Enarodustat vs Vadadustat
Same mechanism, same race: design-graded trial evidence for both assets, with the grading rationale shown. Grades describe the quality of the evidence, never the merits of either security.

The trial was randomized and actively controlled with 172 participants, but it was open-label and used hemoglobin, a laboratory surrogate, as its primary endpoint. Because no primary endpoint results or statistical comparison are available, the study provides limited evidence rather than demonstrating a positive or negative treatment effect.
Caveat: this result is taken from a company announcement or a news report of one, not from the trial registry or a peer-reviewed publication. Treat the figures as the sponsor's own statement, not as independently verified evidence.

NCT02648347 · Phase 3 · completed
Participants were randomized to vadadustat or active treatment with darbepoetin alfa, but the trial was open-label; 879 received vadadustat and 872 received darbepoetin alfa. The hemoglobin primary endpoint met the prespecified non-inferiority criterion, while the primary cardiovascular safety comparison did not, making the findings mixed rather than clearly positive.
