Among the 33 patients evaluable as of November 8, 2022, the observed disease control rate was 87.9%, or 29 out of 33 patients as measured by RECISTv1.1, with two patients achieving partial responses (6.1%) and 27 patients achieving stable disease (81.8%). Disease control was observed in patients with and without IDH1/IDH2 mutations. Of those achieving stable disease 55.6% had decreases from baseline in tumor size. Clinical benefit was durable, 14 of 33 patients (42.4%) who achieved disease control had a clinical benefit lasting greater than 6 months, and the longest duration of stable disease is 20 months. To date, the median progression-free survival (PFS) is 7.6 months, and five patients remain on study.

Treatment-related adverse events (AEs) were reported in less than 5% of the patients with the most common being increased alanine aminotransferase (ALT), increased aspartate aminotransferase (AST), and increased blood bilirubin and fatigue. There were no grade 4 or 5 events reported among patients with treatment-related AEs.

About Chondrosarcoma
Chondrosarcoma is a rare malignant bone tumor of cartilage-producing cells and usually arises in the pelvis or long bones. Although chondrosarcoma is considered rare with an estimated annual incidence of 1 in 200,000, it is the most common primary bone cancer found in adults. Surgical resection is the only curative treatment and patients with unresectable or metastatic disease have a poor prognosis. There are currently no approved therapies for unresectable or metastatic chondrosarcoma.

About INBRX-109
INBRX-109 is a precision-engineered, tetravalent death receptor 5 (DR5) agonist antibody designed to exploit the tumor-biased cell death induced by DR5 activation.

In 2021, the FDA granted Fast Track designation to INBRX-109 for the treatment of patients with unresectable or metastatic conventional chondrosarcoma and orphan-drug designation to INBRX-109 for chondrosarcoma in the United States.

In June 2021, Inhibrx initiated a randomized, blinded, placebo-controlled, potential registration-enabling Phase 2 trial of INBRX-109 in conventional chondrosarcoma, which is currently ongoing.

On November 16, 2022 Astellas Pharma Inc. (TSE: 4503, President and CEO: Kenji Yasukawa, Ph.D., "Astellas") reported positive topline results from the Phase 3 SPOTLIGHT clinical trial evaluating the efficacy and safety of zolbetuximab in combination with mFOLFOX6 (a combination regimen that includes oxaliplatin, leucovorin and fluorouracil) (Press release, Astellas Pharma, NOV 16, 2022, View Source [SID1234624177]). Zolbetuximab is an investigational first-in-class monoclonal antibody targeting Claudin 18.2 (CLDN18.2), for the first-line treatment of patients with CLDN18.2-positive, HER2-negative, locally advanced unresectable or metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma.

The SPOTLIGHT trial enrolled 566 patients with CLDN18.2-positive, HER2-negative, locally advanced unresectable or metastatic gastric or GEJ adenocarcinoma. The study met its primary endpoint showing statistical significance in progression-free survival (PFS) for patients treated with zolbetuximab plus mFOLFOX6 compared to placebo plus mFOLFOX6. In addition, the study met a secondary endpoint, overall survival (OS), showing statistical significance for patients treated with zolbetuximab plus mFOLFOX6 compared to placebo plus mFOLFOX6. The most frequent treatment-emergent adverse events (TEAEs) in patients treated with zolbetuximab plus mFOLFOX6 were nausea, vomiting, and decreased appetite. Detailed results will be presented at a future scientific congress and submitted for publication.

"I am excited by the potential for a new treatment option to help patients with advanced-stage gastric cancer or GEJ cancer," said Kohei Shitara, MD, Primary Investigator for the SPOTLIGHT trial and Chief, Department of Gastrointestinal Oncology, the National Cancer Center Hospital East in Kashiwa, Japan. "Gastric and GEJ cancers still have very limited treatment options available for patients with an advanced diagnosis."

"We’re delighted and excited about the positive topline results from the SPOTLIGHT trial of zolbetuximab in combination with mFOLFOX6, and we have increased confidence in advancing development of zolbetuximab for the first-line treatment of patients with locally advanced or metastatic gastric cancer," said Ahsan Arozullah, M.D., M.P.H., Senior Vice President and Head of Development Therapeutic Areas, Astellas. "These topline results further support the role of CLDN18.2 as an emerging biomarker in gastric and GEJ cancer. We look forward to presenting the full results at a scientific congress in the near future."

