Nasdaq-listed shares of Immuron rallied 8% on Thursday morning following the news. The CEO stated that while Travelan is imported into the U.S. from Australia, it is not a pharmaceutical product but a dietary supplement, and is therefore not expected to be impacted by U.S. pharmaceutical tariffs.

Immuron has three therapeutic products under development, including IMM-124E, also known as Travelan, for traveler’s diarrhea. The company stated that it continues to expect trial results for this candidate in October 2025.
