"Having treated a number of patients with AUCATZYL as part of the FELIX clinical trial, I am delighted that we have moved closer to eligible relapsed/refractory B-ALL patients being able to access AUCATZYL," said Dr. Claire Roddie, MD, PhD, FRCPath, Lead investigator of the FELIX study and Associate Professor of Haematology at the University College London (UCL) Cancer Institute. "We now look forward to NICE completing its assessment of the medicine to potentially make it an option for eligible patients on the NHS."

"AUCATZYL was designed to address an unmet need for eligible adult r/r B-ALL patients and it is satisfying that is has been licensed in the country where it was created," said Dr. Martin Pule, Chief Scientific Officer and Founder of Autolus.

"Continuing our momentum, this MHRA license is a significant milestone for Autolus as a company. With our scientific expertise, operations and manufacturing based in the UK, this is an important achievement for our company," said Dr. Christian Itin, Chief Executive Officer of Autolus. "We want to thank all the patients and investigators at the UK trial centres for their contributions towards this license, as well as the foundational work by our partners at UCL and our internal team."

Obecabtagene autoleucel is an autologous CD19 CAR T cell therapy with a proprietary CD19 CAR, invented by a team led by Dr. Martin Pule, at University College London, along with collaborators at Great Ormond Street Hospital and University College London Hospital. The CAR is designed to have a "fast-off" rate which mimics physiological T-cell receptor interactions2.

The MHRA authorisation of AUCATZYL was based on the results of the FELIX study, an open-label, multi centre, single arm study in adult patients with relapsed or refractory B-cell acute lymphoblastic leukaemia, the results of which were published in the New England Journal of Medicine in November 20242. Of the 153 r/r B-ALL patients enrolled in the FELIX study, 127 (83.0%) received at least one obecabtagene autoleucel infusion and were evaluable. In the pivotal cohort of patients, (cohort IIA (n=94)), the Complete Response/Complete Response with Incomplete Haematological Recovery (CR/CRi) for patients who received at least one infusion of obecabtagene autoleucel was 76.6%. Median response duration for all infused patients was 21.2 months. Median event-free survival (EFS) was 11.9 months and the estimated 6- and 12-month event-free survival rates were 65.4% and 49.5%, respectively. The most common non-laboratory Grade 3 or higher adverse reactions were infections-pathogen unspecified (32%), febrile neutropenia (24%) and bacterial infectious disorders (11%). Cytokine release syndrome developed in 87 of the 127 patients (68.5%), with events of grade 3 or higher in three patients (2.4%). Immune effector cell-associated neurotoxicity syndrome developed in 29 of the 127 patients (22.8%), with grade 3 or higher occurring in nine patients (7%).

For further information regarding obecabtagene autoleucel, the Summary of Product Characteristics (SPC), including a full list of side effects and adverse reactions, is available here.

Autolus submitted obecabtagene autoleucel for appraisal by the National Institute for Health and Care Excellence (NICE)3 in Q4 2024 and is working with NICE and the NHS to potentially achieve access for eligible patients in England. NICE provides guidance to the NHS in England on the clinical and cost-effectiveness of medicines, treatments, and technologies based on a rigorous process of evidence review and consultation with professionals and patients.

ALL is an aggressive type of blood cancer that can also involve the lymph nodes, spleen, liver, central nervous system and other organs. In the UK there are approximately 7654 new cases of ALL diagnosed every year. In frontline treatment for adult B-ALL, up to 50% of patients will ultimately relapse5. Survival rates remain very poor in adult patients with r/r ALL, with median overall survival of eight months with conventional treatments6, and the standard-of-care treatment can trigger severe toxicities.

On April 25, 2025 Leap Therapeutics, Inc. (Nasdaq:LPTX), a biotechnology company focused on developing targeted and immuno-oncology therapeutics, reported it will present preclinical data of FL-501 in a poster presentation at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting taking place April 25-30 in Chicago, Illinois (Press release, Leap Therapeutics, APR 25, 2025, View Source [SID1234652153]).

FL-501 is a potential best-in-class monoclonal antibody targeting growth differentiation factor 15 (GDF-15), a cytokine that is implicated in multiple diseases and therapeutic areas, including cancer cachexia.

