A Phase I Trial of MEDI-570 in Patients With Relapsed/Refractory Peripheral T-Cell Lymphoma (PTCL) Follicular Variant and Angioimmunoblastic T-Cell Lymphoma (AITL)

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 angioimmunblastic T-cell lymphoma that has returned after a period of improvement (relapsed) or has not responded to previous treatment (refractory). Monoclonal antibodies, such as anti-ICOS monoclonal antibody MEDI-570, may block cancer growth in different ways by targeting certain cells.


     I. To determine the safety, maximum tolerated dose and recommended phase II dose (RP2D) of MEDI-570 (anti-ICOS monoclonal antibody 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).


     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.


     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 3 weeks for up to 12 courses 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.

         - At least 14 days from the last therapy dose or 5 half-lives (whichever is shorter), and resolution of toxicity related to the last therapy, excluding grade 2 or less peripheral neuropathy and alopecia; for radiation therapy, a minimum of 2 weeks and resolution of all acute toxicity will be required

         - Patients must have at least one measurable lesion that can be accurately measured with spiral computed tomography (CT) scan, magnetic resonance imaging (MRI) scan, or physical exam (by calipers only); (PTCL, AITL and follicular lymphoma patients will be assessed on this study using the Lugano criteria for the evaluation of lymphomas; CTCL and MF patients will be assessed using International Society for Cutaneous Lymphomas [ISCL] and European Organization for Research and Treatment of Cancer [EORTC criteria])
