GERMANY- Boehringer Ingelheim’s spesolimab has been approved by the U.S. Food and Drug Administration as a therapy option for generalized pustular psoriasis (GPP) flares in adults.

Spesolimab, sold under the trade name SPEVIGO® in the United States, is a brand-new, highly-selective antibody that prevents the immune system’s interleukin-36 receptor (IL-36R) from being activated, a signaling pathway that has been linked to the pathogenesis of GPP.

The critical EFFISAYIL® 1 Phase II clinical trial’s findings served as the foundation for the FDA’s approval of spesolimab.

Patients having a GPP flare were given spesolimab or a placebo during the 12-week experiment.

The majority of patients had poor quality of life and a high or very high density of pustules at the beginning of the trial.

Compared to placebo (6%), 54% of individuals receiving spesolimab had no visible pustules after one week.

“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.

For the treatment of GPP flares, spesolimab has received designations as a breakthrough therapy in the United States, China, and Taiwan; priority review in the United States and China.

Generalized Pustular Psoriasis (GPP) is a chronic, rare skin condition that can be fatal if neglected.

It is characterized by sudden flare-ups that cause painful, pus-filled blisters to cover significant portions of the body.

Additional symptoms including a fever, headache, excessive exhaustion, or a burning feeling on the skin could also be present.

GPP and the more typical plaque psoriasis can be mistaken, but they are two different conditions.

“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.

Spesolimab is now being evaluated by a number of additional regulatory bodies in addition to the U.S.

For the treatment of GPP flares, spesolimab has received designations as a breakthrough therapy in the United States, China, and Taiwan; priority review in the United States and China.

It has also received orphan drug designation in the United States, Korea, Switzerland, and Australia; rare disease designation; and fast track in Taiwan.

The marketing authorization application for spesolimab in GPP was approved by the European Medicines Agency in October 2021, and the submission is presently being reviewed.
