A Phase I and Randomized Phase II Study of KW-0761 (Mogamulizumab) and MK-3475 (Pembrolizumab) in Relapsed and Refractory Lymphomas

This randomized phase I/II trial studies the best dose and side effects of mogamulizumab in
combination with pembrolizumab and to see how well they work in treating patients with
lymphomas that have come back after a period of improvement or does not respond to treatment.
Immunotherapy with monoclonal antibodies, such as mogamulizumab and pembrolizumab, may help
the body's immune system attack the cancer, and may interfere with the ability of tumor cells
to grow and spread.

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose (MTD) or recommended phase 2 dose (RP2D) of
mogamulizumab when administered in combination with pembrolizumab in patients with relapsed,
refractory lymphomas. (Phase I) II. To assess the safety and tolerability of mogamulizumab
when administered in combination with pembrolizumab in patients with relapsed, refractory
lymphomas. (Phase I) III. To assess the progression-free survival of mogamulizumab when
administered in combination with pembrolizumab compared to pembrolizumab alone in patients
with relapsed and refractory diffuse large B-cell lymphomas. (Phase II)

SECONDARY OBJECTIVES:

I. To observe and record anti-tumor activity. (Phase I) II. To assess the overall response
rate, complete response rate, partial response rate, duration of response of mogamulizumab
and pembrolizumab compared to pembrolizumab alone in patients with relapsed and refractory
diffuse large B-cell lymphomas. (Phase II)

EXPLORATORY OBJECTIVES:

I. To determine whether the progression-free survival of mogamulizumab and pembrolizumab when
administered to patients with relapsed and refractory diffuse large B-cell lymphomas differs
based on the presence or absence of mutations in B2M or CD58 or amplifications in PD-L1.

II. To determine whether the progression-free survival of mogamulizumab and pembrolizumab
when administered to patients with relapsed and refractory diffuse large B-cell lymphomas
differs based on changes in CD8 T-cell, natural killer (NK) cell, and FoxP3+ regulatory T
cell (Treg) prevalence in response to therapy as measured by immunohistochemistry.

III. To determine whether mogamulizumab and pembrolizumab alters the prevalence of peripheral
blood CCR4+/FoxP3+ regulatory T-cells as well as effector CD4 and CD8 T-cells by
multi-parametric flow cytometry.

OUTLINE: This is a phase I, dose-escalation study of mogamulizumab followed by a phase II
study. Patients are randomized to 1 of 2 arms.

ARM I: Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1 and
mogamulizumab IV over 60 minutes on days 1, 8 and 15 of course 1, then day 1 of subsequent
courses.

ARM II: Patients receive pembrolizumab IV over 30 minutes on day 1.

In both arms, courses repeat every 21 days for up to 2 years in the absence of disease
progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 4 weeks.

Inclusion Criteria:

refractory lymphoma for which standard curative or palliative measures do not exist or
are no longer effective; this includes non-Hodgkin and Hodgkin lymphomas

previously received or been deemed ineligible for autologous stem cell transplantation

- Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60%)

involvement with lymphoma, the absolute neutrophil count must be >= 1,000/mcL)

- Platelets >= 75,000/mcL (if thrombocytopenia is related to bone marrow involvement
with lymphoma, the platelet count must be >= 50,000/mcL)

the hemoglobin must be >= 8 g/dL)

institutional upper limit of normal
