Commercialization in China through partnership with SciClone Pharmaceuticals

Expands access to potentially life-saving antibiotic in the world's second-largest pharmaceutical market

NASHVILLE, Tenn., May 28, 2026 /PRNewswire/ -- Cumberland Pharmaceuticals Inc. (Nasdaq: CPIX), an innovation focused biopharmaceutical company, today announced the launch of its Vibativ^® (telavancin) injection in China, following regulatory approval and a strategic partnership with SciClone Pharmaceuticals (Holdings) Limited.

The launch follows a previously announced agreement granting SciClone exclusive rights to register, promote and distribute telavancin, injection across China. The product's approval by China's National Medical Products Administration (NMPA) enables SciClone to commercialize the product in one of the world's largest and fastest-growing pharmaceutical markets.

Telavancin is a patented, FDA-approved injectable anti-infective that serves as a potentially life-saving treatment for patients with serious bacterial infections, including hospital-acquired and ventilator-associated pneumonia. The therapy is designed to treat 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.

"Launching telavancin in China marks a significant milestone in advancing our mission of providing unique products that improve the quality of patient care," said A.J. Kazimi, Cumberland Pharmaceuticals CEO. "Through our partnership with SciClone, we are expanding access to this important therapy and providing physicians in China with a valuable new option to treat serious, difficult-to-manage infections."

Antimicrobial resistance continues to be a critical global health challenge, reducing the effectiveness of many existing antibiotics and increasing the need for innovative treatments. Telavancin was specifically designed to address resistant pathogens, offering potent activity against difficult-to-treat infections.

Mr. Zhao Hong, President and Chief Executive Officer of SciClone Pharmaceuticals, stated, "The successful launch of telavancin for injection in China represents another important milestone for SciClone Pharmaceuticals in the anti-infective field. Currently, MRSA remains a serious challenge and poses a significant clinical threat, particularly in respiratory tract infections, especially those that are hospital-acquired. With its unique dual bactericidal mechanism, broad antibacterial spectrum, and once-daily dosing regimen, telavancin offers an important new anti-infective option for Chinese patients with severe infections, delivering both improved efficacy and clinical convenience. Looking ahead, SciClone Pharmaceuticals will continue to focus on severe infection and oncology, address unmet medical needs, and accelerate the launch of more innovative products in China to contribute to the 'Healthy China 2030' initiative."

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. It 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, telavancin 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 telavancin 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 telavancin 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.
