Two New Drug Classes Tied to Better Survival in Type 2 Diabetes

Patients with type 2 diabetes who did not achieve adequate glycemic control with metformin had improved survival during follow-up if they received add-on therapy with a sodium-glucose cotransporter 2 (SGLT-2) inhibitor or a glucagon-like peptide 1 (GLP-1) agonist rather than a dipeptidyl peptidase-4 (DPP-4) inhibitor or control (placebo or no treatment), in a network meta-analysis that indirectly compared these three drug classes.

Rates of heart failure and myocardial infarction (MI) were also lower in patients who received SGLT-2 inhibitors rather than controls.

Merger to Establish Big Hospital Chain

Two large hospital systems in the Midwest and mid-Atlantic said they plan to merge, in another example of hospitals bulking up as the battle for patients becomes fierce.
 A combination of Bon Secours Health System Inc., a nonprofit based in Marriott sville, Md., and Mercy Health, a nonprofit in Cincinnati, would rank as one of the largest chains nationwide, with 43 hospitals and operations in seven states.
 The combination would add to a string of health-care deals that aim to create behemoths with more sway.

Profits Are Hidden in the Prescription Drug Supply Chain

Depending on how you look at them, pharmacy-benefit managers are either low margin middlemen that fight to reduce drug costs or highly profitable intermediaries that earn more when drug prices rise.
 Pharmacy-benefit managers are hired by businesses such as insurers that pay for drugs to negotiate lower prices with pharmaceutical companies. When Express Scripts Holding reports fourth-quarter earnings on Tuesday, analysts expect a margin of just 4.7%, according to FactSet. Rival companies owned by CVS Health and UnitedHealth Group report similarly low margins.
