Brief Summary

Background:

- Belinostat is an experimental cancer treatment drug that works by helping to turn on genes that limit cell growth and survival of cancer cells. These genes are often switched off in tumors. Belinostat has been given to patients with different types of cancer to measure its safety and effectiveness, but it has not been given in a formal trial to cancer patients who have abnormal liver function. Because belinostat is processed by the liver, its safety and effectiveness needs to be established in individuals who have abnormal liver function. Researchers are interested in comparing the effects of belinostat as a cancer treatment drug in individuals with normal and abnormal liver function.

Objectives:

To test the safety and effectiveness of belinostat in individuals who have solid tumors and lymphomas and who also have abnormal liver function.
To compare the results of belinostat treatment in individuals with normal and abnormal liver function.

Eligibility:

Individuals at least 18 years of age who have been diagnosed with solid tumors or lymphomas that have not responded to standard treatment.
Individuals with normal liver function and varying degrees of abnormal liver function (mild, moderate, severe) are eligible.

Design:

Participants will be screened with a full medical history and physical examination, as well as blood and urine tests, and tumor imaging studies. Participants will then be divided into study groups based on their liver function.
Participants will receive belinostat in cycles of treatment. Except for cycle 1, all cycles will last 21 days. Cycle 1 will last 28 days. For cycle 1 only, participants will receive a single dose of belinostat 1 week before the regular 21-day treatment cycle starts.
In each cycle, participants will receive belinostat once a day for 5 days, and will be asked to keep a medication diary to record any side effects.
Participants will have regular clinic visits with blood and urine sample collection and imaging studies to evaluate the cancer's response to treatment.
Participants may continue to take belinostat for as long as the cancer responds to the treatment.

Detailed Description

Background:

Belinostat is a histone deacetylase (HDAC) inhibitor. HDACs are frequently deregulated in cancer cells, leading to an increase in deacetylation and the silencing of genes that normally control cell cycle arrest and apoptosis.
Belinostat has growth inhibitory activity in several malignancies in vitro and in vivo, both as a single agent and in combination with chemotherapeutic agents. Several Phase I and II clinical trials have been conducted to date in patients with solid tumor and hematologic malignancies; belinostat has been generally well tolerated.
Belinostat is metabolized in the liver and therefore, the safety and dosing of belinostat needs to be established in patients with varying degrees of hepatic dysfunction.

Objectives:

Establish the safety and tolerability of belinostat given on days 1 through 5 of 21-day cycles to patients with varying degrees of liver dysfunction.
Define the maximum tolerated dose (MTD) and recommended dose of belinostat given on days 1 through 5 of 21-day cycles to patients with varying degrees of liver dysfunction.
Evaluate the pharmacokinetics (PK) of one dose of belinostat (400 mg/m(2)) in patients with varying degrees of liver dysfunction.
Obtain preliminary evidence of anti-tumor activity at tolerable doses of belinostat in patients with varying degrees of liver dysfunction.
Measure direct versus indirect bilirubin levels and correlate these with observed toxicities, PK.

Eligibility:

-Adults with solid tumors or lymphomas whose disease has progressed after standard therapy or who have no acceptable standard treatment options. Patients with normal and varying degrees of hepatic dysfunction (mild, moderate, and severe) are eligible.

Study Design:

-Patients will be divided into 4 dose escalation cohorts based on their level of liver dysfunction. Belinostat will be administered intravenously (IV) over 30 minutes. On day -7 (Cycle 1 only), all patients will receive a single dose of 400 mg/m(2) belinostat. On days 1 through 5 of each cycle, patients will receive belinostat at a dose dependent on the level of hepatic dysfunction and dose level. Mild, moderate, and severe liver dysfunction cohorts will begin on dose level 1; patients with normal hepatic function will not have their dose escalated (see below). The total length of Cycle 1 will be 28 days; all other cycles will be 21 days. No more than 12 evaluable patients with normal hepatic function will be accrued.

