Inclusion Criteria:
Patients will be eligible for the study if they meet all of the following criteria:
1. Histologically or cytologically confirmed diagnosis of multiple myeloma that is relapsed or relapsed-and-refractory after at least 2 or more prior lines of therapy.
i. Patients must have achieved a best response of at least minor response (MR) to at least one prior line of therapy;
ii. Quantitative immunoglobulin levels may be substituted for M-protein levels (if not available) only for the purposes of inclusion criteria pertaining to responses/progression on past lines of therapy
2. Progressive disease, as defined in International myeloma working group uniform response criteria for multiple myeloma, must have occurred either during or subsequent to the patient?s last treatment for multiple myeloma prior to the current enrollment;
3. Measurable disease defined by serum M-protein ≥1 g/dL, or urine light chain ≥200 mg/24 hours, or abnormal serum FLC ratio with involved FLC > 10 mg/dL provided serum FLC ratio is abnormal. The serum free light chain assay is applicable only to those patients with oligosecretory myeloma who do not produce sufficient M-protein to be measurable by standard SPEP and UPEP techniques. Such oligosecretory patients may be able to qualify for study enrollment on the basis of the free light chain assay
4. Age >18 years;
5. Eastern Cooperative Oncology Group (ECOG; performance status of ≤2;
6. Life expectancy ≥12 weeks;
7. Signed written informed consent per institutional and federal regulatory requirements;
8. Did not receive chemotherapy (including systemic steroids), immunotherapy (interferon), Imids (thalidomide/lenalidomide), proteasome inhibitors (bortezomib), or radiotherapy for at least 21 days prior to Day 1 of Cycle 1;
9. Did not receive any investigational treatment for at least 28 days prior to study entry;
10. Absolute granulocyte count of ≥1,000/μL, platelet count ≥50,000/μL, and hemoglobin ≥8.0 g/dL, with no transfusion within the preceding 7 days;
11. Adequate liver function defined by a bilirubin value ≤2 times the upper limit of normal (ULN), and transaminases (AST and ALT) values ≤2.5 times ULN;
12. Adequate renal function defined by a creatinine clearance of ≥30 mL/min;
13. Adequate cardiac function defined by a left ventricular ejection fraction (LVEF) ≥40%, QTc <450 msec, and no evidence of clinically significant dysrhythmias on ECG;
14. Patient must have substantially recovered from clinically significant toxicities from prior therapies for multiple myeloma such that, in the judgment of the investigator, the residual toxicity will not likely pose an undue safety risk to the subject and will not likely confuse the interpretation of adverse events occurring in this trial.; and
15. Fertile men and women must agree to use a medically effective contraception method from signing of informed consent until 30 days after the final dose of study medication. Premenopausal women of reproductive capacity and women less than 24 months post menopause must have a negative serum pregnancy test documented prior to study entry.
Exclusion Criteria:
Patients meeting any of the following criteria will not be eligible for participation in the study:
1. Patients who never achieved a best response of at least minor response (MR) to at least one prior line of therapy;
2. Clinical spinal cord compression syndromes (unless patient has undergone treatment, for example, surgery or radiation therapy, and neurological findings are ≤ Grade 1 and patient is off corticosteroids for spinal cord edema or on a stable regimen of < 10 mg/day prednisone equivalent;
3. Clinical signs of brain involvement or leptomeningeal disease;
4. Plasma cell leukemia (plasma cells > 2000/cubic mm);
5. Women who are pregnant or breast feeding;
6. Other serious illness or medical condition(s) including, but not limited to the following:
i. Congestive heart failure or angina pectoris, even if medically controlled. Previous history of myocardial infarction within 1 year of study entry, uncontrolled hypertension (defined as systolic BP >160 mmHg, diastolic BP >100 mmHg), or arrhythmias,
ii. Active infection, including HIV, hepatitis B, or hepatitis C infection;
iii. History of psychosis, unless corticosteroid-induced with complete resolution following discontinuation or reduction in steroid dosing ;
iv. Subcortical brain damage; or
v. Current dialysis therapy;
7. Hypersensitivity to fluphenazine or other phenothiazines;
8. Currently being treated with hematopoietic growth factors other than erythropoietin (EPO). Treatment with hematopoietic growth factors may be started during the study with development, or worsening, of cytopenia;
9. Concurrent use of anticholinergics
10. Concurrent use of phenothiazine and atypical antipsychotics;
11. Concurrent use of anti-seizure drugs, with the exception of gabapentin for treatment of neuropathy;
12. Grade 2 or higher persisting prior treatment-related neuropathy
13. Concurrent use of systemic steroids with the exception of chronically administered steroids equivalent to ≤ 10 mg/day prednisone if patient has been on this therapy for ≥1month.
14. History of seizures or extrapyramidal symptoms; or
History of other malignancies within the past 3 years, other than adequately treated non-melanoma skin cancer, or in situ carcinoma of the cervix, unless the other malignanacy is quiescent and medical monitor approval is obtained
