Invivyd, Inc.
A biopharmaceutical company making monoclonal antibody medicines for viral diseases, Invivyd's only commercial product is PEMGARDA (pemivibart), a preventive antibody given to certain immunocompromised adults and teens at risk of COVID-19. It was founded in 2020 as Adagio Therapeutics, a spin-out of the antibody-discovery firm Adimab, and renamed Invivyd in 2022. The name hints at its mission of building antibodies that outpace fast-mutating viruses.

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 all recorded history: +1.63M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
