pain 31#57volume 1,123#21

Pain rank 57 of 76, volume rank 21 of 76 by industry trials. Trials here amend about 0.7x and fail enrollment about 1.0x the map median.

What this is worth

The amendment proxy, priced. Order of magnitude, anchor cited, assumptions on the table.

Per 100 industry trials in this cell, about 29 rewrite their eligibility criteria at least once. At the industry average of $450k direct cost per amendment, with the 6+ weeks of delay each not even counted, that is at least $13M at stake per 100 trials. Across the roughly 1,123 industry trials here, the floor is $146M.

If amendments fell by10%$15M30%$44M50%$73M

Assumes $450k direct cost per amendment (industry average; Phase II median runs lower, Phase III higher, and delay cost is excluded), applied to the proxy rate. The proxy counts only trials with at least one eligibility change, so this understates the true exposure. How this is derived.

The signals

Industry sponsors first, since that is the commercial buyer, each figure shown against the map median. All-sponsor figures follow. A trial counts as concluded once it has finished, whether completed, terminated or withdrawn.

Why these trials stoppedsponsor decision leads

The most common category here is sponsor decision (35 of 121 stopped). A keyword pass runs first; free text it could not place was sorted once by a frozen AI classification into these same categories, auditable rather than a live model. "No enrollment recorded (inferred)" is not a stated reason: it is read from a zero enrollment count, meaning the trial never enrolled anyone. "Not reported" means the sponsor left the field blank, shown rather than hidden.
