NEW YORK--()--Actinium Pharmaceuticals, Inc. (NYSE MKT:ATNM) ("Actinium" or "the Company"), a biopharmaceutical Company developing innovative targeted payload immunotherapeutics for the treatment of advanced cancers, joined the broad-market Russell 3000® Index as well as the Russell 2000® , Russell Global and Russell Microcap® on June 27, 2014.

"The potential added liquidity from inclusion in Russell Indexes, combined with a stronger balance sheet as a result of our recent offering, places us in a solid position to move aggressively to advance our clinical development programs. We believe we will achieve several value creation milestones over the next twelve months, including the initiation of our Phase 3 trial for Iomab-B and the release of interim data for our ongoing Phase 1/2 trial for our Actimab-A later this year," said Kaushik J. Dave, Ph.D., Actinium’s President and CEO.

Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for active investment strategies. Approximately $5.2 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.
