The MASTER Study (MAmmary Cancer STatin ER Positive Study)

NCT04601116

Description:

Given the compelling evidence supporting a protective effect of statins on breast cancer recurrence, calls for prospective clinical trials have been expressed. In this trial - the MASTER trial - we hypothesize that the addition of statin treatment to the current breast cancer treatment will improve the prognosis of women with early breast cancer. This trial is designed as follows: a randomized, multicenter, double-blind, placebo-controlled comparison of standard (neo)adjuvant therapy plus placebo versus standard (neo)adjuvant therapy plus atorvastatin in patients with early breast cancer.

Purpose

Given the compelling evidence supporting a protective effect of statins on breast cancer recurrence, calls for prospective clinical trials have been expressed. In this trial - the MASTER trial - we hypothesize that the addition of statin treatment to the current breast cancer treatment will improve the prognosis of women with early breast cancer. This trial is designed as follows: a randomized, multicenter, double-blind, placebo-controlled comparison of standard (neo)adjuvant therapy plus placebo versus standard (neo)adjuvant therapy plus atorvastatin in patients with early breast cancer.

Detailed Description

      Cholesterol-lowering drugs such as statins are currently used to lower cholesterol levels and
      prevent cardiovascular events. Statins have, however, received substantial scientific
      attention as cancer-inhibiting drugs. Previous findings were recently supported in a
      large-scaled study again demonstrating the beneficial effects of statins on breast cancer
      outcome this time nested within a large, international, randomized clinical trial of modern
      adjuvant cancer therapy. Given the compelling evidence supporting a protective effect of
      statins on breast cancer recurrence, calls for prospective clinical trials have been
      expressed. In this trial - the MASTER trial - we hypothesize that the addition of statin
      treatment to the current breast cancer treatment will improve the prognosis of women with
      early breast cancer. Thus, the primary objective of the MASTER trial is to determine the
      clinical efficacy of the statin - atorvastatin - as measured by invasive disease-free
      survival among patients with primary breast cancer.

      The trial is nationwide throughout Denmark and a total of 3,360 women are to be included in
      the trial. Women eligible for the trial have been diagnosed with an estrogen receptor
      positive breast cancer and are candidates for systemic cancer therapy, either prior to or
      following breast surgery. Upon eligibility and signed informed consent, trial participants
      will be randomized in a 1:1 manner to either standard treatment and atorvastatin 80 mg/day or
      standard treatment and placebo. The randomization is blinded. The treatment with atorvastatin
      or placebo will continue for two years unless side effects are experienced and further
      treatment with atorvastatin or the placebo is deemed inadequate. The standard treatment will
      of course continue as planned. The trial participants will follow the standard clinical
      routines in terms of follow-up and in addition they are asked to fill in questionnaires, i.e.
      regarding potential side effects or new events or diagnoses, up to ten years following
      inclusion. Potential breast cancer recurrences are hereby identified and a follow-up of at
      least 61/2 years will be required for the trial the demonstrate the estimated clinical
      difference between the randomized groups of patients.

Eligibility Criteria

        Patients must meet ALL of the following criteria to be eligible for randomization:

        Inclusion Criteria:

          1. Women with estrogen receptor positive breast cancer who are candidates for
             (neo)adjuvant systemic therapy OR have received ≤3 years of adjuvant endocrine
             therapy.

          2. Age > 18 years.

          3. Performance status of ECOG ≤ 2.

          4. Prior to patient registration, written informed consent must be given according to
             ICH/GCP, and national/local regulations.

        Patients meeting ANY one of the following criteria are not eligible:

        Exclusion Criteria:

          1. History of any prior (ipsi- and/or contralateral) invasive breast carcinoma.

          2. Ongoing (prevalent) cholesterol-lowering therapy (statins, fibrates, ezetimibe, PCSK9
             inhibitors). If so, the patient can be enrolled in the observational arm.

          3. Evidence of hepatic dysfunction (alanine aminotransferase level more than three times
             the upper limit of the normal range) or renal dysfunction (creatinine level more than
             three times the upper limit of the normal range).

          4. Predisposing factors for rhabdomyolysis, including hypothyroidism, reduced renal
             function, any muscle - or liver disease, or excessive alcohol consumption AND creatine
             kinase (CK) measured to less than five times the upper limit (CK only measured in case
             of predisposing factors).

          5. No current medication with potent CYP3A4-inhibitors (e.g. ketokonazole, erythromycin)
             or gemfibrozile, cyclosporin or danazol.

          6. Pregnancy or breast-feeding.

          7. Psychological, familial, sociological or geographical condition potentially hampering
             compliance with the study protocol and follow-up schedule; these conditions will be
             discussed with the patient before registration in the trial.

          8. History of allergic reactions attributed to compounds of similar chemical or
             biological composition to atorvastatin.
