What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a gel spacer made from hyaluronic acid to determine its effectiveness for cervical cancer patients undergoing radiation therapy. The gel, called Barrigel, is placed between the cervix and nearby organs like the rectum and bladder to protect them from radiation and potentially enhance treatment effectiveness. The main goal is to assess the practicality of using this gel and its ability to reduce radiation exposure to healthy organs. This trial targets individuals diagnosed with cervical cancer who are scheduled to receive chemoradiotherapy and brachytherapy (a type of internal radiation). As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this innovative approach.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial team or your doctor.

What prior data suggests that this gel spacer is safe for use in cervical cancer treatment?

Research shows that hyaluronic acid gel spacers, such as Barrigel, are generally well-tolerated. In previous studies with prostate cancer patients, these gel spacers successfully reduced radiation exposure to healthy tissues, protecting sensitive organs like the rectum and bladder during radiation therapy.

Although Barrigel is new to cervical cancer treatment, it has not raised major safety concerns in similar applications. A study on its use in cervical cancer found that serious side effects were rare, with most patients not experiencing life-threatening issues from the gel.

Overall, using a gel spacer like Barrigel is considered safe based on its use in other cancers. It aims to improve treatment while minimizing harm to healthy organs.12345

Why do researchers think this study treatment might be promising?

The treatment using a hyaluronic acid-based gel spacer is unique because it aims to increase the distance between the cervix and the anterior rectal wall during brachytherapy for cervical cancer. Unlike standard treatments like surgery, radiation, and chemotherapy, this gel spacer can potentially reduce radiation exposure to surrounding healthy tissues, minimizing side effects. Researchers are excited about this innovative approach as it could lead to more targeted treatment, enhancing the safety and comfort of patients undergoing chemoradiotherapy.

What evidence suggests that this gel spacer is effective for cervical cancer?

In this trial, participants will receive brachytherapy with a hyaluronic acid-based gel spacer, such as Barrigel, to increase the distance between the cervix and the anterior rectal wall. Research has shown that hyaluronic acid gel spacers reduce radiation exposure to nearby healthy organs. Past studies found that these spacers improve radiation delivery to tumors by creating a gap between the tumor and sensitive organs. This method has been especially successful in treating prostate cancer, where it protects the rectum from radiation. Early results suggest that using gel spacers in cervical cancer can also lower the risk of radiation affecting the bladder and rectum, potentially leading to better tumor control and fewer treatment side effects.14678
