DUBLIN – Versant Ventures was one of a handful of investors to profit from Passage Bio Inc.’s recent upsized IPO.

The IPO price valued Versant’s holding at $89 million. As well as participating in the IPO – the actual amount involved has not been disclosed – it invested $35 million across three private rounds, between September 2018 and August 2019, according to SEC filings.
