Serious infections have happened while taking RINVOQ, including tuberculosis (TB) and infections caused by bacteria, fungi, or viruses that can spread throughout the body. Some people have died from these infections. Your healthcare provider (HCP) should test you for TB before starting RINVOQ and check you closely for signs and symptoms of TB during treatment with RINVOQ. You should not start taking RINVOQ if you have any kind of infection unless your HCP tells you it is okay. If you get a serious infection, your HCP may stop your treatment until your infection is controlled. You may be at higher risk of developing shingles (herpes zoster). Increased risk of death in people 50 years and older who have at least 1 heart disease (cardiovascular) risk factor. Cancer and immune system problems. RINVOQ may increase your risk of certain cancers. Lymphoma and other cancers, including skin cancers, can happen.

(Nasdaq: KNSA) (Kiniksa), a commercial-stage biopharmaceutical company with a pipeline of immune-modulating assets designed to target a spectrum of cardiovascular and autoimmune diseases, today reported fourth quarter and full-year 2023 financial results and recent portfolio execution. “Kiniksa meaningfully advanced its business in 2023, primarily through robust ARCALYST net product revenue and collaboration profit growth. Significant growth remains with ARCALYST in recurrent pericarditis, and we expect to help an increasing number of patients in the years ahead. Importantly, we anticipate our robust commercial performance to contribute to our strong financial position and ability to drive growth across our business,” said Sanj K. Patel, Chairman and Chief Executive Officer of Kiniksa. “Additionally, abiprubart recently showed clinical effect in the first three cohorts of the Phase 2 trial in rheumatoid arthritis. We now expect to advance the asset into a Phase 2b trial in a new indication, funding for which is included in our current cash runway guidance. Data from the fourth cohort of the abiprubart Phase 2 trial are intended to inform trial design and are expected in April.” Portfolio and Collaboration Execution ARCALYST (IL-1α and IL-1β cytokine trap) ARCALYST net product revenue was $71.2 million and $233.2 million for the fourth quarter and full-year 2023, respectively. Since launch in April 2021, more than 1,700 prescribers have written ARCALYST prescriptions for recurrent pericarditis. As of the end of the fourth quarter of 2023, average total duration of ARCALYST therapy in recurrent pericarditis had increased to approximately 23 months. As of the end of the fourth quarter of 2023, approximately 9% of the target 14,000 multiple-recurrence patients were actively on ARCALYST treatment. A poster entitled Rilonacept Utilization in a Steroid-Sparing Paradigm for Recurrent Pericarditis: Real-World Evidence Demonstrating Increased Adoption is planned to be presented at the upcoming American College of Cardiology Scientific Session (ACC.24) in April 2024. Abiprubart (anti-CD40 monoclonal antibody inhibitor of CD40-CD154 interaction) Kiniksa previously announced topline data from the Phase 2 clinical trial of abiprubart in rheumatoid arthritis, showing that the trial met its primary efficacy endpoint: change from baseline in Disease Activity Score of 28 Joints Using C-reactive Protein (DAS28-CRP) versus placebo. In Cohorts 1 and 2 (pharmacokinetic lead-in), multiple doses of abiprubart were well-tolerated. In Cohort 3, the abiprubart 5 mg/kg subcutaneous (SC) weekly dose level achieved statistical significance. The 5 mg/kg SC biweekly dose level did not achieve statistical significance. Across both dose levels abiprubart reduced Rheumatoid Factor, a clinical marker of disease activity and an autoantibody pharmacodynamic marker of CD40 target engagement. Abiprubart was well-tolerated, with no dose-related adverse experiences observed. Kiniksa expects data from the fourth cohort (Cohort 4) of the Phase 2 clinical trial in April 2024. Cohort 4 will evaluate a fixed dose level administered as a single subcutaneous injection once monthly. Mavrilimumab (monoclonal antibody inhibitor targeting GM-CSFRα) Kiniksa is evaluating potential partnership opportunities to advance development of mavrilimumab, which has generated positive data in mid-stage clinical trials across multiple indications. Vixarelimab (monoclonal antibody inhibitor of signaling through OSMRβ) In the fourth