"The second quarter and recent weeks were exciting and highly rewarding," said Stacy Lindborg, Ph.D., president and chief executive officer of IMUNON. "Positive topline results from our Phase 2 OVATION 2 Study with IMNN-001 in advanced ovarian cancer were the culmination of years of dedication by the IMUNON team and set our company’s strategic plan going forward. We reported overall survival among patients treated with IMNN-001 of more than 11 months compared with patients treated with standard-of-care, and believe these results provide hope to women suffering from a disease with such a poor prognosis. Our next steps include holding an End-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) to clarify our path to a Phase 3 pivotal study."

Dr. Lindborg added, "The addition of approximately $9.3 million in net proceeds from a capital raise last month in a challenging market, along with the steps we have taken to conserve capital allows the Company to report many important catalysts, including the initiation of a planned Phase 3 study of IMNN-001."

RECENT DEVELOPMENTS

IMNN-001 Immunotherapy

Reported Positive Topline Results From OVATION 2 Study in Advanced Ovarian Cancer – On June 24, 2024, the Company announced database lock for the OVATION 2 Study. At that time, median overall survival (OS) and progression-free survival (PFS) had been reached, and all patients in the open-label study had achieved treatment observation duration of 16 months, as required per protocol to evaluate efficacy. On July 30, 2024, the Company announced positive topline results from the Phase 2 OVATION 2 Study. Highlights from patients treated with IMNN-001 plus standard-of-care in a first-line treatment setting include:

An 11.1 month increase in median OS compared with standard-of-care alone in the intent-to-treat (ITT) population.
A hazard ratio in the ITT population of 0.74, which indicates a 35% improvement in survival.
Among the approximately 90% of trial participants who received at least 20% of specified treatments per-protocol in both study arms, patients in the IMNN-001 arm had a 15.7 month increase in median OS, representing a further extension of life with a hazard ratio of 0.64, a 56% improvement in survival.
For the nearly 40% of trial participants treated with a poly ADP-ribose polymerase (PARP) inhibitor, the hazard ratio decreased further to 0.41, with median OS in the IMNN-001 treatment arm not yet reached at the time of database lock, compared with median OS of 37.1 months in the standard-of-care treatment arm.
The PFS results, the trial’s primary endpoint, support the OS results with:

A three-month improvement in PFS compared with standard-of-care alone.
A hazard ratio in the ITT population of 0.79, indicating a 27% improvement in delaying progression for the IMNN-001 treatment arm.
The Company plans to hold an End-of-Phase 2 meeting with the FDA to discuss the protocol for a Phase 3 study, which is anticipated to begin in the first quarter of 2025. The Company also plans to present full OVATION 2 Study results at an upcoming medical conference and to submit the results for publication in a peer-reviewed medical journal.

MRD Study Advancing: Phase 1/2 Study of IMNN-001 in Combination with Bevacizumab, titled "Targeting Ovarian Cancer Minimal Residual Disease (MRD) Using Immune and DNA Repair Directed Therapies" – In February 2023, the Company and Break Through Cancer, a public foundation dedicated to supporting translational research in the most difficult-to-treat cancers that partners with top cancer research centers, announced the commencement of patient enrollment in a collaboration to evaluate IMNN-001 in combination with bevacizumab in patients with advanced ovarian cancer in the frontline, neoadjuvant clinical setting. MD Anderson Cancer Center, Dana-Farber Cancer Institute, The Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins and Memorial Sloan Kettering Cancer Center will be participating in the trial. In addition, The Koch Institute for Integrative Cancer Research at the Massachusetts Institute of Technology (MIT) will provide artificial intelligence services including biomarker and genomic analysis.

The study is expected to enroll 50 patients with Stage III/IV advanced ovarian cancer and is being led by principal investigator Amir Jazaeri, M.D., Vice Chair for Clinical Research and Director of the Gynecologic Cancer Immunotherapy Program in the Department of Gynecologic Oncology and Reproductive Medicine at MD Anderson. Patients are being randomized 1:1 in a two-arm trial. The trial’s primary endpoint is detection of minimal residual disease (MRD) by second look laparoscopy (SLL), with secondary endpoints including overall survival (OS) and progression-free survival (PFS). SLL data are expected within one year following the completion of enrollment and final data are expected approximately three years following the completion of enrollment.

As of June 30, 2024, seven patients were enrolled and had received treatment in the Phase 1 portion of this study at the University of Texas MD Anderson Cancer Center. Memorial Sloan Kettering Cancer Center was added as a clinical site for this study in the first quarter of 2024.

