Background:

Mature T-cell malignancies (TCMs) are a rare group of cancers that usually do not have effective treatments or cures. Because of this, participants with TCMs often relapse and have a poor overall prognosis. This trial is testing if combining several drugs against TCMs can be a more effective.

Primary Objective:

To test if the combination of romidepsin, CC-486 (5-azacitidine), dexamethasone, and lenalidomide (RAdR) can be given safely to participants with relapsed or treatment refractory TCM.

Other (Secondary) Objective:

Measure the activity of this combination treatment.

Eligibility:

People age 18 and older who have a failed or relapsed after standard treatments for mature TCMs.

Design:

Participants will be screened for eligibility by performing the following tests or procedures:

Physical exam

Medical history

Medicine review

Blood and urine tests

Symptom review

Bone marrow examination

Total Body imaging scans or x-rays

Tumor biopsy

Participants will have blood tests during treatment to make sure their blood cell counts are okay.

Romidepsin is infused through an intravenous (IV) placed in one of the veins usually in the arm. Lenalidomide, dexamethasone, and CC-486 (5-azacitidine) are pills or capsules taken by mouth.

Participants are asked to keep a diary of when they take their pills to make sure they are taking these medicines properly.

Participants will have tumor imaging scans after every 2nd cycle (or 6 weeks) to check if the treatment is working. If the doctors are concerned the cancer has spread to the brain and/or spine, they will have scans of the area(s) and a sampling of the fluid around the brain/spine which is obtained through a small needle inserted into the lower part of the back for a short time to collect the fluid. This procedure is called a spinal tap or lumbar puncture.

Participants who have tumor in their skin will have repeat exams of their skin and sometimes photographs taken of these areas to see if the treatment is working.

Participants will also be asked to give blood, saliva, and sometimes have optional biopsies of their tumor where these tests are done for research purposes.

After they have completed the protocol treatment (6 cycles), they will be asked to return to clinic 30 days after treatment has ended, then every other month (or 60 days) for the first 6 months, then every 3 months (90 days) for 2 years, and then every 6 months for years 2 to 4 after completing treatment. After 4.5 years, they will be seen once a year.

Background:

• Mature T-cell malignancies (TCM) are rare and heterogeneous group of leukemias and lymphomas accounting for 5 to 10% of all lymphomas in the US
• Patients with systemic TCM are most commonly treated with a CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone)-like regimens, that produce long-term progression-free survival in about 30% of these cases
• Patients with relapsed/refractory (R/R) TCM have very poor prognosis with median overall survival of less than 1 year. Treatment options for R/R TCM are very few and of limited efficacy, thus novel treatment strategies are urgently needed.
• Mutations in epigenetic regulators are common in aggressive TCMs and standard treatment with histone deacetylase inhibitors (HDACi) such as romidepsin show modest clinical activity with single agent the overall response (ORR) around 25%
• Combination of romidepsin and 5-azacitidine (hypomethylating agents) was synergistic in preclinical models, and has demonstrated high clinical activity with an ORR of 79%
• Many TCMs rely on The Ikaros-dependent nuclear factor κB (NF-κB)/interferon regulatory factor 4 (IRF4) signaling pathway to maintain proliferation, which is why lenalidomide, which induces degradation of Ikaros and downregulates IRF4, has single agent activity in R/R TCM with overall response rate (ORR) of 26% to 42%, depending on the subtype.
• Lenalidomide synergizes with romidepsin and enhances tumor cell death in TCM cell lines, predicting that the addition of lenalidomide to the established romidepsin/ CC-486 (5-azacitidine) combination will further improve efficacy.

Objectives:

-To determine the safety and toxicity profile and the maximum tolerated dose (MTD) of the four-drug combination of CC-486 (5-azacitidine), romidepsin, lenalidomide and dexamethasone in patients with TCM

Eligibility:

• Refractory/relapsed TCM (excluding in Cutaneous T-Cell Lymphoma) defined as follows:

  • Patients with systemic disease

• Age >= 18 years of age

• Eastern Cooperative Oncology Group performance status of <= 2 (or <= 3 if decrease is due to the disease)

• Histologically or cytologically confirmed relapsed and/or refractory mature TCM

• Adequate organ and marrow function

Design:

• Open-label, single-center, uncontrolled Phase 1 study
• 3 + 3 design will be used to determine the maximum tolerated dose (MTD) of dose-escalated lenalidomide with fixed dose of romidepsin and CC-486 (5-azacitidine)
• An expansion cohort of 9 patients will be evaluated at the MTD

• For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated.
• Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load.
• History of inflammatory bowel disease (e.g., Crohn's disease, ulcerative colitis), celiac disease (i.e., sprue), prior gastrectomy or upper bowel removal, or any other gastrointestinal disorder or defect that would interfere with the absorption, distribution, metabolism or excretion of the study drug and/or predispose the subject to an increased risk of gastrointestinal toxicity.
• Clinically significant (i.e., active) cardiovascular disease: cerebral vascular accident/stroke (< 6 months prior to enrollment), myocardial infarction (< 6 months prior to enrollment), unstable angina, congestive heart failure (>= New York Heart Association Classification Class II), congenital long QT syndrome, or other serious cardiac arrhythmia including 2nd degree atrio ventricular (AV) block type II, 3rd degree AV block, or bradycardia (ventricular rate less than 50 beats/min).

• Other severe acute or chronic medical conditions including psychiatric conditions such as recent (within the past year) or active suicidal ideation or behavior; or laboratory abnormalities that may increase the risk associated with study participation or study treatment administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for entry into this study.
• Pregnant or lactating women. Pregnant women are excluded from this study because lenalidomide is a Class X 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 lenalidomide, breastfeeding should be discontinued if the mother is treated with lenalidomide. These potential risks may also apply to other agents used in this study.
