The US Food and Drug Administration (FDA) has approval for the Janssen Pharmaceutical Companies of 鈥檚 Stelara (ustekinumab) to treat paediatric patients aged six years and above with active psoriatic arthritis (PsA).
The latest approval was based on pharmacokinetic (PK) findings and extrapolation of the validated efficacy and current safety profile of Stelara in various Phase III clinical trials carried out in adult and paediatric moderate-to-severe plaque psoriasis (PsO) patients and adult active PsA patients.
The Phase III PSTELLAR, CADMUS and CADMUS Jr trials enrolled PsO patients while PSUMMIT I and II studies enrolled PsA patients.
Findings showed that PK exposure of Stelara in paediatric PsO patients with active PsA was in line with that of Phase III trials of the therapy in patients without active PsA.
Furthermore, the exposure was consistent with adults having moderate to severe plaque PsO or adult active PsA patients.
A completely human monoclonal antibody, Stelara hinders cytokines interleukin (IL)-12 and IL-23.
