News Release

NASHVILLE, Tenn., May 11, 2020 /PRNewswire/ -- Cumberland Pharmaceuticals Inc. (NASDAQ: CPIX), a U.S. specialty pharmaceutical company announces two new publications detailing the sustained in vitro potency of Vibativ^® (telavancin) as part of a 7-year antimicrobial surveillance program. Both publications were part of continued surveillance of telavancin activity since 2011.  The first publication tested a global collection of 24,408 Gram-positive clinical isolates, and the second publication tested a U.S. collection of 15,882 S. aureus isolates. All isolates were collected from the SENTRY Antimicrobial Surveillance Program.

Vibativ is a patented, FDA approved anti-infective for the treatment of certain serious bacterial infections including hospital-acquired and ventilator-associated bacterial pneumonia. It is also approved for complicated skin and skin structure infections. It addresses a range of Gram-positive bacterial pathogens, including those that are considered difficult-to-treat and multidrug-resistant.

The global study published in Microbial Drug Resistance¹ reports that since 2011, there has been little or no change in telavancin activity against several important Gram-positive pathogen groups that include MRSA, CoNS, vancomycin-susceptible E. faecalis, S. pneumoniae, viridans group streptococci, and b-hemolytic streptococci. Telavancin maintained excellent antimicrobial activity against multidrug-resistant subsets of these pathogen groups and against ceftaroline-nonsusceptible (telavancin MIC₉₀ value, 0.06 μg/mL; 100% susceptible) and ceftaroline-resistant (telavancin MIC₉₀ value, 0.12 μg/mL; 100% susceptible) S. aureus isolates. Telavancin exhibited MIC₉₀ values of 0.06 mg/mL against the full global set of S. aureus isolates and the MRSA subset.

The U.S. study published in the Journal of Global Antimicrobial Resistance² focused on S. aureus isolates. Telavancin antimicrobial activity against MRSA and MDR MRSA isolates (MIC₅₀/₉₀ values, 0.03/ 0.06 mg/mL for both subsets) remained unchanged over the surveillance period 2014 - 2016, and all isolates were susceptible to telavancin. Previously published data on MRSA and multidrug-resistant (MDR) MRSA isolates (collected 2011–2013) were merged with the current isolate set to examine longer-term resistance trends. The telavancin results for the MRSA and MDR MRSA subsets were identical to corresponding MIC₅₀/₉₀ and susceptibility values reported for isolates collected in 2011–2013.

About Vibativ^®

Vibativ is a once-daily, injectable lipoglycopeptide antibiotic with in vitro potency, bactericidal activity within six hours, and penetration into target infection sites. The drug is approved in the U.S. for the treatment of adult patients with hospital-acquired and ventilator-associated bacterial pneumonia (HABP/VABP) caused by susceptible isolates of S. aureus when alternative treatments are not suitable. In addition, Vibativ is approved in the U.S. for the treatment of adult patients with complicated skin & skin structure infections (cSSSI) caused by susceptible isolates of Gram-positive bacteria, including S. aureus, both methicillin-susceptible (MSSA) and methicillin-resistant (MRSA) strains. The product labeling also describes the use of Vibativ in treating patients whose pneumonia or skin infection is complicated by concurrent bacteremia. The product's proven efficacy against difficult-to-treat Gram-positive infections has been demonstrated in several large, multinational registrational studies, which involved one of the largest cohorts of patients with S. aureus infections studied to date. Importantly, these studies demonstrated significantly higher cure rates for Vibativ as compared to vancomycin in HABP/VABP due to any single Gram-positive pathogen or S. aureus with vancomycin MIC ≥1 µg/mL. Additionally, there is extensive and well-documented evidence of the drug's in vitro potency and in vivo activity against a broad collection of Gram-positive bacterial pathogens, including those that are considered difficult-to-treat and multidrug-resistant.
