- In patients treated with elotuzumab 10 mg/kg plus lenalidomide and low-dose dexamethasone, median progression-free survival (PFS) was not reached after 20.8 months of follow up and the objective response rate (ORR) was 92%
- In patients treated with elotuzumab 20 mg/kg plus lenalidomide and low-dose dexamethasone, median PFS was 18.6 months and ORR was 76%
- Safety profile consistent with results previously reported
- Presentation selected for Highlights of ASH
- Two Phase 3 studies of elotuzumab ongoing in patients with newly-diagnosed and previously-treated multiple myeloma
Bristol-Myers
Squibb Company (NYSE: BMY) and Abbott
(NYSE: ABT) today announced results from a small, randomized Phase 2,
open-label study in patients with previously-treated multiple myeloma
that evaluated two doses of elotuzumab (10 mg/kg and 20 mg/kg) in
combination with lenalidomide and low-dose dexamethasone. In the 10
mg/kg arm, median progression-free survival (PFS), or the time without
disease progression or death, was not reached after 20.8 months of
follow up (N=36) and the objective response rate (ORR) was 92%. Of
patients who received elotuzumab at a dose of 20 mg/kg, median PFS was
18.6 months (N=37) and ORR was 76%.
The safety data are consistent with previously-reported results for
elotuzumab. Overall, 78% of patients experienced ≥1 treatment emergent
grade ≥3 events. The most common were lymphopenia (19%), neutropenia
(18%), thrombocytopenia (16%), anemia (12%), leukopenia (10%),
hyperglycemia (10%), pneumonia (7%), diarrhea (7%), fatigue (7%), and
hypokalemia (6%). Two deaths occurred on study (multiple adverse events
[n=1; pneumonia, multiple organ failure and sepsis]; disease progression
[n=1]). Infusion reactions (any grade) were reported in 14% of patients.
Second primary malignancies were reported in four patients and were
deemed as unrelated to elotuzumab.
These results were presented today during an oral session at the 54th
Annual Meeting of the American Society of Hematology (ASH) in Atlanta
and selected for presentation at Highlights of ASH.
“Multiple myeloma is the second most common blood cancer and remains
incurable despite advances in treatment options over the last decade. In
fact, there remains a high unmet medical need for patients, as almost
all will eventually relapse and become refractory to currently available
therapies,” said Paul G. Richardson, M.D. Clinical Director, Jerome
Lipper Center for Multiple Myeloma, Dana-Farber Cancer Institute, lead
author and principal investigator of the study. “The Phase 2 PFS data
for elotuzumab presented today are encouraging and support further
evaluation of this antibody in patients with multiple myeloma as part of
large Phase 3 trials.”
Elotuzumab, an investigational immunotherapy, is a humanized monoclonal
antibody that enhances immune cell mediated killing of multiple myeloma
cells that have a surface protein called CS1. CS1 is a cell-surface
glycoprotein that is highly expressed on myeloma cells.
“The data presented at ASH underscore Bristol-Myers Squibb’s dedication
to seeking advances in care for patients with hematological
malignancies,” said Brian
Daniels, MD, senior vice president, Global Development and Medical
Affairs, Research and Development, Bristol-Myers Squibb. “Elotuzumab,
which is in Phase 3 development for multiple myeloma, is also an example
of our commitment to develop immunotherapies and immuno-oncology
approaches to help address areas of significant unmet medical need in a
broad range of cancers.”
Two Phase 3 studies of elotuzumab in combination with
lenalidomide and low-dose dexamethasone at a dose of 10 mg/kg are
ongoing. The Phase 3 first-line multiple myeloma trial known as
ELOQUENT-1 continues to enroll patients and the Phase 3 trial of
patients with relapsed/refractory multiple myeloma known as ELOQUENT-2
is fully enrolled. A randomized Phase 2 study of bortezomib and
dexamethasone with or without elotuzumab is also ongoing in patients
with relapsed/refractory multiple myeloma.
About the Phase 2 Study
The primary endpoint of this Phase 2, randomized, multicenter,
open-label study was ORR according to the International Myeloma Working
Group (IMWG) response criteria. Patients were randomized 1:1 to receive
elotuzumab either 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), 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.
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 2012, it is estimated that more than
21,700 new cases will be diagnosed in the U.S. and that 10,710 people
will die from the disease.
