SAN FRANCISCO, Oct. 16 /PRNewswire/ -- Sugammadex -- the novel selective relaxant binding agent (SRBA) being developed by Organon -- demonstrated a faster recovery from profound neuromuscular blockade as compared to neostigmine in the Phase III pivotal Signal trial.(1) In a second trial, named Spectrum, faster recovery from profound neuromuscular blockade compared to spontaneous recovery was demonstrated.(2) The pivotal Signal trial results were presented today at the 2007 annual meeting of the American Society of Anesthesiologists (ASA) taking place in San Francisco from October 13-17. The Spectrum trial results were presented on October 14.
The Signal trial compared the efficacy and safety of sugammadex and neostigmine/glycopyrrolate for the reversal of profound rocuronium (Zemuron(R)/ Esmeron(R)/Eslax(R)) induced neuromuscular blockade. The Spectrum trial compared the efficacy and safety of sugammadex for reversal of profound rocuronium-induced neuromuscular blockade with that of spontaneous recovery from succinylcholine-induced blockade.
"The Signal trial results are clinically significant for anesthesiologists during neuromuscular blockade management, as with sugammadex they will be able to have control when using any depth of rocuronium-induced neuromuscular, and be able to reverse the blockade rapidly at any moment they want, which is not possible with current treatments," said Professor James E. Caldwell, University of California, San Francisco and one of the lead Signal trial investigators.
Reversal agents are used during general anesthesia to reverse the
effects of muscle relaxants, also called neuromuscular blocking agents
(NMBAs). Reversal of neuromuscular blockade enables spontaneous breathing
to recommence earlier which helps to get patients out of the operating room
quicker, freeing up capacity and personnel to help additional patients.
Adequate reversal reduces the risk of residual paralysis, which may cause a
number of serio
