ORGANIZATION AND NATURE OF BUSINESS	NOTE 1 – ORGANIZATION AND NATURE OF BUSINESS *Company Background* Overview We are a biotech innovation company with a mission of prolonging life and enhancing its quality by improving the health of the immune system. We are an innovation company developing and commercializing technologies with a focus on monitoring and modulating the immune system. Our immune reprogramming technologies are currently at the pre-clinical stage and are designed to retrain the immune system to induce tolerance with an objective of addressing rejection of transplanted organs, autoimmune diseases, and allergies. Our immune monitoring technologies are designed to provide a personalized comprehensive profile of the immune system and we plan to utilize them in our upcoming reprogramming clinical trials to monitor subjects’ immune response before, during and after drug administration. On January 1, 2023, the Company formed Adimune, Inc., a Delaware wholly owned subsidiary. On January 1, 2023, the Company formed Pearsanta, Inc., a Delaware wholly owned subsidiary. On April 13, 2023, the Company formed Adivir, Inc., a Delaware wholly owned subsidiary.

There was no change to the number of authorized shares of the Company’s common stock. All share amounts referenced in this report are adjusted to reflect the 2023 Reverse Split. Offerings On August 31, 2021, the Company completed a registered direct offering (“August 2021 Offering”). In connection therewith, the Company issued 2,292 shares of common stock, at a purchase price of $4,800.00 per share, resulting in gross proceeds of approximately $11.0 million. In a concurrent private placement, the Company issued warrants to purchase up to 2,292 shares. The warrants have an exercise price of $5,060.00 per share and are exercisable for a five-year period commencing months from the date of issuance. The warrants exercise price was subsequently repriced to $3,000.00. In addition, the Company issued a warrant to the placement agent to purchase up to 115 shares of common stock at an exercise price of $6,000.00 per share. On October 18, 2021, the Company entered into an underwriting agreement with Revere Securities LLC, relating to the public offering (the “October 2021 Offering”) of 1,417 shares of the Company’s common stock (the “Shares”) by the Company.

On December 6, 2021, the Company completed a public offering for net proceeds of $16.0 million (the “December 2021 Offering”). As part of the December 2021 Offering, we issued 4,123 units consisting of shares of the Company’s common stock and warrant to purchase shares of the Company’s common stock and 4,164 prefunded warrants.

On April 20, 2023, the Company entered into a securities purchase agreement (the “April Purchase Agreement”) with an institutional investor, pursuant to which the Company agreed to sell to such investor pre-funded warrants (the “April Pre-Funded Warrants”) to purchase up to 39,634 shares of common stock of the Company (the “Common Stock”) at a purchase price of $48.76 per April Pre-Funded Warrant. The April Pre-Funded Warrants (and shares of common stock underlying the April Pre-Funded Warrants) were offered by the Company pursuant to its shelf registration statement on Form S-3 (File No. 333-257645), which was declared effective by the Securities and Exchange Commission on July 13, 2021. Concurrently with the sale of the April Pre-Funded Warrants, pursuant to the Purchase Agreement in a concurrent private placement, for each April Pre-Funded Warrant purchased by the investor, such investor received from the Company an unregistered warrant (the “Warrant”) to purchase two shares of Common Stock.

In addition, the Company issued a warrant to the placement agent to purchase up to 2,378 shares of common stock at an exercise price of $61.00 per share. The closing of the sales of these securities under the April Purchase Agreement took place on April 24, 2023.

The Company’s business and operations are sensitive to general business and economic conditions in the U.S. and worldwide along with local, state, and federal governmental policy decisions. A host of factors beyond the Company’s control could cause fluctuations in these conditions. Adverse conditions may include: changes in the biotechnology regulatory environment, technological advances that render our technologies obsolete, availability of resources for clinical trials, acceptance of technologies into the medical community, and competition from larger, more well-funded companies. These adverse conditions could affect the Company’s financial condition and the results of its operations. On January 30, 2020, the World Health Organization declared the COVID-19 novel coronavirus outbreak a “Public Health Emergency of International Concern” and on March 10, 2020, declared it to be a pandemic. Actions taken around the world to help mitigate the spread of the coronavirus included restrictions on travel, and quarantines in certain areas, and forced closures for certain types of public places and businesses. The COVID-19 coronavirus and actions taken to mitigate it have had an adverse impact on the economies and financial markets of many countries, including the geographical area in which the Company operates. While it is unknown how long these conditions will last and what the financial impact will be to the Company, it is reasonably possible that future capital raising efforts and additional development of our technologies may be negatively affected.
