About this study

Official title: A Phase II Trial of Neoadjuvant AGEN1884 Plus AGEN2034 in Combination With Cisplatin-Gemcitabine for Muscle-Invasive Bladder Cancer Prior to Radical Cystectomy

This is a phase II trial to evaluate the tolerability, efficacy, and immune outcomes of AGEN1884 plus AGEN2034 concurrent with cisplatin and gemcitabine in the neoadjuvant treatment of muscle-invasive, non-metastatic bladder cancer prior to radical cystectomy.

Read the detailed description

We will begin with an initial safety run-in to establish the safety of the combination prior to expansion to the full planned phase II. The overall phase II will be an open-label, single arm study in two stages to evaluate the efficacy of the combination in pathologic downstaging of MIBC. Patients will receive four 21-day cycles of neoadjuvant therapy consisting of cisplatin and gemcitabine plus AGEN2034 in all 4 cycles and AGEN1884 in cycles 1 and 3. Patients will proceed to radical cystectomy within 10 weeks after the final dose of this therapy. The primary endpoint of pathologic tumor downstaging will be assessed at the time of cystectomy.

Study groups in NCT04430036
Study groupRoleWhat they receive
Cisplatin, Gemcitabine plus human monoclonal antibodiesExperimentalThe safety run-in of the study will first enroll three patients who will begin treatment with cisplatin and gemcitabine plus AGEN2034 and AGEN1884 as outlined in the treatment plan. These first 3 patients will be assessed for DLTs and there will be a pause in enrollment until all three complete the DLT period. If there are no DLTs in the first 3 patients, we will proceed to further accrual to stage I of phase II. If there is 1 DLT in the initial 3 patients, we will enroll 3 additional patients to the safety run-in. If > 2 DLTs are experienced in the initial 3 patients, the study will be terminated, otherwise additional subjects will be enrolled into the phase ll first stage and reassessed after 2 cycles of therapy and proceed to planned surgery. If criteria are met to continue to the second stage of the Phase II portion of the study, additional patients will be enrolled for an anticipated total of 36 evaluable patients. Patients will be treated and endpoints evaluated.

What is being measured

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

  1. Pathologic Tumor Downstaging of >T2 to pT0

    pT0 or pCR (defined as no residual tumor in bladder and lymph nodes on resected specimen). Surgery should be performed within 6 weeks after completing up to 4 cycles (last dose) of neoadjuvant therapy, but can be done up to 10 weeks after treatment ends to be evaluable. Otherwise this patient must be replaced for response evaluation.

    Measured: Completion of four 21 day cycles (approximately 10 weeks)

Secondary outcomes (4)
  1. Evaluation of Safety and Tolerability of AGEN1884 Plus AGEN2034 Plus Cisplatin and Gemcitabine

    Evaluation of safety and tolerability of using Agen1884 plus AGEN2034 plus cisplating and gemcitabine chemotherapy in the neoadjuvant treatment of muscle-invasive bladder cancer prior to radial cystectomy. Number of adverse events assessed between 3-5 using the National Cancer Institution Common Terminology Criteria for Adverse Events version 5.0 (NCI-CTCAE v5.0)

    Measured: Baseline to 90 days

  2. Pathologic Downstaging to <T2 Rate

    Number of subjects who achieved downstaging of the tumor at completion of the possible 4 chemotherapy cycles.

    Measured: Baseline to Completion of four 21 day cycles (approximately 10 weeks)

  3. Completion of Surgery

    Number of subjects that progressed from therapy to surgery

    Measured: 90 days

  4. Progression-free Survival at 1 Year

    Number of subjects that survived to 1 year from study start without disease progression

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing AGEN1884, AGEN2034 and Cisplatin in people with Urinary Bladder Neoplasms, run by The University of Texas Health Science Center at San Antonio at 1 site 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 19 inclusion and 15 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: stopped early, as of the sponsor's last update on 4 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 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.

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?

Yes. Results are posted in the registry (first posted 4 Apr 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Pathologic Tumor Downstaging of >T2 to pT0 (time frame: Completion of four 21 day cycles (approximately 10 weeks)). 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 4 Apr 2024.
