Immunotherapeutics Announces promising results in an in-vivo proof-of-concept psoriatic human skin model
JERUSALEM, July 15, 2024 – 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
successful in-vivo preclinical study results of its innovative anti IL-17A/F VHH antibody fragment (‘NanoAb’) as a local,
first of its kind, intralesional biological treatment for the large and underserved population of patients suffering from mild to moderate
plaque psoriasis.
The 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.
The Study
The study was conducted by the team of Prof.
Amos Gilhar, a leading researcher and dermatologist who heads the internationally renowned Skin Research Laboratory at the Technion,
Israel Institute of Technology, Haifa. The study aimed to demonstrate that local, intralesional treatment with Scinai’s NanoAb,
which targets the two isoforms of the cytokine IL-17 (A and F) implicated in plaque psoriasis, has at least a non-inferior anti-inflammatory
effect on the psoriatic lesions compared to corticosteroids and systemic biologics.

For this purpose, human skin was transplanted
onto the back of SCID-Beige mice and psoriasis was induced by injection of activated human peripheral blood mononuclear cells (PBMCs)
from patients diagnosed with psoriasis. This disease-induced skin model reproduces key features of plaque psoriasis tissue morphology
as well as the cytokine profile associated with the inflammatory state of plaque psoriasis lesions. The mice were divided into study groups
with each group treated for two weeks. The therapeutic effect was then evaluated for three additional weeks, post the last treatment.
The trial’s study groups included Scinai’s
anti-IL-17 NanoAbs, two comparator approved drugs (Betamethasone, a topically applied corticosteroid used for the treatment of patients
with mild to moderate psoriasis and Secukinumab, a leading monoclonal anti-IL-17A antibody approved for systemic administration for the
treatment of patients with moderate to severe psoriasis), and an unrelated VHH NanoAb used as negative control. The anti-inflammatory
effect of Scinai’s NanoAbs was evaluated by measuring cytokine levels secreted by the skin tissues, including their direct target
IL-17 A/F cytokines together with other inflammatory markers such as TNFa, Psoriasin, HBD-2, IL-22, CD31, HLA-DR and lymphocytes markers
CD4 and CD8. Additionally, the skin’s structure, integrity, and viability were assessed by a histopathological analysis.
The unique ability of Scinai’s NanoAb to
neutralize both IL-17A and IL-17F isoforms was confirmed, this time in-vivo, by the histopathology analysis, which demonstrated that Scinai’s
NanoAb led to reduced levels of both IL-17 isoforms in the psoriatic skin tissue.
In addition, the statistical analysis of these
markers confirmed that the effect of Scinai’s NanoAb on the tested inflammatory markers was similar to that of the two comparator
drugs, supporting the hypothesis that intralesional injection of a nanoAb blocking the IL-17 cytokine can impact the inflammatory cytokine
cascade, and lead to reduction in psoriatic lesion severity and improvement of the skin’s integrity.
The results confirm and build upon previous
reported results from ex-vivo studies done with human skin specimens (conducted by Genoskin) and in a plaque psoriasis in vitro model
with human skin tissue grown in a dish.
Dr. Tamar Ben-Yedidia, Scinai’s Chief Scientist,
noted, “These positive results are very encouraging and mark a significant step forward in the development of a novel treatment
for the underserved needs of the mild to moderate plaque psoriatic patients. To date, most of the innovation related to treatment of autoimmune
diseases has focused on drugs aimed at the more severe cases of these diseases, leaving milder cases mostly with generic topical drugs
and phototherapy treatments. The mild psoriatic patients account for more than 50% of the plaque psoriatic patients and while undertreated
they are prone to painful skin lesions sometimes in locations that generate a considerable disease burden for them. Scinai’s vision
is to provide a highly efficacious, specific, convenient and safe local biologic treatment of plaque psoriasis lesions.”
“I’d like to thank Prof. Amos Gilhar
and his team for their collaboration and excellence,” 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.
