PRETECT combines the words pretreatment, and protection, for oncology and inflammatory conditions.

A major but often-overlooked medical issue is discontinuation or nonadherence to treatment. Dose reductions and drug discontinuations/nonadherence are one of the biggest reasons for treatment failure and treatment resistance.

To address this problem, EpicentRx designed the first-in-class NLRP3 inhibitor and Nrf2 upregulator, RRx-001, and its derivatives with “pretection” in mind, that is RRx-001 and its derivatives protect or shield normal tissues from the side effects of other therapies when administered as a pretreatment. Based on this pretection mechanism, RRx-001, which is currently in Phase 3, has been awarded Fast Track designation for the treatment of severe oral mucositis in head and neck cancer. The hoped-for result of pretection is better tolerability, improved convenience, cost effectiveness, and adherence to treatment with lower rates of treatment resistance and failure in cancer and several neurodegenerative conditions.

An integral part of the pretection mechanism is inhibition of the NLRP3 inflammasome, illustrated below.

The Inflammasome

Regulating chronic inflammation

The NLRP3 inflammasome kickstarts and perpetuates chronic inflammation, a hallmark of most major diseases, including cancer, through the production of the pro-inflammatory cytokines, IL-1β, and IL-18.

“The direct inhibition of the inflammasome by nibrozetone (RRx-001) has the potential to prevent and treat several chronic inflammation driven diseases, which is a huge opportunity and very exciting.”

The neuroprotective effects of RRx-001

With funding from The Michael J. Fox Foundation for Parkinson’s Research and Shake it Up Australia, and led by Dr. Richard Gordon at the Queensland University of Technology (QUT) in Brisbane, Australia, RRx-001 is under investigation as an inflammasome inhibitor and Nrf2 upregulator that may reduce or reverse symptoms of Parkinson’s and other neurodegenerative diseases.

Control inflammation & control the disease

RRx-001 inhibits the inflammasome

The Inflammasome is responsible for activation of inflammatory responses. With chronic inflammation tissue destruction that occurs outpaces the regeneration of damaged tissues. Eventually, over time, the normal function of these tissues is reduced or lost. In chronically inflamed tissues, which may result from unresolved sources of foreign bodies, irritants or infections, the inflammasome fuels an inflammatory response for weeks to months or even years, resulting in a range of metabolic, neurological, autoimmune disorders as well as in the initiation of cancer.
The Answer: AdAPT-001 programs infected cancer cells to produce a TGFβ “trap” molecule that is designed to neutralize TGFβ within the infected tumor. Eliminating the t-cell silencing TGFβ protein allows for the immune system to remain activated against cancer, making AdAPT-001 unlike any other immunotherapy.
AdAPT-001 doesn’t just create a cancer targeted infection, it produces a proprietary TGFβ “trap” protein to eliminate this tumor defense mechanism and allow for sustained immune response against cancer – alone or in combination with immune checkpoint inhibitors.
