Vaccines made from antigens may make the body build an immune response to kill abnormal
cervical cells and may be effective in preventing cervical cancer. Randomized phase II trial
to study the effectiveness of vaccine therapy in preventing cervical cancer in patients who
have cervical intraepithelial neoplasia
I. Determine the efficacy of SGN-00101, in terms of complete histologic regression, in
patients with grade III cervical intraepithelial neoplasia.
II. Determine the toxicity of this drug in these patients.
I. Determine change in lesion size in these patients after treatment with this drug.
II. Compare histologic response before and after treatment with this drug in these patients.
OUTLINE: This is a randomized, multicenter study. Patients are randomized to 1 of 2
Arm I: Patients receive SGN-00101 subcutaneously once on weeks 1, 4, and 8 in the absence of
Arm II: Patients receive standard care.
At week 15, all patients undergo large loop excision of the transformation zone under
Patients are followed at 19 weeks, every 3 months for 1 year, every 6 months for 2 years,
and then annually thereafter.
PROJECTED ACCRUAL: A total of 28-84 patients (14-42 per treatment arm) will be accrued for
this study within 12-48 months.
