CRE stands for carbapenem resistant Enterobacteriaceae, a family of bacteria difficult to treat because they have very high resistance to antibiotics. CRE infections usually happen to patients in hospitals and other healthcare settings. They have been categorised the highest threat level of ‘urgent’ by the US Centers for Disease Control and Prevention.1
The study, conducted by an independent Contract Research Organisation (CRO) in the USA, observed three groups of eight mice infected with drug resistant E. coli. Mice infected were then treated with Tigecycline, RECCE® 327 and No Treatment, respectively.
Tigecycline is a last line antibiotic used to treat bacterial infections. It was developed in response to growing rates of antibiotic resistance in bacteria such as E. Coli and Staphylococcus and was approved by the US FDA in 2005.
Based on “Health Scores” results indicated intravenous (IV) injection of RECCE® 327 antibiotic (70 mg/Kg) reduced illness in mice infected by intravenous and intra-kidney Carbapenem resistant Gram-negative (CRE) E. coli. (See chart below)
The above chart shows the average of the total of “Health Scores” in mice, using a range of 0 (healthy) to 13 (unhealthy), recorded at 8 hours, 18 hours and 24 hours, respectively after infection of the individual mice (n = 8 per group) with resistant Gram negative E. coli (4.71 x 107 bacteria). These results are detailed in the table below.
Also, results indicate IV injection of RECCE® 327 antibiotic (70mg/Kg), controlled weight-loss in mice infected by intravenous and intra-kidney Carbapenem-resistant Gram negative E. coli: The following Graph shows the average weight percentage loss at 24 hours.
These results are detailed in the table below.
RECCE® 327 is a synthetic compound currently being developed to treat sepsis (blood poisoning with a near term goal of filing an investigational new drug (IND) application with the US Food & Drug Administration (FDA) in 2017.
Recce Limited Executive Chairman Dr Graham Melrose said “This new pre-clinical data will potentially strengthen Recce’s IND submission for RECCE® 327 to be trialled in humans as a new class of antibiotic for a range of drug resistant infections. The promising results using RECCE® 327 in a mouse model for CRE resistant superbug Gram-negative E.coli warrant further investigation, based on the dosage administered”.

About Recce Ltd
Recce Ltd (ASX: RCE) is a world-leader in synthetic-polymer antibiotics. The RECCE® antibiotics have been synthesized by an extremely economic method. RECCE® antibiotics have shown in laboratory tests that they have continued activity against bacteria, including superbugs, even after repeated use. Recce is positioned to achieve milestones in both pre-clinical trials for FDA purposes, and the development of the manufacture of RECCE® 327.
The discovery of RECCE® 327’s in vitro capabilities against cancer and viruses (as well as bacteria-superbugs) has greatly increased the value of the Company’s technology, especially in view of the synergism between antibiotic/anti-cancer properties and anti-viral/anti-cancer properties.
Recce has granted patents in Australia, United States, Europe, Japan and China – giving it legal monopolies, and potential financial returns, from manufacture and distribution of its products in about 80% of the world’s pharmaceutical markets for antibiotics.
