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.

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.

AGAMREE® (vamorolone) a Novel Alternative Corticosteroid with Demonstrated Properties in Maintaining Efficacy and a Well-Tolerated Side Effect Pro > Available in the U.S. by Prescription for Patients Aged Two Years and Older Catalyst Pathways® Program will Support AGAMREE Patients and Available to Help Ensure DMD Patients Affordable Access and Product Education CORAL GABLES, Fla., March 13, 2024 (GLOBE NEWSWIRE) -- Catalyst Pharmaceuticals, Inc. ("Catalyst") (Nasdaq: CPRX), a commercial-stage biopharmaceutical company, today announced the U.S. commercial launch of AGAMREE® (vamorolone) oral suspension 40 mg/mL for the treatment of Duchenne Muscular Dystrophy ("DMD") in patients aged two years and older. Following the U.S. Food and Drug Administration ("FDA") approval on October 26, 2023, AGAMREE is now available by prescription and dispensed throughout the United States through a specialty pharmacy network. "Today, we proudly announced the U.S. commercial availability of AGAMREE, an innovative alternative steroid treatment for Duchenne Muscular Dystrophy. This significant milestone offers hope for improved quality of life for individuals living with this devastating rare disease, as current steroid treatment options often involve a significant side effect burden," stated Richard J. Daly, CEO of Catalyst. "With the potential to extend ambulation and mobility for patients, AGAMREE marks an important therapeutic advancement with the prospect of reshaping the treatment paradigm for this life-threatening condition. We are firmly positioned to leverage our well-established commercial capabilities for a successful U.S. launch and remain resolute in our mission to help ensure that all patients have access to this novel therapy. Our Catalyst Pathways, a personalized program, is readily available to assist Duchenne Muscular Dystrophy patients and their families with the one‐on‐one education and financial support they need, thereby enhancing the access and affordability of AGAMREE for every patient. We eagerly look forward to collaborating with healthcare providers to facilitate patient access, reinforcing our unwavering dedication to serving our patient communities." Catalyst Pathways® Patient Assistance Program for AGAMREE® is a comprehensive patient support program that includes a dedicated, personalized support team that assists families throughout the AGAMREE treatment journey for eligible patients. For more information, caregivers and healthcare professionals can call 1-833-422-8259 or visit the Catalyst Pathways® website at . Duchenne Muscular Dystrophy, DMD, the most common form of muscular dystrophy, is a rare and life-threatening neuromuscular disorder characterized by progressive muscle dysfunction, ultimately leading to loss of ambulation, respiratory failure, and fatality. Current standard treatment for DMD involves corticosteroids, which often come with significant side effects. It is estimated that between 11,000 and 13,000 patients in the U.S. are affected by DMD, with approximately 70% of patients currently receiving a corticosteroid treatment. Steroids are expected to remain the backbone of therapy for DMD patients and dosed concomitantly with other therapies. The FDA's approval of AGAMREE® was based on the data from the pivotal Phase 2b VISION-DMD study as supplemented with safety information collected from three open-label studies, including extension studies. In these trials, AGAMREE was administered at doses ranging from 2 to 6 mg/kg/day, extending for up to 48 months. Compared with current standard-of-care corticosteroids, this novel corticosteroid treatment exhibited comparable efficacy, with data suggesting a reduction in adverse events, notably related to bone health, growth trajectory, and improved behavior. About AGAMREE® (vamorolone) AGAMREE's unique mode of action is based on differential effects on glucocorticoid and mineralocorticoid receptors and modifying further downstream activity. As such, it is considered a novel corticosteroid with dissociative properties in maintaining efficacy that we hope has the potential to demonstrate comparable efficacy to steroids, with the potential for a better-tolerated side effect profile. This mechanism of action may allow AGAMREE to emerge as an effective alternative to the current standard of care corticosteroids in children, adolescents, and adult patients with DMD. In the pivotal VISION-DMD study, AGAMREE met the primary endpoint Time to Stand (TTSTAND) velocity versus placebo (p=0.002) at 24 weeks of treatment and showed a good safety and tolerability profile. The most commonly reported adverse events versus placebo from the VISION-DMD study were cushingoid features, psychiatric disorders, vomiting, weight increases, and vitamin D deficiency. Adverse events were generally of mild to moderate severity. AGAMREE was granted U.S. FDA approval on October 26, 2023, and has been granted Orphan Drug Exclusivity (ODE) for DMD and New Chemical Entity Exclusivity (NCE) in the U.S., conferring seven years and 5 years of exclusivity, respectively, from the date of approval. AGAMREE also has granted pending patents that could provide protection until 2040. In Europe, it has received Promising Innovative Medicine (PIM) status from the UK MHRA for DMD.

