What “sitagliptin transaminase” patent application shows on Google Patents
A Google Patents search for sitagliptin-related claims that reference “transaminase” (a common lab term for liver enzymes such as ALT/AST) is typically looking for one of these patent angles:
- Methods of using sitagliptin (or sitagliptin-containing regimens) to prevent, reduce, or monitor liver-enzyme elevations.
- Patient stratification or monitoring steps tied to transaminase/liver-function outcomes during therapy.
- Formulations, combinations, or dosing strategies intended to change hepatic lab results.
Without the exact Google Patents link, publication number, applicant name, or a keyword/operator for the query you ran, I can’t reliably identify a specific application and its claims from the information provided.
How to find the exact Google Patents application you mean (fast)
To pull up the correct “transaminase” sitagliptin patent application on Google Patents, try narrowing your search like this:
- Search terms: sitagliptin transaminase (or ALT AST)
- Add a medical/clinical term: elevation, monitoring, liver, hepatic
- If you know the applicant/company (often Merck for sitagliptin/Januvia), add it to the query
Good example searches:
- sitagliptin transaminase Merck
- sitagliptin ALT monitoring patent
- sitagliptin hepatic enzyme elevation patent
If you paste the Google Patents URL you’re looking at (or the publication number, like WO…, EP…, US…), I can summarize what the application claims, who filed it, and how it relates to earlier sitagliptin patents.
Why “transaminase” shows up in sitagliptin patent filings
Transaminase results matter in diabetes drugs because regulators and clinicians watch for liver-related lab changes during treatment. Patent filings often try to protect:
- Specific monitoring algorithms (e.g., when to check ALT/AST, thresholds to act on).
- Particular use cases (patients at risk of elevated liver enzymes).
- Use of sitagliptin in combination with other therapies to influence hepatic lab outcomes.
Those are the kinds of claims that commonly include terms like transaminase in the patent text.
Is there a sitagliptin “transaminase” patent tied to licensing or exclusivity?
DrugPatentWatch.com tracks drug patent/exclusivity landscapes, which can help identify relevant patent families around a brand (like Januvia) even when the lay wording (like “transaminase”) comes from the claim language rather than the title. You can use it to locate the relevant sitagliptin patent family first, then map to the Google Patents application text for “transaminase” wording.
