Affinia Therapeutics to Present New Data on its AFTX-201 Program in BAG3 Dilated Cardiomyopathy, BBB-Penetrant AAV Capsids, and Proprietary Manufacturing Technology at the 28th Annual American Society of Gene & Cell Therapy 2025 Annual Meeting
WALTHAM, Mass.--(BUSINESS WIRE)--Apr 28, 2025--
Affinia Therapeutics ('Affinia'), an innovative gene therapy company with a pipeline of first-in-class and/or best-in-class adeno-associated virus (AAV) gene therapies for devastating cardiovascular and neurological diseases, today announced that new preclinical data on AFTX-201, its lead program for BAG3 dilated cardiomyopathy (DCM), as well as its novel AAV capsids for diseases of the central nervous system (CNS), and the company's high-yield manufacturing process, will be presented in several oral and poster sessions at the 28 th Annual American Society of Gene and Cell Therapy (ASGCT) 2025 Annual Meeting, being held May 13-17, 2025 in New Orleans, LA and virtually.
Affinia has rationally designed novel capsids and gene therapies with increased tropism for cardiac muscle, skeletal muscle, or CNS and more uniform tissue distribution than AAV9. This improved biodistribution is attained at doses that are greater than 10-fold lower than those used with conventional capsids such as AAV9 while detargeting the liver and dorsal root ganglia, both potential sites of toxicity. Furthermore, Affinia has developed a proprietary plasmid design system that results in multi-fold improvement in manufacturing yields across a range of novel and conventional capsids and payloads.
AFTX-201, a potential best-in-class investigational gene therapy intended to be given as a simple one-time intravenous (IV) administration, is undergoing investigational new drug (IND)-enabling studies. Affinia has completed a successful pre-IND meeting with the U.S. Food and Drug Administration (FDA) and plans to file an IND in the fourth quarter of 2025. BAG3 DCM is a devastating monogenic heart disease affecting more than 70,000 patients in the U.S., Europe, and U.K. regions alone. The BAG3 gene, or Bcl2-associated athanogene 3, encodes for a protein that is critical to the normal structure and function of heart cells. Patients affected by BAG3 DCM have a mutation in the BAG3 gene and a deficiency in functioning BAG3 protein, resulting in early onset heart failure that progresses rapidly. Despite current standard of care, almost 25% of patients require a heart transplant. AFTX-201 is designed to deliver a fully human, full-length BAG3 transgene using Affinia's novel cardiotropic capsid. Preclinical studies with AFTX-201 have shown correction of BAG-3 protein levels in the heart and complete restoration of cardiac function, whereas such benefits were not achieved with the same gene construct using a conventional capsid at the same dose.
'We look forward to unveiling data on AFTX-201, our lead program for BAG3 DCM, as well as our high-yield manufacturing process and our BBB-penetrant capsids,' said Rick Modi, Affinia's Chief Executive Officer. 'Affinia's purpose is to bring potentially curative treatments to patients affected by devastating diseases. In the near-term, we're focused on advancing our AFTX-201 investigational program into the clinic and evaluating multiple endpoints that have been shown, for other cardiovascular drugs and diseases, to demonstrate efficacy as early as one-to-three months post-dose.'
The oral and poster presentation details are provided below. Abstracts can be found at https://annualmeeting.asgct.org/. Updated data, new graphics, and follow up information to be presented are embargoed until 6:00 AM CT on the presentation day for oral abstracts and until 6:00 AM CT on May 13, 2025 for poster abstracts.

H.C. Wainwright Reiterates Buy Rating on Immix Biopharma (IMMX) Following Promising Interim Results from NXC-201 Trial
On June 4, analyst Robert Burns of H.C. Wainwright reiterated a Buy rating on Immix Biopharma, Inc. (NASDAQ:IMMX) with a price target of $7.00. The analyst based the rating on the promising interim results from the NEXICART-2 Phase 1/2 clinical trial of NXC-201, presented at the 2025 American Society of Clinical Oncology Annual Meeting (ASCO 2025) in Chicago, Illinois. The trial assessed the efficacy of NXC-201 in patients with relapsed/refractory AL amyloidosis and delivered a 100% response rate, with a considerable portion attaining a complete hematologic response. The analyst reasoned that the absence of hematologic relapse or progression and the rapid mean time to response further highlight NXC-201's potential as a viable treatment. A doctor in a white coat discussing clinical trial results with a patient in an oncology practice. Burns also reasoned that NXC-201 appears to have a favorable safety profile, as no patients experienced severe cytokine release syndrome or neurotoxicity. While he highlighted the need for longer-term follow-up and the small sample size, the analyst stated that the interim results are promising when compared to existing treatments. This condition does not have FDA-approved agents, and there exists a fragmented treatment landscape post-frontline therapy, factors that suggest the notable market opportunity for NXC-201 and support the buy rating for Immix Biopharma, Inc. (NASDAQ:IMMX). Immix Biopharma, Inc. (NASDAQ:IMMX) is a biopharmaceutical company that develops therapies for inflammatory diseases and cancer. While we acknowledge the potential of IMMX as an investment, our conviction lies in the belief that some AI stocks hold greater promise for delivering higher returns and have limited downside risk.

