Summary

This trial tests JSP191, an antibody that helps clear out diseased blood cells, in adults with MDS or AML who are getting a stem cell transplant. By blocking a critical connection on blood cells, JSP191 makes room for new, healthy stem cells.

Eligible Conditions
  • Myelodysplastic Syndrome
  • Acute Myeloid Leukemia

Timeline

Screening ~ 3 weeks
Treatment ~ Varies
Follow Up ~up to 1 year post donor cell transplant (28 days dose limiting toxicity period)
This trial's timeline: 3 weeks for screening, Varies for treatment, and up to 1 year post donor cell transplant (28 days dose limiting toxicity period) for reporting.

Experimental Treatment
Group I: Blood Stem Cell Transplant w/ anti-CD117 conditioningExperimental Treatment1 Intervention
The phase 1a portion of the study plans to assess approximately 3 planned dose cohorts of JSP191: 0.3 mg/kg, 0.6 mg/kg, and 1.0 mg/kg to determine the maximum tolerated dose for expansion. Subjects will receive a single dose of intravenous JSP191 antibody followed by monitoring for antibody clearance. Once the antibody has cleared below a certain level, patients will receive stem cell transplant and be monitored for hematopoietic recovery. The phase 1b portion of the study will enroll additional subjects at the expansion dose in order to further explore the safety, feasibility, and PK of that dose.
