Study type
Description of intervention(s) / exposure
The intervention will be Montelukast given at a dose of 20mg or 40mg per day orally with Gemfibrozil 600mg twice daily orally. The dose of Montelukast will start at 20mg and increase to 40mg if there is no toxicity at the 7 day review. The increased dose will be given until seven days after all subsequent chemotherapy cycles are administered. The study drugs will be given daily without interruption until seven days after the last chemotherapy agent is administered.. The dose can be reduced back to 20 mg a day if any significant side effects are observed.
Chemotherapy (CyBorD.) Montelukast and Gemfibrozil is given from day 1 until day 28 of each cycle and 7 days after all chemotherapy planned is administered. The dose is increased from 20mg to 40mg if there is no toxicity at 7 days. It can be reduced back to 20mg if any subsequent toxicity is observed.
28 day cycle in all patients.
Bortezomib 1.3mg^m2 subcutaneous injection on day 1,7,15,21 of each 21 day cycle. for two cycles
Cyclophosphamide 100mg given orally daily throughout treatment period for two cycles
Dexamethasone 20mg orally is given on d1,d7,d14,d21 of each 28 day cycle for two cycles
Intervention code [1] 295680 0
Treatment: Drugs
Comparator / control treatment
The patient will act as there own control. The response will be compared to the patients previous historical lack of response to standard CyBorD chemotherapy at the end of two cycles.(

This will enable analysis using a paired t test.
Control group

Primary outcome [1] 299360 0
Change in either Serum M protein or serum light chain after two cycles of treatment with Montelukast and Gemfibrozil by analysis of pathology results.

2 cycles of therapy
Primary outcome [2] 303717 0
Unexpected side effects will be determined by WHO criteria.
This will be assessed weekly by history and examination.
Blood tests will be performed and reviewed weekly for unexpected Renal, Hepatic or Haematological toxicity

12 months from treatment by analysis of patient records.

Key inclusion criteria
Patients with progressive disease after at least 8 weeks of treatment with a standard accepted Multiple Myeloma regimen, who have exhausted all other therapies. Patients will have to have response data for their previous treatment with Velcade/Cyclophosphamide/Dexamethasone.

Patients who show less than partial response at 8 weeks of Bortezomib/Cyclophosphamide/Dexamethasone chemotherapy. This is 20% of patients.
Minimum age
18 Years
Maximum age
80 Years
Both males and females
Can healthy volunteers participate?
Key exclusion criteria
Patient showing at least a partial response to last treatment regimen for multiple myeloma. Pregnancy.
ECOG status 3 or 4
Patients unable to give informed consent.

Study design
Purpose of the study
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?

Intervention assignment
Single group
Other design features
Patients results will be compared to their previous response/results to same chemotherapy regimen. The analysis will be with paired t-test for the values of paraprotein, light chain and percentage bone marrow involvement. Due to the design of the study only a small number of patients will be needed to demonstrate efficacy. If their is no demonstrable improvement in response after analysis of these 6 patients then the treatment would have deemed to fai and no other research will take place.
Phase 2 / Phase 3
Type of endpoint(s)
Statistical methods / analysis
Paraprotein, serum light chain and will be converted to a percentage of pre treatment level. it will then be analysed using paired t-test with the patients previous results acting as control.

Brief summary
This pilot study aims to test whether Montelukast and Gemfibrozil when added to CyBorD chemotherapy (Bortezomib Cyclophosphamide and Dexamethasone 28 day cycle) induces responses in patients not responding to this chemotherapy.

Who is it for?
You may be eligible to join this study if you are aged 18-80 years with progressive multiple myeloma after at least 8 weeks (two cycles) of treatment with a standard Bortezomib/Cyclophosphamide/Dexamethasone chemotherapy.

Study details
A total of 6 patients will be enrolled prior to a decision to expand or shut down the trial, depending on toxicity and response. Participants will receive further two cycles of CyBorD chemotherapy regimen with the addition of Montelukast. and Gemfibrozil..

Patients will be able to continue Montelukast and Gemfibrozil following completion if a response is observed depending on side effects

The hypothesis is that Montelukast which is an extremely well tolerated medication used to treat Asthma in all age groups, will sensitize patient’s tumour to chemotherapy which was previously shown to be resistant to the same therapy.
