Background:
Pain is one of the most important domains affecting health-related quality of life (HRQoL) in patients with psoriatic arthritis (PsA). Secukinumab has demonstrated rapid and sustained improvements in signs and symptoms, including HRQoL, among patients with active PsA. This analysis evaluates the effect of secukinumab on patient-reported pain in PsA through 104 weeks of treatment.
Methods:
Pain was assessed through week 104 using clinically relevant measures, including change from baseline in a pain visual analog scale (VAS) and Short Form-36 (SF-36) bodily domain scores; proportion of patients reporting improvements equal to or better than minimum clinically meaningful differences in the pain VAS and SF-36 bodily pain domain scores; and proportion of patients with no, moderate, or extreme pain/discomfort measured by the EuroQoL 5-Dimension 3-Level Questionnaire (EQ-5D-3 L) pain item scores. Correlations of pain measures were analyzed using Pearson's correlation coefficient. Pre-specified analyses of TNF-naïve patients and patients who stopped TNF-inhibitors (TNFis) due to inadequate responses or safety/tolerability (TNF-IR patients) were performed using "as-observed data."
Results:
Mean improvements from baseline in pain VAS scores were greater with secukinumab versus placebo by week 3 (- 16.9; P < 0.0001 with secukinumab 300 mg and - 12.6; P < 0.05 with secukinumab 150 mg) and sustained through week 104. SF-36 bodily pain domain scores were significantly greater with 300 mg secukinumab and secukinumab 150 mg versus placebo by week 4 (16.2 and 16.3, respectively; P < 0.0001 for both), and these changes were maintained through week 104. With both secukinumab 300 mg and secukinumab 150 mg, improvements equal to or better than the minimum clinically meaningful differences in pain VAS and SF-36 bodily pain were significant versus placebo at week 3 and week 4, respectively. At week 4, 15%, 9%, and 5% of patients receiving secukinumab 300 mg, secukinumab 150 mg, and placebo, respectively, reported "no pain/discomfort" measured by EQ-5D-3 L; these proportions increased to week 104 with both secukinumab doses. Similarly, improvements in pain measures were significant in both TNF-naïve and TNF-IR patients.
Conclusion:
Secukinumab provided rapid and sustained pain relief in PsA over 2 years of treatment. Improvements in pain were reported regardless of prior exposure to TNFis.

02:14SN2 Reaction: Kinetics
In a chemical reaction, a relationship exists between the concentration of reactants and the rate at which the reaction proceeds. The study to measure this relationship is known as the kinetics of a chemical reaction. Kinetic studies are used to deduce the rate law of a chemical reaction, which provides information about the species involved during the transition state of the rate-determining step. Thus, kinetic studies help to derive the mechanism of a...
02:27SN2 Reaction: Mechanism
The presence of the more electronegative halogen in the substrate creates a polarized carbon-halide bond. The halide pulls the electron cloud generating an electrophilic center at the carbon atom. Thus, the carbon atom carries a partial positive charge while the halide has a...
02:26SN2 Reaction: Transition State
When the nucleophile approaches the electrophilic carbon with its lone pairs, the halide acts as a leaving group and moves away with the electron-pair bonded to the carbon. Dotted partial bonds represent the bonds being formed or broken...
