CARB-X is funding The University of Queensland to develop a new drug targeted to low- and middle-income countries that would breathe new life into existing readily-available antibiotics in the fight against drug-resistance

UQ’s innovative Octapeptin drug would disable the bacteria’s protective wall, creating a path for antibiotics to enter the bacteria and kill them

(BOSTON: February 22, 2021) – CARB-X is awarding up to US$2.2 million to The University of Queensland’s (UQ) Institute for Molecular Bioscience (IMB), Brisbane, Australia, to expand its Octapeptin research program to develop a new drug designed for use in low- and middle-income countries (LMICs) where there are high levels of drug-resistant bacteria.

The new drug – engineered Octapeptin peptides that act as potentiators – would work by disrupting the protective cell membrane of drug-resistant Gram-negative bacteria so that existing antibiotics can once again work to kill the bacteria. The drug would be used in combination with antibiotics that are readily available in LMICs but that have become ineffective in the treatment of drug-resistant bacterial infections.

The LMIC-focused Octapeptin potentiator project is led by Associate Professor Mark Blaskovich, Dr. Alysha Elliott and Dr. Johannes Zuegg at UQ’s IMB. The new award is in addition to funding announced in 2020 of up to $10.86 million – the first-ever Australian project funded by CARB-X –  for the Octapeptin research program led by Professor Matthew Cooper and Dr. Karl Hansford, along with Dr. Blaskovich.

“New innovative approaches are urgently needed to treat deadly infections. CARB-X funds and supports a broad diversity of scientific approaches in development around the world,” said Erin Duffy, R&D Chief of CARB-X, a global non-profit partnership led by Boston University and dedicated to funding and supporting the development of innovative antibiotics, vaccines, diagnostics and other products to address antibiotic-resistant bacterial infections. “The UQ IMB project aims to reboot generic antibiotics that have become ineffective against Gram-negative bacterial infections in LMICs.  If successful, this approach could provide new treatment options in parts of the world where life-saving options are limited.”

‘Running out of time’

“We are running out of time to outsmart the most dangerous drug-resistant bacteria, and this funding will build on our existing CARB-X funded work developing a new antibiotic class, the Octapeptins,” Dr. Blaskovich, Director of the IMB Centre for Superbug Solutions, said. “We will harness this latest funding injection to investigate which existing antibiotics can be rejuvenated by combining them with compounds from the Octapeptin family.”

“The benefit is that we can potentially restore the use of cheap generic antibiotics that are widely used in LMICs, where there are high levels of drug-resistant bacteria,” Dr Elliott said. She added that with Octapeptins, there is potential to significantly reduce the amount of antibiotics required to treat an infection.

A similar scientific approach has been effective at extending the effectiveness of the beta-lactam class of antibiotics such as penicillin, revitalised by inhibitors that block the beta-lactamase enzymes that bacteria use to defend themselves from these antibiotics.

The new Octapeptin project is in the hit-to-lead phase. Early goals are to identify which types of antibiotics Octapeptins are best at helping, and which of two structural subclasses of Octapeptins are most promising with the best efficacy and least toxicity. The project also includes a capability enhancement to support several hospitals in countries such as Pakistan, Nepal and Nigeria to establish whole genome sequencing and molecular epidemiology protocols so that they can analyse different resistant strains using genetic sequencing onsite in their countries.

Dr. Blaskovich said the team plans to help researchers and health professionals collect and identify resistant bacteria, especially in remote areas, which will contribute to knowledge of how resistance develops.

CARB-X funding supports antibacterial R&D around the world

CARB-X receives its funding from the US Biomedical Advanced Research and Development Authority (BARDA), the Wellcome Trust in the UK, Germany’s Federal Ministry of Education and Research (BMBF), the UK Global Antimicrobial Resistance (AMR) Innovation Fund (GAMRIF), and the Bill & Melinda Gates Foundation. Funding contributions by GAMRIF are earmarked by CARB-X to fund projects that focus on specific antibacterial priorities, and the UQ IMB Octapeptin LMIC project is one such project. GAMRIF funding allocated to CARB-X is focused on innovative research and development in the field of AMR, specifically in underinvested areas for LMICs, where the burden of AMR is greatest.

The World Health Organization (WHO) estimates that 700,000 people die each year from drug-resistant infections, including 35,000 in the US and 33,000 in Europe. CARB-X funds only projects that target drug-resistant bacteria highlighted on the Centers for Disease Control and Prevention (CDC)’s Antibiotic Resistant Threats list, or the Priority Bacterial Pathogens list published by the WHO, with a priority on those pathogens deemed Serious or Urgent on the CDC list, or ranked Critical or High on the WHO list.

52 projects progressing in the CARB-X portfolio

The CARB-X portfolio is the world’s largest and most diverse antibacterial R&D portfolio with 52 active projects, including the UQ IMB Octapeptin program, focused exclusively on drug-resistant bacteria. CARB-X is investing up to $480 million in non-dilutive funding between 2016-2022 to support the early development of new antibiotics and other therapeutics, vaccines and other preventatives, rapid diagnostics. The goal is to support therapeutics projects through the early phases of development including Phase 1 so that they will attract additional private or public support for further clinical development and regulatory approval for use in patients.

Since its launch in 2016, CARB-X has announced 78 awards and has committed more than $285 million, with the potential of additional funds if project milestones are met. These funds are in addition to investments made by the companies themselves. The CARB-X pipeline will continuously evolve, as projects progress and others fail for a variety of reasons.
