New drug combo aims to boost stem cell harvest in myeloma patients

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Has received a live vaccine within 30 days of the planned start of G-CSF administration. Seasonal flu vaccines that do not contain live virus are permitted. 11. Known active central nervous system (CNS) metastases or carcinomatous meningitis. 12. A history of allergic reactions attributed to compounds of similar chemical or biologic composition to BL-8040, G-CSF, or other agents used in the study. 13. Has an active infection requiring systemic therapy or uncontrolled infection. 14. Has a known additional malignancy that is progressing or requires active treatment. 15. Has an underlying medical condition that would preclude study participation. 16. Is currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks of the first dose of treatment. 17. O2 saturation \< 92% (on room air). 18. Personal history or family history of Long QT Syndrome or Torsade de Pointes. 19. History of unexplained syncope, syncope from an uncorrected cardiac etiology, or family history of sudden cardiac death. 20.
