Overview
11 DESCRIPTION FORZINITY contains elamipretide, a mitochondrial cardiolipin binder. Elamipretide is isolated as a hydrochloride salt that is freely soluble in water. The chemical name for elamipretide hydrochloride is L-Phenylalaninamide, D-arginyl-2,6-dimethyl-L-tyrosyl-L-lysyl-, hydrochloride (1:3). Its molecular formula is C 32 H 49 N 9 O 5 ∙3HCl and its molecular weight is 749.2. The structure of elamipretide hydrochloride is: All amino acid residues in FORZINITY have the L configuration except for arginine which has the D configuration. The peptide sequence is denoted as D-Arg-2,6-dimethyl-Tyr-Lys-Phe-NH 2 . FORZINITY is a ready-to-use sterile, clear, colorless to yellow aqueous solution supplied as single-patient-use vials containing 3.5 mL solution for subcutaneous injection. Each 0.5 mL dose of FORZINITY contains 40 mg of elamipretide (equivalent to 46.8 mg elamipretide hydrochloride), 10 mg benzyl alcohol as a preservative, and 2.07 mg monobasic sodium phosphate (as monohydrate). The product may contain hydrochloric acid or sodium hydroxide to adjust pH. The pH of FORZINITY solution is 4.7 to 6.1. Chemical Structure
How to use
For patients weighing 30 kg and greater, the recommended dosage is 40 mg subcutaneously once daily. ( 2.1 ) Reduce the dose in adults with severe renal impairment. ( 2.2 , 8.6 ). 2.1 Recommended Dosage The recommended dosage of FORZINITY in patients weighing at least 30 kg is 40 mg subcutaneously once daily. Patients should receive the dose at the same time each day. Missed Dose If a dose is missed, skip the dose and take the next dose of FORZINITY at the scheduled time. Do not take a double dose of FORZINITY. 2.2 Dosage Modifications For Renal Impairment Refer to Table 1 for dosage modifications in adults with renal impairment. Table 1: Recommended Dosage in Adults with Renal Impairment Estimated Glomerular Filtration Rate (eGFR) (mL/minute) Recommended Dosage Greater than or equal to 30 mL/minute 40 mg subcutaneously once daily Less than 30 mL/minute and NOT on dialysis 20 mg subcutaneously once daily There is insufficient information to recommend a dosage regimen in adults with eGFR less than 30 mL/minute and on dialysis. There is insufficient information to recommend a dosage regimen in pediatric patients weighing 30 kg or greater with renal impairment. 2.3 Important Administration Instructions FORZINITY is a clear, colorless to yellow aqueous solution that contains the preservative, benzyl alcohol. Visually inspect each vial of FORZINITY for particulate matter and…
Side effects
Most common adverse reactions are injection site reactions. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Stealth BioTherapeutics Inc. at 1-844-444-6486 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. In the FORZINITY clinical development program, 12 male patients aged 12 to 35 years with genetically-confirmed Barth syndrome received treatment with daily subcutaneous injections of 40 mg FORZINITY. Eleven of these 12 patients were Caucasian. Patients first participated in a double-blind, placebo-controlled crossover trial where they were randomized to one of two sequences: 12 weeks of FORZINITY in Period 1 then a 4-week washout followed by 12 weeks of placebo in Period 2 or 12 weeks of placebo in Period 1 then a 4-week washout followed by 12 weeks of FORZINITY in Period 2 Ten patients completed the randomized trial and entered the open-label extension period where they received FORZINITY once daily. Eight of these patients received FORZINITY for 168 weeks, three of whom received FORZINITY for a total of 192 weeks. Adverse reactions occurring more commonly on FORZINITY than on…
Warnings
Important safety information
Benzyl alcohol toxicity : Do not use in neonates. ( 5.1 ) 5.1 Risk of Benzyl Alcohol Toxicity in Neonates FORZINITY is not approved for use in neonates. Serious adverse reactions, including fatal reactions, of new onset or worsening metabolic acidosis that progressed to neurotoxicity, and in some cases gasping syndrome, have been reported in low-birth weight neonates (less than 2,500 grams) and preterm neonates (gestational age less than 34 weeks) who received benzyl alcohol (BA)-containing drugs intravenously. FORZINITY is not approved for intravenous use [see Dosage and Administration (2.1) ] . Gasping syndrome is a life-threatening condition in neonates caused by BA toxicity and is primarily characterized by multiorgan dysfunction secondary to metabolic acidosis, which leads to gasping respirations and death. The minimum amount of BA at which these serious adverse reactions, including fatal reactions, may occur is not known (FORZINITY contains 20 mg of BA per mL). [See Use in Specific Populations (8.4) .] 5.2 Hypersensitivity Hypersensitivity reactions, including serious allergic reactions requiring emergency medical intervention, have been reported in patients receiving FORZINITY. These reactions have included skin manifestations such as rash, papular lesions, and eczematous dermatitis, as well as respiratory symptoms including cough [see Adverse Reactions (6.1) ] .…
