Inclusion criteria:
Phase 1:
- For dose escalation cohorts, participants with confirmed selected CD38+
hematological malignancies as specified below who had progressed on after standard
therapy or for whom there was no effective standard therapy (refractory/relapsed
participants). B-cell Non-Hodgkin-lymphoma/leukemia (NHL) participants with at least
1 measurable lesion. Multiple myeloma (MM) participants with measurable M-protein
serum and/or 24-hour urine. Acute myeloid leukemia (AML) participants, all types
except M3 based on French-American-British (FAB) classification. Acute Lymphoblastic
Leukemia (B-cell ALL) participants. Chronic lymphocytic leukemia (CLL) participants.
- For expansion cohorts, participants with relapsed/refractory MM with measurable
M-protein (serum M-protein of >0.5 g/dL and/or urine M-protein of >200 mg (24-hr
urine)) or elevated serum free light chains (FLC) >10 mg/dL with abnormal FLC ratio)
who had progressed on or after standard therapy that included an Immunomodulatory
drug (IMiD) and a proteasome inhibitor and who met the protocol defined criteria for
standard risk or high risk.
Phase 2:
- Participants had a known diagnosis of multiple myeloma with evidence of measurable
disease, and have evidence of disease progression based on International Myeloma
Working Group (IMWG) criteria: Serum M-protein ≥1 g/dL, or urine M-protein >=200
mg/24 hours or in the absence of measurable m-protein, serum FLC >=10 mg/dL, and
abnormal serum immunoglobulin kappa lambda FLC ratio (<0.26 or >1.65).
- Participants who received at least three prior lines of therapy for MM and had
treatment with an IMiD (for >=2 cycles or >=2 months of treatment) and a proteasome
inhibitor (PI) (for >=2 cycles or >=2 months of treatment) OR participants whose
disease was double refractory to an IMiD and a PI. For participants who had received
more than 1 type of IMiD and PI, their disease must be refractory to the most recent
one.
- Participants who had achieved a minimal response or better to at least one prior
line of therapy.
- Participants who had received an alkylating agent (>=2 cycles or >=2 months) either
alone or in combination with other MM treatments.
- Stage 2 only: Participants who had evidence of disease progression on or after the
most recent prior regimen based on IMWG criteria.
Exclusion criteria:
Phase 1:
- Karnofsky performance status <60
- Poor bone marrow reserve
- Poor organ function
- Known intolerance to infused protein products, sucrose, histidine, polysorbate 80 or
known hypersensitivity to any of the components of the study therapy that was not
amenable to pre-medication with steroids and H2 blockers
- Any serious active disease (including clinically significant infection that was
chronic, recurrent, or active) or co-morbid condition, which, in the opinion of the
investigator, interfered with the safety, the compliance with the study or with the
interpretation of the results
- Any severe underlying medical conditions including presence of laboratory
abnormalities, which could impair the ability to participate in the study or the
interpretation of its results
Phase 2:
- Participants with multiple myeloma immunoglobulin M (IgM) subtype
- Previous treatment with any anti-CD38 therapy
- Participants with concurrent plasma cell leukemia
- Participants with known or suspected amyloidosis
- Karnofsky performance status <60 (stage 1)/Eastern Cooperative Oncology Group (ECOG)
Performance status >2 (stage 2).
- Poor bone marrow reserve
- Poor organ function
- Known intolerance to infused protein products, sucrose, histidine, polysorbate 80 or
known hypersensitivity to any of the components of the study therapy that was not
amenable to pre-medication with steroids and H2 blockers
- Any serious active disease (including clinically significant infection that was
chronic, recurrent, or active) or co-morbid condition, which, in the opinion of the
investigator, interfered with the safety, the compliance with the study or with the
interpretation of the results
- Any severe underlying medical conditions including presence of laboratory
abnormalities, which impaired the ability to participate in the study or the
interpretation of its results
