Alright help me out here; this is pretty implausible, right?
Why would be pts be 11% more adherent to UPA? What's the bio-plausibility here? UPA 10% better than other JAKs?
Could do a network meta analysis; betting this doens't replicate

No Increase in Cardiovascular Events with JAK Inhibitors in IBD Patients
UMKC researchers have compared the use of JAK inhibitors versus tumor necrosis factor (TNF) blockers in inflammatory bowel disease (IBD) patients, but failed to see an increase in major adverse… https://t.co/IOzckJIfYf https://t.co/8S6FnffVLG

TYK2/JAK1 in Dermato? Interesting pre-clinical study of brepocitinib... but we really just need clinical data
Glad to see this is headed straight to a Phase 3! Hoping they allow IVIG: has been a problem with many/most/all? recent dermato studies

In this large 🇦🇺 RA cohort, median time on treatment for upadacitinib was lot higher than other JAKi
(28mo vs 17mo)
Why?
Patient selection, or a real difference between JAKi?
Would really like more comparative effectiveness data between JAKi

Spicy network SRMA, 123pts w/JAK-TNF-PLBO
TNF >> JAK w/respect to malignancy (expected) & better than PLBO (spicy!)
JAK > PLBO for heme cancers (makes sense); no significant (but slight trend) toward PLBO > JAK for all cancer
The debate continues

Which RA patients are at increased risk of JAKi adverse events? Does disease activity matter?
in the upadacitinib ph3 trials, high disease activity pts had more:
serious infections
HZ
MACE
VTE
Active RA is a massive contributor to many AEs in JAKi pts

Gottlieb et al. TYK2i Zasocitinib in PsA. 12 week phase 2 RCT. Skin responses and MDA all favour zasocitinib but maybe not fantastic? PASI75 46%, PASI90 37%, PASI100 26%. MDA in photo. @RheumNow #ACR24 Abstr#1477 https://t.co/iX5iriESV2 https://t.co/RkEmcAZ80x

Slick poster, but must be careful w/real world data. Big risk of confounding/channeling bias
Pts with MACE risk (not always well-characterized by ICD codes) also less likely to receive JAK & therefore less liekly to have subsequent MACE
