CHARLOTTE, N.C., July 1, 2013 (GLOBE NEWSWIRE) -- Chelsea Therapeutics International, Ltd. (Nasdaq:CHTP) today announced that it was added to the Russell 3000 ® and Russell 2000 ® Indexes when the Russell Investment Group reconstituted its family of U.S. indexes after stock market close on June 28, 2013. Annual reconstitution of Russell's U.S. indexes captures the 4,000 largest U.S. stocks as of the end of May, ranking them by total market capitalization. Membership in the Russell 3000 ®, which remains in place for one year, means automatic inclusion in the large-cap Russell 1000 ® Index or small-cap Russell 2000 ® Index as well as the appropriate growth and value style indexes. Russell determines membership for its equity indexes primarily by objective, market-capitalization rankings and style attributes. The Russell 3000 ® also serves as the U.S. component to the Russell Global Index, which Russell launched in 2007. Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for both passive and active investment strategies. Approximately $4.1 trillion in assets are benchmarked to the Russell Indexes. Russell calculates more than 700,000 benchmarks daily covering approximately 98 percent of the investable market globally, more than 80 countries and 10,000 securities. These investment tools originated from Russell's multi-manager investment business in the early 1980s when the company saw the need for a more objective, market-driven set of benchmarks in order to evaluate outside investment managers. About Northera NORTHERA™ (droxidopa), the lead investigational agent in Chelsea Therapeutics' pipeline, is currently in Phase III development for the treatment of symptomatic neurogenic orthostatic hypotension (NOH) in patients with primary autonomic failure — an indication that includes a significant number of patients with Parkinson's disease, multiple system atrophy (MSA) and pure autonomic failure (PAF). Droxidopa is a synthetic catecholamine that is directly converted to norepinephrine (NE) via decarboxylation, resulting in increased levels of NE in the nervous system, both centrally and peripherally.
