  • Polypeptides are susceptible to denaturation or enzymatic degradation in the blood, liver, or kidney. Accordingly, polypeptides typically have short circulatory half-lives of several hours. Because of their low stability, peptide drugs are usually delivered in a sustained frequency so as to maintain an effective plasma concentration of the active peptide. Moreover, since peptide drugs are usually administered by infusion, frequent injection of peptide drugs causes considerable discomfort to a subject.
  • Serum half-life is an empirical characteristic of a molecule and must be determined experimentally for each new potential drug.

  • Somatrogon is a long-acting recombinant human growth hormone (rhGH) comprising the amino acid sequence of human growth hormone and 3 copies of the carboxy -terminal peptide of human chorionic gonadotropin (SEQ ID NO:2), with a half-life that permits once weekly (QW) administration (Fares et ah, Int. J. Cell Biol. (2011) 275063; Fares et ah, Proc. Nat. Acad. Sci. USA (1992) 89(10):4304-8).

  • AEs Adverse events
  • injection site reactions were assessed at each study visit, with the exception of injection site reactions, which were not assessed at predose visits; subjects were also trained to record injection site reactions in a diary.
  • PK and PD assessments For subjects in the somatrogon group, blood samples were collected 12 to 120 hours post dose for analysis of serum somatrogon and IGF-1 in accordance with sampling sub-blocks. For each of the 3 dose groups, 2 samples were collected at different times after administration of the second dose, with a total of 6 samples collected for each subject. Median concentrations were calculated for each dose using naive pooled estimate at each time point. Subjects who received Genotropin had blood samples collected regularly over the study period. Assessment of anti-drug antibodies (AD As) against somatrogon and Genotropin were performed at protocol-specified time points by Eurofms Pharma Bioanalytics Services US Inc.

  • AEs including injection-site reactions
  • Any injection-site reactions that met the criteria for “abnormal” were assessed as AEs.
  • An abnormal injection-site reaction was defined as a reaction that was moderate to severe in intensity, required medical attention, was deemed abnormal by an investigator, or had a pain score >4, based on the protocol-specified Pain Assessment Scale (ranging from 0 [“no hurt”] to 5 [“hurts worse”]).

  • Study Participants 65 subjects were screened and 44 subjects randomized at 24 sites in Japan; of the 44 dosed subjects, 43 completed the 12-month main study, and 1 subject in the Genotropin® group discontinued from the study due to an AE (craniopharyngioma). Demographic and baseline characteristics were similar between the 2 treatment groups (somatrogon and Genotropin®), with most (70%) subjects aged between 3 and 7 years. Approximately half (47.7%) of the subjects were male.
  • Efficacy The least squares (LS) mean of height velocity (HV) at Month 12 was 9.65 cm/y in the somatrogon group and 7.87 cm/y in the Genotropin® group; similar results were observed for annualized HV at Month 6. LS mean treatment difference of +1.79 cm/y (95% Cl: 0.97-2.60) in HV at Month 12 was greater than the pre-established margin of -1.8 cm/y, demonstrating QW somatrogon was comparable to QD Genotropin®.

  • Mean IGF-1 SDS values in the Genotropin® group ranged from -0.59 to -0.25 SDS at all post-baseline visits.
  • PK/PD Peak serum concentrations of somatrogon were achieved at 12 hours to 18 hours after dosing, and the maximum concentration of somatrogon increased with increasing dosage. The calculated median concentrations of IGF-1, IGF-1 SDS, and IGFBP-3 based on sparse sampling showed that somatrogon treatment resulted in an IGF-1 and IGFBP-3 response. Median IGF-1 standard deviation scores (SDS) did not exceed +2 through the course of the week or at regular study visits over 12 months (FIG. 11).
  • TEAEs The most common all-causality TEAEs were nasopharyngitis (somatrogon: 54.5%; Genotropin®: 50.0%), injection site pain (somatrogon: 72.7%; Genotropin®: 13.6%), influenza (somatrogon: 27.3%; Genotropin®: 27.3%), pyrexia (somatrogon: 18.2%; Genotropin®: 13.6%), and pharyngitis (somatrogon: 13.6%; Genotropin®: 18.2%); the majority of TEAEs were mild to moderate in severity (somatrogon: 90.9%; Genotropin®: 77.3%).

