INREBIC provides new, once-daily oral option for patients affected by rare bone marrow cancer

SUMMIT, N.J.–(BUSINESS WIRE)–Celgene Corporation (NASDAQ: CELG) today announced the U.S. Food and Drug Administration (FDA) has approved INREBIC® (fedratinib) for the treatment of adult patients with intermediate-2 or high-risk primary or secondary (post-polycythemia vera or post-essential thrombocythemia) myelofibrosis.1

Celgene Fedratinib FDA approved for Myelofibrosis“The approval of INREBIC is another important milestone for Celgene and underscores our commitment to people living with blood cancers,” said Jay Backstrom, M.D., M.P.H., Chief Medical Officer for Celgene.  “We are excited to provide INREBIC as a new treatment option that may be used in patients with myelofibrosis, including patients previously treated with ruxolitinib.”

“Myelofibrosis can cause patients to suffer in many ways, including experiencing debilitating symptoms,” said Ruben Mesa, M.D., FACP, Director of the Mays Cancer Center at UT Health San Antonio Cancer Center MD Anderson.  “There has not been a new treatment approved for this disease in nearly a decade.  With INREBIC, physicians and patients now have another option available for myelofibrosis.”

The INREBIC development program consisted of multiple studies (including JAKARTA and JAKARTA2) in 608 patients who received more than one dose (ranging from 30 mg to 800 mg),1 of whom 459 had myelofibrosis,1 including 97 previously treated with ruxolitinib.1 The JAKARTA study evaluated the efficacy and safety of once-daily oral doses of INREBIC compared with placebo in patients with intermediate-2 or high-risk, primary or secondary (post-polycythemia vera or post-essential thrombocythemia) myelofibrosis who were previously untreated with a JAK inhibitor, had enlarged spleens (a condition known as splenomegaly), and had a platelet count of ≥50 x 109/L (median baseline platelet count was 214 x 109/L; 16% <100 x 109/L and 84% ≥100 x 109/L).1,2 In the JAKARTA study, spleen volume was reduced by 35% or greater, when assessed from baseline to the end of cycle 6 (week 24), with a 4-week follow-up scan, in 37% (35 of 96) of patients treated with INREBIC 400 mg versus 1% (1 of 96) of patients who received placebo (p<0.0001).1 INREBIC also improved the Total Symptom Score as measured by the modified Myelofibrosis Symptoms Assessment Form (MFSAF) v2.0 diary2 (night sweats, itching, abdominal discomfort, early satiety, pain under ribs on left side, bone or muscle pain) by 50% or greater when assessed from baseline to the end of cycle 6 in 40% of (36 of 89) patients treated with 400 mg, versus 9% (7 of 81) of patients who received placebo (p<0.0001).1

MPN Resources

These resources were originally published by MPN Cancer Connection here.


One of the first recommendations for the newly diagnosed is to see an MPN Specialist. This also applies to patients who have never seen an MPN Specialist. Financial difficulties can make this a difficult task. Before you begin treatment, patients and caregivers should meet with a financial counselor at the facility providing treatment. The counselor will assist in determining coverage and estimate out of pocket expenses. You might also consider an Oncology Nurse Navigator who helps provide support services, coordinates elements of care and helps you learn about additional cancer resources.
