Combination Type 2 Diabetes Pill Approved in Europe


July 27, 2012 — The European Commission has approved the combination pill containing the dipeptidyl peptidase-4 inhibitor linagliptin and metformin hydrochloride for the treatment of adults with type 2 diabetes, alongside diet and exercise. The approval follows a favorable recommendation by the European Medicines Agency in May.
The linagliptin/metformin combination sold in Europe as Jentadueto (Boehringer Ingelheim Pharmaceuticals, Inc, and Eli Lilly & Co) provides a single-tablet option that is taken twice daily.
It is intended for patients with type 2 diabetes that is inadequately controlled on their maximal tolerated dose of metformin alone, metformin plus a sulfonylurea, or those already being treated with the combination of linagliptin and metformin. It can be used alone or in combination with a sulfonylurea.
As previously reported by Medscape Medical News, the linagliptin/metformin combination was approved by the US Food and Drug Administration earlier this year.
In a 24-week, randomized, double-blind, placebo-controlled study involving 791 adults with type 2 diabetes inadequately managed with diet and exercise, 2.5 mg linagliptin/1000 mg metformin led to mean reductions in hemoglobin A1c levels of 1.7 percentage points. Statistically significant reductions in fasting plasma glucose (FPG) of −60 mg/dL were also seen.
In clinical studies, linagliptin/metformin did not cause any significant change in body weight.
Adverse reactions were uncommon in clinical studies. Gastrointestinal disorders occurred most often during the initiation period and tended to resolve spontaneously. A comparable rate of diarrhea was reported with linagliptin/metformin treatment vs metformin plus placebo.
Hypoglycemia was more commonly reported in patients treated with the combination of linagliptin/metformin and a sulfonylurea compared with those treated with the combination of placebo, metformin, and a sulfonylurea.
The linagliptin/metformin combination pill is not indicated for patients with type 1 diabetes or those who have diabetic ketoacidosis. It has not been studied in combination with insulin.
Linagliptin/metformin combination tablets will be made available in the following twice-daily doses in Europe: 2.5 mg linagliptin/850 mg metformin tablets and 2.5 mg linagliptin/1000 mg metformin tablets.

Contact Precautions May Have Unintended Consequences

Contact precautions, including gloves, gowns, and isolated rooms, have helped stem the transmission of hospital pathogens but have also had some negative consequences, according to findings from a new study. Healthcare worker (HCWs) visited patients on contact precautions less frequently than other patients and spent less time with those patients when they did visit, report Daniel J. Morgan, MD, from the University of Maryland School of Medicine and the Veterans Affairs (VA) Maryland Health Care System, Baltimore, and colleagues. Moreover, patients on contact precautions also received fewer outside visitors. "Less contact with HCWs suggests that other unintended consequences of contact precautions still exist," Dr. Morgan and coauthors write. "The resulting decrease in HCW contact may lead to increased adverse events and a lower quality of patient care due to less consistent patient monitoring and poorer adherence to standard adverse event prevention methods (such...

FDA Decision Delayed for Truvada in HIV PrEP

June 11, 2012 — The US Food and Drug Administration (FDA) has delayed its decision on allowing the use of tenofovir disoproxil fumarate/emtricitabine ( Truvada , Gilead) as preexposure prophylaxis (PrEP) so that the proposed risk evaluation and mitigation strategy (REMS) can be reviewed. In early May, the FDA's Antiviral Drugs Advisory Committee  strongly backed  approval of the first-ever drug for the prevention of sexually acquired HIV-1 infection. However, concerns by the panel at the time included that people may neglect condom use if they feel they are protected by PrEP. Panelists were also concerned that uninfected people taking PrEP who become infected with HIV may not switch to a 3-drug regimen as recommended. According to the company, the FDA has postponed the target date to September 14 so it can review Gilead's REMS plan to help ensure that patients will not misuse the drug. The committee's recommendation for supplemental approval of tenofovir/emtricit...

Antidepressants Linked to Higher Diabetes Risk in Kids

Pediatric patients who use antidepressants may have an elevated risk for type 2 diabetes, the authors of a new study report. In a retrospective cohort study of more than 119,000 youths 5 to 20 years of age, the risk for incident type 2 diabetes was nearly twice as high among current users of certain types of antidepressants as among former users, Mehmet Burcu, PhD, and colleagues report in an article  published online October 16 in  JAMA Pediatrics . The risk intensified with increasing duration of use, greater cumulative doses, and higher daily doses of these antidepressants. The findings point to a growing need for closer monitoring of these products, including greater balancing of risks and benefits, in the pediatric population, the authors caution. They undertook the study because, despite growing evidence of an association between antidepressant use and an increased risk for type 2 diabetes in adults, similar research in pediatric patients was scarce. "To our know...
