CABOTHYROID is a prospective, exploratory, biomarker-focused, phase II, single-arm, non-randomized, non-blinded, investigator-initiated study of cabozantinib in patients with previously treated advanced radioactive-iodine refractory
The trial will enroll competitively up to 41 subjects; male and female, ≥ 18 years, with ECOG PS 0-1 patients with advanced radioactive-iodine refractory differentiated thyroid cancer (DTC) who progressed to previous Tyrosine kinase inhibitors (TKIs), including but not limited to lenvatinib or sunitinib. Patients will have not received previously cabozantinib, selective small-molecule BRAF kinase inhibitors, immune checkpoint inhibitor therapy, or systemic chemotherapy regimens.
The design includes a screening phase in which patient eligibility is addressed, a treatment phase, and a follow-up phase.
Study treatment will begin as soon as possible after signing the informed consent and inclusion will be completed.
All patients will receive cabozantinib at a fixed dose of 60 mg once a day (QD). Patients will continue study treatment until PD (either clinical or radiological), or until unacceptable toxicity, the need for another systemic anticancer treatment, or other reasons for treatment discontinuation.
All patients will undergo periodic tumor assessments by CT or MRI scan every 12 weeks ± 14 days (3 months), and blood monitoring of tumor markers (i.e. thyroglobulin if applicable) every 12 weeks ± 3 days (2 months) from the start of study treatment until progression or patient withdrawal. Further CT/MRI scans could be performed upon suspicion of disease progression according to standard clinical practice and physician criteria. Safety will be assessed at every visit through continuous monitoring of signs and symptoms and periodic laboratory analysis.
The study includes the collection of two blood samples (baseline and after PD; 40 mL at each timepoint) for the determination of cf CHIP-seq (Chromatin immunoprecipitation-sequencing) and patient reported outcomes.

Note: If a single shows a QTcF with an absolute value > 500 ms, two additional ECGs at intervals of approximately 3 min must be performed within 30 min after the initial ECG, and the average of these 3 consecutive results for QTcF will be used to determine eligibility.
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).
Your pathology report is the document that shows this.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.
The standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.
“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.
A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.
“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.
The US National Cancer Institute’s scale of how severe an adverse event is — any unwanted medical event during a study, such as a symptom, an illness or an abnormal test result, whether or not a treatment caused it. Whether it did is judged separately.
“Side effects of earlier treatment resolved to grade 1 or less” means they have settled to mild or gone.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.
It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).
PD-1, PD-L1 and CTLA-4 are proteins that act as brakes on the immune system. Checkpoint inhibitors, such as pembrolizumab or nivolumab, block them so the immune system can attack a cancer.
PD-L1 can also be measured in a tumour sample. Some scores count stained tumour cells only (TPS); others also count certain immune cells (CPS). The study names the score and the minimum it uses.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).
Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.
Stroke symptoms need emergency care at once, even if they go away.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
A score of how well the liver works in people with liver disease such as cirrhosis: class A is mild, B moderate and C severe.
On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.
The study may name a correction formula and a limit in milliseconds, often around 450–480.
A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Patients with advanced radioactive-iodine refractory DTC who progressed to previous TKIs (including but not limited to lenvatinib or sunitinib). Patients will have not received previously cabozantinib, selective small-molecule BRAF kinase inhibitors, immune checkpoint inhibitor therapy, or systemic chemotherapy regimens.
Drug: Cabozantinib
* All enrolled patients will receive cabozantinib at a fixed dose of 60 mg once a day (QD). Patients will continue study treatment until PD (either clinical or radiological), or until unacceptable toxicity, the need for another systemic anticancer treatment, or other reasons for treatment discontinuation. * Patients will take the tablet(s) once daily at bed time except for Week 1 Day 1: the first dose of study treatment will be administered in the clinic so that each patient can be observed for initial tolerability. Subsequent doses will be self-administered at home. The tablets should be swallowed whole and not crushed and administered fasting for at least 2 hours before through 1 hour after. If a patient misses a dose, the missed dose should not be taken if it is less than 12 hours before the next dose.
