SEOUL, South Korea–(BUSINESS WIRE)–#BrainTransplant—S.BIOMEDICS Co., Ltd. (KOSDAQ: 304360) announced that it has successfully completed the brain transplant of TED-A9 (hESC-derived dopaminergic progenitors) for Phase 1/2a study for treating Parkinson’s disease. The clinical trial was conducted on 12 participants who have been diagnosed with Parkinson’s disease for more than 5 years and exhibited motor complications such as drug wearing-off, freezing of gait or dyskinesia. The participant’s age was between 50 and 75 years old. TED-A9 were administered to 6 participants in the low-dose group (3.15 million cells) and to another 6 participants in the high-dose group (6.30 million cells).
“The first administration began last year and completed the transplantation of 12 patients in February of this year without any special problems,” said Prof. Dong-Wook Kim at Yonsei University College of Medicine, developer of TED-A9 and CTO of S.BIOMEDICS. The primary objective of the Phase 1/2a trial is to assess the safety and exploratory efficacy of TED-A9 transplantation for two years post-transplant. Safety will be monitored for additional 3 years, making it a total 5 years.
An initial cohort of three patients was enrolled at a low dose to assess initial safety, including dose-limiting toxicity (DLT) evaluation, over up to 3 months post-transplantation. There were no safety concerns within this timeframe. Thus, an additional 3 patients were enrolled at a high dose for evaluation over another 3 months post-transplantation. As no safety issues arose during this extended period, the clinical trial continued by adding three further patients to each of the low-dose and high-dose groups, totaling 12 patients. “The transplantation process targeted three segments of the putamen; the anterior, middle, and posterior sections, with three tracks per each putamen. Bilateral putamina received cell transplantation in a single surgical procedure, with cells injected at three points within each track,” Prof. Dong-Wook Kim explained.
The clinical trial was conducted at Severance Hospital led by Prof. Jin-Woo Chang, a neurosurgeon and the principal investigator of the transplant and Prof. Phil-Hyu Lee, a neurologist. According to Prof. Chang, none of the 12 Parkinson’s disease participants had any side effects, complications, or unusual adverse reactions following the transplantation of TED-A9.
The development of TED-A9 has been led by Prof. Dong-Wook Kim. TED-A9 is ventral midbrain-specific dopaminergic progenitors derived from hESCs by exclusively utilizing small molecules. TED-A9 represents a significant advancement in the field, offering highly purified dopamine cells derived from hESCs. S.BIOMEDICS believes that when surgically transplanted into the brain, these high-purity dopamine cells, replacing dead cells, have the potential to restore the motor function of patients with Parkinson’s disease.
“At S.BIOMEDICS, we are committed to developing data-driven medicine for Parkinson’s disease,” said Prof. Dong-Wook Kim. “We have developed a fundamental therapeutic mechanism that directly replaces dopaminergic neurons lost in patients with Parkinson’s disease. TED-A9 could represent a fundamental treatment that surpasses current therapies, which only temporarily alleviate the symptoms of Parkinson’s disease,” he added.
