• Status: Unknown status
• Trial end date: 2015-12-01
• Target enrollment: 0
• Participant gender: All

Summary

A six courses regimen consisting of a 8 hour infusion (ch14.18/CHOmAb 20 mg/m²) for five consecutive days will be administered every 4 weeks, starting 60-180 days after previous haploidentical stem cell transplantation.

Interleukin 2 will be added to cycles 4-6 at days 6,8,10 (1 x 106 IU/m²/d s.c.) Participants will be premedicated with an intravenous antihistamine and ranitidine within approximately 30 minutes prior and during the infusion of the study agent Pain as an anticipated side effect is managed by a standard pain prophylaxis with Morphium hydrochloride Disease status will be evaluated after 3 and 6 courses and after 1 year
