Relative Bioavailability Study of Emodepside IR-tablets and Solution
Phase1,Randomized,Open-Label,Parallel-Group,Relative Bioavailability Study to Investigate PK,Including Food Effect,Safety and Tolerability of Single Doses of New Immediate Release Tablet Formulations of Emodepside (BAY 44-4400),Compared to Oral Solution,in Healthy Male Subjects
Study Overview
Detailed Description
There is an urgent need for a macrofilaricidal drug, killing or sterilizing permanently O. volvulus adult worms, which could be used in individual case management and, after appropriate testing, as an alternative drug to ivermectin in MDA programs. Emodepside is a promising candidate to kill the adult and sexually mature O. volvulus. Emodepside was shown to be macrofilaricidal against a variety of filarial nematodes and is a registered drug for animal health, commercialized by Bayer AG under the name of Profender® (in combination with praziquantel) or Procox® (in combination with toltrazuril).
A first-in-human (FIH) double-blind, placebo-controlled study of single ascending doses of emodepside in healthy Caucasian men has been conducted and the preliminary results are favourable, and support continuing the Phase I development program. For this reason, new tablet formulations have been developped and the present study will evaluate bioavailability, PK safety and tolerability, and as well food effect of single doses of 2 new immediate release (IR)-tablet formulations of emodepside compared to the oral liquid service formulation (LSF) used in the FIH study.

Exclusion Criteria:
- Administration of a licensed or unlicensed medicinal product as part of another clinical trial in the 3 months before the first dose of study medication, or within 5 half-lives of administration of a medicinal product given in the previous study (whichever is longer), or otherwise in the follow-up period for any clinical trial
- Clinically relevant abnormal medical history, concurrent medical condition, acute or chronic illness, or history of chronic illness (such as diabetes mellitus or other abnormalities of glucose homeostasis) sufficient to invalidate the subject's participation in the trial or make it unnecessarily hazardous

- History of a severe allergy, non-allergic drug reaction, severe adverse reaction to any drug, or multiple drug allergies
- Hypersensitivity to any ingredient of the study medication, including the active ingredient (emodepside)
- Presence or history of drug or alcohol abuse in the last year, or intake of more than 21 units (1 unit = 1/2 pint of beer, 1 small glass of wine or 1 measure of spirits) of alcohol weekly
- Regular daily consumption of more than one litre of beverages containing xanthine

- Use, within 14 days before the dose of study medication, of dietary supplements or herbal remedies (such as St John's Wort) that are known to be inducers or inhibitors of CYP3A4, or other co-medications known to be relevant substrates of CYP3A4 (see list in the Study Procedures Manual)
- Use, within 14 days before the dose of study medication, of dietary supplements or herbal remedies that are known to be strong inhibitors of P-gp, or other co-medications known to be relevant substrates of P-gp (see list in the Study Procedures Manual)
Relevant pathological abnormalities in the ECG at screening, such as:
second or third-degree atrioventricular (AV) block prolongation of the QRS complex > 120 msec, QTc-interval (QTcB or QTcF) > 450 msec. The mean of the triplicate ECG readings will be used to assess eligibility.
- Evidence of drug abuse (via urine testing) at the screening assessment or admission to the ward
- Use of excluded therapies that may impact on the interpretation of study results in the opinion of the Investigator or Sponsor
- Objection by General Practitioner (GP) to subject entering trial
- History of residing for 6 or more continuous months during the last 3 years in regions with endemic parasitic infections, as determined by the Investigator
- Possibility that subject will not cooperate with the requirements of the protocol
