Plain English Summary

Background and study aims
This is a study to investigate and compare the pharmacokinetics (measuring drug levels in the blood over time), safety, tolerability and immunogenicity (blood tests to check the body's immune response to the drug) following single doses (40mg) of three different preparations of a human monoclonal antibody given by injection. This anti-inflammatory human monoclonal antibody is used to treat various autoimmune diseases such as rheumatoid arthritis and psoriasis. Two different preparations are marketed for use in the USA (USHumira) and Europe (EUHumira). Baxter Innovations GmbH (part of The Baxter Healthcare Corporation) is developing a monoclonal antibody M923 to be a similar biological medicinal product (biosimilar) to the marketed adalimumab (USHumira and EUHumira) preparations. M923 has not been given to humans before and in this study will be compared with the 2 marketed USHumira and EUHumira preparations.

Who can participate?
Healthy adults aged 18-55

What does the study involve?
After an initial review of their medical condition to ensure that they meet study requirements to take part, the participants are randomly allocated into one of two groups. Those in group 1 are given a single dose of M923. Those in group 2 are given a single dose of USHumira. Those in group 3 are given a single dose of EUHumira. The study takes place over about 9 months and involves a screening visit, a period where volunteers will be inpatients and must stay in the clinic (up to eight nights), several outpatient visits and a final follow up visit.

What are the possible benefits and risks of participating?
There is no medical benefit to the subjects as they are healthy volunteers. The possibility of side effects from the preparations of Humira and M923 is minimal not only due to the single dose used but also because previous studies with Adalimumab (Humira®) in healthy subjects demonstrated no treatment related serious side effects.

Where is the study run from?
It is a multisite study with three sites in London, Wales, and Northern Ireland

When is the study starting and how long is it expected to run for?
December 2014 to August 2015

Study information

Scientific title

A randomized, double-blind, three-arm, parallel group, single-dose study to compare the pharmacokinetics, safety, tolerability, and immunogenicity of three formulations of adalimumab (M923, US Sourced Humira and EU Sourced Humira) in healthy subjects


Study hypothesis

1. The primary objective is to investigate and compare the pharmacokinetic (PK) profiles of M923, United States of America (US) sourced Humira and European Union (EU) sourced Humira in healthy subjects.
2. The secondary objective is to investigate the safety, tolerability, and immunogenicity of M923, US sourced Humira and EU sourced Humira in healthy subjects.

Three formulations of adalimumab (M923, US Sourced Humira and EU Sourced Humira)

Intervention type



Phase I

Drug names

M923 (adalimumab), US sourced Humira (adalimumab) and EU sourced Humira (adalimumab)

Primary outcome measure

1. Observed maximum concentration (Cmax)
2. Area under the serum concentration-time curve from time zero to 336 hours [AUC(0-336)]
3. Area under the serum concentration-time curve from time zero extrapolated to infinity [AUC(0-inf)]
PK blood samples will be taken pre-dose and up to and including Day 71 post-dose.

Secondary outcome measures

1. The area under the serum concentration-time curve from time zero to 1344 hours [AUC(0-1344)]
2. Area under the serum concentration-time curve from time zero to time of the last quantifiable concentration [AUC(0-last)]
3. Time of maximum concentration (tmax)
4. Terminal rate constant (λz)
5. Terminal half- life (t1/2)
6. Apparent volume of distribution following extravascular dosing (Vz/F)
7. Apparent volume of distribution at distribution equilibrium (Vss/F)
8. Apparent systemic clearance after extravascular dosing (CL/F)
9. Area under the concentration-time curve extrapolated from time t to infinity as a percentage of total AUC (%AUCex)

Vital signs will be performed pre-dose and post-dose - ECGs will be performed pre-dose and post-dose. Clinical laboratory tests: pre-dose and post-dose. Adverse events: Day-1 till last visit. Injection site evaluation Day-1 till last visit
