Among the latest opinions issued by the European Medicines Agency’s Committee for Medicinal Products for Human Use, perhaps the most eye-catching are recommendations for two biosimilar versions of Johnson & Johnson’s monoclonal antibody blockbuster Remicade.
The CHMP has backed Remsima from South Korea’s Celltrion and Hospira’s Inflectra, both of which contain the same active substance as Remicade (infliximab). They have been recommended for authorisation in the same indications as the J&J drug, ie a range of autoimmune diseases such as rheumatoid arthritis, Crohn’s disease, ulcerative colitis, ankylosing spondylitis, psoriatic arthritis and and psoriasis.

Novartis Exelon® Patch now FDA approved to treat patients across all stages of Alzheimer’s disease
http://www.pharmalive.com/fda-oks-novartis-exelon-patch-for-alzheimers
Exelon Patch (rivastigmine transdermal system) contains rivastigmine, a reversible cholinesterase inhibitor known chemically as (S)- 3-[1-(dimethylamino) ethyl]phenyl ethylmethylcarbamate. It has an empirical formula of C14H22N2O2 as the base and a molecular weight of 250.34 (as the base). Rivastigmine is a viscous, clear, and colorless to yellow to very slightly brown liquid that is sparingly soluble in water and very soluble in ethanol, acetonitrile, n-octanol and ethyl acetate.
The distribution coefficient at 37°C in n-octanol/phosphate buffer solution pH 7 is 4.27.

Navidea Biopharmaceuticals, a Dublin, Ohio biopharmaceutical company focused on precision diagnostics, earlier this week announced the completion of a study of its novel radiopharmaceutical NAV4694 as a biomarker for Alzheimer’s disease (AD).
NAV4694 is designed to aid visual detection and quantification of cerebral beta amyloid in diagnosing Alzheimer’s disease (AD). One hallmark of AD is the accumulation of beta amyloid plaques between nerve cells in the brain.
The study was designed and conducted by Navidea’s partner, AstraZeneca, to assess the safety and of the biomarker during PET scanning in subjects with AD and in healthy volunteers. Efficacy measures included binding parameters and overall image quality. The 16-patient trial was completed at Karolinska Institutet sites in Stockholm, Sweden.

Rohypnol |  |
What is Rohypnol?“Roofies.” Sounds like a cartoon character or a piece of candy. However, nothing could be further from the truth about Roofies, also known as the drug Rohypnol.Rohypnol (Flunitrazepam) is a type of benzodiazepine, a class of drugs that depresses the central nervous system. You may have heard of Valium and Xanax. These are also benzodiazepines used as sedatives and antianxiety agents. Rohypnol was developed as a sleeping aid. It is also used in therapy settings to relax patients and to get them talking. Rohypnol is manufactured in Europe and Latin American and is sold in many countries around the world. However, it is illegal in the United States and Canada. The pills are round, white and smaller than aspirin. Because Rohypnol is inexpensive, it is becoming popular with high school and college students. In the US, Rohypnol is used mostly at parties, and usually taken with alcohol. It has a synergistic effect with other drugs such as alcohol. This means that one drug increases the effect of the other. |

Behavioral Effects of RohypnolRohypnol can produce amnesia (memory loss) and muscle relaxation and make people lower their inhibitions. An inhibition is when you feel like you can’t do something. When inhibitions are lowered, people feel as if an obstacle has been removed. Therefore, they can talk more freely and feel less shy. Continued, repeated use of Rohypnol may result in addiction and although Rohypnol is a sedative, it can cause aggressive behavior in some people. Withdrawal symptoms may occur and include headaches, sore muscles, hallucinations, convulsions, and possibly seizures 1-2 weeks after quitting the drug. Although overdoses are rarely fatal, emergency services are sometimes required because Rohypnol can cause a person to vomit, hallucinate, have trouble breathing and fall into a coma. When Rohypnol is combined with alcohol the outcome is usually worse. Street names for Rohypnol include rophies, ruffies, R2, roofenol, Roche, la rocha, rope, roopies, ropies, and rib. |
Because Rohypnol is colorless, odorless and flavorless, it can be slipped into drinks unnoticed. This is one reason this drug is so dangerous. People may consume it without knowing it. It dissolves quickly and takes effect in 20-30 minutes. Its effects can last 8-12 hours. Within the past few years, Rohypnol has become known as the “date rape” drug. People will come home from a party and have no idea what happened to them because they unknowingly ingested Rohypnol, passed out, and woke up several hours later with no memory of the evening. To address this new use, Congress passed the “Drug-Induced Rape Prevention and Punishment Act of 1996” to increase federal penalties for the use of any controlled substance to aid in a sexual assault.
Effects of Rohypnol on the BrainThe benzodiazepines influence behavior by interacting with receptors on neurons in the brain that use the neurotransmitter called GABA. When GABA binds to receptors, it usually inhibits a neuron and acts to reduce neuronal activity. When benzodiazepines attach to GABA receptors, they increase GABA binding to other receptors. In this way, benzodiazepines enhance the effects of GABA and reduce brain activity.The fact that there are receptors for benzodiazepines in the brain suggests that the brain makes its own type of benzodiazepine. The brain has been found to make its own morphine, the endorphins, but the brain’s own benzodiazepine has not yet been discovered.

Vical and Astellas Announce Initiation of Phase 3 Trial of ASP0113 Cytomegalovirus Vaccine

Comments Off on Vical and Astellas Announce Initiation of Phase 3 Trial of ASP0113 Cytomegalovirus Vaccine

Illustration of the CMV life cycle from viral entry to egress of new infectious virions.
Jun 25, 2013, Vical Incorporated and Astellas Pharma Inc. today announced the initiation of a multinational Phase 3 registration trial of ASP0113 (TransVax(TM)), in approximately 500 hematopoietic cell transplant (HCT) recipients. Vical and Astellas entered into exclusive worldwide license agreements in 2011 to develop and commercialize ASP0113, Vical’s investigational therapeutic vaccine designed to control cytomegalovirus (CMV) in transplant recipients. Astellas is conducting the trial, and Vical is providing development, regulatory and manufacturing support. The companies expect to begin a separate Phase 2 trial of ASP0113 in solid organ transplant (SOT) recipients later this year.
About ASP0113
ASP0113 is an investigational bivalent DNA vaccine containing plasmids (closed loops of DNA) encoding human CMV pp65 and gB antigens for induction of both cellular and humoral immune responses. ASP0113 is formulated with a proprietary poloxamer-based delivery system. ASP0113 has received orphan drug designation in the United States and Europe for HCT and SOT patients.
About CMV
CMV is a herpes virus that infects more than half of all adults in the United States by age 40, and is even more widespread in developing countries. A healthy immune system typically protects an infected person against CMV disease, but does not prevent or clear latent infection, and those whose immune systems are not fully functional are at high risk of CMV reactivation, potentially leading to severe illness or death. Those at greatest risk include transplant patients and infants born to mothers who first become infected during pregnancy. Vical is pursuing two distinct vaccine approaches for these separate market segments: ASP0113 for the transplant market and CyMVectin(TM) for the congenital disease market.
About Astellas
Astellas Pharma Inc., located in Tokyo, Japan, is a pharmaceutical company dedicated to improving the health of people around the world through the provision of innovative and reliable pharmaceutical products. Astellas has approximately 17,000 employees worldwide.
