AzurRx BioPharma Announces Positive Preclinical Data with AZX1103

  • Company is developing AZX1103 for the prevention of nosocomial infections induced by administration of several classes of antibiotics
  • AZX1103 shown to be safe and biologically active in a well-established pre-clinical model 

BROOKLYN, NY, USA I April 18, 2018 I AzurRx BioPharma Inc. (NASDAQ:AZRX) (“AzurRx” or the “Company”), today announces positive preclinical results for AZX1103, a b-lactamase enzyme combination product being developed for the prevention of hospital-acquired gastro-intestinal infections.

AZ1103 is designed to be a complementary treatment for patients receiving antibiotics in the hospital setting. The results from the preclinical studies showed that AZX1103 had activity and degraded amoxicillin in the presence of clavulanic acid in the upper GI tract in the Gottingen minipig model.

“The data from these studies are very encouraging, showing AZ1103 to be safe and capable of inactivating amoxicillin, a member of the widely used class of b-lactam antibiotics,” said Thijs Spoor, CEO of AzurRx.  “We are developing AZX1103 to prevent hospital acquired infections, such as those caused by Clostridium difficile (C. diff) and vancomycin resistant enterococcus (VRE). The next steps in this program will be to conduct toxicity studies in animals with the goal of receiving the regulatory approvals to enter the clinic.”

The series of preclinical studies investigated oral delivery of AZ1103 using three different capsule formulations: immediate-release, enteric-delivery or colonic-delivery. In all three formulations and at all doses tested, AZ1103 appeared to be well tolerated.  No side effects were observed and the animals showed normal behavior, standard food consumption and body weight gain. There was no evidence of acute toxicity, and no severe immunoallergic reactions were seen at doses of up to 180mg/day. The favorable safety profile is partly the result of AZ1103 not being absorbed by the gut and entering the bloodstream. This property was confirmed by ELISA testing, which did not detect
the enzyme in AZ1103 in the animal sera.  

About AZX1103, An Enzymatic Combination for Prevention of Hospital Infections

AZX1103 is a b-lactamase enzyme combination product of bacterial origin for the prevention of hospital-acquired infections (known as nosocomial infections) and antibiotic-associated diarrhea (AAD) caused by resistant bacterial strains induced by parenteral administration of several antibiotic classes, including the b-lactams. AZ1103 is not absorbed in the gut, meaning that it will not disrupt the activity of antibiotics that are being administered IV to treat severe infections. However, AZ1103 can inactivate b-lactam antibiotics once they reach the large intestine, thus preventing the harmful disruptions to the gut microbiome that lead to diarrhea.

The Centers for Disease Control, (CDC) has estimated that approximately 1.7 million hospital-associated infections (i.e. ~5% of the number of hospitalized patients), cause or contribute to 99,000 deaths each year in the U.S., with the annual cost ranging from $4.5 - $11.0 billion.
