Herpes Simplex

ReOpen was the first ever large placebo-controlled clinical trial program to demonstrate statistically significant reduction of symptoms in chronic sinusitis patients without nasal polyps Clinical trial program also showed reduction in sinus inflammation and in acute exacerbations, which frequently result in use of antibiotics XHANCE uses the proprietary Exhalation Delivery System to enable deposition of a proven steroid in target areas of inflammation deep in the nose not typically reached by standard nasal sprays Chronic sinusitis affects approximately 30 million adults in the U.S. YARDLEY, Pa., March 15, 2024 (GLOBE NEWSWIRE) -- Optinose (NASDAQ:OPTN), a pharmaceutical company focused on patients treated by ear, nose and throat (ENT) and allergy specialists, today announced the U.S. Food and Drug Administration (FDA) has approved XHANCE® (fluticasone propionate) nasal spray for the treatment of chronic rhinosinusitis without nasal polyps in patients 18 years of age and older. Chronic sinusitis (also called “chronic rhinosinusitis” or “CRS”) is one of the most common chronic diseases, affecting approximately 30 million adults in the United States. Research shows that the disease impairs quality of life to a similar degree as other serious chronic conditions, such as chronic obstructive pulmonary disease, sciatica, or migraine. Chronic sinusitis is also one of the most common diagnoses in adult outpatient medicine. Chronic sinusitis is diagnosed in approximately 10 million outpatient visits, of which approximately 70% result in antibiotic prescriptions, and leads to more than 600,000 surgeries annually. Although there are FDA–approved medications to treat nasal polyps, including XHANCE, no medication had ever been approved for the more than two-thirds of chronic sinusitis patients who do not have nasal polyps – until today.1 “The FDA approval of XHANCE for the treatment of CRS without nasal polyps is an important milestone,” said Rick Chandra, M.D., Professor of Otolaryngology-Head and Neck Surgery, Endowed Director, Roland “Ron” Eavey, MD, SM Endowed Directorship in Leadership and Education, Service Chief, Rhinology and Skull Base Surgery, Vanderbilt University. “Until today, we have been forced to use unproven therapies to try and alleviate the symptoms that these patients suffer. While we often resort to using nasal steroid sprays in this patient population, they have never been shown to be effective in large placebo-controlled clinical studies. XHANCE, which uses the Exhalation Delivery System to enable delivery of an established topical steroid to the areas of the nasal cavity and sinuses we know to be extensively inflamed, is now proven to be effective in treating our CRS patients both with and without nasal polyps.” “People who don’t suffer from chronic sinusitis may not appreciate how burdensome the condition can be. More than 80% of patients with chronic sinusitis report frustration with symptom relief when using a standard-delivery nasal steroid sprays, and patients commonly use multiple unproven over the counter medications in an effort to find symptom relief.” said Ramy Mahmoud, MD, MPH, CEO of Optinose. “Although chronic sinusitis is one of the most common diagnoses in outpatient physician visits, and surgery is available, there has never been a prescription medication approved by the FDA as safe and effective to treat the millions of patients without nasal polyps suffering from this debilitating disease. We are thrilled to now be able to offer new hope to these patients and believe XHANCE has the potential to become part of the standard of care for the treatment of chronic sinusitis.” The approval was based on data from the ReOpen program evaluating XHANCE for treatment of adults with chronic sinusitis. A drug-device combination product, XHANCE uniquely combines a widely used nasal steroid with the Exhalation Delivery System™, an innovative delivery system designed to target the sites where inflammation occurs, especially difficult-to-access sinuses and sinonasal drainage tracts not typically reached by standard-delivery nasal sprays. The safety pro tolerability of XHANCE for patients in the ReOpen trials was generally consistent with its currently labeled safety profile. The most common adverse reactions (incidence ≥ 3%) in the ReOpen program were epistaxis, headache, and nasopharyngitis.

