The US based company stated that BJT-778 was well tolerated, with no dose-limiting toxicities.

“We anticipate building on this success as we strive to broaden our portfolio of treatments and cures for viral and liver diseases,” said Blujay Therapeutic’s CEO Dr Keting Chu.

In August, Bluejay raised $41 million in Series B financing led by Arkin Bio Ventures.

The company has a licencing agreement with Novartis for its other CHB preclinical pipeline drug, BJT-628.
