PRP vs PRF vs standard care for chronic skin ulcers
This study tests whether a treatment made from your own blood (platelet-rich plasma or platelet-rich fibrin) can help heal chronic skin ulcers better than standard care. If you have a non-healing ulcer that fits the size and duration criteria, and you are generally healthy, you may be able to participate.
CairoAges 18–65 - NCT06209619RecruitingPhase 1
Study of CC-99282 plus rituximab after CAR-T for lymphoma
This trial tests combining an experimental pill (CC-99282) with the immunotherapy drug rituximab for people with B-cell non-Hodgkin's lymphoma whose cancer did not fully respond to CAR-T cell therapy. The goal is to improve results after CAR-T.

Healthy volunteers platelet exosome study
This study looks at tiny particles released by platelets in healthy people. It aims to understand what these particles normally look like.
MilanAges 20–60 - NCT06292715Recruiting
Spleen shrinking procedure for severe hypersplenism
This trial tests a procedure that uses heat or cold to shrink part of the spleen and block some of its blood supply, which may improve low blood counts caused by cirrhosis-related hypersplenism. It is for patients whose low white blood cells or platelets have not improved with medicine.
Tianjin, Tianjin MunicipalityAges 18–65 - NCT06328127Recruiting
Positive psychology program for stem cell transplant survivors
This study tests a positive psychology program—simple exercises to help you feel better emotionally—for people who are about 3 months past a donor stem cell transplant. It's done over the phone, so you can join from home.
Tampa, FloridaAges 18 years+ - NCT06247501RecruitingPhase 2
CAR-T therapy for children with B-cell ALL needing transplant
This study tests a new type of immune-cell therapy (called CAR-T cells) for children and young adults with a specific blood cancer (B-cell ALL) who need a stem cell transplant. The treatment uses a patient's own T-cells that are modified to find and kill cancer cells with the CD19 marker.
SeoulAges Up to 25 years - NCT06021678RecruitingPhase 1/Phase 2
EX103 for relapsed or refractory CD20-positive lymphoma
This trial tests a new drug called EX103 for people whose non-Hodgkin lymphoma (a cancer of the immune system) has come back or not responded to earlier treatments. The goal is to see if EX103 is safe and can shrink tumors.
Zhengzhou, HenanAges 18 years+ - NCT05933967RecruitingPhase 2
Orelabrutinib with R-CHOP for newly diagnosed lymphoma
This Phase 2 trial tests whether adding orelabrutinib to standard chemotherapy (R-CHOP) can improve treatment for people with newly diagnosed double-expressing diffuse large B-cell lymphoma. It’s intended for adults who are well enough to receive treatment and whose lymphoma is in the body (not in the brain/spinal fluid).
Nanchang, JiangxiAges 18–70 - NCT06019364Enrolling by invitation
Whole Blood Transfusion for Acute Bleeding
This trial looks at people who received whole blood transfusions during a sudden, heavy bleeding episode. It aims to learn more about how well whole blood works in these situations.
ÖrebroAges 18 years+ - NCT06061094RecruitingPhase 2
Ph+ ALL chemo with targeted pills and transplant
This study tests a combination of chemotherapy, targeted pills (imatinib or ponatinib), and a targeted immunotherapy (blinatumomab) before a stem cell transplant for adults with a specific type of leukemia called Philadelphia chromosome-positive ALL. The goal is to find the best treatment approach.
AachenAges 18–65 - NCT05949931RecruitingPhase 2
Pianzumab plus AVD for newly diagnosed advanced Hodgkin lymphoma
This trial tests whether adding pianzumab to standard AVD chemotherapy works better for newly diagnosed advanced classic Hodgkin lymphoma. It may help people control the cancer and prevent it from coming back, and it will compare outcomes while tracking side effects.
Guangzhou, GuangdongAges 18 years+ - NCT05959252RecruitingPhase 2
Bivalirudin vs heparin for blood thinning during ECMO
This Phase 2 trial compares two blood-thinning medicines—bivalirudin and heparin—in people on ECMO (a machine that supports breathing and/or circulation). It aims to see which medicine works better and is safer while you are connected to the ECMO circuit.
Sydney, New South WalesAges 18 years+ - NCT05921305RecruitingPhase 3
Low-dose methotrexate plus steroid for early acute GVHD
This Phase 3 trial tests whether a specific low-dose medication (methotrexate) together with standard steroid treatment can improve early outcomes in patients with acute graft-versus-host disease after a stem cell transplant. It may help control the immune reaction that attacks the body after transplant.
