Fulcrum Therapeutics' recent collaboration with Sanofi for the development and commercialization of losmapimod, its potential blockbuster treatment for facioscapulohumeral muscular dystrophy (FSHD), has been widely lauded as a strategic victory. The deal injects $80 million upfront into Fulcrum's coffers, extends its runway into 2027, and allows the company to focus on preparing for a US launch while leveraging Sanofi's global reach and expertise.

But a closer look at the transcript of Fulcrum's Q1 2024 earnings call reveals a hidden signal, a subtle but potentially significant clue that suggests something far more seismic could be on the horizon: a full-fledged acquisition of Fulcrum by Sanofi.

While the initial focus is on a partnership, the call transcript reveals a curious emphasis on manufacturing and supply. Paul Bruno, Fulcrum's Head of Corporate Strategy and Business Development, stated that while Fulcrum will continue to supply losmapimod globally for both clinical and commercial purposes, there is "flexibility for Sanofi to take over manufacturing and supply in the future." This seemingly innocuous statement takes on a different dimension when viewed in the context of Sanofi's recent M&A activity. The pharmaceutical giant has been aggressively pursuing acquisitions, particularly in the rare disease space. Their $3 billion neuromuscular franchise, featuring drugs like Fabrazyme, Cerezyme, and Myozyme, is a clear indication of their commitment to this area.

Furthermore, Sanofi's acquisition of Principia Biopharma for $3.68 billion in 2020, just a year after Principia completed its Phase 3 trial for a BTK inhibitor, demonstrates their willingness to acquire companies based on promising late-stage assets.

The parallels with Fulcrum are striking. Losmapimod is a first-in-class oral therapy for FSHD, a market estimated at 30,000 patients in the US and a million globally. With Phase 3 data expected in Q4 2024, losmapimod is poised to become the standard of care, potentially generating billions in annual sales.

Sanofi's "flexibility" to take over manufacturing is likely not just a casual consideration. It could be a deliberate strategic move, a stepping stone to a full acquisition. By integrating Fulcrum's manufacturing capabilities, Sanofi could streamline production, control costs, and maximize losmapimod's potential value.

The deal terms themselves also hint at a possible buyout. The $975 million in potential milestone payments, coupled with tiered royalties starting in the low teens, suggest Sanofi is keen to retain a significant stake in losmapimod's success. This level of investment, particularly for a drug not yet approved, would make a full acquisition more financially palatable.

Furthermore, Alex Sapir's statement that Fulcrum is now focused on "ensuring the best possible launch in the US" could be interpreted as laying the groundwork for an acquisition. By proving losmapimod's commercial viability in the lucrative US market, Fulcrum would become an even more attractive target for Sanofi.

While a buyout is not explicitly mentioned, the breadcrumbs are there. Sanofi's aggressive M&A strategy, their commitment to rare diseases, their "flexibility" regarding manufacturing, and the generous deal terms all point to a potential acquisition being a logical next step.

This hypothesis is further supported by Fulcrum's current market cap of around $448 million. With losmapimod's blockbuster potential and a clear path to market, a buyout price in the range of $2-3 billion wouldn't be unreasonable.

The coming months will be crucial. Positive Phase 3 data for losmapimod, coupled with a strong launch plan for the US market, could well trigger a Sanofi buyout offer. Investors should pay close attention to any announcements regarding manufacturing transfer and Sanofi's evolving role in losmapimod's commercialization. The hidden signal in the current quarter transcript might be the prelude to a major shakeup in the rare disease landscape.

As you can see, there's a significant increase in the use of "partnership"-related terms in the Q1 2024 call, following the announcement of the Sanofi deal. While "acquisition" and "buyout" are not explicitly mentioned, the shift in language could reflect a deliberate move towards closer integration with Sanofi, potentially setting the stage for a future acquisition.
