Jakafi® (ruxolitinib) Dosing Guide for Myelofibrosis
Transcript of Jakafi® (ruxolitinib) Dosing Guide for Myelofibrosis
Indications and UsageJakafi is indicated for treatment of intermediate or high-risk myelofibrosis (MF), including primary MF, post–polycythemia vera MF and post–essential thrombocythemia MF in adults.
Important safety considerations Treatment with Jakafi can cause thrombocytopenia, anemia and neutropenia, which are each dose-related effects. Perform a pre-treatment complete blood count (CBC) and monitor CBCs every 2 to 4 weeks until doses are stabilized, and then as clinically indicated
Serious bacterial, mycobacterial, fungal and viral infections have occurred. Delay starting Jakafi until active serious infections have resolved. Observe patients receiving Jakafi for signs and symptoms of infection and manage promptly. Use active surveillance and prophylactic antibiotics according to clinical guidelines

Important Safety InformationTreatment with Jakafi® (ruxolitinib) can cause thrombocytopenia, anemia and neutropenia, which are each dose-relatedeffects. Perform a pre-treatment complete blood count (CBC) and monitor CBCs every 2 to 4 weeks until doses arestabilized, and then as clinically indicated
Manage thrombocytopenia by reducing the dose or temporarily interrupting Jakafi. Platelet transfusions may be necessary
Patients developing anemia may require blood transfusions and/or dose modifications of Jakafi
Severe neutropenia (ANC <0.5 × 109/L) was generally reversible by withholding Jakafi until recovery
Serious bacterial, mycobacterial, fungal and viral infections have occurred. Delay starting Jakafi until active seriousinfections have resolved. Observe patients receiving Jakafi for signs and symptoms of infection and manage promptly.Use active surveillance and prophylactic antibiotics according to clinical guidelines
Tuberculosis (TB) infection has been reported. Observe patients taking Jakafi for signs and symptoms of active TB andmanage promptly. Prior to initiating Jakafi, evaluate patients for TB risk factors and test those at higher risk for latentinfection. Consult a physician with expertise in the treatment of TB before starting Jakafi in patients with evidence of activeor latent TB. Continuation of Jakafi during treatment of active TB should be based on the overall risk-benefit determination
Progressive multifocal leukoencephalopathy (PML) has occurred with Jakafi treatment. If PML is suspected, stop Jakafiand evaluate
Advise patients about early signs and symptoms of herpes zoster and to seek early treatment
Increases in hepatitis B viral load with or without associated elevations in alanine aminotransferase and aspartateaminotransferase have been reported in patients with chronic hepatitis B virus (HBV) infections. Monitor and treatpatients with chronic HBV infection according to clinical guidelines
When discontinuing Jakafi, myeloproliferative neoplasm-related symptoms may return within one week. Afterdiscontinuation, some patients with myelofibrosis have experienced fever, respiratory distress, hypotension, DIC, ormulti-organ failure. If any of these occur after discontinuation or while tapering Jakafi, evaluate and treat any intercurrentillness and consider restarting or increasing the dose of Jakafi. Instruct patients not to interrupt or discontinue Jakafiwithout consulting their physician. When discontinuing or interrupting Jakafi for reasons other than thrombocytopenia orneutropenia, consider gradual tapering rather than abrupt discontinuation
Non-melanoma skin cancers including basal cell, squamous cell, and Merkel cell carcinoma have occurred. Performperiodic skin examinations
Treatment with Jakafi has been associated with increases in total cholesterol, low-density lipoprotein cholesterol, andtriglycerides. Assess lipid parameters 8-12 weeks after initiating Jakafi. Monitor and treat according to clinical guidelinesfor the management of hyperlipidemia
In myelofibrosis and polycythemia vera, the most common nonhematologic adverse reactions (incidence ≥15%) werebruising, dizziness, headache, and diarrhea. In acute graft-versus-host disease, the most common nonhematologicadverse reactions (incidence >50%) were infections and edema
Dose modifications may be required when administering Jakafi with strong CYP3A4 inhibitors or fluconazole or in patientswith renal or hepatic impairment. Patients should be closely monitored and the dose titrated based on safety and efficacy
Use of Jakafi during pregnancy is not recommended and should only be used if the potential benefit justifies the potentialrisk to the fetus. Women taking Jakafi should not breastfeed during treatment and for 2 weeks after the final dose

