"Current gold standard CSF cytology lacks the sensitivity needed to reliably diagnose LM in most clinical situations and lacks utility for disease monitoring," said Marc H. Hedrick, M.D., Plus Therapeutics’ President and Chief Executive Officer. "The FORESEE trial shows that CNSide may be a useful tool in accurately identifying all patients with LM, ruling out patients at risk, and enhancing the disease management and monitoring of LM."

Key highlights:

The FORESEE trial achieved its primary endpoint, demonstrating that CNSide influenced treatment decisions in over 90% of cases evaluated, surpassing the predetermined 20% primary endpoint target
CNSide demonstrated enhanced sensitivity in detecting tumor cells (80%) vs. CSF cytology (29%) in patients with LM
CNSide identified actionable mutations in the CSF, such as HER2 amplification, influencing 24% of therapeutic selection decisions
CNSide exhibited high specificity, with no tumor cells detected in patients without LM
CNSide demonstrated improved Negative Predictive Value in ruling out LM (25%) vs. CSF cytology (10%)
CNSide revealed HER2 positivity in LM tumors in 60% of breast cancer patients with HER2-negative primary tumors, informing physician treatment strategies
The data will be presented on Sunday, November 24, at 10:15 a.m. CST in a session titled, "CSF Tumor Cell (CSF-TC) Detection, Quantification and Biomarker assessment Helps in Clinical Management of Breast Cancer and Non-Small Cell Lung Cancer Patients Having Leptomeningeal Disease (FORESEE Study, NCT-5414123)," by Priya Kumthekar, M.D., Associate Professor of Neurology and Hematology/Oncology, and Director of Brain Metastases Program at Northwestern, University, Chicago, Illinois.

About CNSide Test
The CNSide Cerebrospinal Fluid (CSF) Assay Platform consists of four laboratory developed tests (LDTs) used for diagnosis, treatment selection, and treatment monitoring of patients with Leptomeningeal Metastases (LM) from carcinomas or melanoma. The CNSide platform facilitates tumor cell detection / enumeration and biomarker identification using cellular assays (immunocytochemistry (ICC) and fluorescence in situ hybridization (FISH)) and molecular assays (next generation sequencing (NGS)). The CNSide CSF tumor cell enumeration LDT is currently being used in the ReSPECT-LM trial as an exploratory endpoint, and is anticipated to become commercially available in 2025.

About Leptomeningeal Metastases (LM)

LM is a rare complication of cancer in which the primary cancer spreads to the cerebrospinal fluid (CSF) and leptomeninges surrounding the brain and spinal cord. All malignancies originating from solid tumors, primary brain tumors, or hematological malignancies have this LM complication potential with breast cancer as the most common cancer linked to LM, with 3-5% of breast cancer patients developing LM. Additionally, lung cancer, GI cancers and melanoma can also spread to the CSF and result in LM. LM occurs in approximately 5% of people with cancer and is usually terminal with 1-year and 2-year survival of just 7% and 3%, respectively. The incidence of LM is on the rise, partly because cancer patients are living longer and partly because many standard chemotherapies cannot reach sufficient concentrations in the spinal fluid to kill the tumor cells; yet, there are no FDA-approved therapies specifically for LM patients, who often succumb to this complication within weeks to several months, if untreated.

About FORESEE Clinical Trial

The FORESEE Study is a multi-center, prospective clinical trial enrolled patients with Breast or Non-Small Cell Lung Cancer (NSCLC) who have suspicious or confirmed Leptomeningeal Metastases (LM). Standard of Care methods to diagnose or assess the treatment response of LM (Clinical Evaluation, MRI and Cytology) have limited sensitivity and specificity. This creates challenges for physicians to manage LM or determine the best course of treatment. The goal of the FORESEE Study was to evaluate the performance of CNSide in monitoring the LM’s response to treatment and to assess the impact of CNSide on treatment decisions made by physicians.

Dr. Charles Cai, Chief Medical Officer of Leads Biolabs, said "LBL-024 obtained Breakthrough Therapy Designation from CDE in October this year for the treatment of advanced extrapulmonary neuroendocrine cancer. Our clinical data to date has been very encouraging, suggesting that LBL-024 could meaningfully improve outcomes of patients living with this devastating disease. The grant of ODD from FDA further underscores the exceptional potential of LBL-024 to address a critical gap in this therapeutic area. These policy supports for obtaining Orphan Drug qualification will greatly expedite the commercialization of LBL-024, potentially changing the treatment landscape for patients with advanced neuroendocrine cancer who currently have few therapeutic options."

Dr. Xiaoqiang Kang, founder, chairman and CEO of Leads Biolabs, said "The receipt of ODD for LBL-024 from FDA represents a pivotal milestone in our global strategy. This designation not only enables LBL-024 to receive additional policy support and resource allocation during its development, accelerating its path to market and positioning it as a potential first-in-class therapeutic antibody targeting 4-1BB worldwide, but also provides us with greater market opportunities and avenues for growth on a global scale."

