Brief Summary
The primary purpose of the clinical study is to evaluate the clinical efficacy of intracranial administration of SB623 cells on patients with chronic motor deficit from Traumatic Brain Injury. A secondary purpose of the study is 1) to evaluate the effect of intracranial administration of SB623 cells on disability parameters and 2) to evaluate the safety and tolerability of intracranial administration of SB623 cells. Patients with stable, chronic motor deficits secondary to focal traumatic brain injury must be 12 months post TBI.

Outcome Measures
Primary Outcomes (1)
Change From Baseline in Fugl-Meyer Motor Scale (FMMS) Score at Week 24 Among All Patients
The FMMS motor component consists of the 33-item upper extremity subscale (UE-FMMS) and the 17-item lower extremity subscale (LE-FMMS). Items were scored on a 3-point ordinal scale: 0= cannot perform; 1= partial motion; 2= full motion Individual items were then summed to determine scores for the 2 subscale scores, as well as a motor total score (total of all item scores including the 2 subscales UE-FMMS and LE-FMMS). As a result, the UE-FMMS subscale score ranged from 0 to 66 and the LE-FMMS subscale score ranged from 0 to 34. The FMMS motor total score ranged from 0 (hemiplegia) to a maximum of 100 points (normal motor performance).

Eligibility Criteria
You may qualify if:
- Documented history of TBI, with correlated MRI or CT
- At least 12 months post-TBI
- Focal cerebral injury able to be identified on MRI (+/- concomitant diffuse axonal injury)
- Neurological motor deficit substantially due to focal cerebral injury observed on MRI
- GOS-E score of 3-6 (i.e. moderate or severe disability)
- Require Motricity Index 10-81 (UE Scale) and/or 10-78 (LE Scale)
- Able and willing to undergo computed tomography (CT) and magnetic resonance imaging (MRI)
- Subjects must be willing to participate in study related exercises to the extent possible
- Able to undergo all planned neurological assessments
You may not qualify if:
- History or presence of any other major neurological disease
- Any seizures in the prior 3 months
- The presence of contracture at any joints that would interfere with interpretation of any of the neurological assessments (e.g. contracture preventing the detection of any increase in the range of motion or ability to perform a task)
- Other neurologic, neuromuscular or orthopedic disease that limits motor function
- Clincially significant finding on MRI of brain not related to TBI
- Known presence of any malignancy except squamous or basal cell carcinoma of the skin
- History of CNS malignancy
- Positive findings on tests for occult malignancy, unless a non-malignant etiology is confirmed
- Uncontrolled systemic illness, including, but not limited to: hypertension (systolic \>150 mm Hg or diastolic \>95 mm Hg); diabetes; renal, hepatic, or cardiac failure
- Uncontrolled major psychiatric illness, including depression symptoms (CESD-R Scale of ≥16)
- Unexplained abnormal preoperative test values (blood tests, electrocardiogram \[ECG\], chest X-ray); x-ray evidence of infection; uncontrolled atrial fibrillation or uncontrolled congestive heart failure
- Presence of craniectomy (without bone flap replacement) or other contraindication to stereotactic surgery
- Participation in any other investigational trial within 4 weeks of initial screening or within 7 weeks of study entry
- Botulinum toxin injection, phenol injection, intrathecal baclofen, or any other interventional treatments for spasticity (except bracing and splinting) 16 weeks priot to the Baseline visit.
- Ongoing use of other non-traditional drugs