About XHANCE XHANCE® is a drug-device combination product that uses the Exhalation Delivery System™ (also referred to as the EDS®) designed to deliver a topical steroid to the high and deep regions of the nasal cavity where sinuses ventilate and drain. XHANCE is approved by the U.S. Food and Drug Administration for the treatment of chronic rhinosinusitis (with and without nasal polyps) in patients 18 years of age or older. About the ReOpen Program The ReOpen program comprised two global, randomized, double-blind, placebo-controlled Phase 3 trials that evaluated the efficacy and safety of one or two sprays of XHANCE in each nostril twice daily, over 24 weeks, in patients suffering from chronic sinusitis. In ReOpen1, the first of the two trials, 332 chronic sinusitis patients either with or without concurrent nasal polyps were treated. In ReOpen2, 222 chronic sinusitis patients who did not have polyps in the nasal cavity were treated. The co-primary endpoints were change from baseline in symptoms, as measured by composite symptom score (nasal congestion, facial pain or pressure, and nasal discharge) at the end of week 4, and change in inflammation inside the sinus cavities, as measured by CT scans (change in the average of the percentages of volume occupied by disease in the ethmoid and maxillary sinuses) at week 24. The ReOpen trial program is a landmark research program that included the first ever large, placebo-controlled trials we are aware of to demonstrate that any nasal medication produces significant improvement in both symptoms and inflammation inside the sinuses for patients with chronic sinusitis, regardless of whether or not nasal polyps are present, and to show reduction in the number of acute exacerbations.1 IMPORTANT SAFETY INFORMATION CONTRAINDICATIONS: Hypersensitivity to any ingredient in XHANCE. WARNINGS AND PRECAUTIONS: Local nasal adverse reactions, including epistaxis, erosion, ulceration, septal perforation, Candida albicans infection, and impaired wound healing, can occur. Monitor patients periodically for signs of possible changes on the nasal mucosa. Avoid use in patients with recent nasal ulcerations, nasal surgery, or nasal trauma until healing has occurred. Glaucoma and cataracts may occur with long-term use. Consider referral to an ophthalmologist in patients who develop ocular symptoms or use XHANCE long-term. Hypersensitivity reactions (e.g., anaphylaxis, angioedema, urticaria, contact dermatitis, rash, hypotension, and bronchospasm) have been reported after administration of fluticasone propionate. Discontinue XHANCE if such reactions occur. Immunosuppression and infections can occur, including potential increased susceptibility to or worsening of infections (e.g., existing tuberculosis; fungal, bacterial, viral, or parasitic infection; ocular herpes simplex). Use with caution in patients with these infections. More serious or even fatal course of chickenpox or measles can occur in susceptible patients. Hypercorticism and adrenal suppression may occur with very high dosages or at the regular dosage in susceptible individuals. If such changes occur, discontinue XHANCE slowly. Assess for decrease in bone mineral density initially and periodically thereafter. ADVERSE REACTIONS: Chronic rhinosinusitis without nasal polyps: The most common adverse reactions (incidence ≥3%) are epistaxis, headache, and nasopharyngitis. Chronic rhinosinusitis with nasal polyps: The most common adverse reactions (incidence ≥3%) are epistaxis, nasal septal ulceration, nasopharyngitis, nasal mucosal erythema, nasal mucosal ulcerations, nasal congestion, acute sinusitis, nasal septal erythema, headache, and pharyngitis. DRUG INTERACTIONS: Strong cytochrome P450 3A4 inhibitors (e.g., ritonavir, ketoconazole): Use not recommended. May increase risk of systemic corticosteroid effects. USE IN SPECIFIC POPULATIONS: Hepatic impairment. Monitor patients for signs of increased drug exposure. Please see full Prescribing Information, including Instructions for Use References James N.

