About aneurysmal Subarachnoid Hemorrhage (aSAH) aSAH is bleeding over the surface of the brain in the subarachnoid space between the brain and the skull, which contains blood vessels that supply the brain. A primary cause of such bleeding is the rupture of an aneurysm. Approximately 70% of aSAH patients experience death or dependence, and more than 30% die within one month of hemorrhage. Approximately 50,000 patients in the United States are affected by aSAH per year, based on market research. Outside of the United States, annual cases of aSAH are estimated at approximately 60,000 in the European Union, and approximately 150,000 in China. About the Grace Therapeutics Asset Portfolio GTx-104 is a clinical stage, novel, injectable formulation of nimodipine being developed for intravenous (IV) infusion in aSAH patients to address significant unmet medical needs. The unique nanoparticle technology of GTx-104 facilitates aqueous formulation of insoluble nimodipine for a standard peripheral IV infusion. GTx-104 provides a convenient IV delivery of nimodipine in the Intensive Care Unit potentially eliminating the need for nasogastric tube administration in unconscious or dysphagic patients. Intravenous delivery of GTx-104 also has the potential to lower food effects, drug-to-drug interactions, and eliminate potential dosing errors. Further, GTx-104 has the potential to better manage hypotension in aSAH patients. GTx-104 has been administered in over 150 healthy volunteers and was well tolerated with significantly lower inter- and intra-subject pharmacokinetic variability compared to oral nimodipine. The addressable market in the United States for GTx-104 is estimated to be about $300 million, based on market research. GTx-102 is a novel, concentrated oral-mucosal spray of betamethasone intended to improve neurological symptoms of Ataxia-Telangiectasia (A-T), for which there are currently no FDA-approved therapies. GTX-102 is a stable, concentrated oral spray formulation comprised of the gluco-corticosteroid betamethasone that, together with other excipients can be sprayed conveniently over the tongue of the A-T patient and is rapidly absorbed. The further development of GTx-102 has been deprioritized in favor of our focus on development of GTx-104. It is also possible that we may license or sell our GTx-102 drug candidate. GTx-101 is a non-narcotic, topical bio-adhesive film-forming bupivacaine spray designed to ease the symptoms of patients suffering with postherpetic neuralgia (PHN). GTx-101 is administered via a metered-dose of bupivacaine spray and forms a thin bio-adhesive topical film on the surface of the patient’s skin, which enables a touch-free, non-greasy application. It also comes in convenient, portable 30 ml plastic bottles. Unlike oral gabapentin and lidocaine patches, we believe that the biphasic delivery mechanism of GTx-101 has the potential for rapid onset of action and continuous pain relief for up to eight hours. No skin sensitivity was reported in a Phase 1 trial. The further development of GTx-101 has been deprioritized in favor of our focus on development of GTx-104. It is also possible that we may license or sell our GTx-101 drug candidate.

Pictured: MRI images of the brain for neurological Six months after treatment with the radiopharmaceutical therapy, 77.8% of patients with meningioma were alive and had not experienced further disease progression, beating the 26% benchmark established in earlier studies. Phase II data presented Sunday at the American Society for Radiation Oncology annual meeting suggest Novartis’ Lutathera may improve progression-free survival in patients with tough-to-treat meningioma brain tumors. Lutathera is a combination of a radionuclide, 177Lu, and a peptide that binds to somatostatin receptors. The combination enables the targeted delivery of radiation therapy. Lutathera received FDA approval for use against gastroenteropancreatic neuroendocrine tumors in 2018. Novartis has yet to expand the label to cover additional diseases but Lutathera is potentially applicable to other tumors that express somatostatin. That potential informed a Phase II trial led by Kenneth Merrell, a radiation oncologist at the Mayo Clinic Alix School of Medicine. The study was designed to show if Lutathera could be an option for people with meningioma, a brain tumor, who progress after treatment with surgery or radiation. Researchers have reported recurrence rates of 40% to 80% for certain grade meningiomas. As the tumor recurs, patients quickly run out of safe and effective salvage treatments. Because nearly all meningiomas express somatostatin, the Mayo Clinic oncologist identified Lutathera as a drug that could provide people with another option. “There is no standard of care or proven option for managing refractory meningioma,” Merrell said in a statement. “Many of these patients continue to experience aggressive tumor growth and significant related complications, and ultimately the illness may prove fatal. It is a very challenging prognosis to manage, and in many cases, we are left with only supportive measures.” The single-arm study enrolled 20 people with surgery- and radiation-refractory meningioma to receive four administrations of Lutathera eight weeks apart. Six months after treatment, 77.8% of the patients were alive and had not experienced further disease progression. The researchers said earlier studies had established 26% as the benchmark for progression-free survival (PFS) after six months. Median PFS in the Lutathera study was 10.7 months. The trial had yet to reach median overall survival at the time of the ASTRO analysis. One year after treatment, 88.5% of patients were alive. No patients experienced grade 4 or 5 adverse events, the most severe side effects, that were attributable to the treatment. Ten patients had moderate, grade 3 hematologic adverse events. There was also one case each of grade 3 hepatitis and seizure that were at least possibly attributable to treatment. Five people stopped taking Lutathera, in two cases because of possible treatment-related adverse events.

