(Reuters) -GSK will pay about $1 billion for exclusive rights to further develop and commercialize Johnson & Johnson (NYSE:JNJ)'s hepatitis B therapy, the British drugmaker said on Tuesday.

JNJ-3989 was initially developed by Arrowhead Pharmaceuticals (NASDAQ:ARWR) and licensed to Johnson & Johnson-owned Janssen in 2018.

Exclusive rights to the therapy will fuel the expansion of GSK's own hepatitis B treatment, bepirovirsen, which is currently in late-stage development, the company said.
