— Both pivotal Phase 3 studies now published in leading infectious disease journals —
— FDA and EMA currently reviewing marketing applications for solithromycin for CABP in U.S. and EU —
CHAPEL HILL, N.C., Aug. 25, 2016 (GLOBE NEWSWIRE) -- Cempra, Inc. (Nasdaq:CEMP), a clinical-stage pharmaceutical company focused on developing antibiotics to meet critical medical needs in the treatment of bacterial infectious diseases, today announced the publication of its pivotal Phase 3 study, SOLITAIRE-IV, comparing the efficacy and safety of intravenous-to-oral solithromycin to intravenous-to-oral moxifloxacin for the treatment of community-acquired bacterial pneumonia (CABP) in Clinical Infectious Diseases.
As previously reported, the SOLITAIRE-IV study demonstrated that solithromycin was non-inferior to moxifloxacin, a potent respiratory fluoroquinolone, for treatment of CABP, meeting its primary endpoint that was aligned with FDA guidance.
Cempra’s other pivotal Phase 3 study with solithromycin, SOLITAIRE-ORAL, which evaluated the efficacy and safety of oral solithromycin versus oral moxifloxacin for the treatment of CABP, also met its primary non-inferiority endpoint and was published in Lancet Infectious Diseases in February 2016.
“The SOLITAIRE-IV study highlights the potential for physicians to transition CABP patients from IV to oral solithromycin, without needing to add or change drug classes. This type of approach could have significant clinical and public health benefits,” said Thomas M. File, M.D., from Northeast Ohio Medical University and lead author of the study.
“If approved, solithromycin may help address the urgent problem of antibiotic resistance and provide physicians with a new, potent macrolide monotherapy option that currently does not exist when treating patients with CABP,” File added.
According to the U.S. Centers for Disease Control and Prevention (CDC), CABP is the leading cause of death due to infectious disease in the United States, killing more than 53,000 people annually. Streptococcus pneumoniae (S. pneumoniae) is the leading cause of bacterial pneumonia in the U.S. and drug-resistant S. pneumoniae is responsible for 1.2 million infections a year, according to the CDC.
“Both of Cempra’s Phase 3 pivotal trials with solithromycin met their primary endpoint and we are pleased that both studies have now been published by two of the leading infectious disease journals in the world,” said Prabhavathi Fernandes, Ph.D., president and chief executive officer of Cempra.
“We believe these studies provide strong data supporting the safety and efficacy associated with solithromycin and we look forward to our ongoing interactions with regulators to achieve approval for this important new antibiotic, which could help to address the growing problem of antibiotic resistance,” Fernandes added.
Solithromycin is a highly potent next-generation macrolide which has activity against most macrolide-resistant CABP pathogens. In vitro and in vivo studies have shown potent activity against S. pneumoniae as well as an extended spectrum of activity against community-acquired methicillin-resistant S. aureus (CA-MRSA), streptococci, haemophilus, enterococci, Mycobacterium avium and in animal models of malaria. It is also active against atypical bacteria, such as legionella, chlamydia, mycoplasma and ureaplasma, and against gonococci and other organisms that cause genitourinary tract infections. It is eight to 16 times more potent than azithromycin against many bacteria and is active against azithromycin-resistant strains. The activity of solithromycin against resistant strains is driven by its ability to interact with three sites on the bacterial ribosome, compared to the single binding site of first- and second-generation macrolides.
About Community-Acquired Bacterial Pneumonia
Community-acquired bacterial pneumonia (CABP) is the number one cause of death from an infection, particularly in the very young and in the elderly. CABP is one of the most commonly diagnosed bacterial infections in the U.S. with five to 10 million cases per year. Although many strains of the primary CABP pathogen, Streptococcus pneumoniae, are resistant to currently-approved macrolides, this class of antibiotic remains among the most commonly prescribed antibacterial drugs for CABP in both hospital and community settings. Due to the rising threat of microbial resistance, along with concerns over antibiotic tolerability and impact on intestinal microflora, new CABP treatments are needed. Antibiotic resistance is a complex, emerging problem globally with potentially devastating consequences for public health.
About Cempra, Inc.
Cempra, Inc. is a clinical-stage pharmaceutical company focused on developing antibiotics to meet critical medical needs in the treatment of bacterial infectious diseases. Cempra's two lead product candidates are currently in advanced clinical development. Solithromycin has been successfully evaluated in two Phase 3 clinical trials for community-acquired bacterial pneumonia (CABP) and applications for approval for both intravenous and oral capsule formulations have been accepted for review by the FDA and the EMA. Solithromycin is licensed to strategic commercial partner Toyama Chemical Co., Ltd., a subsidiary of FUJIFILM Holdings Corporation, for certain exclusive rights in Japan. Solithromycin is also in a Phase 3 clinical trial for uncomplicated urogenital urethritis caused by Neisseria gonorrhoeae or chlamydia. Cempra is contracted with BARDA for the development of solithromycin for pediatric use. Three formulations, intravenous, oral capsules and a suspension formulation are in a Phase 1b trial in children from birth to 17 years of age. Fusidic acid is Cempra's second product candidate, which is being developed for acute bacterial skin and skin structure infections (ABSSSI) and is also in an exploratory study for chronic oral treatment of refractory infections in bones and joints. Both products seek to address the need for new treatments targeting drug-resistant bacterial infections in the hospital and in the community. Cempra has also synthesized novel macrolides for non-antibiotic uses such as the treatment of chronic inflammatory diseases, endocrine diseases and gastric motility disorders. Cempra was founded in 2006 and is headquartered in Chapel Hill, N.C. For additional information about Cempra please visit www.cempra.com.
