Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To assess how long extended release prototype capsule formulations stay in the stomach as determined by magnetic resonance imaging (MRI).

To evaluate the safety of several extended release capsule formulations (LYN-PLT) and a placebo capsule.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a multicentre, observer blind, randomised, single dose study in healthy adult subjects.

The first 5 subjects enrolled into the study will be regarded as Dosing Group 1 (sentinel group) and assigned to each of the five available study formulations. Dosing of subjects in Dosing Groups 1 and 2 will be performed at the endoscopy centre. Dosing of subjects in Dosing Groups 3 through 5 will be performed at the clinical site.

Subjects remain in the inpatient unit for 7 days after dosing. During this time, subjects undergo intermittent imaging assessments for gastric retention (MRI and abdominal U/S), safety assessments and faecal collections for assessments of retrieved components and bowel movement characteristics.

Subjects return to the clinic on Days 10, 15, 22 and 29 (End of Study visit). Safety assessments will be performed at all visits. MRI, abdominal U/S and outpatient faecal collections may continue based on the clinical findings from subjects dosed with modified release capsule formulations. On Day 29, the subjects will undergo final safety assessments at the clinic and thereafter, will be discharged from the study.

Allocation Method

RANDOMIZED

Intervention Model

FACTORIAL

A total of 40 eligible subjects participate in the Dosing and Observation period. The enrollment occurs in five Dosing Groups. Within each Dosing Group, subjects are randomized to receive either one of four LYN-PLT extended release capsules or a placebo capsule (8 per formulation).
