Safety of Transplantation of CRISPR CCR5 Modified CD34+ Cells in HIV-infected Subjects With Hematological Malignances

Summary

The investigators performed this study to evaluate the safety and feasibility of transplantation with CRISPR/Cas9 CCR5 gene modified CD34+ hematopoietic stem/progenitor cells for patients that develop AIDS and hematological malignances. Patients will be treated with antiviral therapy (ART) to achieve undetectable HIV-1 virus in peripheral blood before conditioning. CD34+ cells from donors will be infused into the patients after treatment with CRISPR/Cas9 to ablate CCR5 gene.
