What side effects are associated with this type of intervention?

Common treatments for bladder cancer, such as PD-L1 inhibitors (e.g., Durvalumab) and BCG therapy, have distinct side effect profiles. PD-L1 inhibitors can cause immune-related adverse events including skin reactions, endocrine disorders, and gastrointestinal issues. BCG therapy often leads to local bladder irritation, urinary symptoms, and occasionally systemic infections. Combining these treatments may heighten the risk of immune-related side effects and local bladder toxicity.

What prior FDA approvals exist?

The FDA has approved several treatments for bladder cancer that are similar to the combination of Durvalumab and BCG. Notably, PD-1/PD-L1 inhibitors such as Pembrolizumab and Atezolizumab have been approved for advanced or metastatic urothelial carcinoma. These drugs work by inhibiting the PD-1/PD-L1 pathway, thereby enhancing the immune system's ability to attack cancer cells. Additionally, Bacillus Calmette-Guérin (BCG) has long been used as an intravesical therapy for non-muscle-invasive bladder cancer, leveraging its immune-stimulating properties to prevent cancer recurrence.

What other types of research exist?

Promising novel alternatives to Durvalumab + BCG for bladder cancer patients include: 1) Pembrolizumab (PD-1 inhibitor) which has shown efficacy in various trials for urothelial carcinoma. 2) Atezolizumab (PD-L1 inhibitor) which has been used in combination with chemotherapy for advanced urothelial carcinoma. 3) Nivolumab (PD-1 inhibitor) either alone or in combination with Ipilimumab (CTLA-4 inhibitor), which has shown benefits in other cancers and is being explored for bladder cancer. 4) Enfortumab Vedotin, an antibody-drug conjugate targeting Nectin-4, which has shown promise in patients who have progressed after PD-1/PD-L1 inhibitors.

PATAPSCO Trial Summary

This trial assesses the safety, tolerability, and efficacy of a new therapy for adults with bladder cancer who have not been treated yet.

Who is the study for?

Adults with high-risk non-muscle-invasive bladder cancer (NMIBC) who haven't had systemic therapy for NMIBC or BCG treatment. Participants must have a life expectancy of at least 12 weeks, good organ and marrow function, and no history of immune-mediated therapy or certain autoimmune disorders. Women can't be pregnant or breastfeeding, and all participants must use effective birth control.Check my eligibility

What is being tested?

The trial is testing the combination of Durvalumab (an immunotherapy drug) with BCG (a type of intravesical therapy) to see if it's safe and works well in treating adults with high-risk NMIBC who are new to this kind of treatment.See study design

What are the potential side effects?

Durvalumab may cause immune-related side effects like inflammation in various organs, skin reactions, hormonal gland problems, infusion-related reactions; while BCG can lead to symptoms such as fever, urinary issues, fatigue and possible risk of infection.

Group I: Durvalumab + BCGExperimental Treatment2 Interventions

Participants will receive Durvalumab for 13 cycles every 4 weeks (q4w) for a maximum 12 months. All participants will receive BCG (supplied by the site) intravesically, as induction weekly for 6 weeks. Patients will subsequently receive BCG for maintenance for 3 weekly doses at 3,6,12,18, and up to 24 months, at the physician's discretion.

Other Research

The most common treatments for bladder cancer, such as Durvalumab and BCG, work by enhancing the body's immune response against cancer cells. Durvalumab, a PD-L1 inhibitor, blocks the interaction between PD-L1 on tumor cells and PD-1 on T-cells, boosting the immune system's ability to attack the cancer. BCG therapy involves instilling a live, attenuated strain of Mycobacterium bovis into the bladder, which stimulates a local immune response targeting the cancer cells. Combining these treatments can enhance both systemic and local immune responses, potentially improving treatment efficacy and reducing tumor recurrence for bladder cancer patients.
