Clinical-Stage Pipeline Activity
Rilonacept (IL-1α and IL-1β cytokine trap)
- Kiniksa is advancing rilonacept for the potential treatment of recurrent pericarditis, a painful autoinflammatory cardiovascular disease with an estimated U.S. prevalent population of approximately 40,000 patients seeking and receiving medical treatment.
º Kiniksa is enrolling RHAPSODY, a double-blind, placebo-controlled, randomized-withdrawal (RW) design, global Phase 3 clinical trial of rilonacept in subjects with recurrent pericarditis. The primary efficacy endpoint is time-to-first-pericarditis-recurrence in the RW period. Top-line data are expected in the second half of 2020.
December 2018, Kiniksa completed enrollment in an open-label Phase 2 clinical trial of rilonacept in subjects with recurrent pericarditis and announced interim data. As of the November 2018data cutoff date, 12 symptomatic subjects participating in one portion of the Phase 2 trial showed a reduction in both C-reactive protein (CRP) and reported pain. Ten of the subjects had completed the 6-week base treatment period and entered into the optional 18-week extension period. Four of the 10 subjects had completed the optional 18-week extension period. All subjects showed a persistent clinical response as measured by CRP and pain levels at each measurement point during the study.
º Kiniksa plans to present additional interim data from the open-label Phase 2 clinical trial of rilonacept in subjects with recurrent pericarditis at the
American Collegeof Cardiology’s 68th Annual Scientific Session in March 2019.
Mavrilimumab (monoclonal antibody inhibitor targeting GM-CSFRα)
- Kiniksa announced an active investigational new drug (IND) application and is advancing mavrilimumab for the potential treatment of giant cell arteritis (GCA), a chronic inflammatory disease of medium-large blood vessels with an estimated U.S. prevalence of approximately 75,000 to 150,000 patients.
º Kiniksa is enrolling a randomized, double-blind, placebo-controlled, global Phase 2 proof-of-concept clinical trial of mavrilimumab in subjects with GCA. The primary efficacy endpoint is time-to-first-flare. Top-line data are expected in the second half of 2020.
KPL-716 (monoclonal antibody inhibitor of signaling through OSMRβ)
- Kiniksa is advancing KPL-716 for the potential treatment of a variety of pruritic diseases, including prurigo nodularis, a chronic inflammatory skin condition with an estimated U.S. prevalence of approximately 300,000 patients.
º Kiniksa plans to initiate a randomized, double-blind, placebo-controlled, adaptive design Phase 2a/2b clinical trial of KPL-716 in subjects with prurigo nodularis in the first half of 2019. The primary efficacy endpoint of the Phase 2a cohort is percent change from baseline in weekly average Worst-Itch Numeric Rating Scale (WI-NRS). Phase 2a top-line data are expected in the first half of 2020.
º Kiniksa plans to initiate an exploratory, multi-indication, randomized, double-blind, placebo-controlled, Phase 2 pilot clinical trial in a number of diseases characterized by chronic pruritus in the first half of 2019. The exploratory study is designed to identify chronic pruritic conditions where interleukin-31 (IL-31) and/or oncostatin M (OSM) may be playing a role and to investigate the efficacy, safety and tolerability of KPL-716 in reducing the moderate-to-severe pruritus experienced by these subjects. Kiniksa expects the study cohorts to be chronic idiopathic urticaria, chronic idiopathic pruritus, plaque psoriasis, lichen planus and lichen simplex chronicus. Each cohort will be an independent sub-study. Top-line data are expected in the second half of 2020.
º Kiniksa is enrolling a randomized, double-blind, placebo-controlled, repeated-single-dose Phase 1b clinical trial of KPL-716 in subjects with moderate-to-severe atopic dermatitis experiencing moderate-to-severe pruritus. Top-line data are expected in the second half of 2019.
- Kiniksa plans to present four abstracts at the
Society for Investigational Dermatologyin May 2019.
Preclinical Pipeline Activity
- Kiniksa continues its preclinical activities with KPL-404, a monoclonal antibody inhibitor of the CD40 co-stimulatory receptor, in T-cell-dependent, B-cell-mediated disorders. Kiniksa expects to file an IND application with the
FDAin the second half of 2019 and initiate a Phase 1 clinical trial in the first half of 2020.
January 2019, Kiniksa exercised its exclusive option to acquire all of the outstanding capital stock of Primatope Therapeutics, Inc., the company that owns or controls the intellectual property related to KPL-404. Kiniksa expects to close this transaction in March 2019.
- Kiniksa is evaluating the progression of KPL-045, a monoclonal antibody inhibitor of the CD30 ligand co-stimulatory molecule, pending preclinical data from the program in the context of the company’s portfolio. Kiniksa no longer 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 discovered and developed by Regeneron and is approved by the
Mavrilimumab is an investigational fully-human monoclonal antibody that is designed to antagonize 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 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-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.
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.
