COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Description of intervention(s) / exposure
The intervention is LYN-PLT, a modified release (MR) prototype capsule containing inactive ingredients. The rationale for development of this MR formulation is to reduce the frequency of dosing of orally-administered medications to once weekly or less and thereby improving the management of acute and chronic diseases.

The dose of LYN-PLT to be given is a single Size 00EL capsule containing less than 300 mg sucrose within the formulation's MR formulation (stellate). The capsule will be administered once by a trained nurse (at a minimum) in a hospital (Group 1 and Group 2) or clinic (Group 3, Group 4, and Group 5).

There are four arms: Formulation A, Formulation B, Formulation C, and Formulation D with each arm/capsule containing a different type of proprietary stellate.

Participants will be randomised to receive only one of the five study formulations (A-E).

Treatment: Drugs
Comparator / control treatment
Single oral dose of placebo capsule, containing microcrystalline cellulose, (Formulation E) will be delivered. Participants will be randomised to receive only one of the five study formulations (A, B, C, D or E).
Control group

Primary outcome [1] 306115 0
Gastric retention assessed by Magnetic Resonance Imaging (MRI)
Timepoint [1] 306115 0
Days 1, 2, 4, 7 and 9 after dosing
Primary outcome [2] 306116 0
Safety and tolerability of several modified release (MR) capsules and a placebo capsule. Adverse events will be collected from a combination of the following:
1) Spontaneous adverse event reporting
2) Vital signs, physical examinations and pre-dose (Day 1) and post-dosing (Day 4 and 7) safety laboratory assessments (haematology, liver function tests, clinical chemistry panel)
3) Examination of post-dosing bowel movements for blood
4) Use of a systematic algorithm to evaluate abdominal pain, should it occur (including laboratory assessments, physical examination, imaging studies)
Clinically significantly abnormal findings for items 2) through 4) will be reported as adverse events.
Timepoint [2] 306116 0
Adverse events, concomitant medications, vital signs, directed physical examinations will be conducted daily for 8 days during an inpatient admission for observation after dosing. After Day 8, participants will be discharged from the unit and will return for these assessments on Day 10, 15, 22, and 29. Safety laboratory assessments will be performed prior to dosing, at Day 4, and Day 7
Secondary outcome [1] 347605 0
Gastric retention assessed by abdominal ultrasound (U/S)
Timepoint [1] 347605 0
Days 1, 2, 4, 7, 9 after dosing
Secondary outcome [2] 347606 0
Confirm oesophageal clearance of several MR capsules and a placebo capsule.
Timepoint [2] 347606 0
In Group 1 and Group 2, post dosing endoscopy will be performed approximately 2 hours after dosing to confirm oesophageal transit to the stomach.
Secondary outcome [3] 347607 0
To summarise the physical features of the formulation/stellate recovered from collected faecal specimens
Timepoint [3] 347607 0
0, 4, 8, 12, 24, 48, 72, 96, 120, 144 hours.
Day 8, 10, 15, 22
