The short version

Patrick Trojer is listed as an executive officer and director on 4 SEC Form D filings by 2 issuers between Oct 2019 and Dec 2025: Triana Biomedicines, Inc. (Lexington, MA — pharmaceuticals — 2022–2025; $120.1M reported sold to 20 investors) and CONSTELLATION PHARMACEUTICALS INC (Cambridge, MA — biotechnology — 2019; $99M reported sold to 30 investors).

What this means 2 separate companies raised money with this person listed as executive officer and director, over about 6 years. Across those companies the filings report $219.1M sold in total.

Listed alongside David Grayzel (3 shared filings), Jigar Raythatha (3 shared filings), Joshua Resnick (3 shared filings), Shelley Chu (3 shared filings), Milind Deshpande (2 shared filings) and 15 others.

What this means These are the other officers, directors or promoters the companies named on the same forms — the team around Patrick. Each name links to their own page.

1 of the issuers belongs to the sponsor group Third Rock (7 issuers, $2.62B reported sold, 2010–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Third Rock has 7 companies on file and $2.62B reported sold in total — the group page shows the whole track record in one place.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA) — none found.

What this means Nothing turned up where we looked (3 sources). That does not prove there is nothing — it means none was found in those sources on that date.

We compared 4 public filings for Patrick Trojer and found 3 differences: Offering amount changed between filings; No amendment in the last 12 months on an offering that may still be open; and more below.

What this means These are differences between the sponsor's own SEC filings — both values, dates and sources are listed in Key records, section 4. Most have ordinary explanations; ask the sponsor.

4. Differences between public sources

Comparisons cover issuers and sponsor groups — see the issuer pages under Deals

3 differences found between the filings for Patrick Trojer (compared 4 filings on Oct 24, 2026)

Note · Feb 11, 2022 – Apr 19, 2022

Offering amount changed between filings — Triana Biomedicines, Inc.

The Feb 11, 2022 filing says $80,000,016 offered; the Apr 19, 2022 Form D/A says $85,100,014.

What this means The target raise changed. Raising the cap is common when a deal grows; ask whether the extra money has the same terms and use.

Sources
Note · Jan 28, 2022 – Apr 19, 2022

No amendment in the last 12 months on an offering that may still be open — Triana Biomedicines, Inc. (latest filing Apr 19, 2022)

The latest filing for this offering is dated Apr 19, 2022 (first sale Jan 28, 2022). It reports $42,550,007 sold of $85,100,014 offered. No later amendment is in our index as of Oct 24, 2026.

What this means SEC rules expect a yearly amendment while an offering is still going. The raise may simply have ended — a Form D does not say when it closed. Ask the sponsor whether the offering closed, when, and at what amount.

Sources
Note · Apr 19, 2022 – Dec 4, 2025

Address moved from Waltham, MA to Lexington, MA — Triana Biomedicines, Inc.

The people listed on the Apr 19, 2022 filing give Waltham, MA; on the Dec 4, 2025 filing they give Lexington, MA.

What this means Businesses move; this just shows the two places and dates. If you were told one city and the forms say another, ask which is current.

Sources
What is compared

What is compared: every Form D and D/A we hold for this subject, side by side — filing dates vs. first-sale dates (the 15-day rule), amendment timing on open offerings (the yearly-amendment expectation), amounts sold, investor counts, offering amounts and minimums across amendments, industry and size bands, addresses, how each person's name and role is written, paid sellers' CRD numbers, and (for groups) where the member companies were formed and sit. Everything is as filed by the issuer; the SEC does not check it. Differences are common and usually have ordinary explanations — we show both values, the dates, and the source so you can ask. As of Oct 24, 2026.

5. Money to insiders

None reported on 3 offerings — no sales commissions, finder's fees or proceeds to insiders

Same business address

10 other issuers file from the same address

A shared address can mean the same team, a shared office building or a registered agent. It is a lead, not a conclusion.

Registrations and other filings

Adviser registration (Form ADV)

None of the 2 issuers this person is listed on appears in Form ADV (searched 24,962 advisers as of Oct 2, 2026). A person is never an adviser firm; Form ADV is checked for the issuers and the management companies they are listed with.
