— Why Commons exists
The big‑pharma advantage isn't science — it's institutional infrastructure. Access to complete submission histories, to how FDA questions get answered, to what a well‑constructed IND actually looks like. Commons exists to close that gap.

03 — Approved vs. how it got approved
Drugs@FDA shows what got approved.
Commons shows how.
Public archives show endpoints — the approval letter, the label, the redacted summary. They tell you what the answer was. Commons is the process record — every sequence, every amendment, every FDA question and every sponsor response.
It tells you how the answer was reached, what went wrong along the way, and what a well‑constructed regulatory argument looks like under pressure.
04 — What's in the archive
Real, complete INDs.
Every sequence. Every amendment. FDA correspondence and sponsor responses. The full longitudinal record of how a regulatory conversation unfolds — not just what got approved. All PII redacted before donation.
-
Every sequence
From original submission through final amendment.
The eCTD lifecycle, complete. Initial INDs, safety reports, protocol amendments, manufacturing changes — in order, with the sponsor's own metadata.
-
FDA correspondence
Information Requests, clinical hold letters, sponsor responses.
Both sides of the conversation. The questions reviewers asked, the answers the sponsor wrote, and the timing between them.

Built with Renaissance Philanthropy.
Renaissance Philanthropy acquires complete IND portfolios from biotechs that have shut down or shelved programs. These are full records — not redacted summaries, not FOIA fragments. Chrona Bio is the technology partner: we built the archive, the search infrastructure, and the viewer.
This is an institutional partnership, not a vendor relationship. Renaissance Philanthropy stewards the donor pipeline. Chrona Bio makes the records accessible. The public gets the data.
