Testing the Safety of Anti-Cancer Drug, CX-5461 (Pidnarulex), in Treating Lymphoma With Specific Changes in the MYC Gene
United States50 participantsStarted 2026-10-13
Plain-language summary
This phase Ib/II trial tests the safety, side effects, best dose and how well giving CX-5461 works for the treatment of patients with B-cell non-Hodgkin lymphoma. CX-5461 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving CX-5461 may be safe, tolerable and/or effective in treating patients with B-cell non-Hodgkin lymphoma.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Patients must have one of the following subtypes of aggressive B-cell non-Hodgkin lymphomas: double-expressor lymphoma (DEL), high-grade B-cell lymphoma (HGBL) with MYC and BCL2 and/or BCL6 rearrangement, or Burkitt lymphoma (BL). Eligible patients must have received at least two prior lines of treatment for diffuse large B-cell lymphoma (DLBCL) or at least one prior line of therapy for Burkitt Lymphoma and must have disease for which no standard curative or palliative treatment options exist or remain effective (Quin et al., 2016)
* Age ≥ 18 years. Because no dosing or adverse event (AE) data are currently available on the use of CX-5461 (Pidnarulex) in patients \< 18 years of age, children are excluded from this study
* Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2 (Karnofsky ≥ 60%). ECOG 3 is allowed if directly related to lymphoma per treating provider
* Absolute neutrophil count ≥ 1,000/mcL
* Platelets ≥ 50,000/mcL
* Total bilirubin ≤ 1.5 institutional upper limit of normal (ULN)
* Patients with documented Gilbert's syndrome may be included if total bilirubin is ≤ 3 × ULN and direct bilirubin is within normal limits
* Aspartate aminotransferase (AST)(serum glutamic oxaloacetic transaminase \[SGOT\])/ alanine aminotransferase (ALT) (serum glutamic pyruvic transaminase \[SGPT\]) ≤ 3 × institutional upper limit of normal (ULN)
* Glomerular filtration rate (GFR) ≥ 60 mL/min/, calculated by multiplying the estimated (e)GFR (mL/min/…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
