Business Wire
-Zonagen, Inc. (Nasdaq:ZONA) (PCX:ZONA) today announced that the
Company has awarded contracts for its next planned US studies for
both Proellex(TM) and Androxal(TM). Pending review by the FDA this
fall, Zonagen intends to conduct a 150 patient Phase II trial of
Proellex(TM) for the treatment of uterine fibroids and a 210
patient Phase III trial of Androxal(TM) for the treatment of
testosterone deficiency. The Company currently plans on using up to
20 clinical sites for each study. Upon successful completion of
three month preclinical safety studies, Zonagen hopes to submit the
IND for a Phase II trial of Proellex(TM) and the IND update and
Special Protocol Assessment (SPA) for the Androxal(TM) trial over
the next several weeks. Assuming the submissions are acceptable to
the FDA, dosing should commence for both studies before the end of
2005. Pharm-Olam International Ltd ("POI") has been awarded the
contracts for both of the planned studies. POI is a privately
owned, full service, multi-national CRO with corporate headquarters
in Houston, Texas. POI was founded in 1994 and now has clinical
services in over 40 countries including the United States, Eastern
Europe, Western Europe, Russia, South Africa and Latin America. POI
has a proven track record in conducting trials at all stages of the
drug development process, from pre-clinical up to and including
phase IV studies. POI's clients include both large pharmaceutical
companies as well as biotech organizations. Investigators and
patients interested in participating in either of the studies
should contact Dr. Fred Lowrey, Director of Clinical Affairs for
POI. Dr. Lowrey's number at POI is 713-463-8075. The 150 patient
Proellex(TM) study is designed to assess both improvement of
symptoms associated with uterine fibroids as well as effects on the
fibroid itself. The study will test two doses of Proellex(TM)
versus placebo in a double-blind design. The study is of 12 week
duration, and pending outcomes from both six month rodent and nine
month dog studies, results from this Phase II study and subsequent
FDA review, patients may be rolled over into a long term open label
trial in order to assess the continued safety and efficacy of
Proellex(TM). Doses to be used in this trial were previously tested
in a 30 patient, 12-week study of Proellex(TM) in women with
uterine fibroids. That study was conducted in Europe. In the study,
Proellex(TM) exhibited positive effects on fibroid size, bleeding
and pain associated with the condition. The drug was well tolerated
over the course of the study. Proellex(TM) is a once-a-day oral
therapy. The 210 patient Androxal(TM) study is designed to assess
both the improvement in testosterone levels and certain symptoms
associated with low testosterone in men diagnosed with secondary
hypogonadism. The study will test two doses of Androxal(TM) versus
placebo in a double-blind design. The study is of 12 week duration,
and pending outcomes from both six month rodent and nine month dog
studies, results from this Phase III study and subsequent FDA
review, patients may be rolled over into a long term open label
trial in order to assess the continued safety and efficacy of
Androxal(TM). Doses to be used in this trial were previously tested
in a 52 patient, 2-week study of Androxal(TM) in men with secondary
hypogonadism. That study was conducted in the US. In the study,
Androxal(TM) exhibited positive effects on inducing restoration of
normal testicular function as evidenced by achievement of normal
testosterone levels. The drug was well tolerated over the course of
the study. Androxal(TM) is a once-a-day oral therapy. ABOUT ZONAGEN
