Note on Biologic Patents

Matching patents to biologic drugs is far more complicated than for small-molecule drugs.

DrugPatentWatch employs three methods to identify biologic patents:

1. Brand-side disclosures in response to biosimilar applications

These patents were identified from disclosures by the brand-side company, in response to a potential biosimilar seeking to launch. They have a high certainty of blocking biosimilar entry. The expiration dates listed are not estimates — they're expiration dates as indicated by the brand-side company.

2. DrugPatentWatch analysis and company disclosures

These patents were identified from searching various sources, including drug labels and other general disclosures from the brand-side company. This list may exclude some of the patents which block biosimilar launch, and some of these patents listed may not actually block biosimilar launch. The expiration dates listed for these patents are estimates, based on the grant date of the patent.

3. Patents from broad patent text search

For completeness, these patents were identified by searching the patent literature for mentions of the branded or ingredient name of the drug. Some of these patents protect the original drug, whereas others may protect follow-on inventions or even inventions casually mentioning the drug. The expiration dates listed for these patents are estimates, based on the grant date of the patent.

Market Overview of SOMAVERT

Product Profile and Therapeutic Indication

SOMAVERT is indicated for adults with acromegaly who exhibit inadequate response to surgery and/or radiation therapy. Its mechanism involves blocking growth hormone receptors, thus reducing insulin-like growth factor 1 (IGF-1) levels, alleviating disease symptoms. Since its approval, SOMAVERT has maintained a niche positioning, addressing unmet needs in resistant acromegaly cases.

Market Size and Patient Demographics

The global prevalence of acromegaly is estimated at approximately 3-4 cases per million annually, with an estimated 20,000 cases worldwide, predominantly in developed markets (e.g., US, EU). Treatment-resistant cases represent a smaller subset, maintaining a limited but steady demand for biologics like SOMAVERT.

Competitive Landscape

SOMAVERT faces competition primarily from somatostatin analogs (octreotide, lanreotide) and growth hormone receptor antagonists like Norditropin (by Novo Nordisk) and other emerging biosimilars. However, its unique mechanism positions it as a specialized agent for refractory cases, reducing direct competition but emphasizing the importance of clinical decision-making dynamics.
