FDA OKs 1-Month Dual Antiplatelet Therapy for Abbott's Xience Stents

The US Food and Drug Administration (FDA) has approved 1-month — as short as 28 days — dual antiplatelet therapy (DAPT) labeling for Xience stents in patients at high risk for bleeding, Abbott announced today.

Patients who receive stents are typically on DAPT regimens such as aspirin and P2Y12 inhibitors for 6 to 12 months to prevent blood clots, but high-bleeding risk patients can experience bleeding during prolonged DAPT.

"The new FDA approval for DAPT for the XIENCE family of stents provides interventional cardiologists confidence they are delivering the best care to patients with high bleeding risk. A short DAPT duration minimizes risks for high bleeding risk patients and allows them to return to daily life sooner and with more assurance," Roxana Mehran, MD, Icahn School of Medicine at Mount Sinai in New York City and the global principal investigator for Abbott's Short DAPT program (XIENCE 28 and XIENCE 90), said in a news release.

The new labeling comes on the heels of European CE Mark approval for the Xience stents with DAPT as short as 28 days, "giving Xience stents the shortest DAPT indication in the world," the company noted.

Results of the XIENCE 28 trial were used to support the new CE Mark DAPT indication. The trial showed no increase in death or myocardial infarction (MI) between 1 and 6 months and a significantly lower risk for severe bleeding with the Xience stent and 1-month DAPT compared with 6-month DAPT in more than 1600 high-bleeding risk patients.

The XIENCE 90 trial involving more than 2000 high-bleeding risk patients reported no difference in death or MI between 3 and 12 months with Xience and 3-month DAPT vs 12-month DAPT.

Abbott scored a second win, today announcing FDA and CE Mark approval of its next-generation Xience Skypoint stent in high-bleeding risk patients with 1-month DAPT.

"XIENCE Skypoint is easier to place and allows physicians to treat larger blood vessels through improved stent expansion that can open clogged vessels more effectively," the company said.
