Gene-editing trial shows yearlong cholesterol reduction in small study

A updated pilot study in The New England Journal of Medicine shows a single CRISPR infusion cut cholesterol levels by roughly 50% over 12 months in four high-dose patients.

The short version

  • An updated pilot study showed that a one-time gene-editing treatment sustained a roughly 50% drop in LDL cholesterol and triglycerides over a full year in four patients on the highest tested dose.
  • The early-stage trial evaluated 15 individuals with severe high cholesterol that had not responded to traditional medications.
  • Researchers reported no adverse effects in the four high-dose participants, suggesting the single-dose CRISPR-Cas9 infusion is safe and durable in early testing.
  • Larger clinical trials are required to confirm the therapy's safety, efficacy, and long-term viability before it can become widely available.

Key facts

  • A pilot study involving 15 patients evaluated five different doses of an experimental CRISPR-Cas9 gene-editing treatment for severe high cholesterol.[Slashdot]
  • Four patients who received the highest dose experienced an approximately 50% reduction in LDL cholesterol and triglycerides that persisted for a year.[Slashdot]
  • Researchers reported no adverse effects among the four participants in the highest dose group.[Slashdot]
  • The updated trial findings were published in The New England Journal of Medicine by researchers affiliated with the Cleveland Clinic.[Slashdot]

What remains uncertain

  • Whether the treatment remains safe and effective across larger and more diverse patient populations remains to be determined through future clinical trials.[Slashdot]
  • The full multi-year durability of the single-dose treatment beyond the 12-month study window is currently unknown.[Slashdot]