PlaCCine: Next Generation Prophylactic Vaccine Proof of Concept

First Participants Vaccinated in IMUNON’s IMNN-101 Phase 1 Clinical Trial – On April 18, 2024, the Company announced that it received clearance from the FDA to begin a Phase 1 clinical trial with a seasonal COVID-19 booster vaccine. The primary objectives of this proof-of-concept study of the PlaCCine DNA Vaccine technology platform are to evaluate safety, tolerability, neutralizing antibody response and the vaccine’s durability in healthy adults. Secondary objectives include evaluating the ability of the IMNN-101 vaccine to elicit binding antibodies and cellular responses and their associated durability. As currently planned, the Phase 1 study will enroll 24 subjects evaluating three escalating doses of IMNN-101. For this study, IMMN-101 has been designed to protect against the SARS-CoV-2 Omicron XBB1.5 variant. Assuming positive results, IMUNON will advance discussions with potential partners to continue development of the platform.

During the second quarter of 2024, the Company announced that DM Clinical Research in Philadelphia was the first clinical site activated and ready for patient recruitment for this Phase 1 study. DM Clinical Research is an integrated national network of clinical trial sites focused on delivering advanced, preventive medicine to underserved communities. Topline data are anticipated by year-end 2024.

Corporate Developments

Received Gross Proceeds of $10 Million in Registered Direct Financing – On July 30, 2024, the Company entered into a Securities Purchase Agreement with certain institutional and accredited investors, pursuant to which the Company agreed to issue and sell in a registered direct offering an aggregate of 5,000,000 shares of the Company’s common stock at an offering price of $2.00 per share for gross proceeds of $10.0 million. In a concurrent private placement (together with the registered direct offering) and also pursuant to the Securities Purchase Agreement, the Company agreed to issue to the Purchasers unregistered warrants to purchase shares of common stock. The warrants have an exercise price of $2.00 per share and will be exercisable immediately for a term of five and one-half years following the date of issuance.

About Alpha DaRT

Alpha DaRT (Diffusing Alpha-emitters Radiation Therapy) is designed to enable highly potent and conformal alpha-irradiation of solid tumors by intratumoral delivery of radium-224 impregnated sources. When the radium decays, its short-lived daughters are released from the sources and disperse while emitting high-energy alpha particles with the goal of destroying the tumor. Since the alpha-emitting atoms diffuse only a short distance, Alpha DaRT aims to mainly affect the tumor, and to spare the healthy tissue around it.

"Throughout the first half of the year, we focused on strengthening our balance sheet and advancing the development of inhaled LTI-03 in IPF," said Brian Windsor, Ph.D., President and Chief Executive Officer of Aileron. "We are extremely pleased with the positive data from Cohort 1 of the ongoing Phase 1b clinical trial announced in May, particularly the achievement of statistical significance in three out of eight biomarkers which is a testament to the potential of LTI-03 to inhibit fibrosis and improve lung function. Additionally, in May, we raised approximately $18.2 million in net proceeds in an underwritten registered direct offering, which provides us with the resources to further validate LTI-03 in the ongoing Phase 1b trial. We look forward to reporting topline results from the high-dose cohort in the third quarter of this year."

Second Quarter 2024 Highlights and Recent Updates

Corporate Updates

In May 2024, the Company completed an underwritten registered direct offering of 4,273,505 shares of its common stock and accompanying warrants to purchase an aggregate of 4,273,505 shares of its common stock. Net proceeds from the offering were approximately $18.2 million, after deducting underwriting discounts and commissions and other offering expenses. The Company has the potential to receive approximately $20.0 million in additional proceeds from the exercise of the warrants issued in the offering.
Pipeline

Announced positive Cohort 1 data from the ongoing Phase 1b clinical trial evaluating the safety and tolerability of inhaled LTI-03 in patients diagnosed with IPF.

Following inhaled administration of low dose LTI-03 (2.5 mg BID, or twice daily) in twelve patients, a positive trend was observed in seven out of eight biomarkers. The findings included:
Evidence of LTI-03 reducing expression of multiple profibrotic proteins produced in both basal-like cells and fibroblasts that contribute to the progression of IPF, with statistically significant decreases in three biomarkers, reinforcing the potential of LTI-03 to inhibit fibrosis, inflammation and associated changes in the lungs.
LTI-03 stimulated production of solRAGE, a factor indicative of type I epithelial cell health, a critically important aspect of IPF that has gone largely unaddressed.
LTI-03 was generally well-tolerated with no serious adverse events ("SAEs") reported.
The Phase 1b trial is ongoing, with topline results from the high-dose Cohort 2 expected in the third quarter of 2024.

