Drug Interaction Report

GENERALLY AVOID: Coadministration of deucravacitinib with other immunosuppressive agents may potentiate the risk of infections as well as lymphoma and other malignancies. Serious infections have been reported in patients with psoriasis who received deucravacitinib. The most common serious infections reported with deucravacitinib included pneumonia and COVID-19. Herpes zoster and herpes simplex viral reactivation were also reported during clinical studies with deucravacitinib, as well as malignancies including lymphoma.

MANAGEMENT: The safety and efficacy of deucravacitinib in combination with immunosuppressive agents has not been evaluated. The manufacturer recommends that the concomitant use of deucravacitinib with potent immunosuppressants (e.g., azathioprine, cyclosporine) should be avoided. Patients receiving deucravacitinib should be closely monitored for the development of signs and symptoms of infection during and after treatment, including the possible development of tuberculosis in patients who tested negative for latent tuberculosis infection prior to initiating therapy. If a serious infection develops, deucravacitinib should be interrupted until the infection is controlled.

ADJUST DOSING INTERVAL: Food may reduce the oral bioavailability of asciminib. When a single 40 mg dose of asciminib was administered with a low-fat meal (400 calories; 25% fat) in healthy volunteers, asciminib peak plasma concentration (Cmax) and systemic exposure (AUC) decreased by 35% and 30%, respectively, compared to asciminib administered in the fasted state. Administration with a high-fat meal (1000 calories; 50% fat) decreased the Cmax and AUC of asciminib by 68% and 62%, respectively.

MANAGEMENT: To ensure adequate asciminib exposures, food consumption should be avoided for at least 2 hours before and 1 hour after taking asciminib.
