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.

Retrospective analysis suggests Acthar Gel treatment was associated with similar improvement in health status and overall symptom reduction in African Americans and non-African Americans with symptomatic sarcoidosis1 Findings on treatment response and physician-reported outcomes indicate that Acthar Gel may be a viable treatment option for both African American and non-African American sarcoidosis patients1 DUBLIN, March 11, 2024 /PRNewswire/ -- Mallinckrodt plc, a global specialty pharmaceutical company, today announced the publication of findings from a retrospective chart review of Acthar® Gel (repository corticotropin injection) treatment outcomes for African American and non-African American patients with symptomatic sarcoidosis – including treatment patterns, co-medication use, and overall health outcomes.1 This analysis suggested that Acthar Gel treatment was associated with similar improvements in health outcomes, a reduction in symptoms, and reduced co-medication use in both African Americans and non-African Americans with symptomatic sarcoidosis.1 The manuscript was recently published online in Therapeutics & Clinical Risk Management. This research builds upon findings from a study investigating the clinical and real-world outcomes of Acthar Gel treatment in a subgroup of African Americans with symptomatic sarcoidosis, previously presented at the 2022 American Thoracic Society Annual International Conference in San Francisco, CA, and published in Therapeutic Advances in Respiratory Disease in 2019.2 Acthar is a naturally sourced complex mixture of adrenocorticotropic hormone analogs and other pituitary peptides.3 Acthar Gel is approved by the U.S. Food and Drug Administration (FDA) for the treatment of several autoimmune disorders and medical conditions known to cause inflammation, including symptomatic sarcoidosis.3 Please see additional indications and Important Safety Information below. "The results of this retrospective medical chart review highlight unmet needs that exist for African American patients with symptomatic sarcoidosis, who are disproportionately affected by the disease, and reinforce Acthar Gel's potential to help improve health outcomes for appropriate patients,"1,4,5 said George Wan, Ph.D., M.P.H., Vice President, Evidence Generation and Data Sciences, Mallinckrodt. "This research reflects Mallinckrodt's commitment to collecting real-world data on the relationship between patient characteristics, treatment patterns, and outcomes to support clinicians' treatment decisions and address disparities in symptomatic sarcoidosis care."1 About the Study:1 In this retrospective analysis, a national database of Acthar Gel prescribers and the American Medical Association Physician Master were merged to obtain a sample of 98 physicians to provide data on the last 6 consecutive patients seen who met the study's eligibility criteria. The medical records were extracted for adult patients (≥18 years) with a diagnosis of advanced symptomatic sarcoidosis, who had ≥1 symptom, and who had either completed at least one course of Acthar Gel or had received Acthar Gel for at least 6 months during data collection. A total of 272 patients with symptomatic sarcoidosis were included in this analysis (African American (AA): n=168; non-African American (non-AA): n=104). Most patients in both race groups were diagnosed with stage 3 or 4 sarcoidosis based on chest imaging and biopsy (AA: 61.3%, n=103 vs. non-AA: 68.3%, n=71; p=0.2453). Per an assessment of patient characteristics and Acthar Gel treatment patterns, this analysis suggests that the average time since the first diagnosis of sarcoidosis was slightly longer among AA than non-AA (mean ± SD: 5.2 ± 7.6 years vs. 4.3 ± 5.1 years; p>0.05).1 Further, a lower proportion of AA vs. non-AA had completed a course of Acthar Gel therapy (44%, n=74 vs. 55.8%, n=58; p=0.0602) during the data collection period,1 and the duration of Acthar Gel treatment was slightly longer among AA vs. non-AA (mean ± SD: 31.7 ± 32 vs. 29 ± 27.4 weeks; p>0.05).1 "This research underscores the importance of conducting real-world studies to provide data that helps to recognize the disparities in symptomatic sarcoidosis care and address unmet needs to better support health outcomes for all appropriate patients," said Mary McGowan, Chief Executive Officer, Foundation for Sarcoidosis Research (FSR). FSR is the leading international organization