MAD0004J08: Study to Evaluate the Safety and Concentrations of Monoclonal Antibody Against Virus That Causes COVID-19 Disease.
Study Details
Study Description
Brief Summary
A Phase I dose-escalation study to test a new monoclonal antibody (called MAD0004J08) against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19 disease. The study aims to evaluate the safety and pharmacokinetics (distribution and elimination) of anti-SARSCoV-2 monoclonal antibody in healthy adults.
The primary objective of the study is to evaluate the safety of anti-SARSCoV-2 monoclonal antibody (that is the appearance of adverse events), the pharmacokinetics (how MAD0004J08 is distributed and eliminated by human body), the generation of anti-drug antibodies (ADAs) (that is the possible production of antibodies against the drug, which could invalidate it efficacy) and finally the ability of MAD0004J08 to neutralize SARSCoV-2. Furthermore a blood sample would be used to evaluate a kit (DIESSE kit), developed by Toscana Life Sciences, able to detect the administered drug. This kit is not used to evaluate study paramethers.
30 subjects, that should respect the Inclusion/Exclusion criteria, will be enrolled.
About 12 visits will be performed during the study, study duration will be about 6 months.
Subjects will be distributed into 3 Cohorts, each of them divided into 2 groups that would receive MAD0004J08 (Dose 1 = 48 mg, Dose 2 = 100 mg or Dose 3 = 400 mg) or placebo. Administration occurs as intramuscular injection (single injection for Cohort 1 and Cohort 2 and, two injections for Cohort 3) .

Detailed Description
A Phase I dose-escalation study to evaluate the safety and pharmacokinetics of anti-SARSCoV- 2 monoclonal antibody MAD0004J08 in healthy adults.
Two Italian clinical sites are involved in the study. It is a first-in-human, single-dose, dose-escalation, double-blind, placebo-controlled, randomised, safety and pharmacokinetics study.
Three single ascending doses (48 mg, 100 mg and 400 mg) and placebo will be administered by intramuscular injection to three study cohorts (10 subjects/cohort) as single doses, in the morning of day 1.
There are 5 sentinel subjects for each Cohort, they will be treated one at the time at 48 h distance (after evaluation of any possible treatment related adverse event).
Active treatment and placebo will be assigned within each cohort and group according to the study randomisation list.
Go/No-go decision on escalation from Cohort 1 to Cohort 2 and from Cohort 2 to Cohort 3 will be taken after evaluation of Cohort 1/Cohort 2 safety data up to 48 h post-dose by an independent Data Safety Monitoring Board.
The primary objective of the study is to evaluate the safety of three single dose levels of MAD0004J08 in healthy subjects.
Secondary objectives are to evaluate the pharmacokinetics of MAD0004J08, potency in terms of serum neutralisation power and immunogenicity in terms of generation of anti-drug antibodies (ADAs) after single dose of 48 mg, 100 mg and 400 mg.

12-lead ECG The data documented in this trial and the measured clinical parameters will be presented using classic descriptive statistics for quantitative variables and frequencies for qualitative variables.
A Statistical Analysis Plan will be prepared by CROSS Research S.A. Biometry Unit, approved by the Sponsor and finalised before database lock.
Safety, serum neutralising power, immunogenicity and demography data will be analysed by CROSS Research Biometry Unit using SAS® version 9.3 (TS1M1) or higher (the actual version will be stated in the final report).
Adverse events and serious adverse events (including clinically significant laboratory parameters, vital signs, ECG results and adverse reactions at the injection sites) will be listed by treatment. Number and percentage of subjects with adverse events and serious adverse events will be summarised.
Serum MAD0004J08 concentrations and pharmacokinetic parameters will be analysed using Phoenix WinNonlin® validated version 6.3 or higher (Pharsight Corporation) and SAS® version 9.3 for Windows® or higher. Pharmacokinetics data will be listed and summarised by descriptive statistics. Individual and mean concentration curves will also be generated. ADA concentrations will be summarised by descriptive statistics. Number and percentage of ADA-positive subjects will be listed and summarised by assessment time and overall. Serum neutralising power results will be listed by subject and assessment time-point and summarised by descriptive statistics.
