Study summary

This is a multicenter, open-label, single-arm, expanded access treatment study designed to provide obinutuzumab to patients with previously untreated Chronic Lymphocytic Leukemia (CLL) in combination with chlorambucil and to evaluate the safety and efficacy of obinutuzumab administered in combination with chlorambucil. This study will enroll patients with previously untreated CD20-positive CLL requiring treatment according to the IWCLL guidelines (Hallek et al 2008), as assessed by the investigator.

Study arms

  • Experimental
    Obinutuzumab + Chlorambucil

    Obinutuzumab was administered intravenously for 6 cycles (28-day cycles) as: 100 mg on Day 1, 900 mg on Day 2, and 1000 mg on Days 8 and 15 for Cycle 1; and 1000 mg on Day 1 of Cycles 2 to 6. Chlorambucil was administered orally at a dose of 0.5 mg/kg body weight on Days 1 and 15 for Cycles 1 through 6 (28-day cycles).

What researchers measure

Primary outcomes

  1. Number of Participants Who Received Obinutuzumab and Chlorambucil in the Study

    Number of participants who received obinutuzumab and chlorambucil in the study are presented in the below table.

    Time frame: Cycles 1 to 6 (28-day cycles)

Secondary outcomes

  1. Number of Participants With Adverse Events (AEs), AEs of Grade 3 and Above Severity, AEs of Special Interest (AESI), AEs Leading to Obinutuzumab Discontinuation or Dose Delays, Serious Adverse Events (SAEs), and Death

    An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered to be related to the medicinal product. National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), version 4.0 was used for grading the AEs. According to NCI CTCAE, Grade 3 = severe or medically significant but not immediately life threatening; Grade 4 = life-threatening consequences, urgent intervention indicated, and Grade 5 = death. AESIs included all tumor lysis syndrome, serious infections, serious infusion-related reactions (IRR), and hepatitis B reactivation. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, or results in a congenital anomaly/birth defect.

    Time frame: Up to 28 days after the last dose of study drug (up to 7 months from Day 1)

  2. Number of Participants With Objective Response

    Objective response is defined as either complete response \[CR\], complete response with incomplete recovery \[CRi\], or partial response \[PR\] as determined by the treating physician's standard practice at the end of treatment or premature discontinuation from study per the International Workshop on Chronic Lymphocytic Leukemia Criteria (iwCLL criteria). Patients who have not achieved a CR or a PR, and who have not exhibited progressive disease, will be considered to have stable disease (which is equivalent to a nonresponse).

    Time frame: Up to end of treatment or premature discontinuation from study (up to 7 months from Day 1)
