The Effect of HPV Vaccination on Recurrence Rates in HIV Patients With Condylomata
|HIV Positive Anal Condylomata Anal Warts HIV Infections||Drug: Saline Drug: Quadrivalent Human Papillomavirus (Types 6,11,16,18) Recombinant Vaccine|
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Investigator)
Primary Purpose: Treatment
|Official Title:||The Effect of Human Papillomavirus Vaccination on Recurrence Rates in HIV Positive Patients Treated for Anal Condylomata|
- The Primary Endpoint of This Study is Persistence and Recurrence of Anal Warts as Compared Between the Experimental and Control Groups. [ Time Frame: Follow up evaluation after treatment at 1, 3, 6, 9. 12, 15, 18 months after initial treatment ]Persistence of anal warts will be measured by the presence of any lesions at one month follow-up after surgery. Recurrence of anal warts will be measured by the development of new lesions after one month of follow-up.
|Study Start Date:||July 2007|
|Study Completion Date:||July 2011|
|Primary Completion Date:||July 2011 (Final data collection date for primary outcome measure)|
Placebo Comparator: Placebo
Patients who are in the control group received a placebo of saline in the upper extremity at initial visit, 2 months and 6 months after enrollment.
Active Comparator: Gardasil
The treatment group received a 0.5mL intramuscular injection of Gardasil (quadrivalent HPV vaccine) in their upper extremity at initial visit, and again at two months and six months after enrollment.
Drug: Quadrivalent Human Papillomavirus (Types 6,11,16,18) Recombinant Vaccine
0.5mL intramuscular injection of Gardasil (quadrivalent HPV vaccine) in their upper extremity initially and again at two months and six months after enrollment.
Other Name: GARDASIL
A quadrivalent human papilloma virus (HPV) vaccine called Gardasil had recently (at start of study) been developed and approved by the FDA for the prevention of cervical HPV infection and cervical cancer, which is associated with infection from this virus. It is unknown whether the same vaccine could also be of benefit in treating anogenital warts, which are caused by the same virus. This is an important and clinically relevant question which needs to be answered. Anal warts have a high prevalence and recurrence and usually require extended lengths of treatment and follow-up, especially in the HIV population. At times, treatment of anal warts requires multiple surgeries to excise them if the burden of disease is high. Therefore, this disease represents a significant expense to patients and the health care system.
Further, the HPV virus that causes anal warts has been associated with anal cancer and with its preliminary lesion known as anal intraepithelial neoplasia (AIN). This study touches on two important, relevant and costly healthcare issues: finding a better treatment for the most common sexually transmitted disease in our country, and helping to prevent anal cancer, which is often a fatal disease.
