About this study

Official title: MUscle Side-Effects of Atorvastatin in Coronary Patients (MUSE) -a Randomized Controlled Trial

The study aims to estimate the effect of atorvastatin on muscular symptom intensity in coronary patients with subjective statin-associated muscle symptoms (SAMS) and to determine the association with blood levels of atorvastatin and its metabolites, to obtain an objective marker for true SAMS. A randomized study will include 80 coronary patients with SAMS during ongoing atorvastatin therapy or previous muscle symptoms that led to discontinuation of atorvastatin. Patients will be randomized to 7-weeks treatment with atorvastatin 40 mg/day in the first period and matched placebo in the second 7-weeks period, or placebo in the first period and atorvastatin in the second period. A control group (n=40) without muscle symptoms will have 7 weeks open treatment with atorvastatin 40 mg/day. Blood samples will be collected at baseline and after each treatment period, and muscular symptom intensities will be rated by the patients weekly. The primary outcome is the difference in aggregated mean Visual Analogue Scale (VAS) scores between the last three weeks of atorvastatin treatment and of placebo treatment. The main purpose is to develop an objective marker for true SAMS, by comparing SAMS associated with blinded atorvastatin treatment with blood concentrations of atorvastatin and its metabolites. Diagnostic and discrimination performance will be determined. The study provides new clinical knowledge on SAMS in coronary patients and may contribute to more personalized statin treatment and monitoring, fewer side-effects and consequently improved adherence and lipid management in future practice.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Individual mean difference in muscular symptom intensity measured with a 0 (no symptoms) to 10 (worst imaginable symptoms) Visual Analogue Scale (VAS) score between treatment periods with statin and placebo

    Individual mean difference in muscular symptom (i.e. pain, aching, tenderness, stiffness, cramp and/or weakness) intensity between treatment periods with statin and placebo, reported by the patients over the last three weeks (i.e. week 4-7) measured with a 0 (no symptoms) to 10 (worst imaginable symptoms) Visual Analogue Scale (VAS) score with aggregated data from each subscale

    Measured: 16 weeks following randomization

Secondary outcomes (9)
  1. The proportion of patients who report muscle symptoms on atorvastatin treatment and not on placebo (dichotomous Statin Associated Muscle Symptom classification)

    Measured: 16 weeks following randomization

  2. The correlation between individual muscular symptom intensity between treatment periods with statin and placebo over the last three weeks measured with 0 to 10 VAS score aggregated from each subscale, and levels of atorvastatin and metabolites

    Measured: 16 weeks following randomization

  3. Sensitivity, specificity, and area under the curve of blood concentrations of parent drug and the active metabolites of atorvastatin for the classification of true Statin Associated Muscle Symptoms (SAMS)

    Measured: 16 weeks following randomization

  4. Individual mean difference in likelihood of statin discontinuation between treatment periods with statin and placebo over the last three weeks (i.e. week 4-7) measured with 0 to 10 VAS score with aggregated data from each subscale.

    Measured: 16 weeks following randomization

  5. Statin adherence measured weekly with self-reported questionnaire methods during the study periods

    Statin adherence measured with self-reported questionnaires (numeric scale: <4/7, 5/7, 6/7 or 7/7) weekly during the treatment periods. Low statin adherence will be defined by taking statins less than 42 of 49 days during the 7 weeks treatment period

    Measured: 16 weeks following randomization

  6. Statin adherence measured with pill counts of returned packages

    Statin adherence measured with pill counts of returned packages. Low statin adherence will be defined by a total of >=8 returned pills during the treatment periods

    Measured: 16 weeks following randomization

  7. Statin adherence measured with direct liquid chromatography-tandem mass spectrometry methods

    Statin adherence measured with direct liquid chromatography-tandem mass spectrometry methods. Low statin adherence defined by dose-normalized statin and metabolites concentrations < 0.10 (nmol/L)/mg

    Measured: 16 weeks following randomization

  8. Levels of atorvastatin and its metabolites in blood plasma and white blood cells at study end

    Measured: 16 weeks following randomization

  9. Number of patients with new-onset coronary heart disease symptoms, intolerable muscle symptoms leading to discontinuation from the treatment arm, and elevated levels of creatine kinase (CK) and/or Alanine Aminotransferase (ALT) in blood

    Safety endpoints: i.New-onset coronary heart disease symptoms. ii Intolerable muscle symptoms leading to discontinuation from the treatment arm.iii elevated levels of creatine kinase (CK) and/or Alanine Aminotransferase (ALT) in blood

    Measured: 16 weeks following randomization

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Atorvastatin 40mg in people with Statin Adverse Reaction, run by Vestre Viken Hospital Trust at 2 sites in Norway.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Norway. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Individual mean difference in muscular symptom intensity measured with a 0 (no symptoms) to 10 (worst imaginable symptoms) Visual Analogue Scale (VAS) score between treatment periods with statin and placebo (time frame: 16 weeks following randomization). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03874156, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Jan 2020.
