A Study to Investigate the Efficacy and Safety of NT 201 (Botulinum Toxin) Compared With Placebo for the Treatment of Adult Participants With Essential Tremor in the Arm
NCT04766723 · View on ClinicalTrials.gov ↗
Study Summary
The purpose of this study is to determine whether a single treatment with administration of NT 201 (botulinum toxin) is superior to placebo (no medicine) for one-sided treatment of essential tremor in the arm (Unilateral Period). Participants will be assigned to the treatment groups by chance and neither the participants nor the research staff who interact with them will know the allocation. The following treatment cycle will investigate the safety and tolerability of two-sided treatment with NT 201 (botulinum toxin) (Open Label Bliaterial Period). All participants will receive NT 201 treatment.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04766723
The ClinicalTrials.gov registry entry for NCT04766723 describes a study currently listed as completed. It is categorized as Phase 2, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 78 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Merz Pharmaceuticals, which has 5 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Essential Tremor of the Upper Limb appearing as the primary indexed condition, and to 2 interventions — of which Placebo is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04766723 reports 14 study locations spanning 10 distinct geographic areas — top geographies include Other, Washington, Florida. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
