Medical Research Analyst

The positive regulatory feedback from the Paul Erlich Institute (PEI) is a significant milestone for Scinai Immunotherapeutics. The affirmation to proceed with Phase 1/2a trials for SCN-1, targeting plaque psoriasis, is notable. Plaque psoriasis is a condition with substantial unmet medical needs, affecting millions globally. The PEI's acceptance to use pigs for toxicology studies, bypass clinic trials in healthy volunteers and directly compare SCN-1 to placebo within the same patients are regulatory accommodations that may expedite the development pipeline.

This regulatory green light not only saves time and cost but also reinforces the potential efficacy of SCN-1. For investors, this progression indicates the company's solid groundwork and increasing viability of its product in addressing a prevalent dermatological condition. Moreover, the PEI's comments on manufacturing capabilities boost confidence in Scinai's operational competencies.

Market Research Analyst

The feedback from the PEI is a promising development for Scinai, signaling a positive future for their anti-IL-17 nanoAb. The global market for plaque psoriasis treatments is substantial, with an estimated 13 million patients in key markets. Current treatments for mild to moderate plaque psoriasis often result in low patient adherence due to frequent application needs and side effects. Scinai's product, designed for local and less frequent administration, could capture significant market share if it proves effective and safe in trials.

The anticipated cost savings in the development process, due to regulatory leniencies, position Scinai to potentially allocate resources more efficiently and bring the product to market faster. For retail investors, these developments suggest a potentially lucrative investment opportunity as the company moves closer to clinical validation and market entry.

Financial Analyst

From a financial perspective, the regulatory feedback from the PEI significantly de-risks Scinai's development plan for SCN-1. The cost and time efficiencies gained through strategic decisions, such as the use of pigs for toxicology studies and skipping healthy volunteer trials, are critical. These measures could reduce the overall financial burden and accelerate the path to market, directly impacting the company’s bottom line and future revenue potential.

The acknowledgment of the manufacturing process and the streamlined trial approach are positive indicators. Investors should note that the faster timeline to Phase 1/2a trials reduces the time to potential revenue generation. Additionally, the regulatory feedback provides a solid foundation for Scinai's credibility, which could positively influence stock performance and valuation.

• Clarified preclinical toxicology and clinical program for Plaque Psoriasis First-in-human with intralesional injections for the treatment of patients with mild to moderate Plaque Psoriasis
• The PEI had requested to see data of efficacy in blocking IL-17F; this data became available as per the Company's announcement last week describing the positive in vivo proof of concept results.
• The PEI accepted the Company's position that toxicology studies can be conducted in pigs rather than in Non-Human Primates.
• The PEI accepted the Company's position to compare the SCN-1 to placebo directly in patients with mild to moderate plaque psoriasis while skipping the need for testing in healthy volunteers, resulting in a phase 1/2a clinical trial, which will assess both safety and efficacy in the same trial.
• The PEI agreed to compare SCN-1 to placebo on the same human subject, a strategy that could significantly reduce the number of patients required for the clinical trial
• The PEI commented that the manufacturing process looks well developed and that controls and specifications presented are acceptable
• The Phase 1/2a study is expected to include approximately 24 plaque psoriasis patients and is expected to commence in the second half of 2025 with readout in 2026.

JERUSALEM, July 23, 2024 /PRNewswire/ -- Scinai Immunotherapeutics Ltd. (NASDAQ: SCNI) (the "Company"), a biotechnology company focused on developing inflammation and immunology (I&I) biological products and on providing CDMO services through its Scinai Bioservices business unit, today announced the receipt of minutes of meeting from a recent Scientific Advice ("SA") with the Paul Erlich Institute, Federal Institute for Vaccines and Biomedicines (the "PEI"), which is considered acceptable guidance for IMPD filing with the European Medicines Agency (EMA) and is also considered the European comparable to a pre-IND meeting with the FDA in the U.S. The Company believes that the minutes of meeting reflect positive regulatory feedback, which can be translated into significant time and cost savings in its IL-17 nanoAb drug development plans.

On June 4, 2024, Scinai's scientific team met, over a video conference, with representatives of the PEI for a pre-scheduled, official, Scientific Advisory meeting during which Scinai presented its drug development plan of its novel anti-IL-17A/F nanoAb for the treatment of mild to moderate plaque psoriasis and asked the PEI for guidance and advice on various aspects.

