI 409306 Drug: BI 409306 Placebo Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double
Primary Purpose: Treatment
Official Title: Randomised, Double-blind, Placebo-controlled Parallel-group Proof of Mechanism Study to Assess the Pharmacokinetics and to Evaluate the Pharmacodynamic Effect of Different Single Oral Doses of BI 409306 in Healthy Male Volunteers

Further study details as provided by Boehringer Ingelheim:

Primary Outcome Measures:
  • Maximum change from baseline (calculated as ratio) of biomarker [ Time Frame: up to 12 weeks ]
  • Cmax ratio of BI 409306 in different media [ Time Frame: up to 12 weeks ]

Secondary Outcome Measures:
  • Maximum measured biomarker concentration [ Time Frame: up to 12 weeks ]
  • Time from dosing to maximum measured in biomarker concentration [ Time Frame: up to 12 weeks ]
