(sNDA)…..FDA okays Shire ADHD drug Vyvanse (lisdexamfetamine dimesylate) for binge eating


 

 

Lisdexamfetamine-Structural Formula V.1.svg

Yet more good news for Shire has come with the US Food and Drug Administration approving its attention-deficit hyperactivity disorder blockbuster Vyvanse for binge-eating disorder, the first medicine approved by the agency to treat this condition.

The agency has expanded approval on Vyvanse (lisdexamfetamine dimesylate) for adults with BED based on two Phase III studies which showed that it was statistically superior to placebo in terms of number of binge days per week. BED affects around 2.8 million US adults and is more prevalent than anorexia nervosa and bulimia nervosa combined.

Read more at: http://www.pharmatimes.com/Article/15-01-30/FDA_okays_Shire_ADHD_drug_Vyvanse_for_binge_eating.aspx

 

Originally discovered and developed by New River Pharmaceuticals, the company entered into a collaborative agreement with Shire Pharmaceuticals in 2005 for global commercialization of the drug candidate. After Shire’s acquisition of New River Pharmaceuticals in April 2007, lisdexamfetamine entered the product portfolio of Shire.

 

 

 

In 2009, the compound was licensed to GlaxoSmithKline by Shire in the U.S. for comarketing for the treatment of attention deficit/hyperactivity disorder (ADHD). In 2010, this license agreement was terminated. The product was licensed to Shionogi by Shire in Japan for co-development, co-commercialization, and co-promotion for the treatment of attention deficit/hyperactivity disorder (ADHD).

Lisdexamfetamine (NRP-104), a conditionally bioreversible derivative of amphetamine, was launched in the U.S. in 2007 for the treatment of attention deficit hyperactivity disorder (ADHD) in children aged 6-12 years old. In 2008, the product was approved for use in adults, and in 2009 it was approved in Canada, followed by commercialization in 2010. In 2010, FDA approval was obtained for use in treatment of ADHD in adolescents aged 13 to 17 years and launch took place the same year. Approval for the treatment of adolescents was assigned in Canada in 2011.

 

In 2012, Shire filed a regulatory application in Europe via the decentralized procedure with the U.K. acting as the reference member state, for the treatment of ADHD in children and adolescent patients aged 6 to 17 years. This indication was approved in 2013. Also, in 2012 FDA approval was granted for the maintenance treatment for adults with ADHD. U.K., DK and SE are awaiting approval for the same indication in a decentralized procedure initiated in 2014 with the U.K. acting as the reference member state. In 2014, the company filed with priority review a supplemental New Drug Application (sNDA) in the U.S. for the treatment binge eating in adults.

Binge eating,,,,,, express their stress as temper tantrums or by indulging in compulsive eating spree


In terms of clinical development, phase III clinical trials are ongoing at Shionogi in Japan for the treatment of ADHD.. The National Institute on Drug Abuse (NIDA) is evaluating the compound in early clinical studies for the treatment of methamphetamine dependence. Phase III trials were underway as an adjunctive treatment of major depressive disorder; however, they were discontinued due to lack of efficacy. A phase II clinical trial for the treatment of excessive daytime sleepiness (EDS) has been completed. Shire had been evaluating the compound in clinical studies for the treatment of chronic fatigue syndrome.

In 2013, Shire cancelled its phase III program evaluating the product for the negative symptoms of schizophrenia based on a review and prioritization of the company’s development portfolio.

FDA approves Navidea’s Lymphoseek for expanded use in head and neck cancer patients

The US Food and Drug Administration (FDA) has approved Navidea Biopharmaceuticals’ Supplemental New Drug Application (sNDA) for the expanded use of Lymphoseek (technetium Tc 99m tilmanocept) Injection indicated for guiding sentinel lymph node (SLN) biopsy in head and neck cancer patients with squamous cell carcinoma of the oral cavity.

http://drugdelivery.pharmaceutical-business-review.com/news/fda-approves-navideas-lymphoseek-for-expanded-use-in-head-and-neck-cancer-patients-160614-4294154

