For PV in adults who have had an inadequate response to HU¹

Individualized dosing for Jakafi^® (ruxolitinib)¹

Dose optimization is key to maintaining the balance between safety and efficacy

START

For patients with PV who have an inadequate response to HU, the recommended starting dose is 10 mg BID.

A CBC and platelet count must be performed before initiating Jakafi.

Jakafi is also available in tablets of:

MONITOR

A CBC and platelet count must be performed before initiating Jakafi, every 2 to 4 weeks until doses are stabilized, and then as clinically indicated.

OPTIMIZE

Individualize dosing of Jakafi to optimize the balance between safety and efficacy.

Dosing may be reduced or temporarily interrupted based on Hb, platelet, or neutrophil counts
Additionally, dosing may be increased to achieve desired clinical response
Interrupt treatment for bleeding

BID=twice daily; CBC=complete blood count; Hb=hemoglobin; HU=hydroxyurea; PV=polycythemia vera; RESPONSE=Randomized study of Efficacy and Safety in POlycythemia vera with JAK iNhibitor ruxolitinib verSus bEst available care.

Decrease dose for anemia or thrombocytopenia¹

Among those taking Jakafi in the RESPONSE trial, 5% (6/110) of patients decreased from the starting dose at week 8, and 13% (14/110) of patients decreased from the starting dose at week 32.²

BID=twice daily; Hb=hemoglobin; RESPONSE=Randomized study of Efficacy and Safety in Polycythemia vera with JAK iNhibitor ruxolitinib verSus bEst available care.

Increase dose for insufficient response¹

Doses may be increased in increments of 5 mg BID to a maximum of 25 mg BID

Doses should not be increased during the first 4 weeks of therapy and should not be increased more frequently than every 2 weeks

Consider dose increase in patients who meet all of these criteria

Among those taking Jakafi in the RESPONSE trial, 37% (41/110) of patients increased from the starting dose at week 8, and 54% (59/110) of patients increased from the starting dose at week 32.²

ANC=absolute neutrophil count; BID=twice daily; Hb=hemoglobin; RESPONSE=Randomized study of Efficacy and Safety in POlycythemia vera with JAK iNhibitor ruxolitinib verSus bEst available care; ULN=upper limit of normal; WBC=white blood cell.

Interrupting/restarting dosing¹

Interrupt Jakafi treatment for:

Anemia (Hb <8 g/dL),
Thrombocytopenia (platelet count <50 × 10⁹/L), or
Neutropenia (ANC <1.0 × 10⁹/L)

After recovery of hematologic parameter(s) to acceptable levels, dosing may be restarted

Use the most severe category of patients’ Hb, platelet count, or ANC abnormality to determine the corresponding maximum restarting dose:

^aContinue treatment for at least 2 weeks; if stable, may increase dose by 5 mg BID.

Patients who required dose interruption while receiving a dose of 5 mg BID may restart at a dose of 5 mg BID or 5 mg once daily, but not higher, when they have:

Hb ≥10 g/dL,
Platelet count ≥75 × 10⁹/L, and
ANC ≥1.5 × 10⁹/L

Dose management after restarting treatment in PV

After restarting Jakafi following treatment interruption, doses may be titrated, but the maximum total daily dose should not exceed 5 mg less than the dose that resulted in the dose interruption
An exception to this is dose interruption following phlebotomy-associated anemia, in which case the maximal total daily dose allowed after restarting Jakafi would not be limited

Special populations:

Avoid fluconazole doses >200 mg daily with Jakafi
Avoid use of Jakafi in patients with end-stage renal disease (CLcr <15 mL/min) not requiring dialysis

ANC=absolute neutrophil count; BID=twice daily; CLcr=creatinine clearance; Hb=hemoglobin; PV=polycythemia vera.

Dose modifications for special populations¹

Modify the dose of Jakafi accordingly in patients with moderate or severe renal impairment, patients with hepatic impairment, and patients on dialysis.

