• Status: Completed
• Trial end date: 2021-03-23
• Target enrollment: 0
• Participant gender: All

Summary

The pharmacokinetics of fluconazole are expected to be different in obese patients compared to non-obese patients. The investigators will determine fluconazole and free fluconazole concentrations in 16 obese patients and 8 healthy volunteers, who will receive oral and intravenous fluconazole in a semi-simultaneous design.

A full pharmacokinetic curve will be obtained until 48 hours after intravenous administration.

• Phase: Phase 4
• Accepts Healthy Volunteers?: Accepts Healthy Volunteers

Criteria

Inclusion Criteria:

1. Subjects BMI:

1. obese groups: subject must have a BMI ≥35 kg/m2 at the time of inclusion or has undergone bariatric surgery;

2. non-obese group: subject must have a BMI ≥18.5 and <30 kg/m2 at the time of inclusion;

2. Subject is at least 18 of age on the day of screening and not older than 65 years of age on the day of dosing;

3. Subject able and willing to sign the Informed Consent before screening evaluations.

4. If a woman, is neither pregnant nor able to become pregnant and is not nursing an infant.

For the non-obese subjects the following additional inclusion criteria applies:

5. Subject is in good age-appropriate health condition as established by medical history, physical examination, electrocardiography, results of biochemistry and hematology within 6 weeks prior to study drug administration. Results of biochemistry and hematology should be within the laboratory's reference ranges (see Appendix A). If laboratory results are not within the reference ranges, the subject is included based on the investigator's judgment that the observed deviations are not clinically relevant. This should be clearly recorded.

Exclusion Criteria:

1. Documented history of sensitivity to fluconazole or similar azole-compound;

2. Documented history of the long QT syndrome (LQTS);

3. History of, or known abuse of drugs, alcohol or solvents (up until a maximum of three months before study drug administration);

4. Use of medication that has known relevant interaction with study drug as determined by the investigator up to 1 weeks prior to study drug administration;

5. Donation of blood or plasma to a blood bank or in a clinical study (except a screening visit) within 4 weeks prior to study drug administration;

6. Blood transfusion within 8 weeks prior to study drug administration;

7. Treatment with the concerning study drug up to 7 days before administration of the study drug;

8. Any other sound medical, psychiatric and/or social reason as determined by the investigator.
