Phase 3 Development Timeline
ProKidney's Phase 3 PROACT 1 trial is currently ongoing, building on the positive Phase 2 results. Evercore ISI (搜索) analyst Jonathan Miller noted that while the Phase 2 results were "very intriguing," questions remain about some nuances of the data heading into the Phase 3 trial.
Miller indicated that a readout on Phase 3 data could occur as early as the end of 2026, though it could be 18 months before comprehensive Phase 3 data is released. The analyst believes the Phase 3 trial in chronic kidney disease could be a "major catalyst in the kidney space."

The stock had closed at 61 cents on Monday, marking the 17th straight session with a close below $1, and the 46th sub-$1 close over the past 47 sessions.
Despite the positive Phase 2 results, Evercore's Miller maintained his in-line rating on the stock, citing remaining questions about the data that he "can't reconcile completely" as the company advances toward Phase 3 development.
