EVIZON(TM) Phase II Clinical Trial Begins Enrollment Of Patients With Wet Age-Related Macular Degeneration

Genaera
Corporation (Nasdaq: GENR) today announced that the first patient has been
enrolled in a multi-center, open-label, pharmacodynamic Phase II clinical
trial, MSI-1256F-212 (“Study 212”), to explore the efficacy and safety of
EVIZON(TM) (squalamine lactate) at higher doses. Study 212 is designed to
evaluate up to 140 patients with wet age-related macular degeneration
(“AMD”) treated with EVIZON(TM) at four dose levels (40 mg, 80 mg, 120 mg
and 160 mg) over a 20 week period.

“Genaera is pleased to announce the beginning of active enrollment in
Study 212,” commented Jack Armstrong, President and Chief Executive
Officer. “We have assembled an outstanding group of investigators and study
sites and are looking forward to obtaining additional information on the
most effective dose of EVIZON. This study will provide more detailed
information on EVIZON’s effects on visual acuity in both affected eyes of
patients with exudative AMD. There is a significant medical need for a drug
that treats wet AMD in both eyes simultaneously, while avoiding the
complications of intravitreal injections. EVIZON is differentiated from
other competitor drugs having demonstrated a positive effect in both study
and fellow affected eyes in previous clinical trials. We look forward to
confirming that EVIZON is the treatment to meet that medical need.”

For information about participation in EVIZON(TM) clinical trials,
patients and physicians may call Genaera’s Clinical Trial Hotline at (800)
