FDA Complete Response Letter for Telavancin
Theravance Receives Complete Response Letter on the Telavancin New Drug Application for the Treatment of cSSSI
SOUTH SAN FRANCISCO, CA/February 26, 2009 - Theravance, Inc. announced today that it received a Complete Response letter from the U.S. Food and Drug Administration (FDA) outlining requirements for approval of telavancin for the treatment of complicated skin and skin structure infections (cSSSI). Telavancin is a novel, bactericidal, once-daily injectable investigational antibiotic studied in the treatment of cSSSI and hospital-acquired pneumonia (HAP) caused by Gram-positive bacteria, including resistant pathogens such as methicillin-resistant Staphylococcus aureus (MRSA).
The Complete Response letter requires a Risk Evaluation and Mitigation Strategy (REMS), data on patients with certain renal risk factors from the cSSSI and HAP studies, revisions to the draft label, and a customary safety update.
The REMS will consist of a Medication Guide, a communications plan and a timetable for submission of assessments to ensure the benefits of the drug outweigh the risk of potential teratogenicity. A boxed warning related to this risk will be included in the package insert noting that females of childbearing potential should have a negative pregnancy test prior to administration. A post-approval registry of pregnant women exposed to telavancin will also be required. The letter indicates that telavancin, if approved, will be classified as pregnancy category C. The HAP data can be provided by cross reference to the recently submitted New Drug Application (NDA). The required revisions to the draft labeling include monitoring of renal function and cautionary language regarding the use of telavancin in patients with certain renal risk factors.
The Complete Response does not include a requirement for any additional clinical trials for the continued review of the telavancin NDA for cSSSI.
"We are very pleased with the continued progress of our application and intend to address these requests promptly. We look forward to finalizing labeling discussions with the FDA in order to bring the benefit of telavancin to patients with these serious infections," said Rick E Winningham, Chief Executive Officer.
On November 19, 2008, telavancin received a favorable recommendation from the Anti-Infective Drugs Advisory Committee of the FDA for the treatment of cSSSI. The Committee voted 21 to 5 that the data presented demonstrate the safety and effectiveness of telavancin for treatment of cSSSI. The Committee also voted 18 to 5 (with 3 abstentions) that there are specific clinical situations in which the benefits of telavancin use in pregnant women with cSSSI would outweigh the risks, and 25 to 1 that a risk management strategy is needed to prevent unintended use of telavancin in pregnant women or women of child-bearing potential.
Telavancin is a bactericidal, once-daily injectable investigational antibiotic with a multifunctional mechanism of action. Telavancin was discovered by Theravance in a research program dedicated to finding new antibiotics for serious infections due to Staphylococcus aureus, including MRSA, and other Gram-positive bacteria. Telavancin inhibits the formation of the bacterial cell wall and disrupts bacterial cell membrane function. Theravance believes the additive mechanisms of action seen with telavancin speed bacterial killing while also reducing the risks of inducing resistance to telavancin or cross-resistance with other antibiotics. Telavancin has been studied in two Phase 3 programs, one in cSSSI and one in HAP, both of which demonstrated non-inferiority in the all-treated (AT) and clinically evaluable (CE) patient populations versus vancomycin. Theravance believes these clinical programs comprise the largest global studies ever conducted in patients with confirmed MRSA infections. The FDA is currently reviewing the telavancin marketing application for the treatment of cSSSI. In late January 2009, Theravance submitted to the FDA an NDA for the proposed indication to treat nosocomial pneumonia (also known as HAP) caused by Gram-positive bacteria such as MRSA.