– Topline data from ongoing Phase 1/2 trials of INZ-701 in adults with ABCC6 Deficiency and ENPP1 Deficiency expected in early April – – Phase 1 trial of INZ-701 in end-stage kidney disease (ESKD) patients receiving hemodialysis (SEAPORT-1) now underway (NCT06283589), with topline data expected in Q4 2024 – – Launched global patient registry (PROPEL) in partnership with GACI Global to advance understanding of ENPP1 Deficiency and infantile-onset ABCC6 Deficiency (NCT06302439) – – Cash, cash equivalents, and short-term investments as of December 31, 2023 expected to fund operations into the fourth quarter of 2025 – BOSTON, March 12, 2024 (GLOBE NEWSWIRE) -- Inozyme Pharma, Inc. (Nasdaq: INZY) (“the Company” or “Inozyme”), a clinical-stage rare disease biopharmaceutical company developing novel therapeutics for the treatment of pathologic mineralization and intimal proliferation, today reported financial results for the full year ended December 31, 2023, and provided recent business highlights. “We believe we are well-positioned to continue to advance INZ-701 through several anticipated value-creating milestones in the year ahead,” said Douglas A. Treco, Ph.D., CEO of Inozyme Pharma. “Of note, we are on track to report topline data from our ongoing Phase 1/2 trials in adult patients with ABCC6 Deficiency and ENPP1 Deficiency in early April. Data from these trials along with learnings from our recently launched global patient registry in partnership with GACI Global have the potential to play a meaningful role in bringing INZ-701 closer to patients facing these challenging diseases.” Dr. Treco added, “Beyond our two lead indications, today we are pleased to announce the initiation of our Phase 1 SEAPORT-1 trial in patients with end-stage kidney disease (ESKD) receiving hemodialysis, of which calciphylaxis is a severe complication. Calciphylaxis represents a devastating condition characterized by pathologic mineralization and intimal proliferation. Clinical data to date have demonstrated that INZ-701 was generally safe and well tolerated and meaningfully increased PPi levels in adults with ENPP1 and ABCC6 Deficiencies, conditions that share similar pathology to calciphylaxis, supporting the idea that INZ-701 could ultimately serve as a therapeutic option for this underserved population.” Recent Updates and Anticipated Milestones Phase 1/2 Clinical Trials of INZ-701 in Adults with ABCC6 Deficiency (pseudoxanthoma elasticum or PXE) and ENPP1 Deficiency. The Company expects to report topline data from its ongoing Phase 1/2 trial of INZ-701 in adults with ABCC6 Deficiency and topline data from the first three cohorts of its ongoing Phase 1/2 trial in adults with ENPP1 Deficiency in early April. Global ENPP1 Deficiency and Infantile-Onset ABCC6 Deficiency Patient Registry (PROPEL NCT06302439). The Company announced the launch of a global patient registry in partnership with GACI Global, a patient advocacy group that connects families affected by generalized arterial calcification of infancy (GACI) or autosomal recessive hypophosphatemic rickets type 2 (ARHR2). The patient registry is designed to better characterize the natural history, disease course, long-term outcomes, and true disease burden in patients with ENPP1 Deficiency and infantile-onset ABCC6 Deficiency (GACI Type 2). The registry will assess three distinct cohorts: Patients of all ages with ENPP1 Deficiency with evidence of biallelic ENPP1 variantsPatients with evidence of monoallelic ENPP1 variants and disease-related symptomsPatients under 18 years of age with infantile-onset ABCC6 Deficiency with monoallelic or biallelic ABCC6 variantsTo date, the Company has identified over 1,000 patients globally with confirmed or suspected ENPP1 Deficiency and collected data on a number of symptomatic ENPP1 Deficiency patients with monoallelic ENPP1 mutations. “At GACI Global, we are dedicated to furthering the understanding of these devastating diseases in order to advance the