10/5/2012 6:38 AM ET (RTTNews) - Amyotrophic Lateral Sclerosis is a progressive neurodegenerative disease that attacks nerve cells in the brain and spinal cord, leading to complete paralysis, and eventually, death. Also known as Lou Gehrig's disease, Amyotrophic Lateral Sclerosis, or ALS, is said to affect as many as 30,000 Americans, with 5,600 new cases being diagnosed each year.

Currently, there are two FDA-approved drugs to treat ALS namely, Sanofi-Aventis' (SNY:Quote) Riluzole, which prolongs life by 2-3 months, and Avanir Pharmaceuticals Inc.'s (AVNR:Quote) Nuedexta, which treats emotional instability that accompanies this disease.

Developing a neural stem cell therapy for ALS is Rockville, Maryland-based biotechnology company Neuralstem Inc. (CUR:Quote).

For readers who are new to Neuralstem, here's a brief overview of the company's pipeline and the upcoming events to watch out for...

The company is testing its cell product - NSI-566 human spinal cord stem cells, via transplantation technique, in the treatment of ALS symptoms. The phase I NSI-566 study was completed as recently as August of this year. This groundbreaking trial, the first to be approved by the FDA to test neural stem cells in patients with ALS, began in January 2010.

The trial was designed to enroll up to 18 patients, the last of which was treated in August of this year. The entire trial concludes six months after the final surgery.

The interim data on the NSI-566 ALS trial will be updated on October 8, 2012, according to the company.

NSI-566 will also be evaluated in treating motor deficits due to ischemic stroke. The company has received approval to commence a combined phase I/II ischemic stroke trial with NSI-566 in China, and it is expected to begin early next year.

The trial is designed to test up to 118 patients who have suffered an ischemic stroke with chronic residual motor disorder with NSI-566 cell line, 4-24 months post-stroke. The duration of the combined trial, including patient monitoring and data collection, is approximately two years.

Ischemic strokes, the most common type of stroke, occur as a result of an obstruction within a blood vessel supplying blood to the brain. After a stroke, many patients suffer from paralysis in arms and legs, which can be permanent.
