Clinical Trial Summary

The mTOR (mammalian Target of Rapamycin) protein is the center of the mTOR pathway that plays an important role in cell growth, proliferation, survival and angiogenesis through sensing and integrating energetic signals from cellular environment. The mTOR protein is composed of two complex, mTOR complex 1 (mTOR C1) and mTOR complex 2 (mTOR C2).

In regards of mTOR pathway dysregulations observed in TCC development, there is a rational to test BEZ23 in advanced TCC. BEZ235 is a pan-class I PI3K inhibitor that, in addition, binds to the catalytic site of mTOR, inhibiting mTOR C1 and mTOR C2.

Recruitment information / eligibility

• Status: Terminated
• Enrollment: 22
• Est. completion date: January 2014
• Est. primary completion date: January 2014
• Accepts healthy volunteers: No
• Gender: All
• Age group: 18 Years and older

Eligibility

Inclusion Criteria:

1. Patients with histologically- or cytologically-confirmed locally advanced or metastatic TCC not amenable to curative surgery or radiation.

2. Documented disease progression (according RECIST 1.1 criteria) after first line platinum-based therapy (given in neoadjuvant/adjuvant or palliative setting).

3. An interval of >4 weeks since last anticancer treatment.

4. Archival paraffin-embedded tumor tissue (block or at least 20 unstained slides) of the primary tumor and/or metastases. The most recent archival tissue is mandatory. Recidive of the disease should lead to perform if possible novel biopsies, as major oncogenic differences are found between primary tumor and secondary lesions.

5. At least one measurable lesion by MRI or CT-scan

6. ECOG performance status 0-1, in stable medical condition

7. Patients must have adequate organ function: Hemoglobin = 9 g/100 ml, neutrophils = 1,000/mm3, platelets = 100,000/mm, INR = 1.5, total serum bilirubin = 1.5 x ULN, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) = 3 x ULN (or <5.0 x ULN if hepatic metastases are present), creatinine £1.5 x ULN, fasting plasma glucose <140mg/dl, HbA1c < 8%.

8. Patients must be over 18 years old and able to give written informed consent.

9. Signed informed consent prior to beginning protocol specific procedure

Exclusion Criteria:

1. Non- TCC bladder cancer

2. More than 2 prior chemotherapy regimens given for palliation.

3. Concurrent malignancy or previous malignancy in the last 3 years prior to start the study treatment (with the exception of a history of adequately treated cervical carcinoma in situ or non-melanoma skin cancer)

4. Patient with active uncontrolled or symptomatic central nervous system (CNS metastases).

5. Significant active cardiac disease including uncontrolled high blood pressure, unstable angina, congestive heart failure, myocardial infarction within the previous 6 months, or serious cardiac arrhythmias.

6. Other uncontrolled medical condition (active infections requiring antibiotics, bleeding disorders, uncontrolled diabetes …)

7. Other concomitant anticancer therapy.

8. Previous therapy with PI3K and/or mTOR inhibitors (sirolimus, temsirolimus, everolimus)

9. Concomitant drugs such as coumarin and warfarin, and drugs known to induce torsade de pointe, drugs known to be moderate or strong inhibitors or inducers of CYP3A4

10. Pregnancy or risk of pregnancy.

Intervention

Drug:
• BEZ235
The investigational study drug used in this trial is BEZ235, supplied as 200 mg, 300 mg and 400 mg sachets. BEZ235 is administered continuously twice-daily; complete cycle is 28 days. Starting dose is 300mg PO bid. At cycle 1 day 15, based on a clinical assessment, dose is adjusted for the rest of the study:• If no adverse event (AE) or only mild AE (G1) : the dose will be increase to 400 mg bid• If AE = G2 : the patient will continue at 300 mg bid • If G3 AE or higher : BEZ235 will be interrupt until resolved to = G1 then reduce dose to 200 mg bid