development of potential treatments,” said Christine O’Brien, co-president of GACI Global. “Our partnership with Inozyme has played an important role in that mission while ensuring the GACI community has a voice.” Phase 1 SEAPORT-1 Trial of INZ-701 in Patients with ESKD Receiving Hemodialysis Now Underway (NCT06283589). The Company today announced the initiation of its Phase 1 SEAPORT-1 trial of INZ-701 in patients with ESKD receiving hemodialysis, of which calciphylaxis is a severe complication. The trial is designed to assess safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of INZ-701 in up to 10 patients with ESKD receiving hemodialysis. Patients will receive 1.8 mg/kg of INZ-701 once weekly, coinciding with their hemodialysis treatment, for a total of 30 days. The study’s primary endpoint will assess safety and change from baseline plasma PPi concentration, with secondary endpoints including PK and PD parameters. Topline data from the study are expected in the fourth quarter of 2024.Inozyme previously presented data at the American Society of Nephrology (ASN) Kidney Week 2023 in October 2023 and at the European Calcified Tissue Society Congress (ECTS) in May 2022, which showed the following: Patients with ESKD had significantly lower PPi levels compared to healthy subjectsPatients with patients with calciphylaxis had significantly lower PPi levels when compared with ESKD patients without calciphylaxisLow PPi levels were associated with morbidity and predicted 6-month mortality among ESKD patients with calciphylaxisLow PPi levels are correlated with higher numbers of skin lesions in calciphylaxis “ESKD patients suffering from calciphylaxis face a poor quality of life and, unfortunately, a particularly dismal prognosis,” said Sagar Nigwekar, M.D., MMSc, Co-Director, Kidney Research Center, Massachusetts General Hospital. “I am hopeful that INZ-701 could serve as a much-needed treatment for this underserved patient population. I look forward to the data from this study, as well as more advanced clinical trials of INZ-701 in calciphylaxis.” Anticipated Milestones ENPP1 Deficiency Topline data from first three cohorts of ongoing Phase 1/2 trial in adults through 48 weeks – Early April 2024Initiation of the ENERGY-2 pivotal trial in infants, Ex-U.S. – 2H 2024Interim data from the ENERGY-1 Phase 1b trial in infants – 2H 2024Topline data from the ENERGY-3 pivotal trial in pediatric patients – Mid-2025 ABCC6 Deficiency Topline data from ongoing Phase 1/2 trial in adults through 48 weeks – Early April 2024Initiation of Phase 3 clinical trial, subject to regulatory review and sufficient funding – Q1 2025 Calciphylaxis Interim data from SEAPORT-1 Phase 1 trial in patients with ESKD receiving hemodialysis – Q4 2024 Financial Results for the Year Ended December 31, 2023 Cash Position and Financial Guidance – Cash, cash equivalents, and short-term investments were $188.6 million as of December 31, 2023. Based on its current plans, the Company anticipates its cash, cash equivalents, and short-term investments as of December 31, 2023, will enable the Company to fund cash flow requirements into the fourth quarter of 2025. Research and Development (R&D) Expenses – R&D expenses were $54.8 million for the year ended December 31, 2023, compared to $47.8 million for the year ended December 31, 2022. This increase was primarily due to an increase in chemistry, manufacturing, and controls expense to support our ongoing clinical trials and prepare for potential commercialization and personnel-related costs. General and Administrative (G&A) Expenses – G&A expenses were $20.8 million for the year ended December 31, 2023, compared to $20.8 million for the year ended December 31, 2022. The expenses were flat year over year. Net Loss – Net loss was $71.2 million, or $1.37 loss per share, for the year ended December 31, 2023, compared to $67.1 million, or $1.78 loss per share, for the year ended December 31, 2022. About ENPP1 Deficiency ENPP1 Deficiency