"AbbVie delivered strong performance in 2015, exceeding original sales, margin expansion, and earnings projections for the year," said Richard A. Gonzalez, chairman and chief executive officer, AbbVie. "We achieved significant growth in 2015, and expect to continue building on that momentum in 2016 with another year of strong performance."

Fourth-Quarter Results

Worldwide adjusted net revenues were $6.360 billion in the fourth-quarter, up 18.4 percent. On an operational basis, adjusted net revenues increased 24.4 percent, excluding a 6.0 percent unfavorable impact from foreign exchange rate fluctuations.

Global HUMIRA sales increased 16.0 percent on an operational basis, excluding the impact of foreign exchange. Exceptional U.S. HUMIRA growth of 20.7 percent was driven by continued momentum across all three major market categories – rheumatology, dermatology and gastroenterology. International HUMIRA sales growth was also strong in the fourth quarter, up 9.7 percent on an operational basis. Reported international HUMIRA sales growth in the quarter was reduced by 13.1 percent due to unfavorable foreign exchange.

Fourth-quarter global IMBRUVICA net revenue was $343 million, with U.S. sales of $295 million and international profit sharing of $48 million for the quarter.

Total company revenue growth was also driven by $554 million in global VIEKIRA sales in the quarter, as well as strong operational growth from Duodopa, Creon and Lupron.

Adjusted gross margin ratio in the fourth quarter was 80.5 percent, excluding intangible asset amortization and other specified items. On a GAAP basis, the gross margin ratio was 77.0 percent.

Adjusted selling, general and administrative (SG&A) expense was 23.9 percent of net revenues in the fourth quarter. On a GAAP basis, SG&A was 27.1 percent of net revenues.

Adjusted research and development (R&D) expense was 15.9 percent of net revenues in the quarter, reflecting funding actions in support of our mid- and late-stage pipeline. On a GAAP basis, R&D was 16.8 percent of net revenues.

Adjusted operating margin in the fourth quarter was 40.1 percent, compared to 35.8 percent in fourth-quarter 2014. On a GAAP basis, the operating margin was 33.0 percent.

Net interest expense was $199 million. The adjusted tax rate in the quarter was 21.6 percent and 21.1 percent on a GAAP basis.

Adjusted diluted earnings per share, excluding intangible asset amortization expense and other specified items, were $1.13 in the fourth quarter, up 27 percent. Diluted earnings per share were $0.92 on a GAAP basis.

Key Events from the Fourth Quarter

AbbVie submitted a supplemental New Drug Application (sNDA) for ibrutinib (IMBRUVICA) to the U.S. Food and Drug Administration (FDA) for use in treatment-naïve chronic lymphocytic leukemia (CLL) patients, based on results from the Phase 3 RESONATE-2 study. These data, published in The New England Journal of Medicine (NEJM), found that IMBRUVICA significantly decreased the risk of progression or death (progression-free survival, PFS) and significantly decreased the risk of death (overall survival, OS) versus chlorambucil in treatment-naïve patients 65 years and older with CLL.

AbbVie submitted a New Drug Application (NDA) and a Marketing Authorization Application (MAA) for venetoclax in patients with relapsed/refractory (R/R) CLL in patients with chromosome 17p deletion to the FDA and European Medicines Agency (EMA), respectively. Priority review status was granted by the FDA and validation provided by the EMA for these submissions based on results from a Phase 2, open-label trial that found treatment with venetoclax demonstrated a 79.4 percent overall response rate (ORR) as monotherapy treatment, including patients that achieved complete remission.

AbbVie has now received three FDA Breakthrough Therapy Designations for venetoclax. The first designation was received early last year for the treatment of patients with R/R CLL with chromosome 17p deletion. The second designation for venetoclax was received earlier this month for combination therapy with rituximab for patients with R/R CLL, including those with chromosome 17p deletion. A third designation was received this week for venetoclax in combination with hypomethylating agents (HMAs) in patients with untreated (treatment-naïve) acute myeloid leukemia (AML) who are ineligible to receive standard induction therapy (high-dose chemotherapy).

AbbVie submitted a sNDA to the FDA for labeling considerations based on safety and efficacy results from the Phase 3 HELIOS trial of IMBRUVICA in patients with R/R CLL. The trial found that treatment with IMBRUVICA plus bendamustine and rituximab, versus placebo plus rituximab, significantly reduced the risk of disease progression or death by 80 percent and significantly improved ORR compared to placebo plus rituximab in previously-treated CLL/SLL patients.

