About this study

Official title: SURE-02_An Open Label, Single-arm, Phase 2 Study of Perioperative Pembrolizumab Plus Sacituzumab Govitecan, and Bladder-saving Approach, for Patients With Muscle-invasive Bladder Cancer Who Cannot Receive or Refuse Cisplatin-based Chemotherapy

This is a Phase 2, single-center, open-label, non-randomized study in patients with MIBC who cannot receive or refuse to receive cisplatin-based chemotherapy.

Patients will be consecutively enrolled and treated. All patients enrolled who receive at least 1 cycle of study drug will be included in the primary and secondary endpoint analyses.

Read the detailed description

The general framework of the study will be as follows:

A TURBT for biopsy, histological characterization, and local staging will be executed first, according to the guidelines. With the aim to improve the sensitivity of CT scan in assessing pelvic lymph-nodes and better assess the local extent of bladder tumor, computed tomography (CT) scan, 18FDG-PET/CT scan, and a pelvic MRI will be done during screening and before the surgical assessment to stage and evaluate response. The same imaging assessments will be performed after the neoadjuvant treatment. Patients with the evidence of no detectable disease after neoadjuvant therapy will also undergo a cystoscopy assessment prior to the reTURBT.

  • Eligible patients will receive neoadjuvant treatment: 7.5 mg/kg sacituzumab govitecan IV, on days 1, 8, of each 21 day cycle.
  • Pembrolizumab will be administered in combination with sacituzumab govitecan on day 1, every 21 days, at the standard dose of 200 mg intravenously.
  • A total of 4 cycles is planned before surgery.
  • Patients who achieve a clinical complete response (cCR) will be offered a reTURBT instead of radical cystectomy. Patients not achieving a cCR will undergo a radical cystectomy.
  • cCR will be defined as the achievement of ALL the following requirements: no evidence of residual disease (VIRADS 0 score) at MRI, negative cystoscopy, and a biopsy obtained via reTURBT revealing no residual viable cancer.
  • Surgery will be planned at the time of study inclusion to be done ideally within 4 weeks of the last dose of study drug, and not later than 12 weeks from the last dose of study drug.
  • After surgery patients will receive additional 13 cycles of pembrolizumab at the standard dose, every 3 weeks, accounting for a total of 17 cycles of perioperative pembrolizumab(neoadjuvant + adjuvant).
  • After cystectomy or reTURBT, patients will undergo imagingassessments according to EAU guidelines. In patients undergoing reTURBT, cystoscopy assessments will be performed every 4 months for the first 2 years (until study conclusion),then according to investigator judgment.
  • At the end of the adjuvant period, patients will enter the follow-up period which will lastuntil 12 months from the last dose of pembrolizumab.

What is being measured

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

  1. Clinical CR-rate

    To assess whether sacituzumab govitecan plus pembrolizumab is an effective perioperative strategy in patients with clinical T2-3bN0M0 MIBC who cannot receive or refuse to receive cisplatin-based chemotherapy.

    Measured: 36 months

Secondary outcomes (3)
  1. Pathological response-rate,

    To evaluate the proportion of patients who will be pathological responders.

    Measured: Upon completion of the study up to 40 months

  2. Bladder-intact event-free survival (BI-EFS);

    To evaluate the surgical and medical safety of neoadjuvant combination therapy, as well as of the adjuvant pembrolizumab therapy.

    Measured: Up to 6 months

  3. Overall survival

    To assess survival outcomes (event-free survival and overall survival), in the total population and in the subgroups according to the pathological response.

    Measured: Up to 40 months

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 15 inclusion and 27 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: under way, not looking for participants, as of the sponsor's last update on 2 Apr 2025. 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 Italy. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

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?

Clinical CR-rate (time frame: 36 months). 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 NCT05535218, 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 2 Apr 2025.
