Jakafi® (ruxolitinib) is an oral tablet that allows for individualized dosing1
START1
- Recommended starting dose: 5 mg orally BID
- Evaluate blood parameters before and during treatment with Jakafi
- Consider increasing dose to 10 mg BID after ≥3 days of treatment if ANC and platelet count have not decreased by 50% or more relative to the first day of dosing
MONITOR1
- Dose reductions should be considered based on platelet counts, ANCs, or bilirubin elevations, or other adverse reactions as described in the Full Prescribing Information for Jakafi
OPTIMIZE1
- Doses may be modified based on safety and efficacy; appropriate doses range from 5 mg QD to 10 mg BID
- Dose reductions may be used to manage side effects: 10 mg BID may be reduced to 5 mg BID; 5 mg BID may be reduced to 5 mg QD
- Patients who are unable to tolerate Jakafi at 5 mg QD should have treatment interrupted until their clinical and/or laboratory parameters recover
- Tapering may be considered after 6 months of treatment as clinically indicated in patients who have discontinued therapeutic doses of steroids
- Taper Jakafi by 1 dose level approximately every 8 weeks (10 mg BID to 5 mg BID to 5 mg QD)
- If aGVHD signs or symptoms recur during or after the taper of Jakafi, consider retreatment
aGVHD=acute graft-versus-host disease; ANC=absolute neutrophil count; BID=twice daily; QD=once daily.
Jakafi dose modifications
View the dosing modifications for patients with cytopenias, elevated total bilirubin (with or without liver GVHD), hepatic or renal impairment, and when Jakafi is used with strong CYP3A4 inhibitors/inducers or fluconazole.
Dose modifications for cytopenias1
Clinically significant thrombocytopenia
- After supportive measures, reduce by 1 dose level
- When platelets recover to previous values, dosing may return to prior dose level
Jakafi-related ANC <1 × 109/L
- Hold for up to 14 days; resume at 1 dose level lower upon recovery
See Full Prescribing Information for further details on dose modifications and use in special populations.
ANC=absolute neutrophil count.
Dose modifications for elevated total bilirubin1
Elevated total bilirubin without liver GVHD
- 3.0 to 5.0 × ULN: Continue at 1 dose level lower until recovery
- >5.0 to 10.0 × ULN: Hold for up to 14 days until ≤1.5 × ULN; resume at current dose upon recovery
- >10.0 × ULN: Hold for up to 14 days until ≤1.5 × ULN; resume at 1 dose level lower upon recovery
Elevated total bilirubin with liver GVHD
- >3.0 × ULN: Continue at 1 dose level lower until recovery
See Full Prescribing Information for further details on dose modifications and use in special populations.
GVHD=graft-versus-host disease; ULN=upper limit of normal.
Dose modifications for hepatic or renal impairment1
Hepatic impairment
- Mild, moderate, or severe (NCI criteria without liver GVHD): No starting dose adjustment needed
- Stage 1, 2, or 3 liver aGVHD: No starting dose adjustment needed
- Stage 4 liver aGVHD: Consider 5 mg once daily
Renal impairment
- Moderate or severe: Start at 5 mg once daily
- ESRD on dialysis: Start at 5 mg once daily after dialysis session
See Full Prescribing Information for further details on dose modifications and use in special populations.
aGVHD=acute graft-versus-host disease; BID=twice daily; ESRD=end-stage renal disease; NCI=National Cancer Institute.
Dose modifications for concomitant use with strong CYP3A4 inhibitors or fluconazole1
Starting dose with strong CYP3A4 inhibitors or fluconazole
- Fluconazole doses ≤200 mg: 5 mg once daily
- Other CYP3A4 inhibitors: Monitor blood counts more frequently for toxicity and modify the Jakafi dosage for adverse reactions if they occur
See Full Prescribing Information for further details on dose modifications and use in special populations.
BID=twice daily; GVHD=graft-versus-host disease; REACH=Ruxolitinib in patiEnts with refrACtory graft-versus-Host disease after allogeneic stem cell transplantation.