"Cancer cachexia is a devasting and potentially life-threatening condition characterized by significant weight loss, muscle wasting, fatigue, and severely reduced quality of life. It is a major contributor to cancer-related mortality, and unfortunately there are no effective treatment options available to patients," said Jason Baum, PhD, Chief Scientific Officer of Leap. "These data not only demonstrate that FL-501 is a novel and potential best-in-class anti-GDF-15 antibody, but also capable of fully restoring body composition in preclinical models that is comparable or better than other, clinical-stage antibodies. We look forward to progressing the development of FL-501 and bringing the asset into the clinic in 2026."

Key Findings:

In humanized FcRn mouse studies, FL-501 demonstrated a 2-3-fold longer half-life and 50% reduced clearance compared to its wild-type precursor and ponsegromab
In mouse cachexia models using GDF-15-overexpressing colorectal cancer cells, FL-501 fully restored body composition, comparably or better than clinical-stage antibodies visugromab and ponsegromab
In a non-small cell lung cancer patient-derived xenograft model, FL-501 effectively countered cisplatin-induced weight loss, restoring body weight, composition, and condition scores
These findings confirm GDF-15’s role in cachexia and support FL-501’s advancement in development

About FL-501
FL-501 is a potential best-in-class monoclonal antibody in preclinical development that targets growth differentiation factor-15 (GDF-15), a cytokine that is produced at elevated levels in response to various stresses, including chronic inflammation, obesity, cardiovascular diseases, cancers, and chemotherapy treatment. High GDF-15 expression is associated with cancer cachexia including loss of appetite, nausea and weight loss. FL-501 was engineered for higher affinity to GDF-15 and longer plasma half-life compared to competing therapies. In addition to cachexia, FL-501 may be able to reverse immunosuppression in cancers where elevated GDF-15 is correlated with poor survival, as well as play a role in treating other GDF-15-related diseases. FL-501 is being developed through a collaboration agreement with Adimab.

On April 25, 2025 Allarity Therapeutics, Inc. ("Allarity" or the "Company") (NASDAQ: ALLR), a Phase 2 clinical-stage pharmaceutical company dedicated to developing stenoparib—a differentiated, dual PARP and WNT pathway inhibitor—as a personalized cancer treatment using its proprietary, drug-specific Drug Response Predictor (DRP) patient selection technology reported the presentation of a poster containing data on a new DRP for the monoclonal antibody drug daratumumab (Press release, Allarity Therapeutics, APR 25, 2025, View Source [SID1234652152]). The poster is to be presented during a session at the 2025 American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting, taking place April 25–30, 2025, in Chicago, IL. This novel predictor is designed to identify multiple myeloma patients most likely to benefit from daratumumab.

The daratumumab DRP was developed by correlating gene expression patterns with sensitivity to daratumumab-induced antibody-dependent cellular cytotoxicity (ADCC), based on published in vitro data from multiple myeloma and B-cell lymphoma cell lines. From this analysis, the Company identified a total of 53 genes—27 associated with sensitivity and 26 with resistance—which form the basis of this drug-specific DRP. Using single-cell RNA sequencing data and overall response information from bone marrow samples collected in the KYDAR trial (a study of multiple myeloma patients treated with daratumumab in combination with carfilzomib, lenalidomide, and dexamethasone), the DRP was able to predict treatment outcomes and survival. These findings support the test’s potential as a patient enrichment tool.

"This is yet another successful application of our DRP technology beyond our internal clinical program pipeline," said Thomas Jensen, CEO of Allarity Therapeutics. "We already offer an extensive portfolio of DRPs for research use, and the addition of a DRP for daratumumab—our first developed for an antibody therapy—further demonstrates the versatility and flexibility of our DRP platform. Until now, our DRPs have been developed exclusively for small-molecule drugs. This new predictor expands the reach of our technology and positions us even better as a potential strategic partner for any third party seeking to target the right patients with existing cancer therapies. The data to be presented mark another important step toward potential future collaborations aimed at bringing precision diagnostics to more patients."

Daratumumab is approved by both the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for the treatment of multiple myeloma and marketed under the brand name Darzalex.

Allarity has already developed DRPs for investigational or research use for dozens of anticancer drugs covering a wide range of cancer types. This includes the company’s lead program, stenoparib, which is currently in Phase 2 development for advanced, recurrent, platinum-resistant or platinum-ineligible ovarian cancer, as well as in a combination study with temozolomide for recurrent small cell lung cancer.

