Oblimersen in Treating Patients With Relapsed or Refractory Waldenstrom's Macroglobulinemia
National Cancer Institute (NCI) tarafından yürütülen bu Faz 1/2 (Phase 1/2) çalışması, nükseden veya tedaviye dirençli Waldenström makroglobulinemisi (Waldenstrom's macroglobulinemia, WM) olan hastalarda oblimersen sodyumun (G3139, bcl-2 antisens oligodeoksinükleotid, Genasense) yan etkilerini, en uygun dozunu ve ne kadar iyi çalıştığını incelemiştir. Oblimersen gibi biyolojik tedavilerin kanser hücrelerinin büyümesini engelleyebileceği veya yavaşlatabileceği düşünülmüştür. Çalışmaya, kemik iliği biyopsisinde %10'un üzerinde lenfoplazmasitik hücre bulunması ve ölçülebilir hastalık ile tanısı doğrulanmış WM hastaları alınmıştır; çalışma tamamlanmıştır.
