About this study

Official title: The Role of Bladder Cancer TAS2R38 Expression on Chemotherapy-Induced Bitter Taste

Alteration in the sense of taste is a frequent symptom that is closely linked to chemotherapy exposure, lowering quality of life and nutritional status. Malnutrition is of particular concern in muscle-invasive bladder cancer (MIBC), as malnutrition is associated with many negative outcomes from radical cystectomy (the surgical procedure in MIBC), which include higher morbidity, poor wound healing, and higher rate of infections after surgery.

It is essential to understand taste changes among participants receiving chemotherapy for MIBC to create future treatment trials.

What participants receive

Study groups in NCT04567719
Study groupRoleWhat they receive
Changes in Taste Perception After Exposure to ChemotherapyA total of 20 participants with histologically-proven MIBC planning to receive pre-surgery chemotherapy followed by radical cystectomy will be recruited.

What is being measured

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

  1. Perceived strength of taste for the bitter and sweet tastes

    Taste solution testing using Spectrum(TM) Descriptive Analysis Method. Taste perception is measured on an ordinal scale (e.g. Moderate, Strong, Very Strong).

    Measured: From baseline (0-14 days prior to initial chemotherapy) until day of surgery (prior to participant undergoing surgery)

Secondary outcomes (6)
  1. Changes in nutrition status

    Patient-Generated Subjective Global Assessment (PG-SGA).The PG-SGA Short Form consist of four questions for the participant to rate their weight, food intake, any symptoms they are experiencing and their activity level, with each answer having a numerical correspondence. That score will be combined with the providers health assessment of weight loss, other health conditions that could affect nutrition, any present symptoms and physical exam; again each evaluation will be given a numeric value. The combined scores will determine the participants level of health; with A being well nourished, B being moderate/ suspected malnourished and C being severely malnourished.

    Measured: 0-14 days prior to initial chemotherapy until (before) day of surgery

  2. Change in body composition

    The Bodystat Quadscan 4000® will measure body fat, lean muscle mass and hydration by placing electrodes on the participants hands and feet. This will show either a resistance or reactance of the electrical flow to determine change in body composition, if any.

    Measured: 0-14 days prior to initial chemotherapy until (before) day of surgery

  3. TAS2R38 expression in tongue and tumor/ tumor- adjacent tissues

    Tongue scraping and tumor tissue will be collected and tested for TAS2R38 in the DNA, RNA and protein.

    Measured: 0-14 days prior to initial chemotherapy until (before) day of surgery

  4. Differences between nutrition status at protocol scheduled visits

    Wilcox signed- rank test will compare each score to determine the changes. The scores will be calculated as either positive or negative numbers. If the total score is positive this will indicate that these measurements are related to taste perception. A negative score will show they are not.

    Measured: 0-14 days prior to initial chemotherapy until (before) day of surgery

  5. Difference between body composition at protocol scheduled visits

    Wilcox signed- rank test will compare each score to determine the changes. The scores will be calculated as either positive or negative numbers. If the total score is positive this will indicate that these measurements are related to taste perception. A negative score will show they are not.

    Measured: 0-14 days prior to initial chemotherapy until (before) day of surgery

  6. Difference between TAS2R38 expression at protocol scheduled visits.

    Wilcox signed- rank test will compare each score to determine the changes. The scores will be calculated as either positive or negative numbers. If the total score is positive this will indicate that these measurements are related to taste perception. A negative score will show they are not.

    Measured: 0-14 days prior to initial chemotherapy until (before) day of surgery

Questions about this trial

What is this clinical trial studying?

An observational study of Bladder Cancer, run by University of Kansas Medical Center at 2 sites in United States.

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 4 inclusion and 5 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 23 Feb 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Perceived strength of taste for the bitter and sweet tastes (time frame: From baseline (0-14 days prior to initial chemotherapy) until day of surgery (prior to participant undergoing surgery)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 23 Feb 2024.
