Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is LYN-157, a extended release (ER) prototype capsule containing memantine hydrochloride (HCl) (40 mg) and donepezil HCl (38 mg). The rationale for the development of this ER formulation is to reduce the frequency of dosing orally administered memantine and donepezil HCl medications to once weekly or less and thereby improving the management of Alzheimer's disease.
The dose of LYN-157 to be given is a single Size 00EL capsule containing 40 mg memantine HCl and 38 mg donepezil HCl within the ER formulation (stellate). One capsule will be administered to the participant. This single capsule dose will be administered by a trained nurse (at a minimum) in a clinic for both Sentinel and Main, if required, dropouts will be replaced at the discretion of the PI.

Outcomes
Primary outcome [1] 319690 0
Safety and tolerability of a LYN-157 capsule containing memantine hydrochloride and donepezil hydrochloride assessed from a combination of the following: adverse event (AE’s) reporting, tracking of concomitant medications and examinations specified per protocol, e.g., safety laboratory tests, physical examinations, vital signs, ECGs, inspection of faeces for gross blood.
Timepoint [1] 319690 0
Adverse events and vital signs will be conducted daily for 8 days during an inpatient admission for observation after dosing. Directed physical exams will be performed at admission and on Days 1, 4, 8 and at the follow-up visits on Days 10, 15, 22 and 29 (End of Study). ECGs and safety laboratory assessments will be performed at admission and Days 4 and 7. Concomitant medications will be tracked at admission (Day -1), discharge from the unit (Day8) and at follow-up visits on Days 10, 15, 22 and 29 (End of study).
Primary outcome [2] 319691 0
Memantine pharmacokinetics [Cmax, Tmax, AUC(0-t)] by validated assay
Timepoint [2] 319691 0
Pre-dose, on day of dosing at 2, 4, 6, 8 and 12 hours post dosing, thereafter daily during inpatient admission through Day 8. After Day 8, participants will be discharged from the unit and will return for PK/blood sampling on Days 10, 15, 22 and 29 (End of Study).
Primary outcome [3] 319692 0
Donepezil pharmacokinetics [Cmax, Tmax, AUC(0-t)] by validated assay
Timepoint [3] 319692 0
Pre-dose, on day of dosing at 2, 4, 6, 8 and 12 hours post dosing, thereafter daily during inpatient admission through Day 8. After Day 8, participants will be discharged from the unit and will return for PK/blood sampling on Days 10, 15, 22 and 29 (End of Study).
Secondary outcome [1] 369192 0
Gastrointestinal transit of LYN-157 capsules by imaging [MRI or X-ray] assessments
Timepoint [1] 369192 0
Day 2 (Sentinel subjects only X-ray), MRI: Days 3, 5, 8; X-ray: Day 22, if required, i.e., if formulation components have not been retrieved by the time of discharge.
