Eli Lilly’s fight with the FDA to get Retatrutide designated as a biologic could change the game for future obesity treatments. Biologic status would give Retatrutide 12 years of market exclusivity—a significant extension beyond the typical 5 years granted to small-molecule drugs like tirzepatide (Mounjaro & Zepbound).
Patents vs. Exclusivity: What You Need to Know
It’s important to understand the distinction between patent protection and market exclusivity:
Patent protection lasts 20 years from the date of filing and can protect against any competitor trying to copy the drug’s formulation or manufacturing process.
Market exclusivity, granted by the FDA, protects the drug from competition by blocking generic or biosimilar approvals for a specific period of time—5 years from market arrival for small molecules and 12 years for biologics.
Following Tirzepatide’s Example
Stay with me here... When tirzepatide (Mounjaro) was first approved by the FDA in May 2022 for type 2 diabetes, it received the standard 5 years of market exclusivity as a new chemical entity (NCE). This means no competitor can bring a generic to market before May 2027—period.
However, when tirzepatide was later approved for obesity management in late 2023, it opened the door for Eli Lilly to potentially gain an additional 3 years of exclusivity for this new indication. In this case, the exclusivity for the diabetes indication could end in 2027, but for the obesity indication, it could be extended until 2030, assuming Lilly is granted the extra 3 years.
After that point, any competitor would need to challenge and invalidate the patent in court to bring a generic version to market.
Why Biologic Designation for Retatrutide Is a Big Deal
Now, turning back to Retatrutide, if Lilly wins biologic status, the drug will have 12 years of guaranteed exclusivity. This is huge compared to the 5 years of exclusivity for non-biologic drugs. On top of that, new indications, such as treating MASH or cardiovascular disease, could extend this exclusivity further, just like tirzepatide’s recent obesity approval will likely extend its control in that market.
This strategy is critical for Eli Lilly because the market for obesity treatments is growing fast, with the potential to bring in billions of dollars. Extending the period of exclusivity, whether through new FDA-approved indications or through biologic designation, delays competition and maximizes profits for the company.
The Future of Obesity Treatments
As Eli Lilly fights for biologic status for Retatrutide and likely looks to secure multiple indications, they are positioning themselves for long-term dominance in the obesity and diabetes treatment market. The combination of biologic designation and the potential for extended exclusivity through additional indications could give Lilly a strong command of the market until nearly 2040. Good news for Lilly investors, frustrating news for patient accessibility and affordability.
