SECONDARY outcome

Timeframe: Up to 24 months from the start of treatment

Overall survival (OS) rate, measured from the date of starting therapy to the date of death from any cause. Patients alive and patients who are lost to follow up at the time of the final analysis will be censored at the date of the last contact.

SECONDARY outcome

Timeframe: Up to 24 months from the start of treatment

Progression-free survival (PFS) rate: measured from the date of starting therapy to the date of disease progression, relapse or death from any cause. Responding patients and patients who are lost to follow up will be censored at their last assessment date. Patients who will have no tumor assessment after the start of therapy due to interruption of both drugs will be considered failures at the date of treatment interruption in the PFS analysis

Timeframe: Six months from start of treatment

Population: Safety monitoring analysis

In order to monitor the safety of the treatment in small cohorts of patients, the Bayesian approach of Thall, et al. for monitoring toxicity will be used. We have planned the monitoring of toxicity to ensure that the proportion of patients with non-hematological toxicity defined as any non-hematological toxicity of grade 3 or higher after 3 and 6 cycles of induction was not higher than an acceptable level of 25%. The prior probability of toxicity (25%) is modeled by a beta distribution \[Beta (0.5,1.5)\].
