Trial summary

Prostate cancer represents the 1st diagnosed cancer in men, with 50400 new cases and 8100 deaths in 2018. Improved diagnostic and therapeutic strategies have led to a 3.7% decrease in mortality between 2010 and 2018 with a 5- and 10-year survival rate of 93% and 80%, respectively.

About this study

Prostate cancer represents the 1st diagnosed cancer in men, with 50400 new cases and 8100 deaths in 2018. Improved diagnostic and therapeutic strategies have led to a 3.7% decrease in mortality between 2010 and 2018 with a 5- and 10-year survival rate of 93% and 80%, respectively.

Pelvic conformal radiotherapy is an important therapeutic technique in the management of pelvic cancers, particularly prostate cancer. However, despite the improvement in radiation techniques, this technique is responsible for acute and late adverse events at the bladder level, these symptoms being grouped under the term radiation cystitis. It has a clear impact on the quality of life of patients. Acute radiation cystitis is likely to occur during treatment or within 3 months after radiotherapy. Its incidence is estimated at nearly 50%. The late form appears on average 2 years after radiation, but can sometimes occur 10 or 20 years later. Its incidence is 5 to 10% of cases.

Although certain factors have been identified, such as the dose received, fractionation or comorbidities, the pathophysiology of radiation-induced cystitis remains unclear, particularly because of the risks of complications arising from access to bladder tissue post-irradiation, thus limiting our knowledge as well as the therapies targeting this process. The use of biomarkers in liquid biopsies allows us to understand the problem of access to irradiated tissues and to highlight protein changes, prognostic of radiation-induced visceral toxicity.

Few works are published on the evaluation of inflammatory and pro-fibrotic biomarkers of radiation-induced cystitis in liquid biopsies. Only 2 retrospective studies have shown a correlation between late radiation cystitis and increased levels of plasminogen activator inhibitor 1 (PAI-1), matrix metalloproteinase inhibitors (TIMP1 and TIMP2), hepatocyte growth factor (HGF), vascular endothelial growth factor (VEGF) and placental growth factor (PIGF) in urine. However, none of these studies explored the variation of biomarkers in the early stage of radiation-induced bladder toxicity.

This would suggest the feasibility of prospective assay of overexpression of these proteins in liquid biopsies.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Biological sample collectionBiological

    The following biological samples will be collected on 4 occasions (at enrollment, 4 weeks after, 12 weeks after and 52 weeks after) :

    • fecal sample
    • urinary sample
    • blood sample (22 ml at each occasion)
  • QuestionnairesOther

    The following questionnaires will be filled by the patients on 4 occasions (at enrollment, 4 weeks after, 12 weeks after and 52 weeks after) :

    • CTCAE Radiation Adverse Event Questionnaire
    • Lower Urinary Tract Disorders Questionnaire (IPSS Score)
    • Quality of Life Questionnaire (FACT-P)
    • Physical Activity Questionnaire (IPAQ)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Concentration of 33 urinary and serum biomarkers potentially related to radiation cystitis between enrollment and 12 weeks after the start of radiotherapy.

    The change in expression of the 33 inflammatory and remodeling biomarkers will be assessed by :

    • the MILLIPLEX® MAP technique for the analysis of circulating markers
    • the flow cytometry method for the analysis of the immune population.

    Measured: Up to to 12 weeks after the start of radiotherapy

Questions about this trial

What is this clinical trial studying?

An observational study of Radiation Cystitis and Prostate Cancer, run by Direction Centrale du Service de Santé des Armées at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 28 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Carole HELISSEY, MD (143985000 ext. +33, carole.helissey@intradef.gouv.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Concentration of 33 urinary and serum biomarkers potentially related to radiation cystitis between enrollment and 12 weeks after the start of radiotherapy. (time frame: Up to to 12 weeks after the start of radiotherapy). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05246774, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Apr 2023.
