LAS VEGAS – Current guidelines recommend indefinite continuation of antiviral therapy in chronic hepatitis B patients who are hepatitis B e-antigen (HBeAg)-negative. But emerging data suggest that this may not always be the case.
“It’s very provocative data, though not at the guideline level,” W. Ray Kim, MD, said in a presentation at the inaugural Perspectives in Digestive Diseases meeting held by Global Academy for Medical Education.
“There are patients who really have begged to go off treatment because they are sick of taking the medication for year after year after year,” said Dr. Kim, professor of medicine, gastroenterology and hepatology, Stanford (Calif.) University.
In light of new data, taking them off medication might be “something to consider” in noncirrhotic patients if they are completely suppressed, have normal ALT, and have a low level of quantitative hepatitis B surface antigen (HBsAg), Dr. Kim told attendees.
The most current Association for the Advancement of the Study of Liver Diseases guidelines state that unless there is a competing rationale, antiviral therapy should be continued indefinitely for noncirrhotic adults with HBeAg‐negative immune‐active chronic hepatitis B.
They do also say that treatment discontinuation “may be considered” for individuals with proven loss of HBsAg. “However, there is currently insufficient evidence to definitively guide treatment decisions for such persons,” the guidelines say.
Evidence has emerged since those guideline statements were written. Most recently, German investigators published results of the FINITE study showing some long-term responses after stopping tenofovir disoproxil fumarate (TDF) in noncirrhotic, HBeAg-negative patients.
In that prospective, controlled study, 62% of patients who stopped TDF therapy (n = 13) stayed off therapy to week 144 of treatment follow-up. Four of the patients achieved HBsAg loss, and median HBsAg change was –0.59log10IU/mL vs. 0.21log10IU/mL in patients who stayed on TDF therapy.
Investigators said that result demonstrated the potential of stopping long-term TDF treatment and seeing either HBsAg loss or sustained virologic response.
Before that, a retrospective study from investigators in Taiwan showed that age plus level of HBsAg were associated with HBV relapse after entecavir treatment in HBeAg-negative patients. According to investigators, those results suggested HBsAg levels could be used to guide timing of entecavir cessation.
If antiviral therapy is stopped in an HBeAg-negative patient, that patient should be monitored every 3 month for a year for recurrent viremia, ALT flares, and hepatic decompensation, Dr. Kim said at the meeting.
Even before stopping, “there are a number of factors to consider, including biological relapse, flare, hepatic decompensation,” he said.
On the other hand, there is the burden of continued therapy, financial concerns of continuing treatment due not only to medication costs but also long-term monitoring, as well as patient and provider preference, he noted in his presentation.
