February 5, 2020 updated by: Hoffmann-La Roche
Phase II Trial to Evaluate The Efficacy of Obinutuzumab (RO5072759) + Bendamustine Treatment in Patients With Refractory Or Relapsed Chronic Lymphocytic Leukemia
This phase II trial was designed to evaluate the efficacy of obinutuzumab and bendamustine treatment in participants with refractory or relapsed chronic lymphocytic leukemia (CLL).
Participants receive up to six 28-day cycles of treatment.
Treatment consists of intravenous (IV) administration of obinutuzumab and bendamustine.
Treatment time is expected to last 6 months, and participant follow-up will last 2 years.

An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product.
Preexisting conditions which worsen during a study are also considered as AEs.
An SAE was any AE that was any of the following: fatal, life-threatening, required or prolonged inpatient hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/ birth defect, and was considered a significant medical event by the investigator.

Up to approximately 4.5 years
|
Percentage of Participants With Infusion-related Reactions (IRRs)
