About this study

Background:

  • Indenoisoquinolines are experimental cancer treatment drugs that damage the DNA in cells, resulting in cell death. Researchers have been studying these drugs and their usefulness in treating types of cancer that have not responded well to standard therapies like surgery or radiation.
  • LMP400 (NSC 743400) and LMP776 (NSC 725776) are indenoisoquinolines that have not been given to cancer patients before. These drugs have very similar chemical structures and work the same way, but researchers do not know which one will work best. More information is needed about how LMP400 and LMP776 are processed by the body and how effective they are in treating difficult-to-treat types of cancer.
Read more

Objectives:

  • To determine the maximum tolerated dose of LMP400 (NSC 743400) and LMP776 (NSC 725776).
  • To study how the body handles LMP400 and LMP776.
  • To evaluate the effectiveness of LMP400 and LMP776 as a treatment for tumors and lymphoma that have not responded to standard treatment.

Eligibility:

  • Individuals at least 18 years of age who have malignant solid tumors or Hodgkin s disease/non-Hodgkin lymphoma that has not responded to standard therapies.

Design:

  • Participants will receive either LMP400 or LMP776. The treatment cycle will be 28 days. On the first 5 days of each cycle, participants will receive intravenous doses of their specific study drug, followed by 23 days without the drug. The 28-day cycle will be repeated as long as the drug does not cause severe side effects and the cancer remains stable or improves. The study doctor may increase or decrease the dose of study drug depending on how well it is tolerated.
  • Blood, urine, and hair samples and skin and tumor biopsies will be collected during the first treatment cycle. Routine blood samples will be taken throughout the study.
  • Other tests, including additional blood and urine samples, computed tomography (CT) or other scans, and bone marrow samples, may be performed as directed by the study doctors.
Read the detailed description

Background:

  • Indenoisoquinolines are non-camptothecin inhibitors of topoisomerase 1 (top1) with improved characteristics over their predecessors. Indenoisoquinolines have better chemical stability, producing stable DNA-top1 cleavage complexes, and exhibit a preference for unique DNA cleavage sites, compared with their camptothecin counterparts.
  • They have demonstrated activity against camptothecin-resistant cell lines and produce DNA-protein crosslinks, which are resistant to reversal. They also show less or no resistance to cells overexpressing the ATP-binding cassette (ABC) transporters, ABCG2, and multidrug resistance (MDR-1).

Primary Objectives:

  • Define the maximum tolerated dose (MTD) of LMP400 (NSC 743400) and LMP776 (NSC 725776) administered intravenously (IV) daily for 5 days (QDx5).
  • Define the dose-limiting toxicities (DLTs) and toxicity profile associated with administration of LMP400 and LMP776.
  • Evaluate the effect of LMP400 and LMP776 on the pharmacodynamic (PD) endpoint, gamma-H2AX, in tumor biopsy pre- and post-treatment. In particular, compare the PD response, defined as the mean percent nuclear area that is gamma-H2AX positive (%NAP) in tumor biopsies, at the MTD for LMP400 and LMP776, and the toxicity profile versus PD dose-response relationship.

Secondary Objectives:

  • Obtain preliminary evidence of anti-tumor activity of LMP400 and LMP776.
  • Characterize the pharmacokinetic (PK) profile of LMP400 and LMP776.

Eligibility:

-Adult patients must have histologically confirmed relapsed solid tumor malignancy or lymphoma that is metastatic or unresectable for which standard curative measures do not exist or are associated with minimal patient survival benefit.

Study Design:

  • Cycle 1 and subsequent cycles: Patients will be randomized to receive either LMP400 or LMP776 administered IV QD over 1 hour on days 1-5 followed by 23 days without drug (28-day cycle).
  • PK and PD samples will be collected in cycle 1 only. Tumor biopsies will not be collected during the escalation phase; however, tumor biopsies will be mandatory during the expansion phase.

A Phase 1 study testing LMP400 and LMP776 in people with Neoplasms and Lymphoma, run by National Cancer Institute (NCI) 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 23 inclusion and 3 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 17 Jul 2025. 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 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 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 (time frame: 1 cycle (28 days)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01051635, which also lists 2 linked publications.

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 17 Jul 2025.
