Clinical trials

This study aims to preliminarily evaluate the efficacy and safety of GB10 intravitreal (IVT) injection for the treatment of patients with neovascular age-related macular degeneration (nAMD). It consists of two parts, single-ascending-dose escalation (SAD) and multiple-ascending-dose escalation (MAD). In SAD, a single IVT of up to 6 doses will be administered to up to 36 treatment-naïve or previously treated patients with nAMD. If the lowest dose is considered safe without dose-limiting toxicity, escalation will proceed to the next higher dose level. At the end of SAD, the two doses that best balance efficacy and safety will be selected and entered into MAD. In MAD, a single IVT of 2 doses will be administered to 12 treatment-naïve or previously treated patients with nAMD, who will be enrolled across the low- to high-dose levels. After GB10 intervention, the participants will undergo tests to evaluate the PK/PD characteristics of GB10 and ocular and non-ocular safety.

This study is a first-in-human, randomized, double-blind, placebo-controlled, dose-escalation trial in healthy adult participants to evaluate the safety, tolerability, PK, PD, and immunogenicity of GB18. A total of 36 healthy participants will be enrolled, including 5 dose cohorts (A1-A5) of 50 mg, 100 mg, 200 mg, 400 mg and 600 mg, with 4 participants in Cohort A1, and 8 participants per following cohorts (A2-A5). Participants in each cohort will be randomized to receive GB18 or placebo. The arms of this study include: To evaluate the safety and tolerability of GB18 following a single subcutaneous (SC) administered dose in healthy adult participants. To characterize the serum pharmacokinetics (PK) of GB18 following a single SC administered dose in healthy adult participants. To characterize the pharmacodynamics (PD) of a single SC administration of GB18 on circulating GDF15 concentrations in healthy adult participants. To evaluate the immunogenicity profile of GB18 in healthy adult participants. To evaluate the effect of GB18 on body weight in healthy adult participants. To preliminary evaluation of the relationship between GB18 serum concentration and QTc interval after a single SC administration in healthy adult participants.

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.
