E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Among outpatients with recently diagnosed SARS-CoV-2 infection to compare the safety and efficacy of a single infusion of hyperimmune immunoglobulin (hIVIG) versus placebo, each given with standard of care (SOC), on clinical status after seven days. Two hypotheses will be tested to address this primary objective, which compares the primary endpoint among two study populations: 1) participants where a direct-acting antiviral (DAA) or other anti-SARS-CoV-2 agent was not prescribed as part of SOC treatment (stratum 1, see Section 6.1); and 2) all randomized participants (stratum 1 and stratum 2 combined). Stratum 2 is defined by prescribed treatments in SOC that include: DAA or other anti-SARS-CoV2 agents that are recommended for use by established national or international COVID-19 treatment guidelines. The hIVIG treatment will be considered superior to placebo if either of the two hypotheses are rejected. |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives, including subgroup analysis and safty outcomes, will be assesed for all randomised participants and for those in stratum 1 and stratum 2 separatly.
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Clinical risk based on age ≥ 55 years or an adult (age ≥ 18 years) with an immunosuppressed condition. 2. Positive test for SARS-CoV-2 within ≤5 days (if >1 test, the first positive is within ≤5 days). Tests may include an institutional-based nucleic acid amplification test (NAAT), or any protocol-approved rapid test. 3. Within ≤5 days from symptom onset, if symptomatic from current SARS-CoV-2 infection. 4. Agrees to not participate in another clinical trial for the treatment or management of SARS-CoV-2 infection through Day 7, or until hospitalized or significant disease progression if prior to Day 7 (defined by ordinal category 4 or 5). 5. Participant provides written informed consent prior to study procedures, and understands and agrees to adhere to planned study procedures through Day 28.
Information on which patient populations may benefit most from passive immune strategies targeting SARS-CoV-2 are limited. However, patients with impaired immune responses, whether from an underlying condition or the result of medical treatments, may have a delayed and/or reduced endogenous antibody response during COVID-19. Ongoing immunosuppressive condition or immunosuppressive treatment, includes: • Steroids equivalent to prednisone > 10 mg/day for at least the last 28 days • Rheumatologic or autoimmune disorder treated with a biologic or non-biologic immunosuppressive therapy • Antirejection medicine after solid organ or stem cell transplantation • Cancer treatment with systemic chemotherapy, biologic and/or cell-based therapy in the last 12 months • Primary or acquired severe B- or T-lymphocyte immune dysfunction • HIV infection • Splenectomy or functional asplenia
|
|
E.4 | Principal exclusion criteria |
1. Asymptomatic and had prior symptoms from the current infection that have now resolved (for >24 hours). 2. Asymptomatic and has received a vaccination for COVID-19 (≥1 dose). 3. Undergoing evaluation for possible admission to hospital for medical management (this does not include evaluation of possible hospitalization for public health purposes). 4. Evidence of pneumonia and/or hypoxia due to COVID-19 (NOTE: chest imaging is not required, but if available it should not show new infiltrates suggestive of pneumonia; hypoxia is defined by new oxygen supplementation or increase above pre-illness level). 5. Prior receipt of immunoglobulin product or passive immune therapy for SARS-CoV-2 in the past 90 days (i.e., convalescent plasma, SARS-CoV-2 monoclonal antibodies, or any IVIG). 6. Any of the following thrombotic or procoagulant conditions or disorders: • acute coronary syndrome, cerebrovascular syndrome, pulmonary embolism, or deep venous thrombosis within 28 days of randomization. • prothrombin gene mutation 20210, homozygous Factor V Leiden mutations, antiphospholipid syndrome, or a deficiency in antithrombin III, protein C, or protein S. 7. History of hypersensitivity to blood, plasma or IVIG excipients. 8. Known IgA deficiency or anti-IgA antibodies. 9. Medical conditions for which receipt of a 300 mL volume of IV fluid from study treatment may pose specific risk to the patient (e.g., decompensated congestive heart failure). 10. In the opinion of the investigator, any condition for which participation would not be in the best interest of the participant or that could prevent or confound protocol assessments.

