About this study

Official title: Phase I/II Study of Ipilimumab Plus Nivolumab (IPI-NIVO) Combined With Sacituzumab Govitecan (SG)as First-line Treatment for Cisplatin-ineligible Metastatic Urothelial Carcinoma

The purpose of this study is to see how well the study drugs called Ipilimumab plus Nivolumab (IPI-NIVO) work when added to another study drug called Sacituzumab Govitecan for people who have metastatic bladder cancer.

Read the detailed description

The phase I component of this study will evaluate fixed doses of ipilimumab and nivolumab (3 mg/kg and 1 mg/kg, respectively) IV every 3 weeks x 4 cycles combined with a starting dose of sacituzumab govitecan Level 1 of 8 mg/kg IV days 1,8 every 3 weeks (1 cycle) x 4 cycles. One dose escalation to 10 mg/kg and one dose reduction to dose level minus 1 of sacituzumab govitecan 6 mg/kg days 1,8 every 3 weeks is allowed.

The phase II component will be conducted as two-stage trial enrolling 34 patients with a futility interim analysis after stage 1 (13 patients). After 4 cycles, patients will continue maintenance nivolumab 360 mg IV every Q 21 days along with RP2 dose of SG D1,8 Q21 days till progression of disease or intolerable toxicities or patient decision. Radiographic imaging is performed every 12 weeks to assess response.

What is being measured

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

  1. Phase 1: Maximum Tolerated Dose

    Determine the Maximum Tolerated Dose (MTD)/ Recommended Phase 2 dose (RP2D) of Sacituzumab Govitecan when combined with Ipilimumab and Nivolumab

    Measured: Up to 12 months

  2. Phase 2: Overall Response Rate

    Overall Response Rate (ORR) of Sacituzumab Govitecan with Ipilimumab and Nivolumab combination. ORR is defined as the rate of the best overall response as complete response (CR) or partial response (CR). OR will be summarized by the percentage of responses with a 95% confidence interval as calculated from Clopper-Pearson method.

    Measured: Up to 30 months

Secondary outcomes (6)
  1. Phase 1: Overall Response Rate

    Overall Response Rate is defined as the rate of the best overall response as complete response (CR) or partial response (PR)

    Measured: Up to 12 months

  2. Phase 1: Duration of Response (DOR)

    Duration of Response will be calculated as the date of the first evaluation showing documented response, partial response (PR) or complete response (CR), to the date of the first progressive disease (PD) or death.

    Measured: Up to 12 months

  3. Phase 1: Progression Free Survival (PFS)

    Progression Free Survival defined as the time from start of treatment to the first event of death or progressive disease (PD) per RECIST 1.1.

    Measured: Up to 12 months

  4. Phase 2: Progression Free Survival (PFS)

    Progression Free Survival defined as the time from start of treatment to the first event of death or progressive disease (PD) per RECIST 1.1.

    Measured: Up to 30 months

  5. Phase 2: Duration of Response (DOR)

    Duration of Response will be calculated as the date of the first evaluation showing documented response, partial response (PR) or complete response (CR), to the date of the first progressive disease (PD) or death.

    Measured: Up to 30 months

  6. Phase 2: Overall Survival (OS)

    Overall Survival defined as the length of time from start of treatment until death by any cause. Participants will be evaluated using Kaplan- Meier estimation for survival for up to 6 months after discontinuation of study treatment; patients surviving longer than 6 months will be censored.

    Measured: Up to 30 months

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Ipilimumab, Nivolumab and Sacituzumab govitecan in people with Metastatic Urothelial Carcinoma, run by H. Lee Moffitt Cancer Center and Research Institute 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 9 inclusion and 22 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 17 Dec 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 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Phase 1: Maximum Tolerated Dose (time frame: Up to 12 months). The study lists 2 primary outcomes in all. 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 17 Dec 2025.
