In December 2017, the FDA approved Pfizer’s sBLA (supplemental new drug application) to expand the use of Bosulif to treat adults with newly-diagnosed chronic phase Philadelphia chromosome-positive CML (chronic myelogenous leukemia).
The FDA approval for Bosulif’s label expansion was based on data from the phase 3 BFORE trial. In the phase 3 BFORE trial, a significantly higher rate of patients on Bosulif achieved major molecular response (or MMR) at 12 months—compared to patients on imatinib.
At 12 months, patients on Bosulif had a CCyR (complete cytogenic response) rate of 77.2%—compared to 66.4% for patients on imatinib.
In September 2012, Bosilif received FDA approval to treat adults with chronic accelerated Philadelphia chromosome-positive CML.
Bosulif’s label expansion in December 2017 is expected to boost the drug’s sales in 2018.
In the CML drugs market, Bosulif’s peers include Takeda Pharmaceuticals’ (TKPYY) Iclusig, Bristol-Myers Squibb’s (BMY) Sprycel, and Novartis’s (NVS) Tasigna.
