The offer expired one minute after 11:59 p.m. EDT on July 23, 2025. Under the terms of the offer, TriSalus provided holders of its Preferred Stock the option to exchange each preferred share for 3.3 shares of its common stock. As previously disclosed, parties representing approximately 55% of the shares of Preferred Stock have agreed to tender their shares of Preferred Stock in the Offer and to consent to the Preferred Stock Amendment in the Consent Solicitation pursuant to tender and support agreements

The company has been advised that the shares of Preferred Stock tendered represented approximately 98.82% of the outstanding shares of Preferred Stock. All validly tendered shares will be accepted, with settlement expected by August 1, 2025.

Because a sufficient percentage of preferred shareholders agreed to the offer, TriSalus received approval to amend the terms of the Preferred Stock. As a result, the remaining outstanding preferred shares will be automatically converted to common stock at a slightly lower exchange rate (11.3% less than the offered rate).

The SEC declared the company’s Registration Statement on Form S-4 (Registration No. 333-288250), originally filed with the SEC on June 23, 2025, registering the shares issuable in the offer and pursuant to the amendment to Preferred Stock was declared effective by the SEC on July 22, 2025.

TriSalus was assisted in the process by Sodali LLC (Information Agent) and Continental Stock Transfer & Trust Company (Exchange Agent).

Kling-Select is a proprietary, clinically and commercially validated B cell immortalization platform that has played a pivotal role in the discovery of potent neutralizing antibodies. By leveraging patient-derived B cells, Kling-Select enables rapid identification of novel antibodies and conserved viral epitopes, significantly enhancing vaccine and therapeutic design. Utilizing function-first screening workflow, Kling-Select uncovers rare and highly effective immune targets, accelerating the development of next-generation prophylactics and treatments. The platform’s proven success includes validated antibody candidates against RSV, COVID-19, and influenza, underscoring its broad utility and scientific impact.

The objective of the collaboration is to identify and characterize monoclonal antibodies with potent neutralizing activity against a clinically relevant human viral pathogen. Insights gained from this joint discovery effort may enable the development of next-generaton antiviral therapeutics and inform the design of more efficacious vaccine candidates.

"This collaboration with Sanofi highlights the broad potential of our Kling-Select platform to address global health challenges by enabling the discovery of first-in-class, human-derived antibodies," commented Michael Koslowski, MD, Chief Executive Officer of Kling Bio. "Kling-Select provides a powerful window into the human immune response and accelerates the identification of functional antibodies and novel epitopes. We are excited to combine our expertise with Sanofi’s leadership in vaccine development to advance next-generation therapeutics and vaccines."

On July 24, 2025 Anixa Biosciences, Inc. ("Anixa" or the "Company") (NASDAQ: ANIX), a biotechnology company focused on the treatment and prevention of cancer, reported that the United States Patent and Trademark Office (USPTO) will issue U.S. Patent Number 12,370,244 on July 29, 2025, covering key aspects of the Company’s breast cancer vaccine technology (Press release, Anixa Biosciences, JUL 24, 2025, View Source [SID1234654510]). The patent protects novel methods of immunizing patients against breast cancer by administering an immunogenic composition containing human α-lactalbumin protein—a protein typically found in breast tissue during lactation but also expressed in certain breast cancers, making it an attractive target for immunoprevention strategies.

Anixa’s breast cancer vaccine, developed in collaboration with Cleveland Clinic, represents a novel approach to the prevention and treatment of breast cancer. The vaccine was invented at Cleveland Clinic, and this patent—along with others related to this technology—has been exclusively licensed to Anixa Biosciences. This issuance builds upon the Company’s broad and expanding intellectual property portfolio, extending foundational patent protection for the breast cancer vaccine program into the mid-2040s. The expanded claims provide additional coverage for immunogenic formulations, further enhancing Anixa’s ability to develop and commercialize differentiated immunopreventive solutions.

