Phase II Study of HPV Therapeutic Vaccine in HPV Infected Women With Normal Cytology or ASCUS/LSIL
Belgium, Finland239 participantsStarted 2013-12
Plain-language summary
Human Papillomavirus (HPV) 16 and HPV 18 (the two virus genotypes targeted by the ProCervix vaccine) are the most common HPV genotypes associated with at least 70% of squamous cell carcinomas and 82% of adenocarcinomas of the cervix The strategy of therapeutic vaccination with ProCervix is to activate and enhance the patient's cellular immune response to HPV . The therapeutic vaccine will be used for women infected by HPV 16, HPV 18, or both. The vaccine targets these HPV infected women with normal or mild cervical cellular dyskaryosis as detectable infections with oncogenic potential.
This will be a double-blind, randomised, placebo-controlled, parallel group study assessing the efficacy of ProCervix or placebo (concomitantly administered with imiquimod cream).
ProCervix will be delivered with a topical agent, imiquimod, applied to the injection sites as a vaccine adjuvant.
The population proposed for this study represents an otherwise healthy female population who are infected with HPV 16 and/or HPV 18. The safety and tolerability of this therapeutic vaccine has been shown in the ongoing Phase I study, and the proposed population may in theory derive benefit from this vaccine.

What they're measuring
1
Clearance of HPV 16 and HPV 18 infection at Month 12 using a type specific, sensitive and quantitative HPV PCR assay.
. Subject has a current acute or chronic disease, other than infection with HPV, which would be expected to interfere with the planned evaluations of response
ā. Subject has vaginal atrophy with or without topical hormonal therapies or systemic selective estrogen receptor modulators (SERMs).
ā. Subject has prior exposure to HPV prophylactic vaccine or subject has participated in the past in another vaccination clinical trial related to infection with HPV
ā. Current high grade lesions or history of untreated high grade cervical lesion (either CIN2 or CIN3).
ā. Subject has current or a history of cancer of the cervix.
ā. Subject has clinically significant (CS) gynaecological abnormalities that could interfere with study evaluation, in the judgment of the Investigator (e.g. prolapse, myoma, fibroid, hysterectomy).
ā. Subject has a laboratory abnormality Grade ā„ 2, as defined using the Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventative Vaccine Clinical Trials,
ā. Subject has received any live viral vaccine within 3 months or any other non live vaccine within 2 weeks of first study product administration.
