Anti-HMGCR antibodies as a biomarker for immune-mediated necrotizing myopathies: A history of statins and experience from a large international multi-center
The study included patients who were part of the longitudinal cohort of the Johns Hopkins Myositis Center, Baltimore. Among the 122 patients with immune-mediated necrotizing myopathy associated with anti-HMGCR autoantibodies in the cohort, eight patients with severe cardiovascular disease and/or diabetes were using PCSK9 inhibitors for hyperlipidemia.
This is a phase 2, double-blinded, randomized, placebo-controlled, multi-center trial of Gamunex-C IVIG as mono-therapy for HMGCR necrotizing myopathy. Up to 10 treatment-naïve patients will be enrolled and randomized to receive either Gamunex-C IVIG dosed at 2g/kg or placebo at week 0 and week 4.

Anti-HMGCR Myopathy Payam Mohassela and Andrew L. Mammenb,∗ aNational Institutes of Health, NINDS, Bethesda, MD, USA bNational Institutes of Health, NIAMS, Bethesda, MD, USA Abstract. Anti-HMGCR myopathy was first recognized and characterized in patients with a history of statin exposure and immune-mediated necrotizing myopathy. Statin-associated IMNM is a recently described entity based on the development of autoantibodies against the enzyme HMGCR, and leads to a necrotizing myopathy requiring immunosuppressive therapy. 7 In this review, we recapitulate the definition, clinical picture, pathophysiology and therapeutic options of the anti-HMGCR myopathy. Statin Myopathy

Like other forms of myositis, patients with necrotizing myopathy may experience the following symptoms: Weakness in the muscles closest to the center of the body, such as the forearms, thighs, hips, shoulders, neck, and back Difficulty climbing stairs and standing up from a chair Difficulty lifting More recently, a subset of cases of immune-mediated necrotising myopathy has been found to have antibodies against HMGCR. It is often an aggressive and debilitating myopathy and has a complex pathogenesis characterised by fibre necrosis, usually with minimal associated inflammation. Not all such patients are taking statins.

Immunol. Res. 65 , 276–281 (2017). Objective: We examined a cohort of Australian patients with statin exposure who developed a necrotizing autoimmune myopathy (NAM) associated with a novel autoantibody against 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) and describe the clinical and therapeutic challenges of managing these patients and an optimal therapeutic strategy. Methods: Clinical, laboratory, EMG, and Objective. A pathogenic role of anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (anti-HMGCR) antibodies has been proposed.
