Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is LYN-057, a modified release (MR) prototype capsule containing memantine hydrochloride (HCl) (50 mg). The rationale for the development of this MR formulation is to reduce the frequency of dosing orally administered memantine HCl medications to once weekly or less and thereby improving the management of Alzheimer's disease.

The dose of LYN-057 to be given is a single Size 00EL capsule containing 50 mg memantine HCl within the MR formulation (stellate). One capsule (50 mg dose) will be administered to the participant. This single capsule dose will be administered by a trained nurse (at a minimum) in a clinic (for Sentinel, Main or, if required, Supplemental Dosing Groups).

Outcomes
Primary outcome [1] 307173 0
Gastric retention assessed by imaging [Magnetic Resonance Imaging (MRI) or abdominal ultrasound (U/S)]
Timepoint [1] 307173 0
Days 1, 2, 4, 7 and 9 after dosing
Primary outcome [2] 307174 0
Safety and tolerability of memantine HCl (50 mg) MR prototype capsule. Adverse events will be collected from a composite/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, coagulation, liver function tests, clinical chemistry panel)
3) Examination of post-dosing bowel movements for blood
4) Use of systematic algorithm to evaluate moderate or severe abdominal pain, should it occur (including laboratory assessments, physical examination, imaging studies)
Timepoint [2] 307174 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] 350975 0
Memantine HCl pharmacokinetics [Cmax, Tmax, AUC (0-t)] by validated assay,
Timepoint [1] 350975 0
Pre-dose, on day of dosing at 2, 4, 6, 8, and 12 hours post dosing, thereafter daily during inpatient admission through Day. After Day 8, participants will be discharged from the unit and will return for PK/blood sampling on Day 10, 15, 22 and 29.
Secondary outcome [2] 350976 0
As an exploratory outcome, to summarise the physical features of the formulation/stellate recovered from collected faecal specimens, e.g., full vs. partial stellate vs. core only vs. arms only
Timepoint [2] 350976 0
Post-dosing
2, 4, 8, 12, 24, 48, 72, 96, 144 hours
Day 8, 10, 15, 22
