Malignant glioma of brain

MELBOURNE, Australia, Oct. 24, 2024 (GLOBE NEWSWIRE) -- Telix Pharmaceuticals Limited (ASX: TLX, Telix, the Company) today announces that the United States (U.S.) Food and Drug Administration (FDA) has accepted the New Drug Application (NDA) for TLX101-CDx (Pixclara®1), an agent for the imaging of glioma. The application has been granted priority review and designated a PDUFA2 goal date of 26 April 2025, paving the way for a U.S. commercial launch in 20253. Pixclara (18F-floretyrosine or 18F-FET) is a PET agent for the characterisation of progressive or recurrent glioma from treatment related changes in both adult and pediatric patients. FET PET is already included in international clinical practice guidelines for the imaging of gliomas4, however there is currently no FDA-approved targeted amino acid PET agent for adult and pediatric brain cancer imaging commercially available in the U.S. Given its potential to address significant unmet medical need, Pixclara has been designated as an orphan drug5 and granted fast track designation6 by the FDA. There is a critical unmet need to improve the diagnosis and management of gliomas, which are the most common primary brain tumours of the central nervous system, particularly in the post-treatment setting. Conventional MRI7 imaging techniques have several limitations, including a lack of biological specificity, dependency on blood-brain barrier disruption, and an inherent inability to differentiate between tumour progression or treatment-related causes. This can yield inconclusive results and delay time-sensitive treatment decisions8. With low survival rates and the need to make rapid decisions, precision imaging is paramount. Subject to regulatory approval, Pixclara has the potential to address this need, enabling patients in the U.S. to receive greater clarity in their diagnosis and treatment decision making. Telix is also reviewing the potential use of Pixclara as a “companion” diagnostic agent for TLX101-Tx, the investigational neuro-oncology drug currently in development, which targets the same amino acid transporter mechanism with therapeutic targeted radiation. Kevin Richardson, Chief Executive Officer, Telix Precision Medicine, said, “Telix believes that the FDA approval of Pixclara will drive a step-change for brain cancer imaging in the U.S., and bring it into line with a more advanced standard of care currently used in other markets. There is currently a critical need for better imaging in brain cancer, and Telix is dedicated to delivering precision medicine solutions that address patient needs and enhance both cancer imaging and treatment outcomes.” About TLX101-CDx TLX101-CDx (Pixclara) is a PET imaging agent, which has been granted fast track and orphan drug designations by the FDA as an imaging agent for the characterisation of glioma. TLX101-CDx targets membrane transport proteins known as LAT and LAT29. This enables Pixclara to be potentially utilised as a companion diagnostic agent to TLX101 (131I-iodofalan, or 131I-IPA), Telix’s LAT1-targeting investigational glioblastoma (GBM) therapy, currently under investigation in the Telix’s IPAX-210 and IPAX-Linz11 studies. About gliomas in the U.S. Gliomas are very diffusely infiltrative tumours that affect the surrounding brain tissue. They are the most common form of central nervous system (CNS) neoplasm that originates from glial cells, accounting for approximately 30% of all brain and CNS tumours and 80% of all malignant brain tumours12. In the U.S., there are six cases of gliomas diagnosed per 100,000 people every year. GBM is a high-grade glioma and the most common and aggressive form of primary brain cancer, with approximately 22,000 new cases diagnosed annually in the U.S.13. The mainstay of treatment for GBM comprises surgical resection, followed by combined radiotherapy and chemotherapy. Despite such treatment, recurrence occurs in almost all patients14, with an expected survival duration of 12-15 months from diagnosis15.

