The Grade 3 and 4 hematology laboratory test values by treatment group in
the randomized CLL clinical study are described in Table 2. These findings
confirm the myelosuppressive effects seen in patients treated with benda-
mustine hydrochloride. Red blood cell transfusions were administered to
20% of patients receiving bendamustine hydrochloride compared with 6%
of patients receiving chlorambucil.

In the randomized CLL trial, 34% of patients had bilirubin elevations,
some without associated significant elevations in AST and ALT. Grade 3
or 4 increased bilirubin occurred in 3% of patients. Increases in AST and
ALT of Grade 3 or 4 were limited to 1% and 3% of patients, respectively.
Patients treated with bendamustine hydrochloride may also have changes
in their creatinine levels. If abnormalities are detected, monitoring of these
parameters should be continued to ensure that significant deterioration does
not occur.

Clinical Trials Experience in NHL
The data described below reflect exposure to bendamustine hydrochloride
in 176 patients with indolent B-cell NHL treated in two single-arm studies.
The population was 31-84 years of age, 60% male, and 40% female. The
race distribution was 89% White, 7% Black, 3% Hispanic, 1% other, and
<1% Asian. These patients received bendamustine hydrochloride at a dose
of 120 mg/m 2 intravenously on Days 1 and 2 for up to eight 21-day cycles.
The adverse reactions occurring in at least 5% of the NHL patients,
regardless of severity, are shown in Table 3. The most common non-
hematologic adverse reactions (≥30%) were nausea (75%), fatigue (57%),
vomiting (40%), diarrhea (37%) and pyrexia (34%). The most common
non-hematologic Grade 3 or 4 adverse reactions (≥5%) were fatigue (11%),
febrile neutropenia (6%), and pneumonia, hypokalemia and dehydration,
each reported in 5% of patients.