quarter of 2023, Kiniksa recognized a $10.0 million development milestone related to a second new indication under its global license agreement with Genentech, a member of the Roche Group. Financial Results Total revenue for the fourth quarter of 2023 was $83.4 million, compared to $61.9 million for the fourth quarter of 2022. Total revenue for the full-year 2023 was $270.3 million, compared to $220.2 million for the full-year 2022. Total revenue for the fourth quarter of 2023 included $12.2 million in license and collaboration revenue, compared to $21.9 million for the fourth quarter of 2022. Total revenue for the full-year 2023 included $37.1 million in license and collaboration revenue, compared to $97.7 million for the full-year 2022. Total operating expenses for the fourth quarter of 2023 were $83.3 million, compared to $55.8 million for the fourth quarter of 2022. Total operating expenses for the full-year 2023 were $295.5 million, compared to $210.4 million for the full-year 2022. Total operating expenses for the fourth quarter of 2023 included $16.9 million in collaboration expenses, which are driven by ARCALYST collaboration profitability, compared to $7.5 million for the fourth quarter of 2022. Total operating expenses for the full-year 2023 included $56.5 million in collaboration expenses, compared to $24.1 million for the full-year 2022. Total operating expenses for the fourth quarter of 2023 included $7.8 million in non-cash, share-based compensation expense, compared to $6.4 million for the fourth quarter of 2022. Total operating expense for the full-year 2023 included $27.1 million in non-cash, share-based compensation expense, compared to $25.1 million for the full-year 2022. Net income for the fourth quarter of 2023 was $25.2 million, compared to net income of $4.5 million for the fourth quarter of 2022. Net income for the full-year 2023 was $14.1 million, compared to net income of $183.4 million for the full-year 2022. Net income for the fourth quarter of 2023 included a tax benefit of $22.8 million, primarily due to the treatment of non-cash deferred tax assets, compared to a tax expense of $2.4 million for the fourth quarter of 2022. Net income for the full-year 2023 included a tax benefit of $30.7 million, compared to a tax benefit of $172.3 million for the full-year 2022, both primarily due to the treatment of non-cash deferred tax assets. As of December 31, 2023, Kiniksa had $206.4 million of cash, cash equivalents, and short-term investments and no debt. Financial Guidance Kiniksa expects 2024 ARCALYST net product revenue of between $360 million and $380 million. Kiniksa expects that its cash, cash equivalents, and short-term investments will fund its current operating plan into at least 2027.

About ARCALYST ARCALYST is a weekly, subcutaneously injected recombinant dimeric fusion protein that blocks interleukin-1 alpha (IL-1α) and interleukin-1 beta (IL-1β) signaling. ARCALYST was discovered by Regeneron Pharmaceuticals, Inc. (Regeneron) and is approved by the U.S. Food and Drug Administration (FDA) for recurrent pericarditis, cryopyrin-associated periodic syndromes (CAPS), including Familial Cold Autoinflammatory Syndrome and Muckle-Wells Syndrome, and deficiency of IL-1 receptor antagonist (DIRA). The FDA granted Breakthrough Therapy designation to ARCALYST for the treatment of recurrent pericarditis in 2019 and Orphan Drug exclusivity to ARCALYST in 2021 for the treatment of recurrent pericarditis and reduction in risk of recurrence in adults and pediatric patients 12 years and older. The European Commission granted Orphan Drug Designation to ARCALYST for the treatment of idiopathic pericarditis in 2021. IMPORTANT SAFETY INFORMATION ABOUT ARCALYST ARCALYST may affect your immune system and can lower the ability of your immune system to fight infections. Serious infections, including life-threatening infections and death, have happened in patients taking ARCALYST. If you have any signs of an infection, call your doctor right away. Treatment with ARCALYST should be stopped if you get a serious infection. You should not begin treatment with ARCALYST if you have an infection or have infections that keep coming back (chronic infection). While taking ARCALYST, do not take other medicines that block interleukin-1, such as Kineret® (anakinra), or medicines that block tumor necrosis factor, such as Enbrel® (etanercept), Humira® (adalimumab), or