Official Title
A Multicenter, Adaptive, Randomized Blinded Controlled Trial of the Safety and Efficacy of Investigational Therapeutics for the Treatment of COVID-19 in Hospitalized Adults (ACTT-3)
Brief Summary

ACTT-3 will evaluate the combination of interferon beta-1a and remdesivir compared to remdesivir alone. Subjects will be assessed daily while hospitalized. If the subjects are discharged from the hospital, they will have a study visit at Days 15, 22, and 29. For discharged subjects, it is preferred that the Day 15 and 29 visits are in person to obtain safety laboratory tests and oropharyngeal (OP) swab and blood (serum only) samples for secondary research as well as clinical outcome data. However, infection control or other restrictions may limit the ability of the subject to return to the clinic. In this case, these visits may be conducted by phone, and only clinical data will be obtained. The Day 22 visit does not have laboratory tests or collection of samples and is conducted by phone. The primary outcome is time to recovery by Day 29.

Detailed Description

This study is an adaptive randomized double-blind placebo-controlled trial to evaluate the
safety and efficacy of novel therapeutic agents in hospitalized adults diagnosed with
COVID-19. The study is a multicenter trial that will be conducted in up to approximately 100
sites globally. The study will compare different investigational therapeutic agents to a
control arm. New arms can be introduced according to scientific and public health needs.
There will be interim monitoring to allow early stopping for futility, efficacy, or safety.
If one therapy proves to be efficacious, then this treatment may become the control arm for
comparison(s) with new experimental treatment(s). Any such change would be accompanied by an
updated sample size. This adaptive platform is used to rapidly evaluate different
therapeutics in a population of those hospitalized with moderate to severe COVID-19. The
platform will provide a common framework sharing a similar population, design, endpoints, and
safety oversight. New stages with new therapeutics can be introduced. One independent Data
and Safety Monitoring Board (DSMB) will actively monitor interim data in all stages to make
recommendations about early study closure or changes to study arms.

ACTT-3 will evaluate the combination of interferon beta-1a and remdesivir compared to
remdesivir alone. Subjects will be assessed daily while hospitalized. If the subjects are
discharged from the hospital, they will have a study visit at Days 15, 22, and 29. For
discharged subjects, it is preferred that the Day 15 and 29 visits are in person to obtain
safety laboratory tests and oropharyngeal (OP) swab and blood (serum only) samples for
secondary research as well as clinical outcome data. However, infection control or other
restrictions may limit the ability of the subject to return to the clinic. In this case,
these visits may be conducted by phone, and only clinical data will be obtained. The Day 22
visit does not have laboratory tests or collection of samples and is conducted by phone.

All subjects will undergo a series of efficacy, safety, and laboratory assessments. Safety
laboratory tests and blood (serum and plasma) research samples and oropharyngeal (OP) swabs
will be obtained on Days 1 (prior to infusion) and Days 3, 5, 8, and 11 (while hospitalized).
OP swabs and blood (serum only) plus safety laboratory tests will be collected on Day 15 and
29 (if the subject attends an in-person visit or are still hospitalized).

The primary outcome is time to recovery by Day 29 for patients with baseline ordinal score 4,
5 and 6. A key secondary outcome evaluates treatment-related improvements in the 8-point
ordinal scale at Day 15. Each stage may prioritize different secondary endpoints for the
purpose of multiple comparison analyses.

COVID-19

Drug: Interferon beta-1a

Rebif (R) is a purified 166 amino acid human interferon beta glycoprotein with an amino acid sequence identical to natural fibroblast derived human interferon beta. Each 0.5 mL prefilled syringe contains 44 mcg of interferon beta-1a, 4 mg human albumin, USP; 27.3 mg mannitol, USP; 0.4 mg sodium acetate; and water for injection, USP.

Other: Placebo

The interferon beta-1a placebo contains either 0.5 mL 0.9% normal saline or 0.5 mL sterile water for injection.

Drug: Remdesivir

Drug Remdesivir is a single diastereomer monophosphoramidate prodrug designed for the intracellular delivery of a modified adenine nucleoside analog GS-441524. In addition to the active ingredient, the lyophilized formulation of Remdesivir contains the following inactive ingredients: water for injection, sulfobutylether beta-cyclodextrin sodium (SBECD), and hydrochloric acid and/or sodium hydroxide.

Eligibility Criteria

Inclusion Criteria:

1. Admitted to a hospital with symptoms suggestive of COVID-19.

2. Subject (or legally authorized representative) provides informed consent prior to
initiation of any study procedures.

3. Subject (or legally authorized representative) understands and agrees to comply with
planned study procedures.

4. Male or non-pregnant female adult > / = 18 years of age at time of enrollment.

5. Has laboratory-confirmed SARS-CoV-2 infection as determined by polymerase chain
reaction (PCR) or other commercial or public health assay in any respiratory specimen
or saliva, as documented by either of the following:

- PCR or other assay positive in sample collected < 72 hours prior to
randomization; OR

- PCR or other assay positive in sample collected >/= 72 hours but < 7 days prior
to randomization AND progressive disease suggestive of ongoing SARS-CoV-2
infection.

Note: if written documentation of the positive test result is not available at
enrollment (e.g., report from other institution), the subject may be enrolled but the
PCR should be repeated at the time of enrollment.

6. Illness of any duration, and at least one of the following:

- Radiographic infiltrates by imaging (chest x-ray, CT scan, etc.), OR

- SpO2 < / = 94% on room air, OR

7. Women of childbearing potential must agree to either abstinence or use at least one
primary form of contraception not including hormonal contraception from the time of
screening through Day 29.

8. Agrees to not participate in another clinical trial (both pharmacologic and other

admission.

4. Subjects with an estimated glomerular filtration rate (eGFR) < 30 mL/min are excluded
unless in the opinion of the PI, the potential benefit of receiving remdesivir
outweighs the potential risk of study participation.

5. Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) > 5 times the upper
limits of normal.