* COMFORT-I (COntrolled MyeloFibrosis study with ORal JAK inhibitorTreatment-I) was a randomized, double-blind, placebo-controlled phase 3study with 309 patients with intermediate-2–risk or high-risk myelofibrosis.The primary endpoint was the proportion of subjects achieving a ≥35%reduction in spleen volume from baseline to week 24 as measured by CT or MRI. A secondary endpoint was the proportion of subjects with a ≥50% reduction in Total Symptom Score from baseline to week 24 as measured by the daily patient diary, the modified Myelofibrosis Symptom Assessment Form.1,2
‡ COMFORT-II (COntrolled MyeloFibrosis study with ORal JAK inhibitorTreatment-II) was a randomized, open-label phase 3 study with 219 patients with intermediate-2–risk or high-risk myelofibrosis. The primary endpointwas the proportion of patients achieving a ≥35% reduction in spleen volume from baseline at week 48 as measured by CT or MRI. Best available therapyin COMFORT-II included hydroxyurea (46.6%) and glucocorticoids (16.4%), as well as no medication, anagrelide, epoetin alfa, thalidomide, lenalidomide,mercaptopurine, thioguanine, danazol, peginterferon alfa-2a, interferon-α, melphalan, acetylsalicylic acid, cytarabine, and colchicine.1,4,5

Early dose adjustments as needed help to optimize efficacy and safety In the phase 3 COMFORT-I trial of patients with intermediate-2–risk or high-risk MF, the primary endpoint was the proportion of patients achieving a ≥35% reduction in spleen volume from baseline to week 24.1,2*
42% of patients receiving Jakafi achieved a ≥35%reduction in spleen volume at week 24 vs 0.7% of patients receiving placebo (P < 0.0001)2
Based on limited clinical data, long-term maintenance at 5-mg twice-daily dosing has not shown responses. Continued use at this dose should be limited to patients in whom the benefits outweigh the potential risks

In COMFORT-I, 60% of patients treated with Jakafi and 38% of patients receiving placebo received red blood cell transfusions during randomized treatment1
In patients receiving Jakafi in the COMFORT studies, mean decreases in hemoglobin reached a nadir of approximately 1.5 to 2.0 g/dL below baseline after 8 to 12 weeks of therapy and then gradually recovered to a new steady state that was approximately 1.0 g/dL below baseline1
In COMFORT-I, grade 3 and 4 thrombocytopenia or anemia occurred in 13% and 45% of patients receiving Jakafi, respectively2
<1% of patients receiving Jakafi in the COMFORT studies discontinued due to anemia or thrombocytopenia1-4

Restarting
INTERRUPT FOR: Bleeding requiring intervention regardless of current platelet count, PLT counts <25 × 109/L, or ANC <0.5 × 109/L
RESTARTAfter recovery of PLT counts to >35 × 109/L and ANC >0.75 × 109/L at the higher of:
5 mg once daily or 5 mg twice daily below the largest dose in the week prior to the decrease in PLT count below 25 × 109/L or ANC below 0.5 × 109/L that led to dose interruption
Only after the first 4 weeks of therapy and not more frequently than every 2 weeks if patient meets all these criteria:
Insufficient spleen reduction*
PLT count has remained ≥40 × 109/L and has not decreased by >20% in the prior 4 weeks
ANC >1.0 × 109/L
No dose reduction or interruption for an adverse event or hematological toxicity in the prior 4 weeks
Increase dose by increments of 5 mg daily to a maximum of 10 mg twice daily
Continuation of treatment for more than 6 months should be limited to patients in whom the benefits outweigh the risks. Discontinue Jakafi® (ruxolitinib) if there is no spleen size reduction or symptom improvement after 6 months of therapy.
Reduce the dose of Jakafi in patients with platelet counts <35 × 109/L
PLT, platelet.
Starting PLT Count 50 to <100 × 109/L

