About this study

Official title: Phase Ib of Cyclophosphamide, Pomalidomide, Dexamethasone and Daratumumab (CPD-DARA) in Patients With Relapsed/Refractory Multiple Myeloma. (The CPD-DARA Study)

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.

Read the 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
  3. 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.
  4. 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.
  5. Time to Response. Exploratory Objectives
  6. To assess effect of CPD-DARA treatment on patient-reported outcomes and quality of life.
  7. Efficacy according to the IMWG (International Myeloma Working Group) in High Risk vs Standard Risk patients.
  8. Disease Control Rate (DCR). Exploratory Endpoints
  9. 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.
  10. 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.
  11. Disease Control Rate (DCR) defined as stable disease or better.

  • CyclophosphamideDrug

    Cyclophosphamide will be administered PO at 50mg daily for all cohorts in the study.

  • PomalidomideDrug

    Also called Pomalyst, Imnovid

    Pomalidomide will be administered PO on days 1-21 of each 28 day cycle. The dose will be specified by the dose level to which the patient has been enrolled.

  • DexamethasoneDrug

    Dexamethasone will be administered PO at 40mg on days 1, 8, 15 and 22 of each 28 day cycle.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Daratumumab, Cyclophosphamide and Pomalidomide in people with Multiple Myeloma, run by Cancer Trials Ireland at 3 sites in Ireland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 39 inclusion and 31 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 13 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Ireland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of DLT within the first cycle of CPD in combination with DARA at each dose level. (time frame: Up to cycle 1). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04667663.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Apr 2026.