On May 1, 2024, the Company hosted a pulmonary care expert call to discuss the Cohort 1 Phase 1b results of LTI-03, featuring pulmonary care expert Andreas Günther, M.D., Head of the Center for Interstitial and Rare Lung Diseases at the Justus Liebig University in Giessen, Germany. A replay of the event can be accessed at View Source

LTI-01 is in development for loculated pleural effusion ("LPE"), a serious consequence of pneumonia with significant unmet medical need.
Second Quarter 2024 Financial Results

Cash Position: Cash and cash equivalents as of June 30, 2024, were $21.9 million, compared to $12.0 million as of March 31, 2024.

Patients in the Company’s lung cancer clinical trials are being treated with the Company’s lead drug candidate, Reqorsa (quaratusugene ozeplasmid) Gene Therapy. Two patients in the Acclaim-1 study have had prolonged Progression Free Survival (PFS) and importantly, the first treated patient in the Acclaim-3 study attained a Partial Remission (PR) from the start of maintenance therapy.

Ryan Confer, President and Chief Executive Officer of Genprex, commented on the update:

"We are excited by these early and promising patient responses to REQORSA treatment, particularly as these patients represent some of the most difficult to treat lung cancer patient populations. There is significant unmet medical need for patients afflicted with lung cancer, as nearly all patients’ disease progresses following treatment, even when treated with today’s most advanced targeted therapies and immunotherapies. This leaves patients with limited therapeutic options. We are thrilled our novel gene therapy treatment for lung cancer, REQORSA, is demonstrating early evidence of efficacy with a favorable safety profile. We look forward to continuing to evaluate REQORSA in our lung cancer clinical trials while we advance our efforts to bring new therapies to those battling cancer."

Acclaim-1

The Acclaim-1 clinical trial is evaluating the combination of REQORSA and AstraZeneca’s Tagrisso to treat patients with late-stage NSCLC who have activating EGFR mutations and disease progression after treatment with Tagrisso. The Acclaim-1 clinical trial has received an U.S. Food and Drug Administration (FDA) Fast Track Designation for late-stage NSCLC patients whose disease progressed after treatment with Tagrisso.

Two patients from the Phase 1 dose escalation portion of the study have had prolonged PFS and are still continuing to receive treatment on the study. One of them has received the treatment combination of REQORSA and Tagrisso for more than two years. This patient, who was previously treated with Tagrisso and chemotherapy and who continues to receive REQORSA and Tagrisso treatment, attained a PR after the second course of REQORSA and Tagrisso, and has maintained this response for more than two years. The second patient has had stable disease without disease progression for more than 15 months, and is also continuing to receive REQORSA and Tagrisso treatment.

Mark Berger, MD, Chief Medical Officer of Genprex, discussed the positive outcomes:

"We are very pleased with the positive early efficacy results for these patients. It is very compelling that one of the patients in our Acclaim-1 clinical trial has continued to see benefit from REQORSA treatment for more than two years and it’s been documented that the side effects of REQORSA have diminished, rather than increased, over time."

The Phase 2a expansion portion of the study was designed to have two cohorts with 33 patients each. One cohort was for patients who have previously received only Tagrisso treatment, and one cohort was for patients who had previously received both Tagrisso treatment and chemotherapy. Based on resource prioritization and to focus on the patients for whom REQORSA is most likely to show a benefit, the Company has decided to limit its enrollment efforts moving forward to patients who received only prior Tagrisso treatment and to cease enrollment of the second cohort (patients who received prior Tagrisso treatment and chemotherapy). The Phase 2a expansion portion of the trial with one cohort is now expected to enroll approximately 33 patients. The Phase 2b randomized portion of the study, in which patients progressing on prior Tagrisso treatment will be randomized 1:1 to either REQORSA and Tagrisso combination therapy or to platinum-based chemotherapy, will remain unchanged.

Genprex will conduct an interim analysis following the treatment of 19 patients in the Phase 2a expansion portion who had previously received only Tagrisso treatment. The Company expects to complete the enrollment of the first 19 patients in the Phase 2a expansion portion of the study and conduct an interim analysis in the first half of 2025.

Acclaim-3

The Acclaim-3 clinical trial is evaluating the combination of REQORSA and Genentech’s Tecentriq as a maintenance therapy to treat patients with extensive stage small cell lung cancer (ES-SCLC) who did not develop tumor progression after receiving Tecentriq and chemotherapy as initial standard treatment. The FDA has granted Fast Track Designationfor the Acclaim-3 population of patients and has also granted Orphan Drug Designation for the treatment of SCLC.

In this study, patients receive maintenance therapy with REQORSA and Tecentriq until disease progression or unacceptable toxicity is experienced. Following completion of the Phase 1 dose escalation portion of the study, which the Company expects to complete during the second half of 2024, Genprex then expects to start the Phase 2 expansion portion of the study in the second half of 2024.

