Background:
The new drug LMP744 damages DNA. This causes cell death. Researchers want to see if it can
treat certain kinds of cancer. They want to understand how the drug works and how it affects
the body.
Objective:
To test the safety of LMP744 and find out the dose of the drug that can be safely given to
humans.
Eligibility:
Adults at least 18 years old who have metastatic solid tumors or lymphoma, which have
progressed after other treatment.
Design:
Participants will be screened with:
- Vital signs taken
- Blood and urine tests
- Heart tests
- Scans or ultrasound
Some participants will have a tumor sample taken 2 times. A small piece of tumor is removed
by a small needle. A scan or ultrasound will guide the process.
The study will be done in 28-day cycles.
Each cycle, participants will get the study drug in a vein for 60 minutes once a day for 5
days.
For day 1 of cycle 1, participants will be admitted to the clinic and have blood and urine
taken several times.
At the beginning of each cycle, participants will have a clinic visit and repeat some
screening tests. They will also do this twice in the middle of cycle 1 and once in the
middle of cycle 2.
After participants stop taking the study drug, they will be followed for 30 days. They may
give blood samples. They will be contacted by phone to see how they are doing.
Background:
- Indenoisoquinolines are non-camptothecin inhibitors of topoisomerase 1 (top1)
withimproved 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:
-To establish the safety, tolerability and the maximum tolerated dose (MTD) of LMP744 (NSC
706744) administered intravenously (IV) daily for 5 days (QD x 5) schedule in patients with
refractory solid tumors and lymphomas.
Secondary Objectives:
- Characterize the pharmacokinetic (PK) profile of LMP744.
- Evaluate the effect of LMP744 on markers of DNA damage ( >=H2AX, pNbs1, pATR, ERCC1,
RAD51) and epithelial-mesenchymal transition (EMT) in circulating tumor cells (CTCs)
and pre- and post- treatment tumor biopsies in patients at the expansion cohort.
- Assess preliminary antitumor activity of LMP744.
Eligibility:
-Adult patients must have histologically documented, relapsed solid tumors that are
metastatic or unresectable, or lymphoma which had progressed after all FDA-approved therapy,
therapy associated with overall survival benefit, or for which no standard of care therapy
exists.
Study Design:
- Cycle 1 and subsequent cycles: Patients will receive LMP744 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. Tumor biopsies will be optional during the
escalation phase and mandatory during the expansion phase and mandatory during the
expansion phase.
- ELIGIBILITY CRITERIA:
1. Patients must have histologically documented metastatic solid tumors which have
progressed after one line of therapy, or lymphoma which has progressed after all
FDA-approved therapy.
2. Patients must have measurable disease, defined as at least one lesion that can
be accurately measured in at least one dimension (longest diameter to be
recorded for non-nodal lesions and short axis for nodal lesions) as greater than
or equal to 20 mm (greater than or equal to 2 cm) with conventional techniques
or as greater than or equal to 10 mm (greater than or equal to 1 cm) with spiral
CT scan, MRI, or calipers by clinical exam.
3. Age greater than or equal to 18 years.
4. ECOG performance status less than or equal to 2
5. Life expectancy of greater than 3 months.
6. Patients must have normal organ and marrow function as defined below:
leukocytes greater than or equal to 3,000/mcL
absolute neutrophil count greater than or equal to 1,500/mcL
platelets greater than or equal to 100,000/mcL
total bilirubin within normal institutional limits
AST(SGOT)/ALT(SGPT) less than or equal to 2.5 (SqrRoot) institutional upper
limit of normal
creatinine within normal institutional limits
OR
creatinine clearance greater than or equal to 60 mL/min/1.73 m2 for patients
with creatinine levels above institutional normal.
7. Anticoagulation with low-molecular-weight heparin (LMWH) will be permitted.
Patients receiving treatment with warfarin or any of the NOACs (rivaroxaban,
apixaban, dabigatran, or edoxaban) will be given the option to switch to LMWH.
8. Patients must have recovered to grade 1 or baseline from adverse events (AEs)
and/or toxicity of prior chemotherapy or biologic therapy. They must not have
had chemotherapy, biologic therapy, or definitive radiotherapy within 4 weeks (6
weeks for nitrosoureas and mitomycin C) or 5 half-lives, whichever is shorter,
prior to entering the study. Palliative-intent radiotherapy (30 Gy or less) must
be completed at least 2 weeks prior to start of treatment, and may not be to a
lesion that is included as measurable disease. Patients must be greater than or
equal to 2 weeks since any investigational agent administered as part of a Phase
0 study (where a sub-therapeutic dose of drug is administered) at the PI s
discretion, and should have recovered to grade 1 or baseline from any
toxicities.
9. Patients receiving bisphosphonates for any cancer or undergoing androgen
deprivation therapy for prostate cancer are eligible for this therapy.
10. Prior therapy with topoisomerase I inhibitors is allowed.
11. HIV-positive patients are eligible provided the following criteria are met: CD4
count >350/mm3, an undetectable viral load, and not receiving prophylaxis
antibiotics.
12. The effects of LMP744 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; abstinence) prior to
study entry and for the duration of study participation. Should a woman become
pregnant or suspect she is pregnant while she or her partner is participating in
this study, she should inform her treating physician immediately. Women and men
treated or enrolled on this protocol must also agree to use adequate
contraception prior to the study, for the duration of study participation, and 4
months after completion of LMP744 administration.
13. Ability to understand and the willingness to sign a written informed consent
document.
14. Willingness to provide blood and new tumor biopsy samples for research purposes
if on the expansion phase of the study.
EXCLUSION CRITERIA:
1. Patients who are receiving any other investigational agents.
2. Patients with clinically significant illnesses which would compromise participation
in the study, including, but not limited to active or uncontrolled infection, immune
deficiencies, 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.
3. Patients with known brain metastases or carcinomatous meningitis 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 1 month after treatment of
the brain metastases. Patients on anti-seizure medications or steroid therapy may be
enrolled at the discretion of the Principal Investigator.
4. Pregnant women are excluded from this study because LMP744 is an agent with the
potential for teratogenic or abortifacient effects. Because there is an unknown but
potential risk for adverse events in nursing infants secondary to treatment of the
mother with LMP744, breastfeeding should be discontinued if the mother is treated.
INCLUSION OF WOMEN AND MINORITIES:
Both men and women of all races and ethnic groups are eligible for this trial.
