A Phase 1 Study to Evaluate EMP22 PD and EMP16 PK Versus Xenical® in Healthy Volunteers
Study Details
Study Description
Brief Summary
This Phase I, active-controlled, randomised trial will be conducted in 2 parts. Part I aims to confirm the PD equivalence of EMP22 and Xenical® based on percent fecal fat excretion at steady state. EMP22 (also referred to as MR orlistat) has the same MR properties as EMP16 but lacks the acarbose component. Part II will explore the PK properties of EMP16 alone and vs. Xenical®. Part I will be conducted in a single-blind, cross-over fashion while Part II will have an open-label, fixed-sequence design. Healthy volunteers will be recruited to the trial.

Phase 1 |
Detailed Description
Approximately 35 participants are planned to be screened to achieve 20 randomised participants and at least 16 evaluable participants in Part I.
All participants who complete Part I will continue in Part II.
Each participant is expected to participate in the trial for approximately 9 to 13 weeks (depending on the length of each wash-out period), including a 28-day screening period.
Part I: Participants will self-administer EMP22 for 9 days and Xenical® for 9 days (TID dosing) at home. EMP22 and Xenical® should be taken halfway through each of the 3 main meals during the day (breakfast, lunch, dinner) with approximately 50 to 200 mL water.
EMP22 and Xenical® have different strengths of orlistat, 60 mg and 120 mg, respectively. In order to maintain the blind for the participants, the IMP will be administered as follows:
-
EMP22 60 mg orlistat, 2 capsules TID.
-
Xenical® 120 mg orlistat 1 capsule + placebo 1 capsule TID.
Part II: Following an overnight fast of at least 8 hours and a light standardised breakfast upon admission (approximately 2 hours prior to dose), EMP16 will be taken halfway through a regular standardised breakfast (5 minutes after the start of the meal, which is expected to be finished in 10 minutes) with approximately 50 to 200 mL water. After a 4-14 day washout, the same procedure will be repeated using Xenical® .
The participants will receive a single dose dose of EMP16 (2 capsules, each of 60 mg) and a single dose of Xenical® (1 capsule, 120 mg).

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Xenical - EMP22 part 1 crossover blinded After a 5-day diet run-in period, orlistat in its conventional form (Xenical®, 120 mg orlistat) will be taken 3 times daily (ter in die [TID]) together with the 3 main daily meals for a 9-day treatment period. After a 4-to-14-day wash-out period; EMP22 (120 mg modified release orlistat) will be taken TID together with the 3 main daily meals for a 9-day treatment period. |
Drug: Xenical® vs EMP 22
Each participant will first use Xenical® TID for 9 days and then EMP22TID for 9 days (in total 27 doses of each drug).

Outcome Measures
Primary Outcome Measures
- The percent of faecal fat [Day -2 , Day -1 , and between the morning of Day 9 and Day 10.]
The percent of faecal fat excretion expressed as a ratio of the amount of fat excretion over a 24-hour period at steady-state relative to the amount of daily ingested fat.
Secondary Outcome Measures
- Cmax - to explore the PK properties of EMP16 [12 hour for each day of treatment]
Cmax for orlistat and acarbose
- Tmax - to explore the PK properties of EMP16 [12 hour for each day of treatment]
Tmax for orlistat and acarbose
- AUC0-t - to explore the PK properties of EMP16 [12 hour for each day of treatment]
AUC0-t for orlistat and acarbose
- Cmax - to compare the bioavailability of orlistat in EMP16 and Xenical® [12 hour for each day of treatment]
Cmax for orlistat
- Tmax - to compare the bioavailability of orlistat in EMP16 and Xenical® [12 hour for each day of treatment]
Tmax for orlistat
- AUC0-t - to compare the bioavailability of orlistat in EMP16 and Xenical® [12 hour for each day of treatment]
AUC0-t for orlistat
