Sponsor-matched active trials from ClinicalTrials.gov (6 as sponsor, 0 as collaborator); "Sponsor" = company is the lead sponsor, "Collaborator" = company is a collaborator. The BP column flags big-pharma involvement as lead sponsor or collaborator (excluding the company itself). The Mgmt guide column shows what management guided for readout timing when a guided program matches the trial (hover for the quote, click for the source).
