Note: This data visualization was originally published in March 2017.
As of December 2019, an estimated 30 new nontraditional products with the potential to treat or prevent serious bacterial infections were in clinical development.
The below interactive resource—based on publicly available information and informed by external experts and company communication—focuses on the nontraditional products currently in the clinical development pipeline. To view subsets of products, use filter options below or click on corresponding sections of the pie charts.
While antibiotic innovation—finding and designing new types of antibiotics and improving existing drugs—remains essential to combating antibiotic resistance, “outside-the-box” approaches to preventing and treating bacterial infections are also needed. Such nontraditional approaches encompass a variety of products.

Note: The following drugs have been removed from the pipeline. Removed
candidates will be included in future updates if development resumes:
June 2019: S. pneumoniae next generation vaccine
(GSK-2189241A) was discontinued, according to a press release from the
company.
December 2018: SA4Ag was removed because development was discontinued,
according to a press release from the company.
June 2018: ASN100, GEN 004, Group B Streptococcus vaccine, and
VLA84 (IC84) were removed because they were no longer included in the
research and development pipeline on the company’s website.
September 2017: Shigamab and Cdiffense were removed because they were
no longer included in the research and development pipeline on the
company’s website.
This collection page was updated in December 2017 with new content.
Drug-resistant bacteria, or superbugs, present a serious and worsening threat to human health. A majority of doctors have encountered patients with infections that do not respond to available treatments, and when new drugs come to market bacteria can quickly develop resistance. According to a report from the Centers for Disease Control and Prevention, 2 million Americans acquire serious infections caused by antibiotic-resistant bacteria each year, and at least 23,000 die as a result. A sustained and robust pipeline of new antibacterial drugs and novel therapies is critical to ensure that new interventions keep pace with these evolving pathogens.