NCI: 99mTc-DTPA-mannosyl-dextran A radiolabeled macromolecule consisting of the chelating agent diethylenetriamine pentaacetic acid (DTPA) and mannose each attached to a dextran backbone and labeled with metastable technetiumTc-99 (Tc-99m), with mannose binding and radioisotopic activities. Upon injection, the mannose moiety of 99mTc-DTPA-mannosyl-dextran binds to mannose-binding protein (MBP). As MBPs reside on the surface of dendritic cells and macrophages, this gamma-emitting macromolecule tends to accumulate in lymphatic tissue where it may be imaged using gamma scintigraphy. This agent exhibits rapid clearance from the injection site, rapid uptake and high retention within the first draining lymph node, and low uptake by the remaining lymph nodes. MBP is a C-type lectin that binds mannose or fucose carbohydrate residues, such as those found on the surfaces of many pathiogens, and once bound activates the complement system.

 

The active ingredient in technetium Tc 99m tilmanocept is technetium Tc 99m tilmanocept. The active ingredient is formed when Technetium Tc 99m pertechnetate, sodium injection is added to the tilmanocept powder vial.

Technetium Tc 99m binds to the diethylenetriaminepentaacetic acid (DTPA) moieties of the tilmanocept molecule.

Chemically, technetium Tc 99m tilmanocept consists of technetium Tc 99m, dextran 3-[(2- aminoethyl)thio]propyl 17-carboxy-10,13,16- tris(carboxymethyl)-8-oxo-4-thia-7,10,13,16- tetraazaheptadec-1-yl 3-[[2-[[1-imino-2-(D- mannopyranosylthio) ethyl]amino]ethyl]thio]propyl ether complexes. Technetium Tc 99m tilmanocept has the following structural formula:

Empirical formula: [C6H10O5]n.(C19H28N4O9S99mTc)b.(C13H24N2O5S2)c.(C5H11NS)a

Calculated average molecular weight: 15,281 to 23,454 g/mol

It contains 3-8 conjugated DTPA (diethylenetriamine pentaacetic acid) molecules (b); 12-20 conjugated mannose molecules (c) with 0-17 amine side chains (a) remaining free.

The tilmanocept powder vial contains a sterile, non-pyrogenic, white to off-white powder that consists of a mixture of 250 mcg tilmanocept, 20 mg trehalose dihydrate, 0.5 mg glycine, 0.5 mg sodium ascorbate, and 0.075 mg stannous chloride dihydrate. The contents of the vial are lyophilized and are under nitrogen.

Technetium Tc 99m tilmanocept injection is supplied as a Kit. The Kit includes tilmanocept powder vials which contain the necessary non-radioactive ingredients needed to produce technetium Tc 99m tilmanocept. The Kit also contains DILUENT for technetium Tc 99m tilmanocept. The diluent contains a preservative and is specifically formulated for technetium Tc 99m tilmanocept. No other diluent should be used.

The DILUENT for technetium Tc 99m tilmanocept contains 4.5 mL sterile buffered saline consisting of 0.04% (w/v) potassium phosphate, 0.11% (w/v) sodium phosphate (heptahydrate), 0.5% (w/v) sodium chloride, and 0.4% (w/v) phenol. The pH is 6.8 – 7.2.http://www.druginformation.com/RxDrugs/T/Technetium%20Tc%2099m%20Tilmanocept%20Injection.html

 

Lymphoseek(TM) is a lymphatic tissue-targeting agent which was first launched in 2013 in the U.S. by Navidea Biopharmaceuticals (formerly known as Neoprobe) for lymphatic mapping with a hand-held gamma counter to assist in the localization of lymph nodes draining a primary tumor site in patients with breast cancer or melanoma. In 2014, a supplemental NDA was approved in the U.S. for its use as a sentinel lymph node tracing agent in patients with head and neck squamous cell carcinoma of the oral cavity. Although several tracing agents exist that are used in “off-label” capacities, Lymphoseek is the first tracing agent specifically labeled for lymph node detection.

