Business Activities and Organization

 

We are a clinical-stage biopharmaceutical company focused on utilizing the Processa Regulatory Science Approach including the principles associated with FDA’s Project Optimus Oncology initiative and the related FDA Draft Guidance, in the development of NGC oncology drug products. Our mission is to provide better treatment options than those that presently exist by extending a patient’s survival and/or improving a patient’s quality of life. This is achieved by taking FDA-approved, widely used oncology drugs or the cancer killing metabolites of these drugs and altering how they are metabolized and/or distributed in the body, including how they are distributed to the actual cancer cells. By changing either the metabolism, distribution and/or elimination of already FDA-approved cancer drugs while maintaining the mechanism of how the drug kills cancer cells, we believe our three Next Generation Chemotherapy (NGC) treatments will provide improved safety-efficacy profiles when compared to their currently marketed counterparts - capecitabine, gemcitabine, and irinotecan. All future studies of these drugs are subject to availability of capital to conduct the trials.

 

The three NGC treatments in our pipeline are as follows:

 

NGC-Capecitabine is a combination of PCS6422 and capecitabine. NGC-Capecitabine alters the metabolism of capecitabine without having any clinically meaningful biological effect itself. In clinical trials, NGC-Capecitabine has a safety profile different than capecitabine when administered by itself. Side effects, such as Hand-Foot Syndrome (HFS) and cardiotoxicity that typically occur in 50-70% of patients treated with capecitabine and caused by specific capecitabine metabolites that are not formed to any extent with NGC-Capecitabine, do not appear to be side effects associated with NGC-Capecitabine. These types of toxicities can result in decreased doses, interrupted doses, or discontinuation of treatment with capecitabine. In addition, NGC-Capecitabine has been found to be greater than 50 times more potent than capecitabine based on the systemic exposure of the capecitabine metabolite 5-FU, which is metabolized to the cancer-killing metabolites. Like capecitabine, NGC-Capecitabine could be used to treat patients with various cancers, such as metastatic colorectal, gastrointestinal, breast and pancreatic. We estimate at least 200,000 patients in the United States were diagnosed in 2022 with metastatic colorectal, gastrointestinal, breast, and pancreatic cancers. In mid-April of 2023, we are scheduled to begin discussions with the FDA regarding the design of our Phase 2B trial and Project Optimus in order to initiate the Phase 2B trial in the second half of 2023.
     
NGC-Gemcitabine (also identified as PCS3117) is an oral analog of gemcitabine that is converted to its active metabolite by a different enzyme system than gemcitabine resulting in a positive response in gemcitabine patients as well as some gemcitabine treatment-resistant patients. Like gemcitabine, NGC-Gemcitabine could be used to treat patients with various cancers such as pancreatic, lung, ovarian, and breast. We estimate at least 275,000 patients in the United States were diagnosed in 2022 with pancreatic, lung, ovarian, and breast cancer. We plan to meet with the FDA in 2023 to discuss potential study designs including implementation of Project Optimus initiative as part of the design, and then submit the Phase 2B protocol to the Investigational New Drug (IND Application) in the second half of 2023.
     
NGC-Irinotecan (also identified as PCS11T) is a prodrug of the active metabolite of irinotecan (SN-38). The chemical structure of NGC-Irinotecan influences the uptake of the drug into cancer cells, resulting in more NGC-Irinotecan entering cancer cells than normal cells in mice. These levels were significantly greater than those seen with irinotecan, resulting in lower doses of NGC-Irinotecan having greater efficacy than irinotecan and improved safety in animal models. Like irinotecan, NGC-Irinotecan could be used to treat patients with various cancers such as lung, colorectal, gastrointestinal, and pancreatic cancer. We estimate at least 200,000 patients in the United States were diagnosed in 2022 with lung, colorectal, gastrointestinal, and pancreatic cancer. We plan to conduct IND-enabling and toxicology studies in 2023 and 2024.

 

Historically, much of oncology drug development has searched for a new or different way to treat cancer. Our approach is to modify and improve three different, currently approved, and widely used chemotherapy treatments so that the human body handles these NGC treatments differently than their presently approved counterpart drugs while the cancer killing mechanism of action remains the same. FDA’s Project Optimus Oncology initiative and Oncology Guidance recommends that the dose-response (both safety and efficacy) relationships be evaluated for all oncology drugs. We have begun this process for our NGC treatments. To date, we have found that our NGC treatments are likely to have a better safety-efficacy profile than the current widely used marketed counterpart drugs, not only potentially making the development and approval process more efficient, but also differentiating our NGC treatments from the existing treatment. We believe our NGC treatments have the potential to extend the survival and/or quality of life for more patients diagnosed with cancer while decreasing the number of patients who are required to dose adjust or discontinue treatment because of side effects or lack of response.

 

As part of our shift in priority, including the allocation of resources to NGC drugs, we suspended further enrollment in the PCS499 trial for uNL. We are evaluating options to monetize both PCS12852 and PCS499. The clinical study findings for PCS12852 were positive in gastroparesis patients and there were no safety concerns noted during the conduct of either study.

