Combination Targeted Therapy With Pembrolizumab and Lenvatinib in Progressive, Radioiodine-Refractory Differentiated Thyroid Cancers: A Phase II Study

This phase II trial studies how well pembrolizumab and lenvatinib work in treating patients
with differentiated thyroid cancer that has spread to other places in the body or has come
back and cannot be removed by surgery. Monoclonal antibodies, such as pembrolizumab, may
stimulate the immune system to attack the cancer, and kinase inhibitors, such as lenvatinib,
may interfere with the ability of tumor cells to grow and spread.

PRIMARY OBJECTIVES:

I. To investigate the clinical efficacy, as indicated by the rate of complete response (CR)
per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, of combination therapy with
pembrolizumab and lenvatinib in lenvatinib-naive patients with progressive
radioiodine-refractory differentiated thyroid cancers (DTC). (Cohort 1) II. To determine the
overall response rate (ORR) by the addition of pembrolizumab to patients with
radioiodine-refractory DTC who have progressive disease on lenvatinib alone. (Cohort 2)

SECONDARY OBJECTIVES:

I. To determine the safety profile and toxicity of combination therapy with pembrolizumab and
lenvatinib in patients with progressive DTC. (Cohort 1 and cohort 2) II. To determine
progression-free survival (PFS) and overall survival (OS). (Cohort 1 and cohort 2)

TERTIARY OBJECTIVES:

I. To correlate tumor response (RECIST 1.1) with pretreatment frequency of CD8+ T cells in
the primary and/or metastatic tumor. (Cohort 1 and cohort 2) II. To correlate tumor response
(RECIST 1.1) with pretreatment PD-L1 and PD-L2 levels in the primary and/or metastatic tumor.
(Cohort 1 and cohort 2) III. To correlate tumor response (RECIST 1.1) with pretreatment
frequency of lymphocytes expressing CD3, CD4, PD-1, FoxP3, or CD20, and of CD163+
macrophages. (Cohort 1 and cohort 2) IV. To correlate tumor response (RECIST 1.1) with the
phenotype and frequency of key leukocyte subsets (i.e., PD-1+ T cells, regulatory T cells
[Tregs], myeloid subsets) in the peripheral blood before, at 6 and 18 weeks on therapy, and
at 54 weeks (study completion), progressive disease (PD), or study withdrawal. (Cohort 1) V.
To correlate tumor response (RECIST 1.1) with PD-1+ T cell functional capacity. (Cohort 1)
VI. To correlate tumor response (RECIST 1.1) with serum anti-thyroglobulin antibody levels
assessed before, and at 18 weeks on therapy. (Cohort 1 and 2) VII. To correlate tumor
response (RECIST 1.1) with tumor mutation status. (Cohort 1) VIII. To broadly investigate
mechanisms of response and resistance to combination therapy, gene expression profiles will
be generated from frozen biopsies for analysis by ribonucleic acid-sequencing (RNA-Seq).
(Cohort 1)

OUTLINE:

Patients receive lenvatinib orally (PO) once daily (QD) on days 1-21 and pembrolizumab

courses in the absence of disease progression or unacceptable toxicity. Patients may continue
treatment for up to 35 courses.
