Summary

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.

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.

Conditions

Interventions

DRUG

LMP400

Indenoisoquinolines are non-camptothecin inhibitors of topoisomerase 1 with improved characteristics such as better chemical stability, producing stable DNA-top1 cleavage complexes, and exhibiting a preference for unique DNA cleavage sites compared with their camptothecin counterparts.

LMP776

Indenoisoquinolines are non-camptothecin inhibitors of topoisomerase 1 with improved characteristics such as better chemical stability, producing stable DNA-top1 cleavage complexes, and exhibiting a preference for unique DNA cleavage sites compared with their camptothecin counterparts.
