About

Multiple myeloma (MM) is a neoplastic expansion of bone marrow plasma cells. Despite advances in treatment in recent years, MM is still a fatal disease. MM is characterized by the ability of malignant cells to produce large amounts of monoclonal immunoglobulin. The secretion of these immunoglobulins can be detected as the "M-protein" in serum, and the measurement of the M-component is used both for diagnosis and to evaluate treatment response and relapse. The high load of secreted proteins in MM cells requires a efficient way to clear these proteins from the cells and targeting protein degradation is an important therapeutic target in MM. This is today done by inhibiting the proteasome, one of the two central ways cells can degrade proteins, by drugs named proteasome inhibitors (including bortezomib, ixazomib and carfilzomib). Patients become resistant to these drugs, and it is therefore likely that myeloma cells also utilise another important system for protein degradation, called autophagy. Pre-clinical studies have shown that the combination of the proteasome inhibitor carfilzomib and the autophagy inhibitor hydroxychloroquine increases myeloma cell death and that hydroxychloroquine is able to reverse MM cell resistance to carfilzomib. This is the rationale for this study, where the investigators add the autophagy inhibitor hydroxychloroquine to a standard regime of carfilzomib and dexamethasone, to determine a maximum tolerated dose of this combination and to study tolerability.

Inclusion criteria

Demographic and diagnosis

A prior diagnosis of multiple myeloma according to International Myeloma Working Group (IMWG) criteria with documented disease progression in need of treatment at time of screening.
- Must meet all of the following criteria:
Patients must have received at least two prior therapies including bortezomib and an immunomodulatory agent (may include autologous bone marrow transplantation)
Patients must not be refractory to carfilzomib
Relapsed or progressive disease documented according to IMWG criteria
Patients must have evaluable multiple myeloma with at least one of the following (assessed within 21 days prior to registration)
Serum M-protein ≥ 10 g/L, or
Urine M-protein ≥ 200 mg/24 hours
Involved serum immunoglobulin free light chain (SFLC) > 100 mg/L AND abnormal kappa/lambda ratio
Eastern Cooperative Oncology Group (ECOG) performance status 0-2
Life expectancy ≥ 6 months

Laboratory:

Absolute neutrophil count ≥ 1.0 x 109/L
Hemoglobin ≥ 7 g/dL (with or without transfusion support)
Platelets ≥ 50 x 109/L (with or without transfusion support)
Total bilirubin ≤ 2 x upper limit of normal (ULN)
Aspartate amino transferase/alanine amino transferase ratio (ASAT/ALAT) ≤ 2.5 x ULN

Concurrent conditions

Left ventricular ejection fraction (LVEF) ≥ 40 % determined by 2D transthoracic echocardiogram (ECHO) or Multigated Acquisition Scan (MUGA)
No baseline peripheral neuropathy ≥ grade 2
No history of allergic reactions to compounds of similar chemical or biological composition to carfilzomib, dexamethasone or hydroxychloroquine, including Captisol (a cyclodextrin derivate used to solubilize carfilzomib)
No macular degeneration or retinopathy (diabetic or otherwise) as examined during screening, or known porphyria or psoriasis (with the exception of early dry age-related macular degeneration or minor microhemorrhages in the retinal periphery)
Well-controlled psoriasis allowed under care of a specialist who agrees to monitor the patient for exacerbations
No other condition that would require therapy with hydroxychloroquine, including but not limited to, any of the following:

Patients with a prior malignancy treated with chemotherapy, biologic agents, and/or radiation are eligible for this study if they have completed therapy ≥ 2 years previously with no evidence of recurrent disease
Patients with a prior malignancy treated with surgery alone are eligible for this study if they have completed therapy ≥ 2 years previously with no evidence of recurrent disease
No uncontrolled intercurrent illness including, but not limited to, any of the following:

Unstable angina pectoris
Myocardial infarction within 6 months of enrollment
Cardiac arrhythmia
Clinically significant pericardial disease
Cardiac amyloidosis

At least 14 days since prior antimyeloma agents, not including carfilzomib/dexamethasone
Concurrent therapy with bisphosphonates allowed at the discretion of the treating physician
Concurrent hematopoetic growth factors allowed, including filgrastim granulocyte colony-stimulating factor (G-CSF) or pegfilgrastim, epoetin alpha, and darbepoetin alpha
Concurrent participation in non-treatment studies allowed, if it will not interfere with participation in this study
No concurrent radiotherapy except local radiotherapy during the treatment phase of this study for palliation of pain or prevention of fracture
No concurrent treatment with a different investigational regimen
No concurrent treatment with other anticancer agents
No concurrent participation in other investigational trials that involve novel therapies

Ethical/other

Male patients must use an effective barrier method of contraception during study and for 3 months following the last dose if sexually active with a FCBP.
Ability to understand and willingness to sign the informed consent document
Signed informed consent and expected cooperation of the patients for the treatment and follow up must be obtained and documented according to International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use - Good Clinical Practice (ICH-GCP), and national/local regulations.

Exclusion criteria

Not meeting inclusion criteria
Female patients who are pregnant or lactating.
Any reason why, in the opinion of the investigator, the patient should not participate (e.g. not able to comply with study procedures, including being unable to perform full ophthalmologic examination).
