Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Primary objective: To compare the event rate of CDI in groups assigned to ACAM-CDIFF™ vaccine versus placebo in the 9 week period after the third dose of the study vaccine in subjects with first episode of CDI receiving antibiotics standard of care.

Secondary objective: To evaluate the safety of all dose groups of ACAM-CDIFF™ vaccine versus placebo in subjects with first episode of CDI receiving antibiotics standard of care.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is designed primarily to obtain information on the preliminary efficacy, safety and immunogenicity of ACAM-CDIFF™ vaccine, as compared to placebo in subjects who are experiencing their first event of CDI and are being treated with the antibiotic standard of care. This study will be conducted in the United States and United Kingdom. Adult subjects with limited chronic disease, who are currently receiving treatment for their first episode of CDI will be enrolled in this trial.
