Tharimmune Advances TH104 for Prophylaxis Against Weaponized Fentanyl and Other High-Potency Opioids Following Positive FDA Feedback
BRIDGEWATER, NEW JERSEY / ACCESS Newswire / April 28, 2025 / Tharimmune, Inc., (Nasdaq:THAR) ('Tharimmune' or the 'Company') a clinical-stage biopharmaceutical company focused on developing innovative therapeutics in inflammation & immunology, recently announced positive feedback from the U.S. Food and Drug Administration (FDA) regarding TH104. The agency confirmed that no additional clinical trials appear to be necessary prior to a 505(b)(2) New Drug Application (NDA) submission. TH104 is a buccal film formulation, of nalmefene specifically designed for rapid absorption with a potential for bypassing liver metabolism. This allows TH104 to be suitable for the temporary prophylaxis of respiratory and/or nervous system depression in military personnel and chemical incident responders who may be exposed to high-potency opioids, including weaponized fentanyl and its analogues.
This significant regulatory milestone underscores the urgent need for specialized medical countermeasures highlighted in a recent market assessment concerning the United States Strategic National Stockpile (SNS). This assessment specifically addressed the growing threat posed by chemicals of concern, with a primary focus on the increasing risk of high-potency synthetic opioids like fentanyl and its numerous derivatives being weaponized and deployed as aerosolized agents.
The U.S. government has increasingly recognized fentanyl and its related compounds as significant national security threats due to their extreme potency and the potential for mass casualty incidents if weaponized. These substances, significantly more potent than traditional opioids, pose a grave risk through inhalation, dermal contact, or ingestion. The 2002 Moscow theater hostage crisis, where aerosolized synthetic opioids were reportedly used, tragically demonstrated the devastating potential of such agents in a mass casualty scenario. This event, alongside intelligence indicating potential adversary interest in opioid-based chemical weapons, has heightened the priority for developing effective prophylactic measures for frontline personnel/first responders.
SNS market assessment identified a critical need for countermeasures that can be administered prior to or immediately upon potential exposure to these agents, preventing or mitigating the rapid onset of respiratory and nervous system depression. Key findings from this analysis further emphasize the importance of Tharimmune's work:
'The positive feedback from the FDA on the NDA pathway for TH104 is a crucial step forward in addressing a critical national security concern - the potential weaponization of fentanyl and its derivatives,' said Randy Milby, CEO of Tharimmune. 'The market assessment clearly articulates the need for more options as effective prophylactic solutions for those on the front lines. TH104's novel formulation and pharmacokinetic profile could provide a significant advantage in protecting military personnel and chemical incident responders from the immediate and life-threatening effects of opioid exposure in contaminated environments.'
The development of TH104 aligns directly with the U.S. government's increasing focus on preparedness against chemical threats, particularly those involving highly potent opioids. The positive FDA feedback provides a clear impetus for Tharimmune to continue its development program and work towards making this potentially life-saving prophylactic available to those who need it most.

BioNTech Announces Strategic Transaction to Acquire CureVac in Public Exchange Offer
Acquisition will strengthen the research, development, manufacturing and commercialization of mRNA-based cancer immunotherapy candidates, marking BioNTech's next key milestone in the execution of its oncology strategy Acquisition of CureVac will complement BioNTech's capabilities and proprietary technologies in mRNA design, delivery formulations, and mRNA manufacturing Public exchange offer for all shares of CureVac where each share of CureVac will be exchanged for approx. $5.46 in BioNTech American Depositary Shares ('ADSs'), representing a premium of 55% to CureVac's three-month volume weighted average price of approx. $3.53 as of June 11, 2025 All-stock acquisition has potential to create long-term value for both companies' shareholders given their complementary capabilities, focus on mRNA innovation, and shared vision Transaction is supported by CureVac's major shareholder dievini Hopp BioTech holding GmbH & Co. KG and certain of its affiliates and expected to close in 2025 MAINZ and TÜBINGEN, Germany, June 12, 2025 (GLOBE NEWSWIRE) -- BioNTech SE (Nasdaq: BNTX, 'BioNTech') and CureVac N.V. (Nasdaq: CVAC, 'CureVac') today announced that they have entered into a definitive Purchase Agreement pursuant to which BioNTech intends to acquire all of the shares of CureVac, a clinical-stage biotech company developing a novel class of transformative medicines in oncology and infectious diseases based on messenger ribonucleic acid ('mRNA'). The all-stock transaction will bring together two highly complementary companies based in Germany and will build on BioNTech's proven track record and established position in the global mRNA industry. With the acquisition, BioNTech aims to strengthen the research, development, manufacturing, and commercialization of investigational mRNA-based cancer immunotherapy. The strategic transaction will complement BioNTech's capabilities and proprietary technologies in mRNA design, delivery formulations, and mRNA manufacturing. For BioNTech, this transaction marks the next