Despite significant progress in breast cancer treatment, the disease remains the most commonly diagnosed cancer among women worldwide. In the United States alone, over 297,000 new cases of invasive breast cancer are projected in 2025, with approximately 43,000 women expected to die from the disease. No FDA-approved vaccine currently exists to prevent breast cancer, representing a major and unmet need in the field of preventive oncology.

Anixa’s investigational vaccine aims to stimulate the immune system to recognize and eliminate pre-malignant and malignant cells expressing α-lactalbumin—while sparing normal tissue. By targeting this "retired" protein, which is generally absent from adult tissues except during lactation, the vaccine has the potential to minimize off-target effects and provide long-lasting immune protection.

The breast cancer vaccine platform represents a potential multi-billion dollar market opportunity, particularly among women at elevated risk of developing triple-negative breast cancer (TNBC)—an aggressive subtype with limited treatment options and poor long-term prognosis. As clinical data and regulatory frameworks evolve, the technology may also have broader applications for average-risk populations.

"Our breast cancer vaccine program is a cornerstone of our long-term strategy to develop next-generation preventive immunotherapies, and this patent issuance further secures our leadership in this field," stated Dr. Amit Kumar, Chairman and CEO of Anixa Biosciences. "With a robust portfolio of issued and pending patents in the U.S. and internationally, we are well-positioned to bring forward a vaccine that could transform how we address breast cancer risk in healthy women."

On July 24, 2025 Pierre Fabre Pharmaceuticals Inc. (PFP) reported the acceptance by U.S. Food and Drug Administration (FDA) of the Biologics License Application (BLA) and Priority Review of tabelecleucel, indicated as monotherapy for treatment of adult and pediatric patients two years of age and older with Epstein-Barr virus positive post-transplant lymphoproliferative disease (EBV+ PTLD) who have received at least one prior therapy (Press release, Pierre Fabre, JUL 24, 2025, View Source [SID1234654509]).

Atara Biotherapeutics Inc. (Nasdaq: ATRA) resubmitted the tabelecleucel BLA on July 11, having in collaboration with PFP, swiftly addressed the third-party manufacturing facility observations outlined in the January 2025 Complete Response Letter.

"Patients diagnosed with relapsed or refractory EBV+ PTLD have no approved FDA treatment options, and following failure of initial therapy their survival is unfortunately measured in only weeks to months. Today’s BLA acceptance gives hope to these patients and is a significant step towards making this innovative cell therapy available in the United States," said Adriana Herrera, Chief Executive Officer of PFP, the Pierre Fabre Laboratories Pharmaceutical subsidiary in the U.S. "We are now completely focused on preparing for potential FDA approval of this innovative new treatment option."

Tabelecleucel is an allogeneic, off the shelf, EBV-specific T-cell immunotherapy which targets and eliminates EBV-infected cells. The BLA includes data covering more than 430 patients treated with tabelecleucel including the ongoing pivotal ALLELE study investigating the therapy in adults and children two years of age and older with relapsed or refractory EBV+ PTLD following SOT or HCT.

Tabelecleucel was granted marketing authorization under the brand name EBVALLO in December 2022 by the European Commission (EC). Marketing authorization was also granted by the Medicines and Healthcare Products Regulatory Agency in the United Kingdom in May 2023 and by Swissmedic in Switzerland in May 2024.

Since March 31, 2025, PFP has assumed global responsibility for tabelecleucel manufacturing of commercial product for European markets and for global clinical trial supply. On July 15, 2025, Atara Biotherapeutics transferred the tabelecleucel Investigational New Drug Application to Pierre Fabre Medicament, a subsidiary of Pierre Fabre Laboratories. As per the terms of the restated exclusive worldwide licensing agreement between Atara and Pierre Fabre Laboratories announced in November 2023, Atara is responsible for regulatory procedures up until BLA transfer to Pierre Fabre Pharmaceuticals.
