May be taken with or without food.

Pregnancy and lactation.

Patient with TB or risk of TB, chronic hepatitis B virus infection. Patients taking strong CYP3A4 inhibitors or dual inhibitors of CY3A4 and CYP2C9 enzymes (e.g. fluconazole). Hepatic and moderate to severe renal impairment. Treatment has been associated with increases in lipid parameters including total cholesterol, low density lipoprotein, and triglycerides; assess lipid parameters approximately 8-12 weeks following initiation of therapy; monitor according to clinical guidelines for management of hyperlipidemia. Nonmelanoma skin cancers reported including basal cell, squamous cell, and Merkel cell carcinoma. Monitor CBC with differential (prior to therapy and every 2-4 weeks until doses are stabilised, then as clinically indicated), lipid parameters, hepatic and renal function, HBV-DNA titer; signs and symptoms of infections. Evaluate patients for presence of active or latent TB prior to treatment.

Pregnancy When pregnant rats and rabbits were administered ruxolitinib during organogenesis adverse developmental outcomes occurred at doses associated with maternal toxicity There are no studies with use in pregnant women to inform drug-associated risks Lactation No data are available regarding the presence of ruxolitinib in human milk, the effects on the breast fed child, or the effects on milk production Ruxolitinib and/or its metabolites were present in the milk of lactating rats Because many drugs are present in human milk and because of the potential for thrombocytopenia and anemia shown for ruxolitinib in human studies, discontinue breastfeeding during treatment and for 2 weeks after final dose

Increased plasma concentration with strong CYP3A4 inhibitors (e.g. boceprevir, clarithromycin, indinavir, itraconazole, lopinavir, ritonavir, nelfinavir, posaconazole, saquinavir, telaprevir, telithromycin, voriconazole) and mild or moderate CYP3A4 inhibitors (e.g. ciprofloxacin, erythromycin, amprenavir, atazanavir, diltiazem, cimetidine). Decreased plasma concentration with CYP3A4 inducers (e.g. carbamazepine, phenobarbital, phenytoin, rifabutin, rifampicin). May increase plasma concentration of substances transported by P-glycoprotein and breast cancer resistance protein (e.g. dabigatran, ciclosporin, rosuvastatin, digoxin).

Ruxolitinib is a selective inhibitor of Janus Associated Kinases (JAKs), JAK1 and JAK2 which mediate the signaling of cytokines and growth factors that are important for haematopoiesis and immune function. In myelofibrosis and polycythaemia vera are known to be associated with dysregulation of JAK 1/2. JAK mediated signaling involves recruitment of signal transducers and activators of transcription (STATs) to cytokine receptors, thus leading to modulation of gene expression. JAK-STAT signaling is involved with the regulation of the development, proliferation, and activation of immune cell types important to GVHD pathogenesis.
