“Continued solid execution through the third quarter positions us to deliver multiple near-term milestones,” said
Third Quarter 2018 and Recent Pipeline Progress
Rilonacept (IL-1α and IL-1β cytokine trap)
- Kiniksa plans to initiate a single, pivotal, placebo-controlled, randomized-withdrawal design, global Phase 3 clinical trial of rilonacept in approximately 60 subjects with symptomatic recurrent pericarditis later this year.
- Kiniksa continues to enroll subjects into the rilonacept open-label Phase 2 proof-of-concept clinical trial in order to gain further experience with rilonacept in different pericarditis populations. The response to treatment continues to be consistent with the first subjects who entered the trial in terms of rapid reduction in reported pain and inflammation. Kiniksa plans to report additional open-label Phase 2 proof-of-concept clinical trial data and close enrollment in the trial later this year.
Mavrilimumab (monoclonal antibody inhibitor targeting GM-CSFRα)
- Kiniksa completed its pre-investigational new drug application (IND) meeting with the
U.S. Food and Drug Administration( FDA) and believes its Phase 2 clinical trial development plan for mavrilimumab in giant cell arteritis (GCA) is consistent with the feedback it received from the FDA.
- The double-blind, randomized, placebo-controlled, global Phase 2 proof-of-concept clinical trial of mavrilimumab for the treatment of GCA will enroll approximately 60 subjects with new-onset and refractory disease. Subjects will be randomized 3:2 to mavrilimumab 150 mg or placebo injected subcutaneously once every 2 weeks co-administered with a corticosteroid taper. Treatment duration will be 26 weeks. The primary efficacy endpoint will be time to first flare.
KPL-716 (monoclonal antibody inhibitor of signaling through OSMRβ)
- Kiniksa plans to advance KPL-716 into multiple chronic pruritic diseases, starting with an adaptive design Phase 2a/2b clinical trial in prurigo nodularis, in the first quarter of 2019.
- Kiniksa announced Phase 1a/1b clinical data for KPL-716. In this First-in-Human clinical trial, single intravenous (IV) and subcutaneous (SC) doses of KPL-716 were well-tolerated in both adult healthy volunteers and adult subjects with moderate-to-severe atopic dermatitis experiencing moderate-to-severe pruritus. Additionally, a single dose of KPL-716 7.5 mg/kg IV (n=10) versus placebo IV (n=10) provided evidence of target engagement and an early signal of efficacy in reducing pruritus as well as inflammation and disease severity in subjects with moderate-to-severe atopic dermatitis. Preliminary pharmacokinetic modeling supports testing once every 2 weeks and once-monthly SC dosing regimens in a Phase 2b.
- Kiniksa continues to enroll a repeated-single-dose cohort as an additional part of the Phase 1b clinical trial in the U.S. and
Canada. In this double-blind, randomized, placebo-controlled study, approximately 50 subjects with moderate-to-severe atopic dermatitis experiencing moderate-to-severe pruritus receive KPL-716 360 mg or placebo via SC injection once weekly for 12 weeks. The study is designed to evaluate safety and chronic efficacy data on both pruritus and inflammatory disease response markers by providing similar and longer-term exposures compared to the single-dose IV cohort of the Phase 1b clinical trial. Results are expected in the second half of 2019.
KPL-045 (monoclonal antibody inhibitor of the CD30L co-stimulatory molecule)
- Kiniksa continues its preclinical activities with KPL-045 in inflammatory diseases driven by T-cell-dependent autoantibody generation and dysregulated TH effector memory responses and expects to file an IND application with the
FDAin the second half of 2019.
KPL-404 (monoclonal antibody inhibitor of the CD40 co-stimulatory receptor)
- Kiniksa continues its preclinical activities with KPL-404 in T-cell-dependent, B-cell-mediated disorders and expects to file an IND application with the
FDAin the second half of 2019.

Rilonacept is a weekly, subcutaneously-injected, recombinant fusion protein that blocks IL-1α and IL-1β signaling. Rilonacept was approved by the
Mavrilimumab is an investigational fully-human monoclonal antibody that antagonizes GM-CSF signaling by binding to the alpha subunit of the GM-CSF receptor. Kiniksa’s lead indication for mavrilimumab is giant cell arteritis, an inflammatory disease of blood vessels.
KPL-716 is an investigational fully-human monoclonal antibody that targets oncostatin M receptor beta (OSMRβ), which mediates signaling of IL-31 and oncostatin M (OSM), two key cytokines implicated in pruritus, inflammation and fibrosis. Kiniksa believes KPL-716 to be the only monoclonal antibody in development that targets both pathways simultaneously.
KPL-045 is an investigational fully-human monoclonal antibody that is designed to inhibit the CD30-CD30 ligand interaction, a co-stimulatory signal involved in activating and sustaining memory T-cells.
KPL-404 is an investigational humanized monoclonal antibody that is designed to inhibit the CD40-CD40 ligand interaction, a key T-cell co-stimulatory signal critical for B-cell maturation and immunoglobulin class switching. Kiniksa obtained a license to conduct research and development on KPL-404 from
