FDA Advisory Committee Recommends Sugammadex for Approval
The FDA is not bound by the committee's recommendations; however, they usually are considered carefully before a final decision on approval is made.
Upon FDA approval, sugammadex will be the first and only selective relaxant binding agent (SRBA) and will give anesthesiologists the ability to rapidly and predictably reverse any depth of muscle relaxation induced by rocuronium and vecuronium within minutes. Sugammadex allows for flexible dosing of muscle relaxation agents enabling anesthesiologists to maintain optimal block through the end of the procedure.
"We are very pleased with the outcome of today's advisory committee meeting and appreciate the panel's careful consideration of the data on sugammadex," said Robert J. Spiegel, M.D., Chief Medical Officer and Senior Vice President, Schering-Plough Research Institute. "Sugammadex has the potential to transform the practice of anesthesia through improved management of muscle relaxation in the millions of surgeries where these agents are used. We will continue to work with FDA to bring sugammadex to the U.S. market as soon as possible so that anesthesiologists and their patients can benefit from this innovative product."
Earlier this year, Schering-Plough announced that the FDA assigned priority review status to the company's New Drug Application (NDA) for sugammadex. In the U.S., priority review is granted to drugs that FDA believes will provide meaningful benefit over existing treatment options.
Sugammadex is specifically designed to reverse the effects of certain widely used muscle relaxants, marketed in the United States as ZEMURON® (rocuronium bromide) and vecuronium bromide. Muscle relaxants are used as part of general anesthesia during surgical procedures. Sugammadex works in an entirely novel way to encapsulate the muscle relaxant molecule and restore muscle function so that patients can breathe on their own again. Reversal with sugammadex is generally rapid and can even be used in emergency situations when immediate reversal of rocuronium is needed.
Sugammadex is a novel selective relaxant binding agent (SRBA) under development by Organon, a part of Schering-Plough Corporation. Sugammadex was designed to reverse the effects of rocuronium bromide (ZEMURON/ESMERON®/ESLAX®) or vecuronium bromide, muscle relaxants commonly used during surgeries that require profound muscle relaxation. Anesthesiologists use muscle relaxation to improve surgical conditions, to facilitate intubation and mechanical ventilation, and to reduce the chance of complications.
In clinical trials to date, sugammadex has demonstrated the ability to rapidly reverse shallow and profound depths of rocuronium-induced muscle relaxation, thereby enabling control of the onset and offset of skeletal muscle relaxation through the use of both drugs(1). Sugammadex also has demonstrated the ability to reverse the effects of muscle relaxation induced by vecuronium bromide. The most common adverse reactions (incidence >5%) seen with sugammadex in clinical trials were anesthetic complications generally due to restoration of muscle function (8.0%) and dysgeusia (12.6%).
ZEMURON (rocuronium bromide) is a non-depolarizing muscle relaxant. It was introduced in the United States in 1994 and is one of the most widely used muscle relaxants in the United States, Canada and many European countries (where it is marketed under the brand name ESMERON). It was approved for use in Japan on July 31, 2007, under the brand name ESLAX. To date, it has been used in over 140 million patients worldwide, including an estimated 20 million patients in 2006.
Important Safety Information About ZEMURON
There have been rare reports of severe anaphylactic reactions to ZEMURON (rocuronium bromide) Injection, including some that have been life threatening. Clinicians should be prepared for the possibility of these reactions and take the necessary precautions, including the immediate availability of emergency treatment. ZEMURON Injection should be administered by experienced clinicians who are familiar with the drug's actions and the possible complications of its use.
