HAMILTON, Bermuda, Nov. 01, 2021 (GLOBE NEWSWIRE) -- 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 2021 financial results and recent portfolio execution.
“We are delighted with the ARCALYST launch performance in recurrent pericarditis. The continued momentum underscores the dedication of our first-rate team as well as the unmet need for patients with this debilitating disease,” said Sanj K. Patel, Chairman and Chief Executive Officer of Kiniksa. “In addition to our ongoing commercial efforts, we are executing on our clinical-stage pipeline. Mavrilimumab demonstrated potentially best-in-class mortality reduction in a Phase 2 study in non-mechanically ventilated patients with COVID-19-related ARDS, and Phase 3 data are on track for the first quarter of 2022. We are also conducting a dose-ranging Phase 2b study of vixarelimab in prurigo nodularis with data expected in the second half of 2022. Furthermore, we expect to initiate a Phase 2 proof-of-concept trial of KPL-404 in rheumatoid arthritis by the end of 2021.”
ARCALYST (IL-1α and IL-1β cytokine trap)
- ARCALYST net revenue for the third quarter of 2021 was $12.1 million.
- More than 200 physicians have prescribed ARCALYST for recurrent pericarditis since approval.
- More than 90% of completed patient enrollment cases for recurrent pericarditis were approved for coverage.
- Kiniksa has achieved broad access for its recurrent pericarditis target population in the United States, with greater than 190 million lives receiving favorable coverage.
- Two thirds of ARCALYST prescriptions for recurrent pericarditis have been written for 12 months of therapy.
- Recent data from the ongoing Phase 3 clinical trial of ARCALYST in recurrent pericarditis (RHAPSODY) showed median duration of continuous ARCALYST therapy at the 1-year anniversary of the Long-Term Extension portion of the trial of approximately 20 months.
Mavrilimumab (monoclonal antibody inhibitor targeting GM-CSFRα)
- Mavrilimumab has demonstrated broad utility across multiple indications including COVID-19-related acute respiratory distress syndrome (ARDS) and giant cell arteritis (GCA).
- Kiniksa expects data from the Phase 3 clinical trial of mavrilimumab in hospitalized non-mechanically ventilated patients with COVID-19-related ARDS in the first quarter of 2022.
- The primary efficacy endpoint for the Phase 3 trial is the proportion of patients alive and without mechanical ventilation at Day 29. A key secondary efficacy endpoint is mortality at Day 29.
- Phase 2 clinical data in hospitalized non-mechanically ventilated patients with COVID-19-related ARDS showed mavrilimumab reduced the risk of mechanical ventilation or death by 65% versus placebo at Day 29.
Vixarelimab (monoclonal antibody inhibitor of signaling through OSMRβ)
- Kiniksa expects data from the dose-ranging Phase 2b clinical trial of vixarelimab in prurigo nodularis in the second half of 2022.

ARCALYST is a weekly, subcutaneously injected recombinant dimeric fusion protein that blocks interleukin-1 alpha and interleukin-1 beta signaling. ARCALYST was discovered by Regeneron and is approved by the 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.
Important Information About ARCALYST Injection
- ARCALYST can 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. You should not begin ARCALYST if you have an infection or have infections that keep coming back. After starting ARCALYST, if you get an infection or show any sign of an infection, including a fever, cough, flu-like symptoms, or have any open sores on your body, call your doctor right away. Treatment with ARCALYST should be stopped if you get a serious 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.
- Before starting ARCALYST, tell your doctor if you think you have an infection, are being treated for an infection, have signs of an infection, have any open sores, have a history of infections that keep coming back, have asthma, have diabetes or an immune system problem, have tuberculosis, or have been in contact with someone who has had tuberculosis, has or has had HIV, hepatitis B or hepatitis C, or takes other medicines that affect your immune system.
- Before you begin treatment with ARCALYST, talk with your healthcare provider about your vaccine history. Ask your healthcare provider whether you should receive any vaccines, including the pneumonia vaccine and flu vaccine, before you begin treatment with ARCALYST.
- ARCALYST can cause serious side effects:
- 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 (e.g., rash, swollen face, trouble breathing).
- Your doctor will do blood tests to check for changes in your blood cholesterol and triglycerides.
- Common side effects of ARCALYST include injection-site reactions, upper respiratory tract infections, joint and muscle aches, rash, ear infection, sore throat, and runny nose.
- Tell your doctor if you are scheduled to receive any vaccines, if you are pregnant or plan to become pregnant, and if you are breastfeeding or plan to breastfeed.
- Tell your doctor if you take other medicines that affect the immune system such as interleukin-1 blockers, tumor necrosis factor blockers, or corticosteroids.
- For more information about ARCALYST, talk to your doctor and see the Product Information.
Mavrilimumab is an investigational fully human monoclonal antibody that blocks activity of granulocyte macrophage colony stimulating factor (GM-CSF) by specifically binding to the alpha subunit of the GM-CSF receptor. Mavrilimumab was dosed in over 550 patients with rheumatoid arthritis through Phase 2b clinical studies in Europe and achieved prospectively defined primary endpoints of efficacy and safety. Kiniksa is evaluating mavrilimumab in GCA, and the Phase 2 clinical trial achieved both the primary and secondary efficacy endpoints with statistical significance. Kiniksa continues to evaluate mavrilimumab in COVID-19-related ARDS. The FDA granted Orphan Drug designation to mavrilimumab for the treatment of GCA in 2020.
Vixarelimab is an investigational fully human monoclonal antibody that targets oncostatin M receptor beta (OSMRβ), which mediates signaling of interleukin-31 (IL-31) and oncostatin M (OSM), two key cytokines implicated in pruritus, inflammation, and fibrosis. Kiniksa believes vixarelimab to be the only monoclonal antibody in development that targets both pathways simultaneously. Kiniksa’s lead indication for vixarelimab is prurigo nodularis, a chronic inflammatory skin condition characterized by severely pruritic skin nodules. The FDA granted Breakthrough Therapy designation to vixarelimab for the treatment of pruritus associated with prurigo nodularis in 2020.
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. Kiniksa owns or controls the intellectual property related to KPL-404.
