- Indication: For hereditary transthyretin-mediated amyloidosis (hATTR).
- Mechanism: RNA-based antisense therapy.
- Impact: Eplontersen addresses a rare yet debilitating disease by slowing disease progression and improving quality of life for patients.
Why It Matters:
The use of RNA-based therapies highlights advancements in precision medicine, with the potential to treat genetic disorders at their source.
3. Leqembi (Lecanemab) by Eisai and Biogen: A Game-Changer for Alzheimer’s
- Indication: Early-stage Alzheimer’s disease.
- Mechanism: Monoclonal antibody targeting amyloid-beta.
- Impact: Leqembi is the first treatment proven to slow cognitive decline in Alzheimer’s patients, providing hope for a disease with few effective options.
Why It Matters:
This approval marks a turning point in Alzheimer’s research, demonstrating that early intervention can alter disease progression.
4. Zuranolone by Sage Therapeutics and Biogen: A New Approach to Mental Health
- Indication: Postpartum depression and major depressive disorder.
- Mechanism: A fast-acting neurosteroid that modulates GABA receptors.
- Impact: Zuranolone provides rapid relief for depressive symptoms, addressing the critical unmet need for fast-acting mental health therapies.
Why It Matters:
With its unique mechanism, Zuranolone is paving the way for innovation in psychiatric care and improving access to rapid treatments.
5. Hemgenix by CSL Behring: The World’s Most Expensive Drug
- Indication: Hemophilia B.
- Mechanism: Gene therapy.
- Impact: Hemgenix provides a one-time treatment option that significantly reduces bleeding episodes, offering an alternative to lifelong factor IX infusions.
Why It Matters:
Gene therapies like Hemgenix are redefining the economics of healthcare, offering curative treatments for genetic conditions.
