Endocarditis

Nodenza Venture Partners invests in Trellis Bioscience Lead product TRL1068 targets biofilm, estimated to cause 60-70% of antibiotic resistant infections New York, October 22, 2024 – Nodenza Venture Partners (“Nodenza”), today announces its investment in Trellis Bioscience (“Trellis”), a clinical-stage company focused on discovering and developing native human monoclonal antibodies to treat and prevent drug-resistant, life-threatening infectious diseases. Trellis has developed a patented, proprietary technology (CellSpot) to clone genes of rare fully-human therapeutic monoclonal antibodies (mAbs) from memory B-cells of the blood of individual human donors. CellSpot has identified a high-affinity, broad-spectrum native human antibody, TRL1068, which targets and disrupts bacterial biofilm, a physiological factor promoting drug resistance in most clinically relevant multi-drug-resistant bacteria species, both gram positive and gram negative. TRL1068 is being developed for the treatment of chronic prosthetic joint infection (“PJI”), a chronic infection which requires, as standard of the care, the surgical removal of the prostheses with an estimated cost to the US health system of more than $10bn a year. In addition to PJI, it is estimated that biofilm is the cause of 60-70% of antibiotic resistant infections. TRL1068 has been granted Fast Track and QIDP designations and orphan drug designation for PJI and infective endocarditis by the U.S. Food and Drug Administration (FDA). Chronic PJI always forms biofilms on the prosthesis, thereby shielding the bacteria from eradication by antibiotics, being the reason for PJI to be a difficult-to-treat disease. As biofilm cannot be removed by antibiotics or any other non-invasive treatment, the current standard treatment of chronic PJI is a complex two-stage surgical procedure consisting of removal and replacement of the infected prosthesis. This costly and invasive two-stage process substantially and adversely affects quality of life, with increased immobility and morbidity in addition to decreased 5-year survival rates in patients with PJI when compared with non-infected patients that receive a prosthetic joint replacement. In a clinical proof-of-concept trial, published in a peer-reviewed article in the prestigious AAC Journal, TRL1068 has demonstrated the ability to disrupt the bacterial biofilm barrier to antibiotic access, allowing antibiotics to be efficacious without surgical intervention: In 25% of TRL1068-treated patients, biofilm was removed below the limit of detection after only 7 days of treatment, a finding that has never been observed in this patient population.64% of chronic PJI patients treated with an infusion of a single dose of TRL1068 and standard antibiotics had a bacterial biofilm burden below 100 CFU/mL sonication fluid after only 7 days of treatment. Although the sample size is small (n=11), a favourable comparison to historical data where only 15% of PJI patients are below that mark, suggesting that a treatment period 8 times longer, as planned in a Phase 2 study, will be highly efficacious.TRL1068 was well-tolerated across all three dose groups with no drug-related adverse events.The results of this initial exploratory study have provided strong evidence of efficacy across a diverse set of bacterial species, safety, and pharmacokinetic data to guide the design of a pivotal clinical study of TRL1068 for PJI with the goal to treat the infection without the need for a complex replacement surgery. Ross Morton, Managing Partner of Nodenza Venture Partners, said: “Antibiotic resistance is a significant and growing global threat, with insufficient investment to identify urgently needed new approaches. Trellis stands out with its truly novel and innovative approach to address antibiotic resistance. Through the application of its unique CellSpot technology, Trellis has the potential to be at the forefront of innovation in this critical field. CellSpot and TRL1068 align perfectly with Nodenza Venture Partners’ strategy of identifying and investing in disruptive technologies and therapies with the potential to deliver exceptional benefits to patients. We believe that Trellis has the potential to generate a multi-fold return on for Nodenza.” Stefan Ryser, Ph.D, President & CEO of Trellis Bioscience, commented: “Nodenza’s deep expertise of the pharmaceutical and biotech industry, and their recognition of the novelty of biofilm disruption, makes it an ideal investment partner for Trellis Bioscience as we prepare to advance TRL1068 rapidly through the clinic. The positive data generated to date give us confidence in the potential for a successful clinical study that may result in early FDA marketing authorisation given the five times higher mortality of the PJI standard of care surgery versus an aseptic prostheses replacement as well as the lack of new mechanisms to tackle the specific challenges of prosthetic joint infection. Nodenza has also recognized the enormous potential of TRL1068 beyond PJI as it addresses the broader global threat of antibiotic resistance.” Contacts: Nodenza Venture Partners Ross Morton, Managing Partnerinfo@nodenza.com Mo Advisory PRmo@mopradvisory.comMo Noonan / Jonathan Birt Notes to Editors About Nodenza Venture PartnersNodenza Venture Partners provides financial and operational support to early-stage and pre-commercial biotech and medtech companies and products designed to bring exceptional patient benefit.

