Subcutaneous Recombinant Human IL-15 (s.c. rhIL-15) and Alemtuzumab for People With Refractory or Relapsed Chronic and Acute Adult T-cell Leukemia (ATL)

NCT02689453

Description:

Background: Adult T-cell leukemia (ATL) is a rare blood cancer. Researchers want to see if a combination of two drugs - recombinant human interleukin 15 (rhIL-15) and alemtuzumab - is a better treatment for ATL. Objectives: To test if giving rhIL-15 combined with alemtuzumab improves the outcome of therapy for ATL. Also, to determine the safe dose of this combination and identify side effects and effects on the immune system. Eligibility: Adults 18 years and older with chronic or acute ATL who have not been helped by other treatments. Design: Participants will be screened with tests that are mostly part of their usual cancer care. They will sign a separate consent form for this. Weeks 1 and 2: Participants will have a total of 10 visits. They will: - Get rhIL-15 under the skin by needle. - Have a physical exam and vital signs measured. - Give blood samples. - Answer questions about their health and their medicines. Week 3: Participants will stay in the clinic. They will: - Get alemtuzumab infusions in a vein through a small catheter on days 1, 2, 3, and 5.. - Take medicines to decrease side effects. - Have a computed tomography (CT) scan to evaluate the treatment. - Have a physical exam and vital signs measured. - Give blood samples. Answer questions about their health and medicines. Weeks 4, 5, and 6 will repeat week 3, without the CT scan. Some patients will just have outpatient visits these weeks. After treatment, participants will have follow-up visits every few months for up to 2 years. At these visits, participants will give blood samples and have CT scans.

Detailed Description

      Background:

        -  A previous trial alemtuzumab (CAMPATH-1) in patients with chronic, acute and
           lymphomatous subtype HTLV-1 associated ATL showed appreciable initial activity but no
           clear long-term impact.

        -  Antibody dependent cellular cytotoxicity (ADCC) with polymorphonuclear neutrophils
           (PMNs), monocytes and natural killer (NK) cells acting as the effector cells is
           alemtuzumab s primary in vivo mechanism of action for depleting malignant leukemic or
           lymphomatous cells.

        -  The immunologic effects of Interleukin-15 (IL-15), a stimulatory cytokine that promotes
           the differentiation and activation of NK cells, monocytes and long-term CD8+ memory
           Tcells, has been assessed in several phase I trials in cancer patients.

        -  Administration of recombinant human (rh) IL-15 as an intravenous bolus (IVB), continuous
           intravenous infusion (CIV) or subcutaneous injections (SC) into adult cancer patients
           has produced 5 to 50 fold expansion in the number of circulating NK cells at well
           tolerated doses in these patients.

        -  Preclinical murine lymphoid malignancy models have shown efficacy from the
           administration of IL-15 and monoclonal antibodies, with improved survival compared to
           controls.

      Objective:

      -To determine the safety, toxicity profile and the maximum tolerated dose (MTD) of s.c.
      rhIL-15 in combination with standard three times per week IV alemtuzumab treatment.

      Eligibility:

        -  Age greater than or equal to 18 years old

        -  ECOG Performance Status less than or equal to 1

        -  Diagnosis of adult T-cell leukemia (HTLV-1 associated, chronic or acute), peripheral
           T-cell lymphoma (angioimmunoblastic, hepatosplenic, or not otherwise specified),
           cutaneous T-cell lymphoma (Stage III or IV, with leukemia involvement or erythrodemia),
           or T-cell prolymphocytic leukemia (T-PLL)

        -  Measurable or evaluable disease

        -  Adequate organ and bone marrow function as defined in the protocol.

      Design:

        -  This is a single institution nonrandomized Phase I dose escalation study evaluating
           increasing doses of SC rhIL-15 in combination with alemtuzumab using a standard 3 + 3
           dose escalation.

        -  Treatment will include s.c. rhIL015 daily (M-F) weeks 1 and 2 (dose levels 0.5- 2
           mcg/kg/dose), followed by IV alemtuzumab beginning in week 3 (escalating doses followed
           by standard dosing in weeks 4-6).

        -  Up to 30 patients will be enrolled in this study.

        of T cells produced by alemtuzumab may have adverse effects on HIV-positive individuals.

          -  Concurrent anticancer therapy (including other investigational agents).

          -  History of severe asthma or presently on chronic inhaled corticosteroid medications
             (patients with a history of mild asthma not requiring corticosteroid therapy are

          -  Pregnant or nursing patients.

          -  Patients who have previously received alemtuzumab are ineligible. NOTE: Patients with
             relapsed T-PLL who have achieved at least a partial response to prior alemtuzumab are
             eligible.

          -  Uncontrolled intercurrent illness including, but not limited to, ongoing or active
             infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac

             substance abuse, or psychiatric illness/social situations that, in the view of the
             Investigator, would preclude safe treatment or the ability to give informed consent
             and limit compliance with study requirements.
