To calculate phase-specific progression probabilities by genetic evidence, we must assign a latest historical development phase to Pharmaprojects drug-indication pairs that are not in active development using other database fields. Country status gives the latest phase for single-indication and preclinical drugs. Other drug-indication phases are determined through assessing the presence or absence of key events and clinical details matching the trial phase and the disease name. Clinical details were only used when other sources were unavailable because this field may contain information about planned or anticipated trials. Details are provided in S2 Text.
