Blocking of IL-23 has shown a profound effect on patient outcomes in psoriasis. The current IL-23 binding monoclonal antibodies show differences in dosing regimens, pharmacokinetics, affinity for the target, and efficacy outcomes in the clinic. The goal of the current work is to use a mechanistic pharmacokinetics/pharmacodynamics mathematical model to estimate projected free IL-23 neutralization for the different therapeutic molecules and connect it to clinical efficacy outcomes. The meta-analysis indicates a sigmoid-like relationship and suggests that the best current anti-IL23 antibodies are close to saturating the efficacy that can be achieved by this pathway in psoriasis.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
