An additional bone marrow biopsy will be required if the prior bone marrow is deemed unsuitable for analysis by the Sponsor. 10.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. 11.

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 days following administration of the last dose of study drug. 14. Able to comprehend and give informed consent 15.

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). 4.Positive hepatitis panel (including hepatitis B surface antigen and/or hepatitis C virus antibody) prior to or at Screening 5.Positive human immunodeficiency virus (HIV) antibody at Screening 6.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 7.Concurrent treatment with corticosteroids other than a stable daily dose equivalent to = 10 mg/day prednisone for previous 3 months 8.Erythropoietin deficiency. Concurrent treatment with erythropoietin is permitted if the patient has been on a stable dose for the previous 3 months. 9.Concurrent usage of iron supplementation unless the patient has been on a stable dose for at least 4 weeks. 10.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 11.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 12.Females who are pregnant, lactating, or, if having reproductive potential, are considered potentially unreliable with respect to contraceptive practice. 13. History of hypersensitivity to BIVV009 or any of its components.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Part A: The primary objective of Part A is to determine whether BIVV009 administration results in a = 2 g/dL increase in hemoglobin (Hgb) levels or increases Hgb to = 12 g/dL and obviates the need for blood transfusion during treatment in patients with primary CAgD who have a recent history of transfusion Part B: The primary objective of Part B is to evaluate the long-term safety and tolerability of BIVV009 in patients with primary CAgD.;Secondary Objective: Part A: Efficacy: •To assess the effect of BIVV009 on clinical events and laboratory parameters related to hemolysis and anemia in patients with primary CAgD •To assess the effect of BIVV009 on quality of life (QOL) in patients with primary CAgD Safety: •To evaluate the overall safety and tolerability of BIVV009 in patients with primary CAgD Exploratory: •To assess the effect of BIVV009 on specific complications of CAgD •To evaluate the effect of BIVV009 on certain disease-related biomarkers in patients with primary CAgD •To evaluate the pharmacokinetics of BIVV009 Part B: •The secondary objective of Part B is to investigate the durability of response during long-term treatment with BIVV009 in patients with primary CAgD.;Primary end point(s): The primary efficacy endpoint is the responder rate. A patient will be considered a responder if he or she did not receive a blood transfusion from Week 5 through Week 26 (EOT) and did not receive treatment for CAgD beyond what is permitted per protocol. Additionally, the patient’s Hgb level must meet either of the following criteria: • Hgb level is = 12 g/dL at the treatment assessment endpoint (defined as mean value from Weeks 23, 25, and 26), or • Hgb increased = 2 g/dL from baseline (defined as the last Hgb value before administration of the first dose of study drug) at treatment assessment endpoint;Timepoint(s) of evaluation of this end point: Week 26 (EOT) | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): •Mean change from baseline in bilirubin (excluding patients with Gilbert’s Syndrome) at the treatment assessment endpoint (mean of values at Week 23, 25, and 26) •Mean change from baseline in QOL, as assessed by the change in Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue scale scores at the treatment assessment endpoint •Mean change from baseline in lactate dehydrogenase (LDH) at the treatment assessment endpoint •Number of transfusions and number of units after the first 5 weeks of study drug administration •Mean change from baseline in Hgb at the treatment assessment endpoint ;Timepoint(s) of evaluation of this end point: Week 26 (EOT) | — |
