Last November, the SEC launched an investigation into Cassava's simufilam research. Scientists — who also held short positions in SAVA stock — claimed Cassava manipulated images used in testing of the experimental Alzheimer's treatment.
On Thursday, Seeking Alpha published a document showing the SEC reached a "five-page case-closing recommendation." The document carries Monday's date.
The agency declined to release the full decision, citing attorney privilege. Representatives of Cassava didn't immediately return a request for comment.
The data manipulation claims have weighed on SAVA stock since last year. The scientists at the center of the allegations also asked the Food and Drug Administration to suspend Cassava's studies. But the agency declined to do so.
According to Cassava, simufilam works by stabilizing an abnormal protein in the brain.