PLT Count Dosing Recommendations
<25 × 109/L • Interrupt dosing
25 to <35 × 109/L and the platelet count decline is <20% during the prior 4 weeks
• Decrease dose by 5 mg once daily
• For patients on 5 mg once daily, maintain dose at 5 mg once daily
25 to <35 × 109/L and the platelet count decline is ≥20% during the prior 4 weeks
• Decrease dose by 5 mg twice daily
• For patients on 5 mg twice daily, decrease the dose to 5 mgonce daily
• For patients on 5 mg once daily, maintain dose at 5 mg once daily
The recommended starting dose in MF for patients with a starting PLT count of 50 to <100 × 109/L is 5 mg twice daily
See SPECIAL POPULATIONS tab for dosing information in patients with renal or hepatic impairment and for information on drug interactions.
Please see Important Safety Information on the back cover for related and other risk information.Refer to the accompanying Full Prescribing Information for complete dosing recommendations.
Restarting dose in case of bleedingOnce the bleeding event has resolved, consider resuming treatment at the priordose if the underlying cause of bleeding has been controlled. If the bleeding eventhas resolved but the underlying cause persists, consider resuming treatment withJakafiat a lower dose
Restarting dose in case of hematologic toxicity inpatients with starting PLT count ≥100 × 109/L
Treatment interruption and restarting dosingAfter recovery of PLT counts >50 × 109/L and ANC >0.75 × 109/L, dosing may be restarted
The maximum allowable dose that may be used in restarting Jakafi® (ruxolitinib)after a previous interruption is as shown below
Maximum restarting doses for Jakafi aftersafety interruption for thrombocytopenia
Following treatment interruption for ANC <0.5 × 109/L, after ANC recoversto ≥0.75 × 109/L, restart dosing at the higher of 5 mg once daily or 5 mg twicedaily below the largest dose in the week prior to the treatment interruption
Current PLT Count (× 109/L)
Maximum Dose When Restarting Treatment With Jakafia
≥125 20 mg twice daily
100 to <125 15 mg twice daily
75 to <100 10 mg twice daily for at least 2 weeks; if stable,may increase to 15 mg twice daily
50 to <75 5 mg twice daily for at least 2 weeks; if stable,may increase to 10 mg twice daily
<50 Continue hold
a Maximum doses are displayed. When restarting, begin with a dose at least 5 mg twice daily below the dose at interruption.

Restarting After Safety Interruption
Drug interactions
Modify the dose of Jakafi® (ruxolitinib) when coadministered with strongCYP3A4 inhibitors and fluconazole doses of ≤200 mg
Avoid the use of fluconazole doses of >200 mg daily with Jakafi
Additional dose modifications should be made with careful monitoring of safetyand efficacy
Please see Important Safety Information on the back cover for related and other risk information.Refer to the accompanying Full Prescribing Information for complete dosing recommendations.

