Taltirelin Hydrate, an active substance of C-Trelin OD tablet 5mg, is an analogue of Thyrotropin Releasing Hormone(TRH). TRH is distributed widely in the brain, and exerts variety of central nervous system effects as well as endocrine activity such as releasing of Thyroid Stimulating Hormone(TSH) and Prolactin. Based on these actions, studies have been attempted for the treatment of various neurological diseases such as refractory epilepsy, cerebellar ataxia, amyotrophic lateral sclerosis, cerebellar ataxia and so on. C-Trelin OD tablet 5mg (Taltirelin Hydrate) for the clinical trial is a commercially available drug that was approved by Ministry of Food and Drug Safety(MFDS) based on the safety and efficacy. However, the studies with this medicine were conducted before 1997, and the evaluation criteria for the efficacy was quite different from the current evaluation criteria.~In this clinical trial, K-SARA as an objective evaluation criteria validated in Korean patients is used to confirm the efficacy of C-Trelin to improve ataxia, and to prove safety by evaluating changes in clinical laboratory data and adverse events.
The aim of this study is to evaluate the efficacy and safety of C-Trelin OD Tablet 5mg(Taltirelin Hydrate) in randomized, double-blind, placebo-controlled clinical trial in patients with ataxia induced by spinocerebellar degeneration.
