Anti-ICOS Monoclonal Antibody MEDI-570 in Treating Patients With Relapsed or Refractory Peripheral T-cell Lymphoma Follicular Variant or Angioimmunoblastic T-cell Lymphoma

Brief description of study

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). 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.

Detailed Study Description


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 21 days for up to 12 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.

Clinical Study Identifier: NCT02520791
