Allergen Immunotherapy Extract

Johns Hopkins University · Phase 3 active Small molecule

Allergen Immunotherapy Extract is a Allergen immunotherapy Small molecule drug developed by Johns Hopkins University. It is currently in Phase 3 development for Allergic rhinitis, Allergic asthma, Atopic dermatitis. Also known as: ORALTEK®.

Allergen immunotherapy extract desensitizes the immune system to specific allergens by gradually exposing patients to increasing doses, promoting immune tolerance and reducing allergic responses.

Likelihood of approval
59.3% vs 58.3% industry baseline
If approved by FDA: likely 2028–2030
Steps remaining: NDA/BLA submission
Confidence: High
Why this estimate
  • Baseline phase 3 → approval rate +58.3pp
    Industry-wide phase 3 drugs reach approval ~58.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
  • Immunology slight uplift +1.0pp
    Mature endpoint landscape (ACR, DAS28, PASI) makes immunology approvals slightly more predictable.
Predicted approval windows by jurisdiction (conditional on FDA approval)
Regulator Country Likely year Lag vs FDA
FDA US 2028–2030
EMA EU 2029–2031 +0.7 yr
MHRA GB 2029–2031 +0.7 yr
Health Canada CA 2029–2032 +0.9 yr
TGA AU 2029–2032 +1.2 yr
PMDA JP 2029–2032 +1.5 yr
NMPA CN 2030–2033 +2.3 yr

CDSCO IN 2029–2033 +1.8 yr
ANVISA BR 2030–2033 +2.3 yr

Hover any row for the lag rationale. Lag estimates are reduced when the drug has FDA Breakthrough or EMA PRIME designation (sponsors file globally in parallel).

Estimate based on the BIO/Informa industry phase transition rates plus per-drug modifiers for therapeutic area, sponsor type, FDA designations, mechanism, and trial design. Per-jurisdiction lags from Tufts CSDD international approval studies. Not investment, clinical or regulatory advice. Methodology: /methodology#likelihood.

Mechanism of action

The extract contains standardized allergen proteins that are administered in gradually increasing doses to shift the immune response from IgE-mediated (allergic) to IgG-mediated (tolerant) pathways. This process induces regulatory T cells and reduces mast cell and basophil reactivity to the allergen, thereby decreasing symptoms upon natural allergen exposure.