Stijn Van Rompay, Chief Executive Officer of Hyloris, commented: “Despite a challenging year for the global healthcare industry, 2023 proved to be a year of significant accomplishment for Hyloris. As a company built on the unique and successful strategy of repurposing and reformulating existing pharmaceuticals, we achieved a major milestone with the U.S. approval of Maxigesic® IV in partnership with AFT Pharmaceuticals, marking a crucial step in delivering this innovative pain management solution to American patients. Additionally, approval was secured for Podofilox gel, the first generic version of Condylox® Gel, expanding access to this medication. Our unwavering commitment to research and development yielded impressive progress across our diverse product pipeline. These advancements solidify our position as a leader in providing solutions to unmet medical needs in the years to come. We are incredibly proud of our team's dedication and resilience throughout this transformative year. Looking ahead to 2024, Hyloris is poised for continued growth and innovation. We plan to significantly bolster our pipeline with the addition of several new product candidates addressing critical unmet medical needs. Recent additions, including treatments for Vulvar Lichen Sclerosus and Burning Mouth Syndrome, demonstrate our commitment to expanding our portfolio and addressing a wider range of patient needs. We remain confident in our ability to continue delivering value to patients, shareholders, and all stakeholders and expect continued growth beyond 2024. Commercial Highlights Maxigesic® IV is a patented, unique combination, intravenous formulation for the treatment of post-operative pain and is currently licensed to partners covering over 100 countries across the globe. During 2023 and early 2024: A marketing authorization was granted by the United States Food and Drug Administration (FDA) in October 2023.Hikma Pharmaceuticals (Hikma), a leading supplier of complex injectable hospital products, has launched the product in the U.S. under the tradename Combogesic® IV. An exclusive license and distribution agreement had previously been signed between Hyloris’ partner AFT Pharmaceuticals (AFT) and Hikma.Additional submissions for marketing authorization were made in 13 countries in the Middle East, Africa, Latin America, and Asia.Additional marketing authorizations have been granted in 8 countries including Poland, South Africa, and Spain. In early 2024, Health Canada granted approval bringing the total number of approvals to 50.Launches occurred in 14 countries including Norway, Singapore, Belgium, The Netherlands, the Czech Republic, and Romania. Imminent launches are expected in several additional countries, bringing the total number of countries where Maxigesic® IV will be available up to more than 30. In the United States, chronic opioid usage in patients following surgery averages around 9%, ranging from 4% to 24% among various specialties. Drug overdoses involving opioids resulted in over 80.000 deaths in the U.S. in 2021. Patients who experienced an opioid overdose accounted for nearly $2 billion in annual hospital costs. Sotalol IV is a patented, intravenous formulation of Sotalol for the treatment of atrial fibrillation, and life-threatening ventricular arrhythmias developed for the U.S. Sotalol IV potentially allows to significantly reduce the length of hospital stay and the overall cost of care and potentially improve patient outcomes. Hyloris is taking further steps targeting to increase product related revenues in the future (see also: Ongoing Legal Proceedings). Podofilox Gel (Product previously referenced as HY-016) In December 2023, our partner Padagis US LLC (Padagis) received marketing authorization for Podofilox gel 0.5% from the FDA. Padagis launched the product in December 2023. It is the first generic for Condylox® Gel in the U.S. Podofilox Gel is an antimycotic drug for the topical treatment of external genital and perianal warts caused by certain types of the Human Papilloma Virus (HPV). Around 1% of the sexually active population in the U.S. presents with genital or perianal warts.1 To date there is a vaccine for HPV but no cure. For the 12 months period ending December 2022, Condylox® Gel had U.S. sales of approximately $9 million according to IQVIA Health. Other Commercial Highlights Tranexamic Acid RTU Additional out-licensing agreements were signed for Tranexamic Acid RTU in 2023. These agreements cover a large European country and several major Asian countries, with a combined population of over 60 million people. Previous agreements have been signed in 2021 for Australia, New-Zealand and Canada. In 2023, our licensing partner for Canada submitted an application for approval by Health Canada. Additional regulatory submissions in the partnered territories are in progress, and more out-licensing agreements are expected going forward. An Abbreviated New Drug Application (ANDA) has been submitted to the U.S. FDA. Tranexamic acid injection is an established antifibrinolytic agent used in emergency situations with major hemorrhages and is also used as a prophylactic agent in surgeries. Hyloris is developing a ready-to-use (RTU) formulation for infusion. Atomoxetine Oral Liquid An out-licensing agreement was signed with Kye