About this study

Official title: Phase II Trial Evaluating Safety and Efficacy of Loncastuximab Tesirine as a Maintenance Therapy Following Autologous Stem Cell Transplantation in High Risk Diffuse Large B-cell Lymphoma

Study of loncastuximab tesirine administered intravenously (IV) for maintenance therapy following autologous stem cell transplant in patients with relapsed diffuse large B cell lymphoma

Read the detailed description

This is a Phase II, multicenter, open label study of loncastuximab tesirine for maintenance therapy following autologous stem cell transplant (autoSCT) in patients with relapsed diffuse large B cell lymphoma (DLBCL). Patients with relapsed DLBCL confirmed through core biopsy and meeting eligibility criteria will be enrolled in the study. Patients can be enrolled up to 4 weeks prior to autoSCT. Patients will start loncastuximab tesirine between day 30 and 60 after autoSCT as determined by the treating physician. Since majority of the relapses occur early after autoSCT, offering maintenance therapy for a finite duration might be of therapeutic benefit without posing excessive toxicity. Loncastuximab tesirine will be administered intravenously (IV) at every 3 weeks (Q3W) for a total of 6 months (8 cycles).

Loncastuximab tesirineExperimentalPatients will start loncastuximab tesirine for maintenance therapy between day 30 and 60 following autoSCT and will receive a total of 6 months of therapy (8 cycles). Patients will receive IV infusion of loncastuximab tesirine 150 μg/kg at Q3W for the first 2 cycles followed by 75 μg/kg at Q3W for the remaining 6 cycles.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Efficacy Outcome Measure

    Progression-free survival (PFS) assessments will be determined according to Lugano Response Criteria. The distributions of time to event data will be graphically summarized using Kaplan-Meier (KM) curves and their median and confidence intervals will be estimated using KM estimates.

    Measured: From the start date of treatment initation until the date of progression or death from any cause, whichever occurs first, assessed up to 1-year following autoSCT

  2. Safety Outcome Measure

    Evaluate the safety and tolerability as defined by CTCAE 5.0 criteria

    Measured: Up to 30 days after last dose of study treatment

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing loncastuximab tesirine in people with Relapsed Diffuse Large B-cell Lymphoma, run by Barbara Ann Karmanos Cancer Institute at 1 site in United States.

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 20 inclusion and 26 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: withdrawn, as of the sponsor's last update on 1 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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 was withdrawn before enrolling participants, so there are no results.

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?

Efficacy Outcome Measure (time frame: From the start date of treatment initation until the date of progression or death from any cause, whichever occurs first, assessed up to 1-year following autoSCT). The study lists 2 primary outcomes in all. 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 1 Nov 2023.
