Abstract
Background: While there are relatively large number of studies on the retention of biologics in psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA), very long-term retention studies are scarce.
Research design and methods: Retrospective longitudinal study including patients with up to a decade of follow-up. Survival rate was analyzed using Kaplan-Meier curves and drug discontinuation-associated factors using multivariate Cox regression. Hazard Ratio (HR) was used as a measure of the association.
Results: Ninety PsA patients and 93 with axSpA were included. Retention rate ranged from 64% at year 1 to 25% at year 11 in PsA, whereas in axSpA, these figures ranged from 68% at year 1 to 34% at year 12. The rate of any event leading to drug discontinuation was 20.9/100PYs and 14.8/100PYs in PsA and axSpA, respectively. Age at arthritis onset (HR 0.93, 95%CI: 0.87-0.99, p = 0.048) and psoriasis duration (HR 1.08, 95%CI: 1.0-1.2, p = 0.036) were linked to drug discontinuation in PsA. In axSpA, retention rate was significantly higher in men compared to women (long-rank p = 0.037).
Conclusion: In this real-world study, a non-negligible retention of GOL is observed. The two diseases differ in the factors that appear to determine drug persistence.
期刊介绍:
Advances in drug development technologies are yielding innovative new therapies, from potentially lifesaving medicines to lifestyle products. In recent years, however, the cost of developing new drugs has soared, and concerns over drug resistance and pharmacoeconomics have come to the fore. Adverse reactions experienced at the clinical trial level serve as a constant reminder of the importance of rigorous safety and toxicity testing. Furthermore the advent of pharmacogenomics and ‘individualized’ approaches to therapy will demand a fresh approach to drug evaluation and healthcare delivery.
Clinical Pharmacology provides an essential role in integrating the expertise of all of the specialists and players who are active in meeting such challenges in modern biomedical practice.
