Resistant TB: Adjustments to BPaL regimen reduce AEs, not efficacy



Findings represent ‘great news’ in addressing concerns

Dr. Nahid further commented that the results are highly encouraging in light of the ongoing concerns about the effects of linezolid in the BPaL regimen.

“This is great news,” he said. “The ZeNix trial addresses a key concern that providers and patients have had regarding the safety and tolerability of taking 6 months of linezolid at 1200 mg/d as part of the BPaL regimen.

“The findings that doses lower and durations shorter than the current 1,200 mg linezolid daily for 6 months will significantly expand the usability of the BPaL regimen worldwide.”

The inclusion of patients with HIV was essential in the trial, he noted.

“There are drug-drug interactions to be considered, among other factors that impact drug exposure,” Dr. Nahid said.

“Inclusion of patients living with HIV in this study means that any modifications to the BPaL regimen considered by the WHO [World Health Organization] and other policy decision makers will include data from this key population,” he said. “Of course, more data are needed on safety, tolerability, and efficacy on BPaL in general, and there are international cohorts and demonstration projects underway that will enhance our understanding of the regimen in HIV and in other special populations.”

The authors, Dr. Streeck, and Dr. Nahid have disclosed no relevant financial relationships.
