Nasus Pharma is trading at $3.06 (-8.25%) as the cause of its October 21 after-hours decline remains uncertain.

  • No new company-specific announcement explaining the decline surfaced in the search. The latest identified company news was the September 29 announcement that the first patient entered its Phase 1 NS003 study.
  • Major U.S. indexes rose on October 21, so the available market context does not explain the stock’s move in the same direction.
