Aside from the AditxtScore, this interested me!
I'm not saying $ADTX is buying or merging with Todos or the spin off of Todos' COVID-19 arm, I am saying this is interesting and I wonder if ESS and this ADi could be used in piggy back studies?


We have an exclusive worldwide license for commercializing this nucleic acid-based technology (which is currently at the pre-clinical stage), named Apoptotic DNA Immunotherapy™ (ADi™), which utilizes a novel approach that mimics the way the body naturally induces tolerance to our own tissues (“therapeutically induced immune tolerance”). While immune suppression requires continuous administration to prevent rejection of a transplanted organ, induction of tolerance has the potential to retrain the immune system to accept the organ for longer periods of time. Thus, ADi™ may allow patients to live with transplanted organs with significantly reduced immune suppression. ADi™ is a technology platform which we believe can be engineered to address a wide variety of indications.

We are developing ADi™ products for organ transplantation including skin grafting, autoimmune diseases, and allergies. Our initial focus will be on skin allografts and psoriasis, as we believe these indications will be most efficient in providing safety and efficacy data in clinical trials. To submit a Biologics License Application (“BLA”) for a biopharmaceutical product, clinical safety and efficacy must be demonstrated in a series of clinical studies conducted with human subjects. For products in our class of drugs, the first-in-human trials will be a combination of Phase I (safety/tolerability) and Phase II (efficacy) in affected subjects. To obtain approval to initiate the Phase I/IIa studies, an Investigational New Drug Application will be submitted to compile non-clinical efficacy data as well as manufacturing and pre-clinical safety/toxicology data. To date, we have conducted non-clinical studies in a stringent model of skin transplantation using genetically mismatched donor and recipient animals demonstrating a 3-fold increase in the survival of the skin graft in animals that were tolerized with ADi™ compared to animals that receive immune suppression alone. Prolongation of graft life was observed despite discontinuation of immune suppression after the first 5 weeks. Additionally, in an induced non-clinical model for psoriasis, ADi™ treatment resulted in a 69% reduction in skin thickness and a 38% decrease in skin flaking (two clinical parameters for assessment of psoriasis skin lesions). The Phase I/IIa studies in psoriasis will evaluate the safety/tolerability of ADi™ in patients diagnosed with psoriasis. Since the drug will be administered in subjects diagnosed with psoriasis, effectiveness of the drug to improve psoriatic lesions will also be evaluated. In another Phase I/IIa study, patients requiring skin allografts will receive weekly intra-dermal injections of ADi™ in combination with standard immune suppression to assess safety/tolerability and possibility of reducing levels of immunosuppressive drugs as well as prolongation of graft life. Later phase trials are planned after successful completion of these studies in preparation for submission for a BLA to regulatory agencies.
