Dosimetry/Validation Study of 131Iodine-Anti B1 (Murine) Radioimmunotherapy for Chemotherapy Refractory Low Grade B Cell Lymphomas and Low Grade Lymphomas That Have Transformed to Higher Grade Histologies (RIT-II-001)
October 28, 2016 updated by: GlaxoSmithKline
Multicenter, Phase II Dosimetry/Validation Study of 131Iodine-Anti B1 (Murine) Radioimmunotherapy for Chemotherapy Refractory Low Grade B Cell Lymphomas and Low Grade Lymphomas That Have Transformed to Higher Grade Histologies
Study RIT-II-001 is a phase II, multicenter study of the safety, tumor and organ dosimetry, dosimetry methods, and efficacy of Iodine-131 Anti-B1 Antibody for the treatment of patients with low-grade or transformed low-grade non-Hodgkin's lymphoma (NHL).
The primary objective of this study is to demonstrate that each site could accurately conduct the whole body dosimetry required for the safe and effective dosing of Iodine-131 Anti-B1 Antibody.
Additional objectives of this study are to evaluate the efficacy, dosimetry, and safety of Iodine-131 Anti-B1 Antibody.

Description
Inclusion Criteria

---|---|
EXPERIMENTAL: Tositumomab and Iodine I-131 Tositumomab
Patients receive a dosimetric dose consisting of 450 milligrams (mg) of unlabeled tositumomab (TST, Anti-B1 Antibody) intravenously (IV) followed by 5 milliCurie (mCi) of Iodine I 131 TST IV.
Serial whole body sodium iodide probe scintillation counts and whole body conjugate view gamma camera scans obtained approximately 1 hour after administration and then daily for the next 7 days were used to determine the radioactive clearance and the dose of iodine I 131 TST required to deliver a 75 centigray (cGy) therapeutic dose.
The therapeutic dose was administered 7-14 days after the dosimetric dose and consisted of TST 450 mg and an activity of Iodine 131 calculated to deliver 75 cGy or 65 cGy of total body irradiation, depending on platelet count, and 35 mg TST.

Based on their platelet count and body weight.
Participants received different TDs of TST.
For obese participants (weighing more than 137% of their calculated lean body weight), the calculation to determine the administered activity (mCi) was performed using the maximum effective mass (i.e., the minimum of the participant's mass and 137% of their calculated lean body weight).
The administered activity (mCi) for participants with a Baseline platelet count of 100001-149999 cells/millimeter cubed (mm^3) was reduced to a 65 cGy total body dose, after any adjustment for obesity.