Pharmaceuticals (Kye) in October 2023. Kye will exclusively commercialize the product in Canada where atomoxetine is currently not available as an oral liquid formulation. The introduction of an oral liquid formulation in the ADHD (Attention Deficit Hyperactivity Disorder) medication category has historically led to significant market share gains2. This suggests a strong potential for Atomoxetine Oral Liquid in Canada, where an estimated 1.8 million people (or 4-6% of adults and 5-7% of children) are diagnosed with ADHD3. ADHD is a chronic condition, with symptoms persisting into adulthood for 60-80% of patients4. Under the terms of the agreement, Hyloris will be eligible to receive attractive sales-related milestone payments (totaling up to USD 7.5 million), and a substantial share of the generated revenue. New Pipeline Product Candidates Our business development team leverages its expertise in existing products, real-world data, and a vast network to identify unmet medical needs. This includes collaborating with healthcare professionals, patient groups, insurers (payors), and industry partners. In 2023 over 87 opportunities were screened and 3 product candidates will meet our investment criteria of €7 million5 in 7 years or less. For product candidates which Hyloris intends to out-license, the strategic goal is to capture a substantial part of the net product margin realized by our commercial partners. Hyloris aims to achieve this by partnering these assets close to regulatory submission, except in countries where additional local clinical trials are required. In general, we will prioritize in-market product sales or profit-based participation over (upfront) milestone payments. We aim to increase our product portfolio to 30 assets by 2025, with a focus on accelerating pipeline growth in the near future. HY-091, a novel topical treatment candidate for Vulvar Lichen Sclerosus (VLS) was announced in January 2024. VLS is a chronic inflammatory condition affecting an estimated 3% of women, causing severe pain, itching, and discomfort, significantly impacting their quality of life. HY-091 is being developed as a convenient and user-friendly treatment specifically designed to target these VLS symptoms. Hyloris has partnered with AFT for co-development, registration, and worldwide commercialization. HY-090, a promising new treatment candidate for Burning Mouth Syndrome (BMS) was announced in December 2023. BMS is a chronic condition affecting millions, primarily postmenopausal women, causing a burning, tingling, or scalding sensation in the mouth for months at a time. While the mouth appears healthy, sufferers may also experience dry mouth or taste alterations, the exact cause of BMS remains unknown. Studies suggest that 0.7% to 5% of individuals in the U.S. might be affected6. Hyloris has partnered with AFT to co-develop and commercialize the product worldwide. HY-088 was announced in January 2023. This novel, proprietary oral formulation will be administered to patients with hypophosphatemia – a condition where the blood level of phosphorus is lower than 2.5mg/dL. Patients can develop hypophosphatemia from either a genetic abnormality (such as Cushing Syndrome or osteomalacia) or an acquired condition (like long-term use of diuretics or phosphate binders). It is estimated hypophosphatemia affects around 5% of hospitalized patients, and a subpopulation needs direct treatment during and/or after their hospital stay. Treatment protocols for patients deficient in phosphate are well-established and have proven useful in other situations of bone mineral imbalance. Oral administration is the preferred way of treating hypophosphatemia, although in most countries no approved drugs exist. Currently, physicians mostly rely on compounded drugs which have, by definition, not been submitted for regulatory scrutiny regarding safety, efficacy, and quality. R&D Update Throughout 2023, Hyloris achieved significant advancements across the entire R&D portfolio, propelling the 18 product candidates and 3 high-barrier generics closer to commercialization. Key milestones were met for multiple programs, and discussions with regulatory agencies and partners are underway to solidify development plans. As a result, Hyloris anticipates submitting multiple INDs (Investigational New Drug applications) and NDAs (New Drug Applications) throughout 2024 and early 2025. Enhanced Capabilities Drive Efficiency Further bolstering our R&D efforts, Hyloris officially opened its new and improved R&D lab at the Montlegia Science Park in June 2023. This on-site facility allows Hyloris to perform drug formulation and analytical activities in-house, streamlining processes and optimizing resource allocation for the expanding pipeline. Cardiovascular Portfolio Hyloris is actively engaged in advancing a comprehensive portfolio dedicated to addressing a wide range of conditions within the largest global treatment category – cardiovascular care. These products are currently progressing through or towards clinical trials, with the aim of significantly enhancing the quality of life for patients. Main highlights for 2023 and selected expected milestones for 2024 include: Aspirin IV: Registration batches have been manufactured and the stability study is ongoing. An NDA submission is planned