Clinical development (~8 years, idealized): first-in-human → approval
Audience lens: showing the concept and the “why”, in plain language. Click any phase or gate to read its student view.
Timeline note: The three trial phases sit on the critical path; Phase 2 is where most programs die on efficacy, and Phase 3 is the largest cash outlay before filing.
Two stacked panels share one 8-year timeline. The top panel is a Gantt of clinical workstreams grouped into lanes; the bottom panel shows candidate attrition by clinical phase, aligned to the same timeline. Phases and gates are interactive — focus one and press Enter to read its details for the selected audience.
Funnel counts are per ~100 programs entering Phase 1, using historical industry-average phase-transition rates — a teaching approximation, not a forecast for any single program.
Timeline caveat: Real clinical timelines commonly run 6–10+ years and vary enormously by indication; the 8-year window is a compressed teaching frame.
A larger trial in patients who really have the disease, to see if the drug works and at what dose.
