Brain cancer hope: new drug cocktail targets rare lymphoma
NCT ID NCT04446962
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding lenalidomide or ibrutinib to standard chemotherapy (R-MPV) can improve outcomes for adults aged 18-65 with newly diagnosed primary central nervous system lymphoma. The trial has two parts: first, finding the safest dose, then randomly assigning patients to one of the two drug combinations. The goal is to see if more patients achieve complete remission after four cycles of treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- lenalidomide (Revlimid) and ibrutinib (Imbruvica)
- What this could lead to
- If successful, this could improve the chance of complete remission for people with a rare brain lymphoma, potentially leading to a more effective first treatment.
- What could go wrong
- This is an early-phase trial (phase 1b/2) with a small number of participants, so results may not apply broadly. The drugs can cause serious side effects like infections or blood clots.

Inclusion Criteria: 1. Newly diagnosed Primary Central Nervous System Lymphoma (PCNSL). 2. a) Aged between 18 and 60 (\>18 and \< 60) - phase IB b) Aged between 18 and 65 (≥ 18 and ≤ 65) - phase II. 3. Histological confirmed diagnosis of Primary central nervous system lymphoma of Diffuse Large B-Cell Lymphomas (DLBCL) type OR patients with a measurable typical cerebral lesion on MRI with a diagnosis made by cytology and/or by flow cytometry on the vitreous or on the cerebral spinal fluid. 4. Measurable lesion on MRI with gadolinium enhancement. 5. Adequate hematological, renal and hepatic function (Laboratory Parameters realized within 14 days before inclusion): 1. Absolute neutrophil count (ANC) \>1000/mm3 2. Platelets \> 100,000/mm3 independent of transfusion support 3. Alanine aminotransferase and aspartate aminotransferase ≤ 3 x Upper Limit of Normal (ULN) 4. Total bilirubin ≤ 1.5 x ULN unless bilirubin rise is due to Gilbert's syndrome or of non-hepatic origin 5. Estimated Glomerular Filtration Rate ≥ 60 mL/min/1.73m2. 6. Able to swallow capsules. 7. Karnofsky performance status: 40-100% for the phase IB and no restriction on the KPS for the phase II. 8. Able to understand teratogenic risks of the Lenalidomide and Ibrutinib. Patient must be able to understand and fulfill the Lenalidomide Pregnancy Prevention Plan requirements. This plan may be accepted by the person of confidence in case of impaired cognitive status of the patient. 9. Women of childbearing potential (WCBP)\* and men who are sexually active must be practicing a highly effective method\*\* of birth control. Women should avoid a pregnancy while taking treatment by Lenalidomide or Ibrutinib and for up to 1 month after ending treatment. Men must agree to not to father a child or donate sperm during treatment by Lenalidomide or Ibrutinib and up to 3 months after the last dose of study drug. 10. Women of childbearing potential (WCBP)\* must have a negative serum (beta-human chorionic gonadotropin \[B-hCG\]) or urine pregnancy test at inclusion. 11. Signed informed consent, which could be signed by a person on confidence in case the neurologic status of the patient does not allow him to understand and/or to sign. Exclusion Criteria: 1. Histology other than DLBCL. 2. Positive HIV serology. 3. Active viral infection with Hepatitis B or C virus. 4. Preexisting immunodeficiency and/or organ transplant recipient. 5. Isolated Central Nervous System (CNS) relapse of systemic Non-Hodgkin's Lymphoma. 6. Prior treatment for PCNSL (except corticosteroids). 7. Isolated primary vitreo-retinal lymphoma. 8. Major surgery, within 4 weeks prior to the first dose of study drug. Stereotactic biopsy and vitrectomy are not considered major surgery. 9. History of stroke or intracranial hemorrhage (except minor post biopsy hemorrhage) within 6 months prior to inclusion. 10. Requires anticoagulation with warfarin or equivalent vitamin K antagonists. 11. Requires treatment with strong CYP3A4 inhibitors. 12. Pregnancy or lactation. 13. Clinically significant cardiovascular disease. 14. Any other active malignancy, except basocellular carcinoma and non-invasive cervix cancer. 15. Inclusion in another experimental anti-cancer drug therapy. 16. No social security affiliation. 17. Persons under legal protection.