for the U.S. as soon as all necessary data has been collected. Aspirin IV is an intravenous (IV) formulation of acetylsalicylic acid (ASA) to be used in an emergency setting. Aspirin is not available in the U.S. as an IV product. Currently, most patients suspected of having an emergency cardiovascular event (such as a myocardial infarction or stroke) are immediately given oral aspirin to decrease their risk of morbidity and mortality. Milrinone: The optimization of the extended-release formulation for alcohol resistance marked a significant development milestone. Preparations for a pilot pharmacokinetic (PK) study are in progress. Oral milrinone is being developed as a novel, extended-release formulation offering convenient oral dosing for a selected population of end-stage heart failure (HF) patients who have Left Ventricular Assist Devices (LVADs). HY-074: All non-clinical studies were completed in 2023. A patent application was filed through the Patent Cooperation Treaty (PCT) which allows an applicant to seek patent protection in several different countries – including the U.S. Hyloris is targeting an IND submission for Q2 2024 for the PK bridging study expected to start at the end of 2024. HY-074 is an intravenous formulation of current standard of care treatment for acute coronary syndrome (ACS) to offer faster onset of action, more convenient administration, and dosage control. It is currently available in oral form, which should allow for an optimal switching strategy from the oral form to an IV in a hospital setting. Dofetilide IV: Registration batches have been manufactured and the stability study is ongoing. A CRO has been selected for the required clinical study. An NDA submission is planned for the U.S. as soon as all necessary data has been collected. A pivotal clinical study to support regulatory submission for Dofetilide IV is nearing completion, with results expected by Q3 2024. Additional U.S. patent applications have been filed to bolster the drug's intellectual property protection. Other Value-Added Programs Hyloris, in collaboration with its development partners, is achieving consistent progress on all stages of our value-added programs. Main highlights for 2023 and expected milestones for 2024 include: Tranexamic Acid Oral Mouth Rinse (previously HY-004): A Type A meeting with the FDA resulted in alignment on the phase 3 study protocol. The phase 3 trial began in November 2023, enrolling the first patient in early 2024. Completion of enrollment (Last Patient Last Visit - LPLV) is expected by year-end, with study results anticipated in the first half of 2025. This rinse targets patients on blood thinners (anticoagulant therapies) undergoing dental procedures with a high risk of excessive bleeding. Additionally, Hyloris intends to explore the effectiveness in a wider range of related oral surgery procedures, encompassing both patients with and without bleeding disorders who could benefit from a localized treatment to reduce blood clotting. Miconazole/Domiphen Bromide: Hyloris is co-developing Miconazole/Domiphen Bromide (MCZ/DB) with Purna Female Healthcare, a topical cream combining miconazole and domiphen bromide. This innovative treatment targets Recurrent Vulvovaginal Candidiasis (rVVC), a chronic and often debilitating vaginal yeast infection affecting nearly 1 in 10 women throughout their lives. The Phase 2 clinical trial, completed in late 2023 (Q4), showed promising results. The low-dose group exhibited evidence of delayed disease recurrence at day 29. These findings will be used to design the next clinical trial, scheduled to begin by year-end 2024. MCZ/DB presents a strong scientific and commercial potential for addressing rVVC. AlenuraTM: Hyloris is co-developing Alenura™ with Vaneltix. It is a first-in-class drug candidate designed to bring immediate pain relief to patients suffering from interstitial cystitis/bladder pain syndrome (IC/BPS). This chronic condition affects at least 6 million people in the U.S. alone. Alenura™ stands out for its innovative dual mode-of-action. It combines a new, alkalinized form of lidocaine for fast pain relief with heparin to potentially aid in the regeneration of the bladder lining. This unique approach holds promise for providing both immediate symptom relief and long-term benefits for IC/BPS patients. June 2023 marked a significant milestone with the enrollment of the first patient in the Phase 2 clinical trial of Alenura™. This pivotal study will compare the effectiveness of Alenura™ against its individual components (lidocaine and heparin) as well as a placebo. PTX-252: PTX-252 is a novel chelating agent in development for the treatment of Acute Myeloid Leukemia (AML). This product candidate incorporates a novel molecular entity that is a derivative of a known established molecule. This advancement was followed by positive news: Hyloris' co-development partner, Pleco, secured Orphan Drug Designation from the FDA for PTX-252 specifically for AML. PTX-252's potential lies in its ability to potentially improve the effectiveness of existing chemotherapy for AML patients. This is particularly significant as AML affects approximately 160,000 people globally. Previous research suggests a correlation between high levels of toxic metals and lower survival rates in AML