LL-37 is the only human cathelicidin antimicrobial peptide and is studied in immune and antimicrobial research. Patients can request a telehealth evaluation through the TelosRX Telehealth Portal to discuss compounded access.

What Is LL-37?

LL-37 is a 37-amino-acid peptide derived from human cathelicidin. It is studied in preclinical research for antimicrobial and immune-modulating pathways.

LL-37 is not an FDA-approved drug. It is available through compounding pharmacies under valid prescription.

Common Discussion Points

Patients often raise LL-37 during evaluations for:

  • Antimicrobial pathway research interest
  • Immune modulation discussions
  • Skin and barrier research
  • Inflammation research applications

A licensed provider determines clinical appropriateness individually.

Pre-PCAC July 2026 Regulatory Context

LL-37 is under PCAC review ahead of the July 2026 meeting. Patients interested in compounded access should consult a licensed provider while it remains available.
