FDA Approves Botox Cosmetic to Improve the Appearance of Crow’s Feet Lines


WEDNESDAY, September 11, 2013 — The U.S. Food and Drug Administration today approved a new use for Botox Cosmetic (onabotulinumtoxinA) for the temporary improvement in the appearance of moderate to severe lateral canthal lines, known as crow’s feet, in adults. Botox Cosmetic is the only FDA approved drug treatment option for lateral canthal lines.

The FDA approved Botox Cosmetic in 2002 for the temporary improvement of glabellar lines (wrinkles between the eyebrows, known as frown lines), in adults. Botox Cosmetic works by keeping muscles from tightening so wrinkles are less prominent

BOTOX Cosmetic (onabotulinum toxin A) For Injection, is a sterile, vacuum-dried purifiedbotulinum toxin type A, produced from fermentation of Hall strain Clostridium botulinumtype A grown in a medium containing casein hydrolysate, glucose, and yeast extract, intended for intramuscular use. It is purified from the culture solution by dialysis and a series of acid precipitations to a complex consisting of the neurotoxin, and several accessory proteins. The complex is dissolved in sterile sodium chloride solution containing Albumin Human and is sterile filtered (0.2 microns) prior to filling and vacuum-drying.

The primary release procedure for BOTOX Cosmetic uses a cell-based potency assay to determine the potency relative to a reference standard. The assay is specific to Allergan’s products BOTOX and BOTOX Cosmetic. One Unit of BOTOX Cosmetic corresponds to the calculated median intraperitoneal lethal dose (LD50) in mice. Due to specific details of this assay such as the vehicle, dilution scheme and laboratory protocols, Units of biological activity of BOTOX Cosmetic cannot be compared to nor converted into Units of any other botulinum toxin or any toxin assessed with any other specific assay method. The specific activity of BOTOX Cosmetic is approximately 20 Units/nanogram of neurotoxin protein complex.

Each vial of BOTOX Cosmetic contains either 50 Units of Clostridium botulinum type A neurotoxin complex, 0.25 mg of Albumin Human, and 0.45 mg of sodium chloride; or 100 Units of Clostridium botulinum type A neurotoxin complex, 0.5 mg of Albumin Human, and 0.9 mg of sodium chloride in a sterile, vacuum-dried form without a preservative.

Since the approval of BOTOX® Cosmetic by the U.S. Food and Drug Administration in 2002, Allergan has virtually changed the face of medical aesthetics. Men and women between the ages of 18 to 65 now have the ability to choose science-based, non-invasive medical aesthetic solutions, including BOTOX® Cosmetic and the JUVÉDERM® family of dermal fillers, to achieve their own results. Over the last seven years, there have been nearly 11.8 million BOTOX® Cosmetic treatments recorded in the United States.1 More importantly, its 97 percent satisfaction rating (survey of 117 patients)2,3 is just one indication of the trust consumers have placed in Allergan.

BOTOX® Cosmetic is a simple, non-surgical procedure for temporarily reducing the appearance of moderate to severe glabellar lines – the vertical frown lines between the eyebrows that look like an “11” – in adult women and men aged 18 to 65. BOTOX® Cosmetic reduces the activity of the muscles that cause the “11s” to form by blocking nerve impulses that trigger wrinkle-causing muscle contractions, creating an improved appearance between the brows. Results can last up to four months and may vary with each patient. Ask your doctor if BOTOX® Cosmetic is right for you.

idelalisib

Idelalisib (codenamed GS-1101 or CAL-101) is a drug under investigation for the treatment of chronic lymphocytic leukaemia. It is in Phase III clinical trials testing drug combinations with rituximab and/or bendamustine as of 2013. The substance acts as aphosphoinositide 3-kinase inhibitor; more specifically, it blocks P110δ, the delta isoform of the enzyme phosphoinositide 3-kinase.[1][2]

GDC-0032 is a potent, next-generation beta isoform-sparing PI3K inhibitor targeting PI3Kα/δ/γ with IC 50 of 0.29 nM/0.12 nM/0.97nM,> 10 fold over Selective PI3K [beta].