Important S
afety Information
Treatment w
ith Jakafi® (ruxolitinib) can cause throm
bocytopenia, anemia and neutropenia, w
hich are each dose-relatedeffects. Perform
a pre-treatment com
plete blood count (CBC) and monitor CBCs every 2 to 4 w
eeks until doses arestabilized, and then as clinically indicated
Manage throm
bocytopenia by reducing the dose or temporarily interrupting Jakafi. Platelet transfusions m
ay be necessary
Patients developing anemia m
ay require blood transfusions and/or dose modifications of Jakafi
Severe neutropenia (ANC <0.5 × 10
9/L) was generally reversible by w
ithholding Jakafi until recovery
Serious bacterial, mycobacterial, fungal and viral infections have occurred. Delay starting Jakafi until active serious
infections have resolved. Observe patients receiving Jakafi for signs and symptom
s of infection and manage prom
ptly.Use active surveillance and prophylactic antibiotics according to clinical guidelines
Tuberculosis (TB) infection has been reported. Observe patients taking Jakafi for signs and symptom
s of active TB andm
anage promptly. Prior to initiating Jakafi, evaluate patients for TB risk factors and test those at higher risk for latent
infection. Consult a physician with expertise in the treatm
ent of TB before starting Jakafi in patients with evidence of active
or latent TB. Continuation of Jakafi during treatment of active TB should be based on the overall risk-benefit determ
ination
Progressive multifocal leukoencephalopathy (PM
L) has occurred with Jakafi treatm
ent. If PML is suspected, stop Jakafi
and evaluate
Advise patients about early signs and symptom
s of herpes zoster and to seek early treatment
Increases in hepatitis B viral load with or w
ithout associated elevations in alanine aminotransferase and aspartate
aminotransferase have been reported in patients w
ith chronic hepatitis B virus (HBV) infections. Monitor and treat
patients with chronic HBV infection according to clinical guidelines
When discontinuing Jakafi, m
yeloproliferative neoplasm-related sym
ptoms m
ay return within one w
eek. Afterdiscontinuation, som
e patients with m
yelofibrosis have experienced fever, respiratory distress, hypotension, DIC, orm
ulti-organ failure. If any of these occur after discontinuation or while tapering Jakafi, evaluate and treat any intercurrent
illness and consider restarting or increasing the dose of Jakafi. Instruct patients not to interrupt or discontinue Jakafiw
ithout consulting their physician. When discontinuing or interrupting Jakafi for reasons other than throm
bocytopenia orneutropenia, consider gradual tapering rather than abrupt discontinuation
Non-m
elanoma skin cancers including basal cell, squam
ous cell, and Merkel cell carcinom
a have occurred. Performperiodic skin exam
inations
Treatment w
ith Jakafi has been associated with increases in total cholesterol, low
-density lipoprotein cholesterol, andtriglycerides. Assess lipid param
eters 8-12 weeks after initiating Jakafi. M
onitor and treat according to clinical guidelinesfor the m
anagement of hyperlipidem
ia
In myelofibrosis and polycythem
ia vera, the most com
mon nonhem
atologic adverse reactions (incidence ≥15%) w
erebruising, dizziness, headache, and diarrhea. In acute graft-versus-host disease, the m
ost comm
on nonhematologic
adverse reactions (incidence >50%) w
ere infections and edema
Dose modifications m
ay be required when adm
inistering Jakafi with strong CYP3A4 inhibitors or fluconazole or in patients
with renal or hepatic im
pairment. Patients should be closely m
onitored and the dose titrated based on safety and efficacy
Use of Jakafi during pregnancy is not recomm
ended and should only be used if the potential benefit justifies the potentialrisk to the fetus. W
omen taking Jakafi should not breastfeed during treatm
ent and for 2 weeks after the final dose

Restarting
INTERRUPT FOR:Bleeding requiring intervention regardless of current platelet count,PLT counts <25 × 109/L, or
ANC <0.5 × 109/LRESTARTAfter recovery of PLT counts to >35 × 109/L and ANC >0.75 × 109/L at the higher of:
5 mg once daily or
5 mg twice daily below the largest dose in the week prior to the decrease in PLTcount below 25 × 109/L or ANC below 0.5 × 109/L that led to dose interruption
Please see Important Safety Information on the back cover for related and other risk information.Refer to the accompanying Full Prescribing Information for complete dosing recommendations.
Only after the first 4 weeks of therapy and not more frequently than every 2 weeks ifpatient meets all these criteria:
Insufficient spleen reduction*
PLT count has remained ≥40 × 109/L and has not decreased by >20% in the prior 4 weeks
ANC >1.0 × 109/L
No dose reduction or interruption for an adverse event or hematological toxicityin the prior 4 weeks
Increase dose by increments of 5 mg daily to a maximum of 10 mg twice daily
Continuation of treatment for more than 6 months should be limited to patientsin whom the benefits outweigh the risks.Discontinue Jakafi® (ruxolitinib) if there is no spleen size reduction or symptomimprovement after 6 months of therapy.
Reduce the dose of Jakafi in patients with platelet counts <35 × 109/L
PLT, platelet.
Starting PLT Count 50 to <100 × 109/L
INCREASE DOSE
DECREASE DOSE
* Failure to achieve a reduction from pre-treatment baseline in either palpable spleen length of 50% or spleen volume of 35%as measured by CT or MRI.

