Study Endpoints

Primary Endpoints

Number of Participants With Adverse Events (AEs) Post-conversion From Ropinirole IR to Ropinirole CR Over Period
Up to 5 weeks

AE is an unfavorable change in the health of a participant, including abnormal laboratory findings, that happens during a clinical study or within a certain time period after the study has ended. This change may or may not be caused by the intervention being studied. In each of the 6 cohorts, there were 2 conversions, one of which was IR to CR-RLS and the other one IR to IR. Two populations were defined: the first conversion population and the second conversion population. The first conversion population consisted of all participants receiving at least one dose of randomized drug during the pre-conversion 1 period and during the post-conversion 1 period. The second conversion population consisted of all participants receiving at least one dose of randomized drug during the pre-conversion 2 period and during the post-conversion 2 period.

Secondary Endpoints

Frequently asked questions about Ropinirole IR

What is Ropinirole IR used for?

Ropinirole IR is used for Restless Legs Syndrome (RLS). It is an immediate-release small molecule being developed by GSK plc for this neurological condition. The drug is currently in Phase 3 clinical development, meaning it is still investigational and has not yet been approved for use.

What does Ropinirole IR target?

Ropinirole IR is a small molecule that acts as a dopamine agonist, targeting dopamine receptors in the brain. By stimulating these receptors, it helps to alleviate the symptoms of Restless Legs Syndrome. This mechanism is central to its therapeutic effect in treating the condition.

Who makes Ropinirole IR?

Ropinirole IR is being developed by GSK plc, a global pharmaceutical company listed on the stock exchange under the ticker GSK. The company is conducting clinical trials to evaluate the drug's safety and efficacy for the treatment of Restless Legs Syndrome.

What phase is Ropinirole IR in?

Ropinirole IR is in Phase 3 clinical development. This is the final stage of testing before a potential regulatory submission. The drug is still investigational and has not been approved by regulatory authorities. One Phase 3 trial has been completed, involving 135 participants.

What clinical trials is Ropinirole IR in?

Ropinirole IR has one completed Phase 3 clinical trial registered under NCT00256854. The trial, titled 'Converting From Ropinirole Immediate Release (IR) To Ropinirole Controlled-Release for RLS', enrolled 135 participants in the United States. The study was controlled but not double-blind, and it included adults aged 18 years and older.

Is Ropinirole IR the same as ropinirole controlled-release?

Ropinirole IR is the immediate-release formulation of ropinirole, which is different from the controlled-release version. The clinical trial NCT00256854 specifically studied converting patients from the immediate-release to the controlled-release formulation for Restless Legs Syndrome, indicating they are distinct formulations of the same active ingredient.