milestone in the execution of its oncology strategy which focuses on two pan-tumor programs, mRNA-based cancer immunotherapy candidates, and BNT327, a PD-L1xVEGF-A bispecific antibody candidate. Under the terms of the Purchase Agreement, each CureVac share will be exchanged for approx. $5.46 in BioNTech ADSs, resulting in an implied aggregate equity value for CureVac of approx. $1.25 billion (subject to the adjustments described below). The consideration is subject to a collar mechanism, such that if the 10-day volume weighted average price of the BioNTech ADSs ending on the fifth business day prior to the closing of the offer ('VWAP') exceeds $126.55, the exchange ratio would be 0.04318, and if the VWAP is lower than $84.37, the exchange ratio would be 0.06476. Upon closing of the transaction, CureVac shareholders are expected to own between 4% and 6% of BioNTech. 'This transaction is another building block in BioNTech's oncology strategy and an investment in the future of cancer medicine,' said Prof. Ugur Sahin, M.D., CEO and Co-Founder of BioNTech. 'We intend to bring together complementary capabilities and leverage technologies with the goal of advancing the development of innovative and transformative cancer treatments and establishing new standards of care for various types of cancer in the coming years.' 'To me, this transaction is more than a business decision, it represents a shared commitment to leverage the full potential of mRNA as a disruptive technology to develop transformative therapies with greater scale and speed,' said Dr. Alexander Zehnder, CEO of CureVac. 'For more than two decades, both companies have operated with related ambitions, often tackling challenges from different angles. This transaction aims at combining complementary scientific capabilities, proprietary technologies, and manufacturing expertise in the mRNA field under one roof.' BioNTech will start preparing an integration plan in alignment with BioNTech's ongoing group-wide transformation. Following the closing of the transaction, CureVac's operating subsidiary will become a wholly owned subsidiary of BioNTech. As part of this plan, BioNTech will integrate CureVac's state-of-the-art research and manufacturing site in Tübingen. BioNTech's all-stock acquisition of CureVac is expected to create long-term value for shareholders of both companies, building on BioNTech's proven track record in mRNA research, development, manufacturing, and commercialization, in particular the COVID-19 vaccine, which was developed in collaboration with Pfizer Inc. and marked the first approved mRNA product in the history of medicine. Based on BioNTech's strong financial position with €15.9 billion in cash, cash equivalents and security investments as of March 31, 2025, its global presence, late-stage clinical pipeline, and sustained investment in mRNA research across a broad range of solid tumor types, the acquisition positions the company to accelerate and broaden the development of mRNA-based medicines for patients in need. Following the closing of the exchange offer BioNTech and CureVac will effectuate a corporate reorganization of CureVac and its subsidiaries, resulting in BioNTech owning 100% of CureVac's business and interests in CureVac and its subsidiaries. As part of this corporate reorganization, CureVac shareholders who do not tender their shares in the exchange offer will receive the same consideration received for each CureVac share tendered in the exchange offer (without interest and subject to applicable withholding taxes). An extraordinary general meeting of CureVac's shareholders will be convened in connection with the exchange offer to adopt, among other things, certain resolutions relating to the transaction. The transaction was unanimously approved by both BioNTech's and CureVac's management and supervisory boards. The transaction, which is expected to close in 2025, is subject to the satisfaction of customary closing conditions, including a minimum acceptance threshold of at least 80% of CureVac's shares (which threshold may be reduced to 75% unilaterally by BioNTech under certain circumstances) and required regulatory approvals. Certain shareholders of CureVac representing 36.76% of CureVac's shares, including dievini Hopp BioTech holding GmbH & Co. KG and certain of its affiliates and all members of CureVac's management and supervisory boards, have entered into tender and support agreements, pursuant to which they have agreed, among other things, and subject to the terms and conditions of such agreements, to tender their shares in the exchange offer and to vote in favor of the resolutions relating to the transaction at the CureVac extraordinary general meeting to be held in connection with the transaction. In addition, the German Federal government has confirmed to generally have a positive view on the transaction. BioNTech therefore assumes that Kreditanstalt für Wiederaufbau – which holds 13.32% of the shares in CureVac on behalf of the Federal Republic of Germany – will support the transaction by tendering its shares in CureVac. As a result, BioNTech expects to have contractual commitments to support the transaction from shareholders of CureVac representing a total of 50.08% of CureVac shares towards the 80% minimum condition required under the exchange offer. Covington & Burling LLP, Hengeler Mueller Partnerschaft von Rechtsanwälten mbB and Loyens & Loeff N.V. served as legal counsel to BioNTech. Skadden, Arps, Slate, Meagher & Flom LLP and NautaDutilh N.V. served as legal counsel to CureVac. PJT Partners served as exclusive financial advisor to BioNTech. Goldman Sachs Bank Europe SE served as exclusive financial advisor to CureVac.

