Rna Based Therapeutics For Neurodegenerative Diseases is a treatment approach for neurodegenerative diseases. This page provides comprehensive information about its mechanism of action, clinical evidence, and therapeutic potential.
RNA-based therapeutics represent a novel approach to treating neurodegenerative diseases by targeting the genetic basis of these conditions. These therapies include antisense oligonucleotides (ASOs), small interfering RNA (siRNA), microRNA (miRNA) inhibitors, and messenger RNA (mRNA) therapies. Several have received FDA approval, with many more in clinical development.
ASOs are single-stranded DNA sequences that bind to specific messenger RNA (mRNA) targets, either blocking translation or promoting RNA degradation:
ASO → Complementary base pairing with target mRNA
├── RNase H recruitment → mRNA cleavage
└── Steric blocking → Translation inhibition
| Drug | Target | Disease | Approval |
|---|---|---|---|
| Tofersen (Qalsody) | SOD1 | ALS | 2023 |
| Nusinersen (Spinraza) | SMN2 | SMA | 2016/2017 |
| Drug | Target | Disease | Phase |
|---|---|---|---|
| BIIB105 | ATXN2 | ALS/FTD | Phase I |
| WVE-004 | C9orf72 | ALS/FTD | Phase I/II |
| ASO-GRM2 | GRM2 | ALS | Preclinical |
| IONIS-MAPT | MAPT | AD | Phase I/II |
siRNA molecules trigger the RNAi pathway to specifically silence disease-causing genes:
miRNA inhibitors (antagomirs) and miRNA mimics can restore dysregulated gene expression:
| miRNA | Target Disease | Mechanism | Development Stage |
|---|---|---|---|
| miR-124 | AD, PD | Neuronal development | Preclinical |
| miR-29 | AD | APP regulation | Preclinical |
| miR-7 | PD | α-synuclein | Preclinical |
| miR-155 | AD, ALS | Neuroinflammation | Preclinical |
mRNA-based approaches deliver coding sequences to produce therapeutic proteins:
Tofersen (Qalsody): FDA-approved ASO for SOD1-mutant ALS
C9orf72 Targeting:
RNA therapies require efficient delivery across the BBB:
