ClinConnect Summary

This clinical trial is investigating a new immunotherapy called the PVX7 vaccine for women with advanced cervical cancer who have recently completed their primary treatment. The goal is to see if this vaccine can help boost the body’s immune response against the cancer. The trial is currently not recruiting participants, but it will focus on women aged 18 and older who have no signs of cancer recurrence and have adequate organ function.

To be eligible, participants must meet certain health criteria, such as having healthy blood counts and no active infections. They should also be willing to follow specific care instructions after vaccination, including avoiding close contact with young children and pregnant women for a month. If you or someone you know is considering participation, it's important to discuss any medical history and current health conditions with a healthcare provider to ensure eligibility. This trial could provide valuable information about a potential new treatment option for advanced cervical cancer.

• • Administration of any blood product within 30 days of signing informed consent.
• • Need for ongoing therapeutic anticoagulation during the study period due to concern for increased risk of bleeding.

• • History or presence of atopic dermatitis
• • Inability or unwillingness to for one month post vaccination follow vaccine inoculation site care and avoid social contact with children under 1 year old or close social or domestic contact with a pregnant woman or individuals at high risk of serious adverse effects of vaccinia virus, for instance, those with past or present eczema, or immunodeficiency states including HIV infection