patients. A Pre-Investigational New Drug (PIND) meeting with the FDA is planned. Valacyclovir: A successful study demonstrating bioequivalence was completed in 2023. An additional pivotal study can be expected to start and close in H1 of 2024. Registration batches have been manufactured to demonstrate pharmaceutical quality of the product and robustness of the manufacturing process. Hyloris is developing a liquid formulation of valacyclovir which is currently only available in oral solid form. Valayclovir is an antiviral drug commonly used to treat the Herpes Simplex Viruses (HSV) that cause cold sores, genital herpes, chicken pox, and shingles. Management & Board changes The total headcount of the Company grew to 42 people, with several key recruitments occurring over the summer. To enhance the development activities, only limited additional hiring is required. Both the C-level executives and all board members remained in their respective positions, providing continuity in the company's leadership. Business Outlook With 18 reformulated and repurposed molecules, and 3 high-barrier generics, several clinical trials are expected to start and/or finish within 2024. The Company is actively accelerating the growth of its product pipeline, aiming to reach 30 product candidates by 2025. The company is expecting several clinical and regulatory achievements in the next 15 months. Several clinical studies will be initiated or completed. The Company is anticipating multiple NDA submissions to the U.S. FDA and other regulatory agencies. Webcast Details The Company will host a webcast conducted in English to present its 2023 annual results and 2024 Business Outlook, followed by a live Q&A session.

Total Revenue and Other Income In 2023, total revenue and other income increased to €4,406 thousand compared to €2,386 thousand in 2022, which is 85% higher compared to last year. The strong growth is mainly driven by increase of royalties of the 3 early-stage commercialized products, services provided to external partners and non-dilutive funding which we received from a US State Government and the Walloon region in Belgium. Results The Company realized a net loss of €15,762 thousand in 2023, compared to a net loss of €11,770 thousand last year. The net loss is mainly resulting from the increase in R&D expenditure and G&A expenses for supporting the development of the Company. R&D expenditure during 2023 amounted to €14,749 thousand, compared to €10,272 thousand in 2022. The increase was mainly driven by the progressive shift from early to late-stage development of several product candidates as well as the increased headcount of the research and development team leading to additional costs. General and administrative expenses increased to €5,653 thousand in 2023 versus €3,517 thousand in 2022, mainly driven by higher legal costs related to the AltaThera’s litigation compared to last year. The net financial income in 2023 was €474 thousand compared to a net financial loss of €127 thousand in 2022. The positive evolution of the financial result is mainly due to the impact of an active cash management strategy in a context of high short term interest rates both in EURO and USD. As a result, net losses in 2023 increased to €15,762 thousand versus €11,770 thousand in the same period of 2022. Balance Sheet The Company’s non-current assets mainly consist of (1) investments in joint ventures of € 3,801 thousand, (2) intangible assets of €3,828 thousand including capitalized development, purchased assets and in-licensing costs, versus €3,600 thousand in 2022, (3) Right of use assets related to the leasing of the office, lab and cars, (4) shares in Pleco of €1,000 thousand, (5) a prepayment of future royalties to a third party of $700 thousand and (6) a tax credit. Hyloris does not capitalize research and development expenses until the filing for a marketing authorization for the applicable product candidate. Research and development expenditures incurred during the period were accounted for as operating expenses. When an intangible asset is acquired and capitalized, the amortization begins when the asset is available for commercialization. The Company’s current assets mainly consist of €30,196 thousand in cash and cash equivalents on total assets of €47.61 million, and trade and other receivables of €4.1 million. The increase in Right-of-use assets and borrowings is due to the start of the lease for the new lab. The Company received an advance payment related to a government grant from the Walloon region. €43 thousand of this advance is a financial liability and €37 thousand is part of Trade and other liabilities. Cash Position and cash flow The Company maintains its strong cash position, with a current cash and cash equivalents totaled €30,196 thousand at the end of 2023, compared to €43,457 thousand at the end of 2022 (which includes a deposit for an amount of €10 million which has been reclassified to Other investment in 2022). Net cash outflow generated from operating activities was €12,726 thousand in 2023, compared to a net operating cash outflow of €12,499 thousand in 2022. The stable net operating cash outflow is attributed to an internal control system implemented to oversee expenditure and cash flow, which includes effective management of working capital.

