PU-H71 in Patients With Solid Tumors and Low-Grade Non-Hodgkin's Lymphoma That Have Not Responded to Standard Treatment

• Status: Terminated
• Trial end date: 2014-09-03
• Target enrollment: 0
• Participant gender: All

Summary

Background:

• PU-H71 is an experimental drug used to treat cancer. It works by blocking a protein in tumors. When this protein is blocked, it affects other proteins inside the cell that cancers need to grow. Researchers want to study whether PU-H71 is a safe and effective way to treat solid tumors and non-Hodgkin's lymphoma.

Objectives:

• To evaluate the safety and effectiveness of PU-H71 in solid tumors and non-Hodgkin's lymphoma that have not responded to standard treatments.

Eligibility:

• Individuals at least 18 years of age who have solid tumors or non-Hodgkin's lymphoma that have not responded to standard treatments.

Design:

• Patients will be screened with a physical exam, medical history, blood tests, and imaging studies.

• Patients will receive PU-H71 as a 1-hour dose on days 1 and 8 of a 21-day cycle of treatment. The first treatment cycle will be done in the hospital so that patients can be monitored. The next treatment cycles will be done on an outpatient basis.

• Patients will have blood and urine tests and eye exams.

• Patients will provide tumor samples for study.

• Patients will have imaging studies to monitor tumor response to treatment.

• Patients will continue to take PU-H71 for as long as side effects remain tolerable and their tumor or lymphoma does not worsen. Study researchers may adjust the dose if needed.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: National Cancer Institute (NCI)
• Treatments: 9H-purine-9-propanamine, 6-amino-8-((6-iodo-1,3-benzodioxol-5-yl)thio)-N-(1-methylethyl)-

Criteria

• INCLUSION CRITERIA:

• Patients must have histologically documented (confirmed at the Laboratory of Pathology, National Cancer Institute (NCI)) solid tumor malignancy or low-grade non-Hodgkin's lymphoma that is metastatic or unresectable, for which standard curative measures do not exist, or whose disease has progressed or recurred following at least one line of standard therapy.

• Patients must have measurable or evaluable disease.

• Patients must have completed any chemotherapy, radiation therapy, or biologic therapy greater than or equal to 4 weeks prior to entering the study (6 weeks for nitrosoureas or mitomycin C).

Patients must be greater than or equal to 2 weeks since any prior administration of a study drug in a Phase 0 study (also referred to as a pre-Phase I study where a sub-therapeutic dose of drug is administered). Patients must have recovered to eligibility levels from prior toxicity or adverse events. Patients receiving bisphosphonates for any cancer are eligible to participate.

• Age greater than or equal to 18 years.

• An Eastern Cooperative Oncology Group (ECOG) performance status less than or equal to 2.

• Life expectancy > 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 less than or equal to 1.5 times institutional upper limit of normal (ULN)

• Aspartate aminotransferase (AST)serum glutamic oxaloacetic transaminase (SGOT)/alanine aminotransferase (ALT) serum glutamic pyruvic transaminase(SGPT) less than or equal to 2.5 times institutional ULN

• Creatinine <1.5 times ULN; OR

• Measured creatinine greater than or equal to 60 mL/minute for patients with clearance creatinine levels greater than or equal to 1.5 times ULN

• The effects of PU-H71 on the developing human fetus are unknown. For this reason, women of childbearing 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 completion of study. Women of childbearing potential must have a negative pregnancy test within 72 hours of enrollment in order to be eligible. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in the study, the treating physician should be notified immediately. Because there is an unknown but potential risk to nursing infants secondary to treatment of the mother with PU-H71, breastfeeding should be discontinued if the mother is treated with PU-H71.

• During the expansion phase of the protocol, patients must have:

• Disease amenable to biopsy

• Willingness to undergo pre- and post-treatment tumor biopsies

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

EXCLUSION CRITERIA:

• 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 3 months after treatment of the brain metastases.

• Patients with clinically significant intercurrent illnesses, including but not limited to, symptomatic congestive heart failure, unstable angina pectoris, uncontrolled cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

• Corrected QT interval (QTc) > 450 msec for men and > 470 msec for women.

• Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetics (PK) interactions with PU-H71.

• Pregnant women are ineligible because the effects of PU-H71 on the developing human fetus are unknown. Breastfeeding should be discontinued if the mother is treated with PU-H71 since there is an unknown but potential risk for adverse events in nursing infants.
