About This Trial

A study to determine if BHV-8000 is efficacious, safe and tolerable in adults diagnosed with early Parkinson's disease.

What Stage of Research Is This?

Phase 2 trials evaluate whether a treatment actually works against Parkinson Disease and continue monitoring side effects. Phase 2 enrolls larger groups (typically 100–300 patients) and produces the first real efficacy signal. A successful Phase 2 readout is what unlocks the much larger Phase 3 confirmatory trials needed for FDA approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

A target enrollment of 550 participants makes this a sizable late-stage trial. Studies in this range typically have enough power to detect clinically meaningful differences from a comparator and to characterize less-common side effects.

Who May Be Eligible (Plain English)

Key Who May Qualify: - Male or female participants 40 to 85 years of age, inclusive, at the time of willing to sign a consent form. - Meet the diagnostic criteria for "Probable PD" as assessed on the Movement Disorder Society (MDS) Clinical Diagnostic Criteria for PD as assessed by the Investigator. - Have a clinician-documented diagnosis of idiopathic PD with an onset within 2 years of the Screening Visit Key Who Should NOT Join This Trial: - Medical history indicating a Parkinsonian syndrome other than idiopathic PD, including, but not limited to, progressive supranuclear gaze palsy, multiple system atrophy, drug-induced Parkinsonism, essential tremor, or primary dystonia. - Diagnosis of clinically significant central nervous system (CNS) disease other than PD. - Participants who are current smokers (defined as smoking \[in any form, e.g., tobacco smoke, electronic cigarettes, etc.\] ) - Treatment with PD medication(s) - Any other condition(s) that may compromise participant safety, interfere with study conduct, or jeopardize the potential proper interpretation of study results, in the opinion of the investigator. Always talk to your doctor about whether this trial is right for you.

How to Talk to Your Doctor About This Trial

Bring the printable summary of this trial — including the NCT ID (NCT06976268), the sponsor (Biohaven Therapeutics Ltd.), and the key eligibility criteria — to your next appointment. Your doctor can review the inclusion and exclusion criteria against your medical history, lab values, and current treatments to assess whether you are likely to qualify. They can also help you weigh whether trial participation makes sense alongside your existing care plan.

Useful questions to walk through together: What does the trial protocol require beyond standard care? How long is the active treatment phase, and how long is follow-up? Are there study visits at sites I can reach? Who pays for the trial-specific procedures, and who pays for standard-of-care portions? See our 25 questions to ask about clinical trials guide for a more complete checklist.

Frequently Asked Questions

What is the NCT06976268 clinical trial studying?

A study to determine if BHV-8000 is efficacious, safe and tolerable in adults diagnosed with early Parkinson's disease. The full protocol is registered on ClinicalTrials.gov and includes the primary outcome measures, eligibility criteria, and study endpoints.

Who can participate in NCT06976268?

Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.

How do I contact the trial site for NCT06976268?

Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.

Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