GS-1101 is a novel, orally available small molecule inhibitor of phosphatidylinositol 3-kinase delta (PI3Kdelta) develop by Gilead and is waiting for registration in U.S. for the treatment of patients with indolent non-Hodgkin’s lymphoma that is refractory (non-responsive) to rituximab and to alkylating-agent-containing chemotherapy and for the treatment of chronic lymphocytic leukemia. The compound is also in phase III clinical evaluation for the treatment of elderly patients with previously untreated small lymphocytic lymphoma (SLL) and acute myeloid leukemia. Clinical trials had been under way for the treatment of inflammation and allergic rhinitis; however, no recent development has been reported. Preclinical studies have shown that GS-1101 has desirable pharmaceutical properties. The compound was originally developed by Calistoga Pharmaceuticals, acquired by Gilead on April 1, 2011.

FOSTER CITY, Calif.–(BUSINESS WIRE)–Jan. 13, 2014– Gilead Sciences, Inc. (Nasdaq: GILD) announced today that the U.S. Food and Drug Administration (FDA) has accepted for review the company’s New Drug Application (NDA) for idelalisib, a targeted, oral inhibitor of PI3K delta, for the treatment of refractory indolent non-Hodgkin’s lymphoma (iNHL). FDA has granted a standard review for the iNHL NDA and has set a target review date under the Prescription Drug User Fee Act (PDUFA) of September 11, 2014.

The NDA for iNHL, submitted on September 11, 2013, was supported by a single arm Phase 2 study (Study 101-09) evaluating idelalisib in patients with iNHL that is refractory (non-responsive) to rituximab and to alkylating-agent-containing chemotherapy. Following Gilead’s NDA submission for iNHL, FDA granted idelalisib a Breakthrough Therapy designation for relapsed chronic lymphocytic leukemia (CLL). The FDA grants Breakthrough Therapy designation to drug candidates that may offer major advances in treatment over existing options. Gilead submitted an NDA for idelalisib for the treatment of CLL on December 6, 2013.

About Idelalisib

Idelalisib is an investigational, highly selective oral inhibitor of phosphoinositide 3-kinase (PI3K) delta. PI3K delta signaling is critical for the activation, proliferation, survival and trafficking of B lymphocytes and is hyperactive in many B-cell malignancies. Idelalisib is being developed both as a single agent and in combination with approved and investigational therapies.

Gilead’s clinical development program for idelalisib in iNHL includes Study 101-09 in highly refractory patients and two Phase 3 studies of idelalisib in previously treated patients. The development program in CLL includes three Phase 3 studies of idelalisib in previously treated patients. Combination therapy with idelalisib and GS-9973, Gilead’s novel spleen tyrosine kinase (Syk) inhibitor, also is being evaluated in a Phase 2 trial of patients with relapsed or refractory CLL, iNHL and other lymphoid malignancies.

Additional information about clinical studies of idelalisib and Gilead’s other investigational cancer agents can be found at http://www.clinicaltrials.gov. Idelalisib and GS-9973 are investigational products and their safety and efficacy have not been established.

About Indolent Non-Hodgkin’s Lymphoma

Indolent non-Hodgkin’s lymphoma refers to a group of largely incurable slow-growing lymphomas that run a relapsing course after therapy and can lead ultimately to life-threatening complications such as serious infections and marrow failure. Most iNHL patients are diagnosed at an advanced stage of disease, and median survival from time of initial diagnosis for patients with the most common form of iNHL, follicular lymphoma, is 8 to 10 years. The outlook for refractory iNHL patients is significantly poorer.

About Gilead Sciences

Gilead Sciences is a biopharmaceutical company that discovers, develops and commercializes innovative therapeutics in areas of unmet medical need. The company’s mission is to advance the care of patients suffering from life-threatening diseases worldwide. Headquartered in Foster City, California, Gilead has operations in North and South America, Europe and Asia Pacific.

The delta form of PI3K is expressed primarily in blood-cell lineages, including cells that cause or mediate hematologic malignancies, inflammation, autoimmune diseases and allergies. By specifically inhibiting only PI3K delta, a therapeutic effect is exerted without inhibiting PI3K signalling that is critical to the normal function of healthy cells. Extensive studies have shown that inhibition of other PI3K forms can cause significant toxicities, particularly with respect to glucose metabolism, which is essential for normal cell activity.

