Vector Science and Therapeutics Corp. (formerly OpenSesame Acquisition Corp.): what insiders have been doing
Every trade that managers of Vector Science and Therapeutics Corp. (formerly OpenSesame Acquisition Corp.) disclose to SEDI is tracked on this page. The company sits in the Health Care sector. 9 insiders have disclosed 25 filings since 26 October 2025.
Every open-market trade in the period is a purchase: 1 purchase worth €2,705, from 1 insider, and not a single sale. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Those buying include 1 senior executive. Biggest ticket of the year: €2,705, bought by Dobranowski, Alexander Julian and made public on 13 July 2026 (0.045% of market cap).
The most recent open-market purchase was published on 13 July 2026, 119 days ago. Between a trade and the moment it shows up on SEDI, the median delay is 5 days. The shorter that gap, the sooner other investors can see what insiders have done.
Across the 2,733 companies tracked on its exchange, the median is 14 filings; at 25 filings, this issuer sits above that mark. Looking back to 2026, when coverage begins, insiders filed 1 purchase and no sales.
For comparison within the same sector, see the insider buying recorded at Dynavox Group AB and EssilorLuxottica. Every figure here comes from the filings published by SEDI and describes the past, not future prices; it is not investment advice.