Cameco Reports Expected Increase in Its Share of Westinghouse 2025 Adjusted EBITDA
All amounts in Canadian dollars unless specified otherwise SASKATOON, Saskatchewan, June 06, 2025--(BUSINESS WIRE)--Cameco (TSX: CCO; NYSE: CCJ) reports an expected increase of approximately $170 million (US) in our 49% equity share of Westinghouse Electric Company's (Westinghouse) 2025 second quarter and annual adjusted EBITDA. The expected increase is tied to Westinghouse's participation in the construction project for two nuclear reactors at the Dukovany power plant in the Czech Republic. This expected increase will be taken into consideration in determining the 2025 distribution payable by Westinghouse to Cameco. In addition to the increase in adjusted EBITDA in 2025, we expect significant financial benefits for Westinghouse, as a subcontractor, over the term of the Dukovany construction project and related to the provision of the fuel fabrication services required for both reactors for a specified period. The outlook for Westinghouse's compound annual growth rate for adjusted EBITDA remains 6% to 10% over the next five years, excluding the impact of the expected $170 million (US) increase in its 2025 adjusted EBITDA. Cameco owns a 49% interest in Westinghouse and its partner, Brookfield Renewable Partners, owns the remaining 51%. Caution about forward-looking informationThis news release includes statements and information about our expectations for the future, which we refer to as forward-looking information. Forward-looking information is based on our current views, which can change significantly, and actual results and events may be significantly different from what we currently expect. Examples of forward-looking information in this news release include our expectations regarding: Westinghouse's participation in the Dukovany power plant construction project; an increase in Westinghouse's adjusted EBITDA; Westinghouse taking this increase into consideration in determining the 2025 distribution payable to Cameco; the financial benefits for Westinghouse, as subcontractor, over the term of the Dukovany construction project and the expected future growth in Westinghouse's compound annual growth rate for adjusted EBITDA. Material risks that could lead to different results include the risk that Westinghouse is not able to participate in the Dukovany construction project on a basis that achieves the currently expected benefits to Westinghouse for any reason, or that Cameco may not derive the expected increases in its share of Westinghouse's adjusted EBITDA, or that Westinghouse does not achieve the expected future annual growth in adjusted EBITDA. In presenting the forward-looking information, we have made material assumptions which may prove incorrect about Westinghouse's participation in the Dukovany construction project and related potential benefits to Westinghouse, and continuing growth in Westinghouse's compound annual growth rate for adjusted EBITDA. Non-IFRS MeasuresAdjusted EBITDA is a measure that does not have a standardized meaning or a consistent basis of calculation under International Financial Reporting Standards (a non-IFRS measure). Westinghouse's adjusted EBITDA is defined as its net income, adjusted for the impact of certain expenses, costs, charges or benefits incurred in such period which are either not indicative of underlying business performance or that impact the ability to assess the operating performance of its business. For more information regarding our use of this non-IFRS measure see our most recent annual and quarterly Management's Discussion and Analysis. ProfileCameco is one of the largest global providers of the uranium fuel needed to power a secure energy future. Our competitive position is based on our controlling ownership of the world's largest high-grade reserves and low-cost operations, as well as significant investments across the nuclear fuel cycle, including ownership interests in Westinghouse Electric Company and Global Laser Enrichment. Utilities around the world rely on Cameco to provide global nuclear fuel solutions for the generation of safe, reliable, carbon-free nuclear power. Our shares trade on the Toronto and New York stock exchanges. Our head office is in Saskatoon, Saskatchewan, Canada. As used in this news release, the terms we, us, our, the Company and Cameco mean Cameco Corporation and its subsidiaries unless otherwise indicated.
