Summit Therapeutics Inc.
A clinical-stage biopharmaceutical company founded in 2003 in Oxford, England, that develops new medicines for serious diseases — starting with antibiotics and later shifting its focus to cancer treatments such as the lung-cancer drug ivonescimab. It went through a string of odd early names, including CobraDragon and Vastox, before settling on "Summit," a nod to reaching the peak of healthcare. Today it is listed on Nasdaq and runs offices in Miami, California, and the UK.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 3 years: +12.35M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
