CHAPEL HILL, N.C., Dec. 22, 2015 (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 it has successfully completed enrollment of 250 patients in the United States and Australia for its Phase 3 trial in urogenital gonorrhea. Under a CRADA (Cooperative Research and Development Agreement) with the National Institute of Allergy and Infectious Diseases (NIAID), the Phase 3 trial has been amended to include up to an additional 60 patients, consisting of women and adolescents with culture-proven gonorrhea.
“We have already completed patient enrollment of the first 250 patients, the majority of whom were men,” said Prabhavathi Fernandes, Ph.D., president and chief executive officer of Cempra. “There is tremendous need for an effective, single dose, oral treatment such as solithromycin that can provide coverage for both gonococcus and chlamydia for the entire population at risk for these infections. We are pleased that the NIAID will be expanding this study to enroll the additional patient populations that could eventually be included for the label indication, should solithromycin be approved for the treatment of urogenital gonorrhea. This potential use could be an attractive secondary market, in addition to the primary indication we are seeking for the treatment of community-acquired bacterial pneumonia.”
Solithromycin as a single oral dose showed high efficacy in treating male and female patients in a Phase 2 trial in uncomplicated bacterial urethritis (Hook III EW et al. Clin. Infect. Dis. 61(7):1043-8 http://cid.oxfordjournals.org/content/early/2015/06/18/cid.civ478.abstract).
About Solitaire-U Phase 3 Clinical Trial
An oral solithromycin Phase 3 clinical trial, called Solitaire-U, is being conducted in patients with uncomplicated Neisseria gonorrhoeae and chlamydia infections in both Australia and the U.S. It has completed enrollment of 250 evaluable patients, the majority of whom are men, with culture-proven Neisseria gonorrhoeae. Solitaire-U is a randomized, two-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. A planned amendment to the protocol will enroll up to an additional 60 patients, consisting of women and adolescents.
There is an urgent need for new antibiotics to treat gonorrhea, which is easily transmitted and the second most commonly reported notifiable infection in the US. CDC has declared gonorrhea to be among the top 3 urgent threats in the United States http://www.cdc.gov/drugresistance/threat-report-2013/). The most recent guidelines from the CDC for treatment of gonorrhea in the United States (http://www.cdc.gov/std/gisp) recommends only one treatment regimen, which is dual therapy with ceftriaxone and azithromycin. If solithromycin is approved for this indication, it could provide a convenient oral treatment for patients.
