Study results to be presented at 2008 ICAAC/IDSA Joint Meeting
ROCKVILLE, Md., Oct. 28 /PRNewswire/ -- Sequella, Inc., a clinical-stage biopharmaceutical company focused on commercializing products to treat infectious diseases of epidemic potential, announces the successful demonstration of synergistic activities and improvement of minimal inhibitory concentration (MIC) resulting from in vitro combination studies of Sequella lead TB drug candidate, SQ109, and Tibotec's lead TB drug candidate, TMC207. Both drug candidates are currently undergoing human clinical studies.
Results from these studies were presented on October 28th at the Interscience Conference on Anti-Microbial Agents and Chemotherapeutics (ICAAC) and Infectious Disease Society of America (IDSA) joint meeting in Washington, DC.
The collaboration between Sequella and Tibotec was designed to investigate in vitro interactions of SQ109 for synergistic, additive, or antagonistic activity in the presence of TMC207, using a number of clinical and laboratory strains of both drug sensitive and drug resistant M. tuberculosis (MTB). In vitro interactions investigated included synergy studies, rate of killing, post antibiotic effect and intracellular activity against MTB in macrophages.
There were no antagonistic activities observed in any combination studies. SQ109 and TMC207 in combination were either synergistic or additive with the various MTB strains and showed increased rate of killing, enhanced post antibiotic effect and intracellular killing activity. Results showed that the SQ109 and TMC207 drug combination was extraordinary potent, with greater than 90% kill of MTB as early as 1 day after drug combination exposure.
Dr. Carol Nacy, CEO of Sequella said, "We are very pleased to be
collaborating with Tibotec, a world renowned product development
organization, and we look forward to our continuing partnership to examine
these important drug synergies in animal models
