Jakafi® (ruxolitinib) is an oral tablet that allows for individualized dosing1
START1
- Recommended starting dose: 10 mg orally BID
- Evaluate blood parameters before and during treatment with Jakafi
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
- 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 in patients with response 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 cGVHD signs or symptoms recur during or after the taper of Jakafi, consider retreatment
ANC=absolute neutrophil count; BID=twice daily; cGVHD=chronic graft-versus-host disease; QD=once daily.
Jakafi dose modifications
View the dosing modifications for patients with cytopenias, elevated total bilirubin, hepatic or renal impairment, and when Jakafi is used with strong CYP3A4 inhibitors or fluconazole.
Dose modifications for cytopenias1
Platelet count <20 × 109/L
- Reduce Jakafi by 1 dose level. If resolved within 7 days, dosing may return to initial dose level
- If not resolved within 7 days, maintain at 1 dose level lower
Related to Jakafi use
- ANC <0.75 × 109/L
- Reduce Jakafi by 1 dose level; resume at initial dose level upon recovery
- ANC <0.5 × 109/L
- Hold Jakafi for up to 14 days; resume at 1 dose level lower upon recovery
- May resume initial dose level when ANC is greater than 1.0 × 109/L
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
- 3.0 to 5.0 × ULN: Continue Jakafi at 1 dose level lower until recovery; if resolved within 14 days, increase by 1 dose level; if not resolved within 14 days, maintain the decreased dose level
- >5.0 to 10.0 × ULN: Hold for up to 14 days until resolved; resume at current dose upon recovery; if not resolved within 14 days, resume at 1 dose level lower upon recovery
- >10.0 × ULN: Hold for up to 14 days until resolved; resume at 1 dose level lower upon recovery; if not resolved within 14 days, discontinue
See Full Prescribing Information for further details on dose modifications and use in special populations.
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
- Score 3 liver cGVHD: Monitor blood counts more frequently for toxicity and modify the Jakafi dosage for adverse reactions if they occur
Renal impairment
- Moderate or severe: Start at 5 mg BID
- ESRD on dialysis: Start at 10 mg once daily after dialysis session
See Full Prescribing Information for further details on dose modifications and use in special populations.
BID=twice daily; cGVHD=chronic graft-versus-host disease; 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 BID
- 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.
