HAMILTON, BERMUDA – November 1, 2022 – Kiniksa Pharmaceuticals, Ltd. (Nasdaq: KNSA) (Kiniksa), a biopharmaceutical company with a portfolio of assets designed to modulate immunological pathways across a spectrum of diseases, today reported third quarter 2022 financial results and provided a corporate update.
“Physician adoption, patient satisfaction, and payer access drove continued strong ARCALYST performance in the third quarter. We remain focused on positioning ARCALYST as the standard of care for recurrent pericarditis, with the goal of broadening our reach and helping even more patients,” said Sanj K. Patel, Chairman and Chief Executive Officer of Kiniksa. “Additionally, with the profitable ARCALYST collaboration and initial proceeds from the global license agreement with Genentech for the rights to develop and commercialize vixarelimab, we are well-positioned to execute on synergistic growth opportunities across our portfolio, including the expansion of our ARCALYST cardiovascular franchise.”
Corporate Update
| · | In September 2022, Kiniksa announced the closing of its global license agreement with Roche and Genentech, a member of the Roche Group (Genentech), for the rights to develop and commercialize vixarelimab in exchange for $100 million in upfront and near-term payments, approximately $600 million in clinical, regulatory, and sales-based milestones before fulfilling upstream obligations, and royalties on annual net sales. |
Portfolio Execution
ARCALYST (IL-1α and IL-1β cytokine trap)
| · | ARCALYST net revenue was $33.4 million for the third quarter of 2022. |
| - | Greater than 650 prescribers have written ARCALYST prescriptions for recurrent pericarditis since launch. |
| 1 |
| · | Greater than 90% payer approval rate of completed patient cases for recurrent pericarditis in the third quarter of 2022. |
| · | As of the end of the third quarter of 2022, the average duration of initial therapy in the commercial setting was approximately 12 months, and approximately 35% of recurrent pericarditis patients who had discontinued ARCALYST therapy restarted treatment. |
KPL-404 (monoclonal antibody inhibitor of CD40-CD154 interaction)
| · | Kiniksa is enrolling the second and final cohort of the multiple ascending dose portion of the Phase 2 clinical trial of KPL-404 in rheumatoid arthritis.

Mavrilimumab (monoclonal antibody inhibitor targeting GM-CSFRα)
| · | Kiniksa is pursuing collaborative study agreements to evaluate the potential of mavrilimumab in rare cardiovascular diseases where the granulocyte macrophage colony stimulating factor (GM-CSF) mechanism has been implicated. |
Upcoming Scientific Conference Presentation
| · | Kiniksa today announced that an abstract highlighting long-term extension (LTE) data from RHAPSODY, the pivotal Phase 3 clinical trial of rilonacept in recurrent pericarditis, has been accepted for presentation at the American Heart Association (AHA) Scientific Sessions 2022.1,2 |
| · | LTE data included in the abstract demonstrated rilonacept treatment beyond 18 months resulted in continued treatment response. |
| - | The median [maximum at end of LTE] duration of continuous rilonacept therapy for all patients in RHAPSODY was 18 [27] months for US patients (n=45) and 27 [33] months for non-US patients (n=29).3 |
| - | The annualized incidence of pericarditis recurrences while on therapy for all patients (n=74) during the first 18 months of the LTE portion of the trial was 0.04 events per patient-year. |
| - | Patients were given the option at 18 months from their most recent pericarditis recurrence to continue or suspend rilonacept treatment for observation. |
1 Dr. Massimo Imazio of University Hospital Santa Maria della Misericordia, Udine, will present a poster presentation entitled Prolonged Rilonacept Treatment in RHAPSODY Long-Term Extension Provided Persistent Reduction of Pericarditis Recurrence Risk on Sunday, November 6, 2022, from 3:45 to 4:45 p.m. Central Time (4:45 – 5:45 p.m. Eastern Time).
2 Data in the abstract are as of the abstract cutoff date; final data are under embargo until the poster presentation.
3 Upon commercial availability of ARCALYST for recurrent pericarditis in April 2021, the LTE portion in the US ended, and patients continuing therapy transitioned to commercial ARCALYST. Non-US patients remained in the LTE without interruption until the LTE closed in June 2022.

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 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 designation to ARCALYST for the treatment of pericarditis in 2020. The European Commission granted Orphan Drug Designation to ARCALYST for the treatment of idiopathic pericarditis in 2020.
ARCALYST is indicated for:
| · | Treatment of Recurrent Pericarditis (RP) and reduction in risk of recurrence in adults and pediatric patients 12 years and older. |
| · | Treatment of Cryopyrin-Associated Periodic Syndromes (CAPS), including Familial Cold Auto-inflammatory Syndrome (FCAS), and Muckle-Wells Syndrome (MWS) in adults and children 12 years and older. |
| · | Maintenance of remission of Deficiency of Interleukin-1 Receptor Antagonist (DIRA) in adults and pediatric patients weighing 10 kg or more. |
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. |
| 4 |
| · | 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 KPL-404
KPL-404 is an investigational humanized monoclonal antibody that is designed to inhibit 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 interaction is an attractive approach to address 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 the development of mavrilimumab in rare cardiovascular diseases where the GM-CSF mechanism has been implicated.
