This bill amends the Federal Food, Drug, and Cosmetic Act to allow the Food and Drug Administration (FDA) to approve an antibacterial drug or biological product that is intended to treat a serious or life-threatening condition only for treating a well-defined population of patients. To be approved, the antibacterial product must produce superior outcomes over available therapies in the well-defined patient population.

A product approved by this pathway must include in its prescribing information the population of patients expected to benefit from using the product and the method for identifying members of that population. The FDA must require each product to have a risk evaluation and mitigation strategy.

The Centers for Disease Control and Prevention must monitor changes to bacterial drug resistance and changes to patient outcomes caused by bacterial drug resistance.

Upon approval of antibacterial products, the FDA must identify susceptibility test interpretive criteria (the drug concentrations where a type of bacteria is categorized as susceptible, intermediate, or resistant) and update the criteria as needed based upon evidence of changes in patient outcomes.

To be eligible for an exclusivity period extension, a qualified infectious disease product must be demonstrated to produce superior outcomes over available therapies.
