Trial Outcomes & Findings for Study On Utilization Of Cabergoline For Compliance With Risk Minimization Activities (SUCRE) (NCT NCT01270711)

NCT ID: NCT01270711

Last Updated: 2014-05-02

Results Overview

Cabergoline prescriptions were stratified by indications per year. Indications were coded using Anatomical Therapeutic Code (ATC) which included G02CB03 for prolactin reduction indication and N04BC06 for neurological indication.

Participant Flow

Part 1 recruited participants from North, Middle and South Europe and Part 2 from specialized clinical centers in Italy.

Part 1 assessed adherence (compliance) with prescribing guidelines (PG) by using automated health care data which had information on strength, indication, referrals for echocardiography, recognized reputation in area of drug utilization, safety research. Part 2 assessed effectiveness of PG for cabergoline in participants with Parkinson's disease.

Cabergoline in Pre-SPC Change Period [Part 2]
Participants who started cabergoline treatment for Parkinson's disease prior to the date of the recommended Summary of Product Characteristics (SPC) change, 26 June 2008 (Week 130) and stopped treatment before the recommended change to the SPC.
Cabergoline in Post- SPC Change Period [Part 2]
Participants who started cabergoline treatment for Parkinson's disease after the date of the recommended SPC change, 26 June 2008 (Week 130).
Cabergoline in Cross-SPC Change Period [Part 2]
Participants who started cabergoline treatment for Parkinson's disease prior to date of the recommended SPC change, 26 June 2008 (Week 130) and continued treatment after the recommended change to the SPC.

Timeframe: Year 1 (Year 2006)

Population: Study population: participants registered in one of databases and were treated with cabergoline during study period. Data not reported for IPCI and PHARMO databases because no information was retrieved for second-line prescriptions of cabergoline for Parkinson's disease. 'N' (number of participants analyzed)=participants evaluable for this measure.

Changes to the Summary of Product Characteristics (SPC) included that the cabergoline should be used for Parkinson's disease only in participants who had already taken or cannot take other treatments, which was as second line therapy. Second-line use restriction did not apply to the hyperprolactinemia indication, for which cabergoline was considered a first-time therapy. Percentage of second-line prescriptions of a total number of prescriptions for cabergoline during a respective year for the neurological indication was reported.

Total Number of Echocardiography Examinations in Cabergoline Users
11 echocardiography examinations
3 echocardiography examinations
68 echocardiography examinations

PRIMARY outcome

Timeframe: Baseline (Week 1) up to Week 339

Population: Study population:all participants recruited from specialized clinical centers in Italy and treated with cabergoline for Parkinson's disease during study period.

Incidence of valvular fibrosis was calculated as number of participants with documented valvulopathy during cabergoline treatment and absence of any valve damage at baseline divided by number of participants without any valve damage at baseline and at least 1 additional echocardiography examination during follow-up while on cabergoline treatment. Percentage of participants with valvular fibrosis are reported.
