What this trial studies

This pilot study investigates the safety and efficacy of geranylgeraniol supplementation in patients with mevalonate kinase deficiency, a rare genetic disorder that disrupts the mevalonate pathway and leads to autoinflammatory responses. The study includes a pre-supplementation period to assess inflammation and clinical status, followed by three months of supplementation with 150 mg of geranylgeraniol daily. The goal is to mitigate the deficiency of isoprenoids that contribute to the disease's symptoms and improve patient outcomes.

Who should consider this trial

Good fit: Ideal candidates are patients aged 12 years and older with genetically confirmed mevalonate kinase deficiency in good clinical status.

Not a fit: Patients under 12 years old will not benefit from this study.

Why it matters

Potential benefit: If successful, this supplementation could reduce inflammation and improve the clinical status of patients with mevalonate kinase deficiency.

How similar studies have performed: While this approach is novel for mevalonate kinase deficiency, similar studies on isoprenoid supplementation have shown promise in related conditions.
