A Phase 1/2 interventional study of UB-VV400 and Rapamycin (sirolimus) in Lymphoma, B Cell, Lymphoma Non-Hodgkin and High Grade B Cell Lymphoma, sponsored by Umoja Biopharma. Recruiting at 2 sites in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-11-10.
Sponsored by Umoja Biopharma · Phase 1/2, Interventional, and Treatment
This study is a Phase 1/2 dose-finding and dose-confirmation study to evaluate the safety and antitumor activity of UB-VV400. The study will enroll patients with relapsed/refractory B-cell malignancies, including large B-cell lymphoma (LBCL).
1,868 studies on the registry are indexed under Lymphoma, Large B-Cell, Diffuse; 355 are open to participants now.
This study's planned enrollment of 274 is above the median of 45 across 1,497 interventional studies indexed under Lymphoma, Large B-Cell, Diffuse.
Browse Lymphoma, Large B-Cell, Diffuse studies →Umoja Biopharma is the lead sponsor of 3 studies on the registry; 3 are open to participants now.
Compared within Lymphoma, Large B-Cell, Diffuse, this study's primary condition as ClinicalTrials.gg classifies it; the registry's first condition term is Lymphoma, B-Cell. The counts are of registry records indexed under each term, refreshed daily. How we classify →
Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
