Subjects with minor forms of ectopy (eg, premature atrial contractions) are not necessarily excluded and may be discussed with the Medical Monitor for inclusion; * Prolonged QT interval corrected by Fridericia's formula (\>450 msec); * Seated systolic blood pressure (BP) \>140 mmHg and/or diastolic BP \>90 mmHg or systolic BP \<90 mmHg and/or diastolic BP \<50 mmHg; * Postural tachycardia (ie, \>30 bpm upon standing) or orthostatic hypotension (ie, a fall in systolic BP ≥20 mmHg or diastolic BP ≥10 mmHg upon standing); * Serum potassium \>upper limit of normal (ULN) of the reference range and serum sodium \1.2 × ULN; * Positive for human immunodeficiency virus antibody, hepatitis C virus antibody, hepatitis B surface antigen, or severe acute respiratory syndrome coronavirus 2 RNA; * Evidence or history of any clinically significant immunologic, hematologic, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, musculoskeletal, hepatic, psychiatric, neurologic, or allergic (including clinically significant or multiple drug allergies) disease; surgical conditions; cancer (with the exception of basal or squamous cell carcinoma of the skin and cancer that has resolved or has been in remission for \>5 years prior to Screening); or any condition that, in the Investigator's opinion, may confound study procedures or results, impact subject safety, or interfere with the absorption, distribution, metabolism, or excretion of the study drug (appendectomy allowed, cholecystectomy prohibited); * Typical consumption of ≥14 alcoholic drinks weekly; Note: 1 drink of alcohol is equivalent to ½ pint of beer (285 mL), 1 glass of spirits (25 mL), or 1 glass of wine (125 mL). * Surgical procedures within 4 weeks prior to Check-In (other than minor cosmetic surgery or minor dental procedures) or planned elective surgery during the treatment period; ``` ## Arms - **Treatment A: Immediate-release metformin** (ACTIVE_COMPARATOR) — Treatment A: single 1000 mg dose of immediate-release metformin Subjects will be randomly assigned to 1 of 2 sequences: AB or BA. * Treatment A: a single 1000 mg dose of immediate-release metformin; and * Treatment B: a single 1000 mg dose of immediate-release metformin coadministered with a 10 mg dose of CIN-107. All study medication will be administered at 8:00 AM (±2 hours). There will be a minimum 10-day washout between administration of study drug in each treatment period. - **Treatment B: Immediate-release metformin coadministered with a CIN-107** (EXPERIMENTAL) — Treatment B: a single 1000 mg dose of immediate-release metformin coadministered with a 10 mg dose of CIN-107 Subjects will be randomly assigned to 1 of 2 sequences: AB or BA. * Treatment A: a single 1000 mg dose of immediate-release metformin; and * Treatment B: a single 1000 mg dose of immediate-release metformin coadministered with a 10 mg dose of CIN-107. All study medication will be administered at 8:00 AM (±2 hours). For Treatment B, the dose of CIN-107 will be administered 2 hours prior to the dose of metformin. There will be a minimum 10-day washout between administration of study drug in each treatment period. ## Interventions - **Metformin** (DRUG) — 1000 mg dose of immediate-release metformin - **CIN-107** (DRUG) — 10 mg dose of CIN-107 ## Primary Outcomes - **Maximum plasma concentration (Cmax)** _(time frame: Up to day 3)_ — This plasma PK parameter will be determined for CIN-107, its primary metabolite (CIN-107-M), and any other measured metabolites. - **Time to Cmax (Tmax)** _(time frame: Up to day 3)_ — This plasma PK parameter will be determined for CIN-107, its primary metabolite (CIN-107-M), and any other measured metabolites. - **Area under the concentration-time curve (AUC) from time 0 to 72 hours** _(time frame: Up to day 3)_ — This plasma PK parameter will be determined for CIN-107, its primary metabolite (CIN-107-M), and any other measured metabolites. - **Maximum plasma concentration (Cmax) of metformin** _(time frame: Up to day 3)_ — This plasma PK parameter will be determined for metformin. - **Time to Cmax (Tmax) of metformin** _(time frame: Up to day 3)_ — This plasma PK parameter will be determined for metformin. - **AUC from time 0 to the time of last quantifiable plasma concentration of metformin** _(time frame: Up to day 3)_ — This plasma PK parameter will be determined for metformin. - **AUC from time 0 to infinity of metformin** _(time frame: Up to day 3)_ — This plasma PK parameter will be determined for metformin. - **Percent of AUC extrapolated of metformin** _(time frame: Up to day 3)_ — This plasma PK parameter will be determined for metformin. - **Terminal phase elimination half-life of metformin** _(time frame: Up to day 3)_ — This plasma PK parameter will be determined for metformin. - **Cumulative amount of metformin excreted in the urine (Ae) of metformin** _(time frame: Up to day 3)_ — This urine PK parameter will be determined for metformin. - **Renal clearance (calculated as Ae/AUC) of metformin** _(time frame: Up to day 3)_ — This urine PK parameter will be determined for metformin. - **Fraction of the dose excreted renally of metformin** _(time frame: Up to day 3)_ — This urine PK parameter will be determined for metformin. ## Locations (1) - Medpace Clinical Pharmacology Unit, Cincinnati, Ohio, United States ## Recent Field Changes (last 30 days) - `status.overallStatus` — added _(2026-05-12)_ - `status.primaryCompletionDate` — added _(2026-05-12)_ - `status.completionDate` — added _(2026-05-12)_ - `status.lastUpdatePostDate` — added _(2026-05-12)_ - `design.phases` — added _(2026-05-12)_ - `design.enrollmentCount` — added _(2026-05-12)_ - `eligibility.criteria` — added _(2026-05-12)_ - `eligibility.minAge` — added _(2026-05-12)_ - `eligibility.maxAge` — added _(2026-05-12)_ - `eligibility.sex` — added _(2026-05-12)_ - `outcomes.primary` — added _(2026-05-12)_ - `armsInterventions.arms` — added _(2026-05-12)_ - `armsInterventions.interventions` — added _(2026-05-12)_ - `sponsor.lead` — added _(2026-05-12)_ - `results.hasResults` — added _(2026-05-12)_ - `locations.medpace clinical pharmacology unit|cincinnati|ohio|united states` — added _(2026-05-12)_ --- *Canonical: https://parkinsonspathways.com/agent/trials/NCT05526690.md* *Source data (authoritative): https://clinicaltrials.gov/study/NCT05526690* *This page is a raw mirror with no AI summary, no editorial enrichment, and no Parkinson's-specific filtering.*
