General Guidelines

Clinical trials "are designed to add to medical knowledge related to the treatment, diagnosis, and prevention of diseases or conditions. Some common reasons for conducting clinical studies include: Evaluating one or more interventions…for treating a disease, syndrome, or condition…Finding ways to prevent the initial development or recurrence of a disease or condition…Evaluating one or more interventions aimed at identifying or diagnosing a particular disease or condition…Examining methods for identifying a condition or risk factors for that condition…Exploring and measuring ways to improve the comfort and quality of life of people with a chronic illness through supportive care" (

Your LBCT submission must meet the following criteria for ASN consideration:

  • Submit as much data as possible. The late-breaking clinical trials committee will make their decisions and assignments based on the information submitted.
  • Do not submit multiple abstracts on the same trial - only one abstract submission per trial.
