Cempra to Present Late-Breaker on Solithromycin Reducing Inflammation in an Animal Model for Cancer Chemotherapy-Induced Lung Injury

Study Suggests Clinical Uses of Solithromycin Beyond Bacterial Infections

Presentation at the American Thoracic Society 2014 International Conference

CHAPEL HILL, N.C., March 27, 2014 (GLOBE NEWSWIRE) -- Cempra, Inc., (Nasdaq:CEMP) today announced a late-breaker presentation demonstrating that solithromycin reduced inflammation in an animal model for inflammatory lung disease at the American Thoracic Society (ATS) 2014 International Conference in San Diego.

Key facts:

  • Chemotherapeutic agents, such as bleomycin, have been associated with lung inflammation and fibrosis: http://www.ncbi.nlm.nih.gov/pubmed/15062597
  • Solithromycin, a fourth-generation macrolide, demonstrated superior anti-inflammatory activity compared to other macrolides in an animal model: http://www.ncbi.nlm.nih.gov/pubmed/?term=A+novel+macrolide+solithromycin+exerts+superior+anti-inflammatory+effect+via+NF-%CE%BAB+inhibition
  • This study, abstract A6586 (8:15 a.m. to 4:30 p.m. PDT, May 18, 2014); Area A, Poster Board #A127), investigated the ability of solithromycin to prevent lung inflammation and fibrosis in a bleomycin-induced lung inflammation and fibrosis model
  • The total numbers of inflammatory cells, particularly lymphocytes, neutrophils and eosinophils, were significantly reduced in solithromycin-treated mice compared to vehicle-treated mice
  • According to the study's authors, "A decrease in inflammatory cells could in the long term decrease lung fibrosis and longer term treatment studies are warranted. The results suggest that SOLI could be beneficial to prevent disease progression and development of pulmonary fibrosis in patients."


Prabhavathi Fernandes, Ph.D., president and chief executive officer of Cempra said, "Solithromycin is emerging as a molecule with an increasing list of possible therapeutic indications including diseases outside of bacterial infections. This study adds to the accumulating evidence that solithromycin may have utility in treating chronic inflammatory lung diseases such as, in this case, chemotherapy-induced lung inflammation and fibrosis and chronic obstructive pulmonary disease, or COPD, on which we have also conducted preclinical work. We are seeking to identify additional possible non-antibiotic uses outside of lung inflammation as well. Because of solithromycin's safety profile and clinical data to date, we believe that we could progress directly into Phase 2 development if we wish to move forward in one or more of these non-antibiotic indications."

About Cempra, Inc.

Founded in 2006, 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 (CEM-101) is in a Phase 3 clinical trial for community-acquired bacterial pneumonia (CABP) and is licensed to strategic partner Toyama Chemical Co., Ltd., a subsidiary of FUJIFILM Holdings Corporation, for certain exclusive rights in Japan. TAKSTA™ (CEM-102) is Cempra's second product candidate currently in a Phase 2 clinical trial for prosthetic joint infections. Both seek to address the need for new treatments targeting drug-resistant bacterial infections in the hospital and in the community. The company also intends to use its series of proprietary lead compounds from its novel macrolide library for uses such as the treatment of chronic inflammatory diseases, endocrine diseases and gastric motility disorders.
