Takeda Receives FDA Approval For Three New Type 2 Diabetes Therapies
Furiex Pharmaceuticals Inc. Friday 25 jan 2013,confirmed that Takeda Pharmaceutical Company Limited has received approval from the U.S. Food and Drug Administration of three new type 2 diabetes therapies, NESINA (alogliptin) and the fixed-dose combination therapies, OSENI (alogliptin and pioglitazone) and KAZANO (alogliptin and metformin HCl), for the treatment of type 2 diabetes in adults as adjuncts to diet and exercise.
Under its agreement with Takeda, Furiex is entitled to receive a $25 million milestone payment as a result of this approval, as well as royalties on sales in the United States and potential sales-based milestones. Furiex has already been receiving royalty payments from Takeda for the sale of NESINA and LIOVEL in Japan.
“Receiving regulatory approvals for NESINA, OSENI and KAZANO in the U.S. marks an important milestone for Furiex,” said Fred Eshelman, chairman of Furiex.
“These approvals should enable Takeda to build on the success of NESINA in Japan and leverage its more than 20 years of clinical and patient experience in the type 2 diabetes therapeutic area.”
Type 2 diabetes is the most common form of diabetes and has reached epidemic proportions globally. The global health care expenditures to treat and prevent diabetes and its complications were estimated at $471 billion in 2012. In addition to diet and exercise, patients often need to take multiple medications to help manage blood glucose. Because of the chronic nature of this disease, combination therapy is often required to maintain diabetic control over many years of therapy.
NESINA is a DPP-4 inhibitor for the treatment of type 2 diabetes as an adjunct to diet and exercise. DPP-4 inhibitors address insulin deficiency by slowing the inactivation of incretin hormones GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic peptide).
OSENI is a fixed dose combination therapy that combines alogliptin and pioglitazone in a single tablet for the treatment of type 2 diabetes in adults as an adjunct to diet and exercise. Pioglitazone is a thiazolidinedione that directly targets insulin resistance, a condition in which the body does not efficiently use the insulin it produces to control blood glucose levels. It is currently approved for use in adults for the treatment of type 2 diabetes as an adjunct to diet and exercise.
KAZANO is a fixed dose combination therapy for the treatment of type 2 diabetes that combines alogliptin and metformin in a single tablet. Metformin is a widely-used diabetes medication that acts primarily by reducing the amount of glucose produced by the liver. These medications work in combination to help patients with type 2 diabetes manage their blood glucose levels.
Nesina® (alogliptin) is a member of a new class of drugs for the oral treatment of type 2 diabetes (T2D). Nesina is being developed and marketed by Takeda Pharmaceuticals. In April 2010, Takeda received regulatory approval from Japan’s Ministry of Health, Labour and Welfare for Nesina and it is now being sold in Japan.
Takeda has resubmitted a new drug application (NDA) with the U.S. Food and Drug Administration (FDA), and has submitted a Marketing Authorization Application (MAA) with the European Medicines Agency (EMA).
As a result of their collaboration, Furiex has rights to royalties and sales-based milestones from Takeda for the sale of Nesina in Japan. Furiex will be entitled to receive regulatory milestones, royalties and sales-based milestones upon marketing approval of Nesina in other countries.
Alogliptin is a DPP-4 inhibitor that slows the inactivation of incretin hormones GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic peptide), which play a major role in regulating blood glucose levels and have the potential to improve pancreatic beta-cell function.
Alogliptin has been studied in 12 Phase III trials including more than 8,000 patients. Pivotal trials demonstrated alogliptin was well-tolerated and it significantly improved glycemic control in T2D patients without raising the incidence of hypoglycemia. Additionally, alogliptin has been shown to enhance glycemic control when used in combination with other commonly prescribed diabetes drugs.
Alogliptin was tested in 329 drug-naive patients with inadequately controlled T2D in a double-blind, placebo-controlled, multicenter study. Patients were randomized to once-daily treatment with 12.5 mg or 25 mg alogliptin or placebo for 26 weeks. The primary efficacy end point was HbA(1c). Alogliptin was well-tolerated and significantly improved glycemic control in these patients with T2D without raising the incidence of hypoglycemia.

