Myelofibrosis

Is Jakafi Right for Me?


How do I know if I am a possible candidate for Jakafi?

Jakafi® (ruxolitinib) is an FDA-approved treatment option for adults with certain types of myelofibrosis (MF) and is included as part of national treatment recommendations for patients with intermediate or high-risk MF.

Your individual MF treatment options depend on your specific MF risk level and the severity of your symptoms.

If you have intermediate or high-risk MF, Jakafi may be a possible treatment option for you. Talk to your Healthcare Professional to learn what may be possible with Jakafi.

How is intermediate to high-risk MF characterized?

MF is characterized by scarring of the bone marrow (fibrosis), spleen enlargement (splenomegaly), abnormal blood counts (cytopenias) and symptom burden.

People with MF fall along a spectrum that ranges from having essentially no symptoms to having severe symptoms that affect daily living and quality of life. Myelofibrosis can occur on its own (primary myelofibrosis) or can develop from other conditions.

The risk level for MF is determined by a number of risk factors that include results of laboratory tests as well as clinical evaluation of your symptoms.


What risk factors may indicate that my MF is intermediate or high risk?

There are many things that can affect the course of your MF. These are called risk factors.

Risk factors that may be considered when determining MF risk level include:

Graphic of 65+

Age

Being over age 65

Symptoms

The presence of certain symptoms: fever, weight loss, and night sweats

Graphic of less blood cells

Anemia

A low number of red blood cells based on lab testing

Graphic of more blood cells

White blood cells

Very elevated levels of white blood cells based on lab testing

Graphic of elevated blood cells

Blasts

Elevated levels of immature blood cells, or blasts, based on lab testing

Graphic of fewer blood cells

Platelets

Low platelet count based on lab testing

Genetic factors

The number of risk factors present at the time of diagnosis can help determine how your MF will be classified and treated. It's important to be aware of how your MF may be changing over time. If you have 1 or several of the above risk factors, talk to your Healthcare Professional about your treatment possibilities. Remember, early recognition of disease progression can play an important role in how your disease may be managed.

Learn how adults in a clinical trial responded to Jakafi.

In one clinical study, it was estimated that nearly 90% of patients with primary myelofibrosis were considered to be intermediate or high risk within 1 year of their MF diagnosis.


What tools may be used to help my Healthcare Professional classify risk in MF?

Specific scoring tools may be used to determine if your MF is considered to be low, intermediate, or high risk. How your MF is classified may affect how your condition is managed.

Scoring systems may include:

  • Uses 5 specific risk factors to predict survival
  • IPSS is used to estimate prognosis at the time of diagnosis

  • Uses the same 5 specific risk factors as IPSS
  • Is used to estimate prognosis at any time during your MF journey

  • Uses the same 5 DIPSS risk factors, plus 3 additional risk factors
  • Builds upon DIPSS by using additional risk factors

Since MF is a chronic, progressive disease, early prognosis and treatment are necessary for optimal management. Be sure to talk with your Healthcare Professional about how your MF is classified.

INDICATIONS AND USAGE

INDICATIONS AND USAGE

Jakafi is a prescription medicine used to treat adults with polycythemia vera who have already taken a medicine called hydroxyurea and it did not work well enough or they could not tolerate it.

Jakafi is used to treat adults with certain types of myelofibrosis.

Jakafi is used to treat adults and children 12 years of age and older with acute graft-versus-host disease (GVHD) who have taken corticosteroids and they did not work well enough.

Jakafi is also used to treat adults and children 12 years of age and older with chronic GVHD who have taken one or two types of treatments and they did not work well enough.

Important Safety Information

Jakafi can cause serious side effects, including:

Low blood counts: Jakafi® (ruxolitinib) may cause low platelet, red blood cell, and white blood cell counts. If you develop bleeding, stop taking Jakafi and call your healthcare provider. Your healthcare provider will do a blood test to check your blood counts before you start Jakafi and regularly during your treatment. Your healthcare provider may change your dose of Jakafi or stop your treatment based on the results of your blood tests. Tell your healthcare provider right away if you develop or have worsening symptoms such as unusual bleeding, bruising, tiredness, shortness of breath, or a fever.

Infection: You may be at risk for developing a serious infection during treatment with Jakafi. Tell your healthcare provider if you develop any of the following symptoms of infection: chills, nausea, vomiting, aches, weakness, fever, painful skin rash or blisters.

Cancer: Some people have had certain types of non-melanoma skin cancers during treatment with Jakafi. Your healthcare provider will regularly check your skin during your treatment with Jakafi. Tell your healthcare provider if you develop any new or changing skin lesions during treatment with Jakafi.

Increases in cholesterol: You may have changes in your blood cholesterol levels during treatment with Jakafi. Your healthcare provider will do blood tests to check your cholesterol levels about every 8 to 12 weeks after you start taking Jakafi, and as needed.

Increased risk of major cardiovascular events such as heart attack, stroke or death in people who have cardiovascular risk factors and who are current or past smokers while using another JAK inhibitor to treat rheumatoid arthritis: Get emergency help right away if you have any symptoms of a heart attack or stroke while taking Jakafi, including: discomfort in the center of your chest that lasts for more than a few minutes, or that goes away and comes back, severe tightness, pain, pressure, or heaviness in your chest, throat, neck, or jaw, pain or discomfort in your arms, back, neck, jaw, or stomach, shortness of breath with or without chest discomfort, breaking out in a cold sweat, nausea or vomiting, feeling lightheaded, weakness in one part or on one side of your body, slurred speech.

Increased risk of blood clots: Blood clots in the veins of your legs (deep vein thrombosis, DVT) or lungs (pulmonary embolism, PE) have happened in people taking another JAK inhibitor for rheumatoid arthritis and may be life-threatening. Tell your healthcare provider right away if you have any signs and symptoms of blood clots during treatment with Jakafi, including: swelling, pain, or tenderness in one or both legs, sudden, unexplained chest or upper back pain, shortness of breath or difficulty breathing.

Possible increased risk of new (secondary) cancers: People who take another JAK inhibitor for rheumatoid arthritis have an increased risk of new (secondary) cancers, including lymphoma and other cancers. People who smoke or who smoked in the past have an added risk of new cancers.

The most common side effects of Jakafi include: for certain types of myelofibrosis (MF) and polycythemia vera (PV) – low platelet or red blood cell counts, bruising, dizziness, headache, and diarrhea; for acute GVHD – low platelet counts, low red or white blood cell counts, infections, and swelling; and for chronic GVHD – low red blood cell or platelet counts and infections including viral infections.

These are not all the possible side effects of Jakafi. Ask your pharmacist or healthcare provider for more information. Call your doctor for medical advice about side effects.

Before taking Jakafi, tell your healthcare provider about: all the medications, vitamins, and herbal supplements you are taking and all your medical conditions, including if you have an infection, have or had low white or red blood cell counts, have or had tuberculosis (TB) or have been in close contact with someone who has TB, had shingles (herpes zoster), have or had hepatitis B, have or had liver or kidney problems, are on dialysis, have high cholesterol or triglycerides, had cancer, are a current or past smoker, had a blood clot, heart attack, other heart problems or stroke, or have any other medical condition. Take Jakafi exactly as your healthcare provider tells you. Do not change your dose or stop taking Jakafi without first talking to your healthcare provider.

Women should not take Jakafi while pregnant or planning to become pregnant. Do not breastfeed during treatment with Jakafi and for 2 weeks after the final dose.
