E.3 | Principal inclusion criteria |
* For healthy adult subjects:
- signed informed consent form
- Male or female subjects as determined by no clinically significant deviation from normal in medical history and physical examination
- ages 18 to 45
* For pediatric patients:
- Parent or legally acceptable representatives must sign informed consent form for all subjects < 18 years old. Assent should be obtained when the minor is judged to be of an age of reason (see protocol Appendix 1).
- signed informed consent form from the mother donating the umbilical cord blood.
- Male and female subjects as determined by no clinically significant findings in medical history or physical examination that would prevent the subjects from donating 1-9 mL of blood. |

a) Any significant acute or chronic medical illness.
b) Any major surgery within 4 weeks of enrollment

k) PMH of positive blood screen for hepatitis C antibody, hepatitis B surface antigen, or HIV viral RNA or HIV-1, -2 antibody.
(2) Physical Findings
a) Evidence of excessive bruising, petechia, or organ dysfunction or clinically significant findings that would prevent donation of blood.
(3) Prohibited Treatments and/or Therapies
a) Exposure to any investigational drug or placebo within 4 weeks of enrollment.
b) Use of any other drugs, including over-the-counter medications and herbal preparations, within 1 week prior to study enrollment.

if they test positive on an antibody test, but they are confirmed not HIV, HCV, or HBV infected after been tested according to standard of care guidelines.
d) Subjects with cancer on any therapy or subjects in remission treated with chemotherapy < 3 months ago.
e) Subjects with known genetic disorders such as hemophilia or thrombophilia or other factor deficiencies.

n) History of a significant complicated pregnancy as determined by PI or designee (for women donating umbilical cord blood).
o) Pediatric subjects <1 year of age with maternal history of lupus anticoagulant, ITP, or other acquired coagulopathy.
(2) Physical Findings
a) Evidence of excessive bruising, petechia, or organ dysfunction or clinically significant findings that would prevent donation of blood.
b) For neonates, birth weight < 2500gm
