Bernd R. Seizinger (board member) discloses dealings in 3 companies, chiefly Aprea Therapeutics, Inc., Aptose Biosciences Inc. and Oncolytics Biotech Inc. Between 30 June 2021 and 30 June 2026, the trades on record add up to 14 filings.
Every open-market trade on record is a purchase: 7 purchases worth €299k, and no sale. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Other entries cover 6 share grants. 2026 to date brings 2 purchases and no sales.
A typical purchase (the median) is worth €42k. On 4 out of 7 purchases, another insider of the same company was buying within the same 30 days. Purchases made close together by different insiders form what is called a cluster.
