Applications seek to expand approved use of BOSULIF into first- line treatment based on positive results from Phase 3 head-to-head trial
LONDON, UK & NEW YORK, NY, USA I August 29, 2017 I Pfizer Inc. (NYSE:PFE) and Avillion LLP today announced that a supplemental New Drug Application (sNDA) for BOSULIF® (bosutinib) has been accepted for filing and granted Priority Review by the U.S. Food and Drug Administration (FDA). If approved, the sNDA would expand the approved use of BOSULIF to include patients with newly diagnosed chronic phase Philadelphia chromosome-positive (Ph+) chronic myeloid leukemia (CML). BOSULIF is currently indicated in the U.S. for the treatment of adult patients with Ph+ CML with resistance or intolerance to prior therapy. Priority Review status accelerates FDA review time from 10 months to a goal of six months from the day of acceptance of filing, and is given to drugs that may offer major advances in treatment or may provide a treatment for which no adequate therapy exists. The Prescription Drug User Fee Act (PDUFA) goal date for a decision by the FDA is in December 2017.
In addition, the European Medicines Agency (EMA) has validated for review a Type II Variation application for use of BOSULIF in the same patient population. In Europe, BOSULIF has conditional marketing authorization for the treatment of adult patients with Ph+ CML previously treated with one or more tyrosine kinase inhibitors (TKIs) and for whom imatinib, nilotinib and dasatinib are not considered appropriate treatment options.
The submissions are based on results from BFORE (Bosutinib trial in First line chrOnic myelogenous leukemia tREatment), a multi-center, multinational, open-label Phase 3 study which showed BOSULIF 400 mg was associated with a significantly higher rate of patients achieving major molecular response (MMR) at 12 months (the primary endpoint) compared to the rate achieved in patients treated with imatinib. Results from the trial were presented at the American Society of Clinical Oncology (ASCO) Annual Meeting in May 2017 and at the European Hematology Association (EHA) Meeting in June 2017. The adverse events seen in the trial were consistent with the known safety profile for BOSULIF. The proposed dosing for the newly diagnosed patients is 400 mg daily, which is different from the currently approved dosing in patients who are resistant or intolerant to prior TKI therapy (500 mg daily).
“As physicians gained experience with BOSULIF, they have come to appreciate its favorable risk-benefit profile in patients with Ph-positive CML who no longer responded to or could not tolerate prior TKI therapy,” said Mace Rothenberg, MD, Chief Development Officer, Oncology, Pfizer Global Product Development. “At the 400 mg dose, we believe that the BFORE study demonstrates a similarly favorable risk-benefit in previously untreated patients with Ph-positive CML. We look forward to working with the FDA in our efforts to expand the label for BOSULIF to include this important group of patients.”
“These are important milestones for the CML community and for our partnership with Pfizer, which represent the commitment of both of our companies to work collaboratively toward our ultimate goal of improving the lives of patients,” said Allison Jeynes-Ellis, MD, Chief Executive Officer of Avillion.
Pfizer and Avillion entered into an exclusive collaborative development agreement in 2014 to conduct the BFORE trial. Under the terms of the agreement, Avillion provided funding and conducted the trial to generate the clinical data used to support these applications and other potential regulatory filings for marketing authorization for BOSULIF as first-line treatment for patients with chronic phase Ph+ CML. If approved for this indication, Avillion will be eligible to receive milestone payments from Pfizer. Pfizer retains all rights to commercialize BOSULIF globally.
Pfizer is advancing a broad range of therapies that leverage select pathways and mechanisms of action to address acute and chronic leukemias, myeloproliferative disorders and lymphoma.
ABOUT CHRONIC MYELOID LEUKEMIA (CML)
Chronic myeloid leukemia (CML) is a rare blood cancer, which begins in the bone marrow, but often moves into the blood.1 Researchers estimate that by 2020, more than 412,000 people worldwide will be diagnosed with leukemia (all types).2 CML accounts for 10-15% of all incident leukemia cases.1,3 In the U.S., approximately 48,000 people are living with CML.4 Around 9,000 new CML cases will be diagnosed in the U.S. in 2017.5
ABOUT BOSULIF® (bosutinib)
BOSULIF® (bosutinib) is an oral, once-daily, tyrosine kinase inhibitor (TKI), which inhibits the Bcr-Abl kinase that promotes CML; it is also an inhibitor of Src-family kinases. BOSULIF was approved in September 2012 in the U.S. for the treatment of adult patients with Ph+ CML with resistance or intolerance to prior therapy and offers an important treatment option for these patients. In Europe, BOSULIF was granted conditional marketing authorization in March 2013 for the treatment of adult patients with Ph+ CML previously treated with one or more TKIs and for whom imatinib, nilotinib and dasatinib are not considered appropriate treatment options. The current approved dose of BOSULIF is 500 mg orally once daily with food.
