Summary

eRapa (encapsulated rapamycin) will be investigated for secondary prevention in patients with diagnosed non-muscle invasive bladder cancer (NMIBC) through a phase II double-blind randomized controlled trial of long-term (one year) prevention with eRapa versus placebo. The primary hypothesis is that eRapa decreases the risk of cancer relapse for patients with NMIBC. Secondary hypotheses are that eRapa can improve certain immune parameters and improve cognition and physical function without adversely affecting patient-reported outcomes and quality of life.

Description

The study is a multi-site phase II double-blind randomized trial. Subjects will be randomized into placebo arm or intervention arm with low dose (0.5 mg) eRapa (encapsulated rapamycin) Monday-Friday for one year or until disease recurrence. Patients will undergo endoscopic evaluation of the bladder every 3 months for 2 years, then every 6 months for 2 years, and at year 5. Some patients may also concurrently receive BCG immune therapy maintenance (weekly for 6 weeks for induction period, weekly for 3 weeks at 3 months, 6 months, and then every 6 months for a total of 7 maintenance cycles following tumor removal) per standard of care. Patient-reported outcome (PRO) assessments, cognitive assessments, and physical assessments will be completed according to the study calendar. Research blood to assess safety, immune response and rapamycin level will be collected regularly throughout the study period. Participants will be followed for up to 5 years following enrollment.

Eligibility

 Yes No Not Sure

Inclusion Criteria

Pathologically (histologically) proven diagnosis of non-muscle invasive (Ta, Tis, or T1) bladder cancer within 90 days prior to enrollment
Able to give informed consent
years or older
Patients must not be taking oral glucocorticoids at the time of registration
Not have active, uncontrolled infections
No other prior non-bladder malignancy is allowed except for the following: adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, adequately treated Stage I or II cancer from which the patient is currently in complete remission, or any other cancer from which the patient has been disease free for five years
Patients with localized prostate cancer who are being followed by an active survelillance program are also eligible
Patients must not be pregnant or nursing, as the use of Intravesical BCG is not recommended during pregnancy. Women/ men of reproductive potential must have agreed to use an effective contraceptive method. A woman is considered to be of "reproductive potential" if she has had menses at any time in the preceding 12 consecutive months. Examples of effective contraception include hormonal contraception, double barrier method (condom with spermicidal cream, diaphragms with spermicidal cream, or condoms with diaphragms), Intrauterine device, and/or partner vasectomy. In addition to routine contraceptive methods, "effective contraception" also includes heterosexual celibacy and surgery intended to prevent pregnancy (or with a side-effect of pregnancy prevention) defined as a hysterectomy, bilateral oophorectomy, or bilateral tubal ligation. However, if at any point a previously celibate patient chooses to become heterosexually active during the time period for use of contraceptive measures outlined in the protocol, he/she is responsible for beginning contraceptive measures. Both male and female patients will be required to disclose contraception method during screening and agree to continue to use that contraception method through the end of their participation in the study
Patients must have had all grossly visible papillary tumors removed within 90 days prior to registration or cystoscopy confirming no grossly visible papillary tumors within 90 days prior to registration
Patients with T1 disease must have cross-sectional imaging of abdomen/pelvis demonstrating no evidence of nodal involvement or metastatic disease (MRI or CT scan) within 90 days prior to registration. Patients with T1 disease must have re-resection confirming ≤ T1 disease within 90 days prior to registration
Patients must no have received prior intravesical BCG

Exclusion Criteria

Have muscle-invasive or higher (≥T2) bladder cancer
Unable to give informed consent
Age 17 or younger
Taking oral glucocorticoids at the time of registration
Another cancer requiring active treatment (except basal cell carcinoma or squamous cell carcinoma of the skin)
Patients at risk of pregnancy that are unwilling or unable to take effective contraception during the study period, or patients that are nursing during the study period. Women/ Men of reproductive potential must have agreed to use an effective contraceptive method or will be considered ineligible for study participation
Evidence of nodal involvement or metastatic disease (MRI or CT scan) within 90 days prior to registration
History of prior intravesical BCG
History of prior Rapamycin treatment