PLT Count Dosing Recommendations
<25 × 109/L • Interrupt dosing
25 to <35 × 109/L and theplatelet count decline is <20%during the prior 4 weeks
• Decrease dose by 5 mg once daily
• For patients on 5 mg once daily, maintain dose at 5 mg once daily
25 to <35 × 109/L and theplatelet count decline is ≥20%during the prior 4 weeks
• Decrease dose by 5 mg twice daily
• For patients on 5 mg twice daily, decrease the dose to 5 mgonce daily
• For patients on 5 mg once daily, maintain dose at 5 mg once daily
The recommended starting dose in MF for patients with a starting PLT count of50 to <100 × 109/L is 5 mg twice daily
See SPECIAL POPULATIONS tab for dosing information in patients with renal or hepaticimpairment and for information on drug interactions.
Restarting dose in case of bleeding Once the bleeding event has resolved, consider resuming treatment at the prior dose if the underlying cause of bleeding has been controlled. If the bleeding event has resolved but the underlying cause persists, consider resuming treatment with Jakafi at a lower dose
Restarting dose in case of hematologic toxicity in patients with starting PLT count ≥100 × 109/L
Treatment interruption and restarting dosing After recovery of PLT counts >50 × 109/L and ANC >0.75 × 109/L, dosing may be restarted
The maximum allowable dose that may be used in restarting Jakafi® (ruxolitinib) after a previous interruption is as shown below
Maximum restarting doses for Jakafi after safety interruption for thrombocytopenia
Following treatment interruption for ANC <0.5 × 109/L, after ANC recovers to ≥0.75 × 109/L, restart dosing at the higher of 5 mg once daily or 5 mg twice daily below the largest dose in the week prior to the treatment interruption
Current PLT Count (× 109/L)
Maximum Dose When Restarting Treatment With Jakafia
≥125 20 mg twice daily
100 to <125 15 mg twice daily
75 to <100 10 mg twice daily for at least 2 weeks; if stable, may increase to 15 mg twice daily
50 to <75 5 mg twice daily for at least 2 weeks; if stable, may increase to 10 mg twice daily
<50 Continue hold
a Maximum doses are displayed. When restarting, begin with a dose at least 5 mg twice daily below the dose at interruption.
PLT, platelet.
Restarting After Safety Interruption
Drug interactions
Modify the dose of Jakafi® (ruxolitinib) when coadministered with strongCYP3A4 inhibitors and fluconazole doses of ≤200 mg
Avoid the use of fluconazole doses of >200 mg daily with Jakafi
Additional dose modifications should be made with careful monitoring of safetyand efficacy
Please see Important Safety Information on the back cover for related and other risk information.Refer to the accompanying Full Prescribing Information for complete dosing recommendations.
Renal or hepatic impairment

