Bioequivalence Phase I Study of BFI-751 Compared With EU and US-STELARA® in Healthy Adults

Study Purpose

BFI-751 is being developed by BioFactura Australia Pty Ltd as a biosimilar drug to Stelara® (EU licenced and US licenced) (ustekinumab) is a prescription biologic medicine used to treat people with Crohn's disease, Ulcerative Colitis, plaque psoriasis and psoriatic arthritis. Stelara® is an immune suppressant that reduces the effects of inflammatory proteins within the body. This is the first time BFI-751 will be given to humans. The primary purpose of this study is to compare the pharmacokinetics (the study of what the body does to the drug, referring to the movement of any drug going into, through, and out of the body) by checking to see if the blood levels of 751-BFI are comparable with US-Stelara® and EU-Stelara® following a single injection under the skin. The secondary purposes of this study are:

  • - to assess the safety of BFI-751, - study how well the healthy volunteers tolerate it and.
  • - to also assess the immune response to it in healthy volunteers.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.
