TABUK LAUNCHES VIBATIV® FDA-APPROVED ANTIBIOTIC WITH LIFE-SAVING POTENTIAL IN SAUDI ARABIA

Vibativ ^®  treats patients with pneumonia and serious skin infections

NASHVILLE, Tenn. and RIYADH, Saudi Arabia, Sept. 29, 2025 /PRNewswire/ -- Specialty pharmaceutical companies Tabuk Pharmaceutical Manufacturing Company a fully owned subsidiary of Astra Industrial Group and a leading pharmaceutical company in the Middle East and Cumberland Pharmaceuticals Inc. (Nasdaq: CPIX), a specialty pharmaceutical company, today announced the launch of Cumberland's Vibativ^® (telavancin) injection in Saudi Arabia.

The announcement follows an agreement between the companies providing Tabuk with the exclusive rights to register and promote the product for patients in Saudi Arabia and other countries in the Middle East.

Vibativ is a patented, FDA-approved injectable anti-infective that can serve as a potentially life-saving treatment in patients with hospital-acquired and ventilator-associated pneumonia resulting from infections, including the flu and COVID-19. It is intravenously administered with once-daily dosing and does not require therapeutic drug monitoring, decreasing health care professionals' exposure to the patient. It is designed to treat serious infections due to Staphylococcus aureus (S. aureus) and other Gram-positive bacteria, including Methicillin-resistant Staphylococcus aureus (MRSA) and Methicillin-sensitive Staphylococcus aureus (MSSA). Vibativ addresses a range of Gram-positive bacterial pathogens, including those that are considered difficult-to-treat and multidrug-resistant.

"Given the global concern about multidrug-resistant organisms, Vibativ is an important addition to our anti-infective portfolio and supports our mission to deliver unique health solutions and save the lives of people throughout the Middle Eastern countries we operate in," said Ismail Shehadah, CEO of Tabuk. "We believe Vibativ will provide our physicians with a powerful new tool to battle multidrug-resistant infections and we are excited to launch the product in Saudi Arabia."

According to a recent report from the World Health Organization, antimicrobial resistance (AMR) is an urgent global health and socioeconomic crisis. Further, the global rise in antibiotic resistance poses a significant threat, diminishing the efficacy of many common antibiotics against widespread bacterial infections.

Unlike many recently introduced antibiotics that are quickly losing the battle to fight the bacteria they were designed to kill because those bacteria have become drug-resistant, Vibativ was specifically designed to kill drug-resistant bacteria. The molecule of an existing antibiotic to which bacteria had developed a resistance, vancomycin, was altered by adding a lipophilic (fat-loving) component and a hydrophilic (water-loving) component. The lipophilic addition increases Vibativ's ability to penetrate the cell wall and inhibits the formation of new cell walls (the development of new and/or additional cell walls is the most common way that bacteria become resistant to drugs). The hydrophilic addition increases Vibativ's penetration into tissue, and is able to attack infections that are not reachable by other antibiotics.

Studies show that Vibativ is just as potent today against difficult-to-treat and multidrug-resistant bacteria as it was when it was introduced over 10 years ago.

"We are very pleased to expand the reach of Vibativ – an important and potentially life-saving drug – through this partnership with Tabuk," said A.J. Kazimi, CEO of Cumberland Pharmaceuticals. "We are confident that Tabuk has the resources and experience to ensure Vibativ reaches as many patients in Saudi Arabia as possible."

About Vibativ^®

Vibativ^® (telavancin) injection was discovered in a research program dedicated to finding new antibiotics for serious infections due to Staphylococcus aureus (S. aureus) and other Gram-positive bacteria, including MRSA and MSSA. 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. and Saudi Arabia 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. and Saudi Arabia for the treatment of adult patients with complicated skin and 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.