2024年9月13日至17日，一年一度的欧洲肿瘤内科学会(ESMO)大会在西班牙巴塞罗那召开。ESMO年会作为最负盛名、最有学术影响力的国际会议之一，每年均吸引了该领域的专家学者参加。石药集团在本届ESMO大会上展示了两个在研产品的两项最新临床试验进展。 一 研究名称：靶向VEGFR/CSF1R小分子抑制剂SYHA1813 治疗复发性胶质母细胞瘤的I期研究 入选类型：简短口头(Mini Oral) 入选编号：2032 研究简介：该项研究是由首都医科大学附属北京天坛医院李文斌教授牵头开展的一项开放、多中心、Ⅰ期临床研究，旨在评估SYHA1813在复发或晚期实体瘤患者的安全性、耐受性、药代动力学特征和初步疗效。 SYHA1813 是抗肿瘤1类候选新药，是一种新型VEGFR/CSF1R靶向小分子抑制剂，具有国内国际知识产权。SYHA1813不仅通过阻断VEGFR通路进而抑制肿瘤新生血管的形成，也同步靶向抑制CSF1R的激酶活性，重塑巨噬细胞极性，具有多环节拮抗肿瘤的潜力。在临床前研究中表现出对胶质母细胞瘤、肾癌、结直肠癌显著的抗肿瘤作用，动物体内药效优于同类VEGFR抑制剂阿昔替尼（辉瑞研发）。目前开展的I期临床试验中，该产品在复发的高级别脑胶质瘤和脑膜瘤患者中显示出积极的抗肿瘤疗效，在其他实体瘤领域的应用也在探索之中。 二 研究名称：抗HER2抗体KN026治疗HER2阳性晚期胃癌/胃食管结合部腺癌的II期临床研究 入选类型：壁报 入选编号：1425P 研究简介：该项研究是由中国人民解放军总医院徐建明教授牵头开展的一项多中心、开放II期临床试验，旨在评估KN026联合化疗对一线治疗失败的HER2阳性晚期不可切除或转移性胃癌/胃食管结合部腺癌患者的安全性和有效性。 KN026 KN026是一种靶向作用于HER2不同细胞外结构域 II(帕妥珠单抗结合位点)和 IV(曲妥珠单抗结合位点)的双特异性单克隆抗体。临床前研究显示，KN026 的抗肿瘤活性优于曲妥珠单抗或帕妥珠单抗单用时的抗肿瘤活性，且 KN026 的抗肿瘤活性与曲妥珠单抗和帕妥珠单抗联用时相似或更好。在对曲妥珠单抗或曲妥珠单抗+帕妥珠单抗耐药的某些细胞系中，KN026也显示出抗肿瘤活性。既往KN026单药治疗HER2阳性胃癌2期临床研究结果提示，KN026对于HER2阳性胃癌有初步抗肿瘤活性，安全性可控。本次公开的KN026联合化疗治疗HER2阳性胃癌2期阶段研究结果表明，在2线及以上HER2阳性胃癌/胃食管结合部腺癌患者中具有突出的疗效，安全性良好，已获得CDE突破性治疗认定。其3期阶段研究正在进行中。