Important S
afety Information
Treatment w
ith Jakafi® (ruxolitinib) can cause throm
bocytopenia, anemia and neutropenia, w
hich are each dose-relatedeffects. Perform
a pre-treatment com
plete blood count (CBC) and monitor CBCs every 2 to 4 w
eeks until doses arestabilized, and then as clinically indicated
Manage throm
bocytopenia by reducing the dose or temporarily interrupting Jakafi. Platelet transfusions m
ay be necessary
Patients developing anemia m
ay require blood transfusions and/or dose modifications of Jakafi
Severe neutropenia (ANC <0.5 × 10
9/L) was generally reversible by w
ithholding Jakafi until recovery
Serious bacterial, mycobacterial, fungal and viral infections have occurred. Delay starting Jakafi until active serious
infections have resolved. Observe patients receiving Jakafi for signs and symptom
s of infection and manage prom
ptly.Use active surveillance and prophylactic antibiotics according to clinical guidelines
Tuberculosis (TB) infection has been reported. Observe patients taking Jakafi for signs and symptom
s of active TB andm
anage promptly. Prior to initiating Jakafi, evaluate patients for TB risk factors and test those at higher risk for latent
infection. Consult a physician with expertise in the treatm
ent of TB before starting Jakafi in patients with evidence of active
or latent TB. Continuation of Jakafi during treatment of active TB should be based on the overall risk-benefit determ
ination
Progressive multifocal leukoencephalopathy (PM
L) has occurred with Jakafi treatm
ent. If PML is suspected, stop Jakafi
and evaluate
Advise patients about early signs and symptom
s of herpes zoster and to seek early treatment
Increases in hepatitis B viral load with or w
ithout associated elevations in alanine aminotransferase and aspartate
aminotransferase have been reported in patients w
ith chronic hepatitis B virus (HBV) infections. Monitor and treat
patients with chronic HBV infection according to clinical guidelines
When discontinuing Jakafi, m
yeloproliferative neoplasm-related sym
ptoms m
ay return within one w
eek. Afterdiscontinuation, som
e patients with m
yelofibrosis have experienced fever, respiratory distress, hypotension, DIC, orm
ulti-organ failure. If any of these occur after discontinuation or while tapering Jakafi, evaluate and treat any intercurrent
illness and consider restarting or increasing the dose of Jakafi. Instruct patients not to interrupt or discontinue Jakafiw
ithout consulting their physician. When discontinuing or interrupting Jakafi for reasons other than throm
bocytopenia orneutropenia, consider gradual tapering rather than abrupt discontinuation
Non-m
elanoma skin cancers including basal cell, squam
ous cell, and Merkel cell carcinom
a have occurred. Performperiodic skin exam
inations
Treatment w
ith Jakafi has been associated with increases in total cholesterol, low
-density lipoprotein cholesterol, andtriglycerides. Assess lipid param
eters 8-12 weeks after initiating Jakafi. M
onitor and treat according to clinical guidelinesfor the m
anagement of hyperlipidem
ia
In myelofibrosis and polycythem
ia vera, the most com
mon nonhem
atologic adverse reactions (incidence ≥15%) w
erebruising, dizziness, headache, and diarrhea. In acute graft-versus-host disease, the m
ost comm
on nonhematologic
adverse reactions (incidence >50%) w
ere infections and edema
Dose modifications m
ay be required when adm
inistering Jakafi with strong CYP3A4 inhibitors or fluconazole or in patients
with renal or hepatic im
pairment. Patients should be closely m
onitored and the dose titrated based on safety and efficacy
Use of Jakafi during pregnancy is not recomm
ended and should only be used if the potential benefit justifies the potentialrisk to the fetus. W
omen taking Jakafi should not breastfeed during treatm
ent and for 2 weeks after the final dose

Restarting
INTERRUPT FOR:Bleeding requiring intervention regardless of current platelet count,PLT counts <25 × 109/L, or
ANC <0.5 × 109/LRESTARTAfter recovery of PLT counts to >35 × 109/L and ANC >0.75 × 109/L at the higher of:
5 mg once daily or
5 mg twice daily below the largest dose in the week prior to the decrease in PLTcount below 25 × 109/L or ANC below 0.5 × 109/L that led to dose interruption
Please see Important Safety Information on the back cover for related and other risk information.Refer to the accompanying Full Prescribing Information for complete dosing recommendations.
Only after the first 4 weeks of therapy and not more frequently than every 2 weeks ifpatient meets all these criteria:
Insufficient spleen reduction*

