Cempra Initiates Phase 3 Clinical Trial in Patients With Uncomplicated Gonorrhea Infection
CHAPEL HILL, N.C., Aug. 12, 2014 (GLOBE NEWSWIRE) -- Cempra, Inc., (Nasdaq:CEMP) today announced the initiation of a Phase 3 clinical trial, called Solitaire-U, of a single 1000 mg dose of oral solithromycin in patients with uncomplicated Neisseria gonorrhea and chlamydia infections.
The trial is being conducted in Australia and the U.S. and will enroll approximately 300 patients in a randomized 2-arm study with a single oral dose of 1000 mg of solithromycin compared with the standard of care, 500 mg of ceftriaxone administered intramuscularly and 1000 mg of oral azithromycin.
The Phase 2 trial of single oral doses of solithromycin demonstrated 100 percent efficacy in all culture proven cases of uncomplicated gonococcal infections at all body sites. http://www.cempra.com/common/pdf/abstracts/Abstract_ECCMID%202013_Soli%20for%20gonorrhea_Oral%20Pres.pdf
Magnus Unemo, Ph.D., Associate Professor, Medical Microbiology and Molecular Biology, Örebro University Hospital in Sweden and senior researcher and Director of the WHO Collaborating Centre for Gonorrhoea and Other Sexually Transmitted Infections, said, "Prevalence of drug-resistant gonococci is continuing to grow as a global public health threat. New options are needed to combat it and few particularly oral antibiotics are in advanced development."
Marcus Chen, PhD., Adjunct Associate Professor, Monash University and principal investigator for the Solitaire-U, said, "This clinical trial is an important one for treating gonorrhea because of the increasingly limited options we have for our patients. An oral, single dose option that is effective against increasingly resistant gonorrhea and also effective against chlamydia would be an important addition to the armamentarium we have available for controlling gonorrhea."
- The Centers for Disease Control (CDC) estimates that over 800,000 cases of gonorrhea occur in the U.S. each year. http://www.cdc.gov/std/gisp2012/default.htm.
- The U.S. Food and Drug Administration (FDA) designated solithromycin as a Qualified Infectious Disease Product (QIDP) for this indication.
- World Health Organization and the CDC have recently included gonorrhea on their lists of top pathogens of concern, due to increasing resistance.
- The majority of the 300 patients will be enrolled in Australia, supported by the Sexual Health Clinics in Melbourne and Sydney. One center in the U.S. will enroll patients.
- Phase 3 trial costs will be covered in part by the established clinic infrastructure in Australia.

Prabhavathi Fernandes, Ph.D., president and chief executive officer of Cempra, said, "The Centers for Disease Control has listed gonorrhea infection among the urgent threat pathogens. Solithromycin is one of the few oral antibiotics that has shown significant promise as a treatment for uncomplicated gonorrhea based on a Phase 2 study. We look forward to presenting the results of the Phase 3 trial and expect to submit this data as the second indication with the data from our two ongoing CABP studies, Solitaire-Oral and Solitaire-IV."