Gene expression of molecular biomarkers characteristics of the pathology
Gene expression levels in the sample will be reported as media and interquartile range for each one of the biomarkers included in the determination. Determination of the expression of the molecular markers will perform applied chromatin immunoprecipitation of cell-free nucleosomes carrying active chromatin modifications followed by sequencing chromatin immunoprecipitation (cfChIP-seq) in blood samples. A blood sample of each patient will be collected for cfChIP-seq analysis in the baseline, before any dose of study treatment (week0)
Time frame: Time point: At baseline, before any dose of study treatment
Gene expression of molecular biomarkers characteristics of the pathology
Gene expression levels in the sample will be reported as media and interquartile range for each one of the biomarkers included in the determination. Determination of the expression of the molecular markers will perform applied chromatin immunoprecipitation of cell-free nucleosomes carrying active chromatin modifications followed by sequencing chromatin immunoprecipitation (cfChIP-seq) in blood samples. A blood sample of each patient will be collected and cfChIP-seq test will be performed as soon as the patient progresses according to RECIST 1.1 guidelines
Time frame: Time point: Throughout the study period, approximately 2 years per patient
Objective response rate (ORR)
Objective response rate (ORR), primary endpoint for efficacy: Assessed by the investigator through imaging follow-up (CT scan/MRI) using RECIST 1.1. This will be considered as the percentage/proportion of patients with confirmed complete response (CR) or partial response (PR) as their overall best response throughout the study period. Objective responses will be assessed locally by the investigator according to RECIST, version 1.1, and indicating the change in size of tumors as compared with baseline, at the first dose of study treatment.
Time frame: Throughout the study period, approximately 2 years per patient
Disease control rate (DCR)
Percentage/proportion of patients with complete response (CR) or partial response (PR), according to ORR definition for the trial, or maintained stable disease (SD) as their overall best response, assessed by imaging follow-up (CT scan/MRI) and RECIST 1.1 criteria. Stable disease should be maintained for at least 4 months to be considered as a Chemical, Biological, or Radiological (CBR) event
Time frame: Throughout the study period, approximately 2 years per patient
Duration of response (DoR)
DoR is defined as the time from first confirmed response (CR or PR), according to ORR definition for the trial, to the date of the documented PD as determined using RECIST 1.1 criteria or death due to any cause, whichever occurs first. Those patients with response and without PD or death event will be censored on the date of their last tumor assessment.
Time frame: Throughout the study period, approximately 2 years per patient
Progression-free survival (PFS)
PFS is defined as time from first dosing date to the date of confirmed PD according to RECIST 1.1. Patients alive and free of events at the date of the analysis will be censored at their last known tumor assessment. Patients who start a new treatment line without progression will be censored on the date of first dose of the subsequent anticancer treatment.
Time frame: Throughout the study period, approximately 2 years per patient
Overall survival (OS)
Defined as the time elapsed from the first dose of study treatment until death from any cause. We will assess the median OS, estimated by Kaplan-Meier. Patients alive and free of events at the date of the analysis will be censored at their last known contact. Survival will be assessed by recording patient status at each visit according to Table 1. Long term follow up to be performed at least every 6 months.
Time frame: Throughout the study period, approximately 2 years per patient
Frequency of Adverse events (AEs) leading to treatment discontinuation.
Percentage of patients experiencing an adverse event leading to discontinuation of treatment
Time frame: Throughout the study period, approximately 2 years per patient
Health-related quality of life (HRQoL), assessed through the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) version 3.
The EORTC QLQ-C30 questionnaire is a specific questionnaire validated for cancer that is composed of 30 questions or items. The questionnaire is structured in 5 functional scales (physical functioning, daily activities, emotional functioning, cognitive functioning and social functioning), 3 symptom scales (fatigue, pain and nausea, vomiting), 1 global health status scale, and 6 independent items (dyspnea, insomnia, anorexia, constipation, diarrhea and economic impact). Values between 1 and 4 (1: not at all, 2: a little, 3: quite, 4: a lot) are assigned according to the patient's responses to the item, only in items 29 and 30 are they evaluated with a score of 1 to 7 (1: dreadful, 7: excellent). The scores obtained are standardized and a score between 0 and 100 is obtained, which determines the level of impact of the cancer on the patient on each of the scales. A higher score indicating a better HRQoL.
Time frame: Throughout the study period, approximately 2 years per patient
