AstraZeneca, Bristol-Myers Squibb's dapagliflozin meets goals of late-stage diabetes study

Publicado el 20 septiembre 2010 por Fat
AstraZeneca and Bristol-Myers Squibb announced Monday that their experimental type 2 diabetes drug dapagliflozin met the main goals of a Phase III trial. Dapagliflozin, which the companies may file for regulatory approval later this year or in early 2011, is a first-in-class sodium-glucose cotransporter-2 (SGLT2) inhibitor being developed as a once-daily oral therapy for the treatment of adult patients with type 2 diabetes, according to the drugmakers.
The trial enrolled 597 patients with type 2 diabetes that was inadequately controlled with at least half the recommended dose of glimepiride. The patients were randomised to receive one of three doses of dapagliflozin or placebo, all in combination with glimepiride, which is marketed as Amaryl by sanofi-aventis. Results at 24 weeks showed that patients taking the SGLT2 inhibitor and glimepiride had significant reductions from baseline in HbA1c of -0.58 percent, -0.63 percent and -0.82 percent for the three doses, respectively, compared to -0.13 percent in the glimepiride arm.
The companies also reported that those patients who received dapagliflozin and glimepiride achieved greater weight loss, -1.18 kg, -1.56 kg, -2.26 kg for the three doses of dapagliflozin, respectively, compared to -0.72 kg for glimepiride plus placebo at week 24. Additionally, more patients taking the experimental drug achieved an HbA1c level of less than 7 percent compared to placebo.
In regards to adverse events, the drugmakers said that these were mostly similar in the different treatment arms, but the data showed that reports suggestive of genital tract infections were more frequently reported in those treated with dapagliflozin.
Last year, AstraZeneca and Bristol-Myers Squibb reported positive results from another Phase III trial of dapagliflozin, when used in combination with metformin. Johnson & Johnson is also developing a SGLT2 inhibitor, canagliflozin, which is currently in Phase III trials.
