CHICAGO--( BUSINESS WIRE )--Meitheal Pharmaceuticals, Inc. (“Meitheal”), a fully integrated biopharmaceutical company based in Chicago focused on the development and commercialization of generic, fertility, biologic, and branded injectable products, announced it has secured exclusive commercial rights in the U.S. to XENLETA ® (lefamulin acetate) through an exclusive license and supply agreement with its parent company, Hong Kong King-Friend Industrial Co., Ltd. (HKF). XENLETA ® belongs to a new class of novel antibiotics and is approved in intravenous and oral formulations in the U.S. and multiple other countries for the treatment of community-acquired bacterial pneumonia (CABP) in adults. HKF has acquired global rights to XENLETA ® (with the exception of Greater China) from Nabriva Therapeutics. Through the acquisition, HKF has obtained substantially all global assets related to XENLETA ® , including results of development and regulatory activities. “The licensing of XENLETA ® bolsters our portfolio of novel antibiotics and reflects our focus on addressing the growing issue of antimicrobial resistance,” said Tom Shea, Chief Executive Officer of Meitheal. “As the first approved medicine of an entirely new class of antibiotics, XENLETA ® is an innovative therapeutic option that will be available to the patients affected by CABP and has been shown to be active against various bacterial strains. We look forward to leveraging our end-to-end expertise in biopharmaceutical development and commercialization to bring this important therapeutic to patients in need.” XENLETA ® is a first-in-class semi-synthetic pleuromutilin antibiotic. As a monotherapy offering a complete spectrum of coverage for the main CABP pathogens and with a low propensity for the development of bacterial resistance, XENLETA ® represents a critical step in addressing the growing global public health crisis of antimicrobial resistance (AMR) and supports the principles of antimicrobial stewardship. “Antimicrobial resistance, unfortunately, undermines the treatment paradigms of many infectious diseases globally, leading to poor patient outcomes and increased costs to healthcare systems,” said Brett Novak, Meitheal’s Senior Vice President of Commercial Operations. “XENLETA ® provides a unique and well-tolerated product profile for the more than five million annual cases of CABP in the U.S., where it has the potential to serve as a first-line monotherapy option in both the inpatient and outpatient settings. We are pleased that this agreement will allow us to unlock synergies with our existing franchises and deliver critical medicines that address large gaps in the antibiotic treatment landscape.” Global approvals of XENLETA ® in CABP are based on the results of two global, pivotal Phase 3 trials, LEAP 1 and LEAP 2, in which XENLETA ® met all primary endpoints. Meitheal recently added the first anti-infective to its portfolio through an exclusive commercialization agreement with HKF—CONTEPO™. Meitheal will leverage its new aligned-to-CONTEPO ™ marketing, sales, and medical science liaison teams to support the launch of XENLETA ® , which shares similar hospital call points. Meitheal will further establish practice-based support for key prescribers and patients that could benefit from XENLETA ® . “We are pleased to have acquired the rights to XENLETA ® and look forward to supporting Meitheal as it delivers this important medication to patients in the U.S.,” said Eric Tang, President of HKF. “We are committed to supporting Meitheal’s work to deliver accessible, sustainable, and innovative healthcare solutions and we remain focused on continuing to invest in the research, development, and commercialization of branded pharmaceuticals to achieve this goal.” HKF and its related entities have invested over $300 million in capital and research and development in recent years to support sustainable product supply across key focus areas, including branded biopharmaceuticals. The licensing agreement for XENLETA ® adds a third branded biopharmaceutical and first on-market branded product to Meitheal’s portfolio. ABOUT COMMUNITY-ACQUIRED BACTERIAL PNEUMONIA (CABP) Pneumonia is an infection of the lung that can be serious and fatal, especially among older adult patients with comorbidities. CABP is among the most common types of pneumonia, with five million cases in the U.S. each year. 1 In the U.S., CABP is the leading cause of infection-related death 2 and the fourth leading cause of hospitalization, 3 a setting where mortality rates are approximately 15% 4 . Certain bacteria that cause CABP have become resistant to one common antibiotic, macrolides, at a rate on average of 50%. 5 The U.S. FDA has also issued multiple warnings about the resistance of one current class of CABP treatments called fluoroquinolones. 6 Antimicrobial resistance (AMR) is a top global public health threat that creates challenges treating infections and performing medical procedures and increases the risk of death and disability. 7 Novel antibiotics that kill bacteria, including those that cause CABP, in a different way are essential to addressing AMR. 8 ABOUT XENLETA ® XENLETA ® (lefamulin acetate) is a first-in-class, semi-synthetic pleuromutilin antibiotic for systemic administration in humans. It is designed to inhibit the synthesis of bacterial protein, which is required for bacteria to grow. XENLETA ® ’s binding occurs with high affinity, high specificity, and at molecular sites that are different than other antibiotic classes. Two multicenter, multinational, double-blind, double-dummy, non-inferiority trials assessing a total of 1,289 patients with CABP demonstrated XENLETA ® ’s efficacy. In these trials, XENLETA ® was compared with moxifloxacin, and in one trial, moxifloxacin with and without linezolid. Patients who received XENLETA ® had similar rates of efficacy as those taking moxifloxacin alone or moxifloxacin plus linezolid. CONTRAINDICATIONS XENLETA ® is contraindicated in patients with known hypersensitivity to lefamulin, pleuromutilin class drugs, or any of the components of XENLETA ® . Concomitant use of XENLETA ® tablets with CYP3A substrates that prolong the QT interval is contraindicated. WARNINGS AND PRECAUTIONS QT Prolongation: Avoid use in patients with known QT prolongation, ventricular arrhythmias including torsades de pointes, and patients receiving drugs that prolong the QT interval such as antiarrhythmic agents. Embryo-Fetal Toxicity: May cause fetal harm. Advise females of reproductive potential of the potential risk to the fetus and to use effective contraception. Clostridioides difficile-associated Diarrhea: Evaluate patients who develop diarrhea. ADVERSE REACTIONS The most common adverse reactions associated with XENLETA ® Injection include administration site reactions, hepatic enzyme elevation, nausea, hypokalemia, insomnia and headache. The most common adverse reactions associated with XENLETA ® Tablets include diarrhea, nausea, vomiting, hepatic enzyme elevation. Please see Full Prescribing Information for more information.
