The approval provides an important new treatment option for adults living with debilitating and potentially life-threatening condition

This is the first indication for IMBRUVICA outside of oncology and its sixth U.S. indication

HORSHAM, PA, August 2, 2017 – The U.S. Food and Drug Administration (FDA) has approved IMBRUVICA® (ibrutinib) for the treatment of adult patients with chronic graft-versus-host-disease (cGVHD) after failure of one or more lines of systemic therapy.[1] IMBRUVICA is the first and only FDA-approved medication for adult patients with cGVHD, a potential consequence of an allogeneic stem cell or bone marrow transplant, which can be life-threatening and debilitating.[2] IMBRUVICA is a first-in-class Bruton’s tyrosine kinase (BTK) inhibitor jointly developed and commercialized by Janssen Biotech, Inc., and Pharmacyclics LLC, an AbbVie company.

“Chronic graft-versus-host-disease can occur after allogeneic stem cell or bone marrow transplant and results from donor immune cells attacking the patient’s tissue. For most patients, the diagnosis of cGVHD comes after a long and already arduous battle with a blood-related disease,” said David Miklos, M.D., Ph.D., Associate Professor of Medicine (Blood and Marrow Transplantation), Stanford University, and lead investigator of the IMBRUVICA cGVHD clinical study.* “This approval provides physicians and the cGVHD patient community with a welcome new approach for patients who fail initial therapy, as data show treatment with IMBRUVICA resulted in encouraging and sustained clinical responses.”

The approval is based on results from an open-label, multi-center, single-arm Phase 1b/2 trial (PCYC-1129) evaluating the safety and efficacy of ibrutinib in 42 patients with cGVHD who failed first-line corticosteroid therapy and required additional therapy (median age of 56 years; range, 19 to 74 years old). In the study population, the most common underlying malignancies leading to transplantation were acute lymphocytic leukemia (ALL), acute myeloid leukemia (AML) and chronic lymphocytic leukemia (CLL). The median time since cGVHD diagnosis was 14 months, the median number of prior cGVHD treatments was two (range, one to three treatments), and 60% of patients had a Karnofsky performance score of ≤ 80. The majority of patients (88%) had at least two organs involved at the beginning of the trial, with the most commonly involved organs being mouth (86%), skin (81%) and gastrointestinal tract (33%). Fifty-two percent of patients were receiving ongoing immunosuppressants in addition to systemic corticosteroids at baseline.1

The overall response rate (ORR) was 67% (95% CI: 51%, 80%), with 21% of patients achieving complete responses (CR; n=9) and 45% achieving partial responses (PR; n=19). Sustained response rate of at least 20 weeks was 48% (n=20). The median time to best response coinciding with the first scheduled response assessment was 12.3 weeks (range, 4.1 to 42.1 weeks). Responses were seen across all involved organs for cGVHD (i.e., skin, mouth, gastrointestinal tract and liver).1

Warnings and precautions for IMBRUVICA include hemorrhage, infections, cytopenias, atrial fibrillation, hypertension, second primary malignancies, tumor lysis syndrome and embryo-fetal toxicity. The most common (>20%) adverse events (AEs) of all Grades in the cGVHD trial included fatigue (57%), bruising (40%), diarrhea (36%), thrombocytopenia (33%), stomatitis (29%), muscle spasms (29%), nausea (26%), hemorrhage (26%), anemia (24%), and pneumonia (21%). Atrial fibrillation occurred in one patient (2%), which was Grade 3. Twenty-four percent of patients receiving IMBRUVICA in the cGVHD trial discontinued treatment due to adverse reactions. The most common adverse reactions leading to discontinuation were fatigue and pneumonia. Adverse reactions leading to dose reduction occurred in 26% of patients.1

“We are very pleased to bring IMBRUVICA to physicians and patients battling chronic graft-versus-host-disease,” said Peter F. Lebowitz, M.D., Ph.D., Global Oncology Head, Janssen. “This indication for previously-treated cGVHD represents the first approved use of IMBRUVICA outside of the hematology-oncology category, and we are deeply proud of this development.”

The data was presented as a late-breaker at the American Society of Hematology Annual Meeting in December 2016 and the Blood and Marrow Transplantation Tandem Meeting in February 2017. A Phase 3 double-blind, placebo-controlled study was initiated in December 2016 to examine ibrutinib with corticosteroid versus placebo with corticosteroid as a first-line therapy for patients with new onset moderate or severe cGVHD; the study is ongoing.

Patients can develop GVHD, a potentially life-threatening complication, following an allogeneic stem cell or bone marrow transplant.2 The condition occurs when donor immune cells mistakenly attack the patients’ normal tissues.2 The effects of cGVHD can be seen throughout the body, affecting almost any organ, which may include loss of patches of skin, hair loss, excessive dryness of the body resulting in ulcers and scarring of the lungs, and liver injury leading to liver failure.2 The incidence of cGVHD has continued to increase over time,[3] with approximately 30-70% of post-allogeneic transplant patients developing the condition.[4]

Janssen and Pharmacyclics are continuing an extensive clinical development program for IMBRUVICA, including Phase 3 study commitments in multiple disease areas.

IMBRUVICA® (ibrutinib) was one of the first therapies to receive U.S. approval after having received the FDA’s Breakthrough Therapy Designation. IMBRUVICA works by blocking a specific protein called Bruton’s tyrosine kinase (BTK).1 The BTK protein transmits important signals that tell B cells to mature and produce antibodies and is needed by specific cancer cells to multiply and spread.[5] IMBRUVICA targets and blocks BTK, inhibiting the survival and spread of cancer cells, and impacting signaling associated with other serious conditions.

