The aging global population further contributes to higher demand for diagnostic imaging procedures.
Gadoteridol, marketed under brand names such as ProHance, competes with other gadolinium-based contrast agents like gadobutrol (Gadavist, Gadovist), gadopentetate dimeglumine (Magnevist), and gadodiamide (Omniscan). Its market share is influenced by factors such as efficacy, safety profile, cost-effectiveness, and physician preference.
What is the Intellectual Property Landscape for Gadoteridol?
The original patent protection for gadoteridol has largely expired in major markets. The foundational patents covering the composition of matter and its use have lapsed, opening the door for generic manufacturers.
Key patents for gadoteridol (comprising gadolinium and the ligand DTPA-BMA) were filed in the late 1980s and early 1990s. For example, the U.S. patent for gadoteridol was granted in the early 1990s, with an expiration in the mid-2000s, factoring in patent term extensions.
This patent expiry has led to the introduction of generic versions of gadoteridol in various regions. Generic competition typically results in price erosion and increased market accessibility.
However, pharmaceutical companies often employ strategies to extend market exclusivity. These can include:
