General information about the trial
|
|||
Main objective of the trial |
To assess, in a multicentre phase II trial, the safety and efficacy of BEZ235, an oral pan-class I phosphoinositol-3- kinase (PI3K) and mammalian target of rapamycin (mTOR) complex1/2 inhibitor, in locally advanced or metastatic transitional cell carcinoma (TCC) after failure of platinumbased therapy.
|
||
Protection of trial subjects |
All observed or volunteered adverse events regardless of treatment group or suspected causal relationship to the investigational product(s) were reported.
For all adverse events, the investigator must pursue and obtain information adequate both to determine the outcome of the adverse event and to assess whether it meets the criteria for classification as a serious adverse event requiring immediate notification to the study coordinator or its designated representative. For all adverse events, sufficient information should be obtained by the investigator to determine the causality of the adverse event. The investigator is required to assess causality.
|
||
Background therapy |
BEZ235 was administered orally and continuously at a starting dose of 300 mg twice daily. Although it was not a dose‐escalation study, at day 15, based on a clinical evaluation of adverse events, the dose was adjusted for the rest of study. | ||

Recruitment
|
|||||||||||||||
Recruitment details |
Between March 2013 and October 2013, 20 patients from 10 centers including 9 in Belgium and 1 in Luxembourg were included. All patients had locally advanced or metastatic TBI and were previously exposed to platinum-based chemotherapy in the (neo) adjuvant and / or metastatic setting. Out of the 20 patients, only two exhibited PI3K/Akt/mTORpathway. | ||||||||||||||
Pre-assignment
|
|||||||||||||||
Screening details |
Initially, patients were stratified into two groups according to activation of the PI3K / Akt / mTOR pathway (loss of PTEN expression and / or PIK3CA activation vs no loss of PTEN expression and no PIK3CA activation). After Novartis' decision to stop the development of BEZ235, the study design was reviewed and the two groups were merged. | ||||||||||||||

Dosage and administration details |
BEZ235, supplied in sachets of 200 mg, 300 mg and 400 mg. The starting dose is 300 mg PO bid. It is administered orally on the same day on a continuous basis twice a day and should be taken immediately after a meal (e.g. breakfast / dinner), 12 ± 2 hours apart (dinner in the evening), at about the same time every day, except cycle 1, day 1. The full cycle is 28 days. Patients were treated until progression or until criteria for discontinuation were met.

Determine the efficacy of BEZ235 in patients with palliative TCC in term of progression free survival rate (PFSR) at 16 weeks in one group of patients with PI3K/Akt/mTOR pathway deregulations and in one group of patients without PI3K/Akt/mTOR pathway dere [1] | ||||||
End point description |
The PFS rate was defined as the proportion of patients alive and progression-free at 16 weeks. Patients who did not progress were considered as having stable disease, a partial response or a complete response at 16 weeks, according to RECIST 1.1. Patients who were unable to be evaluated at 16 weeks, because of rapid clinical deterioration or death from any cause, or the start of an additional anti-tumour therapy, were considered as having progressive disease.

Notes [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point. Justification: No formal statistical tests were performed on the primary and secondary endpoints. Efficacy analyses were reported overall. The reported results are mainly descriptive (median and range for continuous variables, frequencies and percentages for categorical variables). |

Adverse events information
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Timeframe for reporting adverse events |
All patients will have a follow-up visit scheduled 28 days after the last dose of the study drug to follow for AEs and SAEs that may have occurred after discontinuation from the study.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Adverse event reporting additional description |
For adverse events with a causal relationship to the investigational product, follow-up by the investigator is required until the event or its sequelae resolve or stabilize at a level acceptable to the investigator, and the study coordinator concurs with that assessment.
