1. Certain insulins are similarly effective in reducing blood sugar but differ in their ability to lower a patient’s weight and HbA1c levels. The study, published in the Annals of Internal Medicine, compared three marketed GLP-1 receptor agonists—Eli Lilly’s Trulicity, AstraZeneca’s Bydureon and GlaxoSmithKline’s Tanzeum—and one in the development phase, Ipsen’s and Roche’s taspoglutide.

2. Public Citizen is taking aim at a provision the 21st Century Cures Act that would allow drugmakers to gain additional exclusivity for drugs approved with new indications for rare or orphan diseases. The provision could add $12 billion in additional costs over the next decade. (Public Citizen)

3. The FDA approved Kanuma (sebelipase alfa), the first therapy that treats patients with a rare disease called lysosomal acid lipase deficiency.

Men taking these drugs also have higher risks of cardiovascular disease, diabetes and high cholesterol, among other conditions. (WSJ)
