Prospective Study of Rituximab in Chemotherapy-Dependent Human Immunodeficiency Virus–Associated Multicentric Castleman's Disease: ANRS 117 CastlemaB Trial
2007
Purpose Single-agent chemotherapy is usually effective in HIV-associated multicentric Castleman's disease (MCD). However, in most patients, chemotherapy cannot be discontinued. Patients and Methods To evaluate the efficacy of four weekly rituximab infusions (375 mg/m2) after discontinuation of chemotherapy in HIV-associated MCD, 24 patients were enrolled onto a prospective open-label trial. Results At study entry, the median time from MCD diagnosis was 21 months. All patients had stable disease on chemotherapy and were dependent on chemotherapy for a median time of 13 months. The median CD4 cell count was 270 × 106/L, and the plasma HIV RNA was less than 50 copies/mL in 18 patients. One patient died with progressive disease at day 15, and 23 patients completed the four cycles of rituximab. Sustained remission (SR) off treatment at day 60 (primary end point) was achieved in 22 patients (92%). From day 60 to day 365, one patient died with acute respiratory failure of undetermined origin, and four patients e...
