RAD001 for Patients With Radioiodine Refractory Thyroid Cancer

A Phase II Trial Using RAD001 for Patients With Radioiodine Refractory Thyroid Cancer

Since thyroid cancer becomes refractory to radioactive iodine, treatment options are very limited. Tyrosine kinase inhibitors such as sorafenib have recently shown promise. This trial seeks to expand treatment options for this disease with a new, oral drug called RAD001. It is an inhibitor of the mTOR pathway and has shown activity in neuroendocrine cancers of the gastrointestinal tract and has been approved for the treatment of metastatic renal cell cancer.

Study Overview

• Status: Completed
• Conditions: Thyroid Cancer
• Intervention / Treatment: Drug: RAD001

Detailed Description

• RAD001 will be taken once a day in the morning starting on Day 1 and continue until the participant is no longer participating in the study treatment.
• A history and physical exam will be performed the first day of the study and then once a month. Blood tests including coagulation studies, and thyroid studies will be performed monthly. A urine sample will need to be provided on the first day of treatment and then every 2 months. Imaging consisting of a CT or MRI of the neck, chest and abdomen will be done every 8 weeks after starting RAD001.
• Participants will remain on this research study for up to 24 months. However, if the participants doctor feels that they are benefiting from the study drug and they do not have severe side effects, they may be given the option to continue taking RAD001.

• Study Type: Interventional

Description

Inclusion Criteria:

• Histologically confirmed locally advanced or metastatic thyroid cancer, excluding thyroid lymphomas not amenable to or refractory to surgical resection, external beam radiotherapy, radioiodine or other local therapies.
• Prior therapy with chemotherapy and targeted therapies except for mTor inhibitors is allowed.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Median Progression Free Survival	Progression free survival (PFS) is defined as the time from start of treatment to disease progression or death from any cause as estimated by Kaplan Meier methods. Progression is measured using RECIST 1.1 criteria, defined as at least a 20% increase in size in target lesion and/or unequivocal progression of non-target lesions and/or appearance of new lesions. Patients who have not progressed and are alive are censored at the date the patient is known to be progression-free.	Every 2 months for first 24 months, then every 3 months from >24 to 60 months; up to 48 months.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Objective Response Rate	The objective response rate is the proportion of participants achieving complete response (CR) or partial response (PR) on treatment based on Response Evaluation Criteria In Solid Tumors Criteria (RECIST 1.1) criteria. PR or better is achieved if the following are true: Target Lesions: -At least a 30% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. Non-target Lesions: No progression. No appearance new lesions or unequivocal progression of existing non-target lesions. Unequivocal progression should not normally trump target lesion status. It must be representative of overall disease status change, not a single lesion increase. Bone Lesions: ->50% increase in lesions. -No new lesions.	Every 2 months for first 24 months, then every 3 months from >24 to 60 months; up to 48 months.
Median Overall Survival	Overall Survival (OS) is defined as the time from randomization (or registration) to death due to any cause, or censored at date last known alive.	Every 2 months for first 24 months, then every 3 months from >24 to 60 months; up to 5 years post study registration.
Mean Change in Quality of Life [Medullary Thyroid Cancer Population Only]	The M. D. Anderson Symptom Inventory (MDASI) questionnaire was used to assess quality of life. Questions 1 to 19 were scored. Each of the 19 questions have a response range of 0 - 10, where 0 represents "not present" and 10 represents "as bad as you can imagine". The 19 responses are averaged together to create a mean score, with a lower score indicating a better quality of life. All questionnaire mean scores at each timepoint are averaged together to give a mean score at that timepoint (baseline and week 8) The mean change in quality of life is calculated by subtracting the baseline mean score from the week 8 mean score.	Measured at baseline and then again at cycle 8 (8 months).
