NEURALSTEM PRESENTED CELL THERAPY UPDATE
AT PHACILITATE CELL & GENE THERAPY WORLD CONFERENCE
NSI-566 Trial Data Reveals Biological
Activity Across Multiple Neurodegenerative Diseases: ALS, Chronic Spinal Cord Injury, and Stroke
GERMANTOWN,
MD, January 27, 2016 -- Neuralstem, Inc. (Nasdaq: CUR), a biopharmaceutical company using neural stem cell technology to develop
regenerative therapies and small molecule pharmaceutical drugs for CNS diseases and disorders, announced
that Karl Johe, Ph.D., Neuralstem’s Chairman and Chief Scientific
Officer, provided an update on the company’s ongoing NSI-566 cell therapy clinical programs at the Phacilitate Cell &
Gene Therapy World conference in Washington D.C.
The presentation reviewed the
company’s NSI-566 human spinal cord-derived neural stem cells investigational trials for the treatment of amyotrophic lateral
sclerosis (ALS), chronic spinal cord injury (cSCI), and motor deficits due to ischemic stroke. Dr. Johe highlighted the consistent
biological activity and multiple modes of therapeutic actions, including the rescue of motor neurons, motor improvement, and neuronal
integration in NSI-566 animal and human clinical data. He concluded that the collective trial data analysis showed the cells consistently
demonstrated biological activity in all three indications.
Neuralstem’s NSI-566 cells have been
safely administered to 40 patients, in dosing ranges of 1.2 million to 24 million cells per patient, in four investigational safety
trials. The consistent safety profile continues to validate Neuralstem’s physiologically relevant stem cell technology platform.
The company and its collaborators from leading research institutions conclude that the data supports the advancement of clinical
development in each of the three indications.
“The consistent biological activity
of motor improvement by NSI-566 across multiple disease conditions in humans supports our regenerative hypothesis and is consistent
with our preclinical data,” said Dr. Johe. “Based on these encouraging results, we are preparing to conduct additional
clinical trials in in each of these incurable neurodegenerative indications.”
NSI-566/ALS: A review of the Phase
I and Phase II trials suggested a treatment-emergent improvement of function along multiple endpoints, including improved lung
capacity, muscle strength, and a slowing of ALS progression. Phase I data shows long-term graft survival with transient immunosuppression.
Additionally in Phase II, the data revealed that more than 50% of the patients experienced a reduction in the ALS Functional Rating
Scale (ALSFRS) decline when compared to historical data sets. The remaining subjects, the majority of which had very low grip strength
at entry, did not experience a change in their rate of decline. Based on these observations, the next trial will only include patients
with sufficient muscle strength remaining for potential rescue.
NSI-566/cSCI: The Phase I feasibility
study involved four AIS A thoracic-spinal cord injury patients (motor and sensory complete), one-to-two years post-injury at the
time of stem cell treatment. They each received 1.2 million cells in six injections around the site of the spinal cord injury.
The stem cell treatment demonstrated feasibility and safety; there were no serious adverse events. A self-reported ability to contract
some muscles below the level of injury was confirmed via clinical and electrophysiological follow-up examinations in one of the
four patients treated. There was no change in the clinical status of the three other patients. All patients will be followed for
a total of five years. Dr. Johe commented that the investigators are planning to add a second cohort of four more patients to the
study.
NSI-566/Ischemic Stroke:
Dr. Johe presented encouraging preliminary results from the first cohort of patients in the Phase I NSI-566 feasibility study for
treatment of paralysis from stroke. The Phase I trial is designed to treat three cohorts of three post-stroke patients each, with
Cohort A receiving 5 injections of 40,000 cells each; Cohort B receiving 5 injections of 80,000; and Cohort C receiving 15 injections
of 80,000 cells each. The clinicians have completed dosing the second cohort. Dr. Johe added that an innovative brain injection
cannula, which can safely inject higher doses of cells, was introduced into the study. The trial is being conducted at BaYi Brain
Hospital in Beijing, China.
Dr. Johe’s presentation slides from
the Phacilitate Cell & Gene Therapy World conference are posted on the Investor Center of the Company’s website, www.neuralstem.com.
About Neuralstem
Neuralstem's patented technology enables
the commercial-scale production of multiple types of central nervous system stem cells, which are being developed as potential
therapies for many central nervous system diseases and conditions.
Neuralstem's ability to generate neural
stem cell lines from human hippocampus, which were used for systematic chemical screening for neurogenesis effect, has led to the
discovery and patenting of molecules that Neuralstem believes may stimulate the brain's capacity to generate new neurons, potentially
reversing pathophysiologies associated with certain central nervous system (CNS) conditions.
The company has completed Phase 1a and
1b trials evaluating NSI-189, its first neurogenic small molecule product candidate, for the treatment of major depressive disorder
(MDD), and is expecting to initiate a Phase 2 efficacy study for MDD in 2016.
Neuralstem's first stem cell product candidate,
NSI-566, a spinal cord-derived neural stem cell line, is under development for treatment of amyotrophic lateral sclerosis (ALS).
Neuralstem has completed two clinical studies, in a total of thirty patients, which met primary safety endpoints. In addition to
ALS, NSI-566 is also in a Phase 1 study to treat paralysis due to chronic spinal cord injury, as well as in a Phase 1 study to
treat paralysis from ischemic stroke.
Neuralstem's next generation stem cell
product, NSI-532.IGF, consists of human cortex-derived neural stem cells that have been engineered to secrete human insulin-like
growth factor 1 (IGF-1) protein. The treatment is currently in preclinical investigation for Alzheimer's disease (AD). In animal
study reported at the 2015 Annual Meeting of the American Neurological Association, the cells improved cognition and reduced amyloid
beta (Aβ) plaque load in AD mice.

activities across multiple disease conditions: ALS, stroke, cSCI |
| | Next steps: Pivotal
trials in multiple indications to demonstrate efficacy as the primary objective. |
| | The trials will
be randomized, sham-surgery controlled, double-blinded studies of adequate size to qualify
as registration studies per discussions with the FDA. |
