Clinical Study on the Safety of CNT-02 for TGCV and NLSD-M

Study Overview
=================
Brief Summary
-----------------
This study is planning to evaluate the safety and clinical efficacy of medium-chain fatty acid capsules (food-grade CNT-02) in subjects with primary triglyceride deposit cardiomyovasculopathy (TGCV) and neutral lipid storage disease with myopathy (NLSD-M) associated with adipose triglyceride lipase (ATGL) genetic defects.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Medium-chain Fatty Acid (CNT-02)<br> | Dietary Supplement: CNT-02<br>* Each subject will take 2.0g of the investigational product orally 3 times a day after every meal.
