Clinical Trial Summary

This study treats patients with diffuse large B-cell lymphoma whose disease is in complete remission due to previous treatment with Cyclophosphamide Doxorubicin hydrochloride Vincristine Prednisolone- Rituximab (CHOP-R). Half of the patients received Zevalin and the other half receive no further anti-cancer treatment. The two patient groups compared to determine if Zevalin given after CHOP-R therapy provides greater benefits than receiving no additional anti-cancer therapy after CHOP-R.

Description:

The objectives of this study were to evaluate the efficacy and safety of the Zevalin study regimen compared with observation alone in patients with complete remission (CR or CRu) after first-line CHOP-R, the study was to include patients 60-years-of-age or older with histologically confirmed Ann Arbor stage II, III, or IV diffuse large B-cell lymphoma End Points: Primary endpoint: Overall survival (OS) Secondary endpoints: Disease-free survival (DFS), health-related quality of life (HRQL) as assessed by the patient using standard questionnaires . Number of Patients : A total of 400 patients (200 per arm) were planned to be enrolled. - In fact, 68 randomized patients (full analysis set; FAS) were analysed; 34 patients per each arm. The per-protocol set (PPS; 65 patients) comprised 33 patients allocated to the Zevalin arm and 32 patients allocated to the observation control arm. Study Treatment : The combination regimen with rituximab was designed in 2 steps as follows: - Day 1: Initial administration of 250 mg/m^2 rituximab, followed immediately by administration of 185 megabecquerel (MBq) (5 millicurie [mCi]) of [111In]-ibritumomab tiuxetan (the latter one only in centers where biodistribution imaging or dosimetry was compulsory according to local law). In centers where biodistribution imaging or dosimetry had not been required, the first rituximab infusion was given alone. - Day 7-9: Rituximab 250 mg/m^2, followed immediately by [90Y]-ibritumomab tiuxetan 14.8 megabecquerel/kilograms (MBq/kg) (0.4 millicurie / kilogram [mCi/kg]) (maximum dose 1184 MBq) given as a slow intravenous (I.V.) push over 10 minutes. Two treatment days one week apart followed by a 12-week safety period. Duration of Patient Participation: Due to the sequential design, the total duration of this study was not fixed. Originally, the study was planned in a randomized, parallel-group, group sequential design. Objective : The primary objective of this study was an inferential comparison between the 2 randomized groups in terms of overall survival using a group sequential triangular test ,since the study was prematurely terminated the pre-planned group-sequential nature of the study design was not applicable statistical analyses. Actually, the prominent efficacy variables for the OS and DFS were analysed in the FAS (identical to the safety analysis set) and PPS using Kaplan Meier estimates by treatment group. Study Design : This study was designed as a prospective, multi-center, open label, randomized, two-armed, group-sequential Phase III study. The study was planned to consist of 2 stages: an interventional Stage 1 with Screening/Baseline, treatment, safety, and follow-up periods, and a non-interventional Stage 2 consisting of a long-term follow-up period (until completion of a median observation period of 5 years). This second stage of the study was to be started only if superiority of the Zevalin study regimen could be demonstrated in the preceding Stage 1. Pharmacokinetics/Pharmacodynamic results: Not applicable Extent of exposure: All 34 patients randomized to the Zevalin arm were given 2 rituximab infusions(with a median dose of 425.0 mg at each of the 2 infusion time points).Three patients underwent radioimaging studies/dosimetry and therefore were administered [111In]-ibritumomab tiuxetan at Day 1. All but 1 patient received an infusion with [90Y]-ibritumomab tiuxetan following the second infusion of rituximab. The mean dose ranged from 765.9 -1197.0 MBq.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Overall Survival (OS)	The primary analysis was based on the full analysis set (FAS). Actually, the prominent efficacy variable OS was analysed in the FAS (identical to the safety analysis set) and Per Protocol Set using Kaplan Meier estimates by treatment group. "Overall survival" was defined as the median time interval (in months)from randomization to death from any cause.This time-to-event variable was censored at the date of the last known follow-up visit (provided that the patient was still alive at that time).	5 years or until patient dies or lost to follow up
Secondary	Proportion of Participants With Disease Free Survival (DFS)	DFS was analysed in the FAS (identical to the safety analysis set) and Per Protocol set using Kaplan Meier estimates by treatment group.Disease-free survival was defined as the median time interval (in months) from randomization to the date of relapse (as assessed by the investigator) or death from any cause. This time-to-event variable was also censored at the date of the last known follow-up visit (provided that the patient was still alive at that time).	5 years or until patient disease progresses or lost to follow up
Secondary	The Health-related Quality of Life (HRQL)	HRQL questionnaire consists of 27 questions each scores ranging from 0 - 4. The minimum score was 0 which is termed as 'worst imaginable health state' and the maximum score for a patient was 100 which is termed as 'best imaginable health state'.; The descriptive classification defines health status in terms of 5 dimensions: mobility, self-care, usual activity, pain/discomfort, and anxiety/depression. Each dimension is subdivided into 3 levels: no problem, some or moderate problems, unable or extreme problems.	Up to Month 36