With the IND (U.S.) and CTA (EU) about to be very shortly filed, the most important catalyst of our development strategy is in reach. In addition, clinical data from PhagoDAIR, our pilot study, are expected in late 2024, as planned.“ stated Thibaut du Fayet, Chief Executive Officer of PHAXIAM. BUSINESS HIGHLIGHTS Phage therapy strategy focused on high-value indications PHAXIAM has refocused its clinical development on programs targeting patients with severe resistant infections of high medical needs, associated with high mortality and budget impact. Significant progress has been achieved over the year 2024 to accelerate PHAXIAM’s strategy deployment on key therapeutic programs, particularly with its lead program targeting Prosthetic Joint Infections caused by Staphylococcus aureus (S. aureus). Clinical and regulatory strategy in S. aureus program on track With its lead S. aureus program, PHAXIAM pursues the ambition to propose a therapeutic solution to patients who failed traditional antimicrobial treatments in complex mono-bacterial S. aureus infections in several high-value indications. Prosthetic Joint Infections (PJI): toward the first global Phase II study, enabling a potential Early Access Pathway Leveraging on promising activity signals from real-life compassionate treatments, with more than 120 patients already treated (data to September 2024), PHAXIAM is preparing the initiation of the 1st global (EU/US) Phase II POC study (GLORIA) for PJI patients (Hip or Knee prosthesis) having an open-surgery debridement (DAIR) in combination with antibiotics. As planned, PHAXIAM aims to: deliver PhagoDAIR pilot study preliminary data at the end of 2024, and the study’s complementary data in 2025,accelerate the transitioning of PJI clinical development effort into the ambitious global Phase II proof-of-concept study (GLORIA) to be launched in Q1 2025. GLORIA is PHAXIAM’s most important asset, having the highest priority. This multicentric, randomized, comparative Phase II proof-of-concept study, is expected to enroll 100 patients in Europe and the US. PHAXIAM is about to file the Investigational New Drug Application (IND) and the Clinical Trial Application (CTA) to US and European regulatory agencies respectively. The formal approval of the study is expected in Q4 2024, in view of starting patient enrollment in Q1 2025. Upon a successful completion of GLORIA Phase II study anticipated in Q3 2026, PHAXIAM may be eligible to an Early Access Pathway, paving the way for a pre-commercialization in Europe as soon as H2 2027. Endocarditis Infections (EI): patients’ enrolment ongoing in five French sites This Phase I PK study enrolls patients with resistant S. aureus infections in the cardiac chambers and valves. First clinical results are now expected around mid-2025. If positive, these results could allow PHAXIAM to: accelerate a clinical development in this indication; and use the intravenous (IV) administration for other indications requiring this administration route. Clinical study in complex mono-bacterial Escherichia coli (E. coli) infections, validated and ready for enrolment The objective of this E. coli program, including a Phase I PK study validated by the French Health Authority (ANSM), is to propose a therapeutic solution to patients having failed traditional antimicrobial treatment in complex mono-bacterial E. coli infections in the urinary tract. Confirmed valuable real-life clinical benefit data from compassionate treatments with more patients coming from European countries To date, PHAXIAM has treated more than 120 patients under compassionate treatment status, most of them suffering from hip or knee PJI. The vast majority is located in France but more and more compassionate patients, stemming from other European countries, are treated in their country with PHAXIAM phages: Sweden, Switzerland, Latvia, Romania and United Kingdom. Data from the first 77 patients evaluated so far show promising results with infection control at 3 months (clinical endpoint) reaching approximately 80%, considered as a significant improvement over standard of care (SoC) in this hard-to-treat patient population with severe resistant infections, often undergoing 2nd or 3rd line SoC antibiotic treatment. Early 2025, PHAXIAM is planning to file for another AAC (Autorisation d’Accès Compassionnel – early access program), in order to bring a new compassionate treatment to PJI patients associated with Pseudomonas aeruginosa (P. aeruginosa) resistance, complementing the first obtained AAC, associated with S. aureus resistance. Complementary Investigator-sponsored trials (IST) In addition to PHAXIAM’s sponsored clinical studies, two other investigator-sponsored trials, in which PHAXIAM is highly involved, are the opportunity to deliver additional clinical POC data in other high-value indications: Phase II study (60 patients) in Diabetic Foot Ulcer (DFU): this clinical study, sponsored by Nîmes Hospital, targets DFU infections due to mono-bacterial S. aureus infection; this study is ready for First-Patient-In, expected before the end of this year.Phase II study (180 patients) in complex Respiratory Tract Infections (cUTI): this clinical study, sponsored by La Pitié Salpêtrière Hospital in Paris, targets nosocomial pulmonary infections due to P. aeruginosa, including patients with ventilator-associated pneumopathies (VAP), a growing concern in hospital environments. The filing of this study is planned in France (ANSM) in Q1 2025. H1 2024 FINANCIAL RESULTS Key financial figures for the first half of 2024 compared with the same period of the previous year aresummarized below. As a reminder, PHAXIAM’s consolidated financial statements in IFRS standards for H1 2023 include ex-Pherecydes financial results as of the date of the merger, i.e. June 23, 2023. Consequently, PHAXIAM’s P&L information for the first 6 months of 2023 are mostly related to ex-Erytech activities only, while PHAXIAM’s consolidated balance sheet as of June 30, 2023, includes the financial positions of both merged companies. The full Financial Statements of PHAXIAM Therapeutics as of June 30, 2024 has been filed with the AMF on Wednesday, September 25, 2024, and is available on the company’s website.

