Brief summary

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

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.

Design outcomes

Primary

MeasureTime frameDescription
Safety and tolerability and recommended Phase 2 dose of sepantronium bromideFrom time of signing informed consent through 30 days after the last dose of study drug, an average of 6 monthsFrequency, severity and relatedness of adverse events and the frequency of adverse events requiring discontinuation of study drug or dose reductions

Secondary

MeasureTime frameDescription
Complete response rateFrom first dose of study drug through the last dose of study drug, an average of 6 monthsPercentage of patients who experience a confirmed Complete Response at any time during the treatment phase
Duration of responseFrom first dose of study drug through to time of progression, an average of 6 monthsTime from the first documentation of a Complete Response or a Partial Response until the time to objective tumor progression
Overall response rateFrom first dose through the last dose of study drug, an average of 6 monthsThe ORR is defined as the percentage of participants who achieve either a Partial Response or Complete Response at any time during the treatment phase
Overall survivalFrom first dose of study drug through date of death, irrespective of cause, an average of 6 monthsThe time from the first dose of study drug until death from any cause or date of last follow-up for living and lost to follow-up patients
Progression Free SurvivalFrom first dose of study drug through relapse, disease progression or death due to any cause, an average of 12 monthsThe time from first dose until relapse, disease progression or death due to any cause
Clinical benefit rateFrom first dose of study drug through the last dose of study drug, an average of 6 monthsProportion of patients who achieve a Complete Response, Partial Response or Stable Disease during the treatment phase
