"We are pleased to be one step closer towards our goal of bringing mirdametinib to patients with NF1-PN in the U.S. and believe that our ReNeu data support the potential for mirdametinib to be a differentiated and best-in-class therapy for both children and adults living with this devastating disease," said Saqib Islam, Chief Executive Officer of SpringWorks. "We look forward to working closely with the FDA throughout the review process and also plan to file for regulatory approval in the European Union later this year."

The NDA submission includes data from the pivotal Phase 2b ReNeu trial, which evaluated mirdametinib in patients ≥ 2 years of age with NF1-associated PN causing significant morbidity. Results were presented in an oral presentation at the 2024 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting and demonstrated that mirdametinib treatment resulted in significant objective response rates confirmed by blinded independent central review, deep and durable responses, improvement in pain and health-related quality of life as well as a manageable safety profile across both the adult and pediatric cohorts.1

The FDA and the European Commission have granted Orphan Drug designation for mirdametinib for the treatment of NF1. The FDA has also granted Fast Track designation for the treatment of patients ≥ 2 years of age with NF1-PN that are progressing or causing significant morbidity and Rare Pediatric Disease designation for the treatment of NF1.

In the second half of 2024, SpringWorks also plans to file a Marketing Authorization Application (MAA) with the European Medicines Agency (EMA) for mirdametinib for the treatment of children and adults with NF1-PN.

About the ReNeu Trial

ReNeu (NCT03962543) is an ongoing, multi-center, open-label Phase 2b trial evaluating the efficacy, safety, and tolerability of mirdametinib in patients ≥ 2 years of age with an inoperable NF1-associated PN causing significant morbidity. The study enrolled 114 patients to receive mirdametinib at a dose of 2 mg/m2 twice daily (maximum dose of 4 mg twice daily) without regard to food. Mirdametinib was administered orally in a 3-week on, 1-week off dosing schedule as either a capsule or dispersible tablet. The primary endpoint is confirmed objective response rate defined as ≥ 20% reduction in target tumor volume during the 24 cycle treatment phase, as measured by MRI and assessed by blinded independent central review. Secondary endpoints include safety and tolerability, duration of response, and changes from baseline in patient reported outcomes to Cycle 13. The treatment phase of the trial is complete and results were presented at the 2024 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting. Patients who completed the treatment phase were eligible to continue receiving treatment in the optional long-term follow up portion of the study, which is ongoing.

About NF1-PN

Neurofibromatosis type 1 (NF1) is a rare genetic disorder that arises from mutations in the NF1 gene, which encodes for neurofibromin, a key suppressor of the MAPK pathway.2,3 NF1 is the most common form of neurofibromatosis, with an estimated global birth incidence of approximately 1 in 2,500 individuals, and approximately 100,000 patients living with NF1 in the United States.4,5 The clinical course of NF1 is heterogeneous and manifests in a variety of symptoms across numerous organ systems, including abnormal pigmentation, skeletal deformities, tumor growth and neurological complications, such as cognitive impairment.6 Patients with NF1 have an 8 to 15-year mean reduction in their life expectancy compared to the general population.3

NF1 patients have approximately a 30-50% lifetime risk of developing plexiform neurofibromas, or PN, which are tumors that grow in an infiltrative pattern along the peripheral nerve sheath and that can cause severe disfigurement, pain and functional impairment; in rare cases, NF1-PN may be fatal.7,8 NF1-PNs are most often diagnosed in the first two decades of life.7 These tumors can be aggressive and are associated with clinically significant morbidities; typically, they grow more rapidly during childhood.9,10

Surgical removal of these tumors is challenging due to the infiltrative tumor growth pattern along nerves and can lead to permanent nerve damage and disfigurement.11 MEK inhibitors have emerged as a validated class of treatment for NF1-PN.12

About Mirdametinib

Mirdametinib is a potent, oral, CNS-penetrant, allosteric small molecule MEK inhibitor in development as a monotherapy treatment for neurofibromatosis type 1-associated plexiform neurofibromas (NF1-PN) and low-grade glioma (LGG), and as a combination therapy for the treatment of several subsets of biomarker-defined metastatic solid tumors. Mirdametinib is an investigational drug for which safety and efficacy have not been established.

Mirdametinib is designed to inhibit MEK1 and MEK2, which occupy pivotal positions in the MAPK pathway. The MAPK pathway is a key signaling network that regulates cell growth and survival and plays a central role in multiple cancers and rare diseases when genetically altered.

The FDA and the European Commission have granted Orphan Drug designation for mirdametinib for the treatment of NF1. The FDA has also granted Fast Track designation for the treatment of patients ≥ 2 years of age with NF1-PN that are progressing or causing significant morbidity and Rare Pediatric Disease designation for the treatment of NF1.

On July 1, 2024 Innovent Biologics, Inc.

