CARB-X 2020-21 annual report: CARB-X surpasses all goals in first five years in combatting antibiotic resistant-bacteria

CARB-X continues to prepare the world against antibiotic-resistant bacteria

(BOSTON: October 12, 2021) – CARB-X closed its fifth fiscal year on July 31, 2021 with US$361 million awarded to 92 projects funding since inception. In its latest fiscal year, CARB-X invested in 25 new projects across all three pillars – preventatives, diagnostics, and therapeutics. This year saw two more successful graduations from the portfolio, four more First-in Human programs launch, and several strategic augmentations of the portfolio including in the areas of: gonorrhea, bacteriophage, vaccines, peptides and polymyxins, and anti-virulence factors.

“In our fifth year, we augmented our portfolio along many themes, including non-traditional therapeutics, where we can simultaneously drive individual projects towards meaningful products and answer key questions that unlock value more generally for these new modalities,” said Erin Duffy, PhD, Chief of Research and Development at CARB-X, a non-profit global partnership supported by Boston University.

These achievements and more are highlighted in CARB-X’s 2020-2021 Annual Report published today. CARB-X continued to fulfill its mission to accelerate a diverse portfolio of innovative antibacterial products towards clinical development and regulatory approval with funding, expert support and cross-project initiatives.

Kicked-off towards the end of the prior fiscal year, CARB-X advanced ecosystem understanding of AMR product development through new cross-project initiatives in year five. These include early evaluation of pre-existing resistance risk for therapeutics or antigenic variability for preventatives, consistent assessment of key safety risks and improved animal models of infection.

In year five, CARB-X introduced product developers from two new countries into the portfolio: Italy and Denmark, raising the collective number of countries to 12. Together with partners, CARB-X also launched the world’s first practical guidance on strategies and activities to support Stewardship and Access for companies bringing new antibacterial products to market.

At year end, CARB-X had 60 active projects in portfolio, including 19 antibiotics with novel classes, 16 non-traditional therapeutics, 12 vaccines and preventatives, 12 rapid diagnostics, and one unique enhancement to an existing antibiotic class.

Over the course of five years, over 1,160 applications were submitted and reviewed from all eight funding rounds. These applications represented innovation from 39 countries on five continents. Furthermore, of the 92 projects that entered the CARB-X portfolio since 2016, 54 invention disclosures were filed – 36 for therapeutics, 6 for preventatives and 12 for diagnostics. This is yet another indicator of the sheer breadth of innovation accelerating at CARB-X. Since inception, CARB-X’s portfolio has supported nine projects through Investigational New Drug/IND-equivalent approvals, ten projects in Phase 1 development, of which eight included First-in-Human activities. In total, nine projects have graduated from the portfolio.

“We’ve accomplished so much in just five years and the work continues,” said Kevin Outterson, Executive Director of CARB-X. “As we forge ahead to rapidly and accurately diagnose patients with antibiotic-resistant infections, strengthen our antibiotic arsenal, and prevent infection altogether, it is paramount that we continue to engage with global partnerships to advance the science, and increase access, and promote good stewardship practices.”
