First participant will receive intravenous (injection of a substance into a vein) 0.005 milligram per kilogram (mg/kg) (planned dose) infusion of daratumumab and other participants will receive different doses. The participants will receive 7 full infusions of daratumumab and 2 predose infusions every 2 weeks. The dose of daratumumab will be escalated sequentially and considering the safety and efficacy of dose in Part 1, dose for Part 2 of the study will be decided. A predose infusion of 10% of the full dose of daratumumab will be administered a day before the first 2 full infusions.

Part 1: Daratumumab

In Part 2, the participants will receive dose of daratumumab as determined in part 1 (16 mg/kg) of the study. Participants will receive 8 full infusions at weekly intervals followed by biweekly (every 2 weeks) infusions for 16 additional weeks and monthly infusions until disease progression or unmanageable toxicity, whichever comes first. Predose was dropped at some point in Part 2. A predose infusion of 10 mg daratumumab will be administered on the day before the first full infusion in select cohorts.

Part 2: Daratumumab

Pre-dose: Participants (part 1) will receive methylprednisolone 80 mg intravenous (IV) injection 30 minutes to 2 hours before treatment. Participants (part 2) will receive 100 mg methylprednisolone IV 60 minutes to 2 hours before treatment; if a patient experiences no significant infusion-related reactions, the dose of methylprednisolone may be decreased to 50 mg after Visit 4.

Post-dose: All participants (part 1) will receive 40 mg methylprednisolone orally on the first and the second day after all full infusions. During Part 2, all participants will receive 20-25 mg methylprednisolone orally or equivalent on the first and second days after all full-dose infusions.

Participants (Part 2) will receive 20 mg dexamethasone intravenous (IV) injection pre-dose, on the first and second days after every full-dose infusions.

Janssen Research & Development, LLC Clinical Trial

Establishment of safety profile of HuMax-CD38 when given as monotherapy in participants with multiple myeloma relapsed from or refractory to at least 2 different cytoreductive therapies and without further established treatment options.

This study is conducted in two parts. In part I, participants are enrolled into cohorts at increasing dose levels. Participant safety and efficacy during part I will determine the doses used for Part II. In part II participants will be enrolled into one of two sequential treatment arms using two of the doses defined in part 1 of the study. Part II was 5 cohorts, 3 with 8 milligram per kilogram (mg/kg) and 2 with 16 mg/kg. Part I and all but the last cohort in Part II were dosed with Phase 1/ 2 drug product. The last cohort in Part II was dosed with Phase 3 drug product. Both Part I and Part II are open-label/unmasked.

Daratumumab (HuMax®-CD38) Safety Study in Multiple Myeloma

Daratumumab (HuMax®-CD38) Safety Study in Multiple Myeloma - Open Label, Dose-escalation Followed by Open Label, Single-arm Study

An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. A serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.

Overall response defined as percentage of participants who achieved stringent complete response (sCR), complete response (CR), very good partial response (VGPR) or partial response (PR). Per IMWG criteria, sCR: is defined as normal free light chain (FLC) ratio, and absence of clonal plasma cells (PCs) by immunohistochemistry, immunofluorescence or 2- to 4-color flow cytometry; CR: Negative immunofixation on the serum and urine and disappearance of any soft tissue plasmacytomas and \< 5 % plasma cells in bone marrow; VGPR: Serum and urine M-protein detectable by immunofixation but not on electrophoresis or \>= 90% reduction in serum M-protein plus urine M-protein level \< 100mg/24 hours; PR: \>= 50 % reduction of serum M-protein and reduction in 24 hour urinary M-protein by \>= 90% or to \<200 mg/24 hours; if the serum and urine M-protein are not measurable, a decrease of \>=50% in the difference between involved and uninvolved FLC levels is required in place of the M-protein criteria.

Time to first response was defined as the time from the date of first dose of daratumumab to the date of initial documentation of a response (PR or better). Time to best response was defined as the time between the date of first dose of daratumumab and the date of the initial evaluation of the best response (PR or better) to treatment. Kaplan-Meier method was used to estimate the distribution of time to response and time to best response.

TTP was defined as the number of days from the date of first infusion (Day 1) to the date of first record of disease progression. Disease progression (IMWG criteria): increase of 25 percent (%) from lowest response level in Serum M-component and/or (the absolute increase must be \>=0.5 g/dL); urine M-component and/or (the absolute increase must be \>=200 mg/24 hour; only in participants without measurable serum and urine M-protein levels: the difference between involved and uninvolved free light chain levels (absolute increase must be \>10 mg/dL); Development of hypercalcemia (corrected serum calcium \>11.5 mg/dL or 2.65 mmol/L) that can be attributed solely to the plasma cell proliferative disorder. Median TTP was estimated by using the Kaplan-Meier method.

Duration of response was calculated from the date of initial documentation of a response (PR or better) to the date of first documented evidence of progressive disease, as defined in the International Myeloma Working Group (IMWG) criteria.

Progression free survival (PFS) was defined as the time between the date of first dose of daratumumab and either disease progression or death, whichever occurs first.

Time to first response was defined as the time from the date of first dose of daratumumab to the date of initial documentation of a response (PR or better). Time to best response was defined as the time between the date of first dose of daratumumab and the date of the initial evaluation of the best response (PR or better) to treatment. Time to VGPR (very good partial response) was defined as the time from the date of first dose of daratumumab to the date of initial documentation of VGPR response. The Kaplan-Meier method was used to estimate time to response.

Overall Survival (OS) was defined as the number of days from administration of the first infusion (Day 1) to date of death. Median Overall Survival was estimated by using the Kaplan-Meier method.
