Inclusion criteria

  • Known diagnosis of symptomatic multiple myeloma.
  • At least 2 prior lines of therapies which must include treatment with at least 1 of an immunomodulatory drug (IMiD) or a proteasome inhibitor (PI). The patients must have received an IMiD or a PI for ≥2 cycles or ≥2 months of treatment.
  • Patients must have been responsive to at least 1 prior line of therapy (minimal response or better).
  • Refractory to the most recently received IMiD or PI included therapy (ie, patients must have progressed during or within 60 days of completion of treatment with IMiD or PI). For patients who have received more than 1 type of IMiD or PI, their disease must be refractory to the most recent one.
  • Measurable disease defined as at least 1 of the following:

    • Serum M-protein ≥0.5 g/dL (≥5 g/L);
    • Urine M-protein ≥200 mg/24 hours.
  • Written informed consent.

Exclusion criteria

Exclusion criteria:

  • \<18 years old.
  • Eastern Cooperative Oncology Group (ECOG) performance status >2.
  • Life expectancy of less than 3 months.
  • Pretreated with any anticluster of differentiation (CD) 38 agent.
  • Concurrent plasma cell leukemia.
  • Known amyloidosis.
  • Disease measurable only by serum free light chain (FLC) analysis.

What researchers measure

Primary outcomes

  1. Assessment of PK: Cmax

    To evaluate the maximum observed concentration (Cmax)

    Time frame: Cycle 1, up to 168 hours after start of infusion

  2. Assessment of PK: tmax

    To evaluate the time to reach Cmax (tmax)

    Time frame: Cycle 1, up to 168 hours after start of infusion

  3. Assessment of PK: AUC0-168h

    To evaluate area under the plasma concentration versus time curve over the dosing interval (AUC0-168h)

    Time frame: Cycle 1, up to 168 hours after start of infusion

  4. Assessment of PK: Ceoi

    To evaluate the concentration observed at the end of an IV infusion (Ceoi)

    Time frame: Cycle 1 Day 1, Cycle 2 Day 1, Cycle 4 Day 1; Cycle duration is 28 days

  5. Assessment of PK: Ctrough

    To evaluate concentration observed just before investigational medicinal product (IMP) administration during repeated dosing (Ctrough)

    Time frame: Up to approximately 40 weeks (Cycle 10)

Secondary outcomes

  1. Adverse Events

    Treatment Emergent Adverse Events (TEAEs)/Serious Adverse Events (SAE) based on standard and systematic assessment including infusion associated reactions (IARs), laboratory test abnormalities, vital signs and ECOG performance status

    Time frame: Up to 30 days after the last IMP administration

  2. Anti-tumor activity: Overall response (ORR)

    Proportion of patients achieving: stringent complete response (sCR), complete response (CR), very good partial response (VGPR), or partial response (PR) according to International Myeloma Working Group (IMWG 2016) criteria

    Time frame: Up to 12 months after last patient treated

  3. Anti-Tumor Activity: Duration of response (DOR)

    Time from the date of the first determined response to the date of subsequent determined progressive disease or death, whichever happens earlier

    Time frame: Up to 12 months after last patient treated

  4. Anti-Tumor Activity: Time to progression (TTP)

    Time interval from the date of first IMP administration to the date of the first assessed disease progression using IMWG criteria

    Time frame: Up to 12 months after last patient treated

  5. Anti-Tumor Activity: Progression free survival (PFS)

    Time interval from the date of first IMP administration to the date of the first documentation of disease progression or death due to any cause, whichever comes first

    Time frame: Up to 12 months after last patient treated

  6. Anti-Tumor Activity: Overall survival (OS)

    Time interval from the date of first IMP administration to death due to any cause

    Time frame: Up to 12 months after last patient treated

  7. Immunogenicity

    To evaluate the presence of antidrug antibodies (ADA) to isatuximab

    Time frame: Up to 13 months (10 cycles + 3 months) after last patient treated
