A Study of MabThera/Rituxan (Rituximab) Alone and in Combination With Roferon-A in Patients With Follicular or Other CD20+ Low-Grade (Indolent) Lymphoma

August 29, 2014 updated by: Hoffmann-La Roche

Rituximab (Mabthera®) as Single Agent and in Combination With Interferon Alfa-2a (Roferon-A®), a Phase-III Randomized Trial in Patients With Follicular or Other CD20+ Low-grade (Indolent) Lymphoma

This randomized, open-label study will compare the efficacy and safety of MabThera/Rituxan (rituximab) alone, and in combination with Roferon-A (interferon alfa-2a) in patients with follicular or other CD20+ low-grade lymphoma. Patients will be randomized to receive either MabThera/Rituxan 375 mg/m2 intravenously weekly for 4 weeks or Roferon-A 3 MIU/day subcutaneously in Week 1 followed by 4.5 MIU/day sc in Weeks 2-5 plus MabThera/Rituxan 375 mg/m2 weekly iv in Weeks 3-6. Patients who have a response will receive an additional cycle of treatment. The anticipated time on study treatment is up to 6 months.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Treatment Failure - Percentage of Participants With an Event
Time Frame: Baseline (BL), Week 10 and 16, and Months 6, 12, 18, 24, 30, and 42 of the follow-up period
Treatment failure was defined as an event of any of the following: progressive disease while receiving study treatment, death due to any cause, or the initiation of another type of treatment due to stable disease, progressive disease or relapse, or intolerance to study treatment.
Baseline (BL), Week 10 and 16, and Months 6, 12, 18, 24, 30, and 42 of the follow-up period
Treatment Failure - Time to Event
Time Frame: BL, Week 10 and 16, and Months 6, 12, 18, 24, 30, and 42 of the follow-up period
The median time, in months, between randomization and treatment failure event determined using Kaplan-Meier estimates.
BL, Week 10 and 16, and Months 6, 12, 18, 24, 30, and 42 of the follow-up period

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants Achieving Complete Response (CR), Unconfirmed CR (CRu), or Partial Response (PR)
Time Frame: Weeks 10 and 16
CR was defined as the complete disappearance of all previously detectable disease signs; the absence of palpable lymph nodes greater than (>) 1 centimeter (cm) or nodes >1.5 cm observed in computerized axial tomography (CAT) scan; and negative bone marrow pathology, if initially positive. CRu was defined as CR, except that bone marrow results were indeterminate. PR was defined as a decrease of greater than or equal to (≥) 50 percent (%) compared with the BL value in the sum of the products of the two largest perpendicular diameters in all measurable and evaluable lesions; and a ≥50% reduction of the size from BL if hepato-splenomegaly was present.
Weeks 10 and 16
Percentage of Participants Achieving CR or CRu
Time Frame: Weeks 10 and 16
CR was defined as the complete disappearance of all previously detectable disease signs; the absence of palpable lymph nodes >1 cm or nodes >1.5 cm observed in CATscan; and negative bone marrow pathology, if initially positive. CRu was defined as CR, except that bone marrow results were indeterminate.
Weeks 10 and 16
Duration of Response - Percentage of Participants With an Event
Time Frame: BL, Week 10 and 16, and Months 6, 12, 18, 24, 30, and 42 of the follow-up period
Response duration was defined as the period between the date for first observation of CR, CRu or PR and the date of progressive disease (PD), censored observation or death of any cause. Response duration was also assessed for response defined as CR only. Response duration was calculated among responders (CR+CRu+PR) with cutoffs for follow-up applied.
BL, Week 10 and 16, and Months 6, 12, 18, 24, 30, and 42 of the follow-up period
Duration of Response
Time Frame: BL, Week 10 and 16, and Months 6, 12, 18, 24, 30, and 42 of the follow-up period
The median time, in months, from the date of the first observation of CR, CRu, or PR and the date of progressive disease (PD), censored observation, or death due to any cause. PD was defined as an increase of >50% compared to BL in the sum of the product of the two largest perpendicular parameters of measurable lymphoma, or the occurrence of new lesions. One month=30.4 days. Response duration was calculated amongst responders (CR+CRu+PR) with cutoffs for follow-up applied.
BL, Week 10 and 16, and Months 6, 12, 18, 24, 30, and 42 of the follow-up period

The median time, in months, from randomization to disease progression event assessed using Kaplan-Meier estimates. One month=30.4 days
BL, Week 10 and 16, and Months 6, 12, 18, 24, 30, and 42 of the follow-up period
Overall Survival (OS) - Percentage of Participants With an Event
Time Frame: BL, Week 10 and 16, and Months 6, 12, 18, 24, 30, and 42 of the follow-up period
An overall survival event was defined as death due to any cause.