  • SAE serious adverse event.
  • SAEs are based on the investigator's assessment. a Subjects who have an AE record that indicates that the AE caused the subject to be discontinued from the study. b Subjects who have an AE record that indicates that action taken with study treatment was drug withdrawn but AE did not cause the subject to be discontinued from study.
  • Immunogenicitv A total of 18/22 subjects in the somatrogon group and 4/22 subjects in the Genotropin® group tested positive for AD As during the 12-month treatment period. Most subjects in the somatrogon group who tested positive for AD As had AD As that were specific for the hGH component of somatrogon. Two subjects in the somatrogon group tested positive for neutralizing antibodies (nAbs) against somatrogon at a single visit but were negative for all subsequent visits. None of the subjects in the Genotropin® group tested positive for nAbs.
  • Somatrogon administered once weekly was concluded as being comparable to Genotropin® administered once daily as the mean treatment difference (somatrogon- Genotropin®) in HV was +1.79 cm/year (95% Cl, 0.97-2.60), which was greater than the pre- established margin of-1.8 cm/year.
  • the somatrogon group had higher HV at 12 months (9.65 cm/year vs 7.87 cm/year) and showed a greater improvement in height SDS from baseline to 12 months (0.94 vs 0.52). Both treatment groups showed similar changes in bone maturation; advancement in bone age did not exceed advancement in chronological age.
  • Nonadherence may reduce the efficacy of GH treatment, resulting in suboptimal growth responses and reduced HV and final adult height (Graham et al., Patient Prefer. Adherence (2020) 14:1889-99). Reducing the number of rhGH injections required is likely to significantly lower the treatment burden associated with GH treatment, which may encourage greater adherence in patients and caregivers. As such, somatrogon administered once weekly may alleviate many of the issues associated with compliance with once-daily Genotropin.
  • somatrogon group had a higher incidence of injection-site pain compared with the Genotropin group, subjects may prefer to receive 1 injection of somatrogon compared with 7 injections of Genotropin during the course of a week. This is supported by a discrete choice experiment conducted in Japanese children with GHD, which found a clear preference for a once-weekly injection schedule instead of a once- daily injection schedule (Tanaka et al., Pediatr. Int. (2021)). Although the use of once-weekly somatrogon may improve adherence among patients with GHD, it is possible that some patients with poor adherence to daily GH treatment (e.g., adolescents) will also show poor adherence to long-acting treatments such as once-weekly somatrogon.
  • IGF-1 concentrations may be monitored to assess compliance and response to treatment.
  • daily rhGH there is no concern about the time after dose for collection of samples because the peaktrough ratios are small and any observations are reflective of what would be observed over the dosing interval.
  • once-weekly treatment as was shown in this study, the peak:trough variability is larger.
  • a PK/PD analyses performed on the Phase 2 study and showed that mean IGF-1 SDS over the 1-week dosing interval was best approximated by IGF-1 assessments 4 days (96 hours) after dose administration (Fisher et al., Horm. Res.
  • This Example illustrates patient counseling information to be provided to the patient and/or caregiver when administering long-acting rhGH, contraindications, warnings and precautions, drug interactions, and use in specific populations.
  • Patient Counseling Advise the patient and/or caregiver to read the FDA-approved patient labeling (Patient Information and Instructions for Use).
  • Adrenal Cortical Hypofunction hypoadrenalism may develop in patients who have or who are at risk for pituitary hormone deficiency(s). Advise patients/caregivers that if hyperpigmentation, extreme fatigue, dizziness, weakness, or weight loss is experienced during treatment with somatrogon to report this to their healthcare provider.
  • Thyroid Function undiagnosed/untreated hypothyroidism may prevent an optimal response to the long-acting rhGH. Advise patients/caregivers that periodic thyroid function tests may be required during treatment with the long-acting rhGH.
  • Benign Intracranial Hypertension advise patients/caregivers to report any visual changes, headache, and nausea and/or vomiting to their healthcare provider.
  • Hypersensitivity Reaction advise patients/caregivers that serious systemic hypersensitivity reactions (anaphylaxis and angioedema) are possible and that prompt medical attention should be sought if an allergic reaction occurs.
