Brian DeSchuytner: trading record in brief
Brian DeSchuytner is a declared insider of Mersana Therapeutics, Inc. (finance chief), with filings sourced from SEC (Form 4). The record holds 8 filings, for trades running from 14 January 2022 to 6 January 2026.
The filings describe grants, exercises and other transfers rather than trades on the open market. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.
The newest entry dates from 6 January 2026: a transaction, in Mersana Therapeutics, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 4 days. For comparison, the SEC allows two business days to file a Form 4. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
