The primary endpoint is the number of Participants with Response according to the criteria of the International Workshop to Standardize Response Criteria for NHL
Complete Remission (CR):
Nodes returned to normal (if GTD >15 mm before therapy, GTD now ≤15 mm; if GTD 11-15 and SA >10 mm before therapy, SA now ≤10 mm) All (non-nodal) target lesions completely resolved
Partial Remission (PR) SPD of target lesions decreased ≥50% from baseline Spleen and liver nodules regress by 50% in SPD or single lesion in GTD
Stable Disease (SD) Not enough shrinkage for PR Not enough growth for PD
Progressive Disease (PD):
SPD increase ≥50% from nadir (smallest value seen during trial) in nodal target lesions overall or in any single nodal target lesion
