RESvEraTrol in Parkinson's Disease (RESET) (RESET)

Multicenter, Randomized, Double Blind, Placebo-Controlled Phase 2a Study, to Evaluate Safety, Tolerability and Pharmacokinetics of Resveratrol (JOTROLTM) in Parkinson's Disease

This is an exploratory phase 2a study to investigate two doses of resveratrol (JotrolTM) vs placebo in individuals diagnosed with Parkinson's Disease (PD). Participants (n=30) will be randomized 1:1:1 into 3 groups and will receive oral JotrolTM vs placebo. Study drug will be titrated to reach a final maximal dose per group and will be administered orally once daily (QD) for 3 months. The study will primarily evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics (PK/PD) of JotrolTM.

Study Overview

• Status: Not yet recruiting
• Conditions: Parkinson's Disease
• Intervention / Treatment: Drug: Trans-Resveratrol

Detailed Description

Core Study. JotrolTM in subjects with PD is a 3-month treatment (Core Study). A total of 30 subjects will be randomized 1:1:1 across JotrolTM, 200mg or 400mg versus placebo.

Biomarker Sub-study (Optional). There will be an additional sub-study, including cerebrospinal fluid (CSF) biomarkers assessments. Participation in this sub study is optional and will require specific consent that will not affect enrollment or treatment in the Core Study.

Number of Centers: Approximately 3 centers US-Wide Duration of Treatment: Participants will take the study drug (JotrolTM or matching placebo) orally, QD, for 3 months. Participants will be in the study for a total period of 4-5 months.

Duration of Study: Enrollment will be (competitive) open for 1 year and total study duration is 2 years.

Screening period: Consent and enrollment will take 4 weeks to determine eligibility and stabilize all participants on the standard of care (SOC).

Eligible patients will be randomized into Arm A (Placebo), B (200mg JotrolTM) and C (400mg JotrolTM).

Titration: Participants in Arm A will resume taking 4 placebo capsules from Week 1 through Participants in Arm B will receive a single daily dose of 100mg JotrolTM in Week 1, and this dose will be escalated to 200mg at Week 2. If no Treatment Emergent Adverse Event (TEAE) is observed, participants will continue treatment with 200mg until Week 12.

Participants in Arm C will receive a single daily dose of 100mg JotrolTM in Week 1, and this dose will increase to 200mg JotrolTM at Week 2, and 300mg at Week 3 and 400mg at Week 4. If no TEAEs are observed, participants will continue 400mg JotrolTM through Week 12.

If any TEAE is observed during the titration period, participants will receive the prior (reduced) dose and continue the study until Week 12. If the TEAE recurs in the same patient with a lower dose, the participant will be withdrawn from the study.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Placebo Comparator: Placebo; Participants will resume taking 4 placebo capsules once a day from Week 1 through 12	Drug: Trans-Resveratrol; Resveratrol (RSV) - or Trans-resveratrol- is polyphenolic compound in many plants, including grape, peanut, and berries. Biologically, RSV is a Sirtuin (SIRT) 1 activator that stimulates mitochondrial biogenesis; and regulates mitochondrial dynamics via autophagy (referred to as mitophagy). RSV plays a role in parkin-related mitophagy, which is necessary for mitochondrial dynamics but it is deficient in neurodegenerative diseases, including PD. RSV inhibits the activation of the NLRP3 (nucleotide-binding domain, leucine-rich repeat, and pyrin domain-containing protein 3) inflammasome, thereby lowering inflammation. The parallel roles of RSV to inhibit the NLRP3 inflammasome, increase autophagy and maintain mitochondrial integrity indicate that RSV is a therapeutic candidate that has strong neuroprotective effects via autophagy and inhibition of the NLRP3 inflammasome.; Other Names: JOTROLTM; JNS115
Experimental: 200mg JotrolTM; In the first month, study drug will be titrated in multiple ascending doses. Participants will receive a single daily dose of 100mg JotrolTM in Week 1, and this dose will be escalated to 200mg at Week 2. If no Treatment Emergent Adverse Event (TEAE) is observed, participants will continue treatment with 200mg until week-12.
