Guselkumab Pharmacology
Mechanism of action
Guselkumab targets the IL-23 subunit alpha (p19 subunit)[ 11] preventing it from binding to cell receptors that would otherwise be activated by its presence.[ 12]
Pharmacokinetics
Cmax 8.09 μg/mL
tmax 5.5 days
volume of distribution 13.5 L
apparent clearance 0.516 L/day[ 12]
Society and culture
Economics
The list price of each 100 mg dose is about US$10,000 .[ 22]
Names
During development, guselkumab was referred to as CNTO-1959.[ 12]
Research
Guselkumab has undergone phase III clinical trials comparing it with adalimumab (Humira) and ustekinumab (Stelara).[ 13]
The safety and efficacy of guselkumab was compared to a placebo and to adalimumab in the "VOYAGE 1" and "VOYAGE 2" phase III clinical trials (ClinicalTrials.gov IDs: NCT02207231 and NCT02207244).[ 23] Preliminary results indicated that a significantly higher proportion of patients taking guselkumab had better skin clearance compared to those taking the other treatments. At week 16, 73.3% of patients taking guselkumab achieved a PASI 90 (90% reduction in PASI score from baseline), vs 49.7% of those taking adalimumab; additionally, 91.2% of patients taking guselkumab achieved a PASI 75 (75% reduction in PASI score from baseline), vs 73.1% of those taking adalimumab.[ 23]
The phase III clinical trial "NAVIGATE" (ClinicalTrials.gov ID: NCT02203032) included only patients who had poor responses to treatment with ustekinumab. It showed that patients who switched to guselkumab from ustekinumab did better than those who remained on ustekinumab.[ 12] [ 24]
