Rövid összefoglaló (regiszter, angolul)

Researchers want to learn if V503 (also called the 9-valent human papillomavirus [9vHPV] vaccine, recombinant) can induce an immune response to HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58 in Chinese females who previously received the bivalent HPV (2vHPV) vaccine. The 9vHPV vaccine protects against diseases caused by 9 types of HPV (6, 11, 16, 18, 31, 33, 45, 52, and 58) and the 2vHPV vaccine protects against diseases caused by 2 types of HPV (16 and 18). The goals of the trial are to learn: * If the 9vHPV vaccine can induce an immune response to HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58 in participants who received the 2vHPV vaccine * About the safety of the 9vHPV vaccine in prior 2vHPV vaccine recipients

Ki nem vehet részt

Szó szerint a(z) ClinicalTrials.gov forrásból, témák szerint csoportosítva. Hogy ki vehet részt, azt csak a vizsgálat csapata dönti el.

Korábbi kezelés

  • Has received, is receiving, or plans to receive the following immunosuppressive therapies: radiation therapy, cyclophosphamide, azathioprine, methotrexate, any chemotherapy, cyclosporin, leflunomide (Arava™), tumor necrosis factor alpha (TNF-α) antagonists, monoclonal antibody therapies (including rituximab [Rituxan™]), intravenous gamma globulin (IVIG), antilymphocyte sera, or other therapy known to interfere with the immune response. With regard to systemic corticosteroids, a participant will be excluded if the participant is currently receiving steroid therapy, has recently (defined as within 2 weeks of enrollment) received such therapy, or has received 2 or more courses of corticosteroids (orally or parenterally) lasting at least 1 week within 12 months prior to enrollment. Participants using inhaled, nasal, or topical corticosteroids are considered eligible for the study.
  • Has received, is receiving, or plans to receive any immune globulin product (including RhoGAM™ [Ortho-Clinical Diagnostics]) or blood derived product other than IVIG.
  • Has participated in an HPV vaccine clinical trial and has received either active agent or placebo.
  • Has received any marketed HPV vaccine other than the 2vHPV vaccines.

Más betegség

  • Has known thrombocytopenia or any coagulation disorder that would contraindicate intramuscular injections.
  • Has a history of abnormal Pap test showing low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL) or atypical squamous cells - undetermined significance (ASC-US), atypical squamous cells - cannot exclude HSIL (ASC-H), atypical glandular cells, or biopsy showing CIN, AIS, or cervical cancer.
  • Has a history of external genital wart, vulvar intraepithelial neoplasia (VIN), vaginal intraepithelial neoplasia (VaIN), AIN, vulvar cancer, vaginal cancer, or anal cancer.
  • Has a history of a positive test for HPV (including HPV types not in the vaccine).
