Description of intervention(s) / exposure
Intervention: Extended release (ER) Dapagliflozin (LYN-045)
Administration: oral (capsules)

A total of 10 subjects are planned to be enrolled, 2 in the sentinel group and 8 in the main group. All subjects will receive 3 doses of Immediate release (IR) dapagliflozin 10 mg in the inpatient unit, Dose 1 on Day -3, Dose 2 on Day -2, and Dose 3 on Day -1. Following that, all subjects will receive 2 doses of LYN-045 70 mg. Dose 1 will be administered in the inpatient unit on Day 1, dose 2 of LYN-045 will be administered on Day 8. The mouth cavity is inspected after administration of the capsule.

A review of safety information will be performed after the 2 sentinel subjects complete 2 days of observation after dosing with the initial dose of LYN-045. The safety data will be reviewed by the Investigator to determine whether enrollment of subjects in the main group may proceed.

Summary
Brief summary
Lyndra Therapeutics is currently developing extended release (ER) capsules for weekly administration across therapeutic areas with certain medications for which consistent pharmacokinetics (PK) or enhanced adherence may translate to improved efficacy, and possibly better safety. LYN-045 (Lyndra code for dapagliflozin) ER capsules are intended to provide comparable dapagliflozin exposure to daily treatment affording better accessibility and tolerability for the treatment of type 2 diabetes mellitus (T2DM).

This Phase 1 study is intended for execution in healthy individuals due to its exploratory nature. Data from this study will be a key indicator of feasibility of the product concept and will inform formulation optimization and dose selection for further development.
This study will be conducted in up to 10 healthy volunteers (including 2 sentinels) who meet all of the inclusion criteria and none of the exclusion criteria.

This is a single-center, open-label study of dapagliflozin 70 mg ER capsules (LYN-045) to evaluate its safety, tolerability, and PK administered as 2 weekly doses in healthy male and female volunteers.
All subjects will receive 3 doses of IR dapagliflozin 10 mg in the inpatient unit, Dose 1 on Day -3, Dose 2 on Day -2, and Dose 3 on Day -1. Following that, all subjects will receive 2 doses of LYN-045 70 mg; on Day 1 and Day 8. After completion of Day 10 assessments, subjects will be discharged from the inpatient unit. Thereafter, subjects will attend study center visits on an outpatient basis on Days 14 and 15. All subjects will attend an End-of-Study (EOS) visit on Day 21 for final study assessments.
