Patients with other neuromuscular diseases or neuropathy-inducing factors: Patients with chronic alcohol addiction, undergoing anticancer chemotherapy, or taking neurotoxic drugs
Patients diagnosed with diabetes
Patients diagnosed with inflammatory bowel disease
Patients with a history of stroke or cerebral ischemic attack within 12 months prior to the screening date
Patients with a history of coronary artery disease, such as myocardial infarction and unstable angina pectoris, within 12 months prior to the screening date
Morbidly obese patients with body mass index (BMI) ≥ 37
Patients who underwent orthopedic surgery (corrective surgery for bone and ligament, artificial joint implantation, osteosynthesis, osteotomy, arthroscopic surgery) in the lower limbs within 6 months prior to the screening date
Patients who may be affected by the muscle strength measurement test due to ankle contracture or surgery
Patients with uncontrolled hypertension (if systolic blood pressure is ≥ 160 mmHg or diastolic blood pressure is ≥ 100 mmHg at screening)
Patients or patient's immediate family members (parents, siblings, offspring) with a history of malignant tumors within the last 5 years prior to the screening date, excluding basal cell carcinoma or squamous cell carcinoma that occurs on the skin (if it is determined that there is no possibility of relapse after resection), or with a family history of familial adenomatous polyposis (FAP) or hereditary nonpolyposis colorectal cancer (HNPCC)

Patients who have not completed a national cancer screening program applicable to their sex and age (if it cannot be confirmed that the relevant test was received at a national cancer screening center or a recognized screening center)

However, if it is confirmed that the relevant test was received at a national cancer screening center or a recognized screening center during the screening period, and that the results were within normal range, the patients may participate in the clinical study.

Common to males and females: If a patient is ≥ 50 years of age, the results of a colonoscopy within 5 years prior to the screening must be determined as being within normal range, and if adenomatous polyps are evident, the results of a colonoscopy within 1 year must be determined as being within normal range (inflammatory polyps or hyperplastic polyps are included in the normal range). If a patient is ≥ 40 years of age, the results of a gastroscopy within 2 years prior to the screening must be within normal range. If a patient is ≥ 54 years of age and has a 30 pack-year history of smoking or more, the results of a low-dose chest CT within 2 years prior to the screening must be within normal range. In case of liver cancer, carriers of hepatitis B or hepatitis C virus and patients with hepatic cirrhosis fall under the exclusion criteria.

Females: For females ≥ 40 years of age, normal range findings must be confirmed in a mammogram within 2 years. For females ≥ 20 years of age, normal range findings must be confirmed in a Pap smear within 2 years.

Individuals who participated in another clinical study within 6 months before the time of screening
Individuals who have shown significant adverse events such as hypersensitivity reactions to the investigational product
Pregnant or breastfeeding females
Other individuals determined ineligible by the principal investigator to participate in the clinical study due to other reasons including clinical laboratory test results