Gastric cancer is one of the most common malignant tumors in the world. According to the GLOBOCAN 2022 statistics[1], gastric cancer ranks as the 5th most common malignant tumor and the 5th leading cause of cancer death around the world. It accounts for an estimated 970,000 cases and 660,000 deaths worldwide. Each year, China reports 359,000 new cases and 260,000 deaths from gastric cancer, representing 37.0% and 39.4% of the global totals, respectively, highlighting a significant unmet medical need.

The data presented at this conference is from a Phase 1 study conducted in China and Australia with IBI343 and are as follows:

In participants with high expression of CLDN18.2 (≥75% tumor cells with membranous staining intensity ≥2+ by IHC) at the 6 mg/Kg dose (N=30), the ORR and DCR were 36.7% and 93.3%, respectively. At the 8 mg/kg dose (N=17), the ORR was 47.1% and the DCR was 88.2%.
With a median follow-up time of 7.2 months in the 6 mg/kg dose group, the median progression-free survival (mPFS) of participants with high CLDN18.2 expression was up to 6.8 months.
The majority of treatment emergent adverse events (TEAEs) were grade 1-2. In the 6 mg/kg dose group, 31.6% patients had ≥ Grade 3 treatment-related adverse events (TRAEs). ≥ Grade 3 gastrointestinal toxicities were extremely low (<5%). No interstitial lung disease (ILD) occurred.
Dr Jia (Jenny) Liu, translational lead of early phase clinical trials at The Kinghorn Cancer Centre, St Vincent’s Hospital Sydney, said: "As a next generation anti-CLDN18.2 antibody-drug conjugate that is Fc silenced, IBI343 has shown encouraging tolerability and clinical benefit in patients with advanced gastric and gastroesophageal junction adenocarcinomas that had moderate to high expression of CLDN18.2. Furthermore, the gastrointestinal toxicity of the drug we observed in the Phase 1 trial appears lower than that of other drugs targeting CLDN18.2, and there were no cases of interstitial lung disease. We look forward to seeing the results of ongoing Phase 3 trials comparing the efficacy and tolerability of IBI343 with standard-of-care treatments."

Dr. Hui Zhou, Senior Vice President of Innovent Biologics, said, "With a unique ADC platform designed to deliver effective and more tolerable therapeutics, the data in gastric cancer is a testimony to the molecular design of IBI343. We will further explore IBI343 in combination with other treatments, including immunotherapies, across different tumor types in order to benefit cancer patients worldwide. As a pioneer company in the field of oncology, Innovent is committed to advancing and promoting global innovation to develop and commercialize high quality biopharmaceuticals that are affordable to ordinary people."

Apart from gastric cancer, Innovent is also exploring IBI343’s therapeutic potential in solid tumors such as pancreatic cancer. Earlier this month, the data from the Phase 1 clinical study of IBI343 in the treatment of patients with pancreatic cancer were presented at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) 2024 Annual Meeting, demonstrating encouraging efficacy and a favorable safety profile.

About Gastric/ Gastroesophageal Junction Adenocarcinoma

Gastric cancer is one of the most prevalent malignant tumors worldwide and a leading cause of cancer-related deaths globally. The 5-year survival rate of patients with metastatic gastric cancer is less than 5%[2]. China and Japan have the highest incidence rates of gastric cancer[3]. Currently, the standard-of-care treatments for patients with advanced metastatic gastric cancer include a chemotherapy combination of fluoropyrimidine and platinum, as well as immune checkpoint inhibitor therapy. However, systemic therapy has limited efficacy in advanced gastric cancer. In particular, the prognosis for patients with third-line or higher gastric cancer is usually poor, with fewer treatment options and shorter survival expectations. The median survival times for these patients is only about 0.5 year[4].

Claudin, a member of the tight junction molecule family, is a key structural and functional component of epithelial tight junctions. Among them, CLDN18.2 is normally buried in the gastric mucosa, but the development of malignancy leads to disruption of tight junctions and exposure of CLDN18.2 epitopes on the membrane of tumor cells[5]. CLDN18.2 is expressed in up to 80% of patients with gastric cancer.

About IBI343（Anti CLDN18.2 ADC）

IBI343 is a recombinant human anti-CLDN18.2 monoclonal antibody-drug conjugate (ADC) developed by Innovent Biologics. IBI343 binds to the CLDN18.2-expressing tumor cells, the CLDN18.2 dependent ADC internalization will occur and the drug is released resulting in DNA damage and eventually apoptosis of the tumor cells. The freed drug can also diffuse across the plasma membrane to reach and kill the neighboring cells, resulting in "bystander killing effect".

As an innovative TOPO1i ADC, IBI343 has demonstrated tolerable safety and encouraging efficacy signals in this Phase 1 clinical studies. The therapeutic potential of IBI343 is currently being explored in tumor types such as gastric cancer and pancreatic cancer.