  • Glucose Metabolism advise patients/caregivers that new onset of insulin resistance and hyperglycemia may occur and monitoring of blood glucose during treatment with the long- acting rhGH in patients with glucose intolerance or who have risk factors for diabetes, may be needed.
  • Active Malignancy Based on experience with daily growth hormone products, long- acting rhGH is contraindicated in patients with active malignancy.
  • Acute Critical Illness Based on experience with pharmacologic amounts of daily growth hormone products, long-acting rhGH is contraindicated in patients with acute critical illness due to complications following open heart or abdominal surgery, multiple accidental trauma, or acute respiratory failure.
  • Hypersensitivity The long-acting rhGH is contraindicated in patients with known hypersensitivity to the long-acting rhGH or any of its excipients.
  • Acute Critical Illness Treatment with pharmacologic amounts of daily growth hormone products has been associated with increased mortality in patients with acute critical illness due to complications following open heart surgery, abdominal surgery or multiple accidental trauma, or those with acute respiratory failure. Based on experience with daily growth hormone products, if patients who are receiving the long-acting rhGH therapy become acutely critically ill, the potential benefit of continued treatment should be weighed against the potential risk.
  • Glucose Metabolism Treatment with daily growth hormone products may induce a state of insulin resistance and hyperglycemia. Additional monitoring should be considered in patients treated with the long-acting rhGH who have glucose intolerance, or additional risk factors for diabetes. In patients treated with the long-acting rhGH who have diabetes mellitus, anti-diabetic therapy may require adjustment.
  • IH Intracranial hypertension
  • papilledema Intracranial hypertension
  • visual changes headache, nausea, and/or vomiting
  • Symptoms usually occurred within the first 8 weeks after the initiation of daily growth hormone therapy.
  • IH-associated signs and symptoms rapidly resolved after cessation of therapy or a reduction of the daily growth hormone dose.
  • the long-acting rhGH should be temporarily discontinued in patients with clinical or fundoscopic evidence of IH.
  • Hypersensitivity Reactions Serious systemic hypersensitivity reactions (e.g., anaphylaxis, angioedema) have been reported with daily growth hormone products. If a serious hypersensitivity reaction occurs, immediately discontinue use of the long-acting rhGH therapy; treat promptly per standard of care and monitor until signs and symptoms resolve. Do not use in patients with previous hypersensitivity to the long-acting rhGH therapy.
  • Adrenal Cortical Hypofunction Based on published data patients receiving daily growth hormone therapy 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 the long-acting rhGH therapy treatment. Monitor patients for reduced serum cortisol levels and/or need for glucocorticoid dose increases in those with known hypoadrenalism.
  • Thyroid Function Based on experience with daily growth hormone products, undiagnosed/untreated hypothyroidism may prevent an optimal response to the long-acting rhGH therapy. During the long-acting rhGH therapy, thyroid function should be monitored as indicated based on clinical evaluation.
  • Epiphyseal disorders including slipped capital femoral epiphysis, may occur more frequently in patients with endocrine disorders or in patients undergoing rapid growth. Any pediatric patient with the onset of a limp or complaints of hip or knee pain during treatment should be carefully evaluated.
  • Glucocorticoids In patients receiving concomitant the long-acting rhGH therapy and glucocorticoid treatments, glucocorticoid dosing should be carefully monitored to avoid both hypoadrenalism and an inhibitory effect on growth.
  • the microsomal enzyme 11 b-hydroxysteroid dehydrogenase type 1 (1 l HSD-l) is required for conversion of cortisone to its active metabolite, cortisol, in hepatic and adipose tissue.
  • Treatment with daily growth hormone products inhibits IIbHd ⁇ -I, reducing serum cortisol concentrations, which may unmask previously undiagnosed central (secondary) hypoadrenalism or render low glucocorticoid replacement doses ineffective.
  • Patients treated with cortisone acetate and prednisone may be affected more than others because conversion of these drugs to their biologically active metabolites is dependent on the activity of l ⁇ HSD-l.
  • Insulin and/or Oral/Injectable Hypoglycemic Agents In patients with diabetes mellitus requiring drug therapy, the dose of insulin and/or oral/injectable agent may require adjustment when the long-acting rhGH therapy is initiated.
  • Lactation The long-acting rhGH therapy should be administered to lactating women only if clearly needed.
