The journal is a peer-reviewed journal developed to publish original, innovative and novel research articles resulting in negative results. This peer-reviewed scientific journal publishes a theoretical and empirical paper that reports the negative findings and research failures in pharmaceutical field. Submissions should have a negative focus, which means the outputs of research yielded in negative results are being given more preference.
