Cervical Intraepithelial Neoplasia
August 23, 2010
Advaxis issued positive interim results from a phase II trial of ADXS11-001 for cervical dysplasia. This single blind, placebo controlled, randomized comparison trial plans to enroll 120 female subjects with late stage cervical dysplasia requiring surgical intervention. The subjects received a three dose intravenous regimen of ADXS11-001 using 5x10(7), 3.3x10(8) or 1x10(9) colony forming units at 28 day intervals. At this time the three subjects in the low dose group had received all nine doses. No adverse events associated with the ADXS11-001 administration were observed.

Nventa released positive interim results from a phase I trial of HspE7 for the treatment of cervical intraepithelial neoplasia (CIN). This multi-center, nonrandomized, open-label study enrolled twenty four subjects who were placed in four cohorts. The reported data is from Cohort One, who received subcutaneous doses of 500 mcg of HspE7 and 50 mcg of adjuvant containing Poly-IC, and Cohort Two, who also received 500 mcg of HspE7 and 500 mcg of Poly-IC. The subjects were immunized every twenty-eight days for eight weeks. Four weeks after the last immunization, safety and tolerability as well as T-cell and B-cell specific human papillomavirus (HPV)-E7 immune responses were assessed. The cohort one dose level demonstrated anti-HspE7 antibody responses but limited T-cell responses. In cohort two, three out of four subjects showed anti-HspE7 antibody responses and HPV16 E7-specific T-cell responses. The doses administered in both study cohorts were found to be safe and well tolerated, with no serious adverse events being reported in either group. Based on the results, Nventa plans to commence a phase II study later in 2008.
