The rising rates of antimicrobial resistance have created an urgent need for antibiotics with activity against drug-resistant gram-negative pathogens (GNPs). Antibiotics such as carbapenems, which have historically been reserved for later lines of therapy, are being used earlier in treatment, placing additional pressure on the already-limited gram-negative infection (GNI) armamentarium. Despite the launch of antibiotics such as Avycaz / Zavicefta, Zerbaxa, Vabomere, Xerava, and Zemdri, unmet needs remain for additional effective treatment options. Commercial opportunities exist for emerging therapies with efficacy in patients with drug-resistant infections, especially those associated with high rates of mortality. However, the market is heavily genericized, and cost containment measures may limit commercial success.


  • What are the drivers and constraints in the HT-GNI market, and how will the market evolve over the forecast period? How will rising antibiotic resistance rates and the entry of new generics shape the market?
  • How large are the different GNI indications? What are the resistance rates to different classes of antibiotics across several pathogen species?
  • How will different emerging therapies targeting antibiotic-resistant pathogens address current unmet needs? What emerging therapies do infectious disease (ID) specialists consider as the most promising, and where will these therapies be used?
  • What attributes will emerging therapies need to improve on in order to compete with currently marketed products? What challenges will they face?
