IMUNON Announces 11.1 Month Increase in Overall Survival in Patients with Newly Diagnosed, Advanced Ovarian Cancer Treated with IMNN-001

On July 30, 2024 IMUNON, Inc. (NASDAQ: IMNN), a clinical-stage company in late-stage development with its DNA-mediated immunotherapy, reported positive topline results from the Phase 2 OVATION 2 Study with IMNN-001 in patients with advanced ovarian cancer (Press release, IMUNON, JUL 30, 2024, View Source [SID1234645156]). OVATION 2 is a randomized study of IMNN-001 in combination with neoadjuvant and adjuvant chemotherapy (NACT) inclusive of interval debulking or cytoreductive surgery compared with a control arm of standard-of-care NACT alone. IMNN-001 is the Company’s interleukin-12 (IL-12) immunotherapy based on its TheraPlas technology.

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 population (ITT).
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 intent-to-treat population of 0.79, indicating a 27% improvement in delaying progression for the IMNN-001 treatment arm.
"These strong and clinically meaningful Phase 2 results are highly encouraging, suggesting that IMNN-001 may improve the outcomes for women with advanced ovarian cancer. In the near term, we look forward to advancing our therapeutic into a Phase 3 pivotal study as soon as possible," said Stacy Lindborg, Ph.D., President and Chief Executive Officer of IMUNON. "Advancements in treatment options for advanced ovarian cancer in women who require neoadjuvant treatment have been limited over the years, and these patients continue to have poor prognoses. Our goal is for IMNN-001 to play an important role in the treatment regimen for the more than 300,000 women diagnosed with this deadly disease. On behalf of IMUNON, I extend heartfelt thanks to the women who participated in this trial, their families and the investigators."

OVATION 2 evaluated the dosing, safety, efficacy and biological activity of intraperitoneal administration of IMNN-001 in combination with NACT of paclitaxel and carboplatin in patients newly diagnosed with advanced epithelial ovarian, fallopian tube or primary peritoneal cancer. Treatment in the neoadjuvant period is designed to shrink the tumors as much as possible for optimal surgical removal after three cycles of chemotherapy. Following NACT, patients undergo interval debulking surgery, followed by three additional cycles of adjuvant chemotherapy to treat any residual tumor. This open-label study enrolled 112 patients who were randomized 1:1 and evaluated for safety and efficacy to compare NACT plus IMNN-001 versus standard-of-care NACT. In accordance with the study protocol, patients randomized to the IMNN-001 treatment arm could receive up to 17 weekly doses of 100 mg/m2 in addition to NACT.

As a Phase 2 study, OVATION 2 was not powered for statistical significance. Additional endpoints included objective response rate, chemotherapy response score and surgical response.

Sebastien Hazard, M.D., Chief Medical Officer of IMUNON, added, "It is highly gratifying to witness the extraordinary overall survival benefit that IMNN-001 showed in this Phase 2 study further supported by consistency across data, including in progression-free survival and in the patients who received three doses or more of IMNN-001 gaining an additional 15.7 months of life, while the safety profile was tolerable. It suggests that IMUNON’s IL-12 gene therapy has a long-term impact on the disease."

Commenting on the study results, Premal H. Thaker, M.D, Interim Chief of Gynecologic Oncology, David & Lynn Mutch Distinguished Professor of Obstetrics & Gynecology, Director of Gynecologic Oncology Clinical Research at Washington University School of Medicine, and the OVATION 2 Study Chair, said, "Typically an increase in survival of six months is considered to be clinically meaningful, and extending survival from 29 months with standard-of-care treatment to 40 months with the addition of IMNN-001 is compelling. Importantly, the extension of survival among IMNN-001 patients also exposed to the new standard that includes PARP inhibitors is even greater. If confirmed in a Phase 3 clinical trial, IMNN-001 could reset the standard of care for women with ovarian cancer."

