In a descriptive analysis, addition of Empliciti to pomalidomide and dexamethasone reduced risk of death by 46% among patients with RRMM
Empliciti-based combination showed improvements across efficacy endpoints, including continued progression-free survival benefit at 18 months
Bristol-Myers Squibb Company (NYSE: BMY) today announced the presentation of updated data from ELOQUENT-3, the international randomized Phase 2 study evaluating Empliciti (elotuzumab) plus pomalidomide and dexamethasone (EPd) versus pomalidomide and dexamethasone (Pd) alone in patients with relapsed or refractory multiple myeloma (RRMM). In a non-prespecified analysis conducted to provide a descriptive assessment of overall survival (OS) after extended follow-up of at least 18.3 months, patients treated with EPd continued to experience sustained and clinically relevant OS and progression-free survival (PFS) benefits compared with patients treated with Pd.
Treatment with EPd was associated with a 46% reduction in risk of death [Hazard Ratio (HR) 0.54; 95% Confidence Interval (CI): 0.30 to 0.96] versus treatment with Pd alone. At 18 months, rates of OS, a secondary endpoint, were 68% for patients treated with EPd compared to 49% for patients treated with Pd. Median OS was not reached with EPd [95% CI: 24.9 months, Not Estimable (NE)] at the time of analysis and was 17.4 months (95% CI: 13.8, NE) among patients receiving Pd. Eighteen-month PFS rates were 34% among patients randomized to EPd compared to 11% among patients randomized to Pd. Safety results for EPd were consistent with the primary analysis and with prior findings for Empliciti and pomalidomide regimens.
These data will be presented at the 24th Congress of the European Hematology Association (EHA) in Amsterdam in a poster display (Abstract #PS1370) on Saturday, June 15 from 5:30-7 PM CEST.
“Multiple myeloma is a disease characterized by relapse, making it all the more important to have effective options available for patients after initial treatments. With 18 months of follow-up from the ELOQUENT-3 trial, we continue to see meaningful improvements across key endpoints with EPd versus Pd alone, including a positive trend in overall survival,” said Meletios A. Dimopoulos, M.D., professor and chairman of the Department of Clinical Therapeutics at Kapodistrian University of Athens School of Medicine. “These data point to the potential for this combination to become a new standard of care for patients with multiple myeloma that returned after or did not respond to prior therapies, including lenalidomide and a proteasome inhibitor.”
“The extended follow-up results from ELOQUENT-3 reinforce the EPd combination’s sustained efficacy and favorable safety profile in patients with relapsed or refractory multiple myeloma,” said Fouad Namouni, M.D., head, Oncology Development, Bristol-Myers Squibb. “These data, along with our overall presence at EHA, underscore our commitment to leading innovative research in hematology and developing therapies that can improve long-term survival for patients with different types of blood cancer.”
Data from the primary analysis of ELOQUENT-3 were published in the New England Journal of Medicine in November 2018 and supported the approval of EPd by the U.S. Food and Drug Administration for the treatment of adult patients with RRMM who have received at least two prior therapies, including lenalidomide and a proteasome inhibitor.
Bristol-Myers Squibb and AbbVie are co-developing Empliciti, with Bristol-Myers Squibb solely responsible for commercial activities.
The Phase 2 ELOQUENT-3 trial randomized 117 patients with RRMM who received two or more prior therapies and were either refractory or relapsed and refractory to lenalidomide and a proteasome inhibitor. Patients were randomized 1:1 to receive either EPd (n=60) or Pd (n=57) in 28-day cycles until disease progression or unacceptable toxicity. Patients in both the EPd and Pd arms received 4 mg of pomalidomide for days 1-21 of each cycle, and the weekly equivalent of 40 mg or 20 mg dexamethasone for patients ≤75 years or >75 years, respectively. In the EPd arm, Empliciti was administered intravenously at the dose of 10 mg/kg weekly for the first 2 cycles and 20 mg/kg every four weeks starting from cycle 3. The primary endpoint of the study was investigator-assessed PFS.
In the 18-month follow-up analysis, adverse events (AEs) were comparable between treatment arms and consistent with the primary analysis. The most common grade 3-4 AEs were infections (22% among patients receiving EPd, 24% among patients receiving Pd), neutropenia (13%, 29%), anemia (10%, 22%), thrombocytopenia (10%, 7%) and hyperglycemia (8%, 11%). Grade 5 all-cause AEs occurred in seven patients (12%) who received EPd and nine patients (16%) who received Pd.
Bristol-Myers Squibb: Advancing Oncology Research
At Bristol-Myers Squibb, patients are at the center of everything we do. The focus of our research is to increase quality, long-term survival for patients and make cure a possibility. Through a unique multidisciplinary approach powered by translational science, we harness our deep scientific experience in oncology and Immuno-Oncology (I-O) research to identify novel treatments tailored to individual patient needs. Our researchers are developing a diverse, purposefully built pipeline designed to target different immune system pathways and address the complex and specific interactions between the tumor, its microenvironment and the immune system. We source innovation internally, and in collaboration with academia, government, advocacy groups and biotechnology companies, to help make the promise of transformational medicines, like I-O, a reality for patients.
Empliciti is an immunostimulatory antibody that specifically targets Signaling Lymphocyte Activation Molecule Family member 7 (SLAMF7), a cell-surface glycoprotein. SLAMF7 is expressed on myeloma cells independent of cytogenetic abnormalities. SLAMF7 also is expressed on Natural Killer cells, plasma cells and at lower levels on specific immune cell subsets of differentiated cells within the hematopoietic lineage.