dedicated to finding a cure for sarcoidosis and improving care for sarcoidosis patients through research, education, and support. Key Findings: Co-Medication Utilization Patterns1 Significantly fewer patients among both race groups were on any co-medication after Acthar Gel initiation (p<0.0001): AA before: 88.1%, n=148 vs. after: 20.2%, n=34 Non-AA before: 83.7%, n=87 vs. after: 24%, n=25 More AA had a reduction in any co-medication use after Acthar Gel initiation (AA: -77% vs. non-AA: -71%; p<0.0001). After Acthar Gel initiation, fewer AA (before: 59.5%, n=100 vs. after: 11.9%, n=20; p<0.0001) and non-AA (before: 65.4%, n=68 vs. after: 14.4%, n=15; p<0.0001) were on glucocorticoids. Overall, the mean prednisone dose reduced after Acthar Gel initiation among AA (before: 18.5 mg/day vs. after: 10.1 mg/day) and non-AA (before: 17.6 mg/day vs. after: 10 mg/day). The proportion of patients on prednisone daily dose of <10 mg increased after Acthar Gel initiation among both race groups (AA before: 27.8%, n=27/97 vs. after: 31.6%, n=6/19; non-AA before: 13.6%, n=9/66 vs. after: 60%, n=9/15). Physicians' Assessment of Improvement1 The health status of 95.2% (n=160) of AA and 97.1% (n=101) of non-AA improved following treatment with Acthar Gel, based on physician-provided assessments of patient outcomes. Treatment response to overall symptoms was not statistically significantly different between both race groups (AA: 72.6%, n=122 vs. non-AA: 70.2%, n=73) The most frequently reported changes in symptoms following Acthar Gel treatment in both race groups were: Reduction in inflammation (AA: 33.9%, n=57 vs. non-AA: 32.7%, n=34) Improvement in quality of life (AA: 31.5%, n=53 vs. non-AA: 34.6%, n=36) Improvement in lung function (AA: 30.4%, n=51 vs. non-AA: 53.8%, n=56; p<0.05) Reduction in fatigue (AA: 27.4%, n=46 vs. non-AA: 35.6%, n=37) Limitations:1 Data retrospectively collected from medical charts of patients may have omissions and errors. Completeness of information was assessed to the extent possible to minimize bias resulting from any missing data. In addition, only data available in medical charts or known to be complete to the respondents were extracted. Additional limitations of this study include: Physicians' standards for the interpretation of change in each patient's health status vary which may result in bias due to over- or under-estimation of the effectiveness of Acthar Gel. This study was unable to quantify clinical data such as diagnostic and safety measures, clinical and sustained response after treatment, and reasons for discontinuation or dose adjustments related to Acthar Gel. Due to the exploratory nature of this analysis, data were not collected for other medications besides Acthar Gel. Data on adverse reactions in this population, drivers of the decision to use Acthar Gel, and detailed information on prior therapies were not captured. This study was sponsored by Mallinckrodt Pharmaceuticals. INDICATIONS Acthar Gel is indicated for: Inducing a diuresis or a remission of proteinuria in nephrotic syndrome without uremia of the idiopathic type or that due to lupus erythematosus Monotherapy for the treatment of infantile spasms in infants and children under 2 years of age Treatment of acute exacerbations of multiple sclerosis in adults. Controlled clinical trials have shown Acthar to be effective in speeding the resolution of acute exacerbations of multiple sclerosis. However, there is no evidence that it affects the ultimate outcome or natural history of the disease Severe acute and chronic allergic and inflammatory processes involving the eye and its adnexa such as: keratitis, iritis, iridocyclitis, diffuse posterior uveitis and choroiditis, optic neuritis, chorioretinitis, anterior segment inflammation Symptomatic sarcoidosis Treatment during an exacerbation or as maintenance therapy in selected cases of systemic lupus erythematosus Treatment during an exacerbation or as maintenance therapy in selected cases of dermatomyositis (polymyositis) Adjunctive therapy for short-term administration (to tide the patient over an acute episode or exacerbation) in: psoriatic arthritis; rheumatoid arthritis, including juvenile rheumatoid arthritis (selected cases may require low-dose maintenance therapy); ankylosing spondylitis IMPORTANT SAFETY INFORMATION Contraindications Acthar is contraindicated: For intravenous administration In infants under 2 years of age who have suspected congenital infections With concomitant