Our Technology

Helicobacter pylori has evolved alongside humans in the stomach for the past 60,000 years.1 To survive in this niche, H. pylori modulates the immune system of its host.

Extensive epidemiological data support a relationship between the precipitous decrease in the incidence of H. pylori infection in developed countries and a concomitant rise in allergic disease of epidemic proportions. Paediatric allergy frequently manifests in the first few months of age as atopic dermatitis (also known as eczema) and may progress to include food allergies, allergic asthma, allergic rhinitis and other allergic conditions.

Several research groups, including Ondek’s scientists, have demonstrated experimentally that H. pylori modulates the host’s immune system to protect against the allergic response.

ImmBALANCE® is a patented therapeutic candidate in development for the management of paediatric allergy. Our product, ImmBALANCE®, is a killed cell-free form of a proprietary strain of H. pylori that has been shown to protect against allergy in animal models.

Ondek ImmBALANCE

ImmBALANCE® protects mice from developing allergic asthma. Independent studies confirmed that mice treated with a 25mg/kg dose of killed bacteria (green bar) had a lower allergic response compared to positive control mice (dark grey bar). The killed bacteria produced a similar protective effect to live bacteria (blue bar). These responses were similar to the negative control mice (light grey bar). Studies showed statistically significant protection from allergy in mice treated with either live or killed bacteria.

Ondek® has developed a fermentation process that allows us to grow large volumes of a proprietary strain of the bacteria. We then kill and process the bacteria in a way that retains its immunomodulatory properties and meets the regulatory requirements for pharmaceutical drug development.

Fermentation Process

Ondek is developing ImmBALANCE® to reduce the incidence of childhood allergy. Eczema and food allergies are the first signs of allergic disease in children. ImmBALANCE® will initially be used to reduce food allergy and disease severity of eczema in infants.

Eczema is an allergic disorder affecting 11% of children in the USA and >20% in some other developed countries, including Australia.2 Infants with moderate to severe eczema have a greater than 50% risk of manifesting food allergies at 12 months of age, and greater risk of developing asthma and allergic rhinitis later in life.3, 4, 5 Further clinical trials will explore the potential of early intervention with ImmBALANCE® to prevent individuals at higher risk from developing allergies later in life.

ImmBALANCE® will be orally administered and may be formulated as a powdered product that can be dissolved in drinks or foods or, as tablets or capsules. It is envisaged that daily dosing for specified periods will prove most effective.
