Brief Summary

This study will evaluate if the combination of Pomalidomide, Cyclophosphamide and Prednisone is safe and provides benefits in patients with multiple myeloma relapsed and/or refractory to lenalidomide.

Conditions

Multiple Myeloma

Keywords

Pomalidomide; Relapsed/Refractory to Lenalidomide

Outcome Measures

Primary Outcomes (1)

• PCP safety and efficacy

  We aim to identify the maximum tolerated dose (MTD) of Pomalidomide delivered in combination with Cyclophosphamide and Prednisone, defined as the dose that achieves a dose-limiting toxicity (DLT) in 25% of patients. The efficacy will be assessed by evaluating the very good partial response (VGPR) rate following the proposed regimen.

Secondary Outcomes (5)

• Overall survival

  3 years

• Progression-free survival

  3 years

• Time-to-progression

  3 years

• Time to next therapy

• Tumor response and survival in particular subgroups of patients

Induction This multicenter phase I followed by a phase II trial will evaluate the safety and efficacy of the combination Pomalidomide-Cyclophosphamide-Prednisone (PCP) in patients (pts) with MM relapsed/refractory to lenalidomide. In the phase I we assess the maximum tolerated dose (MTD) of PCP in 25% of pts. The first 4 pts are given the second dose level, accrual continues with 4 pts per dose level for a maximum of 24 pts. The dose level associated with an updated DLT is recommended for the next patient cohort. Each patient is assigned to a salvage therapy including Cyclophosphamide and Prednisone (both 50 mg every other d), and Pomalidomide at one of the following doses:1 mg/d;1.5 mg/d;2 mg/d;2.5 mg/d In the phase II a total of 43 pts will be treated with the MTD of PCP. Pts enrolled at the MTD during the phase I will be included in the Phase II trial. Maintenance (each cycle repeated every 28 d, until PD) Pomalidomide: 2.5 mg/d; Prednisone: 25 mg every other d

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Age ≥ 18 years.
• Patient with multiple myeloma who received 1 to 3 lines of treatment (including high-dose chemotherapy with stem cell support, conventional poli-chemotherapy, thalidomide- , bortezomib- and melphalan-based regimens) and is relapsed or relapsed and refractory (that means relapsed while on salvage or progression within 60 days of most recent therapy) to lenalidomide therapy.
• Patient has clinical relapse of MM based on standard criteria.
• Patient has measurable disease, defined as follows:
• For secretory multiple myeloma, measurable disease is defined as any quantifiable serum monoclonal protein value (greater than 1 g/dL of IgG M-protein, greater than 0.5 g/dL of IgA M-protein or IgD M-protein OR urine light-chain excretion of more than 200 mg/24 hours)
• For oligo- or non-secretory multiple myeloma, measurable disease is defined by the presence of measurable soft tissue (not bone) plasmacytomas as determined by clinical examination or applicable radiographs (i.e., MRI, CT scan).
• A measurable lesion is defined as a lesion with minimum largest diameter of \>20 mm (if measured by conventional techniques such as physical exam, conventional CT scan, MRI) or of \>10 mm (if measured by spiral CT scan) in one dimension.
• Patient has a Karnofsky performance status ≥ 60%.

You may not qualify if:

• Any serious medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from signing the informed consent form.
• Pregnant or breast feeding females.
• Any condition, including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study.
• Use of any other concomitant standard/experimental anti-myeloma drug or therapy.
• Uncontrolled or severe cardiovascular disease including myocardial infarction within 6 months of enrolment, New York Heart Association (NYHA) Class III or IV heart failure, uncontrolled angina, clinically significant pericardial disease, or cardiac amyloidosis Other malignancy within the past 5 years. Exceptions: basal cell or non metastatic squamous cell carcinoma of the skin, cervical carcinoma in situ or FIGO Stage 1 carcinoma of the cervix.
• Concurrent medical condition or disease (e.g., active systemic infection, uncontrolled diabetes, pulmonary disease, cardiac disease) that is likely to interfere with study procedures or results, or that in the opinion of the investigator would constitute a hazard for participating in this study.
