HAMILTON, Bermuda, Jan. 10, 2022 (GLOBE NEWSWIRE) -- Kiniksa Pharmaceuticals, Ltd. (Nasdaq: KNSA) (Kiniksa), a biopharmaceutical company with a pipeline of assets designed to modulate immunological pathways across a spectrum of diseases, today provided a corporate update and announced anticipated milestones for 2022.

“2021 was a transformational year for Kiniksa. We progressed to a commercial-stage company with the successful launch of ARCALYST for the treatment of recurrent pericarditis. We are pleased with the strong physician and patient adoption and expect to provide annual guidance along with fourth quarter and full-year 2021 financial results,” said Sanj K. Patel, Chairman and Chief Executive Officer of Kiniksa. “This year, we look forward to continued commercial excellence with ARCALYST, as well as reporting data from the Phase 2b trial of vixarelimab in prurigo nodularis, and conducting the Phase 2 trial of KPL-404 in rheumatoid arthritis.”

Corporate Update

  • Kiniksa’s resources are currently focused on growing the ARCALYST franchise and progressing the clinical trials of vixarelimab in prurigo nodularis and KPL-404 in rheumatoid arthritis.
  • Kiniksa’s year-end 2021 cash, cash equivalents and short-term investments of approximately $182 million (unaudited) are expected to fund its current operating plan into 2024.

Portfolio Update
ARCALYST (IL-1α and IL-1β cytokine trap)

  • Kiniksa expects to provide full-year 2022 ARCALYST net revenue guidance with its fourth quarter and full-year 2021 financial results.

Mavrilimumab (monoclonal antibody inhibitor targeting GM-CSFRα)

  • As previously reported, the Phase 3 portion of the Phase 2/3 trial of mavrilimumab in COVID-19-related acute respiratory distress syndrome (ARDS) did not meet its primary efficacy endpoint of the proportion of patients alive and free of mechanical ventilation at Day 29.
  • Kiniksa continues to believe in the potential broad utility of mavrilimumab and is evaluating next steps for the molecule.

Vixarelimab (monoclonal antibody inhibitor of signaling through OSMRβ)

  • Kiniksa expects data from the Phase 2b dose-ranging clinical trial of once-monthly subcutaneous vixarelimab in prurigo nodularis in the second half of 2022.

KPL-404 (monoclonal antibody inhibitor of CD40-CD154 signaling)

  • Kiniksa is enrolling and dosing patients in a Phase 2 clinical trial of KPL-404 in rheumatoid arthritis which is designed to enable potential development in a spectrum of autoimmune diseases believed to be mediated by the CD40-CD154 pathway.

40th Annual J.P. Morgan Healthcare Conference

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.

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 Mavrilimumab
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 previously evaluated in rheumatoid arthritis through Phase 2b clinical studies in Europe and achieved prospectively defined primary endpoints of efficacy and safety. Kiniksa is evaluating next steps for mavrilimumab in giant cell arteritis (GCA). The Phase 2 clinical trial of mavrilimumab in GCA achieved both the primary and secondary efficacy endpoints with statistical significance. The FDA granted Orphan Drug designation to mavrilimumab for the treatment of GCA in 2020.

About Vixarelimab
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.

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. Kiniksa owns or controls the intellectual property related to KPL-404.
