ALLERSPRAY

1st topical filmogen spray for

the treatment and prevention of Allergic Rhinitis (AR)

Physiopathology:

Nearly 15-20% world population suffers from Allergic Rhinitis. Allergy is a false reaction of the immune system to a substance. Allergens stimulate topical TH1 & TH2 cells. Cytokines (proteins) produced by TH2 cells stimulate B cells to proliferate & differentiate into IgE producing cells. IgE binds to mast cells which liberates histamine.

Upon a following exposure, the allergens bind directly to the IgE antibodies on the mast cells which instantly release histamine & other inflammatory cytokines, triggering allergic symptoms, inflammation, edema, & pain. Histamine & IgE production after an allergen attack is nearly instant.

 

Ideal Treatment should:

  1. Act topically to avoid side effects
  2. Stop contact between allergen & mucosa to block the allergic reaction
  3. Remove/neutralize histamine topically on the nasal surface
  4. Minimize inflammation
  5. Act within a few seconds / minutes

Current situation:

An effective treatment must be multitarget. Many OTC & a few Rx drugs such as corticosteroids, antihistamines, decongestants, leukotriene receptor antagonists, mast cell stabilizers, anticholinergic which are mono-target and have multiple side effects.

 

Estimated market for an anti-allergic rhinitis drug:

Current US$ 9 Bn to US$ 14 Bn in 2022.

Allergic rhinitis is a complex immunological disease involving allergens & 3 key proteins: IgE + histamine + Inflammatory proteins. The only way to treat such a disease effectively is to minimize allergen contact, so as to neutralize IgE activity to reduce histamine release, & remove histamine. Unfortunately, multiple target drugs are not yet discovered.

VITROBIO‘s Completely NEW Therapeutic Approach:

1994, when a few scientists established VITROBIO with a 20-year R&D program.  The resulting filmogen solution (patented worldwide) forms a protective barrier on the nasal mucosa, which minimizes and stops the contact between the nasal mucosa & the allergens. This mechanical and topical approach consequently allows to rapidly reduce histamine & IgE on the nasal surface, and thus efficiently and quickly alleviate the allergy symptoms.  (European PAEXA research award & French Academy of Science award).

Product Presentation:

15 ml spray for topical application on the nasal mucosa. VITROBIO  name: ALLERSPRAY. Class I medical device in EU.

Clinical Efficacy:

A double blind, randomized, placebo-controlled study was conducted in continuous allergen exposed AR suffering patients at Nexus Clinical Research. 31 patients were treated with Allerspray v/s 15 with saline solution, 3-4 applications per day for 3 weeks. Results show that Day 1 post dose (scoring made 30min after 1st product administration) effects are very marked. Day 2 mean rTNSS is comparable to Day 1 iTNSS, but all allergic rhinitis relief progresses continuously through week 3, indicating that unlike currently available anti-allergic drugs, Allerspray reduces progressively and effectively the allergen-induced symptomatic manifestations of rhinitis. Even after 3 weeks of treatment, there were no side effects or rebound effects, which is a big plus compared to existing drugs. Stopping allergen – nasal mucosa contact results in reduced histamine & IgE activity without any side-effect.
