Could KP405 offer a new way to tackle Parkinson's?
NCT ID NCT06189170
First seen Aug 05, 2026 · Last updated Aug 06, 2026 · Updated 1 time
Summary
This early-stage trial is evaluating the safety and tolerability of an experimental drug called KP405, which is being developed as a potential treatment for Parkinson's disease. The study will first give single and then multiple doses to healthy volunteers, and later include people with Parkinson's, to see how the drug is processed by the body and whether it causes any side effects. The goal is to gather essential safety data before larger studies can explore whether KP405 can actually help manage the disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- KP405
- What this could lead to
- If KP405 proves safe and well-tolerated, it could pave the way for a new treatment option to help manage Parkinson's disease symptoms.
- What could go wrong
- This is an early-phase trial focused on safety, not effectiveness. The drug may not work as hoped, and side effects are possible.

Inclusion Criteria: * Healthy as determined by a responsible physician, based on medical evaluation including medical history, physical examination, concomitant medication, vital signs, 12-lead ECG, cardiac Holter monitoring and clinical laboratory evaluations. * Clinical diagnosis of Parkinson's disease meeting United Kingdom Brain Bank criteria. Exclusion Criteria: * Clinically relevant history of abnormal physical or mental health interfering with the study as determined by medical history and physical examinations obtained during Screening as judged by the Investigator (including \[but not limited to\], neurological, psychiatric, endocrine, cardiovascular, respiratory, gastrointestinal, hepatic, or renal disorder), excluding Parkinson's disease. * Clinically significant, as judged by the Investigator, neurologic disorder (other than Parkinson's disease) including history of stroke or transient ischaemic attack within 12 months of Screening, cognitive impairment, seizure within 5 years of Screening or head trauma with loss of consciousness within 6 months of Screening.
