About OMS906 OMS906 is an investigational humanized monoclonal antibody targeting mannan-binding lectin-associated serine protease-3 (MASP-3), the key activator of the complement system’s alternative pathway. The complement system plays a central role in inflammation and becomes activated as a result of tissue damage or microbial infection. Responsible for the conversion of pro-complement factor D to complement factor D, MASP-3 is believed to be the premier target in the alternative pathway – it has the lowest native circulating level and low relative clearance compared to the other alternative pathway proteins and, unlike C5 and C3 blockers, MASP-3 inhibition leaves intact the lytic arm of the classical pathway, important for fighting infection. Also, unlike other components of the alternative pathway, MASP-3 is believed not to be an acute phase reactant, which could provide a significant advantage to MASP-3 inhibitors, like OMS906, over other alternative pathway inhibitors. MASP-3 inhibitors are thought to have preventive and/or therapeutic effects across a broad range of diseases including paroxysmal nocturnal hemoglobinuria (PNH), hemolytic uremic syndrome (HUS), atypical HUS, traumatic brain injury, arthritis, wet age-related macular degeneration, ischemia-reperfusion injury, transplant-related complications and other immune-related disorders. About Omeros Corporation Omeros is an innovative biopharmaceutical company committed to discovering, developing and commercializing small-molecule and protein therapeutics for large-market and orphan indications targeting immunologic disorders including complement-mediated diseases, cancers, and addictive and compulsive disorders. Omeros’ lead MASP-2 inhibitor narsoplimab targets the lectin pathway of complement and is the subject of a biologics license application pending before FDA for the treatment of hematopoietic stem cell transplant-associated thrombotic microangiopathy. Omeros’ long-acting MASP-2 inhibitor OMS1029 is currently in a Phase 1 multi-ascending-dose clinical trial. OMS906, Omeros’ inhibitor of MASP-3, the key activator of the alternative pathway of complement, is advancing toward Phase 3 clinical trials for paroxysmal nocturnal hemoglobinuria and complement 3 glomerulopathy. Funded by the National Institute on Drug Abuse, Omeros’ lead phosphodiesterase 7 inhibitor OMS527 is in clinical development for the treatment of cocaine use disorder and, in addition, is being developed as a therapeutic for other addictions as well as for a major complication of treatment for movement disorders.

Data demonstrated effective control of intravascular and extravascular hemolysis through 48 weeks Results showed increase in mean hemoglobin levels were maintained through 48 weeks WILMINGTON, Del.--(BUSINESS WIRE)-- Positive results from the 24-week and long-term extension (LTE) period of the pivotal ALPHA Phase III trial showed danicopan as add-on to standard of care C5 inhibitor therapy ULTOMIRIS® (ravulizumab-cwvz) or SOLIRIS® (eculizumab) continued to demonstrate clinical benefit for patients with paroxysmal nocturnal hemoglobinuria (PNH) who experience clinically significant extravascular hemolysis (EVH).1 This press release features multimedia. View the full release here: Hemoglobin levels improved with danicopan at 12 weeks and were maintained through 48 weeks. (Photo: Business Wire) Results from the trial were presented today at the 65th American Society of Hematology (ASH) Annual Meeting and Exposition in San Diego, California. Danicopan is an investigational, first-in-class, oral, Factor D inhibitor. Data showed that improvements in mean hemoglobin levels and absolute reticulocyte count (ARC) levels, which were demonstrated at 12 weeks, were maintained through 48 weeks.1 PNH is a rare and severe blood disorder characterized by the destruction of red blood cells within blood vessels, known as intravascular hemolysis (IVH), and white blood cell and platelet activation that can cause thrombosis (blood clots) and result in organ damage and potentially premature death.2-4 Immediate, complete and sustained terminal complement inhibition by blocking the C5 protein with ULTOMIRIS or SOLIRIS helps