Trial Outcomes & Findings for S0801 Iodine I 131 Tositumomab, Rituximab, and Combination Chemotherapy in Previously Untreated Stage II, Stage III, or Stage IV Follicular Non-Hodgkin Lymphoma (NCT NCT00770224)

NCT ID: NCT00770224

Last Updated: 2019-08-28

Results Overview

Measured from date of registration to date of first observation of progressive disease or death due to any cause. Progressive disease is ≥ 50% increase in the sum of products of greatest diameters (SPD) of target measurable nodal lesions over the smallest sum observed (over baseline if no decrease during therapy), or ≥ 50% increase in the greatest transverse diameter (GTD) of any node \> 1 cm in shortest axis, or ≥ 50% increase in the SPD of other target measurable lesions (e.g., splenic or hepatic nodules) over the smallest sum observed. Appearance of any new bone marrow involvement; appearance of a new lesion/site; lymph nodes with the long axis is \> 1.5 cm, or if the both the long and short axes are \> 1 cm; in patients with no pretreatment PET scan or when the PET scan was positive before therapy, lesions should be PET positive; or death due to disease without prior documentation of progression.

SECONDARY outcome

Timeframe: up to 5 years (1 year induction + 4 years maintenance therapy) or time of disease progression

Population: Eligible and evaluable patients were included in the analysis.

Complete (CR), complete unconfirmed (CRU) and partial responses (PR). CR is complete disappearance of all measurable and non-measurable disease with the exception of the following. Positron emission tomography (PET) must be negative if no pre-treatment PET scan or when the PET was positive before therapy. If the PET scan was negative before therapy, all nodal masses must have regressed. no new lesions; previously enlarged organs must have regressed in size; and if bone marrow positive at baseline, it must be negative. PR is ≥ 50% decrease in sum of products of greatest diameters (SPD) for up to six identified dominant lesions identified at baseline; no new lesions; no increase in the size of liver, spleen or other nodes; and splenic and hepatic nodules must have regressed in size by at least 50% in SPD. In patients with no pre-treatment PET scan or when the PET scan was positive before therapy, PET should be positive in at least one previously involved site.

Population: Eligible patients who had received any treatment were included in the adverse event summaries. Any CTCAE 4.0 event of Grade 3 (severe), Grade 4 (life threatening), or Grade 5 (fatal) which deemed to be related to protocol treatment are included.

Adverse Events (AEs) are reported by the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. For each patient, worst grade of each event type is reported. Grade 3 = Severe, Grade 4 = Life-threatening, Grade 5 = Fatal.