Zolbetuximab acts by binding to CLDN18.2 on the cancer cell surface of gastric epithelial cells. In pre-clinical studies, this binding interaction then induces cancer cell death by activating two distinct immune system pathways — antibody-dependent cellular toxicity and complement-dependent cytotoxicity.1 CLDN18.2 is a type of transmembrane protein found in normal gastric cells and is a major component of epithelial and endothelial tight junctions controlling the flow of molecules between cells.2 Pre-clinical studies have shown that CLDN18.2, which can also be present in gastric tumors, may become more exposed and accessible to targeted therapies with antibodies as gastric tumors develop.3,4,5 Based on this study, approximately 38% of screened patients have CLDN18.2-positive tumors, defined as CLDN18.2 expression in ≥75% of tumor cells with strong-to-moderate staining intensity based on a validated immunohistochemistry assay.6

The Phase 3 SPOTLIGHT trial is a global, multi-center, double-blind, randomized study assessing the efficacy and safety of zolbetuximab plus mFOLFOX6 compared to placebo plus mFOLFOX6. Specifically, this study and the Phase 3 GLOW trial, which is evaluating the efficacy and safety of zolbetuximab plus capecitabine and oxaliplatin (CAPOX) compared to placebo plus CAPOX, are being conducted to provide foundational data for regulatory submissions in the U.S., Europe, Asia and other countries globally.

Gastric cancer is often diagnosed in the advanced or metastatic stage, or once it has spread from the tumor’s origin to other body tissues or organs.7 The five-year relative survival rate for patients at the metastatic stage is approximately six percent.8

About Zolbetuximab
Zolbetuximab is an investigational, first-in-class chimeric IgG1 monoclonal antibody (mAb) that targets and binds to CLDN18.2, a transmembrane protein. Zolbetuximab acts by binding to CLDN18.2 on the cancer cell surface of gastric epithelial cells. In pre-clinical studies, this binding interaction then induces cancer cell death by activating two distinct immune system pathways — antibody-dependent cellular cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC).1 The safety and efficacy of zolbetuximab are under investigation in gastric, gastroesophageal and pancreatic cancers and have not been established. There is no guarantee the agent will receive regulatory approval or become commercially available for the uses being investigated.

About SPOTLIGHT Phase 3 Clinical Trial
SPOTLIGHT is a Phase 3, global, multi-center, double-blind, randomized study, assessing the efficacy and safety of zolbetuximab (IMAB362) plus mFOLFOX6 (combination regimen of oxaliplatin, leucovorin and fluorouracil) compared to placebo plus mFOLFOX6 as a first-line treatment of patients with CLDN18.2-positive, HER2- negative, locally advanced unresectable or metastatic gastric or gastroesophageal junction cancer. The study enrolled 566 patients at 220 study locations in the U.S., United Kingdom, Australia, Europe, South America and Asia. The primary endpoint is progression-free survival of participants treated with combination of zolbetuximab plus mFOLFOX6 compared to those treated with placebo plus mFOLFOX6. Secondary endpoints include overall survival, objective response rate, duration of response, safety and tolerability and quality-of-life parameters.

About Locally Advanced Unresectable Metastatic Gastric and Gastroesophageal Junction Cancer
Gastric cancer, also commonly known as stomach cancer, is the fifth most commonly diagnosed cancer worldwide.9 Signs and symptoms can include indigestion or heartburn; pain or discomfort in the abdomen; nausea and vomiting; diarrhea or constipation; bloating of the stomach after meals; and loss of appetite and sensation of food getting stuck in the throat while eating.10 Signs of more advanced gastric cancer can include unexplained weight loss; weakness and fatigue; and vomiting blood or having blood in the stool.7 Risk factors associated with gastric cancer can include older age, male gender, family history, H. pylori infection, smoking and gastroesophageal reflux disease (GERD).7,11 Because early-stage gastric cancer symptoms frequently overlap with more common stomach-related conditions, gastric cancer is often diagnosed in the advanced or metastatic stage, or once it has spread from the tumor’s origin to other body tissues or organs.7 The five-year relative survival rate for patients at the metastatic stage is approximately six percent.8 Gastroesophageal junction (GEJ) adenocarcinoma is a cancer that starts at the area where the esophagus joins the stomach.12

On November 16, 2022 Ascletis Pharma Inc. (HKEX: 1672, "Ascletis") reported the approval of the Investigational New Drug (IND) application by China National Medical Products Administration (NMPA) for the in-house developed oral PD-L1 small molecule inhibitor, ASC61, for the treatment of advanced solid tumors. While the ASC61 Phase I dose escalation study is ongoing in the U.S., IND approval in China will accelerate the global development of ASC61 (Press release, Ascletis, NOV 16, 2022, View Source [SID1234624176]).

