Trial Outcomes & Findings for A Dose-Escalating Study of Obinutuzumab in Patients With B-lymphocyte Antigen (CD20+) Malignant Disease (GAUGUIN) (NCT NCT00517530)

NCT ID: NCT00517530

Last Updated: 2016-10-11

Results Overview

Dose-limiting toxicities were defined as obinutuzumab-related adverse events occurring within the first 28 days of each administration of obinutuzumab, with the exception of B-cell depletion and lymphopenia which are expected outcomes of treatment with obinutuzumab.

Recruitment status

COMPLETED

Study phase

PHASE1/PHASE2

Target enrollment

134 participants

Primary outcome timeframe

Baseline to 28 days after the last infusion of obinutuzumab (up to 6 months)

Results posted on

Participant Flow

Different patients were recruited into Phase I and Phase II, and analyzed separately based on their disease. In this adaptive trial design, some of those same patients were included in follow-up even if they did not complete treatment, and 13 who had initially responded to treatment but subsequently progressed were retreated.

SECONDARY outcome

A complete response was defined as the disappearance of all evidence of disease (NHL) and symptoms; normalization of biochemical abnormalities (NHL); regression of lymph nodes and nodal masses to normal size; decrease of nodes in the sum of the products of the greatest diameters (SPD); regression in size of the spleen and/or liver, should not be palpable, and disappearance of nodules related to lymphoma (CLL). Complete/unconfirmed (CRu) response includes NHL patients with one or more of the following: 1) a residual lymph node mass greater than 1.5 cm in greatest transverse diameter that has regressed by more than 75% in the SPD; 2) Indeterminate bone marrow (increased number or size of aggregates without cytologic or architectural atypia). Complete Response with Incomplete Bone Marrow Recovery (CRi) was measured only in patients with CLL.

Population: Safety population: All enrolled participants in Phase II, who had received at least 1 dose of obinutuzumab.

PFS was defined as the time from start of treatment to disease progression (PD) or death due to any cause, whichever occurred first. For non-Hodgkin's lymphoma participants, PD was defined as \>= 50% increase from nadir in the sum of the products of the greatest diameters (SPD) of any previously identified abnormal node for participants with a partial response or non-responders or the appearance of any new lesion during or at the end of therapy. For chronic lymphocytic leukemia participants, PD was defined as: (1) A \>= 50% increase from nadir in the SPD of any previously involved nodes, or in a single involved node, or the size of other lesions (eg, splenic or hepatic nodules); a lymph node with a short axis of \< 1.0 cm must increase by \>= 50% and to a size of 1.5×1.5 cm or \> 1.5 cm in the longest axis. (2) Appearance of any new lesion \> 1 cm in the short axis. (4) A new site that is positron emission tomography (PET)-positive with histological confirmation.

Population: Participants analyzed include those with B-cell depletion at the end of treatment (N), with assessments (n) at each time point.

B-cell depletion was defined in two ways: definition 1 - decrease below 5% baseline level and definition 2 - decrease below 0.04 x 109/L. B-cell recovery was defined in two ways: definition 1 - return to at least 50% of baseline level and definition 2 - return to at least 0.08 x 109/L.

Timeframe: at Cycle 1 Day 1, Cycle 1 Day 8 and Cycle 8 (over 168 days)

Population: Pharmacokinetics (PK)- evaluable population at the given dose (e.g., 3 or more participants at any of the given time points). Other doses did not have a PK-evaluable population, so were not included in the table of results. Due to the limited sampling schedule derived PK parameters could not be accurately obtained during Cycle 1 and Cycle 8.

SECONDARY outcome

Timeframe: Day 1 of Cycle 1

Population: Pharmacokinetics (PK)- evaluable population at the given dose (e.g., 3 or more participants). Other doses did not have a PK-evaluable population, so were not included in the table of results. Due to the limited sampling schedule derived PK parameters could not be accurately obtained during Cycle 1 and Cycle 8.

Blood samples were taken on Day 1 (pre-infusion, end of infusion, 3-6 hours post-infusion) of Cycle 1. Nonlinear mixed-effects modeling (with NONMEM software) was used to analyze the pooled samples for dose-concentration-time data of obinutuzumab.
