Detection of Poor Mobilizer (PM) in Multiple Myeloma (MM) Patients

February 19, 2024 updated by: Fondazione EMN Italy Onlus

Detection of Poor Mobilizer (PM) in Multiple Myeloma (MM) Patients: Prospective Product Registry

The study is an italian multicentric and will be conducted in 20 centers. The aim of this study is to evaluate poor mobilizer (PM) rate in newly diagnosed MM patients who are mobilized with cyclophosphamide and G-CSF and plerixafor on demand.

Plerixafor is a specific reversible inhibitor of the chemokine receptor CXCR4 and prevents the binding of its ligand stromal cell derived factor SDF-1α also known as CXCL12, thereby releasing hematopoietic stem cells into the circulation.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

300 eligible patients ≥18 years old diagnosed with MM who are eligible to undergo treatment with an autologous haematopoietic stem cell transplant may be enrolled. Patients must meet all the inclusion criteria listed below within 7 days of first administration of cyclophosphamide in addition to signing an informed consent form.

A patient will be considered enrolled after he/she has met all eligibility criteria and has started the protocol treatment.

Exclusion Criteria:

  2. Non secretory MM
  3. Primary plasmacell leukemia.
  4. Age < 18.

  12. Left ventricular ejection fraction < 50%.
  13. Splenectomised or splenic irradiation.
  14. Psychiatric, addictive, or any disorder/disease which compromises ability to give truly informed consent for participation in this study and renders the patient at high risk from treatment complications or impairs the ability to comply with the study treatment and protocol.
  15. Treatment with G-CSF or other cytokine within 2 weeks prior to the first dose of G-CSF for mobilization.
  16. Patients previously treated with Plerixafor

Poor Mobilizer (PM) in Multiple Myeloma (MM) patients
Drug: Plerixafor
Plerixafor (AMD3100) is a selective, reversible inhibitor of the receptor chemokine (C-X-C motif) receptor 4 (CXCR4) and prevents binding of its cognate ligand stromal cell derived factor-1α (SDF-1α), also known as chemokine (C-X-C motif) ligand 12 (CXCL12) [3]. CXCR4 is a co-receptor, along with CD4, for the binding of human immunodeficiency virus, type 1 (HIV-1) to its receptor cells.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Assessment of success rate expressed as % of patients mobilizing ≥2x106 CD34+ cells/kg in maximum 3 apheresis and patient who achieves the optimal target of 4x106 CD34+ cells/kg up to 5 apheresis.
Time Frame: 3 years
3 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
% of patients having received plerixafor in the study population
Time Frame: 3 years
3 years
Evaluate in patients failing mobilisation how many of them received plerixafor and how many did not
Time Frame: 3 years
3 years
Evaluation of speed of mobilization using plerixafor, in terms of increase in number of circulating CD34+ cells from time 0 to 6-11 hours after the first dose of plerixafor.
Time Frame: 3 years
3 years
Total number of CD34+ cells collected per apheresis day
Time Frame: 3 years
3 years
Confirmation of factors predicting a poor mobilization: patients who experienced grade 3-4 haematological toxicity during induction, used lenalidomide as induction treatment, aged > 60 years old and experienced cytopenia at diagnosis.
Time Frame: 3 years
