LIVINGSTON, N.J.--(BUSINESS WIRE)--Columbia Laboratories, Inc. (NASDAQ: CBRX - News) today announced its Phase III clinical trial of progesterone for the prevention of preterm birth in women with a previous preterm birth earlier than 35 weeks gestation did not achieve any reduction in the incidence of preterm birth at week 32, the primary endpoint, or at weeks 28, 35 and 37, secondary endpoints of the study.
Of the 611 evaluable patients in this randomized, placebo-controlled, double blind clinical trial, 302 received placebo and 309 received PROCHIEVE® 8% (progesterone gel). The mean gestational age at delivery was approximately 37 weeks in both the active and placebo groups following treatment, an improvement from a mean of 30 weeks in the previous preterm birth for both groups. Over 60 percent of evaluable patients had a previous preterm birth at or below 32 weeks gestation; prior studies of progestins to prevent preterm birth were comprised mainly of patients with prior preterm births at 34 weeks or greater.
The incidence and profile of adverse events in patients receiving PROCHIEVE 8% was similar to placebo, which was as expected given the product’s documented safety history.
The Company is conducting detailed analyses of the study data, and intends to report the results of this trial in more detail at appropriate scientific venues.
“These study results are extremely disappointing. Despite solid evidence in this and other studies that PROCHIEVE 8% effectively delivers progesterone to the uterus, there was no difference in the reduction of preterm birth incidence in patients with a previous preterm birth earlier than 35 weeks and treated with progesterone versus placebo at any endpoint,” said Robert S. Mills, president and chief executive officer of Columbia Laboratories.
“Although disappointed by these results, we have managed our resources carefully so that Columbia is in a strong position to build our existing infertility business. With our December 2006 acquisition of the U.S. marketing rights to CRINONE® progesterone gel, we are now able to address both of our key infertility audiences, the reproductive endocrinologists and the obstetricians and gynecologists, with the only progestin FDA-approved for use in infertility and for use during the first trimester of pregnancy. We also intend to continue to leverage our bioadhesive drug delivery system for proprietary and third-party opportunities, including our Phase II lidocaine candidate for the prevention and relief of dysmenorrhea,” concluded Mills.
Conference Call
Management will host a conference call to discuss the study results on Monday, February 5, 2007 at 8:30 AM ET at (800) 565-5442 or (913) 312-1298 and online at www.cbrxir.com, under “Events.”