Charles A. "Trey" Leath, III, M.D., Director, Division of Gynecologic Oncology, Ellen Gregg Shook Culverhouse Chair in Gynecologic Oncology, Professor, Department of Obstetrics and Gynecology at University of Alabama Medical Center, and OVATION 2 Principal Investigator, said, "I (We) have been investigating IMNN-001 since the Phase 1 OVATION 1 Study and continue to be frustrated by the lack of substantial progress in primary treatment options available to treat this disease. The results from this trial demonstrating that IMNN-001 could extend life by one year or longer are provocative and powerful. I believe that should efficacy be confirmed in a pivotal study, IMNN-001 will be quickly incorporated into the care regimen."

IMUNON plans to hold an End-of-Phase 2 meeting with the U.S. Food and Drug Administration as soon as possible to discuss the protocol for a Phase 3 study, which is anticipated to begin in the first quarter of 2025. IMUNON 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.

About IMNN-001 Immunotherapy

Designed using IMUNON’s proprietary TheraPlas platform technology, IMNN-001 is an IL-12 DNA plasmid vector encased in a nanoparticle delivery system that enables cell transfection followed by persistent, local secretion of the IL-12 protein. IL-12 is one of the most active cytokines for the induction of potent anticancer immunity acting through the induction of T-lymphocyte and natural killer cell proliferation. IMUNON previously reported positive safety and encouraging Phase 1 results with IMNN-001 administered as monotherapy or as combination therapy in patients with advanced peritoneally metastasized primary or recurrent ovarian cancer, and completed a Phase 1b dose-escalation trial (the OVATION 1 Study) of IMNN-001 in combination with carboplatin and paclitaxel in patients with newly diagnosed ovarian cancer.

About Epithelial Ovarian Cancer

Epithelial ovarian cancer is the sixth deadliest malignancy among women in the U.S. There are approximately 20,000 new cases of ovarian cancer every year and approximately 70% are diagnosed in advanced Stage III/IV. Epithelial ovarian cancer is characterized by dissemination of tumor in the peritoneal cavity with a high risk of recurrence (75%, Stage III/IV) after surgery and chemotherapy. Since the five-year survival rates of patients with Stage III/IV disease at diagnosis are poor (41% and 20%, respectively), there remains a need for a therapy that not only reduces the recurrence rate, but also improves overall survival. The peritoneal cavity of advanced ovarian cancer patients contains the primary tumor environment and is an attractive target for a regional approach to immune modulation.

FibroGen Announces Topline Results from Two Late-Stage Pamrevlumab Pancreatic Cancer Studies and Provides Corporate Update

On July 30, 2024 FibroGen, Inc. (NASDAQ: FGEN) reported topline results from two late-stage trials evaluating the efficacy and safety of pamrevlumab in patients with pancreatic cancer and a corporate update (Press release, FibroGen, JUL 30, 2024, View Source [SID1234645155]).

The pamrevlumab experimental arm in PanCAN’s Precision Promise Phase 2/3 adaptive platform trial compared treatment with pamrevlumab combined with gemcitabine + nab-paclitaxel to gemcitabine + nab-paclitaxel alone for treatment in first line (1L) and second line (2L) patients with metastatic pancreatic ductal adenocarcinoma (mPDAC). The pamrevlumab arm of the study did not meet the primary endpoint of overall survival as determined by the protocol pre-specified Bayesian statistical analysis.

The Phase 3 LAPIS trial compared treatment with pamrevlumab combined with gemcitabine + nab-paclitaxel or FOLFIRINOX to placebo combined with gemcitabine + nab-paclitaxel or FOLFIRINOX for the treatment of locally advanced, unresectable pancreatic cancer (LAPC). The study did not meet the primary endpoint of overall survival.

"We are deeply disappointed that the pamrevlumab arm in the Precision Promise trial and the LAPIS trial did not meet the primary endpoint of overall survival," said Thane Wettig, Chief Executive Officer, FibroGen. "We were hopeful that pamrevlumab could bring meaningful innovation to pancreatic cancer patients in desperate need of new therapies. FibroGen would like to thank the patients, their families and the clinical trial investigators and teams for their dedication to participating in these studies. I would also like to express my deepest gratitude to our FibroGen colleagues who have dedicated so much of their time and energy for the prospect of bringing much needed therapies to some of the most challenging and deadly diseases affecting humanity."