The U.S. Food and Drug Administration today approved Oxytrol for Women, the first over-the-counter treatment for overactive bladder in women
| 4-Diethylaminobut-2-ynyl 2-cyclohexyl-2-hydroxy-2-phenylethanoate |
January, 25, 2013 — The U.S. Food and Drug Administration today approved Oxytrol for Women, the first over-the-counter treatment for overactive bladder in women ages 18 years and older.
Oxytrol will remain available for men with overactive bladder by prescription only.
Overactive bladder is a condition in which the bladder squeezes too often or squeezes without warning. Symptoms include leaking urine (urinary incontinence), feeling the sudden and urgent need to urinate, and frequent urination. Overactive bladder affects an estimated 33 million Americans, the majority of whom are older women.
Oxytrol for Women contains oxybutynin, a medicine that helps relax the bladder muscle. Oxybutynin belongs to a class of drugs known as anticholinergics. It is the first drug in this class to be made available over-the-counter for treatment of overactive bladder.
Oxytrol for Women is a patch that is applied to the skin every four days. The patch delivers 3.9 milligrams of oxybutynin per day.
“Studies demonstrate that over-the-counter Oxytrol for Women is a safe and effective treatment for overactive bladder,” said Shaw Chen, M.D., Ph.D., deputy director of the Office of Drug Evaluation IV in the FDA’s Center for Drug Evaluation and Research. “Women should make sure to follow the Drug Facts label and consult their doctor if their condition does not improve.”
Oxytrol for Women’s safety and effectiveness for over-the-counter use were established in more than 5,000 subjects participating in nine studies. Overall, results from these studies showed that consumers can understand the information on the label, properly select whether the product is right for them, and use the drug appropriately.
Side effects reported during clinical studies were mild and included skin irritation where the patch was applied, dry mouth and constipation. A leaflet with tips to help manage overactive bladder will be provided with the product.
Oxytrol for Women is marketed by Merck, based in Whitehouse Station, N.J.
Oxybutynin (Ditropan, Lyrinel XL, Lenditro (South Africa)) is an anticholinergic medication used to relieve urinary and bladder difficulties, including frequent urination and inability to control urination (urge incontinence), by decreasing muscle spasms of the bladder.[2] It competitively antagonizes the M1, M2, and M3 subtypes of the muscarinic acetylcholine receptor. It also has direct spasmolytic effects on bladder smooth muscle as a calcium antagonist and local anesthetic, but at concentrations far above those used clinically. It is available orally in generic formulation or as the brand-names Ditropan, Lyrinel XL, or Ditrospam, as a transdermal patch under the brand name Oxytrol, and as a topical gel under the brand name Gelnique.
Oxybutynin is also a possible treatment of hyperhidrosis (hyper-active sweating).[3][4][5]

USFDA Approves first systemic antisense drug Kynamro (mipomersen sodium) Injection for treatment of Homozygous Familial Hyperholesterolemia
30 January 2013
Sanofi and its subsidiary Genzyme, and Isis Pharmaceuticals Inc today announced that the U.S. Food and Drug Administration (FDA) has approved its New Drug Application (NDA) for KYNAMRO(mipomersen sodium) injection. KYNAMRO, given as a 200 mg weekly subcutaneous injection, has been approved as an adjunct to lipid-lowering medications and diet to reduce low density lipoprotein-cholesterol (LDL-C), apolipoprotein B (Apo B), total cholesterol (TC), and non-high density lipoprotein-cholesterol (non HDL-C) in patients with homozygous familial hypercholesterolemia.
In the United States, HoFH, an orphan indication, occurs in approximately one in one million individuals. For those with HoFH, heart attacks and death often occur before age 30.
