Emily BurkeDrug Delivery, Drug Development, Drug Discovery, Edited by Sarah Van Tiem, The WEEKLY

RED BLOOD CELLS: READY FOR DOUBLE-DUTY? Biotech Primer WEEKLY talks a lot about white blood cells, with good reason. These powerful immune cells defend us against pathogens and have recently been adapted to fight cancer as CAR-T cells. What about the body’s other major type of blood cell–red blood cells (RBCs)? Although they receive less media attention, scientists have long … Read More

Groundbreaking Migraine Drug Explained

Emily BurkeAuthor Emily Burke PhD, Drug Approvals, Drug Development, Drug Discovery, Drug Targets, Edited by Sarah Van Tiem, Migraine

FIRST IN CLASS MIGRAINE APPROVAL Last month the FDA approved Amgen’s (Thousand Oaks, CA) new migraine drug Aimovig, the first drug shown to prevent the onset of migraines. The drug significantly reduces the number of migraine days in difficult-to-treat (those that have failed 2 to 4 prior treatments) patient populations. In some patients dubbed “super responders”, migraines occurrence went from several times/month to no occurrence for 6 … Read More

Turning On Cellular Garbage Disposals

Emily BurkeDrug Discovery, Drug Targets, Proteasomes

Proteasomes to the Rescue Many drugs work by stopping overactive proteins that cause disease. The leukemia drug Gleevec, for example, is a small-molecule inhibitor (antagonist) of the protein Bcr-Abl, whose over-activity promotes excessive cell division. Humira treats a range of autoimmune diseases by stopping TNF-alpha, a protein that activates inflammation. Such antagonists can be powerful. However, it’s not always possible … Read More

Drug Discovery 101

Emily BurkeDrug Development, Drug Discovery, Drug Targets

On the Road to New Medicines For most of the 20th century, we discovered new drugs by trial and error. Scientists investigated countless unrelated compounds in animals to see which improved disease symptoms. For instance, in the 1950s and 60s, British scientists at Boots Laboratories tested hundreds of unrelated chemicals on guinea pigs searching for an alternative to aspirin for … Read More
