Key records

The five facts investors ask about first. Each section states what was searched and when. Items still in human review are not shown.

1. Lawsuits

As reported by the issuer on Form D (Items 12–15), latest filing per offering (one offering = one SEC file number; an amendment updates its offering rather than adding one).

Every row is a Form D or D/A on which the issuer listed this name as a related person. Related-person names are matched on first + last name and the address state on the filing; records that share a name but could not be tied together by a second identifier are listed separately below.

"Similar" = offerings in the same industry claiming the same exemption, filed in the last 5 years: Biotechnology / 506(b) (3,253 filings); ranges are the middle half (25th–75th percentile). Computed by PartnerFacts from SEC EDGAR Form D data as of Oct 23, 2026, 5:45 PM ET. Rows without a range: fewer than 30 comparable filings, or not a Rule 506 offering. No ranking or score.

Other listings under the same name

Separate person records under the same name, not combined with this page. Each line says whether it is listed on an issuer this record is also listed on (a second identifier); where it is not, it could be the same person or a different one.
