MIMRYLO Solution for injection Ref.[116914] Active ingredients: Rusfertide

MIMRYLO (rusfertide) for injection, for subcutaneous use, a hepcidin mimetic, is a synthetic cyclic peptide (disulfide) isolated as an acetate salt. The chemical name for rusfertide is S ⁶,S ¹⁶cyclo[N-isovaleryl-Asp-Thr-His-Phe-Pro-Cys-IleNε-(N-palmitoyl-γ-Glu)-Lys-Phe-Glu-Pro-Arg-Ser-Lys-Gly-Cys-Lys-NH₂] acetate.

Rusfertide acetate has the following chemical structure:

Rusfertide acetate is an amorphous white to off-white powder, light sensitive and hygroscopic with low solubility in ethanol or acetonitrile. The aqueous solubility in pH range of 2.5 to 7.4 is ≥112 mg/mL.

The average molecular weight for the free base is 2442.0 u. The molecular formula for the free base is C₁₁₄H₁₈₁N₂₇O₂₈S₂.

MIMRYLO for injection is supplied as a sterile, preservative-free, white to off-white lyophilized powder in a single-dose glass vial. The 9.5 mg dose strength delivers 9.5 mg of rusfertide (provided as rusfertide acetate), mannitol (25 mg), sodium acetate trihydrate (1.36 mg), and glacial acetic acid/sodium hydroxide for pH adjustment, for subcutaneous injection after reconstitution with the provided diluent. The 19 mg, 28 mg, 41 mg, and 54 mg dose strengths deliver 19 mg, 28 mg, 41 mg and 54 mg of rusfertide (provided as rusfertide acetate), mannitol (20 mg), sodium acetate trihydrate (1.36 mg), and glacial acetic acid/sodium hydroxide for pH adjustment, for subcutaneous injection after reconstitution with the provided diluent.

The diluent for MIMRYLO is a sterile, preservative-free solution containing sodium acetate trihydrate (1.36 mg/mL), zinc acetate dihydrate (2.2 mg/mL), and glacial acetic acid for adjusting the pH to nominal pH of 5.4 in Water for Injection, USP. It is a clear, colorless solution, free from visible particles, and is provided in a glass prefilled syringe.

After reconstitution, MIMRYLO is a clear and colorless solution free from visible particles.
