On September 24, 2024 Silexion Therapeutics Corp. (NASDAQ: SLXN) ("Silexion" or the "Company"), a clinical-stage biotech developing RNA interference (RNAi) therapies for KRAS-driven cancers, reported significant new findings from its Phase 2 trial of LODER in patients with non-resectable locally advanced pancreatic cancer (LAPC) which bear the KRAS G12D or G12V mutation (approximately 70% of pancreatic cancer patients) (Press release, Silexion Therapeutics, SEP 24, 2024, View Source [SID1234646852]). Overall the updated analysis reveals a 56% objective response rate (ORR) in patients treated with LODER, with the ORR increasing to 67% in patients whose previously non-resectable tumors became resectable. This marks a significant step forward in potentially improving surgical outcomes for LAPC patients.

Silexion had previously reported that patients treated with LODER in combination with standard-of-care (SoC) chemotherapy experienced a 9.3-month improvement in overall survival (OS) compared to chemotherapy alone. The new data now underscores LODERs additional potential to increase the resectability of tumors, opening up more surgical options for patients with otherwise inoperable pancreatic cancer.

Silexion is also progressing with the development of its next generation product, SIL-204, which builds upon the efficacy of the LODER. SIL-204 is designed to target a broader range of KRAS mutations, covering pan- G12x and G13D, as well as the previously reported findings of properties which should make it more effective clinically such as improved stability and enhanced ability to get to the site of action for silencing the KRAS oncogene. These improved properties demonstrated in preclinical models position SIL-204 as a promising option for the treatment of difficult-to-treat cancers such as locally advanced pancreatic cancer. Silexion continues to proceed with the development of this optimized candidate.

"We are very encouraged by these new findings, which demonstrate LODER’s ability to significantly improve tumor resectability in patients with non-resectable pancreatic cancer, and the improved profile of SIL-204" said Ilan Hadar, Chairman and CEO of Silexion. "As we advance our broader pipeline to address KRAS-driven cancers, this data further validates our oncogene silencing approach."

About the Phase 2 Trial of LODER

The open-label Phase 2 trial enrolled 48 patients in the mITT population with non-resectable locally advanced pancreatic cancer (LAPC) and borderline resectable pancreatic cancer (BRPC) across the U.S. and Israel. The trial was conducted in two parts:

Cohort 1 (n=29): Patients were randomized 1:1 to receive either LODER with SoC chemotherapy or SoC chemotherapy alone. The primary endpoint was overall survival (OS), with 16 patients confirmed to harbor the KRAS G12D/V mutation.
Cohort 2 (n=19): This cohort enrolled patients with non-resectable tumors, LAPC or BRPC, with the key endpoints focused on ORR and safety. Seven patients in this cohort were confirmed to have KRAS G12D/V mutations.
Objective Response Rate for 23 patients confirmed with KRAS G12D/V (Cohorts 1+2)

Indication and Important Safety Information About POSLUMA

INDICATION

POSLUMA (flotufolastat F 18) injection is indicated for positron emission tomography (PET) of prostate-specific membrane antigen (PSMA) positive lesions in men with prostate cancer

with suspected metastasis who are candidates for initial definitive therapy
with suspected recurrence based on elevated serum prostate-specific antigen (PSA) level
IMPORTANT SAFETY INFORMATION

Image interpretation errors can occur with POSLUMA PET. A negative image does not rule out the presence of prostate cancer and a positive image does not confirm the presence of prostate cancer. The performance of POSLUMA for imaging metastatic pelvic lymph nodes in patients prior to initial definitive therapy seems to be affected by serum PSA levels and risk grouping. The performance of POSLUMA for imaging patients with biochemical evidence of recurrence of prostate cancer seems to be affected by serum PSA levels. Flotufolastat F 18 uptake is not specific for prostate cancer and may occur in other types of cancer, in non-malignant processes, and in normal tissues. Clinical correlation, which may include histopathological evaluation, is recommended.
Risk of Image Misinterpretation in Patients with Suspected Prostate Cancer Recurrence: The interpretation of POSLUMA PET may differ depending on imaging readers, particularly in the prostate/prostate bed region. Because of the associated risk of false positive interpretation, consider multidisciplinary consultation and histopathological confirmation when clinical decision-making hinges on flotufolastat F 18 uptake only in the prostate/prostate bed region or only on uptake interpreted as borderline.
POSLUMA use contributes to a patient’s overall long-term cumulative radiation exposure. Long-term cumulative radiation exposure is associated with an increased risk for cancer. Advise patients to hydrate before and after administration and to void frequently after administration. Ensure safe handling to minimize radiation exposure to the patient and health care providers.
The adverse reactions reported in ≥0.4% of patients in clinical studies were diarrhea, blood pressure increase and injection site pain.
Drug Interactions: androgen deprivation therapy (ADT) and other therapies targeting the androgen pathway, such as androgen receptor antagonists, may result in changes in uptake of flotufolastat F 18 in prostate cancer. The effect of these therapies on performance of POSLUMA PET has not been established.
To report suspected adverse reactions to POSLUMA, call 1-844-POSLUMA (1-844-767-5862) or contact FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

LMP744 treats gliomas, readily crossing the blood brain barrier (BBB) at 10 times the concentration required to kill cancer cells and sustains a high concentration for over 24 hours per dose.