Based upon the results of the late-stage pamrevlumab trials in pancreatic cancer, the Company plans to implement an immediate and significant cost reduction plan in the U.S. The pamrevlumab development program will be terminated and the Company plans to expeditiously wind down any remaining pamrevlumab obligations. As a result of the cost reduction plan, headcount in the U.S. will be reduced by approximately 75%.

FibroGen’s collaboration agreement with AstraZeneca for roxadustat in China, where roxadustat is the market leader by brand value share in the chronic kidney disease (CKD) anemia category, as well as FibroGen’s collaboration agreement with Astellas for roxadustat in the E.U., Japan, and other territories, remain in place.

PanCAN’s Precision Promise Pamrevlumab Arm Efficacy Results

Given both 1L and 2L pamrevlumab treatment groups graduated into Stage 2 of PanCAN’s Precision Promise study, the hazard ratio for the primary overall survival (OS) analysis assumed a common hazard ratio to estimate a single treatment effect for both 1L and 2L pamrevlumab patients combined compared to patients treated with gemcitabine + nab-paclitaxel. In addition, the pre-specified Bayesian model utilized a hierarchical model that included the borrowing of data from the mFOLFIRINOX control arm to the gemcitabine + nab-paclitaxel control arm for the primary efficacy analysis. The pre-specified primary efficacy analysis was performed in a modified intention-to-treat (mITT) population that included only subjects who initiated treatment. The mITT population in the pamrevlumab arm was comprised of a total of 102 patients in the 1L treatment group and 111 patients in the 2L treatment group and the gemcitabine + nab-paclitaxel control arm was comprised of a total of 34 patients in the 1L treatment group and 36 patients in the 2L treatment group.

Primary OS Analysis as Determined by Pre-Specified Bayesian Statistical Analysis (mITT Population)

Bayesian Model Common Hazard Ratio (HR) Posterior Probability
Median Mean (SD) 95% CI Pr(HR < 1)
Primary Efficacy Analysis 1.170 1.184 (0.175) (0.882, 1.563) 0.13977
LAPIS Efficacy Results

The study did not meet the primary endpoint of overall survival (stratified log-rank p-value=0.55). Median overall survival of 17.3 months was observed in the pamrevlumab combined with gemcitabine + nab-paclitaxel or FOLFIRINOX arm compared to median overall survival of 17.9 months in the control arm of placebo combined with gemcitabine + nab-paclitaxel or FOLFIRINOX (HR: 1.08; 95% CI – 0.83 to 1.41).

Pamrevlumab Safety Results (Precision Promise and LAPIS)

The preliminary safety analyses across both studies indicate that the safety profile of pamrevlumab combined with gemcitabine + nab-paclitaxel or FOLFIRINOX was generally well tolerated with an acceptable safety profile in pancreatic cancer patients. No clinically meaningful differences in treatment emergent adverse events were seen between the treatment arms.

About PanCAN’s Precision Promise
PanCAN’s Precision Promise adaptive platform trial (NCT04229004) is a U.S.-based, seamless Phase 2/3 study sponsored by PanCAN that enrolled patients in 24 sites nationwide. The multi-arm study consists of experimental treatment arms and two comparator arms: gemcitabine + nab-paclitaxel and mFOLFIRINOX. The pamrevlumab experimental arm enrolled 102 patients with mPDAC in first line (1L) and 111 patients with mPDAC in second line (2L). Both 1L and 2L patients received pamrevlumab in combination with gemcitabine and nab-paclitaxel. The final analysis was based upon the data collected up to 12 months after the last patient initiated treatment.