reduce symptoms and complications, resulting in improved survival for patients with PNH.4-7 Approximately 10-20% of people living with PNH who are treated with a C5 inhibitor experience clinically significant EVH, which can result in continued symptoms of anemia and require blood transfusions.2,8-12 Austin Kulasekararaj, MD, Consultant Hematologist at King's College Hospital, London and investigator in the ALPHA trial, said: “These new data further demonstrate the potential of danicopan as add-on to ULTOMIRIS or SOLIRIS to address the needs of the small subset of patients with PNH who experience clinically significant EVH. Expanding on positive 12-week results, the findings demonstrate sustained improvements in hemoglobin levels for up to 48 weeks, while also maintaining disease control, as measured by lactate dehydrogenase levels.” Gianluca Pirozzi, Senior Vice President, Head of Development, Regulatory and Safety, Alexion, said: “Unlike IVH, EVH is not life-threatening, but its manifestations can be burdensome for people living with this condition, which is why we continue to explore the potential of the complement system to advance patient care. The pivotal ALPHA results suggest that dual complement pathway inhibition at Factor D and C5 may be an optimal treatment approach for the 10-20% of patients with PNH who experience clinically significant EVH. Importantly, C5 inhibition maintains effective IVH control, which is critical for patients, and the addition of Factor D inhibition addresses signs and symptoms of EVH.” The pivotal ALPHA Phase III trial is designed as a superiority study to evaluate the efficacy and safety of danicopan as an add-on to C5 inhibitor therapy ULTOMIRIS or SOLIRIS in patients with PNH who experience clinically significant EVH. A total of 86 patients were randomized. The prespecified interim analysis (primary analysis) occurred after 63 participants either completed or discontinued from the primary treatment period of 12 weeks. Following the 12-week randomized control period, patients were eligible to enroll in an open-label treatment period for an additional 12 weeks. During the open-label period, participants receiving placebo plus ULTOMIRIS or SOLIRIS switched to danicopan plus ULTOMIRIS or SOLIRIS (placebo-danicopan), and participants receiving add-on therapy with danicopan continued treatment with danicopan add-on therapy (danicopan-danicopan). The open-label treatment period was followed by the option to join a two-year LTE period during which all participants received danicopan add-on therapy. At the time of data cut-off on September 20, 2022, 60 of the 63 patients who were included in the primary analysis had reached 24 weeks and entered the LTE.1 Data showed that the significant improvements in hemoglobin levels observed at 12 weeks [LSM (SEM) change 2.94 (0.21) g/dL] continued at 24 weeks [LSM (SEM) change 3.17 (0.30) g/dL] among patients treated with danicopan plus ULTOMIRIS or SOLIRIS and were sustained through 48 weeks.1 Secondary endpoints measured at 24 weeks include change from baseline in hemoglobin, ARC, and lactate dehydrogenase (LDH) levels; the percentage of patients with hemoglobin increase of ≥2 g/dL in the absence of transfusion; and the percentage of patients with transfusion avoidance.1 All key secondary endpoints met superiority in favor of danicopan plus ULTOMIRIS or SOLIRIS compared to placebo plus ULTOMIRIS or SOLIRIS at 12 weeks, and data showed benefits were maintained at 24 weeks in the danicopan-danicopan arm.1 Further, all key secondary endpoints showed meaningful improvement at 24 weeks in patients who switched from placebo to add-on treatment with danicopan at 12 weeks, including ARC levels and percentage of patients with transfusion avoidance, two indicators of potential EVH.1 Additionally, mean (SD) LDH levels were maintained from baseline through 48 weeks in both treatment arms, demonstrating effective control of terminal complement activity and IVH with ULTOMIRIS or SOLIRIS.1 Summary of efficacy resultsi Hemoglobin and ARC levels improved with danicopan at 12 weeks and were maintained through 48 weeks (please see hemoglobin and ARC level graphs included in the image carousel).

