NCT05829629

Brief Summary

BS-02 is a randomised, double-blind, placebo-controlled, phase 1 dose escalation study to assess the safety, tolerability and immunogenicity of FluBHPVE6E7, in women infected with HPV-16. with cervical cytological evaluation negative for intraepithelial lesion or malignancy (NILM), atypical squamous cells of undetermined significance (ASC-US), low grade squamous intraepithelial lesion (LSIL), or low-grade cervical intraepithelial neoplasia (CIN1).

You may qualify if:

  • Females, 18-49 years of age with HPV16 infection and cervical cytological evaluation negative for intraepithelial lesion or malignancy (NILM), atypical squamous cells of undetermined significance (ASC-US), low grade squamous intraepithelial lesion (LSIL), or low-grade cervical intraepithelial neoplasia (CIN1)
  • HPV16 infection has been confirmed at least twice by a validated HPV test separated by at least 3 months
  • Satisfactory colposcopy
  • No clinically significant out of range haematological, renal or hepatic laboratory tests
  • Normal screening ECG or screening ECG with no clinically significant findings, as judged by the investigator
  • Negative serum pregnancy test at screening
  • Agree to use a reliable form of contraception during the whole study period.
  • Provides written informed consent

You may not qualify if:

  • Any vaccination within 6 weeks of day 0
  • Active significant viral infections including influenza, CMV, and EBV within 30 days of receiving study treatment
  • Co-infection with hepatitis B, hepatitis C, or HIV or having other immune deficient states
  • Current Bacterial Vaginosis (BV) infection
  • Current high-grade cervical intraepithelial neoplasia (CIN2/3)
  • Prior history of or current malignancy, vulvar intraepithelial neoplasia (VIN), vaginal intraepithelial neoplasia (VAIN), atypical glandular cells (AGC), adenocarcinoma in situ (AIS) or any suspicion of either micro-invasive or invasive disease
  • Pregnancy, breastfeeding
  • Influenza-like illness (ILI) within 3 months of day 0
  • Known hypersensitivity to oseltamivir or any of its components
  • Any anatomical condition of the cervix, including that resulting from previous cervical surgery, congenital malformation or other condition, that would interfere with a complete evaluation of the cervix
  • Current pelvic inflammatory disease, cervicitis, or other gynaecological infection as per colposcopy and clinical examination
  • Serious, concomitant disorder, including active systemic infection requiring treatment
  • Presence of acute or chronic bleeding or clotting disorder, or use of blood thinners within 2 weeks of day 0
  • A proven or suspected autoimmune disease
  • Immunosuppression including any concurrent condition requiring the continued use of systemic or topical steroids, or the use of immunosuppressive agents, disease modifying doses of anti-rheumatic drugs, and biologic disease modifying drugs. Any immunosuppressive agents containing corticosteroids or monoclonal antibodies specific for the treatment of obstructive airway, ear or vestibular diseases are permissible.