The FDA accepted AbbVie’s sNDA and granted priority review for VIEKIRA PAK without ribavirin in patients with genotype 1b (GT1b) chronic hepatitis C virus infection (HCV) and compensated cirrhosis (Child-Pugh A). The application was supported by data from the TURQUOISE-III study, which showed 100 percent sustained virologic response at 12 weeks post-treatment (SVR12) in this patient population.

AbbVie announced that the FDA accepted its NDA for a once-daily, fixed-dosed formulation of VIEKIRA PAK to treat GT1 HCV. The proposed dosing for the fixed-dose formulation is three oral tablets, taken once daily with a meal, with or without ribavirin. AbbVie anticipates regulatory action on the new formulation in 2016.

At the American Society of Hematology (ASH) (Free ASH Whitepaper)’s Annual Meeting (ASH) (Free ASH Whitepaper) in December 2015, AbbVie presented new results from a Phase 2, open-label study of venetoclax in treatment-naïve patients 65 years and older with AML who were not eligible for intensive-induction chemotherapy. These data found that combination treatment with venetoclax and hypomethylating agents resulted in complete response rates of approximately 71 percent, which is roughly double the response rate that would be expected with current standard of care treatment. AbbVie plans to initiate registration studies of venetoclax for this indication in 2016.

AbbVie’s IMBRUVICA partner Janssen presented results from the Phase 3 RAY study which demonstrated treatment with IMBRUVICA significantly prolonged PFS and improved ORR in patients with R/R mantle-cell lymphoma (MCL), compared with temsirolimus. Specifically, IMBRUVICA was found to reduce the risk of disease progression or death by 57 percent with a median follow-up of 20 months. These data were also published online in The Lancet.

AbbVie announced that data from a Phase 2 study evaluating IMBRUVICA therapy in treatment-naïve patients with follicular lymphoma (FL) demonstrated that a combination of IMBRUVICA and rituximab was well-tolerated and associated with ORR of 82 percent.

AbbVie presented data from its next-generation HCV regimen (ABT-493 and ABT-530) being evaluated as a pan-genotypic, once-daily treatment option for patients with HCV at the 2015 Annual Meeting of the American Association for the Study of Liver Diseases (AASLD). Results demonstrated 12 weeks of treatment resulted in 97-100 percent SVR12 in GT1 non-cirrhotic HCV, 96-100 percent in genotype (GT2) and 83-94 percent in genotype 3 (GT3) patients. Additionally, data from the SURVEYOR-I study were also presented at the meeting and showed that non-cirrhotic GT1 HCV patients who received shorter duration of treatment for 8 weeks with ABT-493 and ABT-530 achieved SVR12 rates of 97 percent. The company initiated Phase 3 studies in the fourth quarter of 2015.

At the American College of Rheumatology (ACR) Annual Meeting, AbbVie presented the full 12-week, Phase 2b safety data for ABT-494, an investigational oral JAK-1 inhibitor, from the BALANCE-I study (efficacy data was previously top-lined). This study evaluated a broad dose range to understand the boundaries of JAK-1 selectivity and the efficacy of ABT-494 versus placebo in previously treated patients with rheumatoid arthritis (RA) with persistent and active disease. The study met its primary endpoint, achieving an ACR20 response after 12 weeks of treatment using an LOCF approach, and ACR20 for all dose levels. The BALANCE I and II results support the company’s decision to move ABT-494 into Phase 3 studies with a once-daily dose. The Phase 3 program was initiated in late 2015 and a Phase 2 trial of ABT-494 is ongoing for the treatment of Crohn’s disease.

The FDA approved Empliciti (elotuzumab) for the treatment of multiple myeloma (MM) as a combination therapy in patients who have received one to three prior therapies. Empliciti was co-developed by AbbVie and Bristol-Myers Squibb (BMS) and will be marketed by BMS. This approval was based on data from a Phase 3 study which demonstrated that patients treated with Empliciti plus standard of care therapy achieved a 30 percent reduction in the risk of disease progression or death compared to standard of care alone. This is the first FDA approval for an immune-stimulatory antibody for MM in this indication.

Confirming Full-Year 2016 Outlook

AbbVie is confirming its diluted earnings-per-share guidance of $4.90 to $5.10 on an adjusted basis for the full-year 2016, representing strong double-digit growth versus 2015 and positioning AbbVie to be among the industry leaders for growth again in 2016. The company’s 2016 adjusted diluted earnings-per-share guidance excludes $0.45 per share of intangible asset amortization expense and other specified items. Including these items, AbbVie’s diluted earnings-per-share guidance is $4.45 to $4.65 on a GAAP basis.

