Inclusion Criteria

All patients must meet all the following inclusion criteria to be enrolled:
1.Adult male and female patients = 18 years of age at Screening
2.Body weight of = 39 kg at Screening
3.Confirmed diagnosis of primary CAgD based on the following criteria:
a.Chronic hemolysis
b.Polyspecific direct antiglobulin test (DAT) positive
c.Monospecific DAT strongly positive for C3d
d.Cold agglutinin titer = 64 at 4¿C
e.IgG DAT = 1+, and
f.No overt malignant disease
4.Hemoglobin level = 10.0 g/dL
5.Bilirubin level above the normal reference range, including patients with Gilbert’s Syndrome
6.Ferritin levels above the lower limit of normal. Concurrent treatment with iron supplementation is permitted if the patient has been on a stable dose during the previous 4 weeks.
7.Presence of one or more of the following CAgD-related signs or symptoms within 3 months of Screening:
a.Symptomatic anemia defined as:
i.Fatigue
ii.Weakness
iii.Shortness of breath
iv.Palpitations, fast heart beat
v.Light headedness, and/or
vi.Chest pain
b.Acrocyanosis
c.Raynaud’s syndrome
d.Hemoglobinuria
e.Disabling circulatory symptoms, and/or
f.Major adverse vascular event (including thrombosis)
8.Bone marrow biopsy within 6 months of Screening with no overt evidence of lymphoproliferative disease or other hematological malignancy. An additional bone marrow biopsy will be required if the prior bone marrow is deemed unsuitable for analysis by the Sponsor.
9.Documented vaccinations against encapsulated bacterial pathogens (Neisseria meningitis, including serogroup B meningococcus where available, Haemophilus influenzae, and Streptococcus pneumoniae) within 5 years of enrollment or as specified in Section 6.1.1.1
10.Patients must be willing to receive transfusions if they meet the eligibility criteria during the study treatment period. Patients who do not have a recent history of transfusion due to patient refusal or patient decision should not be enrolled if they do not agree to receive blood transfusions as needed.
11.Adequate IV access
12.If female, must be post-menopausal, surgically sterile, or be established on (= 3 months prior to Screening) and agree to continue to use the same highly effective methods of birth control throughout the study and for 9 weeks following administration of the last dose of study drug
13.Males must be surgically sterile for at least 90 days or when sexually active with female partners of child-bearing potential will agree to use highly effective contraception from Day 0 until 9 weeks following administration of the last dose of study drug.
14.Able to comprehend and give informed consent
15.Able to comply with the requirements of the study and to complete the full sequence of protocol-related procedures
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 4
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range 36

Exclusion Criteria

Patients who meet any of the following criteria will be excluded from the study:
1.Cold agglutinin syndrome secondary to infection, rheumatologic disease, or active hematologic malignancy
2.History of blood transfusion within 6 months of screening, or history of more than one blood transfusion within 12 months of screening
3.Clinically relevant infection of any kind within the month preceding enrollment (eg, active hepatitis C, pneumonia)
4.Clinical diagnosis of systemic lupus erythematosus (SLE); or other autoimmune disorders with anti-nuclear antibodies at Screening. Anti-nuclear antibodies of long standing duration without associated clinical symptoms will be adjudicated on a case-by-case basis during the Confirmatory Review of Patient Eligibility (Section 6.1.1.3).
5.Positive hepatitis panel (including hepatitis B surface antigen and/or hepatitis C virus antibody) prior to or at Screening
6.Positive human immunodeficiency virus (HIV) antibody at Screening
7.Treatment with rituximab monotherapy within 3 months or rituximab combination therapies (eg, with bendamustine, fludarabine, ibrutinib, or cytotoxic drugs) within 6 months prior to enrollment
8.Concurrent treatment with corticosteroids other than a stable daily dose equivalent to
= 10 mg/day prednisone for previous 3 months
9.Erythropoietin deficiency. Concurrent treatment with erythropoietin is permitted if the patient has been on a stable dose for the previous 3 months.
10.Concurrent usage of iron supplementation unless the patient has been on a stable dose for at least 4 weeks.
11.Clinically significant medical history or ongoing chronic illness that would jeopardize the safety of the patient or compromise the quality of the data derived from his/her participation in this study (as determined by the Investigator [or designee]) at Screening
12.Concurrent treatment with other experimental drugs or participation in another clinical trial with any investigational drug within 30 days or 5 half lives, whichever is greater, prior to treatment start
13.Females who are pregnant, lactating, or, if having reproductive potential, are considered potentially unreliable with respect to contraceptive practice
14.History of hypersensitivity to BIVV009 or any of its components.
