Clinical Trial Summary

The purpose of this study is to test the safety of gemcitabine applied to the bladder directly combined with different oral doses of everolimus and to assess the right doses. Gemcitabine will be given at a fixed dose. Up to 3 dose levels of everolimus will be evaluated. The purpose of the phase II part is to test the combination of gemcitabine applied to the bladder directly combined with different oral doses of everolimus and to study the effects of these two drugs together. The investigators want to find out what effects, good and/or bad, this treatment has on the patient and the cancer.

• Female patients who are pregnant or breast feeding, Women of childbearing potential (WOCBP) must have a negative serum pregnancy test within 7 days prior to administration of Everolimus.

• Women of child-bearing potential (WOCBP), defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing of study treatment. High effective contraception methods include combination of any two of the following (a+b or a+c or b+c):

• Use of oral, injected or implanted hormonal methods of contraception or;

• Male/female sterilization. Women are considered post-menopausal and not of child-bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks prior to registration. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential.

Intervention

Drug:
• Everolimus and Intravesical Gemcitabine
Phase I: Everolimus will be adm as follows: Dose level 1: 5 mg every other day, Dose level 2: 5 mg daily, Dose level 3: 10 mg daily Phase II: Everolimus will be adm at 10 mg daily the dose determined in Phase I. Pts will receive a dose of 2000 mg of intravesical gemcitabine twice a week (72-96 +8 hours between doses) for 3 weeks for a total of 6 treatments in course 1. After 1 week of rest from intravesical gemcitabine, course 2 will be administered, provided the treating physician notes acceptable pt tolerance. The total number of intravesical instillations will be 12. There will be no dose modifications to gemcitabine; however, pts will be allowed to skip gemcitabine doses if needed, per the treating physician's discretion. Missed or skipped doses of gemcitabine will not be repeated. The pt will receive as many instillations as tolerable up to the maximum of 12 instillations.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Phase I - Dose-limiting Toxicity (DLT)	Everolimus (mg) given in conjunction with intravesical gemcitabine	8 weeks
Primary	Phase II - Patients Who Are Free of Disease at 1 Year	following start of therapy.	1 year
Primary	Phase I - Maximum Tolerated Dose (MTD)	of Everolimus given in conjunction with intravesical gemcitabine	8 weeks
Secondary	Complete Response (CR) Rate	Complete Response (CR) is defined as no evidence of disease (by cytology and cystoscopy). Partial Response is defined as negative cystoscopy and positive cytology. Progression is defined as the development of invasion or metastasis. If the participant develops a recurrence, they will be considered having failed treatment. Participants will also be considered having failed treatment if there is no response to treatment after two cycles.	1 year
Secondary	Survival of Patients Treated	With Everolimus in combination with intravesical gemcitabine. Overall survival following start of therapy will be estimated using Kaplan-Meier methods.	1 year
