Clinical Studies

Skyhawk is advancing RNA-targeted small molecule therapies into the clinic, with a focus on diseases of high unmet need.

Phase 2/3

SKY-0515 — FALCON-HD Trial

Huntington's Disease

About the Trial

The FALCON-HD trial is a global Phase 2/3 study evaluating SKY-0515, an oral small molecule designed to reduce mutant huntingtin (HTT) protein in patients with Huntington's Disease. SKY-0515 works by modifying the splicing of the HTT mRNA, reducing the production of the toxic mutant protein.

Phase 1 data demonstrated a 62% reduction in mutant HTT protein levels in cerebrospinal fluid, along with clinically meaningful improvements in cUHDRS at 3, 6, and 9 months of treatment.

Key Results

  • 62% reduction in mutant HTT protein (CSF)
  • cUHDRS improvement at 3, 6 and 9 months
  • Continued safety in ongoing Phase 1C patient study
  • Oral, once-daily small molecule administration
  • TGA (Australia) and global regulatory approvals obtained
