• Median progression-free survival (PFS) of 33 months reached after longer-term follow up in patients treated with elotuzumab 10 mg/kg plus lenalidomide and low-dose dexamethasone
  • Longer-term safety profile of the combination consistent with previously reported results
  • Results Presented at 18th Annual Congress of the European Hematology Association
  • Two Phase 3 studies of elotuzumab at 10 mg/kg dose ongoing in patients with previously-treated and newly-diagnosed multiple myeloma

PRINCETON, NJ & NORTH CHICAGO, IL, USA I June 15, 2013 I Bristol-Myers Squibb Company (BMY) and AbbVie (ABBV) today announced updated efficacy and safety data from a small, randomized Phase 2, open-label study in patients with previously-treated multiple myeloma that evaluated two doses of the investigational monoclonal antibody elotuzumab (10 mg/kg and 20 mg/kg) in combination with lenalidomide and low-dose dexamethasone. In the 10 mg/kg arm (N=36), which is the dose used in the ongoing Phase 3 trials, median progression-free survival (PFS), or the time without disease progression, was 33 months after a median follow-up of 20.8 months (95% CI: 14.9-NA) and the objective response rate (ORR) was 92%. As previously reported, median PFS was 18 months in the 20 mg/kg arm (N=37) after a median follow-up of 17.1 months (95% CI: 12.912-32.361) and ORR was 76%.

 The safety data were consistent with previously-reported results for elotuzumab from this trial. In patients receiving elotuzumab 10 mg/kg or 20 mg/kg, most treatment-emergent adverse events occurred within 18 months of initiating therapy. The most common Grade 3/4 adverse events (seen in > 5% of patients) for the 10 mg/kg and 20 mg/kg arms respectively were lymphopenia (26% and 9%), neutropenia (21% and 22%), thrombocytopenia (21% and 17%), anemia (13% and 12%), leukopenia (8% and 7%), hyperglycemia (5% and 12%), pneumonia (8% and 5%), diarrhea (10% and 5 %), fatigue (8% and 9%), and hypokalemia (8% and 5%). As previously reported at the 2012 American Society of Hematology annual meeting, two deaths occurred on study (multiple adverse events [n=1; pneumonia, multiple organ failure and sepsis]). 

These data were presented today at the 18th Annual Congress of the European Hematology Association (EHA) in Stockholm, Sweden. (Abstract #14) 

 “There remains a high unmet medical need for patients with multiple myeloma, the second most common blood cancer, as many may relapse and stop responding to currently available treatments,” said Thierry Facon, MD, Hospital Claude Huriez, Service des Maladies du Sang, Lille, France. “The Phase 2 data on elotuzumab are encouraging and support further evaluation in Phase 3 trials.” 

About the Phase 2 Study

 In the phase 2 study, patients with relapsed/refractory multiple myeloma were randomized 1:1 to receive elotuzumab 10 or 20 mg/kg (IV infusion on days 1, 8, 15, and 22 of a 28-day cycle in the first 2 cycles and then days 1 and 15 of subsequent cycles) in combination with lenalidomide 25 mg PO daily on days 1 to 21 and dexamethasone 40 mg PO weekly. Patients were treated until disease progression or unacceptable toxicity, if earlier. Objective response rate was the study’s primary endpoint per response criteria established by the International Myeloma Working Group. Secondary endpoints in the trial include PFS and safety. 

About Elotuzumab

 Elotuzumab, an investigational compound in Phase 3 development, is a humanized monoclonal antibody that targets a cell-surface protein called CS1 that is highly expressed on multiple myeloma cells. 

 Studies of elotuzumab in combination with lenalidomide and low-dose dexamethasone at a dose of 10 mg/kg are ongoing. ELOQUENT-1, a Phase 3 trial in first-line multiple myeloma trial is currently enrolling patients and a second Phase 3 trial of patients with relapsed/refractory multiple myeloma (ELOQUENT-2) is fully enrolled. Elotuzumab is also being investigated in a randomized Phase 2 study of bortezomib and dexamethasone with or without elotuzumab in relapsed or refractory multiple myeloma. 

About Multiple Myeloma

Multiple myeloma is a type of cancer that originates in the white blood cells. It is the second most common blood cancer with an annual incidence of more than 100,000 worldwide and a 5-year survival rate of 41% in newly-diagnosed patients. In 2013, it is estimated that approximately 22, 350 new cases will be diagnosed in the U.S. and that 10,710 people will die from the disease.
