This is a Phase 1/1b, open-label, first in human study of CPI-818, an oral interleukin-2-inducible tyrosine kinase (ITK) inhibitor for the treatment of relapsed/refractory (R/R) T-cell lymphoma.. This trial will study the safety, tolerability, and anti-tumor activity of CPI-818 as a single drug.

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.
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.
The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).
Your pathology report is the document that shows this.
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 weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
CYP3A is a group of enzymes, mainly CYP3A4, in the liver and gut that break down many medicines. Some medicines, supplements and foods (grapefruit, St John’s wort) slow them down or speed them up, which changes how much of a study drug stays in the body.
Studies list them so they can be avoided or switched; bring a list of everything you take, including supplements.

Started May 2019 (actual). Primary completion is estimated for Dec 2026, 91 months after the start.
Of 59 phase 1 interventional studies under Lymphoma, T-Cell, half reached primary completion within 57 months of starting (the median), counting those still running; a quarter within 26 and three quarters within 99. This study's planned 91 months is above that.
Since we started tracking on Sep 25, 2026, the dates moved once, on Oct 22, 2026: primary completion Apr 2026 → Dec 2026 and completion Apr 2026 → Dec 2026.
