Avvio Medical's Microbubble Technology Reduces Complications and Shows Promise for Enhancing Laser Lithotripsy: AEROLITH Trial Results Published in
Study highlights include:
The AEROLITH study demonstrated that in the ureteral stone subgroup, a key clinical population, efficacy was comparable between URS-LL with microbubbles and URS-LL alone. However, the use of microbubbles demonstrated a significant safety advantage, including a 42% relative reduction in adverse events. 'This study demonstrates that conventional URS-LL, which currently is the most common surgical procedure to treat stones, yields disappointing results. More than 50% of patients will still have stones after the procedure, with residual fragments large enough to have a high chance for future problems,' stated Wesley Mayer, MD, lead author of the study. 'It is also poorly tolerated, with > 40% of patients reporting adverse events. AEROLITH showed that patients undergoing URS-LL augmented with microbubbles had significantly fewer adverse events, suggesting improved safety and tolerability compared to conventional laser lithotripsy.'
These clinical findings further strengthen the growing body of evidence supporting Avvio's proprietary technology. Avvio Medical is also currently evaluating, in a pivotal multi-center clinical trial, the safety and effectiveness of Acoustic Enhancer Microbubbles delivered with its breakthrough Enhanced Lithotripsy System (ELS) utilizing low-intensity therapeutic ultrasound.

Aqtual Raises Over $30M as It Scales Novel cfDNA Platform
HAYWARD, Calif.--(BUSINESS WIRE)-- Aqtual, Inc., a precision medicine company using its novel active chromatin cell-free DNA (cfDNA) platform to develop products for chronic diseases and oncology, today announced it has raised $31 million in Series B funding. Three new investors, including Bold Capital and Bold Longevity Growth Fund, joined previous investors Genoa Ventures, Manta Ray Ventures, and Yu Galaxy in participating in the oversubscribed round. Additional capital was also provided by a strategic investor in the diagnostics space, further strengthening Aqtual's ability to advance the platform and its applications as it moves towards the commercialization of Aqtual's first flagship product: a therapy response prediction test in rheumatoid arthritis (RA). Aqtual is actively enrolling RA patients in a prospective observational clinical trial, PRIMA-102 (ID NCT05936970). The trial, with more than 1,300 patients enrolled, has delivered initial proof-of-concept data and is expected to be completed in Q4 2025. RA treatment remains highly individualized, with many patients cycling through multiple therapies before achieving disease control. In the U.S. alone, RA contributes over $19 billion annually in direct healthcare costs, excluding the broader burden of reduced quality of life, disability, and premature mortality. 'The Aqtual team combines deep technical brilliance with remarkable resilience and ingenuity,' said Lawrence Barclay, Managing Partner at Manta Ray. 'Over the past year, we've seen powerful signals of technical and early commercial validation – not only in their lead indication, but across a broad range of chronic diseases and cancers – demonstrating the platform's potential for wide-reaching impact in molecular diagnostics. It's been a pleasure to work with them over the years, and Manta Ray is excited to support this next pivotal step toward commercialization.' Aqtual's proprietary active chromatin cfDNA platform is the first to integrate DNA, epigenetic regulation, and protein-DNA binding in a single, blood-based assay. Its proprietary approach enables high-fidelity quantification of tissue-specific gene regulation directly from blood through integrated profiling of disease, microenvironment, and systemic immune response. 'This raise marks a key inflection point for cfDNA diagnostics—not just for Aqtual, but for the broader field,' said Diana Abdueva, Ph.D., co-founder and CEO of Aqtual. 'Our platform uniquely captures the biology of chronic disease, enabling deeper insights to support more effective treatment planning strategies. With this funding, strengthened by backing from a strategic partner, we're positioned to advance our internal pipeline and forge new partnerships that extend the impact of our platform across disease areas.' Aqtual will present new data and commercialization plans at major rheumatology and diagnostics meetings in the second half of 2025, including the Congress of Clinical Rheumatology (CCR) West, the Coalition of State Rheumatology Organizations (CSRO) Advocacy Conference, and American College of Rheumatology (ACR) Convergence 2025.