In 2011, orphan drug designation was assigned to GS-1101 in the U.S. for the treatment of CLL. In 2013, several orphan drug designations were assigned to the compound in the E.U. and U.S.: for the treatment of follicular lymphoma, for the treatment of mucosa-associated lymphoid tissue lymphoma (MALT), for the treatment of nodal marginal zone lymphoma, for the treatment of splenic marginal zone lymphoma, and for the treatment of chronic lymphocytic leukemia/small lymphocytic lymphoma. Orphan drug designation was also assigned in the U.S. for the treatment of lymphoplasmacytic lymphoma with or without Walenstom’s macroglobulinemia and, in the E.U., for the treatment of Waldenstrom’s macroglobulinemia (lymphoplasmacytic lymphoma).

Later in 2013, some of these orphan drug designations were withdrawn in the E.U.; for the treatment of chronic lymphocytic leukemia / small lymphocytic lymphoma, for the treatment of extranodal marginal-zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma), for the treatment of of nodal marginal-zone lymphoma and for the treatment of splenic marginal-zone lymphoma. In 2013, the FDA granted a breakthrough therapy designation for the treatment of chronic lymphocytic leukemia.

idelalisib

CAL-101 is an Oral Delta Isoform-Selective PI3 Kinase Inhibitor.

CAL-101 (GS 1101) is a potent PI3K p110δ inhibitor with an IC50 of 65 nM. PI3K-delta inhibitor CAL-101 inhibits the production of the second messenger phosphatidylinositol-3,4,5-trisphosphate (PIP3), preventing the activation of the PI3K signaling pathway and thus inhibiting tumor cell proliferation, motility, and survival. Unlike other isoforms of PI3K, PI3K-delta is expressed primarily in hematopoietic lineages. The targeted inhibition of PI3K-delta is designed to preserve PI3K signaling in normal, non-neoplastic cells. [3][4]

Stem cells


……………………………..

Stem cells are undifferentiated biological cells, that can differentiate into specialized cells and can divide (through mitosis) to produce more stem cells. They are found in multicellular organisms. In mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing adult tissues. In a developing embryo, stem cells can differentiate into all the specialized cells—ectoderm, endoderm and mesoderm (see induced pluripotent stem cells)—but also maintain the normal turnover of regenerative organs, such as blood, skin, or intestinal tissues.

There are three accessible sources of autologous adult stem cells in humans:

  1. Bone marrow, which requires extraction by harvesting, that is, drilling into bone (typically the femur or iliac crest),
  2. Adipose tissue (lipid cells), which requires extraction by liposuction, and
  3. Blood, which requires extraction through pheresis, wherein blood is drawn from the donor (similar to a blood donation), passed through a machine that extracts the stem cells and returns other portions of the blood to the donor.

Stem cells can also be taken from umbilical cord blood just after birth. Of all stem cell types, autologous harvesting involves the least risk. By definition, autologous cells are obtained from one’s own body, just as one may bank his or her own blood for elective surgical procedures.

Highly plastic adult stem cells are routinely used in medical therapies, for example in bone marrow transplantation. Stem cells can now be artificially grown and transformed (differentiated) into specialized cell types with characteristics consistent with cells of various tissues such as muscles or nerves through cell culture. Embryonic cell lines and autologous embryonic stem cells generated through therapeutic cloning have also been proposed as promising candidates for future therapies. Research into stem cells grew out of findings by Ernest A. McCulloch and James E. Till at the University of Toronto in the 1960s

Diseases and conditions where stem cell treatment is promising or emerging. Bone marrow transplantation is, as of 2009, the only established use of stem cells.

Medical researchers believe that stem cell therapy has the potential to dramatically change the treatment of human disease. A number of adult stem cell therapies already exist, particularly bone marrow transplants that are used to treat leukemia. In the future, medical researchers anticipate being able to use technologies derived from stem cell research to treat a wider variety of diseases including cancer, Parkinson’s disease, spinal cord injuries, Amyotrophic lateral sclerosis, multiple sclerosis, and muscle damage, amongst a number of other impairments and conditions. However, there still exists a great deal of social and scientific uncertainty surrounding stem cell research, which could possibly be overcome through public debate and future research, and further education of the public.

