Abstract

IMPORTANCE: Muscle-related statin intolerance is reported by 5% to 20% of patients. OBJECTIVE: To identify patients with muscle symptoms confirmed by statin rechallenge and compare lipid-lowering efficacy for 2 nonstatin therapies, ezetimibe and evolocumab. DESIGN, SETTING, AND PARTICIPANTS: Two-stage randomized clinical trial including 511 adult patients with uncontrolled low-density lipoprotein cholesterol (LDL-C) levels and history of intolerance to 2 or more statins enrolled in 2013 and 2014 globally. Phase A used a 24-week crossover procedure with atorvastatin or placebo to identify patients having symptoms only with atorvastatin but not placebo. In phase B, after a 2-week washout, patients were randomized to ezetimibe or evolocumab for 24 weeks. INTERVENTIONS: Phase A: atorvastatin (20 mg) vs placebo. Phase B: randomization 2:1 to subcutaneous evolocumab (420 mg monthly) or oral ezetimibe (10 mg daily). MAIN OUTCOME AND MEASURES: Coprimary end points were the mean percent change in LDL-C level from baseline to the mean of weeks 22 and 24 levels and from baseline to week 24 levels. RESULTS: Of the 491 patients who entered phase A (mean age, 60.7 [SD, 10.2] years; 246 women [50.1%]; 170 with coronary heart disease [34.6%]; entry mean LDL-C level, 212.3 [SD, 67.9] mg/dL), muscle symptoms occurred in 209 of 491 (42.6%) while taking atorvastatin but not while taking placebo. Of these, 199 entered phase B, along with 19 who proceeded directly to phase B for elevated creatine kinase (N = 218, with 73 randomized to ezetimibe and 145 to evolocumab; entry mean LDL-C level, 219.9 [SD, 72] mg/dL). For the mean of weeks 22 and 24, LDL-C level with ezetimibe was 183.0 mg/dL; mean percent LDL-C change, -16.7% (95% CI, -20.5% to -12.9%), absolute change, -31.0 mg/dL and with evolocumab was 103.6 mg/dL; mean percent change, -54.5% (95% CI, -57.2% to -51.8%); absolute change, -106.8 mg/dL (P < .001). LDL-C level at week 24 with ezetimibe was 181.5 mg/dL; mean percent change, -16.7% (95% CI, -20.8% to -12.5%); absolute change, -31.2 mg/dL and with evolocumab was 104.1 mg/dL; mean percent change, -52.8% (95% CI, -55.8% to -49.8%); absolute change, -102.9 mg/dL (P < .001). For the mean of weeks 22 and 24, between-group difference in LDL-C was -37.8%; absolute difference, -75.8 mg/dL. For week 24, between-group difference in LDL-C was -36.1%; absolute difference, -71.7 mg/dL. Muscle symptoms were reported in 28.8% of ezetimibe-treated patients and 20.7% of evolocumab-treated patients (log-rank P = .17). Active study drug was stopped for muscle symptoms in 5 of 73 ezetimibe-treated patients (6.8%) and 1 of 145 evolocumab-treated patients (0.7%). CONCLUSIONS AND RELEVANCE: Among patients with statin intolerance related to muscle-related adverse effects, the use of evolocumab compared with ezetimibe resulted in a significantly greater reduction in LDL-C levels after 24 weeks. Further studies are needed to assess long-term efficacy and safety. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01984424.

  • The trials comparing statin-based therapy to placebo showed similar between-group incidence of muscle symptoms and statin-discontinuation rate.

    “The trials comparing statin-based therapy to placebo showed similar between-group incidence of muscle symptoms and statin-discontinuation rate. [20,21,25,26,43,47]”

    In Statin Rechallenge Outcomes, muscle symptoms were significantly more likely with atorvastatin than placebo in both treatment periods (HR 1.34 and 1.96). The same section reports intolerable symptoms with atorvastatin but not placebo in 42.6% of patients, versus 26.5% with placebo but not atorvastatin. The Discussion notes similar symptom rates only during the first 50 days, not across the full comparison. (LLM, conf=0.88)

    Checked by a reasoning model — may be wrong.

  • In the GAUSS 3 trial after 24 weeks, LDL cholesterol reductions were 54.5% with evolocumab compared with 16.7% with ezetimibe, with slightly higher rates of musculoskeletal adverse events (20.7% with evolocumab and 28.8% with ezetimibe).

    “Similar LDL cholesterol reductions were demonstrated in the GAUSS 3 trial after 24 weeks (54.5% with evolocumab compared with 16.7% with ezetimibe), with slightly higher rates of musculoskeletal adverse events (20.7% with evolocumab and 28.8% with ezetimibe).”

    Table 3 reports LDL-C reductions of 54.5% with evolocumab and 16.7% with ezetimibe for the mean of weeks 22 and 24. At week 24 alone, the reductions were 52.8% and 16.7%, respectively. The Safety and Tolerability Outcomes section confirms muscle-related adverse-event rates of 20.7% and 28.8%, with the higher rate in the ezetimibe group. (LLM, conf=0.90)

    Table 3 (Coprimary End Points) reports LDL-C reductions of 54.5% with evolocumab and 16.7% with ezetimibe for the mean of weeks 22 and 24. At week 24 specifically, the reductions were 52.8% and 16.7%, respectively, so the claim assigns the evolocumab figure to a more specific time point than the paper does. (LLM, conf=0.88)

  • Most trials used statins with low to moderate intensity.

    “Most trials used statins with low to moderate intensity [20,21,24–26,40,43,46,48,49]”

    From Safety outcomes of statin vs non-statin lipid-lowering interventions in patients with prior statin-associated muscle symptoms: A systematic review and meta-analysis (2025) · cites this paper as [20]

    The Abstract (page unavailable) says GAUSS-3 used atorvastatin 20 mg in its statin-rechallenge phase, consistent with moderate-intensity statin use in this trial. It does not establish that most of the trials cited used low- to moderate-intensity statins; its subsequent treatment phase compared two nonstatin drugs. (LLM, conf=0.78)

    Experimental — accuracy not yet measured
  • The outcomes of interest of our systematic review were not the main outcomes or the pre-specified outcomes of some studies.

    “The quality of non-randomized study was generally poor and the outcomes of interest of our systematic review were not the main outcomes or the pre-specified outcomes of some studies [20,46,47].”

    From Safety outcomes of statin vs non-statin lipid-lowering interventions in patients with prior statin-associated muscle symptoms: A systematic review and meta-analysis (2025) · cites this paper as [20]

    The paper’s “Primary and Secondary End Points” section identifies LDL-C changes as the coprimary outcomes and says cardiovascular events were adjudicated rather than listing them among the primary efficacy outcomes. This supports the concern if those events were outcomes of interest to the review, but the cited paper cannot establish what outcomes the citing authors’ review sought or whether they were prespecified in other studies.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