Outcomes Module

Primary Outcomes

Measure	Description	Time Frame
Dose Limiting Toxicity (DLTs)	A DLT was defined as an adverse event deemed possibly, probably, or definitely related to administration of study drugs and met the following criteria: grade≥3 non-hematological toxicity (except grade ≥3 diarrhea, nausea, vomiting responsive to supportive therapy);grade≥3 rise in creatinine (except grade 3 able to be corrected to grade 1 or baseline with intravenous fluids within 24hrs); grade≥3 electrolyte toxicities (except those able to be corrected to grade 1 or baseline within 48hrs); grade 4 thrombocytopenia; grade 4 neutropenia for >5 days or febrile neutropenia; any neurotoxicity grade≥2 not reversible to grade 1 or baseline within 2wks; or any delay in treatment by ≥2wks due to treatment-related toxicity. Worsening liver function, as defined by a rise in serum bilirubin not related to tumor progression, was considered a DLT if a patient with mild dysfunction became severe for 1wk, or if a patient in either the moderate/severe groups had a >1.5x increase in bilirubin for 1 wk.	First cycle of therapy, 28 days.
Maximum Tolerated Dose (MTD) of Belinostat According to Degree of Liver Dysfunction	In order to maintain consistent dosing across the hepatic dysfunction groups, the dose recommended for cohorts with greater liver dysfunction could be no greater than the dose for cohorts of lesser dysfunction. In other words, it was assumed that a particular group would not tolerate a dose not tolerated by a group with lesser dysfunction and conversely, will tolerate a dose tolerated by a group with greater dysfunction. If a higher dose was tolerated in a group of greater dysfunction, but not in the group of lesser dysfunction, the lower dose would be recommended for both groups. The highest dose to be explored was no greater than the recommended dose for patients with normal liver function.	First cycle of therapy, 28 days
Number of Participants Experiencing Adverse Events Considered to be at Least Possibly Related to the Study Drug	The number of participants experiencing each adverse event by liver function cohort at each dose level. The grade refers to the severity of the Adverse Event. Grade 1 Mild; Grade 2 Moderate; Grade 3 Severe or medically significant but not immediately life-threatening; Grade 4 Life-threatening consequences; Grade 5 Death related to adverse event.

Secondary Outcomes

Measure	Description	Time Frame
Best Response	Radiologic response assessments by computed tomography (CT) scans were performed at baseline and every two cycles of treatment based on the Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1. Per RECIST v1.1 Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum diameters; Stable Disease (SD), neither sufficient shrinkage to qualify for a PR nor sufficient increase to qualify for Progression of Disease (PD), taking as reference the smallest sum diameters while on study; PD, >=20% increase in the sum of the longest diameter of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study) and an absolute increase of at least 5mm or the appearance of new lesions; Complete Response (CR), Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm.

Eligibility Module

Eligibility Criteria

INCLUSION CRITERIA:

Patients must have histologically or cytologically confirmed (at original diagnosis or subsequent recurrence or progression) solid tumor or lymphoma that is metastatic, unresectable, progressive, or recurrent, and for which standard curative or palliative measures do not exist or are no longer effective.
No radiation, major surgery, chemotherapy or biologic therapy within 4 weeks prior to entering the study (6 weeks for nitrosoureas or mitomycin C); greater than or equal to 2 weeks since any prior administration of study drug in an exploratory Investigational New Drug (IND)/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 Principal Investigator's (PI's) discretion. Patients must have recovered to at least eligibility levels due to adverse events and/or toxicity of prior chemotherapy or biologic therapy.
Age greater than or equal to 18 years. Because no dosing or adverse event data are currently available on the use of belinostat in patients < 18 years of age, children are excluded from this study but will be eligible for future pediatric Phase I single-agent trials.
Eastern Cooperative Oncology Group (ECOG) performance status less than or equal to 2 (Karnofsky greater than or equal to 60 percent.
Life expectancy of greater than 3 months.
Patients must have acceptable renal 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

serum creatinine within normal institutional limits OR creatinine clearance greater than or equal to 60 mL/min for patients with creatinine levels above institutional normal, as determined by a measured 24-hour creatinine clearance Baseline evaluations should be conducted within 7 days of treatment start date.

