Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is LYN-005, a single extended release (ER) capsule containing risperidone (14 mg). The rationale for the development of this ER capsule is to reduce the frequency of dosing orally administered risperidone medications to once weekly or less and thereby improving the management of schizophrenia.
LYN-005, to be administered, is a single Size 00EL capsule, containing 14 mg risperidone (a proposed weekly dose), within the ER formulation (stellate).
While inpatient, on Day -3 to Day -1, a 2 mg RISPERDAL IR tablet will be orally administered daily to each participant.
On Day 1 (no Day 0), one LYN-005 capsule will be orally administered to the participant. The single capsule will be administered by a trained nurse (at a minimum) in a clinic for the Sentinel (first participant) and Main (remaining participant) groups. If required, dropouts will be replaced at the discretion of the PI.
On Day 8 while still within the inpatient facility, participants will return to their daily outpatient RISPERDAL administration until discharge (Day 12).

Outcomes
Primary outcome [1] 321665 0
Safety and tolerability of a LYN-005 ER capsule assessed from a combination of the following:
- Incidence and severity of adverse events (AEs) and serious adverse events (SAEs), treatment-related and treatment emergent AEs, AEs leading to withdrawal, AEs of Special Interest (AESI), death, concomitant medications, safety laboratory tests, physical examinations, vital signs and electrocardiograms (ECGs).
and
- Extrapyramidal Symptom Rating Scale (ESRS), assessment of global function Clinical Global Impression-Severity (CGI-S), suicidality using the Columbia-Suicide Severity Rating Scale (C-SSRS)
Timepoint [1] 321665 0
Adverse events and vital signs will be conducted daily for the duration an inpatient admission for observation after dosing, at discharge and on follow-up visits on Day 18 and Day 28. Concomitant medications will be tracked throughout, i.e., from the time of screening, admission into the inpatient stay (Day 11), through discharge (Day 12) and at follow-up visits on Day 18 and Day 28. Directed physical exams will be performed at admission, Day 11, Day 12 (discharge) and follow-up visits on Day 18 and Day 28. ECGs will be performed at admission, on Days -1, Day 1 (at time of dosing and at 4 hours post dose), Day 4 and Day 11. Safety laboratory assessments will be conducted at admission, Day 1, Day 4 and Day 11.

ESRS will be assessed at screening, admission, while in patient on Day -1, Day 1, Day 3, Day 5, Day 7, Day 11 and at the End of Study (EOS) (Day 28).
CGI-S will be conducted at screening, admission, while in patient on Day -1, Day 1, Day 3, Day 5, Day 7, Day 11 and at follow-up visits on Day 18 and Day 28 (EOS).
C-SSRS will be assessed at screening, admission, while in patient on Day -1, Day 11 and at follow-up visits on Day 18 and Day 28.
Primary outcome [2] 321746 0
