The odds of success also increased with age, with patients 45 years and older 3.5 to almost 7 times more likely to achieve CROT than younger patients, also a statistically significant finding.
There were four serious adverse events across 155 cycles of the lymphoma regimen, and one with 90 cycles of arthritis dosing, all infectious and none fatal. Ms. Kushner cautioned the true rate was probably higher, since their review data might have missed some cases.
Race, sex, and disease duration had no significant effect on response rates. About 60% of the patients were women.
Rituximab, approved in 1997, is a CD20-directed cytolytic antibody.
There was no industry funding for the work, and Ms. Kushner didn’t have any disclosures.
