Executive Summary
NRF2-targeted therapies represent a compelling opportunity in neurodegeneration drug development, with approximately 40-50 active trials examining NRF2-activating compounds. The field has seen significant pharmaceutical investment following successful clinical trials in chronic kidney disease (bardoxolone methyl) and COPD. Key investment themes include:
- Direct NRF2 activators (bardoxolone methyl, sulforaphane derivatives)
- Indirect NRF2 modulators (KEAP1 inhibitors, PKC activators)
- Natural product derivatives (isothiocyanates, polyphenols)
- Gene therapy approaches targeting NRF2 pathway components
The biological rationale is strong, but clinical translation has been challenging due to limited CNS penetration and optimal dosing. Companies advancing NRF2 modulators with improved brain delivery represent potential high-value opportunities. [@nrfa]

Activate NRF2 through upstream signaling pathways:
| Target | Compound Class | Examples |
|--------|---------------|----------|
| PKC | Phorbol esters, bryostatin | Limited due to toxicity |
| MAPK | MEK inhibitors | Selumetinib in trials |
| PI3K/Akt | [mTOR](/mechanisms/mtor-signaling-pathway-pathway) inhibitors | Rapamycin, everolimus |
| AMPK | Biguanides, AICAR | Metformin trials in PD |