In May 2024, China’s National Medical Products Administration (NMPA) granted breakthrough therapy designation (BTD) to IBI343 for use as a single agent in patients with CLDN18.2–positive gastric or gastroesophageal junction (GEJ) adenocarcinoma who experienced disease progression following two prior lines of systemic treatment. The multi-center Phase 3 trial of IBI343 for this indication is in preparation. In June 2024, IBI343 received Fast Track Designation by the U.S. Food and Drug Administration (FDA) for the treatment of advanced unresectable or metastatic pancreatic ductal adenocarcinoma (PDAC) that has relapsed and/or is refractory to one prior line of therapy.

On July 01, 2024 Syncromune Inc., a clinical-stage biopharmaceutical company dedicated to developing innovative therapies for solid tumor cancers, reported that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation for SYNC-T SV-102 therapy, its lead candidate for the treatment of patients with metastatic castrate-resistant prostate cancer (mCRPC) (Press release, Syncromune, JUL 1, 2024, View Source [SID1234644626]). SV-102 is part of Syncromune Inc.’s innovative SYNC-T platform, an in situ personalized therapy that uniquely employs a combination multi-target approach to cancer treatment, aiming to improve outcomes and quality of life for patients.

The Fast Track designation was granted based on the potential of SYNC-T SV-102 therapy to address the significant unmet need in treating patients with mCRPC. This advanced form of prostate cancer affects over 40,000 men in the U.S. alone and is associated with a very poor prognosis. The Fast Track process is designed to facilitate the development and expedite the review of therapies that treat serious conditions and fulfill an unmet medical need, with the goal of getting important new treatments to patients sooner. Fast Track designation provides Syncromune with several key benefits, including more frequent FDA interactions, eligibility for accelerated approval, and priority review.

"The Fast-Track designation for SYNC-T SV-102 therapy signifies another step forward in bringing our potentially groundbreaking therapy to patients who need it most," said Eamonn Hobbs, Chief Executive Officer and co-founder of Syncromune. "This accomplishment builds upon the foundation of positive Phase 1 clinical data and recent IND clearance."

Syncromune’s lead candidate, SYNC-T SV-102, is a platform therapy that combines an in situ vaccine via partial oncolysis of a tumor followed by intratumoral infusion of the SV-102 fixed-dose multi-target biologic drug into the lysed tumor. This combination is designed to provide both immune stimulation and block immune suppression to activate and proliferate T cells to elicit a systemic anti-tumor response. Interim data from a Phase 1 study of SV-102 in males with mCRPC demonstrated an overall response rate of 85% with a favorable safety profile and tolerability. The Fast-Track designation comes on the heels of clearance of the company’s investigational new drug (IND) application, with studies expected to begin in the US this year.

Charles Link, M.D., Executive Chairman of Syncromune added, "We believe that Fast-Track designation for SYNC-T SV-102 will significantly aid our development goals for this therapy for men with difficult to treat prostate cancer. We look forward to initiating trials at multiple US sites later this year to expand our efforts to develop the SYNC-T SV-102 Therapy."

On July 1, 2024 Anbogen Therapeutics, Inc., a clinical-stage company dedicated to developing breakthrough cancer therapies, reported the successful closing of a USD 7.3M oversubscribed A+ round financing, which is a direct continuation of the USD 12.5 Million Series A on 1st February, 2024, bringing the total raised to USD 19.8M (Press release, Anbogen Therapeutics, JUL 1, 2024, View Source [SID1234644643]). The funds from the A+ round will be specifically used to advance the Phase II clinical trial of ABT-301. The financing round was led by KGI Venture Capital and both new and existing investors.

The capital raised in the A+ round will primarily be used to support the Phase II clinical trial of ABT-301 in combination with PD-1 inhibitors for treating microsatellite stable (MSS) metastatic colorectal cancer, which accounts for 95% of the metastatic colorectal cancer population that does not benefit from immune checkpoint inhibitors. Previous preclinical studies have repeatedly showed that ABT-301, when combined with immune checkpoint inhibitors, exhibits remarkable synergistic therapeutic effects in various solid tumor models, including subcutaneous xenograft and orthotopic models of colorectal cancer, liver cancer, triple-negative breast cancer, and head and neck cancer.

Given these promising results, Anbogen decided to proceed with the A+ round of financing to secure the necessary funds for ABT-301’s clinical trial, without impacting the ongoing Phase II development of ABT-101.

Leveraging ABT-301’s compelling immunomodulatory and synergistic effect combined with PD-1 treatment that Anbogen has observed, we have successfully engaged pharmaceutical companies who will agree to enter PD-1 drug-supply agreement with Anbogen. This collaboration will enable Anbogen to optimize its resource allocation and underscores the strong recognition of both ABT-301 and Anbogen.

"We are deeply grateful to our investors for their continued support and confidence in our mission," says Dr. Tsu-An Hsu, CEO of Anbogen Therapeutics. "This funding is crucial for the advancement of ABT-301 combo with immune checkpoint inhibitors treating solid tumors, and it validates our ongoing efforts to bring effective cancer treatments to patients in need."
