What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 9 participants in total. It began in 2025-07-30 with a primary completion date of 2026-12-31.

Brief Summary

This study aim to investigate the safety and exploratory efficacy of STUP-001 which is AAV-based spinal cord injury investigational product.

Eligibility Criteria

Inclusion Criteria: * Male and female adults aged 19 to 60 years at the time of obtaining informed consent. * Patients diagnosed with traumatic spinal cord injury classified as ASIA Impairment Scale (AIS) grade A or B: 1. AIS-A: Complete loss of sensory and motor function. 2. AIS-B: Partial preservation of sensory function with complete motor paralysis * Patients who have been diagnosed with traumatic spinal cord injury for at least 6 months at the time of screening. At the time of screening, women must provide evidence of non-fertile status by meeting at least one of the following criteria: (a) Postmenopausal women: Defined as women over the age of 50 who have been amenorrheic for at least 12 consecutive months after discontinuing all exogenous hormonal treatments. (b) Women with irreversible surgical infertility, including hysterectomy, bilateral oophorectomy, or bilateral salpingectomy. (Tubal ligation is not accepted.) (c) Women 50 years or younger who have been amenorrheic for at least 12 consecutive months after discontinuing all exogenous hormonal treatments and have luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels within the postmenopausal range defined by the study site. * Acceptable methods of contraception include: 1. Complete abstinence. 2. Tubal sterilization. 3. Hormonal contraceptives with no known drug interactions (e.g., levonorgestrel intrauterine system (IUS) (Mirena), medroxyprogesterone). 4. Copper intrauterine device (IUD). 5. Partner vasectomy. (Note: Periodic abstinence methods (e.g., ovulation timing, symptothermal method, or post-ovulatory methods) and withdrawal are NOT considered acceptable contraception methods.) * Individuals who are able to understand the provided information and can voluntarily sign the written informed consent (or have a legally authorized representative sign on their behalf). Exclusion Criteria: * Patients diagnosed with traumatic spinal cord injury (SCI) classified as AIS-C or D at the time of screening. * Patients with the following cardiovascular conditions at the time of screening: 1. Myocardial infarction or unstable angina within the past 6 months. 2. QTc interval ≥ 450 msec or clinically significant electrocardiographic (ECG) abnormalities. 3. Congestive heart failure (CHF) classified as New York Heart Association (NYHA) Class II or higher. 4. Stroke or transient ischemic attack (TIA) within the past 6 months. * Patients with uncontrolled diabetes mellitus (e.g., HbA1c \> 8% at screening). * Patients with uncontrolled hypertension (e.g., systolic BP \> 180 mmHg or diastolic BP \> 100 mmHg). * Patients diagnosed with, undergoing treatment for, or with a history of malignancy within the past 5 years at the time of screening. * Patients with positive serologic test results for HBsAg, anti-HCV Ab, or anti-HIV Ab at the time of screening. However, patients with positive anti-HCV Ab may be eligible if HCV RNA test results are negative after treatment. * Patients with clinically significant severe infections, as determined by the investigator (e.g., infections requiring continuous concomitant medication for ≥3 weeks during the clinical trial period). * Patients with a history of hypersensitivity to any component of the investigational drug. * Patients with a history of gene or cell therapy involving AAV2. * Patients with the following abnormal laboratory test results at screening: 1. WBC \< 2,000/mm³ 2. Platelet count \< 100,000/mm³ 3. Hemoglobin \< 10.0 g/dL 4. Serum creatinine \> 1.5×ULN 5. Total bilirubin \> 1.5×ULN 6. AST, ALT \> 3×ULN 7. PT-INR/aPTT \> 1.5×ULN * Patients with substance abuse, alcohol dependence, or psychiatric disorders. * Patients who are unable to undergo general anesthesia. * Pregnant or breastfeeding women, or those with a positive pregnancy test at screening. * Patients who have received another investigational drug within 4 weeks prior to screening. However, patients who have not received an investigational drug or participated in non-interventional observational studies may be eligible. * Any other individuals deemed ineligible for the clinical trial at the investigator's discretion.
