Wo2015134998a1 human plasma kallikrein inhibitors berotralstat patent?

WO2015/134998 A1 is a World Intellectual Property Organization (WIPO) patent application published as “Human plasma kallikrein inhibitors.” It covers inhibitors of human plasma kallikrein, described in broad terms (typical for a drug-target patent), and may include specific compounds or families of compounds as examples.

Whether berotralstat (BCX-4161) is explicitly disclosed in this particular publication cannot be confirmed from memory alone. To know for sure, you should check the actual patent document text (claims, description, and examples). It may disclose berotralstat by name, by chemical structure, or it may cover broader classes that include berotralstat or its scaffolds.

How to verify quickly:
- Sources: Google Patents (https://patents.google.com) or WIPO PATENTSCOPE (https://patentscope.wipo.int).
- Look up: WO2015134998 A1.
- In the document, use the browser’s search/find function to look for terms like “berotralstat,” “BCX-4161,” “kallikrein,” and any chemical structure examples.
- Check both the “Summary of the invention/Description” and the “Examples” and “Claims” sections to see if berotralstat is expressly disclosed or if the compound falls within a claimed class.

If you’d like, paste the abstract, claim language, or a screenshot of the relevant pages here, and I can help interpret whether berotralstat is disclosed or encompassed by the claims. If you need a legal assessment or freedom-to-operate check, consider consulting a patent attorney.
