EcoR1 Capital Fund, L.P.

All filings by EcoR1 Capital Fund, L.P. on record concern Lakefront Biotherapeutics. The record holds 16 filings, for trades running from 13 May 2025 to 28 July 2025.

The open-market record is one-sided, with 16 purchases worth €2.9M and not one sale. Unlike grants, an open-market purchase is paid for by the insider, at the market price.

A typical purchase (the median) is worth €139k. Of 16 purchases, 16 formed part of a group of insiders buying within 30 days of each other. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. Ninety days after publication, 16 purchases show a median change of +6.9%, with the price up in 94% of them. This is a record of the past, not a forecast.

Most recently, on 31 July 2025, the filings show an open-market purchase worth €211k in Lakefront Biotherapeutics. The median gap between a trade and its publication by FSMA is 6 days. The regulation allows three business days to notify a trade (MAR article 19). This summary is built from FSMA disclosures alone and does not predict where the share price will go.
