E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To investigate the pharmacokinetics of AZD7442 in immunosuppressed patients with no or suboptimal vaccine response. |
|
E.2.2 | Secondary objectives of the trial |
To assess safety and efficacy of AZD7442 to induce protective immunity against SARS-CoV-2 in immunosuppressed patients as well as investigate PK interactions with immunosuppressive drugs. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Kidney transplant recipients on immunosuppressive therapy. • Patients with their last SARS-CoV-2 vaccination at least 3 weeks prior to inclusion. • Patients with no or impaired humoral immune response (SARS-CoV-2 Spike RBD antibody level <2000 BAU/mL) at least 3 weeks after the last dose of SARS-CoV-2 vaccine. • Not participating in therapeutical intervention studies, within the last 30 days. • Adult patients (≥18 years). |
|
E.4 | Principal exclusion criteria |
• Women who are breastfeeding, pregnant patients or women of childbearing potential (WOCBP) not on highly effective contraception (not acceptable methods: progesterone-only oral hormonal contraception, male/female condom without spermicide or cap, diaphragm or sponge with spermicide). • Sensitivity or intolerance to any study drug excipients. • Acute febrile illness or acute infection. • Prior receipt of any monoclonal antibodies or convalescence plasma against COVID19 (licensed or investigational) < 6 months before enrolment. • Administration of immunoglobulins ≤90 days before enrolment. • Allergic reaction to previous administrations of monoclonal antibodies. • Triple anticoagulation therapy. • Bleeding disorder (e.g. factor deficiency, coagulopathy or platelet disorder), or prior history of significant bleeding or bruising following IM injections or venipuncture. • Received any vaccination against other infectious diseases within the last four weeks prior to study drug administration. • Blood drawn in excess of a total of 450 mL (1 unit) for any reason within 30 days prior to randomization. • Patients that the doctor considers to be unsuitable due to, for example, mental condition or abuse. |

E.5 End points |
E.5.1 | Primary end point(s) |
AZD 7442 serum concentrations (µg/mL). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Concentrations measured pre-dose (and 10-60 minutes after end of IV-infusion) and then weekly the first month and then after 3 and 6 months (pre-dose), or before the second dose if it is given before 6 months, after each dose. In addition, a 9- and 12-month samples is also to be obtained following the last dose in the study for all patients. |
|
E.5.2 | Secondary end point(s) |
1. Absolute intramuscular bioavailability of AZD7442 2. Local and systemic adverse events. 3. Neutralizing capacity of patient serum samples 4. Number of patients with AZD7442 serum levels <19.9 μg/mL +IgG1 SARS-CoV-spike protein antibodies. 5. SARS-CoV-2 infection assessed by anamnestic patient history (including positive PCR test) 6. Severe COVID-19 caused by SARS-CoV-2 variants of concern (VOC), characterized by a minimum of either pneumonia or hypoxemia and a WHO Clinical Progression Scale Score of 5 or higher 7. Hospitalization or death from COVID-19 8. Acute rejection episodes. 9. Cellular immune response to SARS-CoV-2 VOC. 10. Humoral and cellular immune response to additional SARS-CoV-2 vaccination in patients on AZD7442 treatment (additional vaccination is not a study intervention, response rates will be compared to patients not receiving AZD7442 [results from the CEPI study]). 11. Pharmacokinetic interactions with immunosuppressive drugs based on 3-point AUC estimations.
