Trial Summary

What is the purpose of this trial?

Upon successful screening and registration, enrollment to durvalumab monotherapy (cohort 1) will begin. If DLT criteria outlined in the protocol are exceeded with durvalumab monotherapy (cohort 1), the study will close. Provided the safety of durvalumab monotherapy is established, enrollment to combination regimen cohorts will proceed. Cohorts will simultaneously enroll in parallel to each other with patients assigned to cohorts based on patient slot availability and study site choice of radiation arm participation. Patient assignment to future phase 1 arms would proceed similarly. Within BCG-containing cohorts, treatment will begin at full-dose BCG. If DLT criteria outlined in Section 5.1.4 are exceeded with full-dose BCG, a one level dose reduction of BCG will be implemented. If DLT criteria outlined in Section 5.1.4 are exceeded with reduced-dose BCG, the BCG-containing cohort will not proceed to Phase 2 of the study. Similarly, if DLT criteria outlined in Section 5.1.4 are exceeded within non-BCG containing cohorts, the non-BCG containing cohort will not proceed to phase 2 of the study. Due to the prolonged half-life of antibody therapies, no dose adjustments are planned for durvalumab in any of the cohorts.

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications. However, you cannot use immunosuppressive medication within 14 days before starting the study drug, except for certain exceptions like low-dose steroids or NSAIDs. It's best to discuss your specific medications with the study team.

What data supports the effectiveness of this treatment for bladder cancer?

Research shows that using gemcitabine and docetaxel together can help patients with bladder cancer who did not respond to BCG treatment, providing a durable remission. Additionally, BCG is a standard treatment for bladder cancer, and efforts to enhance its effectiveness with other therapies like immunotherapy are ongoing.12345

Is the combination of immunotherapy and chemotherapy for bladder cancer safe?

Studies have shown that while Bacillus Calmette-Guérin (BCG) is effective for bladder cancer, it can have significant side effects. Alternatives like gemcitabine and docetaxel have been evaluated for safety and are considered tolerable, offering a potential option for those who cannot tolerate BCG.15678

How is the Immunotherapy + Chemotherapy treatment for bladder cancer different from other treatments?

This treatment combines immunotherapy and chemotherapy, using a mix of drugs like Bacillus Calmette-Guérin (BCG), Docetaxel, Durvalumab, Gemcitabine, and Tremelimumab, which is unique because it targets the cancer in multiple ways, potentially offering a more comprehensive approach compared to traditional single-drug therapies.345910

Treatment Details

Interventions

  • Bacillus Calmette-Guérin (BCG)
  • Docetaxel
  • Durvalumab
  • External Beam Radiotherapy (EBRT)
  • Gemcitabine
  • Tremelimumab
Trial OverviewThe trial is testing Durvalumab alone or in combination with treatments like EBRT, Gemcitabine, Docetaxel, Tremelimumab, and BCG for bladder cancer. It starts with Durvalumab; if safe, it adds other treatments. Patients join different groups based on availability and choice of radiation participation.

Experimental Treatment
Group I: Phase 2: Cohort 4 ExpansionExperimental Treatment3 Interventions
Durvalumab + Gemcitabine/Intravesical Docetaxel (Gem/Doc) The sequence of administration is flexible to allow for scheduling of both the infusion and intravesical treatments.
Group II: Phase 1: Cohort 6Experimental Treatment1 Intervention
Additional Regimens (to be determined)
Group III: Phase 1: Cohort 5Experimental Treatment4 Interventions
NOTE: Cohort 5 was abandoned prior to any patients enrolled. Durvalumab + Tremelimumab + Gem/Doc The sequence of administration is flexible to allow for scheduling of both the infusion and intravesical treatments.

Findings from Research

Sequential intravesical gemcitabine/docetaxel (gem/doce) treatment for patients with BCG-unresponsive high-risk nonmuscle invasive bladder cancer showed promising efficacy, with 6-, 12-, and 24-month high-grade recurrence-free survival rates of 78%, 65%, and 49%, respectively, over a median follow-up of 18 months.
The treatment was generally well-tolerated, with mild to moderate adverse effects reported in 57% of patients, and only a small percentage (6.9%) experiencing treatment delays, indicating that gem/doce could be a safe alternative to radical cystectomy for these patients.
Sequential intravesical gemcitabine/docetaxel provides a durable remission in recurrent high-risk NMIBC following BCG therapy.Yim, K., Melnick, K., Mott, SL., et al.[2023]
Bacillus Calmette-Guérin (BCG) is an effective immunotherapy for treating nonmuscle-invasive urothelial carcinoma, but about 30% of patients may still progress to more severe muscle-invasive disease.
Research is ongoing to enhance the immune response against urothelial carcinoma through various innovative therapies, including recombinant BCG, nonlive Mycobacterium agents, and adoptive T-cell therapies, aiming to improve patient outcomes.
Evolving immunotherapy strategies in urothelial cancer.Brancato, SJ., Lewi, K., Agarwal, PK.[2019]
In a study of 35 patients with non-muscle-invasive bladder cancer who experienced BCG treatment failure, sequential intravesical gemcitabine and docetaxel (gem/doce) showed a promising 60% progression-free survival rate at two years, indicating its efficacy as a salvage therapy.
The treatment was generally safe and well-tolerated, with only 37% of patients experiencing adverse events, and a high overall survival rate of 94% at two years, suggesting that gem/doce could be a viable option for patients who are not candidates for radical cystectomy.
