FRIMLEY, England, September 13 /PRNewswire-FirstCall/ --
- Physicians Welcome New Option for Potentially Life Threatening Disease
- Daptomycin has a Rapidly Bactericidal Mode of Action
The launch of daptomycin for the treatment of both methicillin-sensitive and resistant Staphylococcus aureus (MSSA and MRSA) bloodstream infections (bacteraemia) and heart infections (right-sided infective endocarditis) has been announced today by Novartis Pharmaceuticals UK Ltd.(1) Daptomycin, one of only two new classes of antibiotic in over 20 years, has been shown to be as effective as existing agents in treating a range of serious Gram-positive infections, offering an important new option for healthcare professionals.
MRSA is a frequent cause of bacteraemia and is associated with serious complications, including endocarditis (in 30-40% of cases) and has a high mortality rate.(2) Over 7,000 people each year contract bacteraemia and the incidence is rising.(3) From 1993 to 2005 the number of deaths increased from 51 to 1,629.(4) There is evidence that some strains of MRSA are developing resistance to existing antibiotic options.(5) Daptomycin, which is rapidly bactericidal, has a specific mode of action, which reduces the likelihood of resistance developing. Daptomycin's once daily dosing and tolerability profile, with no need for therapeutic drug monitoring, has the potential to simplify the management of patients with complicated infections.
Dr Andrew Seaton, consultant in infectious diseases, Gartnavel general hospital, Glasgow welcomed the news, commenting; "Serious staphylococcal infections are extremely challenging for hospital specialists to treat, with about 40% in the UK now resistant to first line therapy. Daptomycin is a fast acting agent in these potentially difficult situations and is well tolerated by patients. This is an extremely important and welcomed development in the battle against serious MRSA infection."
Daptomycin is already approved for the treatment of complicated skin and soft tissue infections (cSSTI) caused by Staphylococcus aureus and other Gram positive bacteria, including MRSA.(1) Clinical trials in cSSTI showed daptomycin had a faster time to cure (63% of patients successfully treated with daptomycin achieved a clinical cure within four to seven days versus 33% with comparators such as vancomyin and anti-staphylococcal penicillins).(6)
Pivotal trial data published in The New England Journal of Medicine supports the use of daptomycin in the treatment of bacteraemia and endocarditis caused by MRSA. The head-to-head study demonstrated daptomycin single agent therapy was as effective as dual agent comparator treatments and also has a favourable safety and tolerability profile with more creatine phosphokinase (CK) elevations but significantly fewer renal side effects reported versus comparator treatments.(2) The favourable safety profile is an important factor in severely ill patients.
A recent survey suggests that there is delay in patients receiving appropriate treatment for MRSA in approximately 50% of cases.(7) Delaying effective treatment for 48 hours can increase mortality as well as result in longer hospital stays, thus increasing the burden on the healthcare system.(8-11) Since Daptomycin is equally effective in treating MSSA and MRSA, it represents an important new empirical treatment choice for patients with MRSA bacteraemia associated with right sided endocarditis or complicated soft skin tissue infections.(2)
About the product
Daptomycin was first approved in the UK in March 2006 and received a positive Scottish Medicines Consortium (SMC) recommendation for its use in treating complicated skin and soft tissue infections (cSSTIs) in March 2006.
Last month, The Committee for Medical Products for Human Use (CHMP) gave extended approval to daptomycin for the use in right-sided infective endocarditis (RIE) due to Staphylococcus aureus and Staphylococcus aureus bacteraemia (SAB) when associated with RIE or with cSSTI.
Daptomycin is an antibiotic with a distinct mode of action which has several notable features, including once-daily dosing and no requirement for serum drug monitoring, which may reduce the burden on healthcare professionals and hospitalisation costs.
