Strengths and Competitive Advantages

Large Market Opportunity for an Effective Solution

 

It is estimated that about 35 million people have AUD in the United States alone. Based on data from the Phase 2b trial of AD04 and our analysis of publicly available genetic databases, we preliminarily estimate that about one in three patients with AUD in the U.S. will have the genetic markers to indicate possible treatment with AD04. At this time, we are not aware of any oral pharmaceutical treatment approved in the U.S. that addresses the needs of patients who desire to control their drinking but cannot or do not want to abstain from drinking. The current abstinence-based treatments have limitations. The limited side effects expected for our investigational new drug, based on clinical data so far, are also believed to be an important factor in the expected market acceptance of AD04 . Our approach, if approved by FDA, may allow for social drinking to continue and is aimed at reducing dangerous, heavy drinking. This would allow patients to live the life they want without the stigma associated with complete abstention and currently endured by those seeking help for excessive drinking.

 

Prior work of Universities Creates Cost Efficiencies

 

We have a worldwide, exclusive license to intellectual property developed at the University of Virginia by a member of our board of directors, Dr. Bankole A. Johnson. Dr. Johnson was Chairman of the Department of Psychiatry & Neurobehavioral Sciences at the University of Virginia and is now Chair, Department of Psychiatry and Director of the Brain Science Research Consortium Unit at the University of Maryland, and has spent almost three decades researching the underlying subject matter.

 

By leveraging the prior work of universities and their researchers, including their pre-clinical studies and accumulated data, we believe we have developed a significant drug development opportunity. Because of the licensing approach taken to secure intellectual property, including, without limitation, patents and rights to clinical trial data, and our collaborations with the University of Virginia, we have not had to incur the significant costs that would normally be required to develop therapeutic treatments to the point of being ready to commence a Phase 3 clinical trial, which often amount to tens of millions of dollars or more. Based upon current information, and depending on what the regulatory authorities may require to secure marketing authorization, we estimate that we will only require approximately $6.5 million for the initial Phase 3 clinical trial (not including company overhead) and an additional $30 million of additional capital to complete our second Phase 3 program (which includes any necessary Phase 1 clinical trials) as currently contemplated in order to achieve regulatory approval for the use of AD04 to treat AUD in the United States and Europe.

 

Our Substantial Proprietary Estate and Protection from Competition

 

We currently hold a worldwide, exclusive license to three (3) patent families that provide us with the ability to exclude potential competitors from practicing the claimed inventions, such as the use of ondansetron to treat any of the four (4) specified genotypes for AUD. Our patent estate is expected to provide US patent protection through 2032 plus possible extensions. Ondansetron, the active ingredient in AD04, has never been approved in a low dosage near the AD04 dose of 0.33mg per tablet, and we believe our licensed patents will protect AD04 from any competitor that attempts to bring to market an ondansetron dose at or near the AD04 dose for treatment of patients having one of the four targeted genotypes.

We believe use of the currently marketed doses “off-label” will not be significant due to (i) the lack of demonstrated efficacy at currently marketed doses, (ii) potential safety concerns if the currently marketed doses are used chronically as is expected to be necessary for treating AUD, and (iii) cutting the smallest currently marketed dose into the 12 pieces that would be necessary to achieve the AD04 dose is deemed by us to be impractical and likely to result in inaccurate dosing.

 

Companion Genetic Bio-Marker Potentially Expands the Market Opportunity

 

We believe our drug is unique in that it is designed to treat individuals with certain genotypes. We are pursuing a strategy that aims to integrate pre-treatment screening with the companion diagnostic genetic test into the drug label, essentially combining the test and treatment into one integrated therapeutic offering that has combined intellectual property protections. This companion diagnostic testing approach may be a useful genetic screening tool to predict those most likely to respond to the drug and to have minimal side effects. Based on the clinical experience to date and publicly available databases, we believe the genetic prevalence of genotype positive people is about 33% of the population in the U.S. and that the prevalence in certain areas of Eastern Europe and in Scandinavia may be greater than 50%. The FDA has agreed that the Phase 3 trials of AD04 can proceed only enrolling patients that are genotype positive, which greatly reduces, the cost, time and risk relative to a trial that also enrolled patients that are genotype negative for treatment with AD04. Our plan to conduct our first Phase 3 trial in geographic areas with expected higher prevalence of genotype positive patients should further reduce the cost, time and risk to achieve Phase 3 results. The FDA has indicated that any approval based on a trial only in genotype positive patients would result in labeling restricted to treating genotype positive patients.
