Scinai Immunotherapeutics and Pincell to Host Webinar on a Blockbuster Drug Candidate for Devastating Rare Skin Diseases

The webinar will explore PC111, a novel monoclonal antibody drug candidate with the potential to transform the treatment landscape for Pemphigus Vulgaris and Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis (SJS/TEN).

JERUSALEM, Israel, May 1, 2025 /PRNewswire/ -- Scinai Immunotherapeutics Ltd. (NASDAQ: SCNI), a biopharmaceutical company specializing in inflammation and immunology (I&I) biological products and which provides CDMO services through its Scinai Bioservices unit, today announced that it will be hosting a webinar on Wednesday May 7^th at, at 11:30 AM EST / 18:30 Israel time. The webinar will address the unmet needs in treating Pemphigus Vulgaris and Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis (SJS/TEN) and explore Pincell's PC111, a novel monoclonal antibody targeting soluble Fas ligand (sFasL) as a promising solution.

The webinar will be broadcast via LinkedIn and YouTube. Interested participants can register using the following LINK.

On March 27 , 2025, Scinai announced that it had entered into a binding option agreement for the acquisition of the Italian biotech company Pincell srl. The parties have prepared a grant application, submitted on March 28^th by the wholly owned Polish subsidiary of Scinai, seeking Euro 12 million of non-dilutive capital to fund the next stage of development of PC111. To facilitate the submission of the application, Pincell exclusively licensed PC111 to the subsidiary. The grant application is under the European Funds for a Modern Economy (FENG) program in Poland. An award decision is expected in Q3, 2025. Additional topics will include an introduction to Pemphigus Vulgaris and Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis (SJS/TEN) diseases, the current standard of care, and a review of the drug development plan for PC111 towards marketing authorization. The virtual panel discussion will feature:

• Mr. Amir Reichman – CEO, Scinai Immunotherapeutics
• Prof. Carlo Pincelli, MD – Co-founder & CMO, Pincell
• Dr. Antonino Amato, MD – Chairman & CEO, Pincell
• Dr. Jonathan Sadeh, MD – Scinai Advisory Board; CMO, Bausch Health R&D
• Prof. Michael Schön, MD – Scinai Advisory Board; Dept. Head, Dermatology UMG

Participants will also have the opportunity to submit questions and receive answers during a Q&A session at the end of the webinar.

About PC111

PC111, a fully human, monoclonal antibody that binds to the human soluble Fas ligand (FasL) and thus blocks its activation of apoptosis of skin cells (keratinocytes). This pathway has a major role in several skin blistering disorders, characterized by a very high unmet medical need with significant market sizes. Importantly, PC111 does not suppress the immune system, at variance with many other biologicals treating inflammatory conditions that can lead to significant, at times fatal side effects.

Pincell has successfully developed a proprietary FasL humanized mouse model, with which it studied the involvement of the Fas/FasL pathway in these diseases, and that can be successfully used in other dermatological and non-dermatological diseases, where this pathway may play a key role in disease development and progression.

Pincell has carried out a large number of in-vitro, ex-vivo and in-vivo experiments using PC111 without steroids in validated models of pemphigus, to prove that soluble FasL is a critical target in this disease. Most importantly, Pincell has demonstrated that PC111 can block blister formation without steroids in a transgenic humanized FasL mouse model of pemphigus, indicating that the antibody can work also in a humanized setting and thus suggesting that it may be a novel targeted therapy for this disease at the clinical level. As there is abundant and convincing data supporting the critical role of soluble FasL also in the pathogenesis of SJS/TEN, PC111 could inhibit the mechanisms underlying the progression of this disease, as shown by the in vivo model where it ameliorates ocular conjunctivitis and edema, two main early features of this disease in humans, as well as its progression towards more severe forms.

About Pemphigus, Stevens-Johnson Syndrome, and Toxic Epidermal Necrolysis

Pemphigus, Stevens-Johnson Syndrome (SJS), and Toxic Epidermal Necrolysis (TEN) are severe dermatological conditions that significantly impact the skin and mucous membranes. Pemphigus is an autoimmune disorder characterized by painful blisters and sores, often requiring long-term immunosuppressive medications for disease management, which are associated with a 5-10% mortality. Stevens-Johnson Syndrome is a rare but serious reaction to medications or infections, with a mortality rate of around 5-10%. Toxic Epidermal Necrolysis, the most severe form of SJS, involves extensive skin peeling and blistering over more than 30% of the body surface, with mortality rates ranging from 30-40%. These conditions highlight a significant unmet medical need for more effective treatments and better management strategies to improve patient outcomes and reduce mortality rates.

About Pincell srl

PinCell is a biotechnology company targeting a novel pathological pathway to develop first-in-class anti-inflammatory therapies for the treatment of rare, severe and highly undertreated skin diseases. Based in Milan, Italy, PinCell was founded in October 2008 as an academic spin-off of the University of Modena and Reggio Emilia by the world class dermatology experts Prof. Carlo Pincelli and Prof. Alessandra Marconi. It has previously received seed funding from Sofinnova Partners to develop proof-of-concept data for its lead candidate PC111.
