A recent multinational, randomized, double-blind, placebo-controlled clinical trial demonstrated that administration of aliskiren provides additional renal protection to patients with hypertension, type 2 diabetes mellitus, and nephropathy who are already receiving optimal antihypertensive therapy and renal protective therapy with the angiotensin receptor blocker (ARB) losartan.
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.

Proquin XR), gemifloxacin (Factive), levofloxacin (Levaquin), moxifloxacin (Avelox), norfloxacin (Noroxin), and ofloxacin (Floxin).
In the Antiarrhythmic Trial with Dronedarone in Moderate to Severe CHF Evaluating Morbidity Decrease (ANDROMEDA) investigators observed that dronedarone, an anti-arrhythmic agent related to amiodarone, was associated with increased mortality in patients who were hospitalized for symptomatic heart failure (HF) (New York Heart Association [NYHA] class II, III, or IV) and left ventricular systolic dysfunction.

Drug Watch: Agents in late-stage development for the treatment of type 2 diabetes mellitus (August 2008)
The US orphan drug program has demonstrated that economic incentives and regulatory flexibility can spur development of treatments for small patient populations. Since enactment of the Orphan Drug Act (ODA) in 1983, FDA has approved >300 medicines for approximately 12 million patients around the world. However, there are approximately 6,000 to 8,000 rare diseases, so “we still have a very long way to go,” commented Janet Woodcock, director of the Center for Drug Evaluation and Research (CDER), at a May conference commemorating ODA’s 25th anniversary, which was sponsored by the Drug Information Association (DIA).
Hospital-acquired pneumonia (HAP) is a frequently occurring complication of endotracheal intubation and hospitalization that is associated with a significant increase in morbidity, mortality, and cost of care.
Tolvaptan is an oral selective vasopressin V2 receptor antagonist that works to produce aquaresis (water diuresis without electrolyte excretion) by blocking the effects of AVP. This effect makes tolvaptan a viable treatment option for patients with acute decompensated heart failure (ADHF) and hyponatremia.
Generic drugs approved by FDA (through July 2008) including fluoxetine capsules and calcipotriene topical solution.
Recent FDA action (through July 2008) related to tigecycline, bazedoxifene, balsalazide tablet, tacrolimus, fospropofol injection, bivalirudin, 13-valent pneumococcal conjugate vaccine, pirfenidone, LX1032, palifosfamide, SB1518, oral tetrathiomolybdate, and terguride.
Recent FDA approvals and indications (through July 2008) related to Abilify, Levaquin, Taclonex Scalp, Recothrom, and Seroquel.
New indication: Atomoxetine (Strattera), a selective norepinephrine reuptake inhibitor, was approved on May 7, 2008, for the maintenance treatment of ADHD in children and adolescents.
NME: Alvimopan (Entereg), a peripherally acting mu-opioid receptor antagonist, was approved on May 20, 2008, to accelerate the time to upper and lower GI recovery after partial large or small bowel resection surgery with primary anastomosis.
According to the results of an extended follow-up of the African American Study of Kidney Disease and Hypertension (AASK), long-term reduction of blood pressure to a lower goal than the standard demonstrates no significant effect on the progression of chronic kidney disease (CKD) in nondiabetic hypertensive patients, except in patients with baseline urinary protein/creatinine ratio >0.22, said Jackson Wright, MD, professor of medicine and director of the hypertension program at Case Western Reserve University, Cleveland. These results were presented at the 23rd Annual Scientific Meeting of the American Society of Hypertension, New Orleans, May 14–17, 2008.
Epoetin alfa in 1993 and darbepoetin alfa in 2002 were approved for the management of chemotherapy-induced anemia (CIA).
Drugs in development for the treatment of adult and juvenile rheumatoid arthritis
An investigational first-in-class dual angiotensin and endothelin receptor antagonist lowered systolic blood pressure (SBP) in patients with stage 1 and 2 hypertension in a phase 2a trial, reported Joel M. Neutel, MD, associate professor of medicine, University of California, Irvine, and medical director of clinical pharmacology, Orange County Research Center, Tustin, California. These results were presented at the 23rd Annual Scientific Meeting of the American Society of Hypertension, New Orleans, May 14–17, 2008.
The combination of amlodipine and olmesartan was demonstrated to be superior to monotherapy with either agent in difficult-to-treat hypertensive populations in a subgroup analysis of the registrational trial for this combination therapy. These results were presented at the 23rd Annual Scientific Meeting of the American Society of Hypertension, New Orleans, May 14–17, 2008.
Gut hormones play a key and often overlooked role in weight loss and weight regulation. Changes in weight are determined largely by the balance between energy intake and energy expenditure, but gut hormones can affect both sides of the energy equation.
The range of endothelial interventions for peripheral artery disease (PAD) is proliferating. Today's choices include traditional balloon angioplasty, stents, drug eluting stents and fabric-covered stents. Newer technologies allow clinicians to cut out occlusions, freeze them, scrape them, laser them and kill them.