ASC61 is an oral small molecule inhibitor prodrug. Its active metabolite, ASC61-A, is a potent and highly selective inhibitor which blocks PD-1/PD-L1 interaction through inducing PD-L1 dimerization and internalization. As a single agent, ASC61 demonstrated significant antitumor efficacy in multiple animal models including humanized mouse model. Preclinical studies showed that ASC61 has good safety and pharmacokinetic profiles in animal models.

In a head-to-head comparison study using the human PD-L1 expressing cells and fresh peripheral blood mononuclear cells (PBMCs) co-culture assay, ASC61-A treatment induced secretion of IFNγ in a concentration dependent manner, with an EC50 of 2.86 nM. Maximal levels of IFNγ induced by ASC61-A were similar to that induced by Keytruda, a marketed PD-1 antibody.

Compared with PD-1/PD-L1 antibody injections, the oral PD-L1 inhibitor ASC61 has the following benefits: (1) higher patient compliance with easy and safe administration with no need of hospital visits for injections; (2) ease of all oral combination therapies with other oral anti-tumor drugs; (3) easier to manage immune-related adverse effects (irAEs) with dose adjustment; (4) relatively lower cost; and (5) higher permeability to distribute into targeted tissues.

"Immunogenicity and the poor permeability into tumor tissues are the major limitations of therapeutic antibodies, which can cause a low response rate of PD-1/PD-L1 antibodies. As a highly differentiated small molecule PD-L1 inhibitor, ASC61 showed promising safety profile in the dose escalation study in patients with advanced solid tumors in the U.S. so far. With two IND approvals in the U.S. and China, we expect to accelerate the global development of ASC61 and provide more options for patients with advanced solid tumors." said Dr. Jinzi J. Wu, Founder, Chairman and CEO of Ascletis.

On November 16, 2022 Genome Insight, a precision medicine whole genome platform company, and Kun-hee Lee Child Cancer & Rare Disease Project Team of SNUH (Seoul National University Hospital), funded by the family of ex-Samsung Group Chairman Kun-hee Lee, reported a collaborative study for a whole genome sequencing (WGS)-based approach to pediatric solid cancer diagnosis in the clinical setting (Press release, Genome Insight, NOV 16, 2022, View Source [SID1234624175]).

The partnership’s shared goal is to accelerate the widespread access and use of a WGS diagnosis platform in the clinical setting. Under their partnership, Genome Insight and Kun-hee Lee Child Cancer & Rare Disease Project Team will co-develop a pediatric solid cancer whole genome-based clinical system. This clinical system will cover from sample collection through multi-omics-based analysis to clinical utilization.

WGS captures a near-complete overview of the genomic characteristics of a tumor in one test. In contrast, targeted sequencing panels, a form of testing currently used in the clinical setting, selectively detects about 0.01%-1% of the genome due to technical limitations. The comprehensive WGS approach enables the discovery of all types of genomic mutations, including single nucleotide variants, copy number alterations, insertions/deletions, and structural variants as well as whole genome-wide pattern-based biomarkers such as mutational signature, homologous recombination deficiency, etc. These characteristics can inform diagnosis and treatment decisions but are often not detected through other medical testing.

Genome Insight will provide bioinformatics-powered digital solutions that read and translate a cancer patient’s genome into medically meaningful insights. Furthermore, Genome Insight’s web-based interactive user-friendly real-time report of genomic insights will replace the conventional paper-based reports. Through the implementation of this whole genome-based clinical system, the study aims to improve the quality and accuracy of pediatric solid cancer diagnosis and treatment selection.

"We are delighted to introduce a whole genome-based pediatric solid cancer diagnosis platform to our partner hospital through this collaboration. Our goal is to speed up the accumulation of whole genome datasets and real-world experience, thereby creating a world-class research cohort that would enhance our partner hospitals’ precision medicine research capabilities and bring better care to their patients through whole genome-based precision diagnosis," said Baek-lok Oh, Chief Medical Officer, Genome Insight.

"We expect that Genome Insight’s platform will have a positive impact on improving pediatric solid cancer diagnosis and treatment rates of pediatric cancer patients across Korea," said Professor Ji Hoon Phi, the principal investigator of this study.
