What is the purpose of this trial?

This trial tests a new drug, tavapadon, to evaluate its effectiveness and safety for people with Parkinson's Disease. Researchers aim to determine if tavapadon can help manage symptoms in individuals who have had Parkinson's for less than three years and are in the early stages of the disease. Participants will receive either tavapadon or a placebo (a pill with no active drug) for 27 weeks. This trial may suit those recently diagnosed with Parkinson's and experiencing changes that might require medication. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to potentially groundbreaking treatment advancements.

Will I have to stop taking my current medications?

The trial requires participants to refrain from taking certain Parkinson's Disease medications that are not allowed by the protocol, including dopaminergic agents. However, if you are using MAO-B inhibitors, you can continue as long as the dosage remains stable throughout the trial.

Is there any evidence suggesting that tavapadon is likely to be safe for humans?

Research has shown that tavapadon is generally well-tolerated by people with Parkinson's Disease. Most side effects are mild to moderate, meaning they are not too serious and can often be managed. For example, one study found that tavapadon caused only mild side effects in patients with early-stage Parkinson’s. Another study confirmed its safety for long-term use, while also helping patients improve their movement.

Overall, these findings suggest that tavapadon is safe enough for further testing in trials. However, side effects can still occur, and each person's experience may differ. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for Parkinson's Disease?

Tavapadon is unique because it targets Parkinson's disease in a fresh way by acting as a selective dopamine D1/D5 receptor agonist. This is different from the usual treatments like levodopa, which generally increase dopamine levels broadly. Researchers are excited because this targeted approach may reduce the risk of common side effects, such as dyskinesia, and potentially offer improved motor symptom control. This could mean a better quality of life for people with Parkinson's disease.

What evidence suggests that tavapadon might be an effective treatment for Parkinson's Disease?

Research shows that Tavapadon, which participants in this trial may receive, effectively treats Parkinson's disease. Studies have found that Tavapadon increases the "ON" time—when patients experience better movement control without unwanted movements—by 1.1 hours compared to a placebo. The TEMPO-4 study found it safe for long-term use and effective in improving movement abilities. These findings suggest that Tavapadon can effectively help manage Parkinson's disease symptoms. ^{1 2 3 4 6}
