Abstract: Therapies compared in clinical studies can he assessed through the determination of a hazard ratio for long term response between a first a first therapy and a second therapy. Previously, the hazard ratio was determined after a long-term clinical study is conducted to determine the proportion of patients exhibiting a long-term response, such as event free survival or overall survival. Such long-term studies are often cumbersome and expensive. It is has been found that the hazard ratio for long-term response between a first therapy and a second therapy can be determined based on the proportion of patients in a first population of patients receiving the first therapy that exhibit a pathological complete response, the proportion of patients in a second population of patients receiving the second therapy that exhibit the pathological complete response, a patient level effect, and a residual trial level effect.