This decrease was driven by the 42% reduction of G&A expenses, including €3.4 million of non-recurring merger cost and €0.5 million of additional savings following Nasdaq delisting.This cost-cutting program was accelerated in the third quarter of 2024 to be in place as part of the 2025 budget. PHAXIAM’s operational R&D expenses in the first half of 2024 increased by €1.4 million (+41%) mostly on S. aureus development program, not included in the previous year's comparison. In addition, an impairment charge of €1.5 million on the endocarditis IP (EnDoCom) has been recorded. Net loss for the first half of 2024 was €10.6 million, compared with a net loss of €12.2 million for the same period of 2023. As of June 30, 2024, PHAXIAM had cash and cash equivalents totaling €1.5 million, compared with €10.5 million as of December 31, 2023. The €9 million decrease in cash position during the first half of 2024 was the result of a €8.2 million net cash utilization in operating activities including ~ €1 million in severance costs, €0.5 million in investing activities and €0.5 million used in financing activities, mostly related to lease reimbursement. On July 1, 2024, with the settlement & delivery of the €7.8 million capital increase, PHAXIAM's cash position increased by a net €6.8 million, after payment of capital increase costs. The Company believes that its current cash position can fund its existing programs and expected operating expenses into March 2025. The Company is studying all options to extend its financial visibility: cost reduction program, obtaining non-dilutive financing at the national and European level, search for strategic and institutional investors, etc. MANAGEMENT TEAM EVOLUTION Eric Soyer, former CFO / COO, is leaving PHAXIAM to pursue other interests. Frédéric Mathat succeeds him and will lead the Company’s Finance department as CFO.After a first robust experience in accounting and consolidation of listed companies (8 years at Nexity, the real estate branch of Vivendi, then 7 years at Sequana), Frédéric had been financial director of the Canson group for 11 years. He joined the pharmaceutical industry in 2017 to lead Erytech's finance department alongside Eric Soyer, until the merger with Pherecydes, in which he was instrumental and committed all along the process that led to the creation of PHAXIAM. Thibaut du Fayet, Chief Executive Officer of PHAXIAM, commented: “I would like to warmly thank Eric Soyer for his dedication during these 8 years spent at Erytech where he performed several fundraisings on Nasdaq and Euronext public markets, then at PHAXIAM where he was very instrumental in the success of the merger, as his contribution has been essential in designing PHAXIAM’s strategy; I wish him all the best for the near future. I am also delighted to welcome Frédéric as Chief Finance Officer. His extensive expertise and proven track record in finance add great value to our team.” KEY NEWSFLOW AND MILESTONES EXPECTED OVER THE NEXT 12 MONTHS Phase II IST in Diabetic Foot Ulcer (DFU) First-Patient-In expected in Q4 2024PhagoDAIR pilot study clinical readout expected before end of year 2024GLORIA global Phase II IND and CTA validation expected in Q4 2024GLORIA global Phase II First-Patient-In expected in Q1 2025Endocarditis Phase I PK study first readout expected around mid-2025 FIRST HALF 2024 WEBINAR DETAILS PHAXIAM management will hold a webinar today, Wednesday, September 25, 2024, at 6:00 pm CEST on the business highlights and financial results for the first half of 2024.
