Annamycin Shines in Sarcoma Study: Moleculin Biotech (MBRX) Delivers Promising Results (But Hold Your Horses, Folks!)

Welcome back to the ongoing saga of Moleculin Biotech (MBRX), my financially-minded friends! Consider this your definitive guide to their latest 8-K filing, dropped on June 4, 2025 – a real page-turner in the ongoing MBRX chronicle.

This 8-K filing and accompanying press release (Exhibit 99.1, for the paperwork pros) detail the topline results from their Phase 1B/2 clinical trial of Annamycin for soft tissue sarcoma lung metastases (STS lung mets). And let me tell you, there’s some good news… but also some stuff that requires a deeper dive.

A Clinical Benefit Rate of 59.4%? 🎉 No cardiotoxicity? Double 🎉! This is the kind of stuff that makes investors do a little happy dance.

The big win? A Clinical Benefit Rate (CBR) of 59.4%! Almost 60% of patients saw some benefit – 18 with stable disease and one with a partial response, according to the 8-K. Even better? The press release highlights the lack of cardiotoxicity, a common concern with similar treatments. [[GREEN_FLAG]] [[GREEN_FLAG]]

Now for the “hold your horses” part. While overall survival (OS) and progression-free survival (PFS) look promising, especially for patients with fewer prior therapies, the median PFS for all participants was 63 days. [[NEUTRAL]] That’s… something to keep an eye on, folks.

While the 63-day median PFS raises an eyebrow, the overall survival data, particularly for less-treated patients, offers a glimmer of hope.
