About
The purpose of this study is to evaluate the potential effect and safety of two different doses of PZ-601 and to compare this with another antibiotic that is approved by the US Food and Drug Administration (also known as FDA) to treat adults with skin and skin structure infections.
Full description
PZ-601 is a novel investigational carbapenem antibiotic with an antimicrobial spectrum of activity that includes pathogens responsible for community-acquired bacterial infections as well as multidrug-resistant Gram-positive pathogens - MRSA and vancomycin-resistant enterococci. PZ-601 also has activity against Gram-negative organisms including cephalosporin and quinolone resistant Enterobacteriaceae as well as Bacteriodes fragilis and peptostreptococci. Based on the antimicrobial profile, PZ-601 is a potentially promising agent for the treatment of complicated skin and skin structure infections.

Concomitant therapy with medications known to be associated with QTc prolongation potential (eg, Class IA and Class III anti-arrhythmic agents)
History or significant cardiac disease defined by the following:
History of any hypersensitivity or allergic reaction to beta-lactam drugs such as carbapenems, penicillins, or cephalosporins
History of any hypersensitivity or allergic reaction to vancomycin or history of Red Man Syndrome
Any planned medical intervention or personal event that might interfere with the ability to comply with the study requirements
Any condition that, in the opinion of the principal investigator, would compromise the safety of the patient or the quality of the data
Life expectancy of less than 3 months from the time of enrollment
Use of an investigational drug or device (ie, a drug or device without an FDA approved indication) within the previous 30 days
