Abstract

fetched live from OpenAlex

Objective To examine the potential therapeutic value of new medicines approved in the US and both approved and not approved in Australia. Methods A list of new medicines approved by the US Food and Drug Administration (FDA) between 1 January 2015 and 31 December 2020 was assembled and it was determined which of these medicines were also approved in Australia. Three metrics - first in class, priority review and therapeutic rating by two independent organisations - were used to determine the potential therapeutic value of the medicines. The percent of medicines with and without potential significant therapeutic value was compared using each of the three metrics. Results A total of 273 drugs were approved by the FDA, of which 147 (53.8%) were approved by the Therapeutic Goods Administration, the Australian regulator. For each of these three metrics, the percent of medicines with and without potential significant therapeutic value approved in Australia was the same: first in class (yes vs no: Chi-squared P = 0.8562), priority review (yes vs no: Chi-squared P = 0.4593), therapeutic rating (major/moderate vs little/no: Chi-squared P = 0.9006). Some of the 126 drugs not approved may be therapeutically important. Conclusions New medicines approved in the US between 2015 and 2020 without potential significant therapeutic value are as likely to be introduced into Australia as drugs with potential significant therapeutic value. Some potentially valuable drugs may not have been submitted for approval in Australia by the companies making them.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
