Finkelstein, president and chief executive officer of RegeneRx.  "We strongly believe in the potential of our drug candidates, which address large, rapidly growing markets and small orphan markets where better products are desperately needed and are diligently moving forward toward the goal of marketing approvals in the U.S. and abroad."