Mipomersen (previously ISIS 301012, trade name Kynamro) is a cholesterol-reducing drug candidate. It is an antisense therapeutic that targets the messenger RNA forapolipoprotein B.[1][2][3] It is administered as a weekly injection.Structure
The compound is a ‘second-generation’ antisense oligonucleotide; the nucleotides are linked with phosphorothioate linkages rather than the phosphodiester linkages of RNA andDNA, and the sugar parts are deoxyribose in the middle part of the molecule and 2′-O-methoxyethyl-modified ribose at the two ends. These modifications make the drug resistant to degradation by nucleases, allowing it to be administered weekly. The drug accumulates in the liver, which is convenient since apolipoprotein B predominantly acts there.

FDA APPROVES BIOTESTS BIVIGAM TO TREAT PRIMARY HUMORAL IMMUNODEFIECIENCY
FDA APPROVES BIOTESTS BIVIGAM TO TREAT PRIMARY HUMORAL IMMUNODEFIECIENCY
Jan 31, 2013,
Biotest Pharmaceuticals Corporation (BPC), a wholly owned U.S. subsidiary of Biotest AG, recently announced the U.S. Food and Drug Administration’s (FDA) approval of BIVIGAM™, its new intravenous immune globulin, for the treatment of patients with Primary Humoral Immunodeficiency (PI).
BIVIGAM is the first new intravenous immune globulin (IVIG) to be approved by the FDA with a validated assay for measuring potential thrombogenic activity. Thrombin generation tests are utilized to detect procoagulant activity. BPC plans to begin shipments of the product shortly.
To reduce the risk of thromboembolic events that PI patients have experienced in the past with alternative products, BPC initiated the development and validation of a TGA test in close cooperation with the FDA. Every lot of BPC’s BIVIGAM will be screened before release to assure the product fulfills the stringent release criteria pertaining to the threshold levels of Factor XIa. Increased Factor XIa has been identified as one of the risk factors associated with thromboembolic events following immune globulin intravenous therapy.
BIVIGAM is a sugar-free, glycine stabilized intravenous immune globulin that was approved by the FDA on December 19, 2012 and is available in 50 mL (5 gram) and 100 mL (10 gram) tamper-evident vials. The product uses a label with an integrated hanger and the packaging material is latex free. It is manufactured in a state-of-the-art US facility and will be available exclusively for patients and healthcare professionals in the USA. For Full Prescribing Information and more information about the product, the indication and additional services, please visit www.BIVIGAM.com.
BIVIGAM is a purified, sterile, ready-to-use preparation of concentrated humanimmunoglobulin G (IgG) antibodies. The distribution of IgG subclasses is similar to that of normal plasma.19,20 The active ingredient is human immunoglobulin purified from source human plasma and processed using a modified classical Cohn Method 6 / Oncley Method 9 fractionation procedure. BIVIGAM contains 100 ± 10 mg/mL protein, of which not less than 96% is human immunoglobulin obtained from source human plasma. It is formulated in water for injection containing 0.100-0.140 M sodium chloride, 0.20-0.29 M glycine, 0.15–0.25% polysorbate 80, and pH 4.0–4.6. BIVIGAM contains ≤ 200 μg/mL of IgA.
Each plasma donation used for the manufacture of BIVIGAM is collected from FDA licensed facilities and undergoes rigorous testing. Plasma donations must test negative for hepatitis B virus (HBV) surface antigen (HBsAg), antibodies to human immunodeficiency virus (HIV) strains 1 and 2 (anti-HIV-½), and antibodies to the hepatitis C virus (anti-HCV) as determined by enzyme immuno assay (EIA). In addition, each plasma unit must test negative and/or non-reactive for HIV RNA, HCV RNA, HBV DNA, Hepatitis A Virus (HAV) RNA, and Parvovirus B19 (B19 virus) DNA as determined by Nucleic Acid Amplification Testing (NAT) of plasma minipools. NAT for B19 virus DNA is also performed on a sample of the manufacturing pool and the limit for B19 virus DNA in a manufacturing pool is set not to exceed 104 IU/mL.