About LAPIS
The LAPIS study is a global Phase 3, randomized, double-blind trial to evaluate the efficacy and safety of neoadjuvant treatment with pamrevlumab or placebo in combination with either gemcitabine + nab-paclitaxel or FOLFIRINOX in the treatment of participants with locally advanced, unresectable pancreatic cancer (LAPC). The study enrolled 284 patients, who were randomized at a 1:1 ratio to receive either pamrevlumab or placebo, in combination with either gemcitabine + nab-paclitaxel or FOLFIRINOX. All patients were dosed up to six cycles of treatment and patients who completed study treatment were evaluated for surgical exploration for possible R0 or R1 resection. Participants who were ineligible for surgical exploration continued to receive treatment as per standard of care (SOC) for each institution.

About Pamrevlumab
Pamrevlumab is a potential first-in-class anti-CTGF fully human monoclonal antibody being developed by FibroGen to inhibit the activity of connective tissue growth factor (CTGF). Pamrevlumab is in clinical development for the treatment of metastatic pancreatic cancer and locally advanced unresectable pancreatic cancer (LAPC). The U.S. Food and Drug Administration has granted Orphan Drug Designation for the treatment of patients with pancreatic ductal adenocarcinoma (PDAC), and Fast Track designation to pamrevlumab for the treatment of patients with LAPC. Pamrevlumab is an investigational drug and not approved for marketing by any regulatory authority. For information about our pamrevlumab studies please visit www.clinicaltrials.gov.

CNS Pharmaceuticals Expands Pipeline with In-License of Late Stage, Novel Potential Blood Brain Barrier Permeable Abeotaxane for Treatment of Brain Malignancies

On July 30, 2024 CNS Pharmaceuticals, Inc. (NASDAQ: CNSP) ("CNS" or the "Company"), a biopharmaceutical company specializing in the development of novel treatments for primary and metastatic cancers in the brain and central nervous system, reported that it has entered into an exclusive license agreement with Cortice Biosciences, Inc. ("Cortice") (Press release, CNS Pharmaceuticals, JUL 30, 2024, View Source [SID1234645151]). The Company will host a live webcast presentation to discuss the transaction on Tuesday, July 30, 2024 at 8:30 AM ET (details below). Additionally, CNS announced the launch of its new corporate branding and website, cnspharma.com.

Under the terms of the Agreement, CNS Pharmaceuticals has obtained an exclusive license and the intellectual property rights to TPI 287, a potentially blood brain barrier permeable microtubule inhibitor, currently in development for the treatment of GBM, in exchange for an upfront payment of 616,698 shares of the Company’s common stock, as well as the possibility of future success-dependent milestone payments of cash or the Company’s common stock to Cortice. CNS Pharmaceuticals intends to advance the development of TPI 287 for an oncology indication in the United States, Canada, Mexico, and Japan, which is the territory covered by the Agreement (the "Territory"). Such development efforts will include, but may not be limited to, the prosecution and maintenance of existing and new intellectual property; preclinical and clinical development of TPI 287 including research, manufacturing, laboratory and clinical testing, regulatory filing, and marketing of TPI 287 in the Territory.

John Climaco, CEO of CNS Pharmaceuticals, stated, "For years, our team has searched for another drug candidate with the same high level of human data-supported therapeutic potential in GBM as Berubicin. The in-licensing of TPI 287 is a transformational step forward and we are prepared for the next stage to execute our vision of CNS Pharmaceuticals being the leading biopharma company developing drugs for this devastating and currently inescapably fatal disease."

"Our vision is anchored by our confidence in and commitment to our trial of Berubicin in patients with recurrent GBM. The 252 patients enrolled in its potentially pivotal trial will provide significant data about overall survival compared with Lomustine, the outcome of which will be made public in the first half of next year. Our highly experienced team that created and is executing this trial – currently one of the largest GBM studies being conducted anywhere in the world – makes us uniquely positioned to meet the challenge presented by this disease. The clinical network we have established is unparalleled by any other company’s GBM development program, and as a consequence, the TPI 287 program will require only limited capital resources prior to the release of Berubicin topline data. This will allow us to drive TPI 287 into potential registration studies in the most cost-effective manner possible. After negotiations spanning several years and following extensive scientific and clinical due diligence, we believe the highly compelling safety and efficacy data demonstrated by TPI 287 in over 350 patients to date makes it both the ideal complementary asset to Berubicin and the perfect next step in our Company’s strategic plan. Our work on bringing TPI 287 to patients begins immediately," added Mr. Climaco.