is a progressively debilitating condition of the vasculature, soft tissue, and skeleton with a prevalence of approximately 1 in 64,000 pregnancies worldwide. Although ENPP1 Deficiency was initially described in patients with biallelic ENPP1 Deficiency (homozygous or compound heterozygous mutations), many patients with monoallelic ENPP1 Deficiency (heterozygous mutations) have clinical symptoms, potentially increasing the worldwide prevalence. Individuals who present in utero or in infancy are typically diagnosed with generalized arterial calcification of infancy (GACI Type 1) and approximately 50% of infants die within six months of birth. Children with ENPP1 Deficiency typically develop rickets, a condition diagnosed as autosomal-recessive hypophosphatemic rickets type 2 (ARHR2), while adolescents and adults can develop osteomalacia (softened bones). ARHR2 and osteomalacia lead to pain and mobility issues. Patients can also exhibit signs and symptoms of hearing loss, arterial and joint calcification, and cardiovascular complications. There are no approved therapies for ENPP1 Deficiency. About ABCC6 Deficiency ABCC6 Deficiency is a progressively debilitating condition of the vasculature and soft tissue that is estimated to affect approximately 1 in 25,000 to 1 in 50,000 individuals worldwide. Infants with ABCC6 Deficiency are diagnosed with generalized arterial calcification of infancy (GACI Type 2), a condition that resembles GACI Type 1, the infant form of ENPP1 Deficiency. Pediatric patients who survive the first year of life may develop neurological disease, including stroke, and cardiovascular disease secondary to ongoing vascular calcification and stenosis. In older individuals, ABCC6 Deficiency presents as pseudoxanthoma elasticum (PXE), which is characterized by pathologic mineralization in blood vessels and soft tissues clinically affecting the skin, eyes, and vascular system. There are no approved therapies for ABCC6 Deficiency. About Calciphylaxis Calciphylaxis is a rare disorder with a high mortality rate that mostly affects patients with end-stage kidney disease (ESKD). The disease is associated with low levels of pyrophosphate (PPi) and is characterized by pathologic mineralization (i.e. calcification) and intimal proliferation (the overgrowth of smooth muscle cells inside blood vessels) of the vasculature in the skin and fatty tissue leading to poor blood flow, blood clots, painful skin ulcers, serious infections, and death. Patients with calciphylaxis have a reported one-year survival rate of approximately 50%. The estimated incidence of calciphylaxis is approximately 3.5 per 1,000 patients with ESKD with approximately 5,000 new patients presenting annually across major geographies. There are no approved therapies for calciphylaxis. About INZ-701 INZ-701, a recombinant Fc fusion protein, is an ENPP1 enzyme replacement therapy (ERT) in development for the treatment of rare disorders of the vasculature, soft tissue, and skeleton. INZ-701 metabolizes ATP to generate PPi, a natural inhibitor of mineralization, and AMP, which can be processed to phosphate and adenosine, the latter being a natural inhibitor of intimal proliferation. In preclinical studies, the experimental therapy has shown potential to prevent pathologic mineralization and intimal proliferation, which can drive morbidity and mortality in devastating disorders such as ENPP1 Deficiency, ABCC6 Deficiency and calciphylaxis. Clinical data to date have demonstrated that INZ-701 was generally safe and well tolerated and meaningfully increased PPi levels in multiple clinical trials. About GACI Global GACI Global is a nonprofit organization whose mission is to connect families affected by generalized arterial calcification of infancy or hypophosphatemic rickets to each other and to the medical community. The organization strives to provide current educational resources and supports ongoing research. For more information, please visit https://gaciglobal.org.
