                Slipped capital femoral epiphysis may occur more frequently in patients undergoing rapid growth; evaluate patients with onset of a limp or complaints of persistent hip or knee pain

                Somatrogon increases growth rate, and progression of preexisting scoliosis can occur in patients who experience rapid growth; growth hormone treatment has not been shown to increase occurrence of scoliosis; monitor patients with history of scoliosis for disease progression

                Pancreatitis reported; risk may be greater in pediatric patients compared with adults; consider pancreatitis in patients who develop persistent severe abdominal pain

                Lipoatrophy may occur when administered SC at the same site over a long period of time; rotate injection sites to reduce risk

                Serum levels of phosphorus, alkaline phosphatase, and parathyroid hormone may increase; monitor as appropriate

                Increased mortality with acute critical illness

                • Increased mortality in patients with acute critical illness owing to complications following open heart surgery, abdominal surgery, or multiple accidental trauma, or those with acute respiratory failure has been reported

                • Severe hypersensitivity reactions, including anaphylaxis and angioedema, reported
                • Inform patients and/or caregivers about possibility of hypersensitivity and to seek prompt medical attention if an allergic reaction occurs

                Risk of neoplasms

                • Active malignancy
                  • Increased risk of malignancy progression
                  • Any preexisting malignancy should be inactive, and its treatment completed before initiating therapy
                  • Discontinue somatrogon with evidence of recurrent malignancy
                • Risk of second neoplasm
                  • Increased risk of second neoplasm reported in childhood cancer survivors treated with radiation to the brain/head for their first neoplasm and who developed subsequent growth hormone deficiency (GHD) and were treated with somatropin
                  • Intracranial tumors, in particular meningiomas, were the most common of these second neoplasms
                  • Monitor for progression or recurrence of the tumor in all patients who have history of GHD secondary to an intracranial neoplasm while on somatrogon
                • New malignancy during treatment
                  • Consider risks and benefits in children with certain rare genetic causes of short stature since these children have an increased risk of developing malignancies

                • Symptoms usually occurred within 8 weeks after initiating
                • In all reported cases, IH-associated signs and symptoms rapidly resolved after cessation of therapy or a reduction of somatropin dose
                • Perform fundoscopic examination before initiating treatment to exclude preexisting papilledema and periodically thereafter
                • If papilledema identified before initiating, evaluate the etiology and treat underlying cause before initiating
                • Temporarily discontinue in patients with clinical or fundoscopic evidence of IH
                • If IH confirmed, restart treatment at a lower dose after IH-associated signs and symptoms have resolved

                Hypoadrenalism

                • Patients who have or are at risk for pituitary hormone deficiency(s) may be at risk for reduced serum cortisol levels and/or unmasking of central (secondary) hypoadrenalism
                • Patients treated with glucocorticoid replacement for previously diagnosed hypoadrenalism may require an increase in their maintenance or stress doses following initiation of somatrogon treatment
                • Monitor for reduced serum cortisol levels and/or need for glucocorticoid dose increases in those with known hypoadrenalism

                Hypothyroidism

                • Undiagnosed/untreated hypothyroidism may prevent an optimal response to somatrogon
                • In patients with GHD, central (secondary) hypothyroidism may first become evident or worsen during treatment with growth hormone therapy

                Pregnancy

                Data are unavailable on use in pregnant females to evaluate for a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes

                Pregnancy testing

                • Although somatrogon did not interfere with human chorionic gonadotropin (hCG) pregnancy testing in a limited number of commercial tests, interference with hCG blood and urine pregnancy testing in patients receiving somatrogon may be possible, leading to either false-positive or false-negative results
                • Alternative methods (ie, not reliant on hCG) are recommended to determine pregnancy

                Animal studies

                • In pregnant rats, there was no evidence of embryo-fetal toxicity following administration of somatrogon SC during organogenesis at doses up to 45 times the maximum recommended human dose based on exposure

                Lactation

                Data are unavailable on presence of somatrogon in human or animal milk, effects on breastfed infants, or effects on milk production

                Pregnancy Categories

                A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

                B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

                C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

                D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

                X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

                NA: Information not available.

                Mechanism of Action

                Long-acting human growth hormone derivative

                Binds to growth hormone (GH) receptor and initiates a signal transduction cascade culminating in changes in growth and metabolism

                This binding leads to activation of STAT5b signaling pathway and increases serum concentration of IGF-1

                GH and IGF-1 stimulate metabolic changes, linear growth, and enhance growth velocity in pediatric patients with GHD

                Absorption

                Peak plasma time: 11 hr (range 6-25 hr)

                Peak plasma concentration (steady state): 495 ng/mL

                Distribution

                Vd: 0.342 L/kg (central); 0.671 L/kg (peripheral)

                Metabolism

                Believed to be classic protein catabolism, with subsequent recovery of amino acids and return to systemic circulation

                Elimination

                Half-life: 37.7 hr

                Clearance: 0.0398 L/hr/kg

                Excretion: Not evaluated

                Discard if flakes, particles, or discoloration observed

                Do not shake; shaking can damage product

                See Prescribing Information for complete patient instructions for self or caregiver administration

                SC Administration

                Administer once weekly by SC injection on the same day each week, at any time of the day

                Administer in abdomen, thighs, buttocks, or upper arms; rotate injection site weekly

                If more than 1 injection required to deliver a complete dose, administer each injection at a different injection site

                Switching administration day

                • Day of weekly administration can be changed if necessary as long as time between 2 doses is ≥3 days
                • After selecting new dosing day, continue once-weekly dosing

                Switching from daily growth hormone

                • When switching from daily growth hormone, initiate once-weekly somatrogon on the day following last daily injection

                Missed dose

                • Administer as soon as possible within 3 days after missed dose
                • If >3 days have passed, skip missed dose and administer next dose on regularly scheduled day

                Storage

                Before first use (unused pens)

                • Refrigerate between 36-46ºF (2-8ºC) in original carton to protect from light
                • Do not freeze pen or expose it to heat