 

 

Recent Financings

 

Registered Direct Offering

 

On February 9, 2023, we entered into a securities purchase agreement (the “Purchase Agreement”) relating to the issuance and sale of shares of common stock pursuant to a registered direct offering (the “Offering”) with certain accredited investors (the “Investors”). The Investors purchased approximately $6.3 million of shares, consisting of an aggregate of 7,812,544 shares of common stock at a purchase price of $0.80 per share. The Purchase Agreement provides that, subject to certain exceptions, until the earlier of (i) 90 days after the closing of the Offering or (ii) the trading day following the date that our common stock’s closing price exceeds $2.00 for a period of 10 consecutive trading days neither we nor our subsidiary will issue or enter into any agreement to issue or announce the issuance or proposed issuance of any shares of common stock or common stock equivalents.

 

The net proceeds from the Offering, after deducting the fees of the Placement Agent, Spartan Capital Securities, LLC (“Spartan”), and the estimated offering expenses, were approximately $5.7 million. The Offering closed on February 14, 2023.

 

The common stock was offered and sold pursuant to our Registration Statement on Form S-3 (Registration No. 333-257558) previously filed with the Securities and Exchange Commission and declared effective on July 9, 2021, the base prospectus included therein and the related prospectus supplement dated February 9, 2023.

 

We paid the Placement Agent a cash fee of 8.0% of the gross proceeds from the Offering, excluding proceeds received from our insiders, and reimbursed the Placement Agent for legal fees of $60,000. The engagement agreement with the Placement Agent requires us to indemnify the Placement Agent and certain of its affiliates against certain customary liabilities. We also amended our consulting agreement with Spartan, entered into on August 24, 2022, extending the term of the consulting agreement until February 10, 2024. We will compensate Spartan for financial consulting services provided under the amendment by granting Spartan warrants to purchase 3,160,130 shares of our common stock on April 17, 2023 with an exercise price of $1.02. The warrants will expire three years from the date of issuance and contain both call and cashless exercise provisions.

 

At-the-Market Transactions

 

On August 20, 2021, we entered into an equity distribution agreement (the “Sales Agreement”) with Oppenheimer & Co. Inc. (the “Sales Agent”) under which we may issue and sell in a registered “at-the-market” offering shares of our common stock having an aggregate offering price of up to $30.0 million from time to time through or to our Sales Agent (the “ATM Offering”). We expect to use net proceeds from the ATM Offering over time as a source for working capital and general corporate purposes. We are not obligated to make any sales of our common stock under the Sales Agreement and no assurance can be given that we will sell any shares under the Sales Agreement, or, if we do, as to the price or amount of shares that we will sell, or the dates on which any such sales will take place. We will pay the Sales Agent an aggregate of up to 3.0% of the gross proceeds of the sales price per share of common stock sold through the Sales Agent under the Sales Agreement. The shares under the ATM Offering will be sold and issued pursuant to our S-3 shelf registration statement (Registration No. 333-257588), declared effective on July 9, 2021.

 

On February 3, 2023, we sold 569,648 shares of our common stock under the ATM Offering resulting in net proceeds of $672,393. We did not sell any shares under our ATM Offering during the year ended December 31, 2022 and sold 21,597 shares of our common stock during the year ended December 31, 2021 for aggregate net proceeds of approximately $174,000. On February 5, 2023, we suspended the Sales Agreement and terminated the prospectus supplement.

 

Equity Line of Credit Transactions

 

On March 23, 2022, we entered into a purchase agreement (the “Purchase Agreement”) with Lincoln Park Capital Fund, LLC (“Lincoln Park”), pursuant to which Lincoln Park has committed to purchase up to $15.0 million of shares (the “Purchase Shares”) of our common stock, subject to the terms and conditions in the Purchase Agreement. We issued 123,609 shares of common stock (valued at $450,000) to Lincoln Park as a commitment fee in connection with entering into the Purchase Agreement and reimbursed Lincoln Park $25,000 for fees incurred in connection with the Purchase Agreement. Concurrently with entering into the Purchase Agreement, we also entered into a registration rights agreement with Lincoln Park (the “Registration Rights Agreement”), pursuant to which we agreed to take certain actions relating to the registration under the Securities Act of 1933, as amended, of the offer and sale of the shares of common stock available for issuance under the Purchase Agreement.

 

We did not draw on our Equity Line of Credit with Lincoln Park in 2022. In January 2023, we sold Lincoln Park 50,000 shares of our common stock for proceeds of $54,000.

 

Impairment of PCS499 In-process Research and Development Asset

 

In February 2023, we suspended further enrollment in our PCS499 trial for uNL due to difficulties we encountered in enrolling our PCS499 trial for uNL. As a result, we recognized a non-cash expense of $7.3 million at December 31, 2022 related to the impairment of the intangible asset for PCS499 (see Note 3). We originally recognized this intangible asset in conjunction with its acquisition from CoNCERT Pharmaceuticals, Inc. in 2018.
