Albiglutide consists of a GLP-1 peptide fused to albumin. The GLP-1 peptide helps to maintain normal blood glucose levels, and the albumin component allows for once weekly subcutaneous dosing. If approved, albiglutide would be the fourth GLP-1 agonist to the market. Other currently approved GLP-1 agonists include once-daily Victoza® (liraglutide), twice-daily Byetta® (exenatide), and once-weekly Bydureon® (exenatide).1 The Harmony clinical program evaluated the efficacy and safety of albiglutide.2,3 In Harmony 3, the reduction in hemoglobin A1C (HbA1c) was statistically significant in the albiglutide group compared to those treated with Januvia® (sitagliptin) (p = 0.0001) or glimepiride (p = 0.003). In Harmony 4 and 6, albiglutide was non-inferior to Lantus® (insulin glargine) [95% confidence interval (CI): 0.04-0.27%] and Humalog® (insulin lispro) (p < 0.0001). In Harmony 5 and 7, non-inferiority was not achieved when albiglutide was compared to pioglitazone (p = 0.27) and Victoza (p = 0.0846), respectively.4 Unlike Bydureon, which requires reconstitution prior to administration, Eperzan will be available as pen devices. The United States Food and Drug Administration (FDA) is expected to make a decision regarding the approval of Eperzan by April 15, 2014.5 If approved, analysts estimate that annual sales of Eperzan will be approximately $440 million by 2018.6 TBD (apremilast) Apremilast, a NME, is an oral phosphodiesterase-4 inhibitor being developed by Celgene for the treatment of adult patients with active psoriatic arthritis (PsA). Apremilast works intracellularly to modulate a network of pro-inflammatory and anti-inflammatory mediators.7 It is estimated that approximately 30% of people with psoriasis is affected by PsA.7 Currently, the treatment options for PsA include injectable biologics [eg, tumor necrosis factor-alpha (TNFα) inhibitors], following patients who have not responded to disease-modifying antirheumatic drugs (DMARDS).7 In the PALACE-1,2,3 phase III clinical trials, the efficacy and safety of apremilast were evaluated in patients with active PsA despite treatment with DMARDS and TNFα inhibitors. Results showed that apremilast demonstrated statistical significance in achieving American College of Rheumatology (ACR) 20 score when compared to placebo.7 PALACE-4, a study evaluating the use of apremilast in treatment-naïve PsA patients, showed that ACR20 response was achieved in 29.2-32.3% and 16.9% of patients in the apremilast and placebo groups, respectively.8 A pooled safety data analysis showed no safety concerns with regards to major cardiac events, malignancies, and reactivation of tuberculosis.7 The FDA is expected to make a decision regarding the approval of apremilast by March 2014.5 Celgene estimates that apremilast annual sales will generate between $1.5-2 billion by 2017.9 Ruconest® (recombinant human C1 esterase inhibitor) Ruconest, a NME with orphan drug status, is a recombinant human complement 1 (C1) esterase inhibitor that is being developed by Pharming Group NV and Salix Pharmaceuticals for the treatment of acute hereditary angioedema attacks in patients with hereditary angioedema (HAE). HAE is a genetic disorder in which the patient is deficient in or lacks a functional plasma protein C1 inhibitor, resulting in episodes of intense swelling of the extremities, face, trunk, genitals, abdomen, and upper airway.10 The efficacy and safety of Ruconest were evaluated in two randomized placebo-controlled clinical studies.11 Both studies showed statistically significant reductions in time to onset of HAE symptom relief with Ruconest (50 U/ kg: 122 minutes [95% CI: 72-136]; 100 U/kg: 66 minutes [95% CI: 0.08-0.34]) compared to placebo (495 OptumRx | optumrx.com 3 of 8 OptumRx Pipeline Forecast 1st Quarter 2014 minutes [95% CI: 245-520]). Post-exposure antibody responses against Ruconest or host-related impurities were not observed. Ruconest is unique among other C1 esterase inhibitor replacement products (eg, Berinert®) because it is produced from transgenic rabbits rather than derived from human plasma donors.1,12 Thus, the concern for infectious transmissions with Ruconest use is limited. The FDA is expected to make a decision regarding the approval of Ruconest by July 16, 2014.13 TBD (empagliflozin) Empagliflozin, a NME, is an oral sodium glucose co-transporter 2 (SGLT2) inhibitor being developed by Boehringer Ingelheim and Eli Lilly for the treatment of adults with type 2 diabetes mellitus. If approved, empagliflozin would be the third SGLT2 inhibitor on the market since the approval of