Resolves as YES if the Phase 3 trials of Olpasiran demonstrate:
Efficacy:
- The trials must show a statistically significant reduction in lipoprotein(a) [Lp(a)] levels in participants compared to baseline, achieving at least a 50% reduction in median Lp(a) levels. 
- A high percentage of participants achieving Lp(a) levels below 125 nmol/L and 75 nmol/L. 
- Consistent reduction of Lp(a) levels maintained over the trial period. 
Safety:
- The trials must confirm that Olpasiran is safe for participants, with no significant adverse events that would outweigh the benefits. 
- Minimal and manageable side effects. 
- Few serious adverse events linked to the drug's administration. 
Regulatory Progress:
- The trial results must be sufficient to warrant progression towards regulatory approval, as determined by the relevant regulatory bodies or the sponsoring company (Amgen). 
Background: Olpasiran is a small interfering RNA (siRNA) therapeutic designed to reduce the production of apolipoprotein(a) in the liver by targeting the mRNA that encodes apolipoprotein(a). Elevated Lp(a) levels are a known risk factor for atherosclerotic cardiovascular disease (ASCVD), and effective reduction of these levels could significantly impact patient outcomes.
The ongoing Phase 3 trial, which began in January 2023, aims to confirm the promising results observed in earlier phases. This trial is crucial for determining the long-term efficacy and safety profile of Olpasiran, with results expected to be published around 2025.