EQUIVALENTS at end of year, calculated30,19633,457* RESTATEMENT OF THE YEAR 2022 and HALF-YEAR 2023 Accounting treatment of the transactions with Qliniq Hyloris initially recognized (a) €1 million in revenue in 2022 from the divestment of HY-038, and (b) € 1 million in R&D expenses and € 0,2 million in intangible assets in H1 2023 for the purchase of HY-088. A reassessment determined that both transactions qualify as a non-monetary exchange because negotiations and valuations occurred simultaneously. Due to the development stage of the products exchanged, the fair value of neither the asset received, nor the asset given up can be reliably determined. As a result of this reassessment, the restated financials for 2022 will reverse the €1 million revenue from the divestment of HY-038. This adjustment will also affect the half-year 2023 financial statements, resulting in a reversal of €1 million in R&D expenses for HY-088. These expenses are offset against the €1 million received by Hyloris for HY-038. (See Press Release dated 14th of March 2024 on the restatement for more information) The following tables summarize the impact of the restatement on the consolidated financial statements.

There is no impact on the consolidated statement of cash flows for the year ended per December 31, 2022, as no cash inflow occurred yet. Audit Report The statutory auditor, KPMG Bedrijfsrevisoren - Réviseurs d’Entreprises, represented by Olivier Declercq, has informed us that the audit procedures were not yet completed. ONGOING LEGAL PROCEEDINGS In August 2022, AltaThera Pharmaceuticals LLC filed a complaint before the District Court for the Northern District of Illinois against Academic Pharmaceuticals Inc, Dr. Somberg and Hyloris Pharmaceuticals, for (a.o.) alleged misappropriation of AltaThera’s trade secrets and confidential information, improper inventorship, and breach of contract, which seeks (punitive) damages and termination of the agreement whereby Hyloris licenses Sotalol IV to AltaThera (the “Litigation”). Hyloris moved to dismiss the complaint for improper service of process and lack of jurisdiction. Further, in November 2022, Hyloris initiated an arbitration against AltaThera for breach of the same licensing agreement between Hyloris and AltaThera in relation to Sotalol IV, including the failure of AltaThera to use commercially reasonable efforts in selling Sotalol IV as required under the licensing agreement, which seeks damages and termination of the licensing agreement (the “Arbitration”). AltaThera responded and counter-demanded, reasserting its claims from the Litigation. At the end of August 2023, all parties agreed to stipulate to the dismissal of the Litigation and to consolidate the Litigation and the Arbitration before the American Arbitration Association (“AAA”) in New York. Hyloris contests the claims asserted by AltaThera and, based upon Hyloris’ assessment of the documents and expert reports put forward to date by AltaThera to support its claims, Hyloris is of the view that there is no convincing evidence supporting AltaThera’s claims for liability or damages. On the other hand, Hyloris believes strongly in the merits of its claims against AltaThera, and that its position is well supported by its expert reports and other documents and evidence submitted to the arbitration panel. Arbitration hearings are scheduled in April 2024 with a final decision expected by the end of H1 2024. Hyloris remains fully confident about the outcome of this litigation in its favor. Hyloris however cannot guarantee that the outcome of the litigation, even if in its favor, may not have a negative impact on future sales of Sotalol IV. About Hyloris Pharmaceuticals SA Hyloris is a specialty biopharma company focused on innovating, reinventing, and optimizing existing medications to address important healthcare needs and deliver relevant improvements for patients, healthcare professionals and payors.

