Trial Outcomes & Findings for A Study of Rituximab in Combination With Chemotherapy in Relapsed/Refractory Follicular Lymphoma (NCT NCT02472756)

NCT ID: NCT02472756

Last Updated: 2017-08-01

Results Overview

Lymphoma response was assessed using Cheson criteria. Objective response was defined as having either complete remission (CR) or partial remission (PR). Criteria for CR (target lesions): Nodes returned to normal (if greatest transverse diameter \[GTD\] greater than \[\>\] 15 millimeters \[mm\] before therapy, GTD now less than or equal to \[≤\] 15 mm; if GTD 11-15 mm and short axis \[SA\] \>10 mm before therapy, SA now ≤10 mm) and all (non-nodal) target lesions completely resolved. Criteria for CR (non-target lesions): All non-target lymph nodes returned to normal size, all extra-nodal lesions have completely resolved, liver and spleen have returned to normal size (if enlarged at baseline). Criteria for PR: Sum of the product of the diameters (SPD) of target lesions decreased at least 50 percent (%) from baseline and spleen and liver nodules regressed by 50% in SPD or single lesion in GTD.

Follicular Lymphoma Participants
Previously treated adult participants with relapsed/refractory follicular lymphoma received induction treatment with rituximab in combination with chemotherapy regimen for approximately 6 months followed by maintenance therapy with rituximab for a maximum of 2 years. All treatments prescribed during the observation period were at the treating physician's discretion. Participants were followed up for safety and efficacy evaluation in accordance with routine practice, up to 30 months.

PRIMARY outcome

Timeframe: Baseline until disease progression or death, whichever occurred first (up to approximately 6 months)

Population: Intent-to treat (ITT) population. Number of participants analyzed = participants who were evaluable for this outcome.

Lymphoma response was assessed using Cheson criteria. Objective response was defined as having either complete remission (CR) or partial remission (PR). Criteria for CR (target lesions): Nodes returned to normal (if greatest transverse diameter \[GTD\] greater than \[\>\] 15 millimeters \[mm\] before therapy, GTD now less than or equal to \[≤\] 15 mm; if GTD 11-15 mm and short axis \[SA\] \>10 mm before therapy, SA now ≤10 mm) and all (non-nodal) target lesions completely resolved.
