Safety Assessment of a Multipeptide-gene Vaccine in CML
Bu çalışma, Philadelphia kromozomu pozitif kronik miyeloid lösemi hastalarında, Bcr-abl füzyon proteinini hedefleyen çok peptitli aşının sitokin geni içeren bir yardımcı ajanla birlikte güvenliğini değerlendirmiştir. Çalışmaya en az 12 aydır imatinib kullanan ve ilk tam hematolojik yanıtta olan hastalar alınmıştır. Faz 1 aşamasında yürütülmüş ve tamamlanmıştır.