U.S. FDA APPROVES EISAI’S ANTICANCER AGENT HALAVEN(R) FOR THE TREATMENT OF ADVANCED LIPOSARCOMA

On January 29, 2016 Eisai Co., Ltd. (Headquarters: Tokyo, CEO: Haruo Naito, "Eisai") reported that its U.S. subsidiary Eisai Inc. has received approval from the U.S. Food and Drug Administration (FDA) of its in-house developed anticancer agent Halaven (eribulin mesylate) for the treatment of patients with unresectable or metastatic liposarcoma who have received a prior anthracycline-containing regimen (Press release, Eisai, JAN 29, 2016, View Source [SID:1234508906]). Halaven is the first and only single agent to demonstrate an overall survival (OS) benefit in a Phase III trial in patients with advanced or recurrent and metastatic soft tissue sarcoma (leiomyosarcoma or liposarcoma). Following approval for use in the treatment of metastatic breast cancer in the United States, this marks the second indication for which Halaven has been approved by the FDA based on a statistically significant extension of OS.

This approval was based on the results from a multicenter, open-label, randomized Phase III study (Study 309) comparing the efficacy and safety of Halaven versus dacarbazine in 452 patients (aged 18 or over) with locally advanced or recurrent and metastatic soft tissue sarcoma (liposarcoma or leiomyosarcoma) who had disease progression following standard therapies which must have included an anthracycline and at least one other additional regimen.

Halaven demonstrated a statistically significant extension in the study’s primary endpoint of OS over the comparator treatment dacarbazine (Halaven median OS: 13.5 months vs dacarbazine median OS: 11.5 months; Hazard Ratio (HR) 0.768 [95% CI=0.618-0.954], p=0.017).1
For patients with liposarcoma, Halaven demonstrated a significant improvement in OS over dacarbazine (Halaven, n=71, median OS: 15.6 months vs dacarbazine, n=72, median OS: 8.4 months; HR 0.51 [95% CI=0.35-0.75]).2 Additionally, in the study’s secondary endpoint of progression-free survival (PFS), patients treated with Halaven experienced an improvement in PFS over dacarbazine (Halaven median PFS: 2.9 months vs dacarbazine median PFS: 1.7 months; HR 0.52 [95% CI=0.35-0.78]).2

The most common adverse reactions (incidence greater than or equal to 25%) in study patients with liposarcoma and leiomyosarcoma treated with Halaven were fatigue, nausea, alopecia, constipation, peripheral neuropathy, abdominal pain and pyrexia, which was consistent with the known side-effect profile of Halaven.2 The most common (incidence greater than or equal to 5%) Grade 3-4 laboratory abnormalities reported in patients receiving Halaven were neutropenia, hypokalemia, and hypocalcemia. The most common serious adverse reactions reported in patients receiving Halaven were neutropenia (4.9%) and pyrexia (4.5%).2

Soft tissue sarcoma is a collective term for a diverse group of malignant tumors that occur throughout the soft tissues (fat, muscle, nerves, fibrous tissues and blood vessels) in the body. Approximately 12,000 patients in the United States are diagnosed with soft tissue sarcoma each year, and liposarcoma is one of the most common forms of soft tissue sarcoma. As outcomes are poor for patients with advanced disease, it remains a disease with significant unmet medical need.

Applications seeking approval of Halaven for use in the treatment of soft tissue sarcoma have been submitted in Europe and Japan. Meanwhile, the agent has been designated as an orphan drug for the treatment of soft tissue sarcoma in the United States and Japan.

Halaven is a halichondrin class microtubule dynamics inhibitor with a distinct binding profile.2 In addition, recent non-clinical studies showed that Halaven is associated with increased vascular perfusion and permeability in tumor cores.3 Halaven promotes the epithelial state and decreases the capacity of breast cancer cells to migrate.4 It was first approved in the United States in November 2010 for patients with metastatic breast cancer who have 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. Halaven is currently approved for use in the treatment of breast cancer in approximately 60 countries including Japan and countries in Europe, the Americas and Asia.

Through this additional approval, Eisai remains committed to providing further clinical evidence for Halaven aimed at maximizing value of the drug as it seeks to contribute further to addressing the diverse needs of, and increasing the benefits provided to, patients with cancer, their families, and healthcare providers.

