Efficacy refers to how well a drug performs compared to current treatment options. The hosts used Gilead Sciences' hepatitis C medication, Sovaldi, as a prime example. Upon its release in 2014, Sovaldi showcased unprecedented cure rates exceeding 90%, drastically outperforming older treatments that had lower effectiveness rates.
This exemplary efficacy allowed Gilead to capture a substantial market share. However, potential competitors must demonstrate equivalent or superior efficacy to successfully penetrate the market, particularly without a head-to-head trial for comparison.
