Brief summary
The purpose of this study is to evaluate the safety and the tolerability of CL2020 cells in hypoxic ischemic encephalopathy neonates with hypothermia therapy. In addition, we will evaluate the efficacy of CL2020 cells for infant development.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of adverse events | until 12 weeks after the administration | Any adverse events are summarized. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Mortality | all of the clinical trial period (up to 44 months) | Mortality is summarized. |
| Overall survival | all of the clinical trial period (up to 44 months) | Overall survival is summarized. |
| Duration of continuous respiratory support | up to 78 weeks | Duration of continuous respiratory support is summarized. |
| Duration of continuous use of vasopressors or pulmonary vasodilators | up to 78 weeks | Duration of continuous use of vasopressors or pulmonary vasodilators is summarized. |
| The composite score of cognitive scale, language scale, motor scale, social-emotional scale, and adaptive behavior scale in Bayley Scales of Infant and Toddler Development Third edition | 78 weeks after administration | Each composite scores are summarized. The higher scores mean a better outcome. |
| Incidence of composite endpoints (death, continuous respiratory support, and continuous use of vasopressors or pulmonary vasodilators) | at 12, 26, 38, 52, and 78 weeks after administration | Incidence of composite endpoints is summarized. |
| Presence of 1) head control, 2) roll over, 3) sitting position, 4) crawl, 5) independent gait, and 6) meaningful words | at 26, 38, 52, and 78weeks after administration | Presence of each event is summarized. |
| Presence of spasticity | at 12, 26, 38, 52, and 78 weeks after administration | Presence of spasticity is summarized. Spasticity is the condition as below: increased muscle tone, or increased deep tendon reflex. |
| Presence of epilepsy | until 78 weeks after administration | Presence of spasticity is summarized. The definition of epilepsy is the condition based on the International League Against Epilepsy. |
| MRI score | at 2, and 78 weeks after administration | MRI score is summarized. The scoring system is based on the report of Barkovich AJ, et al. (AJNR Am J Neuroradiol. 1998 ;19(1):143-9.) . The higher scores mean a worse outcome. |
| Gross Motor Function Classification System (GMFCS) score | at 78 weeks after administration | GMFCS score is summarized. The gross motor function can be categorized into 5 different level. The higher scores mean a worse outcome. |
| The developmental quotient in Kyoto Scale of Psychological Development 2001 | 78 weeks after administration | The developmental quotient is summarized. The higher scores mean a better outcome. |