In 2012, an MAA was filed in the E.U. for the detection of lymphatic tissue in patients with solid tumors, and in 2013, a supplemental MAA was filed in the E.U. for sentinel lymph node detection in patients with head and neck cancer. The products is also awaiting registration to support broader and more flexible use in imaging and lymphatic mapping procedures, including lymphoscintigraphy and other optimization capabilities.

Navidea holds an exclusive worldwide license of Lymphoseek(TM) through the University of California at San Diego (UCSD), and, in 2007, Lymphoseek(TM) was licensed to Cardinal Health by Navidea for marketing and distribution in the U.S.

Lymphoseek(TM), also known as [99mTc]DTPA-mannosyl-dextran, is a receptor-binding radiopharmaceutical designed specifically for the mapping of sentinel lymph nodes in connection with gamma detection devices in a surgical procedure known as intraoperative lymphatic mapping (ILM). It is made up of multiple DTPA and mannose units, each attached by a 5-carbon thioether spacer to a dextran backbone. The compound features subnanomolar affinity for the mannose binding protein receptor, and consequently shows low distal node accumulation. Additionally, its small molecular diameter of 7 nanometers allows for enhanced diffusion into lymphatic channels and capillaries.

Chemical structure of [99mTc]tilmanocept. [99mTc]Tilmanocept is composed of a dextran backbone (black) to which are attached multiple units of mannose (green) and DTPA (blue). The mannose units provide a molecular mechanism by which [99mTc]tilmanocept avidly binds to a receptor specific to reticuloendothelial cells (CD206), and the DTPA units provide a highly stable means to radiolabel tilmanocept with 99mtechnetium (red). The molecular weight of [99mTc]tilmanocept is approximately 19,000 g/mol; the molecular diameter is 7.1 nm

[(99m)Tc]Tilmanocept is a CD206 receptor-targeted radiopharmaceutical designed for sentinel lymph node (SLN) identification. Two nearly identical nonrandomized phase III trials compared [(99m)Tc]tilmanocept to vital blue dye.

Technetium (99mTc) tilmanocept, trade name Lymphoseek, is a radiopharmaceutical diagnostic imaging agent approved by the U.S. Food and Drug Administration (FDA) for the imaging of lymph nodes.[1][2] It is used to locate those lymph nodes which may be draining from tumors, and assist doctors in locating those lymph nodes for removal during surgery.[3]

Radiopharmaceuticals for use in therapy employ radionuclides which are generally longer in half-life and weaker in penetration capability, but emit stronger radiation, sufficient to kill cells, in relation to that for use in diagnosis. Alpha ray-emitting radionuclides are excluded from radiopharmaceuticals for the reason that they are highly radioactive and difficult to purchase and to attach to other compounds. All of the radionuclides currently used in pharmaceuticals are species that emit beta rays.

As mentioned above, radiopharmaceuticals, whether for use in therapy or diagnosis, are prepared by labeling pharmaceuticals with specific radionuclides. Technetium-99m (99mTc) is known as the radioisotope most widely used to label radiopharmaceuticals. Technetium-99m has a half life of as short as 6 hours and emits gamma rays at 140 KeV, and thus it is not so toxic to the body. In addition, gamma radiation from the radioisotope is highly penetrative enough to obtain images. Thanks to these advantages, technetium-99m finds a broad spectrum of therapeutic and diagnostic applications in the nuclear medicine field (Sivia, S. J., John, D. L., Potential technetium small molecule radiopharmaceuticals. Chem. Rev. 99, 2205-2218, 1999; Shuang, L., Edwards, D. S., 99mTc-Labeled small peptides as diagnostic radiopharmaceuticals. Chem. Rev. 99, 2235-2268, 1999).

Methods of labeling 99mTc-2,6-diisopropylacetanilidoiminodiacetic acid are well known in the art (Callery, P. S., Faith, W. C., et al., 1976. Tissue distribution of technetium-99m and carbon-labeled N-(2,6)-dimetylphenylcarbamoylmethyl iminodiacetic acid. J. Med. Chem. 19, 962-964; Motter, M. and Kloss, G., 1981. Properties of various IDA derivatives. J. Label. Compounds Padiopharm. 18, 56-58; Cao, Y. and Suresh, M. R. 1998. A Simple And Efficient Method For Radiolabeling Of Preformed Liposomes. J Pharm Pharmaceut Sci. 1 (1), 31-37).