Empliciti has a dual mechanism of action. It directly activates the immune system through Natural Killer cells via the SLAMF7 pathway. Empliciti also targets SLAMF7 on myeloma cells, tagging these malignant cells for Natural Killer cell-mediated destruction via antibody-dependent cellular toxicity.
Empliciti was initially approved by the FDA in 2015 in combination with lenalidomide and dexamethasone for the treatment of patients with multiple myeloma who have received one to three prior therapies.
U.S. FDA-APPROVED INDICATIONS FOR EMPLICITI®
EMPLICITI® (elotuzumab) is indicated in combination with lenalidomide and dexamethasone for the treatment of adult patients with multiple myeloma who have received one to three prior therapies.
EMPLICITI® (elotuzumab) is indicated in combination with pomalidomide and dexamethasone for the treatment of adult patients with multiple myeloma who have received at least two prior therapies including lenalidomide and a proteasome inhibitor.
IMPORTANT SAFETY INFORMATION
Infusion reactions were reported in 10% of patients treated with EMPLICITI in the ELOQUENT-2 trial [EMPLICITI + lenalidomide + dexamethasone (ERd) vs lenalidomide + dexamethasone (Rd)] and 3.3% in the ELOQUENT-3 trial [EMPLICITI + pomalidomide + dexamethasone (EPd) vs pomalidomide + dexamethasone (Pd)].
In the ELOQUENT-2 trial, all infusion reactions were Grade 3 or lower, with Grade 3 infusion reactions occurring in 1% of patients. The most common symptoms included fever, chills, and hypertension. Bradycardia and hypotension also developed during infusions. In the trial, 5% of patients required interruption of the administration of EMPLICITI for a median of 25 minutes due to infusion reactions, and 1% of patients discontinued due to infusion reactions. Of the patients who experienced an infusion reaction, 70% (23/33) had them during the first dose.
In the ELOQUENT-3 trial, the only infusion reaction symptom was chest discomfort (2%), which was Grade 1. All the patients who experienced an infusion reaction had them during the first treatment cycle.
If a Grade 2 or higher infusion reaction occurs, interrupt the EMPLICITI infusion and institute appropriate medical and supportive measures. If the infusion reaction recurs, stop the EMPLICITI infusion and do not restart it on that day. Severe infusion reactions may require permanent discontinuation of EMPLICITI therapy and emergency treatment.
Premedicate with dexamethasone, H1 blocker, H2 blocker, and acetaminophen prior to EMPLICITI infusion.
In the ELOQUENT-2 trial (N=635), infections were reported in 81% of patients in the ERd arm and 74% in the Rd arm. Grade 3-4 infections were 28% (ERd) and 24% (Rd). Discontinuations due to infections were 3.5% (ERd) and 4.1% (Rd). Fatal infections were 2.5% (ERd) and 2.2% (Rd). Opportunistic infections were reported in 22% (ERd) and 13% (Rd). Fungal infections were 10% (ERd) and 5% (Rd). Herpes zoster was 14% (ERd) and 7% (Rd).
In the ELOQUENT-3 trial (N=115), infections were reported in 65% of patients in both the EPd arm and the Pd arm. Grade 3-4 infections were reported in 13% (EPd) and 22% (Pd). Discontinuations due to infections were 7% (EPd) and 5% (Pd). Fatal infections were 5% (EPd) and 3.6% (Pd). Opportunistic infections were reported in 10% (EPd) and 9% (Pd). Herpes zoster was reported in 5% (EPd) and 1.8% (Pd).
Monitor patients for development of infections and treat promptly.
Second Primary Malignancies
In the ELOQUENT-2 trial (N=635), invasive second primary malignancies (SPM) were 9% (ERd) and 6% (Rd). The rate of hematologic malignancies was the same between ERd and Rd treatment arms (1.6%). Solid tumors were reported in 3.5% (ERd) and 2.2% (Rd). Skin cancer was reported in 4.4% (ERd) and 2.8% (Rd).
In the ELOQUENT-3 trial (N=115), invasive SPMs were 0% (EPd) and 1.8% (Pd).
Monitor patients for the development of SPMs.
In the ELOQUENT-2 trial (N=635), AST/ALT >3X the upper limit, total bilirubin >2X the upper limit, and alkaline phosphatase <2X the upper limit were 2.5% (ERd) vs 0.6% (Rd). Of 8 patients experiencing hepatotoxicity, 2 patients discontinued treatment while 6 patients had resolution and continued. Monitor liver enzymes periodically. Stop EMPLICITI upon ≥Grade 3 elevation of liver enzymes. Continuation of treatment may be considered after return to baseline values.
Interference with Determination of Complete Response
EMPLICITI is a humanized IgG kappa monoclonal antibody that can be detected on both the serum protein electrophoresis and immunofixation assays used for the clinical monitoring of endogenous M-protein. This interference can impact the determination of complete response and possibly relapse from complete response in patients with IgG kappa myeloma protein.
Pregnancy/Females and Males of Reproductive Potential
There are no available data on EMPLICITI use in pregnant women to inform a drug-associated risk of major birth defects and miscarriage.
There is a risk of fetal harm, including severe life-threatening human birth defects, associated with lenalidomide and pomalidomide, and they are contraindicated for use in pregnancy. Refer to the respective product full prescribing information for requirements regarding contraception and the prohibitions against blood and/or sperm donation due to presence and transmission in blood and/or semen and for additional information.
