Eli Lilly (LLY), Bristol-Myers Squibb (BMY) ERBITUX w/ FOLFIRI Granted Full-Approval by FDA

July 9, 2012 6:48 AM EDT
Eli Lilly and Company (NYSE: LLY) and Bristol-Myers Squibb Company (NYSE: BMY) today announced that ERBITUX (cetuximab) in combination with the chemotherapy regimen FOLFIRI (irinotecan, 5-fluorouracil, leucovorin) has been granted full approval by the U.S. Food and Drug Administration (FDA) for the first-line treatment of patients with KRAS mutation-negative (commonly known as KRAS wild-type), epidermal growth factor receptor (EGFR)-expressing metastatic colorectal cancer (mCRC) as determined by FDA-approved tests for this use. ERBITUX is not indicated for the treatment of KRAS mutation-positive colorectal cancer. Concurrently, the FDA also approved the first KRAS companion diagnostic test, the therascreen® KRAS diagnostic kit developed by QIAGEN.

The new indication is based on data from the CRYSTAL (Cetuximab combined with iRinotecan in first-line therapY for metaSTatic colorectAL cancer) trial, a Phase 3 open-label, randomized, multicenter study conducted outside the U.S. that used European Union (EU)-approved cetuximab as the clinical trial material. ERBITUX provides approximately 22 percent higher exposure relative to the EU-approved cetuximab; these pharmacokinetic data, together with the results of this trial and other clinical trial data, establish the efficacy of ERBITUX at the recommended dose in combination with FOLFIRI for first-line KRAS mutation-negative (wild-type) EGFR-expressing mCRC.

With today’s approval, ERBITUX is now the first and only FDA-approved therapy for a specific subset of mCRC patients, targeting those with KRAS mutation-negative (wild-type) tumors. This is based on the positive CRYSTAL study with progression-free survival (PFS) as the primary endpoint in the all randomized patient population treated with EU-approved cetuximab plus FOLFIRI (the CRYSTAL regimen) versus FOLFIRI alone.

The Full Prescribing Information for ERBITUX includes a Boxed WARNING regarding infusion reactions. Serious infusion reactions occurred with the administration of ERBITUX in approximately 3 percent of patients in clinical trials, with fatal outcome reported in less than 1 in 1000. Healthcare providers should immediately interrupt and permanently discontinue ERBITUX infusion for serious infusion reactions.
