We are a clinical stage biopharmaceutical company focused on developing therapies for the treatment of high impact, difficult to treat cancers through the inhibition of glycogen synthase kinase-3 (GSK-3). We are developing elraglusib (formerly 9-ING-41), an ATP-competitive small molecule that is designed to enter cancer cells and block the function of the enzyme glycogen synthase kinase-3 beta (“GSK-3β”), a master regulator of complex biological signaling cascades, including those mediated by oncogenes, that lead to tumor cell survival, growth, migration, and invasion. We believe that the blockade of GSK-3β signaling ultimately results in the death of the cancer cells and the regulation of anti-tumor immunity.

We have exclusively licensed a portfolio of GSK-3 inhibitors developed in a collaboration between The Board of Trustees of the University of Illinois-Chicago (“UIC”) and Northwestern University (“NU”). Elraglusib is the lead drug in our portfolio and is being evaluated in a randomized Phase 2 trial in patients with metastatic pancreatic ductal adenocarcinoma (“mPDAC”), our most advanced clinical indication to date. We are also advancing a Phase 1/2 clinical trial in refractory pediatric malignancies, including Ewing sarcoma (“EWS”).

(“LucidDx Labs”) and CapNostics, LLC (“CapNostics”). Background and Overview Lucid Diagnostics is a commercial-stage medical diagnostics technology company focused on the millions of patients with gastroesophageal reflux disease (“GERD”), also known as chronic heartburn, acid reflux or simply reflux, who are at risk of developing esophageal precancer and cancer, specifically highly lethal esophageal adenocarcinoma (“EAC”).

Our EsoGuard commercialization efforts span multiple channels including targeting primary care and GI physicians, who have generally embraced our message that EsoGuard has the potential to expand the funnel of BE-EAC patients who will need long term EGD surveillance and, potentially, treatment with endoscopic esophageal ablation. To assure sufficient testing capacity and geographic coverage, we have undertaken multiple ways for patients have access to our test. Initially, we built a limited network of our own physical Lucid Test Centers, staffed by Lucid-employed clinical personnel, where patients can undergo the EsoCheck procedure and have the sample sent for EsoGuard testing at our CLIA-certified laboratory. Our current test center network currently includes locations in metropolitan areas in Arizona, California, Colorado, Florida, Georgia, Idaho, Michigan, Nevada, Texas and Utah.

EsoGuard and EsoCheck are based on patented technology licensed by Lucid from Case Western Reserve University (“CWRU”). EsoGuard and EsoCheck have been developed to provide accurate, non-invasive, patient-friendly testing for the early detection of EAC and Barrett’s Esophagus (“BE”), including dysplastic BE and related pre-cursors to EAC in patients with chronic GERD. Market Opportunity

EsoGuard is a bisulfite-converted targeted next-generation sequencing (NGS) DNA assay performed on surface esophageal cells collected with EsoCheck. It quantifies methylation at 31 sites on two genes, Vimentin (VIM) and Cyclin A1 (CCNA1). The assay has been evaluated in multiple studies, demonstrating sensitivity of ~90% for detecting disease along the full esophageal precancer to cancer spectrum, with a negative predictive value (NPV) of ~99%. Sensitivity and NPV remain very high even for detecting early precancer, which is unprecedented for a molecular diagnostic test.

Actuate Therapeutics, Inc. (the “Company”) was incorporated in the State of Delaware on January 16, 2015 and is headquartered in Fort Worth, Texas. The Company is a clinical-stage biopharmaceutical company focused on developing novel therapies for the treatment of cancers through the inhibition of glycogen synthase kinase-3 (“GSK-3”). The Company’s lead investigational product, elraglusib (formerly 9-ING-41), is a small molecule that is designed to enter cancer cells and block the function of the enzyme GSK-3β, thereby causing the death of the cancer cells and the regulation of anti-tumor immunity. The Company has a 100%-owned Irish subsidiary, Actuate Therapeutics Limited, that is currently dormant. Reverse Stock Split

Elraglusib may exert anticancer activity through a variety of mechanisms that may be context and cancer type specific. For example, GSK-3β mediates signaling of oncogenic PI-3K but if this oncogene is not expressed in a particular tumor, this would not be a pathway that could be targeted by elraglusib in that tumor. Potential antitumor activity through GSK-3β inhibition may occur through the following six mechanisms of action (see Figure 3 below): (1) Immune modulation; (2) Inhibiting cell proliferation; (3) Reducing tumor fibrosis; (4) Decreasing immune evasion; (5) Increasing apoptosis and disrupting DNA damage repair; and (6) Inhibition of epithelial-mesenchymal transitions (“EMT”). Figure 3: Elraglusib mechanisms of action. 8 (1) Immune modulation and inhibition of immune evasion

Elraglusib has now been demonstrated to decrease expression of PD-1, TIGIT and LAG-3 and to enhance the anti-tumor effects of anti-PD-1 checkpoint inhibition in animal tumor models. Thus, elraglusib blockade of GSK-3β activity may improve immune response to tumors by augmenting the responsiveness of a patient’s immune system in addition to the direct anti-tumor effects of elraglusib within the cancer cells themselves. (2) Inhibiting cell proliferation

EsoCheck is an FDA 510(k) and CE Mark cleared noninvasive swallowable balloon capsule catheter device capable of sampling surface esophageal cells in a less than five-minute office procedure. It consists of a vitamin pill-sized rigid plastic capsule tethered to a thin silicone catheter from which a soft silicone balloon with textured ridges emerges to gently swab surface esophageal cells. When vacuum suction is applied, the balloon and sampled cells are pulled into the capsule, protecting them from contamination and dilution by cells outside of the targeted region during device withdrawal. We believe this proprietary Collect+Protect™ technology makes EsoCheck the only noninvasive esophageal cell collection device capable of such anatomically targeted and protected sampling.

In June 2019, we received FDA 510(k) clearance to market EsoCheck in the U.S. as a device indicated for use in the collection and retrieval of surface cells of the esophagus in adults followed by FDA 510(k) clearance in 2022, expanding the use of EsoCheck in adults and pediatric populations in the U.S. In December 2019, our CLIA-certified then-laboratory partner, completed documentation of EsoGuard analytical validity allowing us to commercialize it as a LDT.
