Study Comparing Inotuzumab Ozogamicin In Combination With Rituximab Versus Defined Investigator's Choice In Follicular Non-Hodgkin's Lymphoma (NHL)

Registration Number
NCT00562965
Lead Sponsor
Pfizer
Brief Summary

This protocol is designed to assess the efficacy and safety of inotuzumab ozogamicin given with rituximab compared to a defined investigator's choice therapy. Subjects will be randomized to one of these two arms of the study.

Detailed Description

On January 14th 2009, enrollment in the study was discontinued because of poor enrollment and because it was unlikely that the study would meet the estimated enrollment of approximately 978 subjects. The decision was not prompted by the identification of any safety signals in this or other studies. Active treatment and follow-up of the already enrolled subjects was continued. On July, 22th 2010 , the study was amended to shorten the long-term follow-up to one year after active treatment.

Primary Outcome Measures
NameTimeMethod
Progression-Free Survival (PFS)Baseline until disease progression or death or up to 1 year after last dose of study drug

PFS was defined as the time from randomization to disease progression or death due to any cause, whichever occurred first, censored at the last tumor evaluation date. PFS calculated as (Months) = (first event date minus randomization date plus 1) divided by 30.44.

Secondary Outcome Measures
NameTimeMethod
Pharmacokinetics of Inotuzumab Ozogamicin in Combination With Rituximab0, 1, 168 hours on Cycle 1, 2; 0, 1, 2, 168 hours on Cycle 3, 4
Percentage of Participants With Objective Response (OR)Baseline, every 6 to 12 weeks during treatment period, end of treatment (EOT) (42 days after last dose), every 12 weeks during follow-up for up to 1 year after the last dose of study drug

OR was based on assessment of complete response(CR),unconfirmed CR(Cru),partial response(PR) as per International Response Criteria for Non-Hodgkin's Lymphoma.Confirmed response=response persists on repeat imaging at least 4 weeks after initial response.CR=complete disappearance of all detectable clinical/radiographic evidence of disease,lymph nodes regressed to normal size \[at least 1.5 centimeter(cm) or less\],spleen regressed,not palpable on physical examination,bone marrow infiltrate cleared on repeat aspiration/biopsy.PR=at least 50 percent (%) decrease in sum of product diameters of 6 greatest dominant nodes,no increase in other nodes,liver/spleen,no new sites of disease. CRu=residual lymph node greater than 1.5 cm in transverse diameter that has regressed more than 75% in product diameter.Individual nodes previously confluent,regressed more than 75% in product diameters.Indeterminate bone marrow (increased number/size of lymph aggregates without cytologic/architectural atypia).

Overall Survival Probability at Months 6, 12 and 24Baseline up to Month 6, 12, 24

Overall survival was defined as the time from randomization to death due to any cause, censoring at the date of last contact or the end of the study. Participants who withdrew or lost to follow-up from study without having death documented were censored at the date of last contact. Kaplan-Meier estimates of the probability of survival at 6, 12 and 24 months was used to estimate the survival function.