The poster will be made available on Allarity’s website later today, following 1:00 p.m. ET, in the Scientific Publications section.

About Stenoparib
Stenoparib is an orally available, small-molecule dual-targeted inhibitor of PARP1/2 and tankyrase 1/2. At present, tankyrases are attracting significant attention as emerging therapeutic targets for cancer, principally due to their role in regulating the WNT signaling pathway. Aberrant Wnt/β-catenin signaling has been implicated in the development and progression of numerous cancers. By inhibiting PARP and blocking WNT pathway activation, stenoparib’s unique therapeutic action shows potential as a promising therapeutic for many cancer types, including ovarian cancer. Allarity has secured exclusive global rights for the development and commercialization of stenoparib, which was originally developed by Eisai Co. Ltd. and was formerly known under the names E7449 and 2X-121.

About the Drug Response Predictor – DRP Companion Diagnostic
Allarity uses its drug-specific DRP to select those patients who, by the gene expression signature of their cancer, may have a high likelihood of benefiting from a specific drug. By screening patients before treatment, and only treating those patients with a sufficiently high, drug-specific DRP score, the therapeutic benefit rate may be enhanced. The DRP method builds on the comparison of sensitive vs. resistant human cancer cell lines, including transcriptomic information from cell lines, combined with clinical tumor biology filters and prior clinical trial outcomes. DRP is based on messenger RNA expression profiles from patient biopsies. The DRP platform has shown an ability to provide a statistically significant prediction of the clinical outcome from drug treatment in cancer patients across dozens of clinical studies (both retrospective and prospective). The DRP platform, which may be useful in all cancer types and is patented for dozens of anti-cancer drugs, has been extensively published in the peer-reviewed literature.

Veracyte has begun making the Decipher Prostate Metastatic test available to select clinical sites through an early access program and will begin taking orders for the test more broadly in June 2025.

Prostate cancer is the second-leading cause of cancer deaths among men in the United States and the rate of men diagnosed with advanced disease has been growing in recent years.1 Veracyte estimates that approximately 10% (or about 30,000) of all prostate cancers diagnosed annually in the United States are metastatic.2

"A number of treatment options are now available to increase survival for patients whose prostate cancer has metastasized," said Elai Davicioni, Ph.D., Veracyte’s medical director for Urology. "Until now, however, clinicians had limited ways to determine which of these patients will likely benefit from these therapies and which will not and may thus avoid their toxic side effects. We believe the Decipher Prostate Metastatic test will provide an important new tool to help clinicians make more-informed treatment recommendations for their patients with metastatic prostate cancer."

The Decipher Prostate test’s clinical validity and clinical utility for use in patients with metastatic prostate cancer have been demonstrated in multiple, prospective, Phase 3 clinical studies.3-6 These studies have shown that such patients with high Decipher scores are likely to have more-aggressive tumor biology compared to those with lower scores, informing the absolute benefit from treatment intensification. These findings build upon extensive data already established for the Decipher Prostate test’s use in patients with localized prostate cancer, where it is the only gene expression test to achieve "Level I" evidence status in the most recent NCCN Guidelines* for prostate cancer.

"Our expansion into metastatic prostate cancer underscores the power of the Veracyte Diagnostics Platform to uncover novel insights that can enable us to further help patients," said Philip Febbo, M.D., Veracyte’s chief scientific officer and chief medical officer.

About Decipher Prostate

The Decipher Prostate Genomic Classifier is a 22-gene test, developed using RNA whole-transcriptome analysis and machine learning, that helps inform treatment decisions for patients across the full spectrum of prostate cancer. The test is performed on biopsy or surgically resected samples and conveys the aggressiveness of the cancer. For patients with localized or regional prostate cancer, the Decipher score indicates a patient’s risk of metastasis, helping to determine treatment timing and intensity. For patients with metastatic prostate cancer, the Decipher score indicates the likelihood of cancer progression and survival benefit with treatment intensification. Armed with this information, physicians can better personalize their patients’ care. The Decipher Prostate test’s performance and clinical utility has been demonstrated in over 85 studies involving more than 200,000 patients. It is the only gene expression test to achieve "Level I" evidence status and inclusion in the risk-stratification table in the most recent NCCN Guidelines* for prostate cancer.
