Tazemetostat in Treating Patients With Metastatic or Unresectable Solid Tumors or B-Cell Lymphomas With Liver Dysfunction

Withdrawn before enrolling · Phase 1

Conditions studied: Ann Arbor Stage III B-Cell Non-Hodgkin Lymphoma, Ann Arbor Stage IV B-Cell Non-Hodgkin Lymphoma, Metastatic Malignant Solid Neoplasm, Stage III Hepatocellular Carcinoma AJCC v7, Stage IIIA Hepatocellular Carcinoma AJCC v7, Stage IIIB Hepatocellular Carcinoma AJCC v7, Stage IIIC Hepatocellular Carcinoma AJCC v7, Stage IV Hepatocellular Carcinoma AJCC v7, Stage IVA Hepatocellular Carcinoma AJCC v7, Stage IVB Hepatocellular Carcinoma AJCC v7, Unresectable Solid Neoplasm

In brief

This phase I trial studies the best dose and side effects of tazemetostat in treating patients with solid tumors or B-cell lymphomas with liver dysfunction that have spread to other places in the body or cannot be removed by surgery. Tazemetostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

You may qualify if…

Patients must have histologically and/or cytologically confirmed solid tumors or B cell lymphoma that are metastatic or unresectable and for which standard treatment options do not exist; patients with hepatocellular carcinoma are eligible without pathological diagnosis if diagnosed on the basis of blood work and imaging
Patients with evaluable disease will be eligible
All patients must have completed any prior chemotherapy, targeted therapy and major surgery, >= 28 days before study entry; for daily or weekly chemotherapy without the potential for delayed toxicity, a washout period of 14 days may be acceptable, and questions related to this can be discussed with study principal investigator
Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60%)
Life expectancy of greater than 3 months
Able to swallow and retain orally-administered medication and does not have any clinically significant gastrointestinal abnormalities that may alter absorption such as malabsorption syndrome or major resection of the stomach or bowels
All prior treatment-related toxicities must be Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 grade =< 1 (except alopecia) at the time of enrollment
Leukocytes >= 3,000/mcL
Absolute neutrophil count >= 1,500/mcL
Platelets >= 100,000/mcL
Hemoglobin >= 90 g/L (9.0 g/dL)
Creatinine within normal institutional limits OR calculated creatinine clearance >= 60 mL/min/1.73 m\^2 (Cockcroft-Gault formula) for patients with creatinine levels above institutional normal
Patients with abnormal hepatic function will be eligible and will be grouped according to criteria; patients with active hemolysis should be excluded; no distinction should be made between liver dysfunction due to metastases and liver dysfunction due to other causes; this data will be captured in the case report form (CRF); registration laboratory investigations will be used to assign a patient to a hepatic function group; hepatic function tests should be repeated within 24 hours prior to starting initial therapy and may result in patients' group assignment being altered if different to registration test results
For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods that result in a failure rate of < 1% per year during the treatment period and for 30 days after tazemetostat discontinuation
A woman is considered to be of childbearing potential if she is postmenarchal, has not reached a postmenopausal state (>= 12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus)
Examples of contraceptive methods with a failure rate of < 1% per year include bilateral tubal ligation, male sterilization, established, proper use of hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices
Female subjects who use hormonal contraceptives should use an additional barrier method of birth control while on study treatment and for 30 days after discontinuation of study treatment
The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical study and the preferred and usual lifestyle of the patient; periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception
For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures and agreement to refrain from donating sperm, as defined below:
With female partners of childbearing potential or pregnant female partners, men must remain abstinent or use a condom during the treatment period and for at least 4 months after the last dose of study drug; men must refrain from donating sperm during this same period; in addition, female partners of male subjects should adhere to the following:
Intrauterine device (IUD)(must provide medical documentation of IUD)
Hormonal contraceptive (partner must be on a stable dose of the same hormonal contraceptive product for at least 4 weeks before receiving study drug) AND a condom (hormonal contraceptives must be supplemented with condoms)
The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical study and the preferred and usual lifestyle of the patient; periodic abstinence and withdrawal are not acceptable methods of contraception
Females of childbearing potential must have a negative serum pregnancy test at screening
Ability to understand and the willingness to sign a written informed consent document

You may not qualify if…

Symptomatic or untreated leptomeningeal or brain metastases or spinal cord compression as documented by computed tomography (CT) or magnetic resonance imaging (MRI) scan, analysis of cerebrospinal fluid or neurological exam; patients with primary glioblastoma multiforme are excluded
Radiation therapy in the last 14 days; palliative radiation to a localized area without residual toxicity requires a washout of greater than 7 days
Clinically significant bleeding diathesis or coagulopathy, including known platelet function disorders; patients on anticoagulation with low molecular weight heparin are allowed
Known hypersensitivity to any of the components of tazemetostat
History of allergic reactions attributed to compounds of similar chemical or biologic composition to tazemetostat
Concurrent investigational agent or anticancer therapy
Note: megestrol [Megace] if used as an appetite stimulant is allowed
Concurrent treatment with bisphosphonates is permitted; however, treatment must be initiated prior to the first dose of study therapy; prophylactic use of bisphosphonates in patients without bone disease is not permitted, except for the treatment of osteoporosis
The concurrent use of all herbal supplements is prohibited during the study (including, but not limited to, St. John's wort, kava, ephedra [ma huang], ginkgo biloba, dehydroepiandrosterone [DHEA], yohimbe, saw palmetto, or ginseng)
Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, clinically significant bleeding diathesis or coagulopathy, including known platelet function disorders, symptomatic congestive heart failure, unstable angina pectoris, clinically significant cardiac arrhythmias, or psychiatric illness/social situations that would limit compliance with study requirements
Active hepatitis B virus (HBV; hepatitis B surface antigen [HepBsAG] positive [+ve] and IgM anti-hepatitis B virus core antibody [HBc]), or hepatitis C virus (HCV; detectable HCV ribonucleic acid [RNA]) infection; patients with chronic or cleared HBV and HCV infection are eligible
Patients with known human immunodeficiency virus (HIV) infection are eligible if being treated with non-interacting antiretroviral (ARV) agents or be willing to stop ARV for the protocol
Treatment with strong inhibitors or inducers of CYP3A are prohibited from 14 days prior to the first dose of tazemetostat to the end of the study
Active gastrointestinal tract disease with malabsorption syndrome or unable to swallow oral medications
Any condition or medical problem in addition to the underlying malignancy and organ dysfunction that the investigator feels would pose unacceptable risk
Has thrombocytopenia, neutropenia, or anemia of grade >= 3 (per CTCAE 5.0 criteria) or any prior history of myeloid malignancies, including myelodysplastic syndrome (MDS)
Has abnormalities known to be associated with MDS (e.g. del 5q, chr 7 abn) and multiple primary neoplasms (MPN) (e.g. JAK2 V617F) observed in cytogenetic testing and DNA sequencing
Has a prior history of T-acute lymphoblastic lymphoma (T-LBL)/T-acute lymphoblastic leukemia (ALL)
