Tesamorelin
Generic Name: tesamorelin
Brand Names:
Egrifta Sv
11 DESCRIPTION Tesamorelin is a human growth hormone-releasing factor (GRF) analog produced synthetically. It is comprised of the 44 amino acid sequence of human GRF and a hexenoyl moiety, a C6 chain with a double bond at position 3, attached to the tyrosine residue at the N-terminal part of the molecule. Tesamorelin is prepared as an acetate salt.

Uses
1 INDICATIONS AND USAGE EGRIFTA SV is indicated for the reduction of excess abdominal fat in HIV-infected adult patients with lipodystrophy. Limitations of Use: Long-term cardiovascular safety of EGRIFTA SV has not been established. Consider risk/benefit of continuation of treatment in patients who have not had a reduction in visceral adipose tissue. EGRIFTA SV is not indicated for weight loss management as it has a weight neutral effect. There are no data to support improved compliance with anti-retroviral therapies in HIV-positive patients taking EGRIFTA SV. EGRIFTA SV is a growth hormone-releasing factor (GHRF) analog indicated for the reduction of excess abdominal fat in HIV-infected adult patients with lipodystrophy.
Dosage
2 DOSAGE AND ADMINISTRATION The recommendations in this prescribing information only apply to EGRIFTA SV (tesamorelin) for injection 2 mg per vial formulation. For recommendations for tesamorelin for injection 1 mg per vial formulation, see the EGRIFTA prescribing information. These two formulations and strengths have differences in the dosage, the number of vials required to prepare a dose, reconstitution instructions, and storage requirements. ( 2.1 ). The dose of EGRIFTA SV is 1.4 mg (0.35 mL of the reconstituted solution) injected subcutaneously once daily. ( 2.1 ) Inject EGRIFTA SV into the abdomen, rotating injection sites. ( 2.1 , 5.6 ) Use only the diluent provided, Sterile Water for Injection, to reconstitute EGRIFTA SV.
Side Effects
6 ADVERSE REACTIONS The following important adverse reactions are also described elsewhere in the labeling: Increased risk of neoplasms [see Warnings and Precautions ( 5.1 )] Elevated IGF-1 levels [see Warnings and Precautions ( 5.2 )] Fluid retention [see Warnings and Precautions ( 5.3 )] Glucose intolerance or diabetes mellitus [see Warnings and Precautions ( 5.4 )] Hypersensitivity reactions [see Warnings and Precautions ( 5.5 )] Injection site reactions [see Warnings and Precautions ( 5.6 )] Most commonly reported adverse reactions (>5%): Arthralgia, injection site erythema, injection site pruritus, pain in extremity, peripheral edema, and myalgia.
Interactions
7 DRUG INTERACTIONS Cytochrome P450-metabolized drugs : Monitor patients for potential interactions when administering with EGRIFTA SV . ( 7.1 ) Glucocorticoids : Patients receiving glucocorticoid replacement for previously diagnosed hypoadrenalism may require an increase in maintenance or stress doses following initiation of EGRIFTA SV. ( 7.2 ) 7.1 Cytochrome P450-Metabolized Drugs Co-administration of tesamorelin with simvastatin, a CYP3A substrate had no significant impact on the pharmacokinetics profiles of simvastatin in healthy subjects [see Clinical Pharmacology ( 12.3 )] . EGRIFTA SV stimulates GH production. Published data indicate that GH may modulate cytochrome P450 (CYP450) mediated antipyrine clearance.
Warnings
5 WARNINGS AND PRECAUTIONS Increased risk of neoplasms: Preexisting malignancy should be inactive and its treatment complete prior to starting EGRIFTA SV . Discontinue EGRIFTA SV if there is any evidence of recurrent malignancy. ( 5.1 ) Elevated IGF-1: EGRIFTA SV stimulates GH production and increases serum IGF-1, a growth factor. The effects of prolonged elevations in IGF-1 levels are unknown. Monitor IGF-1 levels during EGRIFTA SV therapy. Consider discontinuing in patients with persistent elevations. ( 5.2 ) Fluid retention: May occur with EGRIFTA SV and may include edema, arthralgia, and carpal tunnel syndrome. ( 5.3 ) Glucose intolerance or diabetes mellitus: May develop with EGRIFTA SV use. Evaluate glucose prior to and during therapy. 4 CONTRAINDICATIONS EGRIFTA SV is contraindicated in: Patients with disruption of the hypothalamic-pituitary axis ( 4 ) Patients with active malignancy ( 4 ) Patients with known hypersensitivity to tesamorelin or excipients in EGRIFTA SV ( 4 ) Pregnancy ( 4 ) EGRIFTA SV is contraindicated in: Patients with disruption of the hypothalamic-pituitary axis due to hypophysectomy, hypopituitarism, pituit...
Pregnancy
8.1 Pregnancy Risk Summary EGRIFTA SV is contraindicated in pregnant women because modifying visceral adipose tissue offers no benefit in pregnant women and could result in fetal harm [see Clinical Considerations and Contraindications ( 4 )] . Administration of tesamorelin acetate to rats during organogenesis resulted in hydrocephaly in offspring at a dose of approximately two and four times the clinical dose, based on measured drug exposure (AUC). If EGRIFTA SV is used during pregnancy, or if the patient becomes pregnant while taking it, discontinue EGRIFTA SV.
Storage
16 HOW SUPPLIED/STORAGE AND HANDLING EGRIFTA SV (tesamorelin) for injection is supplied as a white to off-white lyophilized powder in a 2 mg single-dose vial with a diluent of 10 mL vial of Sterile Water for Injection.