LDH, lactate dehydrogenase; ARC, absolute reticulocyte count; LSM, least squares mean; SEM, standard error of the mean; ULN, upper limit of normal. Results from the ALPHA Phase III trial and LTE showed danicopan is generally well tolerated, and no new safety concerns were identified. The safety analysis was performed using data from all participants who took at least one dose of danicopan (n=80). The most common treatment-emergent adverse events (TEAEs) (≥10%) were COVID-19 (21.3%), diarrhea (15%), headache (15%), pyrexia (13.8%), nausea (12.5%) and fatigue (10%).1 Additionally, an analysis of patient-reported outcomes from the ALPHA Phase III trial at 24 weeks was also presented at ASH, suggesting danicopan plus ULTOMIRIS or SOLIRIS has the potential to improve quality of life compared to C5 inhibitor therapy alone for the 10-20% of patients with PNH who experience clinically significant EVH.13 Findings showed clinically relevant patient-reported outcomes were observed in patients treated with danicopan as add-on to ULTOMIRIS or SOLIRIS during the first 12 weeks of treatment, compared to placebo plus C5 inhibition. Additionally, data showed improvements in Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 Scale (EORTC-QLQ-C30) scores were maintained during the open-label period to 24 weeks in the danicopan-danicopan arm and improved at 24 weeks in the placebo-danicopan arm.13 ALPHA Phase III trial results from the primary prespecified interim analysis at 12 weeks were presented at the European Hematology Association (EHA) 2023 Hybrid Congress and published in The Lancet Haematology. Regulatory submissions for danicopan are currently under review with multiple global health authorities. INDICATION(S) & IMPORTANT SAFETY INFORMATION for ULTOMIRIS® (ravulizumab-cwvz) What is ULTOMIRIS? ULTOMIRIS is a prescription medicine used to treat: adults and children 1 month of age and older with a disease called Paroxysmal Nocturnal Hemoglobinuria (PNH). adults and children 1 month of age and older with a disease called atypical Hemolytic Uremic Syndrome (aHUS). ULTOMIRIS is not used in treating people with Shiga toxin E. coli related hemolytic uremic syndrome (STEC-HUS). adults with a disease called generalized Myasthenia Gravis (gMG) who are anti-acetylcholine receptor (AChR) antibody positive. adults with PNH or aHUS when administered subcutaneously (under your skin). It is not known if ULTOMIRIS is safe and effective in children younger than 1 month of age. It is not known if ULTOMIRIS is safe and effective for the treatment of gMG in children. Subcutaneous administration of ULTOMIRIS has not been evaluated and is not approved for use in children. IMPORTANT SAFETY INFORMATION What is the most important information I should know about ULTOMIRIS? ULTOMIRIS is a medicine that affects your immune system and can lower the ability of your immune system to fight infections. ULTOMIRIS increases your chance of getting serious and life-threatening meningococcal infections that may quickly become life-threatening and cause death if not recognized and treated early. You must receive meningococcal vaccines at least 2 weeks before your first dose of ULTOMIRIS if you are not vaccinated. If your healthcare provider decided that urgent treatment with ULTOMIRIS is needed, you should receive meningococcal vaccination as soon as possible. If you have not been vaccinated and ULTOMIRIS therapy must be initiated immediately, you should also receive 2 weeks of antibiotics with your vaccinations. If you had a meningococcal vaccine in the past, you might need additional vaccination. Your healthcare provider will decide if you need additional vaccination. Meningococcal vaccines reduce but do not prevent all meningococcal infections. Call your healthcare provider or get emergency medical care right away if you get any of these signs and symptoms of a meningococcal infection: headache with nausea or vomiting, headache and fever, headache with a stiff neck or stiff back, fever, fever and a rash, confusion, muscle aches with flu-like symptoms and eyes sensitive to light. Your healthcare provider will give you a Patient Safety Card about the risk of meningococcal infection. Carry it with you at all times during treatment and for 8 months after your last ULTOMIRIS dose. It is important to show this card to any healthcare provider or nurse to help them diagnose and treat you quickly. ULTOMIRIS is only available through a program called the ULTOMIRIS REMS. Before you can receive ULTOMIRIS, your healthcare provider must: enroll in the ULTOMIRIS REMS program; counsel you about the risk of meningococcal infection; give you information and a Patient Safety Card about the symptoms and your risk of meningococcal infection (as discussed above); and make sure that you are vaccinated with a meningococcal vaccine, and if needed, get revaccinated with the meningococcal vaccine. Ask your healthcare provider if you are not sure if you need to be revaccinated. ULTOMIRIS may also increase