Real impairment status/ Hepatic impairment status, platelet count, recommended starting dose

Patients with end-stage renal disease on dialysis

The recommended starting dose in patients with PV who have end-stage renal disease (CLcr <15 mL/min) and are on dialysis is 10 mg once after dialysis session
Additional dose modifications should be made with frequent monitoring of safety and efficacy
Avoid use of Jakafi in patients with end-stage renal disease (CLcr <15 mL/min) not requiring dialysis

Concomitant use with strong CYP3A4 inhibitors or fluconazole

Modify the dose of Jakafi when coadministered with strong CYP3A4 inhibitors and fluconazole doses of ≤200 mg
Avoid the use of fluconazole doses <200 mg daily with Jakafi
Additional dose modifications should be made with frequent monitoring of safety and efficacy

For patients coadministered strong CYP3A4 inhibitors of fluconazole doses <=200mg, recommended dose modification

BID=twice daily; CLcr=creatinine clearance; PV=polycythemia vera.

Indications and Usage

Jakafi^® (ruxolitinib) is indicated for treatment of polycythemia vera (PV) in adults who have had an inadequate response to or are intolerant of hydroxyurea.

Jakafi 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.

Jakafi is indicated for treatment of steroid-refractory acute graft-versus-host disease (aGVHD) in adult and pediatric patients 12 years and older.

Jakafi is indicated for treatment of chronic graft-versus-host disease (cGVHD) after failure of one or two lines of systemic therapy in adult and pediatric patients 12 years and older.

Important Safety Information

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
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
Herpes zoster infection has been reported in patients receiving Jakafi. Advise patients about early signs and symptoms of herpes zoster and to seek early treatment. Herpes simplex virus reactivation and/or dissemination has been reported in patients receiving Jakafi. Monitor patients for the development of herpes simplex infections. If a patient develops evidence of dissemination of herpes simplex, consider interrupting treatment with Jakafi; patients should be promptly treated and monitored according to clinical guidelines
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 (NMSC) 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
Another JAK-inhibitor has increased the risk of major adverse cardiovascular events (MACE), including cardiovascular death, myocardial infarction, and stroke (compared to those treated with tumor TNF blockers) in patients with rheumatoid arthritis, a condition for which Jakafi is not indicated. Consider the benefits and risks for the individual patient prior to initiating or continuing therapy with Jakafi particularly in patients who are current or past smokers and patients with other cardiovascular risk factors. Patients should be informed about the symptoms of serious cardiovascular events and the steps to take if they occur
Another JAK-inhibitor has increased the risk of thrombosis, including deep venous thrombosis (DVT), pulmonary embolism (PE), and arterial thrombosis (compared to those treated with TNF blockers) in patients with rheumatoid arthritis, a condition for which Jakafi is not indicated. In patients with myelofibrosis (MF) and polycythemia vera (PV) treated with Jakafi in clinical trials, the rates of thromboembolic events were similar in Jakafi and control treated patients. Patients with symptoms of thrombosis should be promptly evaluated and treated appropriately
Another JAK-inhibitor has increased the risk of lymphoma and other malignancies excluding NMSC (compared to those treated with TNF blockers) in patients with rheumatoid arthritis, a condition for which Jakafi is not indicated. Patients who are current or past smokers are at additional increased risk. Consider the benefits and risks for the individual patient prior to initiating or continuing therapy with Jakafi, particularly in patients with a known secondary malignancy (other than a successfully treated NMSC), patients who develop a malignancy, and patients who are current or past smokers
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 (pathogen not specified) and edema. In chronic graft-versus-host disease, the most common nonhematologic adverse reactions (incidence >20%) were infections (pathogen not specified) and viral infections
Avoid concomitant use with fluconazole doses greater than 200 mg. Dose modifications may be required when administering Jakafi with fluconazole doses of 200 mg or less, or with strong CYP3A4 inhibitors, 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
