Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is looking at the effects of Sirolimus (Rapamycin) on BCG-specific immunity during treatment of non-muscle invasive bladder cancer (NMIBC) with maintenance BCG.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study will evaluate change from baseline in gamma-delta T cell numbers and function and Ag85 peptide-specific T cell responses following treatment.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Pathologically (histologically) proven diagnosis of non-muscle invasive (Ta, Tis or T1) bladder cancer
* In their treating physician's opinion is a good candidate for BCG therapy
* Be able to give informed consent
* Be age 18 or older
* Not be in an immunosuppressed state (e.g. HIV, use of chronic steroids)
* Not have active, uncontrolled infections
* Not be on agents known to alter rapamycin metabolism significantly
* Not have a reported history of liver disease (e.g. cirrhosis)
* Not have a prior history of non-bladder cancer unless the cancer is clinically stable and not requiring active treatment except basal cell carcinoma or squamous cell carcinoma of the skin.
* Not pregnant, or taking effective contraception before rapamycin therapy, during therapy and for 12 weeks after discontinuation of therapy.

Exclusion Criteria

* Have muscle-invasive (≥T2) bladder cancer
* Unable to give informed consent
* Age \< 18
* Immunosuppressed state (e.g. HIV, use of chronic steroids)
* Active, uncontrolled infections
* On agents known to alter rapamycin metabolism significantly
* Another cancer requiring active treatment (except basal cell carcinoma or squamous cell carcinoma of the skin)
* Patients at risk of pregnancy who are unwilling or unable to take effective contraception before rapamycin therapy, during therapy, and for 12 weeks after discontinuation of therapy.
* Individuals with a reported history of liver disease (e.g. cirrhosis)
* Individuals who are not a good candidate for BCG in their treating physician's opinion
