Experimental Treatment
Group I: Treatment (CD4+ and CD8+ HA-1 TCR T cells)Experimental Treatment3 Interventions
Patients receive fludarabine for 1-3 doses 3-14 days prior to HA-1 TCR T cell administration. Patients then receive CD4+ and CD8+ HA-1 TCR T cells IV over 1 hour.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What is the maximum participant count for this experiment?

"Affirmative. Clinicaltrials.gov information confirms that the trial, which was first uploaded on February 23rd 2018, is actively recruiting patients at a single site and searching for 24 volunteers overall."

Answered by AI

Is the research endeavor currently admitting new participants?

"According to clinicaltrials.gov, this trial is open for enrollment and has been so since its initial posting on February 23rd 2018 with the most recent update occurring on September 7th 2022."

Answered by AI

What goals is this clinical trial striving to achieve?

"This clinical trial will measure the efficacy of administering minor H antigen (HA-1) T cell receptor (TCR) CD8+ and CD4+ T cells over a given time frame. Secondary objectives include assessing the presence, proportion, and persistence of HA-1 TCRs in bone marrow via tetramer or qPCR testing; measuring how long these receptors stay in peripheral blood; as well as determining what percentage of participants develop symptoms or signs related to graft versus host disease through standard GVHD grading criteria."

Answered by AI

Has the Food and Drug Administration green-lit Fludarabine for public use?

"Fludarabine is still in the early stages of development, so its safety was provisionally given a score of 1. Currently, there is limited data on both efficacy and safety for this medication."

Answered by AI

Are there any other precedents of Fludarabine being used in medical research?

"As of the present, 369 trials are underway investigating Fludarabine. Of these active studies, 22 have progressed to Phase 3. Boston Massachusetts holds the most concentration of such clinical research though there are 3764 sites across America conducting related investigations."
