Study summary

This phase I trial studies the side effects and best dose of anti-inducible T-cell co-stimulator (ICOS) monoclonal antibody MEDI-570 in treating patients with peripheral T-cell lymphoma follicular variant or angioimmunoblastic T-cell lymphoma that has returned after a period of improvement (relapsed) or has not responded to previous treatment (refractory). Immunotherapy with monoclonal antibodies, such as anti-ICOS monoclonal antibody MEDI-570, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread.

Read the detailed description

PRIMARY OBJECTIVE:

I. To determine the safety, maximum tolerated dose and recommended phase II dose (RP2D) of anti-ICOS monoclonal antibody MEDI-570 (MEDI-570) in patients with refractory/relapsed peripheral T-cell lymphoma-not otherwise specified (PTCL-NOS), angioimmunoblastic T-cell lymphoma (AITL), follicular lymphoma, mycosis fungoides (MF) and cutaneous T-cell lymphomas (CTCL).

SECONDARY OBJECTIVES:

I. To evaluate the pharmacokinetic profile of MEDI-570. II. To evaluate the overall response rate (ORR) and progression free survival (PFS) of MEDI-570 at all dose levels and in a 10-patient expansion cohort at the maximum tolerated dose (MTD).

III. To determine short and long term effects of MEDI-570 at all dose levels on the immune system and on T-cell lymphocyte subsets.

IV. To determine the relationship between ICOS expression on tumor cells and response to MEDI-570.

EXPLORATORY OBJECTIVE:

I. To evaluate biomarkers of response and resistance to MEDI-570 in the study population.

OUTLINE: This is a dose-escalation study.

Patients receive anti-ICOS monoclonal antibody MEDI-570 intravenously (IV) over 1-4 hours on day 1. Treatment repeats every 21 days for up to 8 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days and then every 6 weeks for 12 weeks.

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

Exclusion criteria

Exclusion Criteria:

  • Patients who are receiving any other investigational agents
  • Patients with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to MEDI-570 or history of anaphylaxis to any biological component
  • Any history or evidence of opportunistic infection within 6 months of screening including tuberculosis, severe cytomegalovirus (CMV) or herpetic infections (such as disseminated herpes, herpes encephalitis, ophthalmic herpes)
  • Evidence of active infection by hepatitis B and/or C; active viral infection by hepatitis B and hepatitis C could be associated with cytopenias (due to hypersplenism or due to the active virus itself), which could add further risk when a potential immunosuppressive medication is used; for patients with hepatitis B treated with anti-virals to undetectable viral load, and for patients with hepatitis C with undetectable ribonucleic acid (RNA) levels and no evidence of liver damage, enrollment may be considered and should discuss first with study's principal investigator
  • History of human immunodeficiency virus (HIV) infection; the human immunodeficiency virus (HIV) depletes CD4 T-cells and could also have a role in T-cell anergy; since MEDI-570 preferentially affects CD4 T-cell numbers and function, and the resultant immunosuppression by this agent can be prolonged, exposing HIV patients to MEDI-570 will place them in an unnecessary risk of developing infections due to an underlying acquired cellular immunity defect
  • History of primary immunodeficiency
  • Receipt of live or live attenuated vaccine within 12 weeks prior to enrollment
  • All potential patients must undergo a tuberculosis (TB) test prior to study entry to rule out active or latent tuberculosis (either purified protein derivative [PPD] or QuantiFERON-TB Gold, whichever is preferred and available at the institution); patients with a history of TB (even if treated), or evidence of active or latent TB, are excluded; the diagnosis of active TB is defined per current guidelines; patients with a positive TB test (e.g. PPD or QuantiFERON-TB Gold) will be excluded; patients with history of Bacille-Calmette-Guerin (BCG) vaccination will be tested with QuantiFERON-TB Gold test in order to rule out exposure to TB
  • Patients who have undergone allogeneic stem cell transplantation
  • Patients who have undergone autologous stem cell transplantation within 3 months from study entry
  • Major surgery within 30 days prior or during the study period
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
  • Pregnant women are excluded from this study due to the potential toxicity in pre-clinical reproductive studies; in addition, there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with MEDI-570; breastfeeding should be discontinued if the mother is treated with MEDI-570
  • Patients with active, known, or suspected autoimmune disease, except in these conditions:

    • Participants with well-controlled asthma and/or mild allergic rhinitis (seasonal allergies) are eligible
    • Participants with the following disease conditions are also eligible:

      • Vitiligo,
      • Type 1 diabetes mellitus
      • Residual hypothyroidism due to autoimmune condition only requiring hormone replacement
      • Euthyroid participants with a history of Grave's disease (participants suspected autoimmune thyroid disorders must be negative for thyroglobulin and thyroid peroxidase antibodies and thyroid stimulating immunoglobulin prior to first dose of study drug)
      • For patients with ITP (idiopathic thrombocytopenic purpura) or AIHA (autoimmune hemolytic anemia), a case by case discussion with study principal investigator (PI) may be considered
      • Patients not receiving systemic therapy (i.e., systemic steroids or biologic therapy with disease modifying anti-rheumatic drugs [DMARDs]) within 2 years can be also eligible
  • Patients with a weight of \< 39 kg

Summary statistics, such as the mean, median, counts and proportion, will be used to describe patients' clinical characteristics. For all statistical tests, two-sided tests will be performed and no p-value adjustment performed due to the exploratory nature of these tests. A p-value of 0.05 or less will be considered statistically significant.

    Time frame: Up to 36 weeks

  3. Progression-free survival

    Summary statistics, such as the mean, median, counts and proportion, will be used to describe patients' clinical characteristics. For all statistical tests, two-sided tests will be performed and no p-value adjustment performed due to the exploratory nature of these tests. A p-value of 0.05 or less will be considered statistically significant.

    Time frame: Up to 12 weeks after completion of study treatment

  4. Immunogenicity

    Summary statistics, such as the mean, median, counts and proportion, will be used to describe patients' clinical characteristics. For all statistical tests, two-sided tests will be performed and no p-value adjustment performed due to the exploratory nature of these tests. A p-value of 0.05 or less will be considered statistically significant.

    Time frame: Up to 36 weeks

  5. Overall survival (OS)

    Summary statistics, such as the mean, median, counts and proportion, will be used to describe patients' clinical characteristics. For all statistical tests, two-sided tests will be performed and no p-value adjustment performed due to the exploratory nature of these tests. A p-value of 0.05 or less will be considered statistically significant.

    Time frame: Up to 12 weeks after completion of study treatment

Other outcomes

  1. Biomarkers of response and resistance to anti-inducible T-cell co-stimulator (ICOS) monoclonal antibody MEDI-570

    Predictors of clinical outcomes will be investigated using logistic regression, Cox proportional hazards regression and/or generalized estimating equations as appropriate. Potential predictors include clinical predictors and molecular correlates. Descriptive statistics and plotting of data will also be used to better understand potential relationships.

    Time frame: Up to 36 weeks