"For decades glioblastoma brain cancer patients have not seen appreciable increases in overall survival rates with Temodar, the current standard of care treatment," said Mr. Randall Riggs, President & CEO of Gibson Oncology. "Our goal is to advance both LMP400 and LMP744 to market via the shortest and quickest path, thus benefiting cancer patients in need."

Obtaining ODD for LMP744 for all gliomas underscores the promising and novel treatment of the drug to inhibit two cancer targets: TOPO 1 and downregulate cMyc overexpression through the drug’s potent binding of the G4 quadruplex of cMyc.

"This crucial designation could not come at a more critical time for the families who are fighting this disease," said Dr. Kush Dhody, President, Amarex. "Reaching this milestone sets the company up for future success and, most importantly, poises Gibson Oncology to continue its path to commercialization of this life-saving treatment."

Through a multi-year collaboration with cMyc expert, Dr. Danzhou Yang of Purdue University, Gibson Oncology discovered that LMP400, which received ODD earlier in the year, and LMP744 are potent nM inhibitors of both TOPO 1 and cMyc oncogene. Together, the teams determined that LMP744, a small molecule, selectively targets two well-known drivers of human cancers, cMyc oncogene and TOPO 1.

The discovery of this compound’s unique anti-cancer mechanism of action (MOA) allowed Gibson Oncology to better position LMP744 and LMP400 to cancer targets with high unmet medical needs.

Presently, LMP744 and LMP400 is positioned to enter a Phase 2 human clinical trial in recurrent gliomas in collaboration with the National Institutes of Health (NIH).

Gibson Oncology believes it is important to leverage the Orphan Drug Designation both drugs have received from the FDA for all gliomas, not just glioblastomas, which includes children with gliomas. Rapid regulatory advancement empowers LMP400 and LMP744 to the shortest and quickest path to market, thus benefiting cancer patients in need.

On September 24, 2024 Anixa Biosciences, Inc. ("Anixa" or the "Company") (NASDAQ: ANIX), a biotechnology company focused on the treatment and prevention of cancer, reported its strategic plan for a Phase 2 study for its breast cancer vaccine (Press release, Anixa Biosciences, SEP 24, 2024, View Source [SID1234646849]). The Phase 1 trial is being conducted at Cleveland Clinic, funded by a grant from the U.S. Department of Defense.

The proposed Phase 2 trial will evaluate the efficacy of the vaccine administered in the neoadjuvant (before surgery) setting, in combination with chemotherapy and Keytruda (pembrolizumab). The goal of neoadjuvant therapy is to reduce tumor burden and to prevent tumor recurrence with the intent to improve survival. This clinical trial approach allows Anixa to enroll a broader range of patients, encompassing multiple types of breast cancer. The therapeutic market for breast cancer is large due to the increase in prevalence of breast cancer and an increase in screening resulting in a demand for treatment. Compared with primary prevention, the development path for breast cancer treatment is expected to have a shorter path to approval. The therapeutic market covers all stages of breast cancer, from early to advanced and metastatic cases. In 2023, the market was valued at approximately $38.35 billion and is projected to reach $89.67 billion by 2030, growing at a compound annual growth rate (CAGR) of 12.9% (Maximize Market Research).

The key objectives of the trial include evaluating the immunological response to the vaccine and comparing clinical efficacy of standard of care therapy alone with the vaccine plus standard of care therapy. A key component of this trial will be the evaluation of breast cancer tissue and the validation of the immunological mechanism of action of the vaccine.

The trial is expected to commence in 2025 and is projected to last approximately two to three years. Immunological responses to the vaccine will be made available as the trial advances, providing a faster and more cost-effective path toward potential approval and/or partnerships with pharmaceutical companies.

"We are excited to unveil our Phase 2 study plan, bringing us one step closer to a potentially transformative therapy for breast cancer patients," said Dr. Amit Kumar, Chairman and CEO of Anixa Biosciences. "By targeting treatment rather than prevention, we can reach a broader patient population and potentially expedite the process of regulatory approval and partnerships. This trial marks a key milestone in advancing our mission to fight cancer through innovative therapies. While our Phase 2 trial focuses on the therapeutic market, with the data obtained in this trial, we expect to conduct additional, more informed studies for both recurrence prevention and primary prevention with partners in the future."

Initial Phase 1 data was presented at the San Antonio Breast Cancer Symposium in December 2023. The data showed no safety concerns, with protocol defined immune responses observed in a majority of patients. Additional data from the Phase 1 trial will be presented at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) Annual Meeting in early November 2024.

The Phase 1 trial is conducted in collaboration with Cleveland Clinic and is funded by a grant from the U.S. Department of Defense. Anixa is the exclusive worldwide licensee of the novel breast cancer vaccine technology developed at Cleveland Clinic. The grant funding from the U.S. Department of Defense was provided to Cleveland Clinic.
