What is this trial about?

A plain-language summary of the goals, design and what participants do

This clinical trial is focused on studying a type of cancer known as urothelial cancer, which affects the urinary system and can be either locally advanced or metastatic, meaning it has spread to other parts of the body. The study is comparing the effectiveness of a medication called sacituzumab govitecan with other treatments chosen by doctors. Sacituzumab govitecan is a type of medication known as an antibody-drug conjugate, which is designed to target and kill cancer cells.

The purpose of the study is to see how well sacituzumab govitecan works in helping patients live longer compared to other treatments. Participants in the study will receive either sacituzumab govitecan or a treatment selected by their doctor, which could include medications like docetaxel, vinflunine, or paclitaxel. These treatments are given as solutions for infusion, meaning they are administered directly into the bloodstream through a vein.

The study will follow participants over a period of time to monitor their health and the effects of the treatments. The goal is to gather information on how these treatments impact overall survival and other health outcomes in patients with advanced urothelial cancer. This information will help doctors understand which treatments may be most effective for this type of cancer.

The research process

The trial runs in 4 steps – from screening to follow-up. Each step says what happens and what the team monitors.

  1. Step 1

    Joining the study

    Upon joining the study, you will be randomly assigned to one of two groups. One group will receive the medication sacituzumab govitecan, and the other group will receive a treatment chosen by your doctor from a list of options.

  2. Step 2

    Treatment administration

    If you are in the sacituzumab govitecan group, you will receive this medication through an intravenous infusion. This means the medication will be given directly into your vein. The specific dosage and frequency will be determined by your healthcare provider.

    If you are in the group receiving a treatment of your doctor's choice, the options include docetaxel, vinflunine, or paclitaxel. These medications are also administered through intravenous infusion. Your doctor will decide the best option for you, including the dosage and frequency.

  3. Step 3

    Monitoring and follow-up

    Throughout the study, your health will be closely monitored. This includes regular check-ups, blood tests, and other necessary assessments to ensure your safety and to evaluate the effectiveness of the treatment.

    You will be asked to report any side effects or changes in your health to the study team. This information is crucial for assessing the safety and tolerability of the treatments.

  4. Step 4

    End of study participation

    The study is expected to continue until July 31, 2025. Your participation may end earlier if you or your doctor decide it is in your best interest, or if the study team determines it is necessary for your safety.

    At the end of your participation, you will have a final evaluation to assess your health and the outcomes of the treatment you received.

Who can join the trial?

10 criteria

  • Participants must be 18 years or older and able to understand and sign a consent form.
  • Both men and women can participate. Women who can have children and men must agree to use specific birth control methods during the study.
  • Participants must have a type of cancer called urothelial cancer that is either spread to other parts of the body (metastatic) or cannot be removed by surgery (unresectable).
  • Cancer can be in the upper or lower urinary tract. Mixed types of cancer are allowed if the main type is urothelial.
  • Participants must have an ECOG performance status of 0 or 1, which means they are fully active or have some symptoms but do not need bed rest.
  • Participants must have had cancer that got worse or came back after receiving a platinum-containing treatment and a type of therapy called anti-PD-1/PD-L1.
  • Participants with treated brain metastases can join if their brain disease has been stable for at least 4 weeks, they have no new or growing brain tumors, and they are not taking high doses of steroids.
  • Participants must have adequate blood counts without needing blood transfusions or growth factors in the 2 weeks before starting the study drug.
  • Participants must have adequate liver function, meaning certain liver tests are within acceptable limits.
  • Participants must have a creatinine clearance of at least 30 mL/min, which is a measure of kidney function.

Who cannot join the trial?

10 criteria

  • Patients with other types of cancer that are not urothelial cancer cannot participate.
  • Patients who have had a different cancer treatment within the last 4 weeks are not eligible.
  • Patients with severe heart problems cannot join the study.
  • Patients with uncontrolled infections are not allowed to participate.
  • Patients who are pregnant or breastfeeding cannot take part in the study.
  • Patients with a history of severe allergic reactions to similar drugs are excluded.
  • Patients with significant liver or kidney disease cannot participate.
  • Patients who have received a live vaccine within 30 days before the study starts are not eligible.
  • Patients with a history of drug or alcohol abuse that could interfere with the study are excluded.
  • Patients who are unable to follow the study procedures for any reason cannot participate.

Investigated drugs

Sacituzumab Govitecan is a type of medication used in cancer treatment. It is designed to target and attach to specific cancer cells, delivering a powerful drug directly to them. This helps to kill the cancer cells while trying to minimize damage to healthy cells. In this trial, it is being tested to see if it can help people with a type of bladder cancer that has spread or cannot be removed with surgery.

What is already known about the treatment

Sacituzumab Govitecan – Sacituzumab Govitecan is administered as an intravenous infusion, meaning it is given directly into the bloodstream through a vein. It is currently being studied in clinical trials for its effectiveness in treating locally advanced or metastatic urothelial cancer that cannot be surgically removed. This medication works by delivering a toxic substance directly to cancer cells, which helps to kill them while minimizing damage to normal cells. It belongs to a class of drugs known as antibody-drug conjugates, which are designed to target and destroy cancer cells specifically.

Investigated diseases

Locally Advanced or Metastatic Unresectable Urothelial Cancer – This is a type of cancer that originates in the urothelial cells lining the bladder and other parts of the urinary tract. When it is locally advanced, the cancer has spread beyond the bladder to nearby tissues or lymph nodes. In its metastatic form, the cancer has spread to distant parts of the body, such as the liver, lungs, or bones. The term "unresectable" indicates that the cancer cannot be removed completely through surgery. As the disease progresses, it can cause symptoms such as blood in the urine, pain during urination, and frequent urination. Over time, it may lead to more severe symptoms as it affects other organs.
