More Than Half of Bladder Cancer Patients Had No Tumor Left After Pre-Surgery Treatment

Thirty-nine people with muscle-invasive bladder cancer got chemotherapy plus an immunotherapy before surgery to remove their bladder. More than half (56%) had their tumors shrink so much that no muscle-invasive cancer remained. Over one-third had no cancer at all when doctors examined the tissue afterward.

What the trial was testing

The trial enrolled 39 patients with bladder cancer. The study was sponsored by UNC Lineberger Comprehensive Cancer Center and tracked outcomes across the full group of patients who matched the trial's eligibility profile.

It was initial testing (phase 2). Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.

What the results showed

56% of patients had no muscle-invasive cancer left after treatment with chemo plus immunotherapy.

These findings — that had no muscle-invasive cancer remaining after treatment — were published in the Journal of clinical oncology : official journal of the American Society of Clinical Oncology and represent the headline result of the study.

Researchers tracked outcomes across 39 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.

What this means for patients

For patients with bladder cancer, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.

What you can do now

If you have muscle-invasive bladder cancer and are planning surgery to remove your bladder, this combination might shrink or eliminate your tumor beforehand. The treatment uses standard chemo drugs plus an immunotherapy. This was a mid-stage study and the combination is being tested in a larger global trial. Ask your doctor if you might qualify for a clinical trial testing this approach.

Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

A Study to Evaluate the Safety and Efficacy of NDV-01 in Participants With NMIBC

This is a prospective, single-arm study evaluating the safety and efficacy of NDV01 KIT, a fixed-dose combination of gemcitabine HCl and docetaxel, administered via intravesical instillation in patients with high-grade Non-Muscle Invasive Bladder Cancer (NMIBC). NDV01 KIT includes 60 mL Carbopol Gel followed by 15 g NDV01 solution (gemcitabine HCl 1000 mg and docetaxel 40 mg), administered biweekly for six treatments, followed by monthly maintenance therapy for up to 12 months. The study includes a pharmacokinetic (PK) sub-study assessing systemic exposure to NDV01's active ingredients.

IDOV-Immune for Advanced Solid Tumors

This is a Phase I clinical trial evaluating an investigational treatment called IDOV-Immune, a type of oncolytic virus therapy, for adults with advanced solid tumors that have not responded to standard treatments. Oncolytic viruses are designed to infect and destroy cancer cells and have the potential to stimulate the immune system to fight the tumor. The purpose of this study is to determine the safety of IDOV-Immune, how well it is tolerated, and to identify the highest dose that can be safely given. Researchers will also study how the drug behaves in the body, how the immune system responds to it, and whether it shows any signs of shrinking tumors. Participants will receive a single intravenous (IV) infusion of IDOV-Immune and will be closely monitored for side effects and any changes in their cancer. This study is being conducted at multiple sites in the United States and Australia.
