1 Exhibit 99.7 CONTACT: Harry W. Wilcox Michelle L. Linn Senior Vice President and CFO Vice President Cambridge NeuroScience, Inc. Feinstein Kean Partners Inc. (617) 225-0600 ext. 119 (617) 577-8110 FOR IMMEDIATE RELEASE CAMBRIDGE NEUROSCIENCE REPORTS PRELIMINARY ANALYSIS OF CERESTAT(1) PHASE III DATA; POTENTIAL BENEFIT IN STROKE SUB-POPULATION TO BE ASSESSED -- COMPANY RESTRUCTURES TO CONSERVE CASH -- CAMBRIDGE, MASSACHUSETTS, MARCH 9, 1998 -- Cambridge NeuroScience, Inc. (Nasdaq: CNSI) today updated its shareholders on the status of its lead product candidate, CERESTAT, for stroke and traumatic brain injury ("TBI"), and on the Company's near-term strategic plan. In September 1997, the Company announced the discontinuation of its Phase III trial in TBI because a planned interim analysis of the data showed insufficient evidence of positive clinical impact. In December 1997, the Company announced the discontinuation of its Phase III trial in stroke after an interim analysis of data from more than 620 patients indicated that continuation of the trial was not justified. At that time, the Company announced its plan to further evaluate the data before making any decisions about the future development of CERESTAT. "Our further analysis has revealed two important initial results," said Elkan R. Gamzu, Ph.D., President and Chief Executive Officer of Cambridge NeuroScience. "First, there were no differences between placebo and CERESTAT on any safety parameter in the TBI trial, which suggests that the drug has an attractive safety profile in this patient population. Moreover, the retrospective stroke trial evaluation had identified a potential therapeutic benefit in a subset of the stroke population which we are continuing to investigate, together with our partner, Boehringer Ingelheim." Dr. Gamzu noted that the Company's near-term strategy now has three components: * First, CNSI and its partner Boehringer Ingelheim are expending additional efforts to further evaluate the stroke findings and to determine if additional clinical studies in the stroke indication will be pursued, either together or by CNSI independently. CNSI is continuing to analyze data on the more than 620 patients enrolled, and anticipates that the final analysis will be available in the second quarter of 1998. At that time, decisions about the future development of CERESTAT in both stroke and TBI indications will be made.

Following such a reduction, the retained staff will be comprised of 11 research scientists in the core technology area of ion-channel blockers, including the collaborative work in ophthalmology with Allergan; 5 scientists in the growth factor area; 4 individuals in clinical development and regulatory affairs; 4 individuals in science support and 6 individuals in administration. The one-time charge related to this reduction in staff will be approximately $800,000. The Company also announced that its Board of Directors had declared on March 9, 1998 a dividend in the amount of $1.00 per share of outstanding Common Stock, payable on April 14, 1998 to shareholders of record on April 2, 1998. Dr. Gamzu said that "while we remain committed to an objective and realistic final analysis of CERESTAT in the near term, our Board of Directors feels it is appropriate to make this extraordinary dividend payment to our shareholders. This dividend is a first step in our program to maximize shareholder value in the short term."
