Questions About LEAP THERAPEUTICS, INC.
Each answer is built from the values on the SEC filing and the AltStreet ledger, not from the issuer's marketing.
What is LEAP THERAPEUTICS, INC.?
LEAP THERAPEUTICS, INC. is a Delaware corporation that filed a Form D with the SEC on March 13, 2023 in the Pharmaceuticals industry group. The filing claims Rule 506(b) for an offering of equity.
Is LEAP THERAPEUTICS, INC. legit?
AltStreet does not rate legitimacy; it reports the public record. LEAP THERAPEUTICS, INC. filed a Form D with the SEC on March 13, 2023 claiming Rule 506(b). A Form D is a notice of an exempt offering, not a review or approval of it. The newest notice reports $77,219,193 sold to 121 investors. AltStreet's enforcement record (SEC, FINRA and state actions) shows no action naming the issuer as of today. Before investing, confirm the filing on EDGAR, check the seller's registration on FINRA BrokerCheck, and read the offering documents, which a Form D does not include.
Is LEAP THERAPEUTICS, INC. registered with or approved by the SEC?
No. A Form D is a notice that an issuer is selling securities under an exemption from registration, and the SEC does not review, approve, or pass on the merits of the offering. The filing shows that LEAP THERAPEUTICS, INC. claimed Rule 506(b) and disclosed the items the form requires, such as the amount sold, the minimum investment, related persons, and anyone paid to sell the securities. It does not verify the issuer's claims or its business.
How much has LEAP THERAPEUTICS, INC. raised?

Who can invest in LEAP THERAPEUTICS, INC.?
The offering relies on Rule 506(b), which permits sales to accredited investors and to no more than 35 non-accredited investors who meet a sophistication standard, and prohibits general solicitation. The filing reports no non-accredited investors. The filing lists the minimum investment as $0, meaning no minimum was stated.
What is the minimum investment in LEAP THERAPEUTICS, INC.?
The Form D lists the minimum investment as $0, which means the issuer did not state a minimum on the form. The offering documents, not the Form D, set the actual subscription terms.
Who is selling LEAP THERAPEUTICS, INC. and how are they paid?
The Form D names no recipient of sales compensation, which usually means the issuer or its affiliates are placing the securities directly.

Data Methodology
Capital raise figures, investor counts, and filing dates are sourced directly from SEC EDGAR Form D primary documents via the SEC EDGAR submissions API and full-text search index. EDGAR entity profiles and deal-level data are reviewed by AltStreet analysts with backgrounds in corporate finance and securities law — cross-referenced against offering circulars, audited financial statements, and primary regulatory filings before publication. Platform-provided information, where present, is clearly labeled and does not affect EDGAR data or AltStreet editorial coverage.