Submission is supported by data from the Phase 3 QUASAR program, which showed a significantly greater percentage of patients with moderately to severely active ulcerative colitis who received TREMFYA® achieved clinical remission at Week 44 compared with placebo SPRING HOUSE, Pa., March 11, 2024 /PRNewswire/ -- Johnson & Johnson today announced the submission of a supplemental Biologics License Application (sBLA) to the U.S. Food and Drug Administration (FDA) seeking approval of TREMFYA® (guselkumab) for treatment of adults with moderately to severely active ulcerative colitis (UC). The submission is based on results from the Phase 3 QUASAR program evaluating the efficacy and safety of TREMFYA® in the treatment of individuals living with moderately to severely active UC who had an inadequate response or intolerance to conventional therapy, prior biologics and/or JAK inhibitors.1 The data show statistically significant and clinically meaningful improvements in symptoms, patient-reported outcomes such as fatigue and measures of disease activity including high bar endpoints such as endoscopic and histologic remission.2,3 The safety results were consistent with the known safety profile of TREMFYA® in approved indications.2,3,a "Despite advances in therapy, many people living with ulcerative colitis still experience inadequate response to or do not tolerate existing therapies," said David Lee, MD, PhD, Global Therapeutic Area Head Immunology. "TREMFYA has the potential to be a new treatment option for patients. We look forward to working with the FDA in review of this application and remain focused on developing new therapies for those living with chronic autoimmune conditions, such as ulcerative colitis, who are experiencing persistent and debilitating symptoms." TREMFYA® is a dual-acting IL-23i that blocks IL-23 and binds to CD64, a receptor on cells that produce IL-23.4 IL-23 is a cytokine secreted by activated monocyte/macrophages and dendritic cells that is known to be a driver of immune-mediated diseases including UC.5 TREMFYA® was first approved in the U.S. in July 2017 for the treatment of adult patients with moderate-to-severe plaque psoriasis and was subsequently also approved for adults with active psoriatic arthritis in July, 2020.4 Clinical data from the Phase 3 QUASAR induction study through 12 weeks were presented at the 2023 Digestive Disease Week (DDW) Annual Meeting2 and results from the Phase 3 QUASAR maintenance study through 44 weeks will be presented at an upcoming medical meeting. Editor's Notes: a. TREMFYA® is not approved to treat UC. ABOUT THE QUASAR STUDY ( NCT04033445 ) QUASAR is a randomized, double-blind, placebo-controlled, parallel group, multicenter, seamless Phase 2b/3 program designed to evaluate the efficacy and safety of TREMFYA®, a selective IL-23 inhibitor, in adult patients with moderately to severely active ulcerative colitis who had an inadequate response or intolerance to conventional therapy (e.g., thiopurines or corticosteroids), prior biologics and/or JAK inhibitors (i.e., tumor necrosis factor-alpha antagonists, vedolizumab, or tofacitinib).1 QUASAR included a Phase 2b dose-ranging induction study, a confirmatory Phase 3 induction study, and a Phase 3 maintenance study. Efficacy, safety, pharmacokinetics, immunogenicity, and biomarkers are assessed at specified time points.1 ABOUT ULCERATIVE COLITIS Ulcerative colitis (UC) is a chronic disease of the large intestine, also known as the colon, in which the lining of the colon becomes inflamed and develops tiny open sores, or ulcers, that produce pus and mucus.6 It is the result of the immune system's overactive response.6 Symptoms vary, but may include loose and more urgent bowel movements, rectal bleeding or bloody stool, persistent diarrhea, abdominal pain, loss of appetite, weight loss and fatigue.6 ABOUT TREMFYA® (guselkumab) Developed by Johnson & Johnson, TREMFYA® is the first approved fully-human, dual-acting monoclonal antibody that blocks IL-23 by binding to the p19 subunit of IL-23 and binding to CD64, a receptor on cells that produce IL-23.4 IL-23 is an important driver of the pathogenesis of inflammatory diseases.5 Findings for dual acting are limited to in vitro studies that demonstrate guselkumab binds to CD64, which is expressed on the surface of IL-23 producing cells in an inflammatory monocyte model. The clinical significance of this finding is not known.7,8,9,10 TREMFYA® is approved in the U.S.,4 Canada,11 Japan12 and a number of other countries for the treatment of adults with moderate to severe plaque psoriasis (PsO) who are candidates for injections or pills (systemic therapy) or phototherapy (treatment using ultraviolet light) and for the treatment of adult patients with active psoriatic arthritis ( PsA).4 It is also approved in the EU for the treatment of moderate to severe plaque PsO in adults who are candidates for systemic therapy and for the treatment of active PsA in adult patients who have had an inadequate response or who have been intolerant to a prior disease-modifying antirheumatic drug therapy.13 Johnson & Johnson maintains exclusive worldwide marketing rights to TREMFYA®.
