NCT ID NCT05733013

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study is gathering information from 100 adults with a type of thyroid cancer that no longer responds to standard radioactive iodine treatment. Doctors are using special medications called redifferentiating agents to try to make the cancer respond again. The goal is to track how well these drugs work and what side effects occur when they are used in regular medical practice, not just in a research setting.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients ≥ 18 years old at time of consent Inclusion Criteria: * Patients diagnosed with RAI refractory thyroid cancer or unlikely to respond to RAI. * Patients who will receive redifferentiation agents prior to planned diagnostic and/or therapeutic use of radioactive iodine as part of routine clinical care. * Patients who have never received redifferentiation agents outside of a clinical trial or have received redifferentiation agents in the context of a clinical trial will be enrolled after the clinical team has decided to proceed with a redifferentiation agent as part of routine clinical care prior to diagnostic and/or therapeutic radioactive iodine administration. * Patients previously treated with redifferentiation agents as part of clinical care prior to diagnostic and/or therapeutic radioactive iodine administration who are willing to provide retrospectively collected data surrounding the time of the previous treatment and will provide prospective data from the time of consent. Exclusion Criteria: * RAI refractory thyroid cancer patients that will receive redifferentiation agents prior to diagnostic and/or therapeutic use of radioactive iodine as part of a prospective clinical trial.
