HAMILTON, Bermuda, Feb. 26, 2020 (GLOBE NEWSWIRE) -- Kiniksa Pharmaceuticals, Ltd. (KNSA) (“Kiniksa”), a biopharmaceutical company focused on discovering, acquiring, developing and commercializing therapeutic medicines for patients with significant unmet medical need, today reported fourth quarter and full-year 2019 financial results and highlighted recent pipeline activity.
“We have the potential to generate data-driven value from multiple clinical-stage assets in 2020,” said Sanj K. Patel, Chief Executive Officer and Chairman of the Board of Kiniksa. “Near-term, given the anti-pruritic response shown in both cohorts of our KPL-716 Phase 1b study as well as recent external mechanistic validation, we are enabling an interim readout from our KPL-716 Phase 2a trial in prurigo nodularis. Data are expected by the end of April.”
Rilonacept (IL-1α and IL-1β cytokine trap)
Kiniksa is evaluating rilonacept for the potential treatment of recurrent pericarditis, a painful autoinflammatory cardiovascular disease.
Kiniksa expects top-line data from RHAPSODY, a pivotal Phase 3 trial of rilonacept in patients with recurrent pericarditis, in the second half of 2020.
Kiniksa recently announced the U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy designation for rilonacept for the treatment of recurrent pericarditis. Kiniksa’s Breakthrough Therapy application was based on final data from an open-label Phase 2 clinical trial of rilonacept in a range of recurrent pericarditis populations.
Kiniksa continues to prepare for the commercialization of rilonacept in recurrent pericarditis by generating evidence on unmet need and disease burden, building disease awareness with payers, physicians and advocacy groups, and establishing core capabilities such as distribution, patient services and data management.
Mavrilimumab (monoclonal antibody inhibitor targeting GM-CSFRα)
Kiniksa is evaluating mavrilimumab for the potential treatment of giant cell arteritis (GCA), a chronic inflammatory disease of medium-to-large arteries.
Kiniksa expects top-line data from a global Phase 2 proof-of-concept trial of mavrilimumab in patients with GCA in the second half of 2020.
Kiniksa and Kite, a Gilead company, recently announced a clinical collaboration evaluating the investigational combination of axicabtagene ciloleucel and mavrilimumab in relapsed or refractory large B-cell lymphoma. The objective of the trial is to determine the effect of mavrilimumab on the safety of axicabtagene ciloleucel. Preclinical evidence shows the potential for interruption of granulocyte macrophage colony stimulating factor (GM-CSF) signaling to disrupt chimeric antigen receptor T (CAR T) cell-mediated inflammation without disrupting anti-tumor efficacy. The Phase 2 trial is expected to commence in the second half of 2020.
KPL-716 (monoclonal antibody inhibitor of signaling through OSMRβ)
Kiniksa is evaluating KPL-716 for the potential treatment of a variety of pruritic diseases, including prurigo nodularis, a chronic inflammatory skin condition.
Kiniksa expects data from a Phase 2a trial of KPL-716 in patients with prurigo nodularis by the end of April 2020.
Kiniksa expects interim data from cohorts of an exploratory Phase 2 trial of KPL-716 in diseases characterized by chronic pruritus in the first half of 2020.
KPL-404 (monoclonal antibody inhibitor of signaling between CD40 and CD40L)
Kiniksa is enrolling a single-ascending-dose Phase 1 clinical trial of KPL-404 in healthy volunteers. The first-in-human trial will provide safety data and pharmacokinetics as well as receptor occupancy and T-cell Dependent Antibody Response (TDAR). Top-line data are expected in the second half of 2020.
For the fourth quarter of 2019, Kiniksa reported a net loss of $31.8 million, compared to a net loss of $42.6 million for the fourth quarter of 2018.
For the full-year 2019, Kiniksa reported a net loss of $161.9 million, compared to a net loss of $103.2 million for the full-year 2018.
Total operating expenses for the fourth quarter of 2019 totaled $32.6 million, compared to $44.1 million for the fourth quarter of 2018. Non-cash share-based compensation expense totaled $5.0 million for the fourth quarter of 2019, compared to $2.6 million for the fourth quarter of 2018.
Total operating expenses for the full-year 2019 totaled $170.0 million, compared to $108.2 million for the full-year 2018. Non-cash share-based compensation expense totaled $15.1 million for the full-year 2019, compared to $5.7 million for the full-year 2018.
As of December 31, 2019, the company had cash, cash equivalents and short-term investments of $233.4 million and no outstanding debt.
Kiniksa expects that its cash, cash equivalents and short-term investments will fund its operating plan into the second half of 2021.

Kiniksa is a biopharmaceutical company focused on discovering, acquiring, developing and commercializing therapeutic medicines for patients suffering from debilitating diseases with significant unmet medical need. Kiniksa’s clinical-stage product candidates, rilonacept, mavrilimumab, KPL-716 and KPL-404, are based on strong biologic rationale or validated mechanisms, target underserved conditions and offer the potential for differentiation. These pipeline assets are designed to modulate immunological signaling pathways that are implicated across a spectrum of diseases. For more information, please visit www.kiniksa.com.
Rilonacept is a weekly, subcutaneously-injected, recombinant fusion protein that blocks interleukin-1 alpha (IL-1α) and interleukin-1 beta (IL-1β) signaling. Rilonacept was discovered and developed by Regeneron Pharmaceuticals, Inc. (Regeneron) and is approved by the FDA under the brand name ARCALYST® for the treatment of Cryopyrin-Associated Periodic Syndromes (CAPS), which includes Familial Cold Autoinflammatory Syndrome and Muckle-Wells Syndrome. Interleukin-1 (IL-1) blockade may interfere with immune response to infections. Serious, life-threatening infections have been reported in patients taking ARCALYST. ARCALYST should be discontinued if a patient develops a serious infection. Taking ARCALYST with tumor necrosis factor (TNF) inhibitors is not recommended because this may increase the risk of serious infections. Kiniksa exclusively licensed rilonacept from Regeneron for recurrent pericarditis and certain other indications. Rilonacept in recurrent pericarditis is an investigational drug. The FDA has granted Breakthrough Therapy designation to rilonacept for recurrent pericarditis.
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 (GM-CSFRα). Kiniksa’s lead indication for mavrilimumab is GCA, an inflammatory disease of medium-to-large arteries. Additionally, Kiniksa and Kite have a clinical collaboration to evaluate mavrilimumab in combination with Yescarta® (axicabtagene ciloleucel) in patients with relapsed or refractory large B-cell lymphoma.
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 CD40-CD40 ligand (CD40L) interaction, a key T-cell co-stimulatory signal critical for B-cell maturation and immunoglobulin class switching. Kiniksa believes disrupting CD40-CD40L interaction is an attractive approach for blocking T-cell mediated, B-cell driven responses, drivers of multiple autoimmune disease pathologies such as rheumatoid arthritis, Sjogren’s syndrome, Graves’ disease, systemic lupus erythematosus and solid organ transplant.
