The information aims to inform both healthcare providers and patients about the benefits and risks associated with these therapies.

Market Sentiment Analysis

CONCERNS & RISKS

  • NEXLIZET is associated with an increased risk of tendon rupture.
  • Serious hypersensitivity reactions such as anaphylaxis have been reported.
  • Use of NEXLIZET may lead to elevated uric acid levels, risking gout.
  • Adverse reactions like muscle spasms, back pain, and elevated liver enzymes were common in clinical trials.

Full Press Release Details

Discontinue NEXLIZET at the first sign of tendon rupture. Consider alternative therapy in patients who have a history of tendon disorders or tendon rupture. - The most common adverse reactions in the primary hyperlipidemia trials of bempedoic acid (a component of NEXLIZET) in 2% of patients and greater than placebo were upper respiratory tract infection, muscle spasms, hyperuricemia, back pain, abdominal pain or discomfort, bronchitis, pain in extremity, anemia, and elevated liver enzymes. - Adverse reactions reported in 2% of patients treated with ezetimibe (a component of NEXLIZET) and at an incidence greater than placebo in clinical trials were upper respiratory tract infection, diarrhea, arthralgia, sinusitis, pain in extremity, fatigue, and influenza. - In the primary hyperlipidemia trials of NEXLIZET, the most commonly reported adverse reactions (incidence 3% and greater than placebo) observed with NEXLIZET, but not observed in clinical trials of bempedoic acid or ezetimibe, were urinary tract infection, nasopharyngitis, and constipation. - The most common adverse reactions in the cardiovascular outcomes trial of bempedoic acid (a component of NEXLIZET) at an incidence of 2% and 0.5% greater than placebo were hyperuricemia, renal impairment, anemia, elevated liver enzymes, muscle spasms, gout, and cholelithiasis. - Discontinue NEXLIZET when pregnancy is recognized unless the benefits of therapy outweigh the potential risks to the fetus.
Assess uric acid levels periodically as clinically indicated. Monitor for signs and symptoms of hyperuricemia, and initiate treatment with urate-lowering drugs as appropriate. - Tendon Rupture: Bempedoic acid, a component of NEXLIZET, is associated with an increased risk of tendon rupture or injury. Tendon rupture may occur more frequently in patients over 60 years of age, in those taking corticosteroid or fluoroquinolone drugs, in patients with renal failure, and in patients with previous tendon disorders.
Serious hypersensitivity reactions, such as anaphylaxis, angioedema, rash, and urticaria have been reported with ezetimibe or bempedoic acid. - Hyperuricemia: Bempedoic acid, a component of NEXLIZET, may increase blood uric acid levels, which may lead to gout. Hyperuricemia may occur early in treatment and persist throughout treatment, returning to baseline following discontinuation of treatment.
Because of the potential for serious adverse reactions in a breast-fed infant, breastfeeding is not recommended during treatment with NEXLETOL. - Report pregnancies to Esperion Therapeutics, Inc.