the risk of other types of serious infections. Make sure your child receives vaccinations against Streptococcus pneumoniae and Haemophilus influenzae type b (Hib) if treated with ULTOMIRIS. Call your healthcare provider right away if you have any new signs or symptoms of infection. Who should not receive ULTOMIRIS? Do not receive ULTOMIRIS if you have a meningococcal infection or have not been vaccinated against meningococcal infection unless your healthcare provider decides that urgent treatment with ULTOMIRIS is needed. Before you receive ULTOMIRIS, tell your healthcare provider about all of your medical conditions, including if you: have an infection or fever, are pregnant or plan to become pregnant, and are breastfeeding or plan to breastfeed. It is not known if ULTOMIRIS will harm your unborn baby or if it passes into your breast milk. You should not breastfeed during treatment and for 8 months after your final dose of ULTOMIRIS. Tell your healthcare provider about all the vaccines you receive and medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements which could affect your treatment. If you have PNH and you stop receiving ULTOMIRIS, your healthcare provider will need to monitor you closely for at least 16 weeks after you stop ULTOMIRIS. Stopping ULTOMIRIS may cause breakdown of your red blood cells due to PNH. Symptoms or problems that can happen due to red blood cell breakdown include: drop in your red blood cell count, tiredness, blood in your urine, stomach-area (abdomen) pain, shortness of breath, blood clots, trouble swallowing, and erectile dysfunction (ED) in males. If you have aHUS, your healthcare provider will need to monitor you closely for at least 12 months after stopping treatment for signs of worsening aHUS or problems related to a type of abnormal clotting and breakdown of your red blood cells called thrombotic microangiopathy (TMA). Symptoms or problems that can happen with TMA may include: confusion or loss of consciousness, seizures, chest pain (angina), difficulty breathing and blood clots or stroke. ULTOMIRIS can cause serious side effects including allergic reactions to acrylic adhesive. Allergic reactions to the acrylic adhesive may happen with your subcutaneous ULTOMIRIS treatment. If you have an allergic reaction during the delivery of subcutaneous ULTOMIRIS, remove the on-body injector and get medical help right away. Your healthcare provider may treat you with medicines to help prevent or treat allergic reaction symptoms as needed. What are the possible side effects of ULTOMIRIS? ULTOMIRIS can cause serious side effects including infusion-related reactions. Symptoms of an infusion-related reaction with ULTOMIRIS may include lower back pain, tiredness, feeling faint, discomfort in your arms or legs, bad taste, or drowsiness. Stop treatment of ULTOMIRIS and tell your healthcare provider or nurse right away if you develop these symptoms, or any other symptoms during your ULTOMIRIS infusion that may mean you are having a serious infusion reaction, including: chest pain, trouble breathing or shortness of breath, swelling of your face, tongue, or throat, and feel faint or pass out. The most common side effects of ULTOMIRIS in people treated for PNH are upper respiratory tract infection and headache. The most common side effects of ULTOMIRIS in people treated for aHUS are upper respiratory tract infection, diarrhea, nausea, vomiting, headache, high blood pressure and fever. The most common side effects of ULTOMIRIS in people with gMG are diarrhea and upper respiratory tract infections. The most common side effects of subcutaneous administration of ULTOMIRIS in adults treated for PNH and aHUS are local injection site reactions. Tell your healthcare provider about any side effect that bothers you or that does not go away. These are not all the possible side effects of ULTOMIRIS. For more information, ask your healthcare provider or pharmacist. Call your healthcare provider right away if you miss an ULTOMIRIS infusion or for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Please see the full Prescribing Information and Medication Guide for SOLIRIS, including Boxed WARNING regarding serious and life-threatening meningococcal infections. Notes PNH PNH is a rare, chronic, progressive and potentially life-threatening blood disorder. It is characterized by red blood cell destruction within blood vessels (also known as intravascular hemolysis) and white blood cell and platelet activation, which can result in thrombosis (blood clots).2-4 PNH is caused by an acquired genetic mutation that may happen any time after birth and results in the production of abnormal blood cells that are missing important protective blood cell surface proteins. These missing proteins enable the complement system, which is part of the immune system and is essential to the body’s defense against infection, to ‘attack’ and destroy or activate these abnormal blood cells.2 Living with PNH can be debilitating, and signs and symptoms