Rezafungin (Rezzayo) vs Sincalide (Kinevac)

An educational, source-based comparison of Rezafungin (Rezzayo) and Sincalide (Kinevac) — how each peptide works, what it's researched for, and what to know before going deeper.

Echinocandin · Antifungal
Rezafungin (Rezzayo)

Once-weekly echinocandin for candidemia and invasive candidiasis.

Mechanism

Next-generation echinocandin structurally related to anidulafungin with enhanced stability, inhibiting β-(1,3)-D-glucan synthase; long half-life permits once-weekly IV dosing.

Research areas
  • Candidemia
  • Invasive candidiasis
Considerations
  • FDA-approved (2023).
  • Infusion reactions and photosensitivity reported.

CCK Analog · Diagnostics
Sincalide (Kinevac)

Synthetic C-terminal octapeptide of cholecystokinin for gallbladder imaging.

Mechanism

Synthetic CCK-8 that binds CCK-A receptors on gallbladder smooth muscle, triggering contraction; used to assess gallbladder ejection fraction in cholescintigraphy.

Research areas
  • Gallbladder ejection fraction (HIDA scan)
  • Pancreatic secretion testing
  • Small bowel transit imaging
Considerations
  • FDA-approved.
  • Abdominal cramping, nausea, diarrhea common; contraindicated in suspected gallstone obstruction.
