U.S. FDA approves first treatment option for generalized pustular psoriasis flares in adults

Ingelheim, Germany ,

  • Spesolimab is a monoclonal antibody that inhibits interleukin-36 (IL-36) signaling and is the first treatment specifically approved for the treatment of generalized pustular psoriasis flares
  • After one week of treatment, more than half of patients treated with SPEVIGO® (spesolimab) intravenous injection showed no visible pustules in the EFFISAYIL® 1 trial
  • The approval of SPEVIGO® in the U.S. reinforces the successful acceleration of our late-stage portfolio to bring innovative medicines to patients faster

Ingelheim, Germany, September 2, 2022 –The U.S. Food and Drug Administration is the first regulatory authority to approve spesolimab as a treatment option for generalized pustular psoriasis (GPP) flares in adults, Boehringer Ingelheim announced today. Spesolimab, marketed in the U.S. as SPEVIGO®, is a novel, selective antibody that blocks the activation of the interleukin-36 receptor (IL-36R), a signaling pathway within the immune system shown to be involved in the pathogenesis of GPP. 

“GPP flares can greatly impact a patient’s life and lead to serious, life-threatening complications,” said Mark Lebwohl, M.D., lead investigator and publication author, and Dean for Clinical Therapeutics, Icahn School of Medicine at Mount Sinai, Kimberly and Eric J. Waldman Department of Dermatology, New York. “The approval of spesolimab is a turning point for dermatologists and clinicians. We now have an FDA-approved treatment that may help make a difference for our patients who, until now, have not had any approved options to help manage GPP flares.”

“This important approval reflects our successful efforts to accelerate our research with the aim to bring innovative treatments faster to the people most in need,” said Carinne Brouillon, Member of the Board of Managing Directors, responsible for Human Pharma, Boehringer Ingelheim. “We recognize how devastating this rare skin disease can be for patients, their families and caregivers. GPP can be life-threatening and until today there have been no specific approved therapies for treating the devastating GPP flares. It makes me proud that with the approval of SPEVIGO® we can now offer the first U.S. approved treatment option for those in need.”

The FDA’s approval of spesolimab is based on results from the pivotal EFFISAYIL® 1 Phase II clinical trial.1 In the 12-week trial, patients experiencing a GPP flare were treated with spesolimab or placebo. Most patients at the outset of the trial had a high, or very high, density of pustules, and impaired quality of life. After one week, 54% of patients treated with spesolimab showed no visible pustules compared to placebo (6%).1

In addition to the U.S. approval, spesolimab is currently under review by several other regulatory authorities. To date, spesolimab has received Breakthrough Therapy Designation in the U.S., China mainland and Taiwan, Priority Review in the U.S. and China mainland, Orphan Drug Designation in the U.S., Korea, Switzerland and Australia, Rare Disease Designation and fast track in Taiwan, for the treatment of GPP flares. The European Medicines Agency validated the marketing authorization application for spesolimab in GPP in October 2021 and the submission is currently under evaluation.

Distinct from plaque psoriasis, GPP is a rare and potentially life-threatening neutrophilic skin disease, characterized by episodes of widespread eruptions of painful, sterile pustules. Given that it is so rare, recognizing the symptoms can be challenging and consequently lead to delays in diagnosis. 

About spesolimab

Spesolimab is a novel, humanized, selective antibody that blocks the activation of the interleukin-36 receptor (IL-36R), a signaling pathway within the immune system shown to be involved in the pathogenesis of several autoinflammatory diseases, including GPP. 1-3
It is the first investigational treatment to specifically target the IL-36 pathway for the treatment of GPP flares that has been evaluated in a statistically powered, randomized, placebo-controlled trial. Spesolimab is also under investigation for the prevention of GPP flares and for the treatment of other neutrophilic skin diseases.4,5

About the EFFISAYIL® 1 clinical trial1

EFFISAYIL® 1 (NCT03782792) was a 12-week Phase II trial investigating patients with a GPP flare (N=53), randomly assigned 2:1 to a single 900 mg intravenous dose of spesolimab or placebo.1

After one week, 54% of patients treated with spesolimab showed no visible pustules, compared to 6% of patients treated with placebo.1

Adverse events were reported in 66% of patients treated with spesolimab and 56% of those receiving placebo after one week. Infections were reported by 17% and 6% of patients in the spesolimab and placebo groups respectively (at week one). Serious adverse events were reported in 6% of patients treated with spesolimab (at week one).1 

About generalized pustular psoriasis (GPP)

GPP is a rare, heterogenous and potentially life-threatening neutrophilic skin disease, which is clinically distinct from plaque psoriasis.2, 6 GPP is caused by neutrophils (a type of white blood cell) accumulating in the skin, resulting in painful, sterile pustules all over the body.2, 6 The clinical course varies, with some patients having a relapsing disease with recurrent flares, and others having a persistent disease with intermittent flares.6 While the severity of GPP flares can vary, if left untreated they can be life-threatening due to complications such as sepsis and multisystem organ failure.2 This chronic, systemic disease has a substantial quality of life impact for patients and increased healthcare burden.7 GPP has a varied prevalence across different geographical regions and more women are affected than men.2, 8-10 There is a high unmet need for treatments that can rapidly resolve the symptoms of GPP flares and prevent their reoccurrence, with an acceptable safety profile. 

GPP flares can lead to hospitalization with serious complications, including heart failure, renal failure and sepsis, and the unpredictability and severity of these flares greatly affect a person’s quality of life.
