June 15, 2026 updated by: Boehringer Ingelheim

Safety, Tolerability and Pharmacokinetics of Single and Multiple Oral Doses of BI 3031185 in Japanese Healthy Male Trial Participants (Single-blind, Randomised, Placebo-controlled, Parallel Group Design) and Effect of Multiple Doses of BI 3031185 on Pharmacokinetics of a Single Dose of a Combination of Drospirenone and Ethinylestradiol (Oral Contraceptive) in Japanese Healthy Female Trial Participants (Non-randomised, Open-label, Fixed Sequence Design)

Single dose (SD) part: The main objectives of this trial are to investigate safety, tolerability and pharmacokinetics (PK) of BI 3031185 in healthy male trial participants following oral administration of single dose.

Multiple doses (MD) part: The main objectives of this trial are to investigate safety, tolerability and pharmacokinetics (PK) of BI 3031185 in healthy male trial participants following oral administration of multiple doses.

Oral contraceptives (OC) part: The main objective of this trial is to investigate the effect of multiple oral doses of BI 3031185 on pharmacokinetics of drospirenone (DRSP) and ethinylestradiol (EE) (YAZ®) in Japanese healthy female trial participants.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

NO

IPD Plan Description

Clinical studies sponsored by Boehringer Ingelheim, phases I to IV, interventional and non-interventional, are in scope for sharing of the raw clinical study data and clinical study documents. Exceptions might apply, e.g. studies in products where Boehringer Ingelheim is not the license holder; studies regarding pharmaceutical formulations and associated analytical methods, and studies pertinent to pharmacokinetics using human biomaterials; studies conducted in a single center or targeting rare diseases (in case of low number of patients and therefore limitations with anonymization).
