Testing RG1-VLP Vaccine to Prevent HPV-related Cancers

Description

This phase I trial tests the safety, side effects, and best dose of RG1-virus-like particle (VLP) in preventing human papillomavirus (HPV)-related cancers in women. RG1-VLP is a vaccine that aims to protect against rare HPV types not targeted by currently approved HPV vaccines. HPV is a common sexually-transmitted infection that can cause certain genital and oral cancers. RG1-VLP contains a protein of HPV type 16 (HPV16) with a slightly different structure than the licensed Gardasil-9 vaccine. Gardasil-9 is approved by the Federal Drug Administration to help protect against diseases caused by some types of HPV. Gardasil-9 also contains 9 different HPV proteins. Both vaccines contain alum to stimulate the immune system. The usual approach for the prevention of HPV-related cancers for patients who are at increased risk is to consider the currently approved HPV vaccine like Gardasil-9, as well as to be followed closely by their doctor to watch for the development of cancer via routine pap smears. This trial may allow researchers to find out whether the RG1-VLP vaccine can safely trigger an immune response against HPV in healthy women and if it is better or worse than the usual approach for the prevention of HPV-related cancers.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * Women, age 18 - 45 years. Because no dosing or adverse event (AE) data is currently available for the use of RG1-VLP in humans, children and adolescents are excluded from this study
  • * White blood cell (WBC) between 3000/mm\^3 - institutional upper limit of normal
  • * Hemoglobin (Hgb) between 10 g/dl - institutional upper limit of normal
  • * Platelets \>= 100,000/mm\^3
  • * Serum creatinine within institutional normal limits
  • * Bilirubin =\< 2x institutional upper limit of normal
  • * Alanine aminotransferase (ALT) =\< 2x institutional upper limit of normal
  • * Aspartate aminotransferase (AST) =\< 2x institutional upper limit of normal
  • * Human immunodeficiency virus (HIV)-1/HIV-2 negative
  • * Hepatitis B and hepatitis C negative
  • * The effects of RG1-VLP vaccination on the developing human fetus at the proposed doses are unknown. For this reason, all women of childbearing potential will have a pregnancy test and all heterosexually active women must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her study physician immediately
  • * The following persons are not considered to be able to bear children and are therefore eligible to participate without the use of concurrent birth control:
  • * Female with bilateral oophorectomy and/or hysterectomy
  • * Female with fallopian tubes cut, tied or sealed
  • * Female with sterilization implant (e.g. Adiana, Essure) placed \> 3 months prior to randomization
  • * Female post-menopausal (\> 1 year since last menses or prior laboratory follicle stimulating hormone \[FSH\] value per institutional range indicating post-menopausal)
  • * Eastern Cooperative Oncology Group (ECOG) performance status of =\< 1
  • * Ability to understand and the willingness to sign a written informed consent document
  • * History of any of the following:
  • * Prior or current genital warts
  • * For women 25 and older: any abnormal Pap smear and positive HPV deoxyribonucleic acid (DNA) test (if co-testing), or positive HPV DNA test (if primary HPV screening)
  • * Treatment for anogenital intraepithelial neoplasia (cervical intraepithelial neoplasia \[CIN\], anal intraepithelial neoplasia \[AIN\], vaginal intraepithelial neoplasia \[VAIN\], vulvar intraepithelial neoplasia \[VIN\])
  • * Treatment for any cancer
  • * History of anaphylaxis to vaccines or fever \> 100 degrees Fahrenheit (F) within 72 hours of vaccination
  • * Any prior vaccination with Gardasil, Gardasil-9, or Cervarix or other HPV vaccine
  • * Receipt of blood products within 3 months of enrollment, or continuing plasma donation
  • * Participants receiving any other investigational agents
  • * History of allergic reactions attributed to compounds of similar chemical or biologic composition to the adjuvant or to RG1-VLP
  • * Uncontrolled intercurrent illness or psychiatric illness/social situations that would limit compliance with study requirements
  • * Pregnant women or actively lactating women are excluded from this study because RG1-VLP is a vaccine with the potential for teratogenic or abortifacient effects
  • * Planned receipt of any inactivated vaccine in the 2 weeks preceding and the 2 weeks following any trial vaccination
  • * Planned receipt of any live attenuated vaccine in the 4 weeks preceding and the 4 weeks following any trial vaccination
  • * Women with a history of bleeding disorders or use of anticoagulants (aspirin is acceptable)
  • * Had prior medical conditions:
  • * Rheumatoid arthritis or other auto-immune disease
  • * Congenital or acquired immunodeficiency
  • * Collagen vascular disease
