Background and study aims
Multiple myeloma is a type of bone marrow cancer. The disease is called refractory myeloma if the cancer no longer responds to treatment. If the cancer returns after treatment, it is called relapsed myeloma. Pomalidomide and dexamethasone are used as a standard treatment for patients with multiple myeloma. The new treatment being tested in this study is pomalidomide and dexamethasone with the addition of cyclophosphamide, to see if it is effective in treating patients with Relapsed and Refractory Multiple Myeloma (RRMM). A study of 250 patients is to be carried out to compare the combination of pomalidomide, cyclophosphamide and dexamethasone with pomalidomide and dexamethasone alone in patients with relapsed/refractory multiple myeloma. This study will also collect bone marrow and blood samples to study the mechanism of action of the drug and to identify markers that may be able to predict response to treatment.

Who can participate?
To enter the study patients must have received treatment with proteasome inhibitor and lenalidomide previously and have relapsed or be refractory to this treatment.

What does the study involve?
Patients are randomly allocated to receive treatment with either Pd (pomalidomide and dexamethasone) or CPD (pomalidomide, cyclophosphamide and dexamethasone) and continue treatment until disease progression or until they are unable to tolerate treatment any longer. Treatment is given for 21 days of a 28-day cycle with at least monthly visits to hospital. Bone marrow and blood samples are compulsory for the trial and are taken at the beginning, during and at the end of treatment.

What are the possible benefits and risks of participating?
The participant will be receiving a treatment that is available through normal care pathways and is known to be effective in some patients in the treatment of myeloma. Additional blood samples will be needed and therefore possibly more needle punctures will be required to take these samples. Potential side effects of the treatment will differ from patient to patient but treatment modifications and supportive care will be given to minimise any effects.

Where is the study run from?
The study is being run by the University of Leeds and is part of the Myeloma UK portfolio of myeloma trials. The trial will be run from 15 of the Myeloma UK Network NHS sites in the UK. Treatment will be given at the NHS site.

When is the study starting and how long is it expected to run for?
September 2015 to September 2017.

Who is funding the study?
University of Leeds (UK).

Who is the main contact?

Scientific titlePomalidomide Specific Targeting in Relapsed and Refractory Myeloma (MUK Seven)
Study acronymMUK Seven
Study objectivesCurrent hypothesis as of 08/09/2015:
1. To compare the combination of pomalidomide, cyclophosphamide and dexamethasone with pomalidomide and dexamethasone alone.
2. Identify markers from bone marrow and blood samples to predict response to pomalidomide.

Previous hypothesis:
1. To present further safety and efficacy data of pomalidomide in relapsed/refractory myeloma in the UK.
2. Identify markers from bone marrow and blood samples to predict response to pomalidomide.

On 08/09/2015 the following changes were made to the trial record:
1. The study design was changed from 'Interventional non-randomised single arm trial' to 'Interventional randomised trial'.
2. The overall trial start date was changed from 01/08/2014 to 01/09/2015.
3. The overall trial end date was changed from 01/02/2016 to 01/09/2017.

Health condition(s) or problem(s) studiedRelapsed multiple myeloma or refractory multiple myeloma
InterventionCurrent interventions as of 08/09/2015:
Patients will be randomised to receive treatment with either Pd (pomalidomide and dexamethasone) or CPD (pomalidomide, cyclophosphamide and dexamethasone). All treatment cycles will consist of 28 days and participants will receive treatment with pomalidomide and dexamethasone until they progress or are unable to tolerate treatment any longer.

Previous interventions:
Participants will receive treatment with oral pomalidomide and dexamethasone, this will be given to the participant to take at home. 4 mg of Pomalidomide will be taken daily on days 1-21 of the 28 day cycle, 40 mg of dexamethasone will be taken on days 1, 8, 15 and 22 only. The participant will see their doctor at hospital at least once a month.

Participants will receive treatment with pomalidomide and dexamethasone until they progress or are unable to tolerate treatment any longer.

Primary outcome measureCurrent primary outcome measures as of 08/09/2015:
Progression free survival, from randomisation until disease progression

Previous primary outcome measures:
Safety and toxicity, as assessed by adverse reactions throughout the trial
Secondary outcome measuresCurrent secondary outcome measures as of 08/09/2015:
1. Response to treatment defined as achieving at least a partial response during treatment. Maximal response will be defined as the proportion of participants achieving a response as their maximum response to treatment. Time to response will be measured from randomisation to the maximal response achieved. Duration of response will be from the time of achieving at least a partial response until disease progression.
2. Safety and toxicity, as assessed by adverse reaction throughout the trial.

Previous secondary outcome measures:
1. Response to treatment defined as achieving at least a partial response during treatment. Maximal response will be defined as the proportion of participants achieving a response as their maximum response to treatment. Time to response will be measured from registration to the maximal response achieved. Duration of response will be from the time of achieving at least a partial response until disease progression.
2. Progression-free survival will be calculated from registration until disease progression or death. Overall survival will be calculated from registration to death.
