Multiple Myeloma
Conditions
Brief summary
To determine whether a combination of four novel agents bortezomib(Velcade), lenalidomide (Revlimid), Daratumumab (Darzalex) & dexamethasone in combination with low-dose cyclophosphamide is sufficiently active in a high risk population of myeloma patients, to take forward into a phase III trial compared to standard treatment.
Detailed description
Multiple myeloma (MM) is a plasma cell tumour with an annual incidence in the UK of approximately 40 -50 per million i.e. 4500 new cases per annum. Approximately 20% of the patients diagnosed with multiple myeloma have a significantly worse prognosis at 3 years than other multiple myeloma patients and these are characterised as having high risk (HR) disease defined by genetic lesions and gene expression profiles (GEP). There have been no significant improvements in outcome over the last decade for patients with HR disease. Therefore, it is important to identify more effective treatment options for this group of patients especially given that the number of novel agents are potentially available and which can be given as part of intensive therapy regimen. Intensive treatment in HR patients has been used outside the UK with promising results but access to drugs in the UK has been challenging with constraints in the NHS treatment pathway. This is the first time in the UK that newly diagnosed multiple myeloma patients may be entered into a clinical trial prospectively according to their genetic risk profile. It provides a unique opportunity to improve outcomes and provide evidence for high cost novel treatment strategies in this restricted population of poor prognosis patients. The MUKnine trial is designed to evaluate the novel treatment strategies for multiple myeloma patients with HR disease and incorporate a genetic screening component. Patients identified as having HR disease are then invited to take part in the phase II single arm, multi centre trial that investigates the intensive treatment schedule comprising four novel agents bortezomib (Velcade), lenalidomide (Revlimid), daratumumab (Daralex), dexamethasone with cyclophosphamide. The trial will determine if this treatment strategy is sufficiently active to take forward in to further testing in this population. Patients identified as not having HR disease will receive standard local treatment and will be followed up in a cohort study to assess response, progression free survival and overall survival.
