Eligibility
Key inclusion criteria
1. Completed the End of Study Visit in Study NEOD001-201
2. Adequate bone marrow reserve, hepatic and renal function, as demonstrated by:

* Absolute neutrophil count (ANC) =1.0 × 109/L
* Platelet count =75 × 109/L
* Hemoglobin =9 g/dL
* Total bilirubin =2 × upper limit of normal (ULN)
* Aspartate aminotransferase (AST) =3 × ULN
* Alanine aminotransferase (ALT) =3 × ULN
* Alkaline phosphatase (ALP) =5 × ULN (except for subjects with hepatomegaly and isozymes specific to liver, rather than bone)
* Estimated glomerular filtration rate (eGFR) =25 mL/min/1.73 m2 as estimated by the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation, or measured GFR =25 mL/min/1.73 m2
3. Systolic blood pressure 80-180 mmHg
4. Women of childbearing potential must have a negative pregnancy test during Screening and must agree to use highly effective physician-approved contraception from Screening to 90 days following the last study drug administration
5. Male subjects must be surgically sterile or must agree to use highly effective physician-approved contraception from Screening to 90 days following the last study drug administration
6. Ability to understand and willingness to sign an informed consent form prior to initiation of any study procedures
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Any new medical contraindication or clinically significant abnormality on physical, neurological, laboratory, vital signs, or electrocardiographic (ECG) examination (e.g., atrial fibrillation; with the exception of subjects for whom the ventricular rate is controlled) that precludes continuation or initiation of treatment with NEOD001 or participation in the study
2. Symptomatic orthostatic hypotension that in the medical judgment of the Investigator would interfere with subject's ability to safely receive treatment or complete study assessments
3. Myocardial infarction, uncontrolled angina, uncontrolled ventricular arrhythmias, or ECG evidence of acute ischemia, within 6 months prior to the Month 1-Day 1 Visit
4. Severe valvular stenosis (e.g., aortic or mitral stenosis with a valve area <1.0 cm2) or severe congenital heart disease
5. ECG evidence of acute ischemia or active conduction system abnormalities with the exception of any of the following:

* First degree atrioventricular (AV) block
* Second degree AV block Type 1 (Mobitz Type 1/ Wenckebach type)
* Right or left bundle branch block
* Atrial fibrillation with a controlled ventricular rate (uncontrolled [i.e., >110 bpm] ventricular rate is not allowed [determined by an average of three beats in Lead II or 3 representative beats if Lead II is not representative of the overall ECG])
6. Has not recovered (i.e., equivalent to a Common Terminology Criteria for Adverse Events [CTCAE] =Grade 2) from the clinically significant toxic effects of prior anticancer therapy. Exception: subjects who have received treatment with a proteasome inhibitor such as bortezomib may have CTCAE Grade 2 neuropathy.
7. Received any of the following within the specified time frame prior to the Month 1-Day 1 Visit:

* Oral or IV antibiotics, antifungals, or antivirals within 1 week, with the exception of prophylactic oral agents. Note: In the event that a subject requires the chronic use of antivirals, Medical Monitor permission is required for entry into the study.
* Hematopoietic growth factors, transfusions of blood or blood products within 1 week
* Chemotherapy, radiotherapy, HDAC inhibitors, or other plasma cell directed therapy within 2 weeks
* ASCT within 4 weeks (i.e., ASCT is allowed if it occurred before enrollment in Study NEOD001-201 or after completion of Study NEOD001-201 if it was at least 4 weeks before Month 1-Day 1 of this study)
* Major surgery within 4 weeks (or within 2 weeks following consultation with and approval of Medical Monitor)
* Planned organ transplant during the study
* Any investigational agent, other than NEOD001, within 4 weeks
* Any experimental imaging agent directed at amyloid within 2 weeks
8. Active malignancy with the exception of any of the following:

* Adequately treated basal cell carcinoma, squamous cell carcinoma, or in situ cervical cancer
* Adequately treated Stage I cancer from which the subject is currently in remission and has been in remission for =2 years
* Low-risk prostate cancer with Gleason score <7 and prostate-specific antigen <10 mg/mL
* Any other cancer from which the subject has been disease-free for =2 years
9. History of Grade =3 infusion-related adverse events (AEs) or hypersensitivity to NEOD001
10. History of severe allergy to any of the components of NEOD001 such as histidine/L-Histidine, Trehalose, or Polysorbate 20
11. Currently known uncontrolled bacterial, viral, fungal, HIV, hepatitis B, or hepatitis C infection
12. Women who are breastfeeding
13. Any condition which could interfere with, or the treatment for which might interfere with, the conduct of the study or which would, in the opinion of the Investigator, unacceptably increase the subject's risk by participating in the study
14. Unable or unwilling to adhere to the study-specified procedures and restrictions
15. Subject is under legal custodianship