Important Safety Information Treatment with Jakafi® (ruxolitinib) can cause thrombocytopenia, anemia and neutropenia, which are each dose-related effects. Perform a pre-treatment complete blood count (CBC) and monitor CBCs every 2 to 4 weeks until doses are stabilized, and then as clinically indicated
Manage thrombocytopenia by reducing the dose or temporarily interrupting Jakafi. Platelet transfusions may be necessary
Patients developing anemia may require blood transfusions and/or dose modifications of Jakafi
Severe neutropenia (ANC <0.5 × 109/L) was generally reversible by withholding Jakafi until recovery
Serious bacterial, mycobacterial, fungal and viral infections have occurred. Delay starting Jakafi until active serious infections have resolved. Observe patients receiving Jakafi for signs and symptoms of infection and manage promptly. Use active surveillance and prophylactic antibiotics according to clinical guidelines
Tuberculosis (TB) infection has been reported. Observe patients taking Jakafi for signs and symptoms of active TB and manage promptly. Prior to initiating Jakafi, evaluate patients for TB risk factors and test those at higher risk for latent infection. Consult a physician with expertise in the treatment of TB before starting Jakafi in patients with evidence of active or latent TB. Continuation of Jakafi during treatment of active TB should be based on the overall risk-benefit determination
Progressive multifocal leukoencephalopathy (PML) has occurred with Jakafi treatment. If PML is suspected, stop Jakafi and evaluate
Advise patients about early signs and symptoms of herpes zoster and to seek early treatment
Increases in hepatitis B viral load with or without associated elevations in alanine aminotransferase and aspartate aminotransferase have been reported in patients with chronic hepatitis B virus (HBV) infections. Monitor and treat patients with chronic HBV infection according to clinical guidelines
When discontinuing Jakafi, myeloproliferative neoplasm-related symptoms may return within one week. After discontinuation, some patients with myelofibrosis have experienced fever, respiratory distress, hypotension, DIC, or multi-organ failure. If any of these occur after discontinuation or while tapering Jakafi, evaluate and treat any intercurrent illness and consider restarting or increasing the dose of Jakafi. Instruct patients not to interrupt or discontinue Jakafi without consulting their physician. When discontinuing or interrupting Jakafi for reasons other than thrombocytopenia or neutropenia, consider gradual tapering rather than abrupt discontinuation
Non-melanoma skin cancers including basal cell, squamous cell, and Merkel cell carcinoma have occurred. Perform periodic skin examinations
Treatment with Jakafi has been associated with increases in total cholesterol, low-density lipoprotein cholesterol, and triglycerides. Assess lipid parameters 8-12 weeks after initiating Jakafi. Monitor and treat according to clinical guidelines for the management of hyperlipidemia
In myelofibrosis and polycythemia vera, the most common nonhematologic adverse reactions (incidence ≥15%) were bruising, dizziness, headache, and diarrhea. In acute graft-versus-host disease, the most common nonhematologic adverse reactions (incidence >50%) were infections and edema
Dose modifications may be required when administering Jakafi with strong CYP3A4 inhibitors or fluconazole or in patients with renal or hepatic impairment. Patients should be closely monitored and the dose titrated based on safety and efficacy
Use of Jakafi during pregnancy is not recommended and should only be used if the potential benefit justifies the potential risk to the fetus. Women taking Jakafi should not breastfeed during treatment and for 2 weeks after the final dose

INCREASE DOSE
DECREASE DOSE
In the case of an insufficient response, consider an increase in the doseif patient meets all these criteria:
Insufficient spleen reduction†
PLT count >125 × 109/L at 4 weeks and never <100 × 109/L
Absolute neutrophil count (ANC) >0.75 × 109/L
Increase dose by 5-mg twice-daily increments to a maximum of 25 mgtwice daily
Doses should not be increased during the first 4 weeks of therapy and notmore frequently than every 2 weeks.
Discontinue Jakafi if there is no spleen size reduction or symptomimprovement after 6 months of therapy.
