About this study

Official title: Observational Study on Gender-based Impact on Safety and Efficacy of Lenvatinib in Patients With Radioiodine Refractory Differentiated Thyroid Cancer

Lenvatinib is approved for the treatment of radioiodine refractory differentiated thyroid cancer. Despite gender can play a crucial role un in safety and efficacy of oncological product, little is know on gender difference in lenvatinb effacacy and safety in the context of radioiodine refractory differentiated thyroid cancer.

The primary objective of the study is to assess safety and toxicity profile in male and female patients in terms of dose reduction. The secondary objectives are to assess sex and gender difference in: the number and the incidence of adverse events; response rate according to RECIST criteria 1.1; progression free survival, overall survival and duration of response.

Read the detailed description

Lenvatinib is an orally available potent inhibitor of the split-kinase family of transmembrane growth factor receptors including Flt-1/VEGFR-1 and KDR/VEGFR. Lenvatinib has been investigated in hepatocellular carcinoma and in RAI-resistant thyroid cancer (Phase III trials) and in other malignancies, showing high rates of activity. In RAI-resistant thyroid cancer, lenvatinib showed a remarkable response rate over placebo (65% vs 2), combined with a prolonged progression free survival (18.3 vs 3.6 months). It has been approved for the treatment of locally recurrent or metastatic, progressive RAI resistance-DTC in the United States, Europe, and Japan, based on the results from SELECT trial. Moreover, lenvatinib demonstrated a meaningful clinical activity (response rate 64.8% in treatment arm vs 1.5% in placebo arm, p<0.001;) significantly reducing the tumour burden, with a median maximum percentage change in tumour size of -42.9%. Response was mostly pronounced at the first assessment (median -24.7% at 8 weeks after randomization) but it has been observed even in the following months (-1.3% per month). Recently, the efficacy of lenvatinib was confirmed in specific patient population, such as elderly. Although the efficacy is remarkable toxic effects are considerable and not all patients have the same risk to benefit ratio from lenvatinib treatment. Results derived from controlled clinical trials are rarely replicable in the real-life because these trials are usually conducted in selected populations, in a highly controlled setting, optimized to show the effect of the drug.

In this context growing evidences are showing gender associated functions playing a role in cancer incidence, progression and response to therapy; gender disparities in toxicities and effectiveness of certain drugs used in the treatment of the most common cancer is already well known.The aim of the present study is to evaluate the safety and efficacy profile of Lenvatinib based on gender in patients with refractory iodine DTC.

    Difference in lenvatinib dose reduction between male and female patients

    Measured: 1 year

Secondary outcomes (3)
  1. Gender difference in lenvatinib side effects incidence

    Measured: 1 year

  2. Gender difference in lenvatinib response rate

    Difference in lenvatinib response rate (CR+PR) according to RECIST response evaluation criteria 1.1 in male and female patients.

    Measured: 1 year

  3. Gender difference progression free survival and overall survival of patients treated with lenvatinib

    Difference in progression free survival and overall survival of patients treated with lenvatinib in male and female patients.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Differentiated Thyroid Cancer and Gender, run by Regina Elena Cancer Institute at 1 site in Italy.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Gender difference in Safety profile of lenvatinib treatment (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Aug 2026.
