Evaluating the Efficacy and Safety of GB08 Injection in Pediatric Patients With Growth Hormone Deficiency

This study aims to evaluate the efficacy and safety of GB08 injection compared to Norditropin NordiFlex in pediatric patients with growth hormone deficiency (PGHD). It seeks to resolve the following questions: * 1: Does GB08 injection demonstrate comparable efficacy in treating PGHD at 24 weeks compared to Norditropin NordiFlex? * 2: Which dose (0.4 mg/kg, 0.8 mg/kg, and 1.2 mg/kg) of GB08 injection best balances efficacy and safety in treating PGHD at 24 weeks? * 3: Does GB08 injection maintain its efficacy in treating PGHD at 52 weeks compared to Norditropin NordiFlex? To achieve these, GB08 injection will be compared to Norditropin NordiFlex to see if it provides a more effective or safer treatment option for PGHD. This is a Phase II/III, Seamless, Multicenter, Randomized, Open-Label, Positive-Comparator Controlled Clinical Trial with two stages. Stage 1 answers questions #1 and #2 by comparing the efficacy and safety of GB08 injection and Norditropin NordiFlex intervention among PGHD at 24 weeks. It involves four groups (n=16 each): GB08 0.4 mg/kg, GB08 0.8 mg/kg, GB08 1.2 mg/kg, and Norditropin NordiFlex 0.035 mg/kg. GB08 and Norditropin NordiFlex will be administered once weekly and once daily, respectively. The primary outcome measurement is annualized height velocity (AHV) at 24 weeks. Other measurements include growth hormone levels, safety parameters, immunogenicity markers, and pharmacokinetic/pharmacodynamic profiles. The optimal GB08 dose will be further investigated in Stage 2, which answers question #3. At this stage, PGHD patients will randomly receive either GB08 injection or Norditropin NordiFlex intervention for 52 weeks (n=102 for each). After that, the efficacy and safety of GB08 will also be detected.

Effect of GH on the Blastocyst Euploid Rate in AMA Patients

This randomized trial aims to compare the euploid rate of blastocysts in AMA patients undergoing PGT-A (preimplantation genetic testing for aneuploidy) with or without growth hormone supplement. Infertile patients ≥38 years old will be recruited for study after informed consent if they fulfill the inclusion criteria and do not have the exclusion criteria. Eligible women will be randomised into one of the two groups: Treatment group: Women will receive growth hormone (GH) supplement before and during antagonist protocol for ovarian stimulation. Control group: Women will receive antagonist protocol for ovarian stimulation. The primary outcome is the euploidy rate of blastocysts.
