Alhemo(Concizumab) Instructions:Uses,Dosage, Side Effects

Alhemo is a novel prophylactic treatment for adult and pediatric patients aged 12 years and older with hemophilia A or B, specifically in those with inhibitors to FVIII or FIX. As a tissue factor pathway inhibitor (TFPI) antagonist, it works by modulating the clotting cascade to prevent bleeding episodes in these high-risk patients. Alhemo’s formulation, administered subcutaneously, ensures a regular dosing regimen with individualized adjustments based on plasma concentration levels.

This medication provides a vital therapeutic option for hemophilia patients who are resistant to traditional clotting factor treatments, offering hope for improved disease management and quality of life.

The pH of the solution is adjusted to 6.0 using hydrochloric acid and sodium hydroxide.

Dosage and Administration

Alhemo should be administered by subcutaneous injection to the abdomen or thigh, with daily rotation of injection sites. The recommended dosing regimen is as follows:

- Day 1: Loading dose of 1 mg/kg

- Day 2 and onwards: Once-daily dose of 0.2 mg/kg until the dose is individualized based on plasma concentration measurements.

After 4 weeks of treatment, plasma concentration of concizumab-mtci should be measured before the next dose using an enzyme-linked immunosorbent assay (ELISA).