Stoke Therapeutics and Biogen Announce Presentation of Data from Studies of Zorevunersen, an Investigational Medicine for Dravet syndrome, at the 16th European Paediatric Neurology Society (EPNS) Congress
BEDFORD, Mass., & CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Stoke Therapeutics, Inc. (Nasdaq: STOK), a biotechnology company dedicated to restoring protein expression by harnessing the body's potential with RNA medicine, and Biogen Inc. (Nasdaq: BIIB) today announced the presentation of data from an analysis that informed the design of the Phase 3 EMPEROR study and evaluated the potential effects of the Phase 3 zorevunersen dosing regimen. The data are complementary to previously reported data from a broader cohort of patients treated with zorevunersen in the Phase 1/2a and open label extension (OLE) studies that showed improvements within the first 9 months and continuing improvements through an additional two years. The new analysis is best aligned with the timing and dosing regimen that will be evaluated in the pivotal Phase 3 EMPEROR study and showed improvements in multiple measures of cognition and behavior at Week 68. The results contrasted with findings from a natural history study in which patients with Dravet syndrome were treated with standard of care medicines. Zorevunersen is in development as a first-in-class potential disease modifying treatment for Dravet syndrome. Results were presented as part of the Epilepsy II session at the 16th European Paediatric Neurology Society (EPNS) Congress. "Dravet syndrome is a complex neurodevelopmental disorder that has significant impacts on patients and their families,' said Dr. Andreas Brunklaus, Consultant Paediatric Neurologist at the Royal Hospital for Children in Glasgow, Honorary Professor at the University of Glasgow, and a zorevunersen study investigator. 'Natural history data shows the limitations of treating this disease with anti-seizure medicines. The zorevunersen data give us early evidence that this new genetically-targeted approach could address the underlying cause of Dravet syndrome, resulting in additional seizure control and offer patients the opportunity to experience improvements in cognition and behavior." Previously presented data from the two Phase 1/2a and OLE studies showed substantial and durable reductions in major motor seizure frequency on top of a background of standard anti-seizure medicines and improvements in multiple measures of cognition and behavior through two years of treatment in the OLE studies. Data indicated responses may be better among patients who were treated with loading doses of 70mg followed by maintenance doses of 45mg. Zorevunersen was generally well-tolerated across these studies. "Effects on behavior and cognition are a key secondary endpoint in our Phase 3 EMPEROR study," said Barry Ticho, M.D., Ph.D., Chief Medical Officer of Stoke Therapeutics. 'Feedback from caregivers and clinicians, and analyses like this one, give us insight into which assessments have the greatest potential to demonstrate meaningful effects for patients within the year-long treatment period.' 'Most patients with Dravet syndrome continue to experience seizures despite treatment with the best available anti-seizure medicines, and there are currently no medications approved that address the underlying cognitive and behavioral aspects of the disease,' said Katherine Dawson, M.D., Head of the Therapeutics Development Unit at Biogen. 'We look forward to continuing to work together to advance zorevunersen as a potential first-in-class disease modifying medicine for Dravet syndrome.' Dravet syndrome is a severe developmental and epileptic encephalopathy (DEE) that is characterized by severe, recurrent seizures as well as significant cognitive and behavioral impairments. There are no approved disease-modifying therapies for people living with Dravet syndrome. Currently, it is estimated that up to 38,000 people are living with Dravet syndrome in the United States (~16,000), United Kingdom, EU-4 (Germany, France, Italy, Spain) and Japan. 