Clostridium difficile bacteria can be a cause of significant diarrheal disease, particularly
in people who have taken potent antibiotics. When C. difficile multiplies within the colon,
it produces two toxins that cause inflammation and resultant abdominal pain, fever and
diarrhea. Current treatment of mild to moderate disease is with immediate release
metronidazole, an antibiotic that kills C. difficile. Dr. Reddy's Laboratories has developed
a delayed release form of metronidazole to release just before the colon to increase the
concentration of antibiotic in the colon to improve the effectiveness of metronidazole
treatment and potentially to allow less whole body exposure to the antibiotic.
This study will measure the amount of metronidazole in the blood and stool of patients with
C. difficile associated diarrhea (CDAD) to confirm that the new formulations are releasing
the antibiotic as designed, immediately before the colon.

Inclusion Criteria: 1. Male and female patients 18 years of age or older 2. Mild to moderate C.difficile associated diarrhea (CDAD) with a positive stool C.difficile toxin (by ELISA). 3. Either a first episode of CDAD or a first recurrence (patients with more than 1 recurrence are not eligible) 4. Greater than 3 watery or unformed bowel movements in the prior 24 hours 5. Females of child bearing potential having a negative pregnancy test and taking adequate birth control measures. 6. Patients should not consume alcohol at least 12 hours prior to dosing (i.e. in-house monitoring) and until 48 hours after the last dose of drug administration (until Day 14). 7. Able to comprehend and give informed consent for the study and able to adhere to study schedules and protocol requirements. Exclusion Criteria: 1. Known prior history of hypersensitivity to metronidazole or other nitroimidazole derivatives 2. Life expectancy = 60 days 3. Sepsis, severe sepsis, or septic shock 4. Signs or symptoms of peritonitis, megacolon or ileus 5. History of ulcerative colitis or Crohn's disease 6. Oral or parenteral antibiotic therapy with metronidazole or vancomycin or other drugs effective in treating DCAD (e.g., bacitracin, fusidic acid) within the 1 week prior to enrollment 7. Recent history of significant drug or alcohol abuse within 1 year 8. Any findings on physical examination, medical history, 12-lead ECG or clinical laboratory tests which, in the judgment of the Principal Investigator, would exclude patients from participating in the study 9. Patients with history of blood dyscrasias, porphyria and active non-infectious disease of the central nervous system 10. Patients with history of rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption 11. Pregnant or lactating female patients 12. Participation within 30 days before the start of this study in any experimental drug or device study, or currently participating in a study in which the administration of investigational drug or device within 60 days is anticipated 13. Unable to participate in the study for any reason in the opinion of the Principal Investigator |