E.5 End points |
E.5.1 | Primary end point(s) |
The goals of this study are to assess the safety and efficacy of a single infusion of hIVIG in preventing further progression related to COVID-19 when administered early after diagnosis and symptom onset (if symptomatic), with a further aim to concurrently assess for more rapid resolution of illness and restoration of health status to the pre-illness state. There is as yet no consensus on the optimal endpoint for determining clinical benefit from COVID-19 therapies in the ambulatory care setting, including the constituent elements of the endpoint and the timing of its assessment after a given treatment. The primary endpoint is the participant’s clinical status through Day 7, as defined by five mutually exclusive categories on an ordinal scale: 1. Asymptomatic and no limitations in usual activity due to COVID-19 2. Mild COVID-19 illness or minor limitations to usual activity 3. Moderate COVID-19 illness and major limitations to usual activity 4. Severe COVID-19 or other serious disease manifestation 5. Critical illness from COVID-19 or Death
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Day 7 was chosen for the timing of the primary endpoint for several reasons based on the following assumptions. The impact of hIVIG on disease progression may not be immediate; a few days may be needed to see the effects on clinical outcomes as measured by the ordinal outcome. Also, antibody differences between groups who receive passive immunotherapy versus those who do not are assumed to be greatest during the first week after infusion. Assessment of the ordinal outcome at a later time point may result in a diminished treatment difference because a greater proportion of participants may be transitioning through spontaneous recovery from COVID-19.
|
|
E.5.2 | Secondary end point(s) |
The clinical status as classified on the ordinal outcome scale will be assessed with a number of additional analyses comparing hIVIG (pooled for the 2 hIVIG products) with placebo, among the overall study population as well as for the key subgroup of those not receiving anti-SARS-CoV-2 monoclonal antibodies as part of SOC (stratum 1), including: 1. All-cause hospitalization or death through 28 days. 2. All-cause mortality through 28 days. 3. Significant disease progression through 28 days, using a time to event analysis with outcome defined by fulfilling criteria for category 4 or 5 on the ordinal scale. 4. Distribution of ordinal scale outcome at Day 4, 14, and 28. 5. The proportion of participants with any disease progression at Day 7, using a sliding dichotomous scale progression defined by a categorization on the ordinal scale that is worse than the status at entry. 6. The proportion of participants who progress to categories 3-5 on the clinical ordinal scale at Day 7 among participants in categories 1 or 2 of the ordinal scale at entry. 7. The severity of progression during follow-up, defined by the worst health status achieved on the clinical ordinal scale at any point by Day 7, 14, and 28. 8. The proportion of participants that attain their pre-COVID health status without limitations in usual activity (i.e., category 1) at Day 7, 14, and 28. 9. Change in quantitative measures of viral burden between Day 0 and Day 7, including serum antigen levels (e.g., nucleocapsid antigen) as well as by polymerase chain reaction (PCR) from nasal and saliva specimens. 10. Change in SARS-CoV-2 antibody levels between Day 0 and Day 7, including subclasses and neutralizing titers. 11. Utilization of health care resources through 28 days, defined by the proportion of participants that had health care engagement for the purposes of medical evaluation and/or management of COVID-19 illness (e.g., via telehealth, clinic, urgent care, emergency room, or hospitalization). 12. The severity of respiratory symptoms and dysfunction, as the worst status through 28 days, including: a) no respiratory symptoms, b) upper respiratory symptoms, c) lower respiratory symptoms without hypoxia, c) hypoxia requiring conventional oxygen supplementation by nasal canula, d) respiratory failure requiring high-flow oxygen delivery device or non-invasive ventilation, or e) respiratory failure requiring mechanical ventilation or extra-corporeal membrane oxygenation (ECMO). 13. Hypoxemia through Day 7, as evaluated through participant assessments of saturation of oxygen (SpO2) levels. Comparisons between groups will consider differences in SpO2 levels as well as explore the frequency of levels that drop below clinical thresholds (e.g., <94% and <90% on room air for those without COPD or use of supplemental O2 prior to COVID-19). 14. Proportion of patients starting other treatments targeting COVID-19. 15. Associations between changes in laboratory assessments from Day 0 to Day 7, and ordinal scale distribution and clinical outcomes over follow-up.