1. About Halaven (eribulin mesylate)
Halaven is the first in the halichondrin class of microtubule dynamics inhibitors with a novel mechanism of action. Structurally Halaven is a simplified and synthetically produced version of halichondrin B, a natural product isolated from the marine sponge Halichondria okadai. Halaven is believed to work by inhibiting the growth phase of microtubule dynamics which prevents cell division. In addition, recent non-clinical studies showed that Halaven is associated with increased vascular perfusion and permeability in tumor cores.3 Halaven promotes the epithelial state and decreases the capacity of breast cancer cells to migrate.4
Halaven was first approved as a treatment in the United States in November 2010 for patients with metastatic breast cancer who have 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. Halaven is currently approved for use in the treatment of breast cancer in approximately 60 countries worldwide, including Japan and countries in the Europe, Americas and Asia. In Japan, Halaven has been approved to treat inoperable or recurrent breast cancer and was launched in the country in July 2011. Halaven has also been approved in countries in Europe and Asia indicated as a treatment for patients with locally advanced or metastatic breast cancer who have progressed after at least one chemotherapeutic regimen for advanced disease. Prior therapy should have included an anthracycline and a taxane in either the adjuvant or metastatic setting, unless patients were not suitable for these treatments.
Regarding soft tissue sarcoma, Halaven has been approved in the United States for the treatment of patients with unresectable or metastatic liposarcoma who have received a prior anthracycline-containing regimen, and applications seeking approval for this potential indication have been submitted in Japan and Europe. Meanwhile, Halaven has been designated as an orphan drug for soft-tissue sarcoma in the United States and Japan.

2. About Soft Tissue Sarcoma
Soft tissue sarcoma is a collective term for a diverse group of malignant tumors that occur throughout the soft tissue (fat, muscle, nerves, fibrous tissues and blood vessels) in the body. Approximately 12,000 patients in the United States and 29,000 patients in Europe are diagnosed with soft tissue sarcoma each year. According to a patient survey conducted by Japan’s Ministry of Health, Labour and Welfare, there are approximately 4,000 patients with soft tissue sarcoma in Japan. As the structures where the tumors originate are diverse, there are various types of soft tissue sarcoma, and the most common types include leiomyosarcoma, liposarcoma and malignant fibrous histiocytoma. While treatment of soft tissue sarcoma is focused on curative surgery, if the degree of malignancy is high, treatment then becomes a combination of chemotherapy and radiation therapy. As outcomes are poor for patients with advanced disease, it remains a disease with significant unmet medical need.

3. About Study 309
Conducted primarily in Europe and the United States, Study 309 was a multicenter, open-label, randomized Phase III study comparing the efficacy and safety of Halaven versus dacarbazine in 452 patients (aged 18 or over) with locally advanced or recurrent and metastatic soft tissue sarcoma (liposarcoma or leiomyosarcoma) who had disease progression following standard therapies which must have included an anthracycline and at least one other additional regimen. Patients received either Halaven (1.4 mg/m2 administered intravenously on Day 1 and Day 8) or dacarbazine (850–1200 mg/m2 administered intravenously on Day 1) every 21 days until disease progression.
From the results for the study, Halaven demonstrated a statistically significant extension in the study’s primary endpoint of overall survival (OS) over the comparator treatment dacarbazine (Halaven median OS: 13.5 months vs dacarbazine median OS: 11.5 months; Hazard Ratio (HR) 0.768 [95% CI=0.618-0.954], p=0.017).1 Furthermore, in the study’s secondary endpoints, there was no statistically significant difference found between Halaven and dacarbazine in either progression-free survival (PFS) (median PFS: 2.6 months in both arms) or progression-free rate at 12 weeks (PFR12wks) (Halaven PFR12wks: 33% vs dacarbazine PFR12wks: 29%).1
For patients with liposarcoma, Halaven demonstrated a statistically significant improvement in OS over dacarbazine (Halaven, n=71, median OS: 15.6 months vs dacarbazine, n=72, median OS: 8.4 months; HR 0.51 [95% CI=0.35-0.75]).2 Additionally, patients treated with Halaven experienced an improvement in PFS over dacarbazine (Halaven median PFS: 2.9 months vs dacarbazine median PFS: 1.7 months; HR 0.52 [95% CI=0.35-0.78]).2
The most common adverse reactions (incidence greater than or equal to 25%) in study patients with liposarcoma and leiomyosarcoma treated with Halaven were fatigue (62%), nausea (41%), alopecia (35%), constipation (32%), peripheral neuropathy (29%), abdominal pain (29%) and pyrexia (28%), which was consistent with the known side-effect profile of Halaven.2 The most common (incidence greater than or equal to 5%) Grade 3-4 laboratory abnormalities reported in patients receiving Halaven were neutropenia (32% vs. 8.9% in the dacarbazine arm), hypokalemia (5.4% vs. 2.8%) and hypocalcemia (5.0% vs. 1.4%). The most common serious adverse reactions reported in patients receiving Halaven were neutropenia (4.9%) and pyrexia (4.5%).2 The most common adverse reactions resulting in discontinuation of Halaven were fatigue and thrombocytopenia (0.9% each).
