Cellegy Pharmaceuticals To Stop HIV Transmission Study In Ghana

HUNTINGDON VALLEY, Pa., Nov. 8 /PRNewswire-FirstCall/ -- Cellegy Pharmaceuticals, Inc. (Nasdaq: CLGY - News) announced today that the Data Monitoring Committee (DMC) reviewing interim data from the Savvy® Ghana Phase 3 HIV prevention trial made the recommendation that continuing the trial would not allow the effect of Savvy (C31G vaginal gel) on HIV to be determined because of a lower than expected rate of HIV seroconversion in the trial. The estimated annual rate of HIV seroconversion in the Ghana study population was 3.7% at the time of trial initiation, but the observed annual rate was 1.2% eighteen months into the trial, approximately one third of the expected rate. This lower rate was possibly due in part to procedures designed to ensure ethical trial design, including counseling on HIV prevention and distribution of condoms.

Most importantly, the DMC concluded that Savvy appears to be safe and that there is no evidence of safety concerns, based on a review of the comparative numbers of HIV seroconversions in the Savvy and placebo groups, and other interim data.

As a result of the data review, Cellegy, Family Health International (FHI) and the United States Agency for International Development (USAID), which is funding the trial, collectively agreed that the trial in Ghana should be discontinued, and that Savvy should continue to be studied for its effect on preventing HIV transmission. Consideration is being given to expansion of the ongoing Savvy Phase 3 HIV prevention trial in Nigeria and/or the opening of new trial sites in areas with higher HIV incidence as ways to determine the effectiveness of Savvy.

Additionally, data from the Ghana trial will be analyzed for effects on other endpoints including pregnancy. If the data warrant, the Ghana results will be submitted as a supplemental data package for the contraception New Drug Application. Since the analysis of the HIV data did not indicate any safety concerns, the Savvy Phase 3 contraception trial underway in the United States will continue as planned, with enrollment ongoing at sites throughout the U.S. Planning is underway for a second contraception study also at sites in the U.S. Additional studies are planned to examine effectiveness against other sexually transmitted diseases (STDs), including herpes, in the near future.