The first patient treated in the Phase 1 dose escalation portion of the Acclaim-3 clinical trial experienced an initial positive response after enrollment and dosing commenced in May. The patient had a PR, which is defined as at least a thirty percent (30%) decrease in tumor size, from the time the patient had a baseline CT scan after induction therapy and prior to the start of maintenance therapy, to the time of the CT scan performed after two cycles of maintenance therapy. As the maintenance therapy consists of REQORSA and Tecentriq, and the patient had already received four cycles of Tecentriq during induction therapy and thus responses to Tecentriq would likely have occurred earlier, which suggests that REQORSA may be providing clinical benefit. A recent CT scan, performed after four cycles of maintenance therapy (three months), confirms that the patient had a 30% decrease in tumor size in measurable lesions; however one lesion not previously measurable had grown in size, thus leading to a conclusion of disease progression at three months.

Dr. Berger commented on these compelling results:

"This patient’s response was not expected during maintenance therapy with Tecentriq alone, and we believe these results are promising and a positive early indication for the study. Once ES-SCLC patients begin maintenance therapy with Tecentriq, median PFS is very short; only 2.6 months, and further tumor regression rarely occurs. The ES-SCLC patient in the Acclaim-3 clinical trial treated with our combination therapy experienced PR, but asymptomatic disease progression was diagnosed by CT scan three months after the start of maintenance therapy. We find this positive result to be promising, particularly because this patient was treated with the lower of two doses planned for the Phase 1 portion of this clinical trial, and we are hopeful that the combination of REQORSA and Tecentriq will improve outcomes and help extend the lives of these very difficult to treat lung cancer patients."

Genprex’s novel cancer treatment platform re-expresses tumor suppressor genes in cancers. Tumor suppressor genes are often deleted or inactivated early in the process of cancer development. The key component of REQORSA is a plasmid that expresses TUSC2, a tumor suppressor gene protein which plays a vital role in cancer suppression and normal cell metabolism. Nearly 100% of SCLCs have reduced or no TUSC2 protein expression, and 41% completely lack TUSC2 protein expression, thus restoring TUSC2 expression in SCLC has a strong biologic rationale. Nonclinical studies in mice support the hypothesis that re-expressing the TUSC2 protein in combination with Tecentriq may lead to improved clinical efficacy in SCLC.

Oncology Program Update

Mr. Confer and the executive team have evaluated resource allocations to ensure streamlined, focused strategies to support expeditious regulatory submissions for REQORSA and will implement the following changes to the Company’s oncology clinical development plans in order to prioritize resources and focus on the most promising aspects of the Acclaim-1 and Acclaim-3 lung cancer clinical trials.

The Acclaim-2 clinical trial, a Phase 1/2 trial evaluating the combination of REQORSA and Merck & Co’s Keytruda in patients with late-stage NSCLC whose disease has progressed after treatment with Keytruda, will cease enrollment of new NSCLC patients. Current patients in the Phase 1 dose escalation portion of the study will continue to be treated until disease progression. The Company made this decision based on a number of factors, including enrollment challenges and delays due to competition for eligible patients with numerous other trials involving the same patient population.
As described above, the Company will limit its enrollment efforts for the Phase 2a expansion portion of the Acclaim-1 study moving forward to patients who received only prior Tagrisso treatment and cease enrollment of the second cohort (patients who received prior Tagrisso treatment and chemotherapy). The Phase 2a expansion portion of the trial with one cohort is now expected to enroll approximately 33 patients. The Company continues to evaluate ways to optimize its clinical and research programs and operational strategies, as part of its ongoing prioritization initiative.
Commenting on the decision, Mr. Confer stated:

"The decision to discontinue the Acclaim-2 clinical trial is driven in part by the fact that there are hundreds of Keytruda combination lung cancer clinical trials, which made it difficult to recruit patients and investigators due to the volume of competing trials. We thank the clinicians and patients who participated in this study and look forward to potentially reviewing this patient population again at a future time, as we fully stand behind REQORSA’s potential to treat late-stage NSCLC patients whose disease progressed after treatment with Keytruda."

Additionally, Genprex reports that the Company is collaborating with an academic research partner to discover, develop and utilize biomarkers to:

select the patient population most likely to respond to REQORSA;
predict and measure target engagement; and
enable decisions on progression of the Company’s drug candidates to the next phase of development.
The Company’s academic research partner is currently analyzing biomarkers that would indicate lack of response in lung cancer that could enrich the Company’s population of responders in its clinical trials and enhance patient screening and enrollment in order to increase the likelihood of potential success of the Acclaim studies.
