TU-7710

TU2218 is a potentially first-in-class dual inhibitor targeting transforming growth factor beta receptor 1 (TGFR1) and vascular endothelial growth factor receptor 2 (VEGFR2) The first patient with head and neck squamous cell carcinoma was dosed in the Phase 2a clinical trial of TU2218 The Phase 2a trial of TU2218 starts with head and neck squamous cell carcinoma, as well as biliary tract cancer patients. It will be later expanded to colorectal cancer patients BOSTON and SEONGNAM, South Korea, Oct. 4, 2024 /PRNewswire/ -- TiumBio Co., Ltd. (Kosdaq: 321550), a clinical-stage biopharmaceutical company focused on discovering and developing innovative therapeutics for patients with rare and incurable diseases, announced today that the first patient has been dosed in its Phase 2 clinical trial of TU2218. TU2218 is a novel oral dual inhibitor targeting TGFR1 and VEGFR2. TGF-ß and VEGF pathways are known to suppress the activity of immune checkpoint inhibitors (ICIs), so TU2218 is expected to improve the efficacy of ICIs by blocking the two pathways. In Phase 1a and 1b clinical trials, TiumBio evaluated the safety, pharmacokinetics, and pharmacodynamics of TU2218 as a monotherapy and in combination with Keytruda (pembrolizumab) in 41 patients with advanced solid tumors. These profiles were used to determine the dose levels for Phase 2 trials. The Phase 2a trial is designed to assess the safety and efficacy of TU2218 in combination with Keytruda in patients with head and neck squamous cell carcinoma (HNSCC), biliary tract cancer (BTC), and colorectal cancer (CRC). The Phase 2 trial begins at Seoul National University Hospital and Asan Medical Center in South Korea, which is planned to expand to hospitals in the United States. The first dose was administered to an HNSCC patient. HNSCC refers to malignant tumors that occur in the oral cavity, throat, larynx, or salivary glands. The standard treatment typically involves surgery and radiation therapy. According to Global Data, as of 2023, the number of HNSCC patients worldwide is estimated to be around 610,000, and it is expected to exceed 670,000 by 2030. "HNSCC is a disease with a high unmet medical need, as the average survival rate for first-line treatments is known to be only about one year," said Hun-taek Kim, Ph.D., MBA, CEO of TiumBio. "We have selected cancer types for the Phase 2 clinical trial based on other trials that demonstrated strong anti-cancer effects from targeting TGF- ß or VEGF pathways. Our goal is to develop TU2218 as a first-line treatment for HNSCC," he added. In the Phase 1b trial, among 10 patients with advanced solid tumors who received a 195mg daily dose (the determined dose for Phase 2) of TU2218 with Keytruda, three patients achieved partial response (PR) and five patients had stable disease (SD), yielding an 80% disease control rate (DCR).

TU7710, long-acting recombinant activated factor VII, demonstrated a 5 to 7 times longer half-life in a Phase 1 study than that of NovoSeven, a conventional hemophilia treatment for patients who develop inhibitors TiumBio presented interim Phase 1a clinical data of TU7710 and discussed potential partnership at the ISTH 2024 SEONGNAM, South Korea, June 24, 2024 /PRNewswire/ -- TiumBio Co., Ltd. (Kosdaq: 321550), a clinical-stage biopharmaceutical company focused on discovering and developing innovative therapeutics for patients with rare and incurable diseases, announced today that the company presented clinical outcomes of its hemophilia treatment, TU7710, at the 32nd Congress of the International Society on Thrombosis and Haemostasis (ISTH) and embarked on building new global partnerships. TiumBio is currently conducting a double-blind, placebo-controlled Phase 1a clinical trial evaluating the pharmacokinetics, pharmacodynamics, and safety of TU7710 in healthy adult males. At the conference, interim results were presented for a total of 32 participants across cohorts ranging from 100 μg/kg (Cohort 1) to 800 μg/kg (Cohort 4) dosing groups. In the clinical results presented at the ISTH conference, TU7710 showed an average half-life ranging from 10.4 to 16.6 hours across dosage groups. This is 5 to 7 times longer than that of NovoSeven, a conventional hemophilia drug for patients with neutralizing antibodies against standard therapies, which has a known half-life of 2.3 hours. Furthermore, no serious adverse and thromboembolic events occurred, and most of adverse events were mild. Half-life refers to the time it takes for the blood concentration of a drug to decrease by half and is related to the sustainability of drug efficacy. Due to its short half-life, when bleeding occurs, hemophilia A or B patients with inhibitors are recommended to receive NovoSeven every two hours until hemostasis is achieved, which places a burden on patients and healthcare providers. TU7710 is recombinant factor VIIa with an extended half-life developed by TiumBio's transferrin fusion technology. TiumBio plans to initiate a Phase 1b clinical trial of TU7710 in hemophilia patients in Europe in the second half of this year. "NovoSeven has been widely used for hemophilia patients, bringing in $10 billion in sales over the past 9 years. However, due to its short half-life, there are significant unmet medical needs for patients and healthcare professionals," said Hun-Taek Kim, Ph.D., MBA, CEO at TiumBio. "The extended half-life of TU7710 has been demonstrated in preclinical and first-in-human studies, which further enhances the commercial value of the novel drug," he added. About TiumBio Co., Ltd.
