Efficacy, Safety and Cost-efficacy of a Pre-emptive Genotyping Strategy in Patients Receiving Statins

Instituto de Investigación Hospital Universitario La Paz216 enrolled

Overview

This is a Phase IV multicentre adaptive single-blinded randomized clinical trial if preemptively genotyping populations at risk of cardiovascular disease susceptible of receiving high or moderate doses of statin therapy is efficacious, cost-efficacious, and feasible within the Spanish National Health System when compared to the current standard of care. This trial is nested within the iPHARMGx master protocol

This is a nation-wide, multicentre, randomised, controlled, and adaptive phase IV clinical trial that aims to assess the efficacy and cost-efficacy of pre-emptive pharmacogenetic testing strategies, including those impacted by genetic variants associated with adverse drug reactions (ADRs) or limited efficacy. Populations at high-risk of developing clinically relevant outcomes will be enrolled in nested trials within this master protocol. The clinical trials will evaluate the efficacy and cost-efficacy of pre-emptive genotyping by defining a drug-gene-endpoint triad. Study subjects will be pre-emptively genotyped and, if found to have an actionable gene variant, randomly allocated to either a test group where guideline-based treatment modifications will be initiated or a control group that will be managed according to healthcare provider standard of care (SoC). Subsequently, subjects will be prospectively followed at prespecified timepoints. Detailed information on drug-gene-endpoint triads, allocation schemes, and follow-up visits will be provided in each of the subprotocols. A Data Monitoring Committee (DMC), composed of physician experts, will be appointed for each nested trial to review the data on an ongoing basis, ensuring the safety of participants and scientific validity of the study.

Primary Outcomes

Incidence of clinically relevant statin-associated musculoskeletal events

As defined by the a composite endpoint: Patients with a clinically relevant statin-associated musculoskeletal symptom defined as a combination of a SAMS-CI (Statin Associated Muscular Symptoms Clinical Index) score ≥7 points and a NPRS (Numerical Pain Rating Scale) score ≥3) in the 9-month follow-up period Serum creatin phosphokinase (CPK) \[UI/L\] greater than three times the upper limit of normality prespecified by each centre's laboratory, in relation to the statin.

Time frame: 9-months

Secondary Outcomes

Low density lipoprotein cholesterol (LDLc) serum concentration baseline reduction rate

Percentage of Baseline LDLc serum concentration reduction rate when compared to LDLc serum concentration values at 9 months.

Time frame: 9-months

Baseline change in statin therapy prescription

Percentage of patients that require either a statin dose modification/withdrawal or additional lipid-lowering therapy after 9 months in order to meet LDLc goals.

Time frame: 9-months

Cost of a statin preemptive pharmacogenetic prescription scheme

To quantify economic burden a cost-benefit analysis defined as the difference \[in monetary units, euros\] between the costs of the intervention \[pharmacogenetic analysis\] and all its surrounding procedures \[personnel, geneticist report, clinical pharmacologist report\] combined with the costs derived from the events \[blood sample analysis, hospital admission, follow-up visits, lipid-lowering therapy modification\] in the intervention arm when compared to the costs derived from the events in the control arm alone Monetary units requiered to prevent a event will be calculated through an incremental cost effectiveness ratio (ICER) between intervention and control arm .

Time frame: Though study completion, on average 18 months
