FDA Approves Pomalyst for Advanced Multiple Myeloma
We know that, Pomalidomide (INN, originally CC-4047 or 3-amino-thalidomide, marketed as Pomalyst by Celgene), is a derivative of thalidomide that is anti-angiogenic and also acts as an immunomodulator. Pomalidomide was approved on February 8, 2013 by the U.S. Food and Drug Administration (FDA) as a treatment for relapsed and refractory multiple myeloma....

FDA Approves Ravicti for the Chronic Management of Some Urea Cycle Disorders
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.

Top-line results from Vanda's tasimelteon Phase IIb/III study on major depressive disorder
We know that, Tasimelteon (BMS-214,778) is a drug which is under development for the treatment of insomnia and other sleep disorders. It is a selective agonist for the melatonin receptors MT1 and MT2 in the suprachiasmatic nucleus of the brain, similar to older drugs such as ramelteon. It has been through Phase III trials successfully and was shown to improve both onset and maintenance of sleep, with few side effects.
A year-long (2011-2012) study at Harvard is testing the use of tasimelteon in blind subjects with non-24-hour sleep-wake disorder.
Now Vanda Pharmaceuticals Inc. (NASDAQ: VNDA), announced top-line results of the Phase IIb/III clinical study (MAGELLAN) in Major Depressive Disorder (MDD), investigating the efficacy and safety of tasimelteon as a monotherapy in the treatment of patients with MDD. The clinical study did not meet the primary endpoint of change from baseline in the Hamilton Depression Scale (HAMD-17) after 8 weeks of treatment as compared to placebo. Both tasimelteon and placebo treated patients had an approximately 40% reduction of their MDD symptoms from baseline. Tasimelteon was shown to be safe and well-tolerated, consistent with observations in prior studies. Given these current proof of concept clinical study results, Vanda has decided to discontinue all activities in this indication.
Vanda has recently reported positive results in two phase III clinical studies of tasimelteon in Non-24-Hour Disorder (Non-24) and plans to submit a New Drug Application to the U.S. Food and Drug Administration in mid-2013......
"These results are disappointing, as there is still a significant unmet medical need for patients with Major Depression," said Mihael H. Polymeropoulos , M.D., President and CEO of Vanda. "Tasimelteon's application in the treatment of blind individuals with Non-24 remains our top priority as we pursue our planned NDA submission this year."

Hops, Key to Flavor in Beer, May Prove Useful in New Drugs - Drugs.com MedNews
We know that, Humulone (α-lupulic acid) is a bitter-tasting chemical compound found in the resin of mature hops (Humulus lupulus). Humulone is a prevalent member of the class of compounds known as alpha acids, which collectively give beer its characteristic bitter flavor.

In a new study, researchers determined the precise configuration of humulones, substances derived from hops that give beer its unique flavor.
"Now that we have the right results, what happens to the bitter hops in the beer-brewing process makes a lot more sense," study lead author Werner Kaminsky, a University of Washingto.
Previous research has suggested that moderate consumption of beer and therefore its bitter compounds might have positive effects on diseases such as diabetes and some types of cancer, as well as aiding weight loss and decreasing inflammation.
The new findings could help scientists determine which humulones might prove useful in efforts to develop new drugs, Kaminsky said.
The authors wrote in their report that while "excessive beer consumption cannot be recommended to propagate good health isolated humulones and their derivatives can be prescribed with documented health benefits."

Messenger RNA–Based Vaccines for Cancer | Articles | Drug Discovery and Development Magazine
Nucleic acids are being extensively investigated for use in gene therapy and in genetic vaccinations in which foreign nucleic acid is translated into proteins by the host cells. Vaccines based on DNA and messenger RNA (mRNA) are able to stimulate all effectors of the adaptive immune response: B lymphocytes, cytotoxic T cells, and T helper cells. This makes them a useful tool in the creation of prophylactic vaccines for infectious diseases and for cancer immunotherapy.
