New humira copycat under the microscope: will it match up?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Willingness to refrain from smoking within 2 hours before the IP administration and then 2 hours before each measurement of blood pressure (BP), wrist pulse rate, respiratory rate, blood sampling, ECG. 16. Willingness to refrain from vaccination with live attenuated vaccines (e.g., intranasal influenza, measles, mumps, rubella, polio, BCG, yellow fever, chickenpox, and typhoid TY21a vaccines) throughout the study. 17.

Exclusion Criteria: 1. Mental illness or other conditions that may, in the Investigator's opinion, affect the subject's ability to comply with the Study Protocol. 2. Any significant, in the Investigator's opinion, surgical procedures performed less than 30 days before the screening examination and potentially affecting clinical study results. 3.

Known allergy or intolerance to monoclonal antibody products (murine, chimeric, humanized, fully human) or any other components of the IP. 5.
