Among the new data presented at the 68th Scientific Sessions of the ADA were the results of phase 3 trials of the investigational agents liraglutide, ABT-335, saxagliptin, and alogliptin.

Tocilizumab, an investigational agent for the treatment of moderate-to-severe rheumatoid arthritis, is a humanized anti-IL-6 receptor monoclonal antibody. Because tocilizumab contains a mouse monoclonal antibody grafted onto human immunoglobulin, the grafted antibody is less antigenic and has a longer half-life than the mouse antibody. When administered, tocilizumab inhibits IL-6 activity by competing for both the membrane-bound and soluble types of IL-6 receptors, thus eliminating IL-6 transduction into the cell.

Erythropoietin, a humoral factor produced predominantly in the kidney, stimulates red blood cell production in the bone marrow. Erythropoiesis-stimulating agents (ESAs) have been used for years in the treatment of anemia, with extensive experience and benefits in anemia of chronic kidney disease. Recent data have suggested adverse consequences with use of ESAs, perhaps relating to inappropriate use, and prompting release of guidelines to ensure safe use and maximize benefit. When prescribing ESAs, indications, requirements to monitor laboratory parameters (hemoglobin levels and ferrokinetics), and clinical status need to be stringently followed.

In an effort to simplify therapy for patients with asthma or COPD, products have been designed that combine medications from 2 separate therapeutic classes.

Iloperidone, a new-generation atypical antipsychotic, is currently under investigation for the treatment of schizophrenia. In 4 separate phase 3 trials, iloperidone has demonstrated efficacy in treating schizophrenia, with total Positive and Negative Symptom Scale (PANSS) scores decreasing by a range of 8 to 14 points depending on the iloperidone dose.

Istradefylline, a highly selective adenosine A2A receptor antagonist, is a new agent being investigated for the adjunctive treatment of the motor signs and symptoms of idiopathic Parkinson disease.

According to results from the Ongoing Telmisartan Alone and in Combination with Ramipril Global Endpoint Trial (ONTARGET), the angiotensin receptor blocker (ARB) telmisartan is as effective as the angiotensin-converting enzyme (ACE) inhibitor ramipril in preventing adverse cardiovascular events in high-risk patients with cardiovascular disease but without heart failure.

Experts urged a “return to statins” after hearing the final results of the Ezetimibe and Simvastatin in Hypercholesterolemia Enhances Atherosclerosis Regression (ENHANCE) trial, which demonstrated no slowing of carotid atherosclerosis progression with the addition of ezetimibe to simvastatin therapy.

Approximately 1.7 million healthcare-associated infections (HAIs) occur in US hospitals each year. These HAIs, which include pneumonia, bloodstream infections (BSIs), and urinary tract infections (UTIs), account for approximately 99,000 deaths and $5 billion in additional healthcare costs.