Basically, the conventional methods are based on the following reaction formula. In practice, a solution of SnCl2.2H2O, serving as a reducing agent of technetium-99m, in 0.1 N HCl and 0.1 ml (10 mCi) of sodium pertechnetium were added to lyophilized 2,6-diisopropylacetanilidoiminodiacetic acid in a vial, followed by stirring at room temperature for 30 min to prepare 99mTc-2,6-diisopropylacetanilidoiminodiacetic acid. The preparation of 99mTc-2,6-diisopropylacetanilidoiminodiacetic acid may be realized according to the following reaction formula.

 

 

Such conventional processes of preparing radiopharmaceuticals labeled with technetium-99m can be divided into reactions between the radioisotope and a physiologically active material to be labeled and the separation of labeled compounds from unlabeled compounds.

June 24, 2013 , Astellas Pharma US, Inc. (“Astellas”), a U.S. subsidiary of Tokyo-based Astellas Pharma Inc. (Tokyo: 4503), announced that the U.S. Food and Drug Administration (FDA) has approved its Supplemental New Drug Application (sNDA) for the use of MYCAMINE® (micafungin sodium) for injection by intravenous infusion for the treatment of pediatric patients four months and older with candidemia, acute disseminated candidiasis, Candida peritonitis and abscesses, esophageal candidiasis, and prophylaxis of Candida infections in patients undergoing hematopoietic stem cell transplants (HSCT).

Micafungin (trade name Mycamine) is an echinocandin antifungal drug developed by Astellas Pharma. It inhibits the production of beta-1,3-glucan, an essential component of fungal cell walls. Micafungin is administered intravenously. It received final approval from the U.S. Food and Drug Administration on March 16, 2005, and gained approval in the European Union on April 25, 2008.

Micafungin is indicated for the treatment of candidemia, acute disseminated candidiasis, Candida peritonitis, abscesses and esophageal candidiasis. Since January 23, 2008, micafungin has been approved for the prophylaxis of Candida infections in patients undergoing hematopoietic stem cell transplantation (HSCT).

Micafungin works by way of concentration-dependent inhibition of 1,3-beta-D-glucan synthase resulting in reduced formation of 1,3-beta-D-glucan, which is an essential polysaccharide comprising one-third of the majority of Candida spp. cell walls. This decreased glucan production leads to osmotic instability and thus cellular lysis

  • Micafungin sodium, FK-463, Mycamine, Funguard,208538-73-2

  • The synthesis of FK-463 can be performed as follows: The enzymatic deacylation of FR-901379 with Streptomyces anulatas No. 4811, S. anulatas No. 8703, Streptomyces strain No. 6907 or A. utahensis IFO13244 gives the deacylated lipopeptide FR-179642 (1), which is then reacylated with 1-[4-[5-(4-pentyloxyphenyl)isoxazol-3-yl]benzoyl]benzotriazole 3-oxide (VI) by means of dimethylaminopyridine (DMAP) in DMF. The acylating compound (VI) can be obtained as follows: The cyclization of 4-pentyloxyphenylacetylene (I) with 4-(hydroxyiminomethyl)benzoic acid methyl ester (II) by means of triethylamine in hot THF gives 4-[5-(4-pentyloxyphenyl)isoxazol-3-yl]benzoic acid methyl ester (III), which is hydrolyzed with NaOH in hot THF/water yielding the corresponding free acid (IV). Finally, this compound is condensed with 1-hydroxybenzotriazole (V) by means of 1-ethyl-3-[3-(dimethylamino)propyl]carbodiimide (EDMCA) in dichloromethane.

