Eisai Inc.'s LENVIMA (lenvatinib) Nominated For Galien Foundation’s Best Pharmaceutical Product

WOODCLIFF LAKE, N.J., Oct. 26, 2016 /PRNewswire/ -- Eisai Inc. announced today that LENVIMA^® (lenvatinib), the company's multiple receptor tyrosine kinase inhibitor (TKI), has been nominated for Best Pharmaceutical Product at the 10^th Annual Prix Galien USA Awards Ceremony. The company also received nominations in this category for HALAVEN^® (eribulin mesylate) and BELVIQ^® (lorcaserin HCI) CIV.

"As a science-driven company committed to improving human health care (hhc), we are honored to have our products recognized in a category alongside medicines that have advanced the treatment landscape for cancer and other disease states," said Alton Kremer, MD, PhD, Chief Clinical Officer and Chief Medical Officer, Oncology Business Group at Eisai. "From discovery and development, to continued exploration, we are proud of our ongoing journey with LENVIMA, which has provided an important therapeutic option for patients with two difficult-to-treat cancers."

LENVIMA was first approved by the U.S. Food and Drug Administration (FDA) in February 2015 for patients with locally recurrent or metastatic, progressive, radioactive iodine-refractory differentiated thyroid cancer and has been approved in over 45 countries for the treatment of this disease. Additionally, in May 2016, LENVIMA was also approved in combination with everolimus for the treatment of patients with advanced renal cell carcinoma following one prior anti-angiogenic therapy, making it the first FDA-approved regimen combining a TKI with an mTOR inhibitor for this disease.

HALAVEN, Eisai's synthetic analog of halichondrin B, was first approved in 2010 for the treatment of patients with metastatic breast cancer who have previously received at least two chemotherapeutic regimens for the treatment of metastatic disease. Previous therapy should have included an anthracycline and a taxane either in the adjuvant or metastatic setting. HALAVEN is also approved for the treatment of patients with unresectable or metastatic liposarcoma who have received a prior anthracycline-containing regimen.

BELVIQ, developed by Arena and marketed by Eisai, was approved in 2012 as an adjunct to a reduced-calorie diet and increased physical activity for chronic weight management in adults who have a body mass index (BMI) of 30 kg/m² or greater (obese), or BMI of 27 kg/m² or greater (overweight) with at least one weight-related medical condition such as high blood pressure, high cholesterol, or type 2 diabetes. The safety and efficacy of coadministration of BELVIQ with other products intended for weight loss including prescription drugs, over-the-counter drugs, and herbal preparations have not been established. The effect of BELVIQ on cardiovascular morbidity and mortality has not been established.

All nominees for this coveted award were FDA approved within the last five years, and to qualify, must demonstrate tremendous potential to impact human health. Nine renowned leaders from the biomedical industry and academia, including four Nobel Laureates, will decide the winners of this prestigious award, which will be announced at the 2016 Prix Galien USA Awards Ceremony, held October 27 at the American Museum of Natural History in New York City.

About LENVIMA^® (lenvatinib)
LENVIMA^® (lenvatinib) is a kinase inhibitor that is indicated for:

• Differentiated Thyroid Cancer (DTC): single agent for patients with locally recurrent or metastatic, progressive, radioactive iodine-refractory DTC.
• Renal Cell Cancer (RCC): in combination with everolimus for patients with advanced RCC following one prior anti-angiogenic therapy.

Lenvatinib, discovered and developed by Eisai, is a multiple receptor tyrosine kinase (RTK) inhibitor that inhibits the kinase activities of vascular endothelial growth factor (VEGF) receptors VEGFR1-3. Lenvatinib also inhibits other RTKs that have been implicated in pathogenic angiogenesis, tumor growth, and cancer progression in addition to their normal cellular functions, including fibroblast growth factor (FGF) receptors FGFR1-4; the platelet derived growth factor receptor alpha (PDGFR), KIT, and RET. The combination of lenvatinib and everolimus showed increased anti-angiogenic and anti-tumor activity as demonstrated by decreased human endothelial cell proliferation, tube formation, and VEGF signaling in vitro and tumor volume in mouse xenograft models of human renal cell cancer greater than each drug alone.

