TP04HN106 in the Treatment of Patients With Amyotrophic Lateral Sclerosis

This trial adopts a multicenter, randomized, double-blind, placebo-controlled parallel design.

This experiment is divided into two groups: the experimental drug group and the placebo group. Successful participants will be randomly assigned to the two groups, with an expected enrollment of 60 participants. There will be 30 participants in the experimental drug group and 30 participants in the placebo group. During the treatment period, the experimental drug group received intravenous injections of 0.83mL/kg TP04HN106 each time; The placebo group received intravenous injections of 0.83mL/kg of saline each time. During the extension period, all subjects received intravenous injection of 0.83mL/kg TP04HN106. In the experiment, all subjects received Liraglutide tablets as the standard baseline treatment.

The subjects who were successfully screened in the experiment were enrolled in sequence, and the safety, tolerability, efficacy, and pharmacokinetic characteristics of the experimental drug were evaluated after administration. The entire trial includes a screening period of 1 week, a treatment period of 12 weeks (including 3 treatment cycles, each treatment cycle of 4 weeks), an extension period of 12 weeks (including 3 treatment cycles, each treatment cycle of 4 weeks), and a follow-up period of 4 weeks. In addition, some subjects underwent a 1-week single dose PK study before the start of the treatment period; In addition, during the first treatment cycle of the treatment period, some subjects were selected for multiple dosing PK studies.

We plan to conduct a single dose PK study among 12 subjects, with 6 subjects in the experimental group and 6 subjects in the control group; Multiple dose PK studies were conducted among 12 subjects, with 6 subjects in the experimental group and 6 sujects in the control group. It is not allowed for the same subject to participate in both single dose and multiple dose PK studies simultaneously.

The 1st to 12th subjects planned to be enrolled in the trial will undergo a single dose PK study. After the first dose, venous blood will be collected from the 12 subjects according to the blood sample collection requirements, and their PK characteristics will be evaluated. The observation period for single dose administration is one week. After completing the final blood sample collection and safety assessment, the subjects enter the treatment period, extension period, and follow-up period.

The 13th to 24th subjects planned to be enrolled in the trial will undergo multiple dose PK studies. These 12 subjects will have their venous blood collected according to the blood sample collection requirements during the first treatment cycle of the treatment period, and their PK characteristics will be evaluated. After completing the treatment period, the subjects will enter the extension period and follow-up period.