The manufacturing process of BIVIGAM employs three steps to remove/inactivateadventitious viruses to minimize the risk of virus transmission. The steps are “Precipitation and removal of fraction III” during cold ethanol fractionation, classical “Solvent/detergent treatment” and “35 nm virus filtration”. In compliance with current guidelines, the steps have been separately validated in a series of in vitro experiments for their capacity to inactivate or remove both enveloped and non-enveloped viruses.
Precipitation and removal of fraction III removes both enveloped and non-enveloped viruses, solvent/detergent treatment represents a virus inactivation step for enveloped viruses, and 35 nm virus filtration removes both enveloped and non-enveloped viruses by size exclusion. In addition to the steps above, low pH during several steps of the production process contributes to virus inactivation. The results of virus validation studies for BIVIGAM are shown in Table 3, expressed as log10 reduction factors.
FDA Approves Ravicti (glycerol phenylbutyrate), feb 2013, for the Chronic Management of Some Urea Cycle Disorder

FDA Approves Ravicti (glycerol phenylbutyrate)for the Chronic Management of Some Urea Cycle Disorders
Ravicti is marketed by Hyperion Therapeutics, based in South San Francisco, Calif.
February 1, 2013 — The U.S. Food and Drug Administration today approved Ravicti (glycerol phenylbutyrate) for the chronic management of some urea cycle disorders (UCDs) in patients ages 2 years and older.
UCDs are genetic disorders that involve deficiencies of specific enzymes involved in the urea cycle, a series of biochemical steps normally required to remove ammonia from the blood. When protein is absorbed and broken down by the body, it produces nitrogen as a waste product. The urea cycle removes nitrogen from the blood and converts it to urea, which is removed from the body through urine. In people with UCDs, nitrogen accumulates and remains in the body as ammonia, which can travel to the brain and cause brain damage, coma or death.
Ravicti, a liquid taken three times a day with meals, helps dispose of ammonia in the body. It is intended for patients whose UCD cannot be managed by a protein-restricted diet or amino acid supplements alone. Ravicti must be used with a protein-restricted diet and, in some cases, dietary supplements.
“Ravicti provides another treatment for chronic management of urea cycle disorders, a group of life-threatening conditions,” said Donna Griebel, M.D., director of the Division of Gastrointestinal and Inborn Errors Products in the FDA’s Center for Drug Evaluation and Research. “The approval of this new therapeutic option demonstrates FDA’s commitment to providing treatments for patients suffering from rare diseases.”
Ravicti was reviewed under the agency’s fast track program, designed to facilitate the development and expedite the review of drugs to treat serious diseases, fill unmet medical needs, and get important new drugs to patients earlier. Ravicti also was granted orphan product designation because it is intended to treat a rare disease.
Glycerol phenylbutyrate (HPN-100) is a pro-drug of phenylbutryrate and a pre-pro-drug of phenylacetic acid (PAA), the active moiety of Buphenyl, the only therapy currently FDA-approved as adjunctive therapy for the chronic management of patients with the most prevalent urea cycle disorders — carbamylphosphate synthetase, ornithine transcarbamylase, and argininosuccinic acid synthetase. HPN-100, which is dosed orally in liquid form, provides an alternative pathway to the urea cycle for the disposal of waste nitrogen through the renal excretion of phenylacetylglutamine, which is formed from PAA and glutamine.
RAVICTI (glycerol phenylbutyrate) is a clear, colorless to pale yellow oral liquid. It is insoluble in water and most organic solvents, and it is soluble in dimethylsulfoxide (DMSO) and > 65% acetonitrile.
Glycerol phenylbutyrate is a nitrogen-binding agent. It is a triglyceride containing 3 molecules of PBA linked to a glycerol backbone, the chemical name of which is benzenebutanoic acid, 1′, 1′ ‘ –(1,2,3-propanetriyl) ester with a molecular weight of 530.67. It has a molecular formula of C33H38O6.
