Study Summary
This trial is testing whether it is safe to give anti-CD22 CAR T cells to people with hairy cell leukemia (HCL).
Who is the study for?
Adults over 18 with hairy cell leukemia (HCL) who have tried, can't receive, or refused other treatments. They must meet specific health criteria like normal organ function tests and not be pregnant or breastfeeding. Participants need to agree to use contraception and sign a consent form.Check my eligibility
What is being tested?
The trial is testing the safety of anti-CD22 CAR T cells in treating HCL. It involves screening tests, chemotherapy drugs infusion, followed by the experimental CAR T cell infusion, with hospital stay and follow-ups for up to 15 years.See study design
What are the potential side effects?
Potential side effects may include reactions related to immune system activation such as fever and fatigue, complications from low blood counts like infections or bleeding, and possible toxicities affecting organs due to the engineered T cells.

Eligibility Criteria:
This trial includes the following eligibility criteria:- My kidney function is within the normal range.I do not have HIV, HBV, or HCV infections.I am HIV positive.I can do most of my daily activities unless my illness prevents me.I have tested positive for hepatitis B or C, but if I later test negative, I can still participate.My bone scans show worsening bone damage.I have an enlarged spleen causing symptoms.I had a stem cell transplant over 100 days ago, have no active GVHD, and haven't taken immunosuppressants for 30 days.I haven't taken any experimental cancer drugs or antibody therapies in the last 2 weeks.I am older than 18 years.I have low blood counts, a large spleen, growing cancer masses, or quickly increasing cancer cells.I do not have any severe illnesses that my doctor thinks could make participating unsafe for me.I am on steroids without a dose increase for at least 1 week.I have HCL/HCLv and can't use or haven't responded to specific treatments.I am currently taking warfarin.My cancer is confirmed as HCL or HCLv by specific tests.I haven't had CAR therapy in the last 30 days or have no lasting CAR T-cells.I had a stem cell transplant over 100 days ago, have no active GVHD, and haven't taken immunosuppressants for 30 days.I have a brain condition but it meets the study's specific requirements.My diagnosis of hairy cell leukemia is confirmed by specific tests.My disease can be measured or seen through tests.I can care for myself but may not be able to do active work, except if my condition is due to HCL.My organs are functioning well and I've recovered from previous treatment side effects.I had another cancer but was treated successfully over two years ago and am now in remission, except for cervical carcinoma in situ.My cancer cells show high CD22 levels.I haven't had chemotherapy, immunotherapy, or radiation in the last 2 weeks.I have a growing mass or bone lesion larger than 2cm.I finished my radiation therapy at least 3 weeks ago, or it was less intense and I have measurable disease outside the treated area.My kidney function is within the required range.I have a brain condition but may still qualify for the trial.Over 80% of my cancer cells show CD22.My cancer can be measured or seen through tests.My organs are functioning well and I've recovered from previous treatment side effects.I am older than 18 years.

Frequently Asked Questions
These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.
What are the tangible benefits that participating in this clinical trial might offer patients?
"The primary objectives of this long-term study are to assess the safety and feasibility of the treatment over the course of 15 years. Additionally, researchers will monitor for progression-free survival, event-free survival, and overall survival."
Answered by AI
What is the total number of people who have signed up to participate in this research project?
"That is correct. The listing on clinicaltrials.gov indicates that this study, which was first made public on May 23rd, is recruiting patients. The research is only looking for 23 individuals from a single site."
Answered by AI
What are some possible risks associated with CD22 CAR T-cell infusion?
"With CD22 CAR T-cell infusion, we are still in the early stages of research. This being a Phase 1 trial, there is limited data supporting both safety and efficacy, so we gave it a score of 1."
