Clinical Trial Summary

The purpose of this study is to evaluate the safety (including tolerability), pharmacokinetics, pharmacodynamics and clinical activity of BSYX-A110 administered in a 3-dose regimen on Study Days 0, 7, and 14.

Description:

This Phase II study will be a randomized, double blind, placebo controlled study of BSYX-A110 in very low birth weight neonates. A total of 80 infants will be dosed in this study. Participants will receive either BSYX-A110 or placebo, at 60 mg/kg or 90 mg/kg. The Study Drug will be administered at 48-120 hours of life, 7 days after the initial dose, and 14 days after the initial dose for all dose groups.

Eligibility

Inclusion Criteria:

Patients must meet all of the following criteria at the time of first infusion (Day 0):

1. 48-120 hours of age, inclusive

2. Birth weight of 700-1300 grams

3. Inpatient in a Neonatal Intensive Care Unit

Exclusion Criteria:

Patients may have none of the following at the first dose:

1. Survival not expected for at least 1 week after infusion

2. Clinically overt systemic infection, as determined by history, physical examination, and positive culture from a normally sterile site. (Infuse only when infant clinically stable and cultures negative for 48 hours. If being evaluated for sepsis, decision to infuse may be deferred as allowed by protocol infusion window. Infusions outside of protocol window must be approved by Sponsor.)

3. Severe congenital anomalies or genetic disorders that are likely to be fatal or that may interfere with drug distribution or metabolism, as determined by history and/or physical examination, and including but not limited to:

i. Trisomy 13 ii. Trisomy 18 iii. Hypoplastic Left Heart Syndrome iv. Omphalocele v. Gastroschesis vi. Holoprosencephaly

4. Known or suspected hepatic or renal insufficiency

5. Clinically uncontrolled seizures

6. Immunodeficiency other than due to prematurity

7. A history of standard immune globulin administration prior to first study drug infusion (excluding Hepatitis B Immune Globulin, HBIG)

8. Any history, in the infant subject or its mother, of a hypersensitivity or severe vasomotor reaction to immunoglobulin G, or blood products

9. Currently receiving, recently received, or planned to receive other investigational agents that could interfere with conduct or results of this study; including enrollment in another investigational study for a product under an IRB-approved protocol

10. Expectation that the patient will not be able to be followed for the duration of the study

11. Mother with serology positive for hepatitis B surface antigen
