About this study
Official title: A Phase 2, Multicenter, Open Label Dose-ranging Study of Sepantronium Bromide in Patients With Relapsed/Refractory c-Myc Rearranged High-grade B-cell Lymphoma (HGBCL)
This is a multi-center Phase 2 study to determine the safety and efficacy of sepantronium bromide (SepB) in adult patients with relapsed or refractory high-grade B-cell lymphoma
Read the detailed description
This is a multi-center, open label, dose-ranging Phase 2 study evaluating the safety and efficacy of SepB in patients with relapsed/refractory c-Myc rearranged HGBCL.
Cohorts of three patients will be enrolled at each dose level for SepB with expansion to six patients, if necessary, to assess toxicity.
Following the completion of 2 cycles of treatment of each cohort, an independent Data Monitoring Committee (DMC) will review the safety data to assess study drug related toxicities from the current cohort. Following this review, a decision will be made to continue dose escalation to the next dose level, to declare that a given dose level is the level of dose-limiting toxicity (DLT) or to further explore toxicity at the dose level in question by enrolling additional subjects to a maximum of six subjects at that level.
An additional 6 patients will be enrolled at the recommended Phase 2 dose (RP2D). The RP2D will be established on the basis of the maximally tolerated dose between the two specified dose levels as well as other relevant data, including clinical signals of activity, pharmacokinetic (PK) and pharmacodynamic (PD) data.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Sepantronium Bromide in people with High-grade B-cell Lymphoma and Burkitt Lymphoma, run by Cothera Bioscience, Inc at 11 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 4 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 11 sites in China, South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Safety and tolerability and recommended Phase 2 dose of sepantronium bromide (time frame: From time of signing informed consent through 30 days after the last dose of study drug, an average of 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Nov 2026; AzTrials last refreshed its copy on 8 Nov 2026.