Remicade® (infliximab), as this may increase your risk of getting a serious infection. Talk with your doctor about your vaccine history. Ask your doctor whether you should receive any vaccines before you begin treatment with ARCALYST. Medicines that affect the immune system may increase the risk of getting cancer. Stop taking ARCALYST and call your doctor or get emergency care right away if you have any symptoms of an allergic reaction. Your doctor will do blood tests to check for changes in your blood cholesterol and triglycerides. Common side effects include injection-site reactions (which may include pain, redness, swelling, itching, bruising, lumps, inflammation, skin rash, blisters, warmth, and bleeding at the injection site), upper respiratory tract infections, joint and muscle aches, rash, ear infection, sore throat, and runny nose. For more information about ARCALYST, talk to your doctor and see the Product Information. About Abiprubart Abiprubart is an investigational humanized monoclonal antibody that binds to CD40 and is designed to inhibit the CD40-CD154 (CD40 ligand) interaction, a key T-cell co-stimulatory signal critical for B-cell maturation and immunoglobulin class switching and Type 1 immune responses. Kiniksa believes disrupting the CD40-CD154 co-stimulatory interaction is an attractive approach to addressing multiple autoimmune disease pathologies. About Mavrilimumab Mavrilimumab is an investigational fully human monoclonal antibody that blocks activity of GM-CSF by specifically binding to the alpha subunit of the GM-CSF receptor (GM-CSFRα). Phase 2 clinical trials of mavrilimumab in rheumatoid arthritis and giant cell arteritis achieved their primary and secondary endpoints with statistical significance. Kiniksa is evaluating potential partnership opportunities for mavrilimumab.

Phase 2 data in adults with hidradenitis suppurativa (HS) who had previously failed anti-TNF therapy who received lutikizumab (ABT-981) 300 mg weekly or 300 mg every other week showed higher response rates in HiSCR 50 at week 16 than those treated with placebo1,2 Higher response rates were also observed in patients receiving lutikizumab 300 mg weekly or 300 mg every other week than those treated with placebo in the secondary endpoint of skin pain NRS30 at week 16 among patients with baseline NRS≥31,2 HS is a chronic, often debilitating inflammatory skin disease that can form lumps, abscesses and scars under the arms, in the groin and other areas3,4,5,6,7 Program reflects AbbVie's leadership in immunology and history of investigating new options for patients with HS, where there remains a significant unmet medical need NORTH CHICAGO, Ill., Jan. 8, 2024 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced Phase 2 results showing adults with moderate to severe hidradenitis suppurativa (HS) who had previously failed anti-TNF therapy who received lutikizumab (ABT-981) 300 mg every other week or 300 mg weekly achieved higher response rates (59.5 percent, nominal p=0.027 and 48.7 percent, nominal p=0.197, respectively) than placebo (35.0 percent) in the primary endpoint of achieving HS Clinical Response (HiSCR 50) at week 16. Based on these data, AbbVie will advance its clinical program of lutikizumab in HS to Phase 3.1,2 Lutikizumab is AbbVie's investigational, dual-variable-domain interleukin (IL) 1α/1β antagonist. Studies have shown IL 1α and 1β are elevated in HS lesions.8 "AbbVie continues to pioneer research in the pursuit of new treatment options for patients with hidradenitis suppurativa, a frequently overlooked, underserved, and often suffering patient population," said Roopal Thakkar, M.D., senior vice president, chief medical officer, global therapeutics, AbbVie. "These results help us further understand the use of lutikizumab in adults with moderate to severe hidradenitis suppurativa, and we will continue to apply our more than 25 years of expertise in immune-mediated diseases in advancing our clinical program for lutikizumab in HS to Phase 3." This study was a 16-week, Phase 2, randomized, double-blind, parallel group, placebo controlled, dose-ranging, multicenter study that evaluated the safety and efficacy of lutikizumab in 153 adult patients with moderate to severe HS who had previously failed anti-TNF therapy. Most patients (70.6 percent) had severe baseline Hurley Stage 3 disease – the most extensive form of HS – characterized by scarring, lesions and sinus