Withhold dose for proteinuria 2 g/24 h. Resume at reduced dose when proteinuria is <2 g/24 h. Discontinue for nephrotic syndrome
• In RCC, diarrhea was reported in 81% of patients on LENVIMA + everolimus vs 34% with everolimus alone (19% vs 2% grade 3). Initiate prompt medical management for the development of diarrhea. Monitor for dehydration. Withhold dose for diarrhea grade 3. Resume at a reduced dose when diarrhea resolves to grade 1 or baseline. Discontinue for grade 4 diarrhea despite medical management
• In DTC, events of renal impairment were reported in 14% of patients on LENVIMA vs 2% with placebo (3% vs 1% grade 3). In RCC, events of renal impairment were reported in 18% of patients on LENVIMA + everolimus vs 12% with everolimus alone (10% vs 2% grade 3). Withhold LENVIMA for grade 3 or 4 renal failure/impairment. Resume at reduced dose or discontinue, depending on severity/persistence of renal impairment. Active management of diarrhea and any other gastrointestinal (GI) symptoms should be initiated for grade 1 events
• In DTC, events of GI perforation or fistula were reported in 2% of patients on LENVIMA vs 0.8% with placebo. In RCC, events of GI perforation, abscess, or fistula (grade 3) were reported in 2% of patients on LENVIMA + everolimus vs 0% with everolimus alone. Discontinue in patients who develop GI perforation or life-threatening fistula
• In DTC, QT/QTc interval prolongation was reported in 9% of patients on LENVIMA vs 2% with placebo (2% vs 0% >500 ms). In RCC, QTc interval increases >60 ms were reported in 11% of patients on LENVIMA + everolimus (6% >500 ms) vs 0% with everolimus alone. Monitor electrocardiograms in patients with congenital long QT syndrome, congestive heart failure, bradyarrhythmias, or patients taking drugs known to prolong the QT interval. Monitor and correct electrolyte abnormalities in all patients. Withhold dose for QTc interval prolongation >500 ms. Resume at reduced dose when QTc prolongation resolves to baseline
• In DTC, hypocalcemia (grade 3) was reported in 9% of patients on LENVIMA vs 2% with placebo. In RCC, hypocalcemia (grade 3) was reported in 6% of patients on LENVIMA + everolimus vs 2% with everolimus alone. Monitor blood calcium levels at least monthly and replace calcium as necessary. Interrupt and adjust LENVIMA as necessary
• Across clinical studies in which 1,160 patients received LENVIMA monotherapy, reversible posterior leukoencephalopathy syndrome (RPLS) was reported in 4 patients. Withhold LENVIMA for RPLS until fully resolved. Resume at reduced dose or discontinue based on the severity and persistence of neurologic symptoms
• In DTC, hemorrhagic events occurred in 35% of patients on LENVIMA vs 18% with placebo (2% vs 3% grade 3). The most frequently reported hemorrhagic event was epistaxis (11% grade 1, 1% grade 2). Discontinuation due to hemorrhagic events occurred in 1% of patients on LENVIMA. There was 1 fatal intracranial hemorrhage case among 16 patients who received LENVIMA and had central nervous system metastases at baseline. In RCC, hemorrhagic events occurred in 34% of patients on LENVIMA + everolimus vs 26% with everolimus alone (8% vs 2% grade 3). The most frequently reported hemorrhagic event was epistaxis (23% for LENVIMA + everolimus vs 24% with everolimus alone). There was 1 fatal cerebral hemorrhage case. Discontinuation due to hemorrhagic events occurred in 3% of patients on LENVIMA + everolimus. Consider the risk of severe or fatal hemorrhage associated with tumor invasion/infiltration of major blood vessels (eg, carotid artery). Withhold dose for grade 3 hemorrhage. Resume at reduced dose or discontinue based on severity/persistence of hemorrhage. Discontinue for grade 4 hemorrhage
• In DTC patients with normal baseline thyroid-stimulating hormone (TSH), elevation of TSH level above 0.5 mU/L was observed postbaseline in 57% of patients on LENVIMA vs 14% with placebo. In RCC, grade 1 or 2 hypothyroidism occurred in 24% of patients on LENVIMA + everolimus vs 2% with everolimus alone. In RCC patients with normal or low TSH at baseline, elevation of TSH was observed postbaseline in 60% of patients on LENVIMA + everolimus vs 3% with everolimus alone. Monitor thyroid function prior to treatment initiation and monthly thereafter. Treat hypothyroidism according to standard medical practice to maintain a euthyroid state
• LENVIMA can cause fetal harm when administered to a pregnant woman. Advise females of reproductive potential to use effective contraception during treatment with LENVIMA and for at least 2 weeks following completion of therapy

About HALAVEN^® (eribulin mesylate) Injection
HALAVEN^® (eribulin mesylate) is a microtubule dynamics inhibitor indicated for the treatment of patients with:

• Metastatic breast cancer who have previously received at least two chemotherapeutic regimens for the treatment of metastatic disease. Prior therapy should have included an anthracycline and a taxane in either the adjuvant or metastatic setting.
• Unresectable or metastatic liposarcoma who have received a prior anthracycline- containing regimen.

Discovered and developed by Eisai, eribulin is a synthetic analog of halichondrin B, a natural product that was isolated from the marine sponge Halichondria okadai. First in the halichondrin class, HALAVEN is a microtubule dynamics inhibitor. Eribulin is believed to work primarily via a tubulin-based mechanism that causes prolonged and irreversible mitotic blockage, ultimately leading to apoptotic cell death. Additionally, in preclinical studies of human breast cancer, eribulin demonstrated complex effects on the tumor biology of surviving cancer cells, including increases in vascular perfusion resulting in reduced tumor hypoxia, and changes in the expression of genes in tumor specimens associated with a change in phenotype, promoting the epithelial phenotype, opposing the mesenchymal phenotype. Eribulin has also been shown to decrease the migration and invasiveness of human breast cancer cells.

Warnings and Precautions

• Neutropenia: Severe neutropenia (ANC <500/mm³) lasting >1 week occurred in 12% of patients with mBC and liposarcoma or leiomyosarcoma. Febrile neutropenia occurred in 5% of patients with mBC and 2 patients (0.4%) died from complications. Febrile neutropenia occurred in 0.9% of patients with liposarcoma or leiomyosarcoma, and fatal neutropenic sepsis occurred in 0.9% of patients. Patients with mBC with elevated liver enzymes >3 × ULN and bilirubin >1.5 × ULN experienced a higher incidence of Grade 4 neutropenia and febrile neutropenia than patients with normal levels. Monitor complete blood cell counts prior to each dose, and increase the frequency of monitoring in patients who develop Grade 3 or 4 cytopenias. Delay administration and reduce subsequent doses in patients who experience febrile neutropenia or Grade 4 neutropenia lasting >7 days.
