Breakthrough technology combines engineered bacterial viruses and antibacterial protein to inactivate bacterial DNA
(BOSTON: April 19, 2021) – CARB-X is funding Phico Therapeutics, in Cambridge, UK, to develop a new intravenous engineered bacteriophage drug to treat ventilator-associated pneumonia caused by Pseudomonas aeruginosa, a serious problem in hospitals, intensive-care units and health-care settings. P. aeruginosa is one of the top three antibiotic-resistant bacteria listed by the World Health Organization (WHO) as ‘priority pathogens’ posing the greatest threat to human health.
The CARB-X award provides up to $5.3 million to support preclinical development of Phico’s SASPject PT3.9 project, plus up to $12.86 million more if the project progresses successfully through safety to Phase 1 first-in-human clinical studies, subject to available funding.
Phico’s SASPject technology is ground-breaking in that it uses engineered bacterial viruses (bacteriophages) combined with antibacterial small acid-soluble spore proteins (SASPs) to precisely target the P. aeruginosa bacteria and inactivate the bacteria’s DNA, stopping them from reproducing and spreading. Additionally, SASPs are unaffected by the sequence of bacterial DNA, making it unlikely that bacteria could develop resistance, and are therefore effective against multidrug-resistant bacteria.
“Phico’s innovative approach delivers the antibiotic effect of SASPs by using engineered bacteriophages to precisely target P. aeruginosa infections,” 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 products to address antibiotic-resistant bacterial infections. “This approach has the potential to target the bacteria without damaging other cells or contributing to the rise of resistance. If successful, this new intravenous drug could transform the way patients with ventilator-associated pneumonia are treated in hospitals, and save lives.”
Patients on ventilators in hospitals and intensive-care units settings often develop pneumonia, which can be life-threatening particularly among intensive-care patients. The US Centers for Disease Control and Prevention (CDC) estimates that in 2017, multidrug-resistant P. aeruginosa caused 32,600 infections in US hospitals, and 2,700 patients died as a result. P. aeruginosa is also a significant problem in low- and middle-income countries (LMICs); Phico aims to produce a therapy that is accessible to resource-poor settings.
Dr. Heather Fairhead, Phico Founder and CEO, said: “To receive funding from CARB-X is important validation for our SASPject technology platform and its potential in fighting bacterial resistance. It has been awarded at the end of a due diligence process which reinforces the credibility of the company and our team – I am delighted to now look forward to progressing our lead product to clinical trials and developing a product pipeline that will advance the science of antibacterial therapy and in time, save millions of lives round the world.”

Supporting global innovation to address antibiotic resistance
CARB-X is investing up to $480 million in non-dilutive funding between 2016-2022 to support the early development of new therapeutics, preventatives and rapid diagnostics.
The CARB-X portfolio is the world’s largest and most diverse antibacterial R&D portfolio with 55 active projects focused exclusively on drug-resistant bacteria. The goal is to support products through the early phases of development 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 84 awards worth more than $318 million in 11 countries, with the potential of additional funds if project milestones are met, subject to available funding.
A non-profit partnership, CARB-X receives its funding from the US Biomedical Advanced Research and Development Authority (BARDA), the Wellcome Trust, the UK Global Antimicrobial Resistance Innovation Fund (GAMRIF), Germany’s Federal Ministry of Education and Research (BMBF), and the Bill & Melinda Gates Foundation. The funding contributions from GAMRIF are earmarked by CARB-X to fund projects that focus on specific antibacterial priorities, and the Phico 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 neglected and underinvested areas for low- and middle-income countries (LMICs), where the burden of AMR is greatest.
Each year, an estimated 700,000 people die each year from antibiotic-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 CDC 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 Critical or High on the WHO list.
CARB-X funding for this project is supported by the Cooperative Agreement Number IDSEP160030 from ASPR/BARDA and by awards from the Wellcome Trust, Germany’s Federal Ministry of Education and Research (BMBF), and the UK Global AMR Innovation Fund (GAMRIF).

About Phico Therapeutics
Phico Therapeutics (Phico) is a biotechnology company developing engineered phage technology as the basis of a new generation of antibiotics to overcome antibacterial resistance, particularly those caused by multi-drug resistant bacteria.
Phico’s SASPject™ platform technology utilises engineered bacterial viruses, or phages, to deliver a gene encoding a unique antibacterial small acid-soluble spore protein (SASP) that inactivates bacterial DNA. This stops the bacteria from metabolising or reproducing, whilst the SASP remains unaffected by the sequence of the bacterial DNA, including mutations, making resistance unlikely to develop. SASPject can target any chosen bacteria including those that are treatment resistant.
Founded in Cambridge, UK, by Dr Heather Fairhead, Phico is building an innovative intravenous antibacterials pipeline focused on serious infections with few existing treatment options and targeting key superbug threats including a Pseudomonas aeruginosa, Klebsiella pneumoniae and Escherichia coli. The company has previously received backing from independent investors, the Wellcome Trust and UK Government grants, and has a clear path to take lead intravenous product, P. aeruginosa targeted, SASPject PT3.9 through a study in patients. www.phicotx.co.uk/
SASPject™ is a pan-spectrum antibacterial technology that can target selected bacterial species by using engineered bacteriophages. SASPject™ works by injecting a gene that encodes small acid-soluble spore proteins, or SASPs, directly into the targeted bacteria. The injected gene then produces SASPs, which bind to bacterial DNA and inactivate it. SASPs “turn off” DNA so the targeted bacterial cell cannot metabolise or reproduce. The immune system can then remove the bacteria from the body. SASPs bind to all bacterial DNA, irrespective of the sequence of that DNA. Spontaneous mutations in DNA, or the import of new DNA that gives new characteristics to the bacterial cell, are key ways in which bacteria develop resistance to antibiotics. Neither of these strategies affects the ability of SASP to bind to and inactivate bacterial DNA.