tracts. Patients were randomized at baseline to receive one of three subcutaneous doses of lutikizumab (100 mg every other week, 300 mg every other week, or 300 mg every week) or placebo. The study's primary endpoint was an achievement of HiSCR 50 at week 16, and the secondary endpoint was skin pain NRS30 at week 16 among subjects with baseline NRS≥3.1 In addition to achieving higher response rates in the primary endpoint and despite most patients having severe disease, the trial also showed patients receiving lutikizumab 300 mg weekly and 300 mg every other week achieved higher rates of improved skin pain via NRS30 and HiSCR75, a higher threshold of HS clinical response, compared to placebo. Lutikizumab 100 mg every other week did not show greater efficacy compared to placebo.1 Results from select endpoints are as follows: All doses were generally well-tolerated. The percentage of subjects with treatment-emergent adverse events (TEAE) were generally similar across combined lutikizumab treatment arms (70.8 percent) and placebo (75.0 percent) with the most common being HS (10.6 percent), diarrhea (8.8 percent), headache (8.8 percent), pruritus (6.2 percent), contact dermatitis (5.3 percent), eczema (5.3 percent), and nasopharyngitis (5.3 percent) in the combined lutikizumab treatment group. Serious adverse events (SAEs) occurred in 5.3 percent of the combined lutikizumab treatment group and in 2.5 percent in the placebo group. There were no deaths, no events of neutropenia reported, and no Grade 3 or 4 laboratory evaluations of neutropenia observed. Throughout the study, one event of serious infection (infected stoma) was reported in lutikizumab 300 mg every other week, with no associated neutropenia, deemed by the investigator as having no reasonable possibility of being related to study drug. There was one instance of T-cell lymphoma (lutikizumab 300 mg every week) reported in a patient with pre-existing risk factors, including HS9 and ongoing cigarette smoking. There were no dose-dependent trends in any TEAEs, SAEs, infections, or serious infections. "The burdens of HS are high and include long times to diagnosis, significant pain, disability, isolation, and reduced quality of life," said Alexa B. Kimball, M.D., MPH, a study investigator from Beth Israel Deaconess Medical Center in Boston and Professor of Dermatology, Harvard Medical School.10,11,12 "These results are encouraging and help us further understand the use of lutikizumab in patients with HS as we work to address the need for additional treatment options for patients living with this disease." HiSCR 50 at week 16, the primary endpoint of this study, is a measure that represents patients who achieve at least a 50 percent reduction at week 16 in the total abscess and inflammatory nodule (AN) count with no increase in abscess count and no increase in draining fistula count relative to baseline. Similarly, HiSCR 75 represents the achievement of at least a 75 percent reduction in AN count at week 16 with no increase in draining fistula count relative to baseline. The secondary endpoint, NRS30 at week 16, defines the achievement of at least a 30 percent reduction and at least 1-unit reduction from baseline in NRS (Numeric Rating Scale) at week 16 as assessed by patient global assessment for skin pain, among subjects with baseline NRS≥3.13 These data will be presented at a future medical congress. Additional information about the program can be found on clinicaltrials.gov under the identifier NCT05139602.2 About Hidradenitis Suppurativa Hidradenitis Suppurativa, sometimes referred to as "acne inversa" by dermatologists, is an inflammatory, chronic, recurrent, progressive disease that causes irreversible skin damage and disability due to the formation of painful cysts, abscesses and draining fistula.3,4,5,6,7 While advances in treatment have been made, limited treatment options are available. Globally, HS affects up to 1 percent of the population14 and can take on average 7-10 years for a person to be diagnosed.15,16 About Lutikizumab (ABT-981) Lutikizumab (ABT-981) is a dual-variable-domain interleukin (IL) 1α/1β antagonist being investigated in several immune-mediated diseases, including HS and ulcerative colitis. Studies have shown IL 1α and 1β are elevated in HS lesions.8 Lutikizumab is an investigational agent and is not approved by regulatory authorities. Safety and efficacy have not been established.
