Brief Summary:

This study is a Phase Ib, open label, single arm, adaptive multi-centre clinical study. The target population for this study are patients with relapsed/refractory multiple myeloma (MM). Patients will have a confirmed diagnosis of MM, with measurable disease as per IMWG criteria, in the second relapse and beyond (third line of therapy and beyond). Patients will need to have exposure to lenalidomide and a proteasome inhibitor. Patients will be treated with Cyclophosphamide-Pomalidomide-Dexamethasone (CPD) in combination with daratumumab (DARA) to determine the Maximum Tolerated Dose (MTD), Dose Limiting Toxicity (DLT) and Recommended Phase II Dose (RP2D) of the combination.

Pomalidomide will be administered orally at three dose levels 4, 3 and 2mg on days 1-21 of each 28-day cycle. Treatment will be repeated on day 1 of a 28-day cycle until disease progression, unacceptable toxicity, withdrawal of consent, physician's decision, or sponsor's decision to terminate the study, whichever occurs first.

Condition or disease Intervention/treatment Phase
Multiple Myeloma Drug: Daratumumab Drug: Cyclophosphamide Drug: Pomalidomide Drug: Dexamethasone Phase 1

Detailed Description:

Primary Objective 1. To determine the MTD and RP2D for pomalidomide that can safely be administered with DARA and cyclophosphamide.

Primary Endpoint

1. To determine the incidence of DLT within the first cycle of CPD in combination with DARA at each dose level.

Secondary Objectives

  1. To evaluate the safety and tolerability of the CPD-DARA regimen.
  2. To evaluate efficacy measures. Secondary Endpoints

1. Safety will be assessed by standard clinical and laboratory tests (haematology, serum chemistry). Adverse events grade will be defined by the NCI CTCAE (National Cancer Institute Common Terminology Criteria for Adverse Events) version 5.0.

2. The following efficacy endpoints will be measured: i. Complete Response (CR) rate after six cycles of CPD-DARA and at the end of study treatment.

ii. Best Overall Response. iii. Minimal Residual Disease (MRD) negative rate after six cycles of CPD-DARA. iv. Progression Free Survival (PFS) and Overall Survival (OS) at 6 months and 2 years.

v. Time to Response. Exploratory Objectives

  1. To assess effect of CPD-DARA treatment on patient-reported outcomes and quality of life.
  2. Efficacy according to the IMWG (International Myeloma Working Group) in High Risk vs Standard Risk patients.
  3. Disease Control Rate (DCR). Exploratory Endpoints

1. To assess effect of CPD-DARA treatment on patient-reported outcomes and quality of life, as assessed by the FACT-G and MyPOS questionnaires completed at study commencement, at every cycle of study treatment and at completion of the study treatment.

2. Efficacy according to the IMWG in High Risk (defined by ISS stage 3 and/or high-risk cytogenetic findings including t(4;14), t(14;16), and del17p) vs Standard Risk patients.

3. Disease Control Rate (DCR) defined as stable disease or better.

    • Monoclonal plasma cells in the bone marrow ≥ 10% or presence of a biopsy proven plasmacytoma AND
    • Measurable disease as defined by any of the following:
    • IgG multiple myeloma: serum monoclonal paraprotein (M-protein) level ≥ 1.0 g/dl or urine M-protein level ≥ 200mg/24 hours;
    • IgA, IgE, IgD or IgM multiple myeloma: serum M-protein level ≥ 0.5g/dl or urine M-protein level ≥ 200mg/24 hours;