1 Description of the Modeled Analysis A mixed-effects model for repeated measures (MMRM) analysis was used to evaluate the potential effects of the Phase 3 zorevunersen dosing regimen on patient cognition and behavior at Week 68. The model was developed using clinical data from patients in the Phase 1/2a ADMIRAL study and the LONGWING OLE study. An analysis of patients who received a total cumulative dose consistent with the Phase 3 EMPEROR regimen of two loading doses of 70mg followed by two maintenance doses of 45mg, showed improvements in cognition and behavior. The analysis was performed to inform the design of the Phase 3 EMPEROR study. Baseline covariates for patients followed in the BUTTERFLY natural history study were matched to the selected ADMIRAL patient population. Improvements in patients treated with zorevunersen contrasted with findings from BUTTERFLY. These data support the selection of five sub-domains of the Vineland-3 Adaptive Behavior Scales, including Receptive Communication, Expressive Communication, Interpersonal Relationships, Coping Skills, and Personal Skills now under evaluation as key secondary endpoints in the Phase 3 EMPEROR study. Details of the presentation are as follows: Title: Zorevunersen demonstrates potential as a disease modifying therapy in patients with Dravet syndrome through durable seizure reduction and improvements in cognition, behavior, and functioning with up to 24 months of maintenance dosing in open-label extension studies Presenter: Andreas Brunklaus, M.D., Consultant Paediatric Neurologist at the Royal Hospital for Children, Glasgow, Honorary Professor at the University of Glasgow Session: Epilepsy II Date/Time: Thursday, July 10, 11:51 AM CEST Location: Saal 5, International Congress Center München, Germany The presentation will be available for download on the Stoke Therapeutics website under the Investors & News tab. About Dravet Syndrome Dravet syndrome is a severe developmental and epileptic encephalopathy (DEE) characterized by severe, recurrent seizures as well as significant cognitive and behavioral impairments. Most cases of Dravet are caused by mutations in one copy of the SCN1A gene, leading to insufficient levels of NaV1.1 protein in neuronal cells in the brain. More than 90 percent of patients continue to experience seizures despite treatment with the best available anti-seizure medicines. Complications of the disease often contribute to a poor quality of life for patients and their caregivers. Developmental and cognitive impairments often include intellectual disability, developmental delays, movement and balance issues, language and speech disturbances, growth defects, sleep abnormalities, disruptions of the autonomic nervous system and mood disorders. Compared with the general epilepsy population, people living with Dravet syndrome have a higher risk of sudden unexpected death in epilepsy, or SUDEP. Dravet syndrome occurs globally and is not concentrated in a particular geographic area or ethnic group. Currently, it is estimated that up to 38,000 people are living with Dravet syndrome in the U.S. (~16,000), UK, EU-4 and Japan. 1 About Zorevunersen Zorevunersen is an investigational antisense oligonucleotide that is designed to treat the underlying cause of Dravet syndrome by increasing NaV1.1 protein production in brain cells from the non-mutated (wild-type) copy of the SCN1A gene. This highly differentiated mechanism of action aims to reduce seizure frequency beyond what has been achieved with anti-seizure medicines and to improve neurodevelopment, cognition, and behavior. Zorevunersen has demonstrated the potential for disease modification and has been granted orphan drug designation by the FDA and the EMA. The FDA has also granted zorevunersen rare pediatric disease designation and Breakthrough Therapy Designation for the treatment of Dravet syndrome with a confirmed mutation not associated with gain-of-function, in the SCN1A gene. Stoke has a strategic collaboration with Biogen to develop and commercialize zorevunersen for Dravet syndrome. Under the collaboration, Stoke retains exclusive rights for zorevunersen in the United States, Canada, and Mexico; Biogen receives exclusive rest of world commercialization rights. About Stoke Therapeutics Stoke Therapeutics (Nasdaq: STOK), is a biotechnology company dedicated to restoring protein expression by harnessing the body's potential with RNA medicine. Using Stoke's proprietary TANGO (Targeted Augmentation of Nuclear Gene Output) approach, Stoke is developing antisense oligonucleotides (ASOs) to selectively restore naturally-occurring protein levels. Stoke's first medicine in development, zorevunersen, has demonstrated the potential for disease modification in patients with Dravet syndrome and is currently being evaluated in a Phase 3 study. Stoke's initial focus are diseases of the central nervous system and the eye that are caused by a loss of ~50% of normal protein levels (haploinsufficiency). Proof of concept has been demonstrated in other organs, tissues, and systems, supporting broad potential for Stoke's proprietary approach.