TPI 287 Key Highlights

· TPI 287 is an abeotaxane and has the same mechanism of action as other taxanes, e.g. paclitaxel (Taxol) and docetaxel, in which it stabilizes microtubules and inhibits cell division, causing apoptosis and cell death. While most taxanes are substrates for multi-drug resistant transporters, which maintain the blood brain barrier (BBB), similarly to Berubicin, TPI 287 has shown the potential to cross the BBB and treat CNS tumors.

· TPI 287 has been well tolerated in over 350 patients to date, including in clinical trials as a monotherapy and in combination with bevacizumab for the treatment of recurrent neuroblastoma and medulloblastoma, as well as refractory prostate cancer and melanoma, and in tauopathy disease, which can result in dementia.

· In a multicenter Phase 1 study evaluating TPI 287 in combination with bevacizumab in patients with recurrent GBM, results demonstrated an objective response rate of 60% and disease control rate of 96% in 23 subjects. Progression-free survival (PFS) of 5.5 months and overall survival (OS) of 13.4 months compare favorably to bevacizumab either as monotherapy or in combination with chemotherapy in similar patients yielding PFS of 2-4 months and OS of 6-9 months. The data from this study were recently published in a manuscript titled, "Phase 1 trial of TPI 287, a microtubule stabilizing agent, in combination with bevacizumab in adults with recurrent glioblastoma1," in Neuro-Oncology Advances.

· CNS Pharmaceuticals plans to engage the U.S. FDA and obtain feedback on the design of a study focused on the registration of TPI 287 in recurrent GBM, with the goal of initiating the study in 2025.

Samuel A. Goldlust, MD, Medical Director of Neuro-Oncology at Saint Luke’s Cancer Institute, a former investigator in the Company’s global study of Berubicin, as well as the principal investigator of studies of TPI 287 in GBM added, "The data seen to date with TPI 287 have been highly encouraging. There remains a tremendous unmet need for the GBM patient population, which I believe will require the development of a variety of effective therapeutic approaches. With the promising data demonstrated with both Berubicin and the synergies that TPI 287 has shown, I am excited for the Company to further explore and unlock the potential of TPI 287."

As previously announced in April 2024, the Company completed enrollment in its global potentially pivotal study evaluating Berubicin for the treatment of GBM. In December 2023 the Company announced the successful completion of its pre-planned interim futility analysis and received a recommendation from the independent Data Safety Monitoring Board (DSMB) to continue the study without modification. CNS Pharmaceuticals expects to report topline results from its potentially pivotal study of Berubicin in the first half of 2025.

"We also fully understand that the complexity and severity of GBM challenges scientists and clinicians to create novel treatment approaches for brain malignancies. As we have grown our expertise in the development of blood brain barrier permeable chemotherapeutics, we understand that multiple therapeutics may be required to effectively treat these diseases. Combinations of anthracyclines and taxanes that have shown activity for systemic disease may be more powerful as combination agents for the treatment of diseases metastatic to the brain. There is tremendous potential therapeutic synergy between Berubicin and TPI 287, and we are excited to expand our pipeline of drug candidates to offer patients with recurrent GBM an additional brain-penetrative chemotherapeutic option," added, Sandra Silberman, MD, PhD, Chief Medical Officer of CNS. "Having successfully completed enrollment in our Berubicin study, we have gained extensive experience and expertise in conducting late-stage registrational studies for recurrent GBM. That experience will now inform our clinical strategy for TPI 287 as we engage with key investigators at our active clinical sites. Our investigator network, which took years to build, can now be repurposed to save valuable time and resources, allowing us to expeditiously move forward with a similar potentially registrational study of TPI 287 in 2025."
