BOSTON, Nov. 30 /PRNewswire/ -- Surface Logix today announced the
commencement of a company-sponsored Phase IIa clinical trial for SLx-2101, a
new potent and selective long-acting, oral PDE5 inhibitor. SLx-2101 is being
evaluated for the treatment of vascular and cardiovascular disease where
endothelial dysfunction is a significant component of the pathogenesis of the
disease.
This study will assess the safety, tolerability and efficacy of different
single doses of SLx-2101 in patients with erectile dysfunction who are known
to respond to the marketed PDE5 inhibitors. Efficacy will be determined using
the Rigiscan(TM) technique that is well established as a valid measure in
studies of this kind. The study was designed to establish the dose response
and the duration of action of SLx-2101 in patients as suggested by the Phase I
study which demonstrated that SLx-2101 has an extended half-life and
pharmacodynamic activity in healthy subjects.
"This first study in patients will build on the excellent data from the
Phase I study to provide important information about the dose response in
patients. This will direct the design and dosage choices for studies in other
vascular and cardiovascular indications as we continue the clinical
development of SLx-2101. There is significant overlap between the daily doses
of the marketed PDE5 inhibitor for pulmonary hypertension and the dosages used
for erectile dysfunction, supporting our confidence that dosage information
gained from this study with SLx-2101 will help guide our decisions for a range
of Phase IIa and IIb studies," notes Dr. William Prince, Chief Development
Officer of Surface Logix.
"The further progression of SLx-2101 into studies in patients is another
important milestone for Surface Logix. The data from our Phase I study
exceeded our expectations and gave us the confidence to quickly advance SLx-
2101 into a patient population," said Jim Mahoney, Chief Executive Officer of
Surface Logix. "We expect to build a significant body of data for SLx-2101
through the initiation of additional Phase II studies in 2006, and we look
forward to reporting the results of these studies at appropriate scientific
forums next year."
About SLx-2101, Erectile and Endothelial Dysfunction
SLx-2101 is an oral phosphodiesterase-5 (PDE-5) inhibitor designed using
Surface Logix' proprietary small molecule Pharmacomer(TM) Technology. SLx-
2101 is being developed to treat endothelial dysfunction, a physiological
disability of endothelial cells, the cells that line the inner surface of all
blood vessels, arteries and veins, that prevents them from carrying out their
normal biochemical functions. Normal endothelial cells are involved in
mediating the processes of coagulation, platelet adhesion, immune function,
control of volume and electrolyte content of the intravascular and
extravascular spaces. Endothelial dysfunction is believed to be the
underlying cause for several major diseases including atherosclerosis,
congestive heart failure, hypertension and erectile dysfunction.