Invokana™ (canagliflozin) and Farxiga® (dapagliflozin).1 In clinical trials, empagliflozin 10 mg and 25 mg showed mean reductions in HbA1c as both monotherapy and add-on treatment; HbA1c reductions ranged from -0.62% to -0.68% for 10 mg and 25 mg, respectively.14 When empagliflozin monotherapy was compared to Januvia® (sitagliptin), the adjusted mean differences in change from baseline for HbA1c were -0.74% (p < 0.0001) for empagliflozin 10 mg, -0.85% (p < 0.0001) for empagliflozin 25 mg, and -0.73% (p < 0.0001) for Januvia.15 In a pooled analysis of clinical trials, there was a loss of 3.99 to 4.43 pounds in body weight for empagliflozin compared to placebo.14 Although the incidence of urinary tract infections in empagliflozin-treated patients was comparable to placebo, the incidence of genital infections (3.6-4.2%) was higher than placebo (0.7%).14 The FDA is expected to make a decision regarding the approval of empagliflozin by March 25, 2014.5 If approved, analysts estimate that empagliflozin will have a market share of about 3%, or $1.6 billion, by 2017.16 Afrezza® (insulin monomer human [rDNA origin]) Afrezza is an inhaled ultra rapid-acting mealtime insulin therapy being developed by MannKind for the treatment of adults with type 1 or type 2 diabetes mellitus for control of hyperglycemia. It is a drug-device combination product, consisting of an Afrezza inhalation powder single-use cartridge and a small inhaler. Afrezza strives to mimic the release of mealtime insulin observed in healthy individuals, with time to peak insulin levels at 12 to 15 minutes following administration.17 The phase III clinical program demonstrated that Afrezza was non-inferior to Novolog® (insulin aspart) for HbA1c reduction. In addition, patients treated with Afrezza experienced significantly fewer hypoglycemia episodes and less weight gain than Novologtreated patients.17,18 The most common respiratory side effect observed with Afrezza use in clinical trials was a mild, transient, non-productive cough. Lung function changes were small and resolved once Afrezza was discontinued.17 The FDA Endocrinologic and Metabolic Drugs Advisory Committee is scheduled to discuss Afrezza on April 1, 2014.19 The FDA is expected to make a decision regarding its approval by April 15, 2014.5 Ragwitek™ (ragweed pollen extract) Ragwitek, a short ragweed (Ambrosia artemisiifolia) pollen allergen extract, is an oral immunotherapy. It is being developed by Merck and ALK-Abelló A/S for the prevention of ragweed pollen-induced allergic rhinitis, with or without conjunctivitis, in persons 18-65 years of age. Currently, allergen extracts are only FDA-approved for use in subcutaneous allergen immunotherapy. Ragwitek is a sublingual, once-daily administered tablet that is given at least 12 weeks prior to the onset of grass pollen season, and to be continued through the season.20 Clinical trials measured a combined symptom and medication use score over the course of a pollen season. Ragwitek demonstrated a 24-26% improvement in the combined OptumRx | optumrx.com 4 of 8 OptumRx Pipeline Forecast 1st Quarter 2014 symptom score during the ragweed pollen season compared to placebo.20 Common adverse events with Ragwitek use included itching and swelling in and around the mouth.20 The FDA’s Allergic Products Advisory Committee voted 6-2, with one abstention, in support of Ragwitek’s efficacy. However, the Committee also recommended post-marketing trials targeted at unstudied or under-studied populations, and rare adverse events seen in the clinical program.21 The FDA is expected to make its decision regarding the approval of Ragwitek by March 2014.5 TBD (ramucirumab) Ramucirumab, a NME with orphan drug status, is a human, receptor-targeted antibody that blocks the vascular endothelial growth factor (VEGF) receptor 2. It is being developed by Eli Lilly as a single-agent treatment of advanced gastric cancer following disease progression after initial chemotherapy. Currently, ramucirumab is also being investigated for use in colorectal, hepatocellular, and lung cancers.22 If approved, ramucirumab will be the first FDA-approved second-line therapy for advanced cancers of the esophagus and stomach. In the REGARD study, median overall survival was 5.2 months in the ramucirumab group and 3.8 months in the placebo group (p = 0.047). In addition, hypertension rates observed in REGARD were higher in the ramucirumab group (16%) compared to the placebo group (8%).23 In the RAINBOW trial, a study of ramucirumab in combination with paclitaxel also prolonged overall survival from 