Indications
FORZINITY is indicated to improve muscle strength in adult and pediatric patients with Barth syndrome weighing at least 30 kg. This indication is approved under accelerated approval based on an improvement in knee extensor muscle strength, an intermediate clinical endpoint [see Clinical Studies (14) ] . Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

( 1 ) This indication is approved under accelerated approval based on an improvement in knee extensor muscle strength, an intermediate clinical endpoint. ( 14 ) Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).
Contraindications
Serious hypersensitivity to elamipretide or any of the excipients in FORZINITY [see Warnings and Precautions (5.2) ]. Serious hypersensitivity to any of the ingredients ( 4 , 5.2 )
Warnings and precautions
Benzyl alcohol toxicity : Do not use in neonates. ( 5.1 )
5.1Risk 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) .]
5.2Hypersensitivity
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) ] . Reactions may occur within minutes to months after treatment initiation.
