New drug combo aims to tackle tough lymphoma
NCT ID NCT05222555
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a modified intravenous dosing schedule of tafasitamab combined with oral lenalidomide in 53 adults with relapsed or refractory diffuse large B-cell lymphoma who are not eligible for a stem cell transplant. The main goal is to evaluate safety and how the drug moves through the body, with a secondary focus on tumor response. It is an early-phase, open-label trial.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tafasitamab (a targeted antibody) and lenalidomide (an immune-modulating drug)
- What this could lead to
- If successful, this could offer a new treatment option for people with relapsed or refractory diffuse large B-cell lymphoma who cannot have a stem cell transplant.
- What could go wrong
- This is an early-phase trial with only 53 participants, so results may not apply broadly. Side effects from the drug combination could be significant, and the modified dosing may not improve outcomes.
This is an AI summary of the original study and may miss details. Read our disclaimer.

Major Inclusion Criteria: 1. Capable of giving signed informed consent 2. Age 18 years or older 3. Histologically confirmed diagnosis of DLBCL 4. Tumor tissue for retrospective central pathology review must be provided as an adjunct to participation in this study. 5. Patients must have: * relapsed and/or refractory disease * at least one bidimensionally measurable, PET positive disease site (transverse diameter of ≥1.5 cm and perpendicular diameter of ≥1.0 cm at baseline) * received at least one, but no more than three previous systemic regimens for the treatment of DLBCL and one therapy line must have included a CD20-targeted therapy * Eastern Cooperative Oncology Group 0 to 2 6. Patients not considered in the opinion of the investigator eligible to undergo intensive salvage therapy including ASCT 7. Patients must meet the following laboratory criteria at screening: * absolute neutrophil count ≥1.5 × 10\^9/L * platelet count ≥90 × 10\^9/L * total serum bilirubin ≤2.5 × ULN or ≤5 × ULN in cases of Glibert's Syndrome or liver involvement by lymphoma * alanine transaminase, aspartate aminotransferase and alkaline phosphatase ≤3 × ULN or \<5 × ULN in cases of liver involvement * serum creatinine clearance ≥ 60 mL/minute 8. Patients who received previous CD19 targeted therapy (other than tafasitamab) must have CD19 positive lymphoma confirmed on a biopsy taken since completing the prior CD19 targeted therapy 9. Patients with primary refractory disease who received at least one, but no more than three previous systemic regimens (including a CD20 targeted therapy) Major Exclusion Criteria: 1. Patients who are legally institutionalized or concurrent enrollment in another interventional clinical study 2. Patients who have: * other histological type of lymphoma * a history of "double/triple hit" genetics 3. Patients who have, within 14 days prior to Day 1 dosing: * not discontinued CD20-targeted therapy, chemotherapy, radiotherapy, investigational anticancer therapy or other lymphoma specific therapy * undergone major surgery (with 4 weeks) or suffered from significant traumatic injury * received live vaccines (within 4 weeks). * required parenteral antimicrobial therapy for active, intercurrent infections 4. Patients who: * have not recovered sufficiently from the adverse toxic effects of prior therapies * were previously treated with IMiDs® (e.g. thalidomide, LEN) * have history of hyper sensitivity to compounds of similar biological or chemical composition to tafasitamab IMiDs® and/or the excipients contained in the study treatment formulations * have undergone ASCT within the period ≤ 3 months prior to signing the informed consent form. * have undergone previous allogenic stem cell transplantation * have a history of deep venous thrombosis/embolism and who are not willing/able to take venous thromboembolic event prophylaxis during the entire treatment period * concurrently use other anticancer or experimental treatments 5. History of other malignancy that could affect compliance with the protocol or interpretation of results. Exceptions * Patients with any malignancy appropriately treated with curative intent and the malignancy has been in remission without treatment for \>2 years prior to enrollment are eligible * Patients with low-grade, early-stage prostate cancer (Gleason score 6 or below, Stage 1 or 2) with no requirement for therapy at any time prior to study are eligible 6. Patients with: * positive hepatitis B and/or C serology. * known seropositivity for or history of active viral infection with human immunodeficiency virus (HIV) * CNS lymphoma involvement * history or evidence of clinically significant cardiovascular, CNS and/or other systemic disease that would in the investigator's opinion preclude participation in the study or compromise the patient's ability to give informed consent * history or evidence of rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption * gastrointestinal (GI) abnormalities (issue with absorption) including the inability to take oral medication * history or evidence of severe hepatic impairment (total serum bilirubin \> 3mg/dL), jaundice unless secondary to Gilbert's syndrome or documented liver involvement by lymphoma * history of hypersensitivity to any of the study treatments or its excipients or to drugs of similar chemical class * any other medical condition which, in the investigator's opinion, makes the patient unsuitable for the study 7. Female participants: Agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods and refrain from breast feeding and donating eggs; agreement to ongoing pregnancy testing during the course of the study, and after study therapy has ended Male participants: agreement to remain abstinent (refrain from heterosexual intercourse) or use a condom and agreement to refrain from donating sperm
