Welcome back to the ongoing saga of Rocket Pharmaceuticals, Inc. (RCKT), where we decode the cryptic messages hidden within their SEC filings. Consider this your definitive guide to the latest chapter – and it’s a doozy.

Rocket Pharmaceuticals filed an 8-K on May 27, 2025, and let’s just say it wasn’t filled with good news. The initial filing (8-K) itself was brief, mentioning a clinical hold on their Phase 2 trial of RP-A501 for Danon disease. [[RED_FLAG]] Not ideal, but sometimes these things happen, right? Hold your horses, because the accompanying press release (EXHIBIT 99.1) paints a much grimmer picture.

A patient in the RP-A501 trial died following a serious adverse event related to capillary leak syndrome. Yeah, you read that right. [[RED_FLAG]]

The company is now investigating the cause, with a newly introduced immune suppression agent under scrutiny.

This tragic event raises serious questions about the safety and future of RP-A501.
