Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is determining whether the addition of cyclophosphamide to pomalidomide and dexamethasone improves progression free survival in patients with relapsed refractory myeloma (RRMM) compare to pomalidomide and dexamethasone alone. Patients will be randomised on a 1:1 basis to receive CPD or Pd. Treatment will be continued until disease progression or unacceptable toxicity.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Multiple myeloma is the second most common hematologic malignancy in the European Union (EU), responsible for an estimated 21,000 deaths in the EU in 2008. For patients that relapse or are refractory to current standard treatment (combination of bortezomib/lenalidomide, dexamethasone and an alkylating agent) there are few options available and therefore the prognosis within this group is often poor with response to treatment decreasing with successive relapses until resistant disease develops. . Current standard treatment at first relapse in the UK is the use of bortezomib in combination with dexamethasone and cyclophosphamide. Another common treatment is lenalidomide given with dexamethasone and cyclophosphamide. The addition of cyclophosphamide has demonstrated to improve treatment outcomes whilst being tolerated well. A recent clinical study has shown the addition of cyclophosphamide to the combination of pomalidomide and dexamethasone has shown to be safe and tolerable and beneficial in terms of treatment outcomes. The primary aim of this study is to investigate whether the addition of cyclophosphamide to pomalidomide and dexamethasone leads to an improved progression free survival. A secondary aim is to identify markers from clinical material that will predict response to pomalidomide in a group of relapsed and refractory multiple myeloma (RRMM) patients to provide important information for use in discussions with NICE on how best to improve the value and use of pomalidomide in the UK in the RRMM setting.

* All participants must have failed treatment with either lenalidomide and proteasome inhibitor in one of the following ways:

1. Documented progressive disease on or within 60 days of completing treatment with lenalidomide and/or proteasome inhibitor ; or
2. In case of prior response \[≥ partial response (PR)\] to lenalidomide or proteasome inhibitor, participants must have relapsed within 6 months after stopping treatment with lenalidomide and/or proteasome inhibitor containing regimens; or
3. Participants who have not had a ≥ minimal response (MR) despite receiving at least 4 cycles of treatment or who have developed intolerance/toxicity after a minimum of two cycles of lenalidomide and/or proteasome inhibitor containing regimen

1. As part of a stem cell transplant; or
2. A minimum of 4 consecutive cycles of an alkylator based therapy; or
3. Progression on treatment with an alkylator; provided that the participant received at least 2 cycles of an alkylator containing therapy.
* Life expectancy of at least 3 months
* Eastern Cooperative Oncology Group (ECOG) performance status score of 0, 1, or 2
* Required laboratory values within 14 days of treatment:

* Able to give informed consent and willing to follow trial protocol
* Aged over 18 or over
* Females of childbearing potential (FCBP) must agree to utilise one reliable form of contraception for 28 days prior to starting trial treatment, during the trial, and for 28 days after trial treatment discontinuation and even in the case of dose interruption and must agree to regular pregnancy testing during this timeframe
* Females must agree to abstain from breastfeeding during trial participation and 28 days after trial drug discontinuation
* Males must agree to use a latex condom during any sexual contact with FCBP during the trial, including during any dose interruptions and for 28 days following discontinuation from this trial even if he has undergone a successful vasectomy
* Males must also agree to refrain from donating semen or sperm while on pomalidomide, including during any dose interruptions and for 28 days after discontinuation from this trial
* All participants must agree to refrain from donation blood while on trial drug, including during dose interruptions and for 28 days after discontinuation from this trial

Exclusion Criteria

1. Uncontrolled congestive heart failure
2. Myocardial infarction within 12 months prior to starting trial treatment
3. Unstable or poorly controlled angina pectoris, including Prinzmetal variant angina pectoris.
