Trial Outcomes & Findings for Intrathecal Rituximab in Lymphoid Malignancies Involving Central Nervous System (NCT NCT01596127)

NCT ID: NCT01596127

Last Updated: 2018-05-24

Results Overview

The percentage of participants whose cancer shrinks or disappears after treatment where participants are considered as responding to therapy if the Cerebrospinal fluid (CSF) is without evidence of blast cells after four lumbar punctures with rituximab.

Participant Flow

Recruitment: 1/24/2013 through 11/13/2013. All participants recruited at The University of Texas MD Anderson Cancer Center.

Four patients were enrolled and three participants were evaluable for safety and efficacy and toxicity. One patient was ineligible and therefore was never treated. Due to lack of response and slow accrual, the study was terminated early.

Measure
Intrathecal Rituximab
Phase I Starting Dose: Rituximab administered via lumbar puncture at dose of 10 - 25 mg twice weekly according to the dose escalation. Phase II Rituximab Starting Dose: Maximum tolerated dose from Phase I. Intrathecal Rituximab: Phase I: Starting dose Rituximab 10 mg intrathecally twice weekly until 2 consecutive CSF samples are negative for the presence of blast cells. Thereafter, rituximab 10 mg intrathecally weekly for additional 4 weeks, followed by intrathecal rituximab 10 mg administered once every other week for an additional 8 weeks. Phase II Starting Dose of Rituximab: Maximum tolerated dose from Phase I.

SECONDARY outcome

Timeframe: 2 weeks

Population: Multiple dose levels were designed with a starting dose of 10 mg per injection followed by 25 mg once safety was established in the first 3 patients treated at the first dose level. The study moved tot he next dose level. Due to lack of response and slow accrual, participants were never treated on the next dose level and the study was terminated

MTD is dose level at which at least 1 of 3 participants experiences a dose-limiting toxicity (DLT). DLTdefined as clinically significant adverse event or abnormal laboratory value assessed as unrelated to disease progression, intercurrent illness, or concomitant medications and meeting the NCI common terminology criteria that are CTCAE Grade 3 or 4.