Patients with abnormal liver function will be eligible. Patients with active hemolysis should be excluded. No distinction will be made between liver dysfunction due to metastases and liver dysfunction due to other causes.
Patients with biliary obstruction for which a stent has been placed are eligible, provided the stent has been in place for at least 10 days prior to the first dose of belinostat and the liver function has stabilized. Two measurements at least 2 days apart that put the patient in the same hepatic dysfunction stratum will be accepted as evidence of stable hepatic function. There should be no evidence of biliary sepsis.
Patients with gliomas or brain metastases who require corticosteroids or anticonvulsants must be on a stable dose of corticosteroids and seizure free for 1 month prior to enrollment. Patients with known brain metastases should have had brain irradiation (whole brain or gamma knife) more than 4 weeks before starting the protocol. Note that patients should have had their steroids tapered to low dose (i.e., < 1.5 mg of dexamethasone/day).
The effects of belinostat on the developing human fetus are unknown. For this reason and because histone deacetylase (HDAC) inhibitors are known to be teratogenic, 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 participating in this study, she should inform her treating physician immediately.
Ability to understand and the willingness to sign a written informed consent document.

EXCLUSION CRITERIA:

Prior therapy with belinostat.
Patients may not be receiving any other investigational agents.
Patients with history of allergic reactions attributed to compounds of similar chemical or biologic composition to belinostat, including hydroxamate compounds or arginine.
Patients should not have taken valproic acid, another HDAC inhibitor, for at least 2 weeks prior to enrollment.
Patients with uncontrolled intercurrent illness including, but not limited to ongoing or active infection, or psychiatric illness/social situations that would limit compliance with study requirements.
Pregnant women are excluded from this study because belinostat is an HDAC inhibitor 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 belinostat, breastfeeding should be discontinued if the mother is treated with belinostat.
Human Immunodeficiency Virus (HIV) positive patients who are not on retroviral therapy will not be excluded from cohort 1, the normal liver function cohort. HIV positive patients who are not on retroviral therapy will be excluded from cohorts 2-4 because of confounding effects from potential complications from HIV and opportunistic infections.
HIV-positive patients on combination antiretroviral therapy are ineligible because of the potential for the increased risk of liver dysfunction from the antiretroviral therapies themselves and because of potential pharmacokinetics (PK) interactions with belinostat. Appropriate studies will be undertaken in these groups of patients when indicated.
Patients with significant cardiovascular disease (New York Heart Association Class III or IV cardiac disease), symptomatic congestive heart failure, myocardial infarction within the past 6 months, unstable angina, unstable arrhythmia or a need for anti-arrhythmic therapy (use of frequency adjusting medication for atrial fibrillation is allowed, if stable medication for at least last month prior to initiation of belinostat treatment and medication not listed as causing Torsades de Points), or evidence of acute ischemia on electrocardiogram (ECG). Marked baseline prolongation of Q wave, T wave (QT)/Corrected QT Interval (QTc) interval, e.g., repeated demonstration of a QTc interval > 450 msec; Long QT Syndrome; the required use of concomitant medication that may cause Torsades de Pointes.

Dose Limiting Toxicity (DLTs)

A DLT was defined as an adverse event deemed possibly, probably, or definitely related to administration of study drugs and met the following criteria: grade≥3 non-hematological toxicity (except grade ≥3 diarrhea, nausea, vomiting responsive to supportive therapy);grade≥3 rise in creatinine (except grade 3 able to be corrected to grade 1 or baseline with intravenous fluids within 24hrs); grade≥3 electrolyte toxicities (except those able to be corrected to grade 1 or baseline within 48hrs); grade 4 thrombocytopenia; grade 4 neutropenia for >5 days or febrile neutropenia; any neurotoxicity grade≥2 not reversible to grade 1 or baseline within 2wks; or any delay in treatment by ≥2wks due to treatment-related toxicity. Worsening liver function, as defined by a rise in serum bilirubin not related to tumor progression, was considered a DLT if a patient with mild dysfunction became severe for 1wk, or if a patient in either the moderate/severe groups had a >1.5x increase in bilirubin for 1 wk.

Forty patients were evaluable for dose-limiting toxicity; others came off study prior to the end of Cycle 1 and were not evaluable.
