Feb 12 (Reuters) - An independent advisory panel to the U.S. Food and Drug Administration said a blood clot preventer developed by The Medicines Co should not be approved due to a lack of data to prove its efficacy.

The panel voted 7-2 against approving the drug, cangrelor, for use during angioplasty - a heart surgery for widening narrow or clogged arteries.

The panelists voted unanimously against allowing cangrelor's use in patients with stents, who are at an increased risk of events such as stent thrombosis - a blood clot that forms at the site of the stent.

FDA reviewers, made up of the agency's staff, expressed mixed views on cangrelor on Monday.
