Safety and Exploratory Efficacy of Transplantation Therapy Using PSA-NCAM(+) NPC in AIS-A Level of Sub-acute SCI

Recruiting now · Phase 1/Phase 2

Conditions studied: Spinal Cord Injury, Acute, Spinal Cord Injury at C4 Level With Complete Lesion, Spinal Cord Injury at C5-C7 Level With Complete Lesion

In brief

This study intends to evaluate the safety and exploratory efficacy of transplantation therapy using neural precursor cells (PSA-NCAM(+) NPC) derived from the human embryonic stem cell line for the treatment of paralysis and other related symptoms from sub-acute spinal cord injury.

Who can join

Age: 18 and older, up to 65. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Upon written consent of the patient or the legally acceptable representative of the patient
• Male and female patients 18 to 65 years of age
• Female patients who showed negative results on the pregnancy test, use an acceptable contraceptive or have no possibility of pregnancy (at least 2 years have elapsed after menopause or have undergone hysterectomy, ovariectomy, or sterilization operation), or male patients who have received vasectomy or are willing to use contraceptives for up to 90 days after administration of the investigational product using a dual contraceptive method*
• Dual contraceptive method: Method of using multiple contraceptives, such as using a cervical cap or contraceptive diaphragm in addition to a condom for males
• Patients who are capable of being administered with the investigational product on Day 7 to 60 after spinal cord injury
• Patients who have been confirmed to have spinal cord injury classified as AIS-A on ISNCSCI, SCIM and/or MRI by the investigator, physiatrist, or other spinal cord injury specialist
• Patients whose ASIA Impairment Scale (AIS) satisfies AIS-A criteria (spinal segment within C4-C7, complete injury)

You may not qualify if…

• Patients with spinal cord injury caused by penetrating trauma such as gunshot or stab wounds
• Patients with complete transection on the spinal cord
• Patients with spinal cord injury that require more than the mono-segment treatment
• Patients with other complications, including neurological defects related to peripheral nerve injury (neuromuscular injury or central spinal cord syndrome), or etiological causes of paraplegia or sensorimotor defects related to an additional underlying condition
• Patients with multiple lesions or lesions longer than 2 cm in length found on MRI examination
• Patients administered with cells excluding blood transfusion before participating in the clinical study
• Patients with the following intercurrent diseases or conditions:
• Coagulopathy with INR> 1.4 at the time of administration of the investigational product (Day 0)
• Active infection
• Active hypotension requiring vasoconstrictor treatment (less than 60 mmHg of diastolic blood pressure)
• Rupture of the skin on the area of surgery
• Medical history of malignant tumor
• Primary or secondary immunodeficiency
• Clinically significant abnormal values discovered as a result of laboratory tests
• Creatinine > 1.5 mg/dL
• When the level found in the liver-function examination is more than twice the upper limit of the normal level
• Hematocrit/hemoglobin <30%/10 g/dL
• Total WBC < 1000/μL
• Uncontrolled hypertension (systole> 180 mmHg or diastole> 100 mmHg)
• Uncontrolled diabetes (HbA1c> 8%)
• Evidence of GI bleeding on the stool guaiac test
• Positive on tuberculosis test (However, a chest X-ray may be performed if found positive on the TB test, and the patient may be enrolled upon no findings that suggest active tuberculosis on the chest X-ray.)
• Hepatitis B or C
• Human Immunodeficiency Virus (HIV)
• Substance abuse or alcoholism
