Brief Summary:
This is an open-label, multicentre, dose escalation study to characterize the safety and preliminary efficacy of the human anti-CD38 antibody MOR03087 (MOR202), in adult subjects with relapsed/refractory multiple myeloma, as monotherapy and in adult subjects with relapsed/refractory multiple myeloma in combination with standard therapy.

Condition or disease Intervention/treatment Phase
Multiple Myeloma Drug: MOR03087 phase 1 dose escalation Drug: MOR03087 Drug: Dexamethasone Drug: Pomalidomide Drug: Lenalidomide Phase 1 Phase 2

Detailed Description:
The study enrolled patients aged 18 years or older with relapsed or refractory multiple myeloma and Karnofsky performance status of 60% or higher. Patients were assigned to the different treatment regimens with MOR202 ranging between 0·01 mg/kg and 16 mg/kg in a 3 + 3 design. Dose-escalation and expansion was done either with MOR202 intravenous infusions alone (MOR202 q2w [twice a week] and q1w [weekly] groups) or in combination with dexamethasone (MOR202 with dexamethasone group), with dexamethasone plus pomalidomide (MOR202 with dexamethasone plus pomalidomide group) or plus lenalidomide (MOR202 with dexamethasone plus lenalidomide group). Primary endpoints were safety, MOR202 maximum tolerated dose (or recommended dose) and regimen, and immunogenicity.

Arm Intervention/treatment
Experimental: Phase 1 dose escalation

Part A: MOR03087 dose escalation; biweekly treatment

Part B: MOR03087 dose escalation; weekly treatment

Part C: MOR03087 dose escalation (weekly treatment) + dexamethasone

Part D: MOR03087 weekly treatment in combination with pomalidomide + dexamethasone

Part E: MOR03087 weekly treatment in combination with lenalidomide + dexamethasone

For all parts, patients will be treated until disease progression (PD) or until a maximum of 3 years after first treatment.

Drug: MOR03087 phase 1 dose escalation

Treatment cycles will be 28 days. Initial MOR03087 doses will be 0.01 mg/kg in part A, 4 mg/kg in parts B and C and 8 mg/kg in parts D and E; in all parts MOR03087 doses will be escalated to a maximum of 16 mg/kg. In part A, patients will receive a biweekly intravenous infusion of MOR03087 which will be administered on days 1 and 15 of the cycle. In parts B to E patients will receive a weekly intravenous infusion of MOR03087 which will be administered on days 1, 8, 15, and 22 of the cycle.

In all parts a loading dose of MOR03087 will be additionally administered on day 4 of cycle 1.


Drug: Dexamethasone
Dexamethasone will be administered to patients orally; 40 mg (≤ 75 years old) or 20 mg (> 75 years old) on days 1, 8, 15, and 22 of the 28-day cycle. An additional dose will be administered in cycle 1 on day 4.

Drug: Pomalidomide
Pomalidomide will be administered to patients orally 4 mg on days 1-21 of the 28-day cycle.

Drug: Lenalidomide
Lenalidomide will be administered to patients orally 25 mg on days 1-21 of the 28-day cycle.

Experimental: Phase 2a confirmatory cohorts

Confirmatory cohorts of MOR03087 monotherapy (plus or minus dexamethasone), in combination with pomalidomide plus dexamethasone, and in combination with lenalidomide plus dexamethasone.

Following completion of Parts A, B, and C (dose escalation of MOR03087 biweekly and weekly schedules), the Maximum Tolerated Dose (MTD) or recommended dose and dosing regimen will be confirmed in a minimum of 6 subjects.

Following completion of Parts D (dose escalation of MOR03087 in combination with pomalidomide + dexamethasone) and E (dose escalation of MOR03087 in combination with lenalidomide + dexamethasone), the MTD and/or recommended dose in each part will be confirmed in a minimum of 6 subjects.

For all parts, patients will be treated until PD or until a maximum of 3 years after first treatment.

Drug: MOR03087
MOR03087 will be administered according to the Maximum Tolerated Dose (MTD) or recommended dose and dosing regimen for MOR03087 from parts A-E of the phase I dose escalation. The biweekly MOR03087 regimen as described in part A; the weekly regimen as described for parts B-E.

Drug: Dexamethasone
Dexamethasone will be administered to patients orally; 40 mg (≤ 75 years old) or 20 mg (> 75 years old) on days 1, 8, 15, and 22 of the 28-day cycle. An additional dose will be administered in cycle 1 on day 4.

Drug: Pomalidomide
Pomalidomide will be administered to patients orally 4 mg on days 1-21 of the 28-day cycle.

Drug: Lenalidomide
Lenalidomide will be administered to patients orally 25 mg on days 1-21 of the 28-day cycle.




Primary Outcome Measures :
  1. Determination of Maximum Tolerated Dose and / or Recommended Dose and Dosing Regimen of MOR03087 [ Time Frame: First cycle of treatment ]
    1. as monotherapy
    2. in combination with dexamethasone
    3. in combination with pomalidomide + dexamethasone
    4. in combination with lenalidomide + dexamethasone

  2. Number of Participants Who Develop Anti-MOR03087 Antibodies [ Time Frame: during treatment period, maximum 3 years after 1st dose ]
    Number of participants who develop anti-MOR03087 antibodies, a measure of immunogenicity


Secondary Outcome Measures :
  1. Overall Response Rate [ Time Frame: maximum 3 years after 1st dose ]
    number (#) of patients responding (# stringent complete response + # complete response + # very good partial response + # partial response)

  2. Time to Progression [ Time Frame: patients were observed for up to 36 months ]
    Time to Progression (Kaplan Meier estimate)

  3. Progression-free Survival [ Time Frame: patients were observed up to 36 months ]
    Progression-free survival (Kaplan Meier estimates)

  4. Duration of Response [ Time Frame: patients were observed up to 36 months ]
    Duration of response (Kaplan Meier estimates)

  5. Pharmacokinetics: Cmax - Maximum Observed Serum Concentration for MOR202 [ Time Frame: up to 7 days after last MOR202 dose ]
    PK analysis for MOR202 4, 8 and 16 mg/kg IV once weekly dose groups only, since serum concentrations of MOR202 were substantially affected by target mediated drug disposition effects for remaining dose groups

  6. Pharmacokinetics: AUC Cycle 1+2 - Area Under the Time/Concentration Curve for MOR202 [ Time Frame: 56 days ]
    PK analysis for MOR202 4, 8 and 16 mg/kg IV once weekly dose groups only, since serum concentrations of MOR202 were substantially affected by target mediated drug disposition effects for remaining dose groups
