Clinical trials

This is a multicenter, randomized, open-label, positive-controlled phase III confirmatory clinical study. A total of 84 children with short stature due to Turner Syndrome (TS) are planned to be enrolled. Stratified by age and karyotype, subjects will be randomized at a 1:1 ratio to either the test group or the positive control group with continuous treatment for 52 weeks. The study aims to compare the efficacy and safety of Inpegsomatropin-Injection versus Givopegsomatropin Solution Injection in children with TS-related short stature, so as to provide evidence for the new indication application of the investigational drug.

This is a multiple-dose, dose-escalation, randomized, double-blind, placebo-controlled phase Ⅱa clinical trial. A total of 36 adult participants with growth hormone deficiency will be enrolled sequentially in ascending dose cohorts, and within each dose cohort, participants will be randomized in a 3:1 ratio.

This study is a Phase Ib, multicenter randomized, double-blind, dose-escalation, placebo-controlled trial designed to evaluate the safety, tolerability, PK, and PD profiles of multiple-dose ACT500 in participants with metabolic dysfunction-associated steatotic liver disease (MASLD) complicated with chronic hepatitis B (CHB). The trial plans to enroll 24 participants with MASLD complicated with CHB across three dose cohorts initially, each consisting of 8 participants who will receive oral ACT500 tablets once daily.

This is a multicenter, randomized, open-label, active-controlled Phase III clinical trial to evaluate the efficacy and safety of Inpegsomatropin injection，once a week，compared with recombinant human growth hormone (rhGH) in children with short stature born small for gestational age (SGA).It plans to enroll 141 children with short stature born small for gestational age (SGA), who will be stratified by gender and age and randomized in a 1:1:1 ratio to either Experimental Group 1, Experimental Group 2, or the Active Control Group. All participants will undergo a screening period (up to 12 weeks), a treatment period (52 weeks), and a post-treatment follow-up period (5 weeks). Safety and efficacy will be comprehensively evaluated.

This study is a multicenter, open-label, dose-escalation trial designed to evaluate the safety, tolerability, PK, and PD profiles of ACT500 in participants with metabolic dysfunction-associated steatotic liver disease (MASLD). The trial plans to enroll approximately 24 MASLD participants across four dose cohorts, each consisting of 6 participants who will receive oral ACT500 once daily.

This is a multicenter, randomized, open-label, active-controlled Phase III clinical trial to evaluate the efficacy and safety of Inpegsomatropin injection，once a week，compared with recombinant human growth hormone (rhGH) in children with idiopathic short stature (ISS). It plans to enroll 300 children with ISS, who will be randomized , stratified by gender and age, and assigned to either the experimental group or the positive controlled group. Each participant will undergo a screening period (up to 12 weeks), a treatment period (52 weeks), and a post-treatment follow-up period (5 weeks). And the safety and efficacy will be evaluated.

This study is a Phase Ia, single-center, randomized, double-blind, dose-escalation, placebo-controlled clinical trial designed to evaluate the safety, tolerability, and pharmacokinetic/pharmacodynamic (PK/PD) profile of ACT100 in healthy participants. A total of 6 dose cohorts are planned, with each cohort enrolling 8 participants (including both male and female participants, where 6 will receive the investigational drug and 2 will receive placebo). The total planned enrollment is 48 healthy participants.

This is a multicenter, randomized, open-label Phase 2 clinical study. It is aimed to enroll 27 essential thrombocytopenia (ET) patients who are resistant to or intolerant of hydroxyurea(HU). Eligible patients will be randomized to receive either Peginterferon α-2b 135 mcg or Peginterferon α-2b 180 mcg at a ratio of 1:2, and all subjects will go through a target treatment period (Weeks 1 \~ Week 48), an extension treatment period (Weeks 49 \~ Week 96) and a follow-up period (Weeks 97 \~ Week 100). Pharmacokinetics, safety, efficacy will be evaluated.