7.36 to 9.63 months (p = 0.0169).24,25 The FDA is expected to make its decision regarding the approval of ramucirumab in the second quarter of 2014.5 If approved, analysts project annual sales of ramucirumab to reach $3 billion.26 Eloctate™ (recombinant Factor VIII Fc) Eloctate is a recombinant Factor VIII Fc fusion protein product being developed by Biogen Idec and Swedish Orphan Biovitrum for the treatment of hemophilia A. Hemophilia A is a rare, inherited bleeding disorder that occurs in approximately 1 in 5,000 male births annually, affecting about 16,000 people in the United States.27 It is caused by having low or no Factor VIII activity, which is needed for normal blood clotting. Other FDA-approved recombinant Factor VIII products include Advate®, Xyntha®, Kogenate® FS, Helixate® FS, Recombinate®, and ReFacto®.1 Eloctate has orphan drug status and was developed using Biogen Idec’s monomeric Fc fusion technology, which results in a longer circulating half-life.28 Existing therapies require prophylactic infusions 2-3 times per week or every other day.1 Trials have studied Eloctate as individualized prophylactic therapy (given every 3-5 days with individual pharmacokinetics [PK]-guided dosing adjustments) and as weekly prophylactic therapy.28 The safety and efficacy of Eloctate was evaluated in the A-LONG clinical trial. Results showed that Eloctate’s median annualized bleeding rates, or projected number of yearly bleeding episodes, for prophylaxis and episodic treatments were 1.6-3.6 and 33.6, respectively.28 The FDA is expected to make its decision regarding the approval of Eloctate by June 12, 2014.5 If approved, analysts estimate Eloctate annual sales to reach $700 million by 2020.29 TBD (umeclidinium) Umeclidinium is a once-daily inhaled long-acting muscarinic acetylcholine receptor antagonist being developed by GlaxoSmithKline for the treatment of chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema. Umeclidinium, in combination with vilanterol, is a component of the FDA-approved product, Anoro™ Ellipta™.1 In a clinical trial, umeclidinium significantly improved mean OptumRx | optumrx.com 5 of 8 OptumRx Pipeline Forecast 1st Quarter 2014 change from baseline in trough forced expiratory volume in 1 second (FEV1) compared with placebo (p < 0.001).30 In another trial, umeclidinium showed comparable increases in FEV1 to Spiriva® (tiotropium).31 The FDA is expected to make its decision regarding the approval of umeclidinium by February 2014.5 Entyvio® (vedolizumab) Vedolizumab, a NME, is an anti-α4β7 integrin humanized monoclonal antibody. It is being developed by Takeda for reducing signs and symptoms, inducing and maintaining clinical response and remission, and mucosal healing, and achieving corticosteroid-free remission in adult patients with moderately to severely active ulcerative colitis (UC) who have had an inadequate response with, lost response to, or were intolerant to either conventional therapy or a TNFα antagonist. In a phase III induction trial, the proportion of patients with clinical response was significantly greater in the vedolizumab group (47.1%) relative to the placebo group (25.5%).33 In the maintenance trial, clinical remission was achieved by 41.8-44.8% of patients receiving vedolizumab compared to 15.9% of those receiving placebo (p < 0.0001).33 Though the mechanism of action for vedolizumab is similar to that of Tysabri® (natalizumab), a product that has been associated with progressive multifocal leukoencephalopathy (PML), no cases of PML have been observed thus far in the vedolizumab clinical program.32 Vedolizumab is administered intravenously, with a proposed maintenance dosing schedule of once every eight weeks. The FDA’s Gastrointestinal Drugs Advisory Committee and the Drug Safety and Risk Management Advisory Committee voted 21-0 in support of vedolizumab’s approval.33 The FDA is expected to make its decision regarding the approval of Entyvio by May 20, 2014.5 Expected Generic Launches Brand Name Generic Name Company Strength(s) and Formulation(s) Indication/Use Expected Launch Date* Avelox® moxifloxacin Bayer 400 mg tablets Sinusitis, chronic bronchitis, community acquired pneumonia, 2/2014 skin & skin structure infections, intra-abdominal infections Copaxone® glatiramer Teva 20 mg/mL injection Relapsing-remitting multiple sclerosis 5/2014 Humalog® lispro Eli Lilly 100 units/mL injection Type 2 diabetes mellitus 6/2014 * Estimated launch dates are subject to change based on various factors (e.g., FDA approvals, manufacturer decisions, litigation, and company agreements).
