Study design details

Main study objective

The study aims to evaluate potential excess risks associated with the use of brodalumab in the treatment of psoriasis with regards to:
1) Suicidal attempts (fatal or non-fatal),
2) Serious infections (incident serious chronic infections or serious infections leading to hospitalization),
3) MACE (acute myocardial infarction, stroke or cardiovascular death),
4) Malignancies

Outcomes

1) Suicidal attempts (fatal or non-fatal),
2) Serious infections (incident serious chronic infections or serious infections leading to hospitalization),
3) MACE (acute myocardial infarction, stroke or cardiovascular death),
4) Malignancies

Data analysis plan

Two different designs are used:
A case-time-control design is used in the analysis of 1) serious infections 2) suicidal behaviour and 3) MACE. In this design a patient´s risk of experiencing an outcome while being exposed to brodalumab is compared to the same patient´s risk of an outcome while not being exposed. Due to the inherently matched nature of the case-time-control design conditional logistic regression is used to calculate odds ratios.
An active-comparator cohort design is used in the analysis of 1) serious infections, 2) suicidal behaviour, 3) MACE, and 4) malignancies. In this design, the event rate of outcomes among subjects exposed to brodalumab is compared to the event rate of outcomes among subjects who are exposed to other biological drugs. In the cohort design propensity score matching is used to adjust for confounding, whereas Cox proportional hazard model is used to calculate hazard ratios.
