Cardiac: involvement is defined as the presence of a mean left ventricular wall thickness on echocardiogram more than 12 mm in the absence of a history of hypertension or valvular heart disease, or unexplained low voltage (\< 0.5 mV) on electrocardiogram; or an NT-proBNP \> 332 ng/L in CKD 1 or 2 patients or a BNP \> 100ng/L in those who are CKD3.~ 3.

Autonomic or peripheral neuropathy: based on clinical history, autonomic dysfunction with orthostasis, symptoms of nausea or dysgeusia, gastric atony by gastric emptying scan, diarrhea or constipation, or abnormal sensory and/or motor findings on neurologic examination.~* AL Amyloidosis Cardiac Risk stage I, II or IIIa disease. Staging system defined by: NT-proBNP cut off of \< 332 pg/mL and troponin I cut-off of \< 0.10 ng/mL as thresholds for stages I, II and III; NT-proBNP \< 8500 for stage IIIa.~  1. Stage I, both under threshold;~ 2. Stage II, either troponin or NT-proBNP \[but not both\] over threshold;~ 3. Stage III, both over threshold;~ 4. Stage IIIa, both over threshold but NT-proBNP \< 8500 pg/ml.~* Clinical laboratory values as specified below before the first dose of study drug:~  1. Echocardiographic ejection fraction \> 45% within 28 days before the first dose of study drug.~ 2. Within the 3 days of the first dose of study drug: i. Platelet count \> 75 x 109/L; ii. Neutrophil count \> 1.0 x 109/L; iii. Total bilirubin \< 2 x ULN; iv. Alkaline phosphatase \< 5 x ULN; v. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) \< 3 x ULN; vi. eGFR \> 30 mL/min/1.73 m2~* Female patients who are postmenopausal for at least 1 year before the screening visit, OR are surgically sterile, OR, if they are of childbearing potential, agree to practice 2 effective methods of contraception, at the same time, from the time of signing the informed consent through 30 days after the last dose of study drug, or agree to completely abstain from heterosexual intercourse.~* Male patients, even if surgically sterilized (ie, status post vasectomy), who agree to practice effective barrier contraception during the entire study treatment period and through 30 days after the last dose of study drug, OR agree to completely abstain from heterosexual intercourse.~* Voluntary written consent must be given before performance of any study-related procedure not part of standard medical care with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care.~Exclusion Criteria:~* Treatment with any investigational products within 28 days before the first dose of study drug.~* Requirement for other concomitant chemotherapy, immunotherapy, radiotherapy, or any ancillary therapy considered to be investigational.~* Failure to have fully recovered (ie, \> Grade 1 toxicity) from the effects of prior chemotherapy regardless of the interval since last treatment.~* Active fungal infection requiring continued therapy.~* Cardiac system:~  1. QTc \> 470 milliseconds (msec) on a 12 lead ECG obtained during the Screening period. If a machine reading is above this value, the ECG should be reviewed by a qualified reader and confirmed on a subsequent ECG.~ 2. AL Amyloidosis Risk Stage IIIb disease. Stage IIIb is defined by NT-proBNP \> 8500 pg/mL and troponin I \> 0.10 ng/mL.~ 3. New York Heart Association (NYHA) classification III or IV.~ 4. Enzyme-documented myocardial infarction within 6 months before enrollment.~ 5. Chronic atrial fibrillation.~ 6. Grade 2 or 3 atrioventricular (AV) block (Mobitz, Type I permitted).~ 7. Supine systolic blood pressure \< 90 mmHg, or symptomatic orthostatic hypotension, or a decrease in systolic blood pressure on standing of \> 20 mm Hg in spite of being treated for orthostatic hypotension.~ 8. History of a bleeding diathesis or currently receiving treatment with warfarin. Patients are allowed to take aspirin.~* GI system:~  1. Severe diarrhea (= Grade 3) not controllable with medication (such as octreotide) or requires administration of total parenteral nutrition.~ 2. Known GI disease or GI procedure that could interfere with the oral absorption or tolerance of study drug, including difficulty swallowing.~* Neurologic/ Social system:~  1. Patients with \> Grade 2 peripheral neuropathy or painful peripheral neuropathy on clinical examination will be excluded.~ 2. Previous or ongoing psychiatric illness.~ 3. Social situations that would limit compliance with study requirements.~* Systemic infections:~  1. Known to be human immunodeficiency virus (HIV)-positive.~ 2. Known to be hepatitis B surface antigen-positive or has known active hepatitis C infection.~ 3. Uncontrolled infection requiring systemic antibiotics.~* Clinically overt multiple myeloma (bone marrow plasma cells \> 30%) and bone lesions or hypercalcemia.~* Patients with non-AL amyloidosis.~* Presence of uncontrolled autoimmune hemolytic anemia or thrombocytopenia, or of active malignancy with the exception of non-melanoma skin cancer, cervical cancer, treated early-stage prostate cancer provided that prostate-specific antigen is within normal limit, or any completely resected carcinoma in situ.~* Female patients who are lactating or pregnant.~* Major surgery within 14 days before the first dose of study drug.~* Patients who are taking and are required to take any of the following agents that are CYP3A inhibitors: Amiodarone, Erythromycin, Fluconazole, Itraconazole, Ketoconazole, Miconazole, Diltiazem, Verapamil, Amprenavir, Fosamprenavir, Clarithromycin, Telithromycin, Nefazodone, Atazanavir, Darunavir, Indinavir, Lopinavir, Nelfinavir, Ritonavir, Saquinavir, Tipranavir.
