This study is designed to evaluate three dose levels of Anti-SARS-CoV-2 Immunoglobulin Intravenous (Human) (COVID-HIGIV) for safety and pharmacokinetics (PK) in healthy adults. Twenty-eight healthy adult subjects will be enrolled into the study to receive a single dose of COVID-HIGIV or placebo with 84 days of safety and PK follow-up post-administration.
This study will be a Phase 1, single-center, randomized, double-blind, placebo-controlled
design to assess safety and PK of COVID-HIGIV in healthy adults.
In total, 28 healthy adult subjects are to be enrolled and randomized 2:2:2:1 into four study
treatment arms to receive a single intravenous (IV) infusion of one of three COVID-HIGIV dose
levels or saline placebo, respectively.
The enrollment/dosing of the first seven subjects in the study will be staggered. Available
safety data will be reviewed by Study Monitoring Committee (SMC) after seven subjects have
completed at least 72 hours of safety follow-up. Subjects will be followed up for safety and
PK up to 84 days post-administration.
The SMC will perform overall ongoing review of safety data during the study.
Biological: COVID-HIGIV
COVID-HIGIV is a purified immunoglobulin G (IgG) liquid preparation containing antibodies (including neutralizing antibodies) to SARS-CoV-2. COVID-HIGIV will be administered via intravenous infusion.
Other Name: NP-028
Other: Placebo (saline)
The reference product is a liquid solution of normal saline (0.9% weight per unit volume (w/v) sodium chloride). Placebo will be administered via intravenous infusion.
Inclusion Criteria:
1. Able and willing to provide written informed consent (voluntarily signed by the
subject) prior to performing study procedures.
2. Females and males 18-60 years of age, inclusive.
3. Have a body mass index (BMI) less than or equal to 35.0 kg/m2.
4. Women who are either:
A) Not of childbearing potential: either surgically sterile (at least six weeks post
bilateral tubal ligation, bilateral oophorectomy or hysterectomy); or post-menopausal
(defined as ≥50 years of age with a history of ≥12 months without menses prior to
randomization in the absence of other pathologic or physiologic causes, following
cessation of exogenous sex-hormonal treatment); OR
B) Women of childbearing potential (WOCBP) who are not planning to be pregnant during
the study period and meet all of the following criteria:
Negative serum pregnancy test (PT) at Screening; and Negative PT prior to dosing at
Day 1; and
Use of a highly effective contraception during the study period:
- Hormonal contraceptives (e.g., implants, pills, patches) initiated ≥30 days prior
to Day 1; or
- Intrauterine device (IUD) inserted ≥30 days prior to Day 1; or
- Double barrier type of birth control (e.g., male condom with female diaphragm,
male condom with cervical cap).
5. Subject understands and agrees to comply with planned study procedures.
6. Healthy as determined by the Principal Investigator based on medical history, physical
exam, vital signs, urinalysis, blood chemistry and hematology test results at
Screening and evidence of no prior exposure to SARS-CoV-2 (i.e., Reverse transcription
polymerase chain reaction [RT-PCR] negative for SARS-CoV-2 and negative for SARS-CoV-2
antibodies) at Screening.
Exclusion Criteria:
1. Use of any investigational product, within 30 days prior to Screening, or use of
investigational SARS-CoV-2 vaccines, SARS-CoV-2 monoclonal antibodies or COVID-19
convalescent plasma at any time prior to Screening or during the study follow-up
period, or subject plans to participate in another clinical study during the study
period.
2. Screening clinical laboratory test result greater than the laboratory's upper limit of
normal (ULN) for alanine aminotransferase (ALT), aspartate aminotransferase (AST),
random glucose, total and/or bilirubin, blood urea nitrogen (BUN), or creatinine.
Other serum chemistry parameters that are not within the reference range will not be
considered exclusionary unless deemed clinically significant by the Principal
Investigator.
3. History of allergy or hypersensitivity to blood or plasma products or to COVID-HIGIV
excipients (proline, PS80).
4. History of allergy to latex or rubber.
5. History of hemolytic anemia.
6. History of Immunoglobulin A (IgA) deficiency.
7. Receipt of any blood product within the past 12 months.
8. Plasma donation within 7 days or significant blood loss or blood donation within 56
days of randomization/dosing.
9. History of known congenital or acquired immunodeficiency or receipt of
immunosuppressive therapy (e.g., prednisone or equivalent for more than two
consecutive weeks within the past three months).
10. History of thrombosis or hypercoagulable state with increased risk of thrombosis.
11. History of clinically significant chronic illness (e.g., requiring hospitalization in
the past three months) such as cardiac, pulmonary, renal, hepatic or other chronic
conditions.
12. Receipt of a live vaccine within 28 days prior to screening or anticipated receipt of
a live vaccine during the study period.
13. Currently pregnant, breastfeeding, or planning to become pregnant during the study.
14. History of, or suspected substance abuse problem (including alcohol).
15. Other medical condition which may place subject at increased risk due to participation
in the study as determined by the investigator.
16. Any planned elective surgery during the study period.
17. An opinion of the investigator that it would be unwise to allow the individual to be
randomized into the study.