The Meeting

In the meeting, Scinai presented its Chemistry Manufacturing and Controls package, its results from non-clinical ex-vivo and in-vivo studies and its plans for toxicology and first-in-human clinical trial. In addition, Scinai presented the advantages in developing an anti-IL-17 nanoAb for local administration into the psoriatic lesions and the unmet medical need for the intended indication of patients with mild to moderate psoriasis. Scinai indicated that localized treatments to date, including corticosteroid-based creams/ointments and phototherapy require far more intense treatment regimens. These treatments require either more frequent applications (corticosteroids twice a day and biologics once a month) or more frequent visits to the clinic (phototherapy). It is expected that the biological activity of Scinai's nanoAb will last well after the treatment which would potentially result in a far less demanding treatment regimen. Moreover, as a considerable proportion of patients with mild-moderate psoriasis do not respond well to treatments that are intended for mild to moderate psoriasis (corticosteroids, phototherapy) and are treated with biological (mAbs), the unmet need appears well established.

Taken together, it was agreed by the PEI that the results of the non-clinical Proof of Concept (PoC) study (results which were announced on July 15^th, 2024) and clinical explorations will shed further light on the suitability of intended localized treatment setting and regimen for Scinai's nanoAb.

Overall, the PEI commented that the manufacturing process looks well developed, that the in-process controls and the Drug Substance (DS) and Drug Product (DP) specifications are all acceptable. The PEI accepted the Company's approach that for local treatment, conducting toxicology studies in pigs rather than in Non-Human Primates is acceptable. This would translate to a significant time and cost saving for the Company. Additionally, the PEI was in agreement with the proposed design for the clinical trial and its definition as phase 1/2a trial, as it will evaluate both safety and efficacy. They supported the recruitment of mild to moderate plaque psoriasis patients (skipping the evaluation of the NanoAb in healthy volunteers) and comparing the NanoAb to placebo. Again, this will speed up the recruitment stage and lessen the cost. For correct intra-patient comparison, the PEI recommended ensuring a similar lesion size in the experimental and control groups.

Upon receiving the above guidance from the PEI, the Company expects to commence preparations for a pre-clinical toxicology study before commencing a first-in-human clinical trial of its anti-IL 17 NanoAbs for the treatment of plaque psoriasis in 2025.

The unmet market need

Today, there are about 13 million patients diagnosed with plaque psoriasis in the 7 major markets (US, EU5 and Japan). 50% of all psoriasis patients suffer from mild disease and about 28% suffer from moderate psoriasis¹. Patients diagnosed with mild to moderate plaque psoriasis often suffer from considerable and visible lesions which may be uncomfortable, painful, and have a negative impact on their social and mental well-being, especially when the lesions are located on the face, genitals, scalp, palms of hands, and bottom of feet. The therapeutics for mild to moderate plaque psoriasis include mostly corticosteroids, applied topically, and phototherapy. These treatments require very frequent use, have risks for local adverse effects such as skin atrophy and development of tolerance, and suffer from low patient adherence to treatment schedule. The current therapeutics for moderate to severe disease include mostly biologics and JAK inhibitors. While highly efficacious, these treatments are administered systemically, are highly expensive and require chronic use, which carries long term health risks and considerable economic burden to the patients and the health care system. Therefore, treatment of mild to moderate plaque psoriasis is suboptimal and can be improved.

Scinai's product candidate is designed to address the major shortcomings of currently available treatments. It is a biologic, intended to be delivered locally, intradermally, into the psoriatic lesions using a very short and almost painless needle. Scinai's product is designed to allow patients with mild to moderate psoriasis to benefit from a low frequency treatment that comes with the high specificity and potency saved for biologics but with significantly reduced risk of local side effects associated with corticosteroids or systemic side effects associated with systemic administration of biologics.

Dr. Tamar Ben-Yedidia, Scinai's Chief Scientist, noted, "It is encouraging to receive such a supportive regulatory summary for our plans. The PEI agreed with the unmet need of the patients with mild-to-moderate psoriasis for a better therapy and accepted our pre-clinical and clinical plans that will allow faster development of this product."

"I'd like to thank the PEI for their collaboration and guidance," continued Ben-Yedidia.

Scinai next intends to further fine tune dosing and drug half-life and conduct a longer duration follow on in-vivo animal study in late 2024, again, in collaboration with Prof. Gilhar of the Technion Israel Institute of Technology, complemented by a pre-clinical toxicology study before commencing a first-in-human clinical trial in late 2025.
