Trial summary

Although neoadjuvant chemotherapy in muscle-invasive bladder cancer has significantly improved oncological outcomes, approximately 50% of patients do not respond to neoadjuvant chemotherapy, which has adverse effects on patients by causing treatment toxicity and surgical delays.

About this study

Although neoadjuvant chemotherapy in muscle-invasive bladder cancer has significantly improved oncological outcomes, approximately 50% of patients do not respond to neoadjuvant chemotherapy, which has adverse effects on patients by causing treatment toxicity and surgical delays. Therefore, treatment tailored specifically to the individual patient based on the genetic and/or molecular profile of the patient is urgently needed. Among patients scheduled for neoadjuvant chemotherapy, the investigators should differentiate between patients who will be highly effective with neoadjuvant chemotherapy and those who will not, and preferentially select other treatments including radical cystectomy in the patients with high probability of failure to neoadjuvant chemotherapy. However, there is no standard which patients would benefit from neoadjuvant chemotherapy. This study plans to predict treatment response to neoadjuvant chemotherapy in patients with muscle-invasive bladder cancer by analyzing genetic and molecular profiles of tumor tissues obtained through transurethral bladder tumor resection.

Being tested
neoadjuvant chemotherapy followed by radical cystectomy

What participants receive

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

  • neoadjuvant chemotherapy followed by radical cystectomyOther

    combination of dose-dense methotrexate, vinblastine, doxorubicin, and cisplatin (ddMVAC) or combination of gemcitabine and cisplatin (GC) followed by radical cystectomy

What is being measured

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

  1. Identification of responder to neoadjuvant chemotherapy by genetic and molecular profiles

    Evaluation of the treatment response to neoadjuvant chemotherapy of muscle-invasive bladder cancer patients by imaging (CT and/or MRI) using the Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) and correlate with the genetic and molecular profiles of samples (tissue, urine, and blood) analyzed by spatial transcriptomics.

    Measured: At the end of 2 cycles of neoadjuvant chemotherapy (each cycle is 14 days (for ddMVAC) / 28 days (for GC))

Secondary outcomes (4)
  1. overall survival of bladder cancer patients who have undergone neoadjuvant chemotherapy and radical cystectomy

    • Evaluation of the overall survival of bladder cancer patients who have undergone neoadjuvant chemotherapy and radical cystectomy

    Measured: within 10 years after the neoadjuvant chemotherapy and radical cystectomy

  2. cancer-specific survival of bladder cancer patients who have undergone neoadjuvant chemotherapy and radical cystectomy

    • Evaluation of the cancer-specific survival of bladder cancer patients who have undergone neoadjuvant chemotherapy and radical cystectomy

    Measured: within 10 years after the neoadjuvant chemotherapy and radical cystectomy

  3. progression-free survival of bladder cancer patients who have undergone neoadjuvant chemotherapy and radical cystectomy

    • Evaluation of the progression-free survival of bladder cancer patients who have undergone neoadjuvant chemotherapy and radical cystectomy

    Measured: within 10 years after the neoadjuvant chemotherapy and radical cystectomy

  4. recurrence-free survival of bladder cancer patients who have undergone neoadjuvant chemotherapy and radical cystectomy

    • Evaluation of the recurrence-free survival of bladder cancer patients who have undergone neoadjuvant chemotherapy and radical cystectomy

    Measured: within 10 years after the neoadjuvant chemotherapy and radical cystectomy

Questions about this trial

What is this clinical trial studying?

An observational study of Muscle-invasive Bladder Cancer, run by Yonsei University at 1 site in South Korea.

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 2 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: looking for participants now, as of the sponsor's last update on 18 Apr 2024. 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 South Korea. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Won Sik Ham (02-2228-2310, uroham@yuhs.ac), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Identification of responder to neoadjuvant chemotherapy by genetic and molecular profiles (time frame: At the end of 2 cycles of neoadjuvant chemotherapy (each cycle is 14 days (for ddMVAC) / 28 days (for GC))). 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 18 Apr 2024.
