About this study

Official title: A Phase 1, Single-center, Open-label, Non-randomized, Fixed-sequence, Drug-drug Interaction Study to Assess the Effect of Repeated Doses of Intravenous Ceftobiprole on the Pharmacokinetics of Oral Pitavastatin (OATP1B Substrate) and on Plasma Levels of Coproporphyrin I (OATP1B Biomarker) in Healthy Subjects

The goal of this clinical study was to determine the effect of the test drug ceftobiprole (a drug approved for the treatment of bacterial infections) on the elimination of pitavastatin (a drug approved for the treatment of increased levels of cholesterol in blood) from the body. This interaction was investigated by pharmacokinetic (PK) assessments. The clinical study also investigated the safety of ceftobiprole and how well ceftobiprole was tolerated by healthy subjects when it was administered in combination with pitavastatin.

Read the detailed description

This study assessed whether there was an inhibitory effect of ceftobiprole on hepatic organic anion-transporting polypeptide 1B (OATP1B) activity. Pitavastatin was used as an OATP1B substrate in this study. The pharmacokinetics of oral pitavastatin were assessed when administered alone and when administered together with IV ceftobiprole in a study design including 2 treatment periods. In addition, the pharmacodynamic effect of repeated doses of IV ceftobiprole on the diurnal plasma levels of coproporphyrin I (CP-I) was assessed in this study as CP-I is an endogenous biomarker for hepatic OATPB1 activity.

The study duration was up to 38 days.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing pitavastatin and pitavastatin single dose combined with ceftobiprole in people with Drug-drug Interaction Study, run by Basilea Pharmaceutica at 1 site in Netherlands.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 21 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 21 Apr 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Maximum Observed Plasma Concentration (Cmax) of Pitavastatin (time frame: Sampling on Day 1 and Day 6; before dosing, 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12 hours (h) post-dose. Day 2 and Day 7; 24 and 36 h post-dose. Day 3 and Day 8; 48 h post-dose). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Apr 2026.
