RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.
About This Trial
Background: B-cell lymphoma is a cancer of white blood cells found in the lymph nodes. It affects the system that fights infections and disease. Researchers want to learn how certain drugs work together to treat B-cell lymphomas. The drugs are venetoclax, ibrutinib, prednisone, obinutuzumab, and lenalidomide (ViPOR). Objective: To study the safety of ViPOR for people with B-cell lymphoma. Eligibility: People ages 18 and older with B-cell lymphoma whose cancer has returned or not improved after treatment Design: Participants will be screened with: * Medical history * Physical exam * Blood, urine, and heart tests * Tissue sample from previous procedure * Imaging scans * Registration for counseling on the risks of lenalidomide. They must get counseling at least every 28 days. Participants will have a bone marrow aspiration before treatment. Participants may have tumor samples taken. Participants will get ViPOR in 21-day cycles. For up to 6 cycles: * Participants will get one drug by IV on days 1 and 2. * Participants will take the other four drugs by mouth on most days. After their first dose of venetoclax, they will stay in the clinic for at least 8 hours and return the next day for monitoring. They may be admitted for more drugs or monitoring. Participants will keep a drug diary. Participants will have a physical exam and blood and urine tests at least once per cycle. They will have scans 4 times over 6 cycles. Participants will have a visit about 1 month after their last dose of study drug. They will then have visits every few months for 3 years, and once a year for years 4 and 5. Visits include a physical exam, blood tests, and scans.
What Stage of Research Is This?
Phase 1 trials test a new treatment for the first time in humans, focusing on safety, dosing, and how the body processes the drug. For Lymphoma, a Phase 1 study typically enrolls a small number of participants — often healthy volunteers or patients who have exhausted standard treatment options. Phase 1 results determine whether a treatment moves into larger Phase 2 efficacy studies.
This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.
Target enrollment of 155 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Lymphoma subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

How to Talk to Your Doctor About This Trial
Bring the printable summary of this trial — including the NCT ID (NCT03223610), the sponsor (National Cancer Institute (NCI)), and the key eligibility criteria — to your next appointment. Your doctor can review the inclusion and exclusion criteria against your medical history, lab values, and current treatments to assess whether you are likely to qualify. They can also help you weigh whether trial participation makes sense alongside your existing care plan.
Useful questions to walk through together: What does the trial protocol require beyond standard care? How long is the active treatment phase, and how long is follow-up? Are there study visits at sites I can reach? Who pays for the trial-specific procedures, and who pays for standard-of-care portions?

Who can participate in NCT03223610?
Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.
How do I contact the trial site for NCT03223610?
Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.
Is participating in a clinical trial safe?
Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
