SGN-00101 Vaccine in Treating Human Papillomavirus in Patients Who Have Abnormal Cervical Cells

Summary
Brief summary (as posted)
This randomized phase II trial is studying how well SGN-00101 vaccine works compared to a placebo in treating human papillomavirus and preventing cervical cancer in patients with abnormal cervical cells. Vaccines, such as SGN-00101, may make the body build an immune response to kill human papillomavirus and abnormal cervical cells and may be effective in preventing cervical cancer