FDA Accepts sNDA for Higher Concentration Dose of Copaxone


Teva Announces FDA Acceptance of sNDA for a Higher Concentration Dose of COPAXONE® Given Three Times a Week

http://www.pharmalive.com/fda-accepts-snda-for-higher-concentration-dose-of-copaxone

Glatiramer acetate (also known as Copolymer 1Cop-1, or Copaxone – as marketed by Teva Pharmaceuticals) is an immunomodulator drug currently used to treat multiple sclerosis. It is a random polymer of four amino acids found in myelin basic protein, namelyglutamic acid, lysine, alanine, and tyrosine, and may work as a decoy for the immune system. Glatiramer acetate is approved by the Food and Drug Administration (FDA) for reducing the frequency of relapses, but not for reducing the progression of disability. Observational studies, but not randomized controlled trials, suggest that it may reduce progression of disability.

Although the clinical definition of multiple sclerosis requires two or more episodes of symptoms and signs, glatiramer acetate is approved for treatment after single episodes. It is also used to treat relapsing-remitting multiple sclerosis. It is administered bysubcutaneous injection.

Bristol-Myers Squibb Receives US FDA sNDA Approval for Use of SUSTIVA® (efavirenz) in HIV-1 Infected Pediatric Patients

 

Approval offers a once-daily option as part of a regimen for HIV-1 infected infants as young as three months and weighing at least 3.5 kg

 

“Capsule sprinkle” administration allows dosing in patients who cannot swallow capsules or tablets

 

“Bristol-Myers Squibb recognizes the importance of offering alternative methods of administration of HIV medicines, including for pediatric patients who cannot swallow tablets or capsules, and their caregivers who help manage their treatment,”

 

Bristol-Myers Squibb Company first week may 2013, announced that the U.S. Food and Drug Administration (FDA) has approved a supplemental new drug application (sNDA) for SUSTIVA® (efavirenz), including dosing recommendations for HIV-1 infected pediatric patients three months to three years old and weighing at least 3.5 kg. This approval offers a once-daily option as part of a regimen for this population and includes a “capsule sprinkle” administration method for patients who cannot swallow capsules or tablets. Detailed information about the “capsule sprinkle” method is provided in the ‘Instructions for Use’ at the end of the Patient Information section of the Package Insert.

 

SUSTIVA is a non-nucleoside reverse transcriptase inhibitor (NNRTI) that was originally approved in the U.S. in 1998 to treat HIV-1 infected children three years of age or older and weighing at least 10 kg. SUSTIVA is not to be taken by patients who are allergic to efavirenz, or to any of its ingredients.

 

“Bristol-Myers Squibb recognizes the importance of offering alternative methods of administration of HIV medicines, including for pediatric patients who cannot swallow tablets or capsules, and their caregivers who help manage their treatment,” said Brian Daniels, M.D., Senior Vice President, Global Development and Medical Affairs. “This approval is one example of our enduring commitment to the HIV patient community.”

 

This sNDA was based on results from three open-label studies that evaluated the pharmacokinetics, safety, and antiretroviral activity of SUSTIVA in combination with other antiretroviral agents in 182 antiretroviral-naïve and –experienced HIV-1 infected pediatric patients (three months to 21 years of age) for a median of 123 weeks. Virologic and immunologic response was observed across all ages at the end of the studies, as measured by HIV RNA and CD4 cell count.

  • FDA Approves Supplemental New Drug Application for AMITIZA® (lubiprostone), the First Oral Treatment for Opioid-induced Constipation in Adults with Chronic Non-Cancer Pain

Apr. 23, 2013– Sucampo Pharmaceuticals, Inc. and Takeda Pharmaceuticals U.S.A., Inc. announced today that the United States (U.S.) Food and Drug Administration (FDA) has approved Sucampo’s supplemental new drug application (sNDA) for Amitiza (lubiprostone) (24 mcg twice daily) as the first and only oral medication for the treatment of opioid-induced constipation (OIC) in adult patients with chronic, non-cancer pain. The effectiveness of Amitiza in the treatment of opioid-induced constipation in patients taking diphenylheptane opioids (e.g., methadone) has not been established.

