HAMILTON, BERMUDA**– August 3, 2021** – 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 second quarter 2021 financial results and recent corporate and portfolio activity.

“Our commercial team is doing a superb job with the launch of ARCALYST in recurrent pericarditis,” said Sanj K. Patel, Chief Executive Officer and Chairman of the Board of Kiniksa. “Feedback received from physicians and patients highlights the transformational potential of ARCALYST for patients suffering from recurrent pericarditis. We have seen strong uptake and look forward to using this momentum to accelerate broader adoption across this underserved population.”

“We are executing on the development of our clinical-stage pipeline,” said John F. Paolini, MD, PhD, Chief Medical Officer of Kiniksa. “The potential broad utility of mavrilimumab across multiple indications is increasingly promising, and we expect data from our Phase 3 clinical trial in COVID-19-related ARDS in the first quarter of 2022. We are enrolling a Phase 2b clinical trial of vixarelimab in prurigo nodularis and believe vixarelimab has the potential to make a meaningful impact on these patients’ lives by addressing both the pruritus and the skin nodules associated with this devastating disease. KPL-404, our anti-CD40 program, has potential across a range of autoimmune diseases, and we plan to initiate a Phase 2 proof-of-concept clinical trial in rheumatoid arthritis in the fourth quarter of this year.”

Portfolio Activity

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

· ARCALYST<br> net revenue in the second quarter of 2021 was $7.7 million.
- The<br> second quarter of 2021 represented Kiniksa’s first quarter of ARCALYST sales. ARCALYST<br> became commercially available through Kiniksa on April 1^st^, 2021.
--- ---
- Greater<br> than 100 physicians who did not participate in Phase 3 RHAPSODY prescribed ARCALYST to at<br> least one recurrent pericarditis patient.
--- ---
- Greater<br> than 65% of all recurrent pericarditis enrollments came from physicians practicing outside<br> of the 12 Phase 3 RHAPSODY clinical trial sites in the U.S.

--- ---
- Kiniksa<br> OneConnect^TM^ provided access, initiation<br> and ongoing support for existing ARCALYST cryopyrin-associated periodic syndromes (CAPS)<br> and deficiency of IL-1 receptor antagonist (DIRA) patients transitioning to Kiniksa product<br> as well as new ARCALYST patients for all approved indications.
--- ---

Mavrilimumab (monoclonal antibody inhibitor targeting GM-CSFRα)

· Kiniksa’s<br> interactions with the U.S. Food and Drug Administration (FDA) resulted in defined paths for<br> Phase 3 development of mavrilimumab in COVID-19-related acute respiratory distress syndrome<br> (ARDS) and in giant cell arteritis (GCA).
· Kiniksa<br> today announced additional data from the Phase 2 portion of the Phase 2/3 clinical trial<br> of mavrilimumab in patients with severe COVID-19-related ARDS.

--- ---
· Kiniksa<br> continues to enroll non-mechanically ventilated patients in the Phase 3 clinical trial of<br> mavrilimumab in COVID-19-related ARDS.
--- ---
- Kiniksa<br> discontinued enrolling mechanically-ventilated patients in the Phase 3 trial.
--- ---

- Rheumatoid<br> arthritis was selected for demonstration of KPL-404 proof of concept as it is a well-characterized<br> autoimmune disease with decades of published clinical data across diverse mechanistic classes,<br> allowing for objective evaluation in established endpoints.
--- ---
- The<br> pharmacokinetic lead-in of the planned trial supports characterization of chronic administration<br> of KPL-404 in a patient population and provides optionality to evaluate the therapeutic potential<br> of KPL-404 across a range of other autoimmune diseases with pathologies believed to be mediated<br> by the CD40-CD154 pathway.

--- ---
· ARCALYST<br> can cause serious side effects:
--- ---
· Medicines<br> that affect the immune system may increase the risk of getting cancer.
--- ---

--- ---
· Your<br> doctor will do blood tests to check for changes in your blood cholesterol and triglycerides.
--- ---

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 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.

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 for multiple autoimmune disease pathologies. Kiniksa owns or controls the intellectual property related to KPL-404.