may include blood clots, abdominal pain, difficulty swallowing, erectile dysfunction, shortness of breath, excessive fatigue, anemia and dark-colored urine.2,10,14 Clinically Significant EVH EVH, the removal of red blood cells outside of the blood vessels, can sometimes occur in PNH patients who are treated with C5 inhibitors.15,16 Since C5 inhibition enables PNH red blood cells to survive and circulate, EVH may occur when these now surviving PNH red blood cells are marked by proteins in the complement system for removal by the spleen and liver.2,4,6 Patients with PNH with EVH may continue to experience anemia, which can have various causes, and may require blood transfusions.15-18 A small subset of people living with PNH who are treated with a C5 inhibitor experience clinically significant EVH, which can result in continued symptoms of anemia and require blood transfusions.2,10-12 ALPHA ALPHA is a pivotal, global Phase III trial designed as a superiority study to evaluate the efficacy and safety of danicopan as an add-on to C5 inhibitor therapy eculizumab or ravulizumab-cwvz in patients with PNH who experience clinically significant EVH. In the double-blind, placebo-controlled, multiple-dose trial, patients were enrolled and randomized to receive danicopan or placebo (2:1) in addition to their ongoing eculizumab or ravulizumab-cwvz therapy for 12 weeks. A prespecified interim analysis was performed once 63 randomized patients had completed 12 weeks of the primary evaluation period or discontinued treatment as of June 28, 2022. At 12 weeks, patients on placebo plus a C5 inhibitor were switched to danicopan plus eculizumab or ravulizumab-cwvz, and patients on danicopan plus eculizumab or ravulizumab-cwvz remained on treatment for an additional 12 weeks. Patients who completed both treatment periods (24 weeks) had the option to participate in a two-year long-term extension period and continue to receive danicopan in addition to eculizumab or ravulizumab-cwvz. The open-label period of the study is still ongoing.5,19 Danicopan Danicopan is an investigational oral medicine in development as an add-on to C5 inhibitor therapy eculizumab or ravulizumab-cwvz for patients with PNH who experience clinically significant EVH. It is designed to selectively inhibit Factor D, a complement system protein that plays a key role in the amplification of the complement system response. Danicopan has been granted Breakthrough Therapy designation by the US Food and Drug Administration and PRIority MEdicines (PRIME) status by the European Medicines Agency. Danicopan has also been granted Orphan Drug Designation in the US, EU and Japan for the treatment of PNH. Alexion is also evaluating danicopan as a potential monotherapy for geographic atrophy in a Phase II clinical trial. ULTOMIRIS® (ravulizumab-cwvz) ULTOMIRIS® (ravulizumab-cwvz), the first and only long-acting C5 complement inhibitor, provides immediate, complete and sustained complement inhibition. The medication works by inhibiting the C5 protein in the terminal complement cascade, a part of the body’s immune system. When activated in an uncontrolled manner, the complement cascade over-responds, leading the body to attack its own healthy cells. ULTOMIRIS is administered intravenously every eight weeks in adult patients, following a loading dose. ULTOMIRIS is approved in the US, EU and Japan for the treatment of certain adults with generalized myasthenia gravis (gMG). ULTOMIRIS is also approved in the US, EU and Japan for the treatment of certain adults with PNH and for certain children with PNH in the US and EU. Additionally, ULTOMIRIS is approved in the US, EU and Japan for certain adults and children with atypical hemolytic uremic syndrome to inhibit complement-mediated thrombotic microangiopathy (aHUS). Further, ULTOMIRIS is approved in the EU and Japan for the treatment of certain adults with neuromyelitis optica spectrum disorder (NMOSD). As part of a broad development program, ULTOMIRIS is being assessed for the treatment of additional hematology and neurology indications. SOLIRIS® (eculizumab) SOLIRIS® (eculizumab) is a first-in-class C5 complement inhibitor. The medication works by inhibiting the C5 protein in the terminal complement cascade, a part of the body’s immune system. When activated in an uncontrolled manner, the terminal complement cascade over-responds, leading the body to attack its own healthy cells. SOLIRIS is administered intravenously every two weeks, following an introductory dosing period. SOLIRIS is approved in the US, EU, Japan and China for the treatment of patients with PNH and aHUS. Additionally, SOLIRIS is approved in Japan and the EU for the treatment of certain adult and pediatric patients with gMG and in the US and China for certain adults with gMG. Further, SOLIRIS is approved in the US, EU, Japan and China for the treatment of certain adults with NMOSD. SOLIRIS is not indicated for the treatment of patients with Shiga-toxin E. coli-related hemolytic uremic syndrome.
