Outcomes

Primary Outcomes

Number of Participants With Dose Limiting Toxicities (DLTs)

A DLT was graded using the National Cancer Institute-Common Toxicity Criteria for Adverse Events (NCI-CTCAE) version 4.02 and defined as any of the following: grade 3 or 4 non-hematologic adverse events unless they were not optimally treated with supportive care; grade 3 or 4 asymptomatic laboratory abnormal values lasting \>7 days; prolonged grade 2 toxicity (lasting more than 2 weeks) leading to treatment interruption and/or dose reduction; pancytopenia with a hypocellular bone marrow and no marrow blasts lasting ≥6 weeks (AL participants); grade 3 neutropenia with fever or infection (OHM participants); grade 3 thrombocytopenia with bleeding (OHM participants); or grade 4 neutropenia or thrombocytopenia, regardless of symptoms and lasting ≥3 days (OHM participants).

Time frame: Cycle 1 (Up to 21 days)

Secondary Outcomes

Number of Participants Who Experienced at Least One Adverse Event (AE)

AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which did not necessarily have to have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product/protocol specified procedure, whether or not considered related to the medicinal product/protocol specified procedure. Any worsening of a preexisting condition temporally associated with the use of the product was also an AE. AEs were collected during the entire time frame of treatment plus up to 40 days of follow-up.

Time frame: Up to 40 days after last dose of study therapy (Up to 28 months)

Number of Participants Who Discontinued Study Therapy Due to AEs

All participants who discontinued study therapy due to an AE at any time during treatment.

Time frame: From time of first dose of study therapy until the end of treatment (up to 26 months)

Number of Participants Whose Best Response Was Partial Response (PR) or Complete Response (CR)

Best response was determined from the start of treatment until disease progression, recurrence, or completion of 26 months of treatment. Partial and complete response was assessed by bone marrow aspiration (AL participants); or computed tomography scan, magnetic resonance imaging, positron emission tomography, or X-ray (OHM participants) using standard criteria. Acute leukemia participants were assessed based on the recommendations from the European LeukemiaNet Döhner 2010); lymphoma participants according to Cheson 2007; and MM participants according to Durie 2006.

Time frame: From time of first dose of study therapy until the end of treatment (up to 26 months)
