Measure how often drugs for a disease actually advance from one clinical phase to the next — the registry-derived analog of a probability-of-technical-success (PTRS) benchmark. Groups industry-sponsored interventional trials for the condition by normalized intervention (drug) name, then reports observed Phase 1→Phase 2 and Phase 2→Phase 3 transition rates as numerator/denominator with an explicit censoring rule, alongside the published BIO/Informa/QLS 2011-2020 benchmark for the matching therapeutic area. Answers "what fraction of Phase 2 assets in NSCLC reach Phase 3", "how does attrition in Alzheimer compare to lung cancer", "what is the probability of success for this indication". Returns the top interventions with their per-phase trial path so the rate is auditable. Counts trial EXISTENCE in the registry, not efficacy readouts or approvals, so it is an upper bound on technical success.