Hemorrhage: Fatal bleeding events have occurred in patients treated with IMBRUVICA®. Grade 3 or higher bleeding events (intracranial hemorrhage [including subdural hematoma], gastrointestinal bleeding, hematuria, and post-procedural hemorrhage) have occurred in up to 6% of patients. Bleeding events of any grade, including bruising and petechiae, occurred in approximately half of patients treated with IMBRUVICA®.

The mechanism for the bleeding events is not well understood.

IMBRUVICA® may increase the risk of hemorrhage in patients receiving antiplatelet or anticoagulant therapies and patients should be monitored for signs of bleeding.

Consider the benefit-risk of withholding IMBRUVICA® for at least 3 to 7 days pre- and post-surgery depending upon the type of surgery and the risk of bleeding.

Infections: Fatal and non-fatal infections (including bacterial, viral, or fungal) have occurred with IMBRUVICA® therapy. Grade 3 or greater infections occurred in 14% to 29% of patients. Cases of progressive multifocal leukoencephalopathy (PML) and Pneumocystis jirovecii pneumonia (PJP) have occurred in patients treated with IMBRUVICA®. Consider prophylaxis according to standard of care in patients who are at increased risk for opportunistic infections.

Monitor and evaluate patients for fever and infections and treat appropriately.

Cytopenias: Treatment-emergent Grade 3 or 4 cytopenias including neutropenia (range, 13 to 29%), thrombocytopenia (range, 5 to 17%), and anemia (range, 0 to 13%) based on laboratory measurements occurred in patients with B-cell malignancies treated with single agent IMBRUVICA®. Monitor complete blood counts monthly.

Atrial Fibrillation: Atrial fibrillation and atrial flutter (range, 6 to 9%) have occurred in patients treated with IMBRUVICA®, particularly in patients with cardiac risk factors, hypertension, acute infections, and a previous history of atrial fibrillation. Periodically monitor patients clinically for atrial fibrillation. Patients who develop arrhythmic symptoms (e.g., palpitations, lightheadedness) or new onset dyspnea should have an ECG performed. Atrial fibrillation should be managed appropriately, and if it persists, consider the risks and benefits of IMBRUVICA® treatment and follow dose modification guidelines.

Hypertension: Hypertension (range, 6 to 17%) has occurred in patients treated with IMBRUVICA® with a median time to onset of 4.6 months (range, 0.03 to 22 months). Monitor patients for new onset hypertension or hypertension that is not adequately controlled after starting IMBRUVICA®. Adjust existing anti-hypertensive medications and/or initiate anti-hypertensive treatment as appropriate.

Second Primary Malignancies: Other malignancies (range, 3 to 16%) including non-skin carcinomas (range, 1 to 4%) have occurred in patients treated with IMBRUVICA®. The most frequent second primary malignancy was non-melanoma skin cancer (range, 2 to 13%).

Tumor Lysis Syndrome: Tumor lysis syndrome has been infrequently reported with IMBRUVICA® therapy. Assess the baseline risk (e.g., high tumor burden) and take appropriate precautions. Monitor patients closely and treat as appropriate.

Embryo-Fetal Toxicity: Based on findings in animals, IMBRUVICA® can cause fetal harm when administered to a pregnant woman. Advise women to avoid becoming pregnant while taking IMBRUVICA® and for 1 month after cessation of therapy. If this drug is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus. Advise men to avoid fathering a child during the same time period.


B-cell malignancies: The most common adverse reactions (≥20%) in patients with B-cell malignancies (MCL, CLL/SLL, WM and MZL) were thrombocytopenia (62%), neutropenia (61%), diarrhea (43%), anemia (41%), musculoskeletal pain (30%), rash (30%), bruising (30%), nausea (29%), fatigue (29%), hemorrhage (22%), and pyrexia (21%).

The most common Grade 3 or 4 adverse reactions (≥5%) in patients with B-cell malignancies (MCL, CLL/SLL, WM and MZL) were neutropenia (39%), thrombocytopenia (16%), and pneumonia (10%).

Approximately 6% (CLL/SLL), 14% (MCL), 11% (WM) and 10% (MZL) of patients had a dose reduction due to adverse reactions. Approximately 4%-10% (CLL/SLL), 9% (MCL), and 9 % (WM [6%] and MZL [13%]) of patients discontinued due to adverse reactions.

cGVHD: The most common adverse reactions (≥20%) in patients with cGVHD were fatigue (57%), bruising (40%), diarrhea (36%), thrombocytopenia (33%), muscle spasms (29%), stomatitis (29%), nausea (26%), hemorrhage (26%), anemia (24%), and pneumonia (21%).

The most common Grade 3 or 4 adverse reactions (≥5%) reported in patients with cGVHD were fatigue (12%), diarrhea (10%), neutropenia (10%), pneumonia (10%), sepsis (10%), hypokalemia (7%), headache (5%), musculoskeletal pain (5%), and pyrexia (5%).

Twenty-four percent of patients receiving IMBRUVICA® in the cGVHD trial discontinued treatment due to adverse reactions. Adverse reactions leading to dose reduction occurred in 26% of patients.


CYP3A Inducers: Avoid coadministration with strong CYP3A inducers.

CYP3A Inhibitors: Dose adjustment may be recommended.


Hepatic Impairment (based on Child-Pugh criteria): Avoid use of IMBRUVICA® in patients with moderate or severe baseline hepatic impairment. In patients with mild impairment, reduce IMBRUVICA® dose.