AMITIZA®

This is the third indication for Amitiza, which is also approved in the U.S. for the treatment of chronic idiopathic constipation (CIC) in adults (24 mcg twice daily) and irritable bowel syndrome with constipation (IBS-C) in adult women (8 mcg twice daily). There are more than 200 million prescriptions for opioid use in the U.S. annually, and a substantial number of these prescriptions are for non-cancer chronic pain. Scientific literature indicates that approximately 40-80% of patients taking opioids chronically for non-cancer pain report constipation.

Opioid-based medicines are widely used in the management of chronic pain, with OIC being a common adverse effect of chronic opioid use. Some patients may discontinue opioid therapy and thereby endure pain rather than suffer from the constipation the opioids cause.

Amitiza is a specific activator of ClC-2 chloride channels in the intestinal epithelium. Amitiza, via activation of apical ClC-2 channels in the intestinal epithelium, bypasses the antisecretory action of opiates.

This approval is based on results from Phase 3, well-controlled studies of 12 weeks’ duration in patients taking opioids (among them morphine, oxycodone, and fentanyl) chronically for non-cancer pain, as well as a long-term, open-label safety study, which provides additional support for use in this population. Two of the Phase 3 studies met their overall efficacy endpoint, while a third Phase 3 study did not.

OIC is a common adverse effect of chronic opioid use. Binding of opioids to peripheral opioid receptors in the gastrointestinal tract results in absorption of electrolytes, such as chloride, and subsequent reduction in small intestinal fluid. In addition, activation of enteric opioid receptors results in abnormal GI motility. Together, these processes result in OIC, which is characterized by infrequent and incomplete evacuation of stool, hard stool consistency, and straining associated with bowel movements.

Takeda Pharmaceutical Co   Takeda

Amitiza (lubiprostone) capsules are indicated for the treatment of chronic idiopathic constipation (CIC) in adults and opioid-induced constipation (OIC) in adults with chronic, non-cancer pain (24 mcg twice daily). The effectiveness in patients with OIC taking diphenylheptane opioids (e.g., methadone) has not been established. Amitiza is also indicated for irritable bowel syndrome with constipation (IBS-C) in women > 18 years old (8 mcg twice daily).

Lubiprostone (rINN, marketed under the trade name Amitiza) is a medicationused in the management of chronic idiopathic constipation and irritable bowel syndrome. It was approved by the U.S. Food and Drug Administration (FDA) for this purpose on 31 January 2006.

Lubiprostone is used for the treatment of chronic constipation of unknown cause and irritable bowel syndrome associated with constipation.

As of 20 July 2006, Lubiprostone had not been studied in children. There is current research underway to determine the efficacy in postoperative bowel dysfunction, and opioid-induced bowel dysfunction

Daiichi Sankyo Receives Approval in Japan for Manufacture and Marketing of PRALIA ®


Daiichi Sankyo Receives Approval 25 mar 2013, in Japan for Manufacture and Marketing of PRALIA ® for the osteoporosis treatment PRALIA ®subcutaneous injection 60mg syringe (INN: Denosumab; genetic recombination) for the treatment of osteoporosis.

Denosumab[1] is a fully human monoclonal antibody for the treatment of osteoporosis, treatment-induced bone loss, bone metastases, rheumatoid arthritis, multiple myeloma, and giant cell tumor of bone.[2][3] It was developed by the biotechnology company Amgen.[4]
Denosumab is designed to inhibit RANKL (RANK ligand), a protein that acts as the primary signal for bone removal. In many bone loss conditions, RANKL overwhelms the body’s natural defenses against bone destruction.
In June 2010, denosumab was approved by the U.S. Food and Drug Administration (FDA) for use in postmenopausal women with risk of osteoporosis under the trade name Prolia,[5] and in November 2010, as Xgeva, for the prevention of skeleton-related events in patients with bone metastases from solid tumors.[6] Denosumab is the first RANKL inhibitor to be approved by the FDA.[7] In the summer of 2011 clinical trials were investigating denosumab in giant cell tumors, multiple myeloma with bone metastases, and hypercalcemia of malignancy, and further investigating its dosing and safety.[8]
