COR Cortex Pharmaceuticals,

Cortex Pharmaceuticals, Inc. (NYSE Amex: COR) reported a net loss of $3,168,000, or $0.07 per share for the quarter ended March 31, 2009 compared with a net loss of $4,371,000, or $0.09 per share for the corresponding prior year period.

The loss for the 2009 quarterly period included one-time charges for the reduction in force that occurred in mid-March. Non-cash stock-based compensation charges included in net losses for both periods amounted to approximately $153,000 and $408,000 for the quarters ended March 31, 2009 and 2008, respectively.

Operating results also reflect preclinical development expenses incurred in the prior year period for AMPAKINE� CX1739. During the quarter ended March 31, 2009, Cortex completed Phase I clinical testing of the compound in the U.K. CX1739 was well tolerated and exhibited linear exposure with increasing doses. Cortex has subsequently initiated a small, proof-of-concept clinical study with CX1739 in the U.K. in patients with moderate-to-severe sleep apnea and anticipates receiving related top-line results around mid-2009.

During 2008, Cortex announced results from two pilot studies completed with an oral formulation of AMPAKINE CX717, which demonstrated that CX717 prevented the onset of respiratory depression in humans without interfering with the pain-relieving properties of the opiate.

As stated above, during the quarter ended March 31, 2009, Cortex implemented a reduction of approximately 50% of its personnel. At the same time, the company decreased the salaries for its executive officers. As a result of these actions, Cortex decreased its spending requirements to better align its resources with its clinical development programs for i.v. CX717 and oral CX1739.

Shortly after the reported period, in April 2009, Cortex completed a registered direct offering to a single investor for gross proceeds of approximately $1,500,000. Net proceeds from the offering were approximately $1,250,000.

Cortex continues its on-going discussions related to other strategic alternatives, including licensing, partnering and M&A opportunities. There can be no assurance that a transaction will be finalized from these discussions.

Cortex Pharmaceuticals, Inc.

Cortex, located in Irvine, California, is a neuroscience company focused on novel drug therapies for treating psychiatric disorders, neurological diseases and brain-mediated breathing disorders. Cortex is pioneering a class of proprietary pharmaceuticals called AMPAKINE� compounds, which act to increase the strength of signals at connections between brain cells. The loss of these connections is thought to be responsible for memory and behavior problems in Alzheimer�s disease. Many psychiatric diseases, including schizophrenia, occur as a result of imbalances in the brain�s neurotransmitter system. These imbalances may be improved by using the AMPAKINE technology.
