This Study Tests the Effect of Certain Medicines on the Transport of Other Medicines in the Body of Healthy Men

The Effect of Potent Inhibitors of Drug Transporters (Verapamil, Rifampin, Cimetidine, Probenecid) on Pharmacokinetics of a Transporter Probe Drug Cocktail Consisting of Digoxin, Furosemide, Metformin and Rosuvastatin (an Open-label, Randomised, Crossover Trial in Three Parts)

The primary objective of this trial is to investigate the relative bioavailabilities of digoxin, furosemide, metformin and rosuvastatin given as a cocktail alone and as a cocktail together with the following drug transporter inhibitors:

Part 1: verapamil (P-gp) and rifampin (OATP1B1/1B3) Part 2: cimetidine (OCT2/MATE) Part 3: probenecid (OAT1/3) The secondary objective is to investigate other potential changes in pharmacokinetics (e.g. in clearance, volume of distribution, etc.) of digoxin, furosemide, metformin and rosuvastatin given as a cocktail alone and as a cocktail together with the inhibitors describe above.

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).