One concern of treatment is the risk that transplanted stem cells could form tumors and become cancerous if cell division continues uncontrollably.

Stem cells are widely studied, for their potential therapeutic use and for their inherent interest.

Supporters of embryonic stem cell research argue that such research should be pursued because the resultant treatments could have significant medical potential. It has been proposed that surplus embryos created for in vitro fertilization could be donated with consent and used for the research.

The recent development of iPS cells has been called a bypass of the legal controversy. Laws limiting the destruction of human embryos have been credited for being the reason for development of iPS cells, but it is still not completely clear whether hiPS cells are equivalent to hES cells. Recent work demonstrates hotspots of aberrant epigenomic reprogramming in hiPS cells (Lister, R., et al., 2011).

 

 

Pluripotent, embryonic stem cells originate as inner cell mass (ICM) cells within a blastocyst. These stem cells can become any tissue in the body, excluding a placenta. Only cells from an earlier stage of the embryo, known as the morula, are totipotent, able to become all tissues in the body and the extraembryonic placenta

MannKind Reports Positive Data from a Phase 3 Clinical Study of Afrezza in Patients with Type 1 Diabetes


The European Commission has approved the first copycat version of an antibody-based drug, clearing the way for increased competition for the makers of multi-billion dollar biotechnology drugs to treat complex diseases


Tuesday’s final green light for Inflectra – which was developed by South Korea’s Celltrion and will be marketed by U.S. company Hospira – had been expected following a European Medicines Agency recommendation in June.

Hospira said the drug for treating rheumatoid arthritis and some other conditions would be launched throughout Europe “at the earliest opportunity taking into account any relevant patent protection”.

Inflectra is a so-called biosimilar version of Johnson & Johnson and Merck & Co’s Remicade.

http://www.reuters.com/article/2013/09/10/celltrion-hospira-europe-idUSL5N0H620R20130910

remicade= infliximab

Infliximab (INN; trade name Remicade) is a monoclonal antibody against tumour necrosis factor alpha (TNF-α) used to treat autoimmune diseases. Remicade is marketed by Janssen Biotech, Inc. (formerly Centocor Biotech, Inc.) in the USA, Mitsubishi Tanabe Pharma in Japan, Xian Janssen in China, and Schering-Plough (now part of Merck & Co) elsewhere.[1] In 2013, two biosimilars were submitted for approval in Europe, by Hospiraand Celltrion Healthcare.[2]

Infliximab was approved by the U.S. Food and Drug Administration (FDA) for the treatment of psoriasisCrohn’s diseaseankylosing spondylitispsoriatic arthritisrheumatoid arthritis, and ulcerative colitis. Infliximab won its initial approval by the FDA for the treatment of Crohn’s disease in August 1998.[3]

Infliximab works by binding to TNF-α. TNF-α is a chemical messenger (cytokine) and a key part of the autoimmune reaction. In rheumatoid arthritis, infliximab seems to work by preventing TNF-α from binding to its receptor in the cell.

Infliximab is an artificial antibody. It was originally developed in mice as a mouse antibody. Because humans have immune reactions to mouse proteins, the mouse common domains were replaced with similar human antibody domains. Because the antibodies were produced from one cell grown into a clone of identical cells, it is called a monoclonal antibody. Furthermore, as a combination of mouse and human antibody amino acid sequences, it is called a chimeric monoclonal antibody.

Infliximab was developed by Junming Le and Jan Vilcek at New York University School of Medicine and developed by Centocor, (now Janssen Biotech, Inc.)[4]

In the United States, Infliximab can cost $19,000 to $22,000 a year per patient wholesale, according to Centocor.[5]

Other monoclonal antibodies targeting TNF-α are golimumab (Simponi), adalimumab(Humira), and certolizumab pegol (Cimzia). Etanercept also binds and inhibits the action of TNF-α, but is not a monoclonal antibody (it is instead a fusion of TNF-receptor and anantibody constant region).[6]

Infliximab is administered by intravenous infusion, typically at six- to eight-week intervals, at a clinic or hospital. It cannot be administered orally because the digestive system would destroy the drug.[7]
