Phase I/II Trial of Cediranib Alone or Cediranib and Lenalidomide in Iodine 131-Refractory Differentiated Thyroid Cancer
PRIMARY OBJECTIVES:
I. Determine the maximum tolerated dose (MTD) of cediranib (cediranib maleate) plus
lenalidomide. (Phase I) II. Determine the progression-free survival rates of single agent
cediranib in patients with iodine refractory, unresectable differentiated thyroid cancer
(DTC) who have evidence of disease progression within 12 months of study enrollment. (Phase
II) III. Determine the progression-free survival rates of cediranib in combination with
lenalidomide in patients with iodine refractory, unresectable DTC who have evidence of
disease progression within 12 months of study enrollment. (Phase II) IV. Compare the
progression-free survival curves of single agent cediranib to combination therapy with
cediranib with lenalidomide. (Phase II)
SECONDARY OBJECTIVES:
I. Determine the response rate of cediranib in combination with lenalidomide in patients
with iodine refractory, unresectable DTC who have evidence of disease progression within 12
months of study enrollment. (Phase I) II. Determine the toxicity, duration of response,
progression free survival, and overall survival in patients with DTC treated with cediranib
plus lenalidomide. (Phase I) III. Determine response rates and duration of response, early
tumor size changes, the toxicity, and overall survival in patients with DTC treated with
cediranib or cediranib plus lenalidomide. (Phase II) IV. Determine whether the presence of
v-raf murine sarcoma viral oncogene homolog B1 (B-RAF) or V-Ki-ras2 Kirsten rat sarcoma
(K-RAS) mutations in patients with DTC predict response to cediranib or cediranib plus
lenalidomide. (Phase II)
OUTLINE: This is a phase I, dose-escalation study followed by a phase II study.
Phase I: Patients receive cediranib maleate orally (PO) once daily (QD) on days 1-28 and
lenalidomide PO QD on days 1-21 or 1-28. Courses repeat every 4 weeks in the absence of
disease progression or unacceptable toxicity.
Phase II: Patients are randomized to 1 of 2 treatment arms.
ARM A: Patients receive cediranib maleate PO QD on days 1-28. Courses repeat every 4 weeks
in the absence of disease progression or unacceptable toxicity.
ARM B: Patients receive cediranib maleate PO and lenalidomide PO as in Phase I.
After completion of study treatment, patients are followed up periodically.
