Brief summary

Current protocols use G-CSF to mobilize hematopoietic progenitor cells from matched sibling and volunteer unrelated donors. Unfortunately, this process requires four to six days of G-CSF injection and can be associated with side effects, most notably bone pain and rarely splenic rupture. BL-8040 is given as a single SC injection, and collection of cells occurs on the same day as BL-8040 administration. This study will evaluate the safety and efficacy of this novel agent for hematopoietic progenitor cell mobilization and allogeneic transplantation based on the following hypotheses: * Healthy HLA-matched donors receiving one injection of BL-8040 will mobilize sufficient CD34+ cells (at least 2.0 x 10\^6 CD34+ cells/kg recipient weight) following no more than two leukapheresis collections to support a hematopoietic cell transplant. * The hematopoietic cells mobilized by SC BL-8040 will be functional and will result in prompt and durable hematopoietic engraftment following transplantation into HLA-identical siblings with advanced hematological malignancies using various non-myeloablative and myeloablative conditioning regimens and regimens for routine GVHD prophylaxis. * If these hypotheses 1 and 2 are confirmed after an interim safety analysis of the data, then the study will continue and include recruitment of haploidentical donors.

Arm 1: Donors
-Donors will receive subcutaneous (SC) BL-8040 in the morning (Day 1) followed by leukapheresis approximately 180 minutes (up to 270 minutes) after the injection per institutional protocol. If the donor does not reach the collection goal for mobilization (≥ 5.0 x 10\^6 CD34+ cells/kg), a second leukapheresis will be performed on Day 2 (24 hours ± 2 hours from the BL-8040 injection) in an effort to reach a total of ≥ 5 x 10\^6 CD34+ cells/kg and at least ≥ 2 x 10\^6 CD34+ cells/kg from the combined collections.

Arm 2: Recipients
-All or part of the leukapheresis product will be infused into the recipient per institutional guidelines. The day of the infusion will be considered Day 0; if the infusion occurs over multiple days, the final day of infusion will be considered Day 0

Time to Neutrophil Engraftment Post-transplant in Patients Undergoing Allogeneic Stem Cell Transplant (Arm 2 Recipients Only)

-Time to neutrophil engraftment is measured by determining the first of 3 consecutive measurements of neutrophil count ≥ 500/μL following conditioning regimen induced nadir.

Time frame: Up to Day 28

Population: -Donors are not evaluable for this outcome measure.

Time to Platelet Engraftment Post-transplant in Patients Undergoing Allogeneic Stem Cell Transplant (Arm 2 Recipients Only)

-Time to platelet engraftment is measured by determining the first of 3 consecutive measurements of platelet count ≥ 20,000/μL without platelet transfusion support for 7 days.

Time frame: Through 90 days

Population: -Donors are not evaluable for this outcome measure. 1 recipient was not evaluable due to no platelet nadir and 1 recipient was not evaluable due to no engraftment.
