Lonapegsomatropin-tcgd
Generic Name: lonapegsomatropin-tcgd
Brand Names:
Skytrofa
11 DESCRIPTION Lonapegsomatropin-tcgd is a long-acting prodrug of a human growth hormone (somatropin) produced by recombinant DNA technology using E. coli . Lonapegsomatropin-tcgd consists of a parent drug, somatropin, that is conjugated to a methoxypolyethylene glycol carrier (4 × 10 kDa mPEG) via a proprietary TransCon Linker and has a molecular weight of 63 kDa (released somatropin is 22 kDa). In vitro assay confirms the minimum potency of released somatropin is NLT 2.5 IU/mg.

Uses
1 INDICATIONS AND USAGE SKYTROFA (lonapegsomatropin-tcgd) is a human growth hormone indicated for the: Treatment of pediatric patients 1 year and older who weigh at least 11.5 kg and have growth failure due to inadequate secretion of endogenous growth hormone (GH). Replacement of endogenous growth hormone in adults with growth hormone deficiency (GHD). SKYTROFA is a human growth hormone indicated for: Pediatric Patients: Treatment of pediatric patients 1 year and older who weigh at least 11.5 kg and have growth failure due to inadequate secretion of endogenous growth hormone (GH) ( 1 ). Adults: Replacement of endogenous growth hormone in adults with growth hormone deficiency (GHD) ( 1 ).
Dosage
2 DOSAGE AND ADMINISTRATION SKYTROFA should be administered subcutaneously once weekly into the abdomen, buttock, or thigh with regular rotation of the injection sites ( 2.7 ). Pediatric Patients: Recommended dose is 0.24 mg/kg body weight once weekly ( 2.2 ). Adults: Recommended starting dose is based on age and concomitant use of oral estrogen. Titrate monthly until the desired clinical response and/or weekly average IGF-1 concentration are achieved ( 2.3 ). See Full Prescribing Information for instructions on preparation and administration of drug ( 2.5 , 2.6 , 2.7 ). 2.1 General Dosing Information For subcutaneous injection, once weekly.
Side Effects
6 ADVERSE REACTIONS The following important adverse reactions are described elsewhere in the labeling: Increased mortality in patients with acute critical illness [see Warnings and Precautions (5.1) ] Severe hypersensitivity [see Warnings and Precautions (5.2) ] Increased risk of neoplasms [see Warnings and Precautions (5.3) ] Glucose intolerance and diabetes mellitus [see Warnings and Precautions (5.4) ] Intracranial hypertension [see Warnings and Precautions (5.5) ] Fluid retention [see Warnings and Precautions (5.6) ] Hypoadrenalism [see Warnings and Precautions (5.7) ] Hypothyroidism [see Warnings and Precautions (5.8) ] Slipped capital femoral epiphysis in pediatric patients [see Warnings and Precautions (5.9) ] Progression of preexisting scoliosis in pediatric patients [see Warnings...
Interactions
7 DRUG INTERACTIONS Table 4 includes a list of drugs with clinically important drug interactions when administered concomitantly with SKYTROFA and instructions for preventing or managing them. Table 4: Clinically Important Drug Interactions with SKYTROFA Replacement Glucocorticoid Treatment Clinical Impact: Microsomal enzyme 11β-hydroxysteroid dehydrogenase type 1 (11βHSD-1) is required for conversion of cortisone to its active metabolite, cortisol, in hepatic and adipose tissue. Somatropin inhibits 11βHSD-1. Consequently, individuals with untreated growth hormone deficiency (GHD) have relative increases in 11βHSD-1 and serum cortisol. Initiation of SKYTROFA may result in inhibition of 11βHSD-1 and reduced serum cortisol concentrations.
Warnings
5 WARNINGS AND PRECAUTIONS Severe Hypersensitivity: Hypersensitivity reactions, including anaphylaxis and angioedema have occurred. In the event of an allergic reaction, seek prompt medical attention ( 5.2 ). Increased Risk of Neoplasms: Monitor patients with preexisting tumors for progressions or recurrence. Increased risk of a second neoplasm in childhood cancer survivors treated with somatropin – in particular meningiomas in patients treated with radiation to the head for their first neoplasm ( 5.3 ). Glucose Intolerance and Diabetes Mellitus: May be unmasked. Periodically monitor glucose levels in all patients. Doses of concurrent antihyperglycemic drugs in diabetics may require adjustment ( 5.4 ). Intracranial Hypertension: Exclude preexisting papilledema. 4 CONTRAINDICATIONS SKYTROFA is contraindicated in patients with: Acute critical illness after open heart surgery, abdominal surgery or multiple accidental trauma, or those with acute respiratory failure due to the risk of increased mortality with use of pharmacologic doses of somatropin [see Warnings and Precautions (5.1) ] . Hypersensitivity to somatropin or any of the excipients in SKYTROFA.
Pregnancy
8.1 Pregnancy Risk Summary There are no available data on lonapegsomatropin-tcgd use in pregnant patients to evaluate a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. Available published data over several decades for somatropin, the active component of lonapegsomatropin-tcgd, have not identified a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes.
Storage
Storage and Handling For patients : Refrigerate SKYTROFA cartridges at 36°F to 46°F (2°C to 8°C) in the outer carton to protect from light until the expiration date. Do not freeze. Alternatively, SKYTROFA outer carton containing blistered cartridges may be stored at room temperature [up to 86°F (30°C)] for up to 6 months and can be returned to refrigeration within the 6 months.
