- 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.


- 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.


- 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.


- 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.

-Patients must have histologically documented (confirmed at the Laboratory of Pathology, NCI), relapsed solid tumor malignancy or Hodgkin s disease/non-Hodgkin lymphoma that is metastatic or unresectable for which standard curative measures do not exist, or are associated with minimal patient survival benefit.

- Patients must have measurable or evaluable disease.

- Patients must have recovered to at least eligibility levels due to adverse events (AEs) and/or toxicity of prior chemotherapy or biologic therapy. They must not have had chemotherapy or biologic therapy within 4 weeks (6 weeks for nitrosoureas and mitomycin C, or 2 months for UCN-01), or therapy with tyrosine kinase inhibitors within 5 times the half-life of the inhibitors prior to entering the study. Patients must be (Bullet)2 weeks since any investigational agent administered as part of a Phase 0 study (also referred to as an early Phase I study or pre-Phase I study where a sub-therapeutic dose of drug is administered) at the PI s discretion, and should have recovered to eligibility levels from any toxicities.

-Patients must have recovered to at least a Grade less than or equal to toxicity eligibility levels due to adverse events (AEs) and/or toxicity of prior chemotherapy or biologic therapy. They must not have had chemotherapy or biologic therapy within 4 weeks (6 weeks for nitrosoureas and mitomycin C, or 2 months for UCN-01), or therapy with tyrosine kinase inhibitors within 5 times the half-life of the inhibitors prior to entering the study. Patients must be greater than or equal to 2 weeks since any prior administration of study drug in an exploratory IND/Phase 0 study. Patients must be greater than or equal to 1 month since completion of any prior radiation (greater than or equal to 2 weeks for palliative radiation therapy). However, patients receiving bisphosphonates for any cancer or undergoing androgen deprivation therapy for prostate cancer are eligible for this therapy. Prior therapy with topoisomerase I inhibitors is allowed.

-Age greater than or equal to 18 years.

-The Eastern Cooperative Oncology Group (ECOG) performance status less than or equal to 2 (Karnofsky greater than or equal to 60%).

-Life expectancy greater than 3 months.

-Patients must have normal or adequate organ and marrow function as defined below:

--Absolute neutrophil count greater than or equal to 1,500/microL

--Platelets greater than or equal to 100,000/microL

--Total bilirubin* within less than or equal to 1.5 normal institutional limits

--AST (SGOT)/ALT (SGPT) less than or equal to 2.5 times institutional upper limit of normal

--Creatinine less than 1.5 times upper limit of normal


--Creatinine clearance greater than or equal to 60 mL/minute for patients with (measured) creatinine levels greater than or equal to 1.5 times upper limit of normal

*we will allow patients with Gilbert s syndrome with total bilirubin up to 2.5 mg/dL

-The effects of indenoisoquinolines on the developing human fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control or abstinence) prior to study entry, for the duration of study participation, and for 2 months after discontinuation from the study. Women of child bearing potential must have a negative pregnancy test in order to be eligible. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. Because there is an unknown but potential risk to nursing infants secondary to treatment of the mother with indenoisoquinolines, breastfeeding should be discontinued if the mother is treated with indenoisoquinolines.

-Willingness to undergo skin biopsies.

-At the point when tumor biopsies become mandatory rather than optional, disease amenable to biopsy and willingness to undergo biopsies or patient will be undergoing a procedure due to medical necessity during which the tissue may be collected, or tumor biopsy tissue from a previous research study or medical care is available for submission at registration. Criteria for the submission of tissue are:

--Tissue must have been collected within 3 months prior to registration

--Patient has not received any intervening therapy for their cancer since the collection of the tumor sample

--Tumor tissue must meet the minimum requirements outlined in Section 9.1.

-Ability to understand and the willingness to sign a written informed consent document.


- Patients receiving any other investigational agents.

- Patients with known brain metastases are excluded from this clinical trial, with the exception of patients whose brain metastatic disease status has remained stable for greater than or equal to 2 months after treatment of the brain metastases, without steroids or anti-seizure medications. These patients may be enrolled at the discretion of the principal investigator.

- Patients with clinically significant illnesses which could compromise participation in the study, including, but not limited to, active or uncontrolled infection, immune deficiencies, known HIV infection requiring antiretroviral therapy, Hepatitis B, Hepatitis C, uncontrolled diabetes, uncontrolled hypertension, symptomatic congestive heart failure, unstable angina pectoris, myocardial infarction within the past 6 months, uncontrolled cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