Editas Medicine Reports Proprietary Targeted Lipid Nanoparticle Delivery in Non-Human Primates Enables In Vivo HBG1/2 Promoter Editing for Sickle Cell Disease and Beta Thalassemia at the European Hematology Association 2025 Congress in June
Achieved 58% mean editing at five months after a single dose using high efficiency HSC delivery, demonstrating therapeutically relevant editing levels using a clinically validated strategy. Achievement supports development of a novel, in vivo approach to treating sickle cell disease and beta thalassemia. CAMBRIDGE, Mass., June 12, 2025 (GLOBE NEWSWIRE) — Editas Medicine, Inc. (Nasdaq: EDIT), a pioneering gene editing company, today shared new in vivo data demonstrating therapeutically relevant levels of HBG1/2 promoter editing in hematopoietic stem cells (HSCs) with a single dose of proprietary targeted lipid nanoparticle (tLNP) in non-human primates (NHPs). This clinically validated approach targeting HBG1/2 promoters to upregulate fetal hemoglobin (HbF) is in pre-clinical development as a potential transformative in vivo gene editing medicine for the treatment of sickle cell disease and beta thalassemia. The Company reported these data in a presentation available today and will detail the data in a poster session on Saturday, June 14th 6:30 – 7:30 p.m. CEST (12:30 – 1:30 p.m. EDT) at the European Hematology Association (EHA) 2025 Congress in Milan, Italy. In this study, the Company's proprietary tLNP formulation delivered HBG1/2 promoter editing cargo to HSCs in NHPs. Latest data from this ongoing NHP study showed that at five months a single intravenous administration of Editas' tLNP resulted in mean on-target editing levels in the HBG1/2 promoter region of 58% in HSCs: well exceeding the predicted editing threshold of ≥25% required for therapeutic benefit. In addition to achieving therapeutically relevant editing levels, the biodistribution data in NHPs with Editas' tLNP continue to show significant de-targeting of the liver in contrast to standard LNPs. 'These data from our in vivo HSC program confirm our ability to achieve high efficiency delivery, therapeutically relevant editing levels and favorable biodistribution in NHPs. These data validate the further development of Editas' proprietary HSC-tLNP for editing of the HBG1/2 promoters for the treatment of sickle cell disease and beta thalassemia,' said Linda C. Burkly, Ph.D., Executive Vice President and Chief Scientific Officer, Editas Medicine. Editas Medicine's in vivo HSC program targets HBG1/2 promoters to mimic naturally occurring mechanisms of hereditary persistence of fetal hemoglobin (HPFH) and utilizes proprietary AsCas12a to edit with high efficiency and minimize off-target editing. Editing the HBG1/2 promoters with AsCas12a with the investigational medicine reni-cel led to robust increases in HbF and total hemoglobin (Hb) in clinical trials. The presentation details are listed below. Abstracts can be accessed on the EHA website , and the presentation will be posted on the Editas Medicine website during the conference. Poster Presentation Details: Title: Targeted Lipid Nanoparticle Delivery in Non-Human Primates Enables In Vivo HBG1/2 Promoter Editing for β-hemoglobinopathies Date/Time: Saturday, June 14, 2025, 6:30 – 7:30 p.m. CEST/ 12:30 – 1:30 p.m. EDT Location: Allianz MiCo, Milano Convention Centre Session: Poster Session 2 About Editas Medicine As a pioneering gene editing company, Editas Medicine is focused on translating the power and potential of the CRISPR/Cas12a and CRISPR/Cas9 genome editing systems into a robust pipeline of in vivo medicines for people living with serious diseases around the world.