CHARLOTTE, NC, USA I September 04, 2024 I Adaptin Bio , a biotechnology company focused on developing precision cancer therapies with improved delivery to the brain and other tissues, has emerged from stealth today with the announcement that FDA has cleared an Investigational New Drug (IND) application for its APTN-101 program in glioblastoma (GBM), the most common and aggressive primary brain tumor. The clearance will enable the initiation of a first-in-human Phase 1 clinical trial to evaluate this investigational candidate in GBM. APTN-101 is a proprietary BRiTE (Brain Bispecific T cell Engager) therapeutic designed to target EGFRvIII, a specific protein linked to aggressive brain tumors. In preclinical studies, APTN-101 has shown a greater than 7-fold increase in distribution into the brain, with significant potential in eradicating malignant glioma tumors as a potentially best-in-class therapy. The Phase 1 clinical trial will assess the safety and efficacy of APTN-101 in patients diagnosed with WHO Grade IV Malignant Glioma, also known as GBM. Current treatment options for GBM include surgery, radiotherapy, and chemotherapy, which aim to remove or destroy tumor cells within the brain but fail to completely eliminate the disease due to its invasive nature. GBM deeply infiltrates the brain and despite aggressive treatment, residual tumor cells often lead to disease recurrence. GBM represents one of the most aggressive and challenging forms of brain cancer, with a median survival rate of just 12-18 months post-diagnosis, with only 5% of patients surviving beyond five years. The disease accounts for approximately 15,000 new cases per year in the US. Secondary malignant brain tumors account for about 200,000 new cases annually. This critical unmet need demands innovative therapies that can overcome the limitations of current treatments that do not cross the blood brain barrier. “The FDA clearance is a significant achievement for our collaboration with Adaptin. Based on results from preclinical models in orthotopic malignant glioma, we are excited to begin this clinical trial to evaluate the safety and efficacy of APTN-101,” said Mustafa Khasraw, M.D., Professor of Neurosurgery, Medicine, Integrative Immunobiology, Cancer Biology and Pharmacology at Duke University. “APTN-101’s ability to cross the blood-brain barrier and target glioma cells directly offers a promising new approach.” “We’re thrilled to initiate clinical trials with APTN-101 following FDA clearance of our first-in-human trial,” said Michael J. Roberts, Ph.D., CEO, Adaptin Bio. “Our proprietary BRiTE technology harnesses the immune system’s remarkable ability to target and deliver therapeutics to specific tissues, including the brain, potentially revolutionizing treatment for difficult-to-treat cancers. APTN-101 validates the BRiTE platform and its ability to enhance transfer of therapeutics into the brain. We are committed to advancing this novel therapy as a new potential therapy for glioblastoma patients who desperately need new therapies.” “Adaptin’s innovative delivery technology has the potential to revolutionize treatment for cancer and central nervous system disorders. We are proud to support Adaptin Bio as part of our ongoing commitment to partnering with visionary entrepreneurs and translating groundbreaking technologies from leading academic institutions into impactful solutions,” said James Ahern, Managing Partner of Laidlaw & Company and Founding Partner of Lucius Partners, who is an investor in Adaptin Bio. In preclinical studies, APTN-101 has shown impressive efficacy in eliminating malignant glioma tumors across various aggressive orthotopic models. The BRiTE platform, developed by researchers in the Department of Neurosurgery at Duke University under the leadership of Dr. John H. Sampson, harnesses the ability of T cells to precisely target and destroy glioma cells while effectively navigating the brain’s unique environment. Adaptin Bio’s proprietary BRiTE technology leverages the enhanced “hitchhiking” capabilities of manipulated immune cells to deliver therapeutic agents directly to brain tumors. This innovative approach has demonstrated high specificity for EGFRvIII expressing glioma cells, dose-responsive efficacy against diverse patient-derived glioma cell lines, and a favorable safety profile. Additional BRiTE targets are being evaluated. By manipulating the immune system either in vivo or ex vivo, BRiTE aims to overcome traditional treatment barriers and offer a promising new therapeutic option for patients with intracerebral malignancies. About Adaptin Bio Adaptin Bio is a biotechnology company developing novel therapies for oncology and central nervous system disorders with improved drug delivery to the brain and other tissues. The company’s proprietary Brain Bispecific T cell Engager (BRiTE) technology was developed by researchers at the Department of Neurosurgery at Duke University. The company’s mission is to develop novel therapies to improve patient outcomes in difficult-to-treat cancers. For more information, visit www.adaptinbio.com . SOURCE: Adaptin Bio

Allschwil, Switzerland, June 20, 2024 Basilea Pharmaceutica Ltd, Allschwil (SIX: BSLN), a commercial-stage biopharmaceutical company committed to meeting the needs of patients with severe bacterial and fungal infections, announced today that it has entered into an asset purchase agreement with the Glioblastoma Foundation Inc., for Basilea’s oncology drug candidate lisavanbulin (BAL101553), which has been developed as a potential therapy for glioblastoma, the most common type of primary brain cancer.1 Dr. Marc Engelhardt, Chief Medical Officer of Basilea, said: “Glioblastoma is one of the most lethal types of brain cancer and available therapeutic options are very limited. Partnering lisavanbulin with the Glioblastoma Foundation is important to us, as it enables patients to continue having access to this promising anticancer drug candidate, now that Basilea has changed its strategic focus to anti-infectives.” Dr. Gita Kwatra, Chief Executive Officer of the Glioblastoma Foundation, said: “We are delighted to partner with Basilea and take over the development of lisavanbulin for glioblastoma patients. Lisavanbulin has shown excellent activity against glioblastoma in PDX preclinical models as well as efficacy in phase 1 and 2 studies. We strongly believe that lisavanbulin will be effective in a subset of glioblastoma patients and we are looking forward to initiating clinical trials of lisavanbulin in the US.” Under the terms of the agreement, Basilea sells and transfers all rights to lisavanbulin to the Glioblastoma Foundation for an undisclosed initial purchase price. In addition, Basilea will participate in future proceeds from any potential commercial partnerships at a fixed double-digit percentage. The Glioblastoma Foundation will continue the post-trial access program for patients from previous clinical studies to continue to receive lisavanbulin. Also, the Glioblastoma Foundation will further explore the therapeutic value of lisavanbulin for the treatment of glioblastoma. About lisavanbulin (BAL101553) Lisavanbulin (BAL101553, the prodrug of BAL27862)2, has been investigated as a potential therapy for glioblastoma in clinical phase 1 and 2 studies.3, 4, 5 In preclinical studies, lisavanbulin demonstrated in-vitro and in-vivo activity against diverse treatment-resistant cancer models, including tumors refractory to conventional approved therapeutics and radiotherapy.6, 7, 8 Lisavanbulin efficiently distributes to the brain, with anticancer activity in glioblastoma models.9, 10 The active moiety, BAL27862, binds to the colchicine site of tubulin, with distinct effects on microtubule organization,11 resulting in the activation of the "spindle assembly checkpoint" which promotes tumor cell death.12 Lisavanbulin has been granted Orphan Drug Designation by the US Food and Drug Administration (FDA) for the treatment of malignant glioma (brain cancer), including glioblastoma. About Glioblastoma Foundation The mission of the Glioblastoma Foundation is to transform the standard of care for glioblastoma. It is based in Durham, North Carolina (USA) and supports the development of new drugs and other effective therapies for glioblastoma. Because each glioblastoma is different, it is likely that no one drug will work for everyone, and any therapies for glioblastoma will need to be targeted. The Glioblastoma Foundation supports the development of targeted therapies for glioblastoma. The organization also provides support for patients, and raises awareness of glioblastoma.
