Reviewer's view of the efficacy data
FDA: positive rabbit and NHP placebo-controlled trials plus safety data justify use in inhalation anthrax
“When combined with safety data in healthy animals and human volunteers, as well as with positive results from previously conducted placebo trials with raxibacumab in rabbits and non-human primates, the complementary mechanism of action to the antibiotic appears to justify its use in patients diagnosed with inhalation anthrax disease.”
