Study of nadofaragene firadenovec alone or with gemcitabine, docetaxel or pembrolizumab in adults with non-muscle invasive bladder cancer who did not respond to BCG therapy

3 1 1 1

What is this study about?

This study focuses on patients with non-muscle invasive bladder cancer who have not responded to previous treatment with Bacillus Calmette-Guerin therapy. The study will evaluate a new treatment approach using nadofaragene firadenovec, either alone or in combination with other medications. The combinations will include chemotherapy drugs (gemcitabine and docetaxel) or immunotherapy (pembrolizumab).

The purpose of this research is to determine how safe and effective these treatment combinations are for patients whose bladder cancer has not responded to standard therapy. The treatment involves placing medication directly into the bladder through a process called intravesical instillation. The study will monitor how well the cancer responds to these treatments over time.

During the study, which may last up to 24 months, participants will receive their assigned treatment according to a specific schedule. Some patients will receive only nadofaragene firadenovec, while others will receive it in combination with either chemotherapy or immunotherapy. The study will track whether the cancer disappears completely after treatment, which is called a complete response.

1 Initial assessment

Your medical condition has been identified as non-muscle invasive bladder cancer that has not responded to previous BCG therapy

Laboratory tests will be performed to check blood counts, liver function, and kidney function to ensure eligibility for treatment

Imaging tests (CT scan or MRI) will be performed to confirm the absence of cancer in the upper urinary tract

2 Treatment assignment

You will be randomly assigned to one of three treatment groups:

Group 1: Nadofaragene firadenovec alone (administered directly into the bladder)

Group 2: Nadofaragene firadenovec combined with chemotherapy (gemcitabine and docetaxel, administered into the bladder)

Group 3: Nadofaragene firadenovec combined with immunotherapy (pembrolizumab, administered through intravenous infusion)

3 Treatment administration

The treatment will be administered according to your assigned group

Regular visits will be scheduled for treatment administration

The medications will be given either directly into your bladder or through an intravenous line, depending on your treatment group

4 Monitoring and follow-up

Regular examinations will be performed to check for any signs of cancer recurrence

Blood tests will be conducted to monitor your overall health

The study will continue until December 2028

You will be monitored for side effects throughout the treatment period

5 Response evaluation

Your response to treatment will be evaluated by checking for the absence of high-grade cancer recurrence

Regular bladder examinations will be performed to assess treatment effectiveness

The main goal is to achieve a complete response, meaning no evidence of high-grade cancer

Trial locations

Nadofaragene firadenovec is a gene therapy medication administered directly into the bladder. It works by delivering genetic material to help fight bladder cancer cells in patients who haven’t responded well to previous BCG therapy.

Gemcitabine is a chemotherapy medication that works by blocking the growth of cancer cells and killing them. It’s commonly used to treat various types of cancer, including bladder cancer.

Docetaxel is a chemotherapy medication that works by stopping cancer cells from dividing and growing. It belongs to a class of drugs called taxanes and is used to treat several types of cancer.

Pembrolizumab is an immunotherapy medication that helps the body’s immune system detect and fight cancer cells. It works by blocking a protein that prevents T cells from attacking cancer cells.

Bacillus Calmette-Guerin (BCG) is a type of immunotherapy made from weakened bacteria. It’s administered directly into the bladder to stimulate the immune system to fight bladder cancer cells. This trial focuses on patients whose cancer didn’t respond adequately to previous BCG treatment.

Non-muscle-invasive bladder cancer (NMIBC) – A type of bladder cancer that affects the inner lining of the bladder without penetrating into the muscle layer. The cancer begins in the cells that line the bladder’s inner surface. It can appear as flat growths (carcinoma in situ/CIS) or as mushroom-like tumors (papillary tumors). The condition can occur in multiple areas of the bladder at the same time. Over time, the cancer cells may continue to grow and multiply within the bladder’s lining.

Carcinoma in situ (CIS) of bladder – A flat, high-grade cancer confined to the innermost layer of the bladder lining. It appears as reddish, velvet-like patches on the bladder’s surface. CIS can be present in one or multiple areas of the bladder. Unlike papillary tumors, these growths remain flat against the bladder wall. The condition is characterized by abnormal cells that have not grown beyond their original location.