About LBL-024

LBL-024 is a tetravalent bispecific antibody that simultaneously targets PD-L1 and 4-1BB, serving dual functions: blocking the immunosuppressive PD-1/PD-L1 pathway, and selectively co-stimulating 4-1BB in the tumor microenvironment to enhance immune responses. The dual functions of LBL-024—lifting PD-1/PD-L1 immune inhibition and intensifying 4-1BB modulated T cell activation—synergistically enhance the anti-tumor immune response.

LBL-024 received IND approvals from both FDA and NMPA on July 30, 2021 and September 9, 2021 respectively to conduct phase Ⅰ/Ⅱ clinical research, and has achieved outstanding results. Sponsored by Leads Biolabs, led by Professor Shen Lin from Beijing Cancer Hospital with participation of multiple clinical trial centers, the current clinical data demonstrate that LBL-024 monotherapy has more than doubled both the Objective Response Rate (ORR) and Overall Survival (OS) compared to existing treatments for this disease. Based on the current treatment status and the available safety and efficacy data, LBL-024 has entered into a single-arm pivotal trial for extrapulmonary neuroendocrine carcinomas in July 2024 and stands as the globally first 4-1BB-targetd drug candidates to have reached pivotal stage, according to Frost & Sullivan.

About Neuroendocrine Cancer

Neuroendocrine carcinoma (NEC) is a class of poorly differentiated, high-grade neuroendocrine neoplasms (NEN), which originate in the diffuse neuroendocrine cell system and may occur in many different sites. Its molecular characteristics are significantly different from those of neuroendocrine tumors (NET). NEC can be divided into pulmonary NEC and extrapulmonary NEC, among which pulmonary NEC includes small cell lung cancer (SCLC) and pulmonary large cell neuroendocrine carcinoma (p-LCNEC). According to previous data collected, the number of new cases of SCLC is about 98,193, p-LCNEC is about 19,639, and extrapulmonary NECs is about 9,820 in the United States every year. As a result, there are an estimated 127,652 new cases of NECs in the United States each year, meeting the FDA’s definition of a rare disease.

Symptoms of NEC can vary depending on the type of tumor, its location in the body and the hormone released. The survival rate of NEC varies according to the type of cancer and whether it spreads. Specifically, the 5-year survival rate of pulmonary NECs is 5.6%, digestive tract NECs is 13.1%, and other primary NECs are 26.0%. Due to the limited effective treatment options available for patients, the overall survival rate of NEC is low, and more effective new treatment options are urgently needed.

About Orphan Drug Designation

Orphan drugs are medications used for the prevention, treatment, and diagnosis of rare diseases. According to the Orphan Drug Act of the United States, Orphan Drug Designation is established to encourage the development of drugs for treating rare diseases. It provides a series of incentives for new drug development, including but not limited to: (1) tax credits for clinical trial expenses; (2) specific guidance from FDA on all stages of clinical research; (3) exemption of the application fee for new drug registration; and (4) 7 years of market exclusivity after listing.

On November 21, 2024 InxMed Co., Ltd, a clinical-stage biotechnology company developing innovative therapies against cancer treatment resistance and metastasis, reported that China National Medical Products Administration (NMPA) has granted Ifebemtinib (IN10018) Breakthrough Therapy designation (BTD) for the first-line (1L) treatment of non-small cell lung cancer (NSCLC) with KRAS G12C mutation in combination with garsorasib, a specific inhibitor of the KRAS G12C mutation (Press release, InxMed, NOV 21, 2024, View Source [SID1234648558]). This is the second BTD ifebemtinib received. In April 2022, ifebemtinib was granted its first BTD for the treatment of platinum-resistant ovarian cancer (PROC) in combination with PEG-liposomal doxorubicin (PLD).

Ifebemtinib is a highly selective, orally administered, small molecule inhibitor for focal adhesion kinase, which has demonstrated significant clinical synergies with targeted therapies, immunotherapies, and standard chemotherapies.

The BTD is supported by the data from the Phase Ib/II study evaluating the efficacy and safety of ifebemtinib in combination with garsorasib for the 1L treatment of NSCLC with KRAS G12C mutation (NCT06166836). The results of the clinical trial were featured at the 2024 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting. The dual-oral regimen showed promising antitumor efficacy with a well-tolerated safety profile in 1L KRASG12C NSCLC. The objective response rate (ORR) was 90.3% and the disease control rate (DCR) was 96.8%. A total of 28 confirmed partial responses (PRs) and two stable diseases (SDs) were reported from 31 efficacy evaluable patients. All treated patients have achieved a follow-up visit of 9 months so far, and the median PFS has not been reached at the time of this report.

Beyond KRAS G12C inhibitors, Ifebemtinib has also shown significant therapeutic synergies when combined with a wide range of standard and emerging cancer treatments, such as anti-PD-(L)1 antibodies, other RAS-targeted inhibitors, EGFR inhibitors, and ADCs. InxMed is actively pursuing collaborations with innovating partners globally。

InxMed is currently conducting a registrational trial in platinum-resistant ovarian cancer in China, for which the company plans to submit a New Drug Application to the NMPA in 2025. InxMed also has multiple proof-of-concept trials ongoing in lung, colorectal, melanoma, and pancreatic cancers, some of which will progress into pivotal studies. Thus far, more than 600 subjects have been treated with ifebemtinib, and a favorable safety and tolerability profile has been observed.