administration of live or live attenuated vaccines in patients receiving immunosuppressive doses of Acthar In patients with scleroderma, osteoporosis, systemic fungal infections, ocular herpes simplex, recent surgery, history of the presence of a peptic ulcer, congestive heart failure, uncontrolled hypertension, primary adrenocortical insufficiency, adrenocortical hyperfunction, or sensitivity to proteins of porcine origin Warnings and Precautions The adverse effects of Acthar are related primarily to its steroidogenic effects Acthar may increase susceptibility to new infection or reactivation of latent infections Suppression of the hypothalamic-pituitary-adrenal (HPA) axis may occur following prolonged therapy with the potential for adrenal insufficiency after withdrawal of the medication. Adrenal insufficiency may be minimized by tapering of the dose when discontinuing treatment. During recovery of the adrenal gland patients should be protected from the stress (e.g., trauma or surgery) by the use of corticosteroids. Monitor patients for effects of HPA axis suppression after stopping treatment Cushing's syndrome may occur during therapy but generally resolves after therapy is stopped. Monitor patients for signs and symptoms Acthar can cause elevation of blood pressure, salt and water retention, and hypokalemia. Monitor blood pressure and sodium and potassium levels Acthar often acts by masking symptoms of other diseases/disorders. Monitor patients carefully during and for a period following discontinuation of therapy Acthar can cause gastrointestinal (GI) bleeding and gastric ulcer. There is also an increased risk for perforation in patients with certain GI disorders. Monitor for signs of perforation and bleeding Acthar may be associated with central nervous system effects ranging from euphoria, insomnia, irritability, mood swings, personality changes, and severe depression to psychosis. Existing conditions may be aggravated Patients with comorbid disease may have that disease worsened. Caution should be used when prescribing Acthar in patients with diabetes and myasthenia gravis Prolonged use of Acthar may produce cataracts, glaucoma, and secondary ocular infections. Monitor for signs and symptoms Acthar is immunogenic and prolonged administration of Acthar may increase the risk of hypersensitivity reactions. Cases of anaphylaxis have been reported in the postmarketing setting. Neutralizing antibodies with chronic administration may lead to loss of endogenous ACTH and Acthar activity There may be an enhanced effect in patients with hypothyroidism and in those with cirrhosis of the liver Long-term use may have negative effects on growth and physical development in children. Monitor pediatric patients Decrease in bone density may occur. Bone density should be monitored in patients on long-term therapy Adverse Reactions Commonly reported postmarketing adverse reactions for Acthar include injection site reaction, asthenic conditions (including fatigue, malaise, asthenia, and lethargy), fluid retention (including peripheral swelling), insomnia, headache, and blood glucose increased The most common adverse reactions for the treatment of infantile spasms (IS) are increased risk of infections, convulsions, hypertension, irritability, and pyrexia. Some patients with IS progress to other forms of seizures; IS sometimes masks these seizures, which may become visible once the clinical spasms from IS resolve Pregnancy Acthar may cause fetal harm when administered to a pregnant woman Please see full Prescribing Information for additional Important Safety Information. ABOUT SYMPTOMATIC SARCOIDOSIS Sarcoidosis is a challenging and rare multisystem disease.6 In some cases, the symptoms may come and go throughout a lifetime.6 This is referred to as symptomatic sarcoidosis.6 In people with sarcoidosis, the immune system overreacts, forming clumps of cells called granulomas that result in inflammation to the body's tissues.7 The disease can impact any organ, but it most often impacts the lungs, lymph nodes, eyes, liver, and skin.8 Nearly 90 percent of people with sarcoidosis will suffer lung problems.8 Concomitant involvement of organs outside of the lungs is common, occurring in more than half of all sarcoidosis cases, according to one study.2 ABOUT MALLINCKRODT Mallinckrodt is a global business consisting of multiple wholly owned subsidiaries that develop, manufacture, market and distribute specialty pharmaceutical products and therapies.
