Un fármaco de edición genética reduce el colesterol malo un 62 por ciento en un ensayo

Una terapia experimental llamada VERVE-102 redujo el colesterol LDL hasta en un 62 por ciento tras una sola dosis en un estudio preliminar de seguridad. Los resultados provienen de un ensayo de fase I en el que participaron 35 pacientes con colesterol alto o enfermedad cardiovascular temprana. Los datos se publicaron esta semana en el New England Journal of Medicine.

Los investigadores informaron que el tratamiento parecía seguro, sin efectos secundarios graves, incluso con la dosis más alta. Los participantes experimentaron solo un aumento leve y temporal de las enzimas hepáticas. El fármaco utiliza ARNm encapsulado en nanopartículas para editar el gen PCSK9 en las células hepáticas, lo que reduce de forma permanente la producción de una proteína que aumenta los niveles de LDL.

Scientists at UT Southwestern Medical Center report they have identified a protein, HELZ2, that acts as a key regulator of how many cholesterol-carrying particles the liver releases into the bloodstream by affecting the gene APOB. The study was published in the American Heart Association journal Circulation and could inform future research into heart disease and fatty liver disease.

An experimental oral pill called enlicitide lowered LDL cholesterol by about 60% in a large phase three clinical trial, according to results published in The New England Journal of Medicine. The trial, led by Dr. Ann Marie Navar at UT Southwestern Medical Center and sponsored by Merck, involved 2,909 participants mostly already on statins. If approved, the daily pill could improve access to effective cholesterol treatment.

Researchers from the University of Barcelona and the University of Oregon report that short DNA molecules known as polypurine reverse Hoogsteen hairpins (PPRHs) suppressed the PCSK9 gene and reduced blood cholesterol in a mouse model. In transgenic mice carrying the human PCSK9 gene, a single injection of one candidate (HpE12) cut plasma PCSK9 by 50% and total cholesterol by 47% three days later, according to findings published in Biochemical Pharmacology.

Researchers in Australia have found that a mysterious FDA-approved drug, called compound X, removes toxic alpha-synuclein proteins from the brains of mice with Parkinson's-like symptoms. The treatment improved the animals' balance and mobility by enhancing the brain's glymphatic waste disposal system. The findings were presented at a symposium in the UK.

A large review of cardiovascular outcome trials found that people taking GLP-1 receptor agonists—drugs that include semaglutide (sold as Ozempic)—had a lower risk of major heart-related events than those given placebo. The analysis pooled results from 11 trials involving more than 90,000 participants, with an average follow-up of nearly three years, and reported benefits across patient subgroups including those with and without diabetes.
