ALZT-OP1b

AZTherapies, Inc. · Phase 3 active Small molecule ✓ Verified May 2026

ALZT-OP1b is a Small molecule disease-modifying agent Small molecule drug developed by AZTherapies, Inc.. It is currently in Phase 3 development for Early symptomatic Alzheimer's disease (mild cognitive impairment or mild dementia stage). Also known as: ibuprofen, Ibuprofen.

ALZT-OP1b is a small molecule that modulates tau pathology and neuroinflammation to slow cognitive decline in Alzheimer's disease.

ALZT-OP1b is a treatment being studied in a Phase 1 clinical trial for Alzheimer's Disease. The study is a randomized, open-labeled pharmacokinetic study of ALZT-OP1 in normal healthy volunteers.

Likelihood of approval
55.3% 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).
  • CNS / neurology attrition -3.0pp
    CNS drugs have historically high Phase 3 failure rates (notably in Alzheimer disease + major depression).
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

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

ALZT-OP1b targets multiple pathways implicated in Alzheimer's disease neurodegeneration, including tau protein aggregation and neuroinflammatory processes. By addressing these underlying disease mechanisms rather than amyloid alone, the drug aims to provide disease-modifying benefits in early symptomatic Alzheimer's disease patients.
