About this study

Official title: 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.

Read the 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Trans-ResveratrolDrug

    Also called JOTROLTM, JNS115

    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.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Trans-Resveratrol in people with Parkinson's Disease, run by Georgetown University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 18 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Luke Lovelace, BS, MBA (757-802-5001, ll928@georgetown.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability] (time frame: 12 weeks). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Sep 2026.
