What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Loncastuximab TesirineDrug

    Also called Zynlonta, ADCT-402

    Intravenous (IV) Infusion

Study groups in NCT05660395
Study groupRoleWhat they receive
Arm A: Normal Hepatic FunctionExperimentalParticipants will receive loncastuximab tesirine 0.15 mg/kg once every 3 weeks (Q3W) for two cycles, then 0.075 mg/kg Q3W for subsequent cycles (1 cycle = 21 days). Participants who have a toxicity meeting the criteria for dose reduction will have subsequent doses reduced by 50%. If the toxicity recurs, subsequent doses must be reduced by an additional 50%. A maximum of 2 dose reductions are allowed. Participants who have a toxicity meeting the criteria for dose reduction following Cycle 2 will receive the protocol-specified dose of 50% of initiate dose for Cycle 3, i.e., they will not have an additional dose reduction for Cycle 3.
Receives: Drug: Loncastuximab Tesirine
Arm B: Moderate Hepatic ImpairmentExperimentalParticipants will receive loncastuximab tesirine in a standard 3+3 dose-escalation design. Initial dose will be 0.09 mg/kg Q3W for two cycles, then 0.045 mg/kg Q3W for subsequent cycles (1 cycle = 21 days). The highest dose possibly administered will be 0.15 mg/kg Q3W. Participants who have a toxicity meeting the criteria for dose reduction will have subsequent doses reduced by 50%. If the toxicity recurs, subsequent doses must be reduced by an additional 50%. A maximum of 2 dose reductions are allowed. Participants who have a toxicity meeting the criteria for dose reduction following Cycle 2 will receive the protocol-specified dose of 50% of initiate dose for Cycle 3, i.e., they will not have an additional dose reduction for Cycle 3.
Receives: Drug: Loncastuximab Tesirine
Arm C: Severe Hepatic ImpairmentExperimentalParticipants will receive loncastuximab tesirine in a standard 3+3 dose-escalation design. Initial dose will be 0.09 mg/kg Q3W for two cycles, then 0.045 mg/kg Q3W for subsequent cycles (1 cycle = 21 days). The highest dose possibly administered will be 0.15 mg/kg Q3W. Participants who have a toxicity meeting the criteria for dose reduction will have subsequent doses reduced by 50%. If the toxicity recurs, subsequent doses must be reduced by an additional 50%.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Loncastuximab Tesirine in people with Diffuse Large B-Cell Lymphoma and High-grade B-cell Lymphoma, run by ADC Therapeutics S.A. at 14 sites in 4 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 10 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: stopped early, as of the sponsor's last update on 20 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 14 sites in Brazil, South Korea, Taiwan, 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 stopped early (reason given: This decision to close the study was made following interactions with regulatory authorities and in consideration of the challenges associated with this patient population. No safety information contributed to this decision.). Results are not available in the source record.

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?

Number of Participants with Moderate or Severe Hepatic Impairment Who Experience a Dose-Limiting Toxicity (DLT) (time frame: Day 1 to Day 21 of Cycle 1, where a cycle is 21 days). 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 20 Jul 2026.
