An AE is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.

Plasma concentration of Bimekizumab (BKZ) over time - at Day 43, 5 hours after dosing | ||||||||
End point description |
BKZ plasma concentration was expressed as geometric mean concentration and measure in nanograms per milillitre (ng/mL).
Note 1: Values Bellow Limit of Quantification (BLQ) are replaced by value of Lower Limit Of Quantification (LLOQ)/2 (=75ng/mL) in calculations of descriptive statistics.
Note 2: Descriptive statistics were only calculated if at least 2/3 of the concentrations were quantified at the respective timepoint.

Substantial protocol amendments (globally) |

| Were there any global substantial amendments to the protocol? Yes | |||
Date |
Amendment |
||
03 Jul 2017 |
Adjusted the timing for the Screening Visits, revised the washout duration for concomitant medications, and introduced wording for a potential interim analysis and a new stopping rule should the interim analysis be carried out. |
||
Interruptions (globally) |
|||
| Were there any global interruptions to the trial? No | |||
Limitations and caveats |
|||
| Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data. | |||
| Early study termination, due to an imbalance of adverse events with no clear evidence of benefits, resulted in a number of subjects that was too small to enable any definitive conclusions. | |||
