About this study

Anaplastic thyroid cancer (ATC) is an almost invariable lethal cancer in humans.

Most patients present with a rapid progressive mass in the neck with progressive complaints like dyspnoea, dysphagia or pain. The risk of suffocation is the main reason for rapid surgical intervention, but we know from literature that an oncological resection with clear margins is seldomly achieved. Some patients deteriorate that fast after surgery that radiation therapy and/or chemotherapy is not feasible anymore. Patients with BRAF-mutated ATC already have shown to benefit from targeted BRAF/MEK inhibition. This study aims to increase the number of patients that undergo a successful R0 tumor resection after neo-adjuvant BRAF/MEK inhibitor treatment.

Read the detailed description

Unmet need ATC is a very serious condition and is, apart from a few exclusive cases, always lethal. Many patients suffer uncontrollable loco-regional disease with even so uncontrollable complaints of airway obstruction, oesophagus obstruction, pain and neck movement impairment. One of the only shown beneficial treatment is complete surgical resection with clear surgical margins combined with radiotherapy and systemic treatment. However, in less than 10-15% of the patients the pathologist reports clear surgical margins. Thereby it is noticeable that surgery often results in serious morbidity, due to an esophagectomy, laryngectomy or trachea resection all accompanied by an extensive reconstruction. All of these come with serious morbidity and seldomly lead to clear margins and better outcome.

Proposed solution A single center, phase II study for the evaluation of safety and efficacy of neo-adjuvant and adjuvant dabrafenib/trametinib treatment in BRAF mutated ATC patients. By introducing neo-adjuvant treatment the hypothesis is that better selection is done for patients who are eligible for complete surgery and that surgery results more often in clear surgical margins after neo-adjuvant treatment. Second benefit of treating patients with combined loco-regional and systemic agents before surgery is that micro/macrometastases (being there in at least 30% of the patients at diagnosis) are already being treated directly after diagnosis. Lastly, adjuvant treatment with dabrafenib/trametinib will hopefully result in reduction of local and distant recurrences after surgery.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groupRoleWhat they receive
neo-adjuvant and adjuvant braf/mek-inhibitionExperimentalParticipants will undergo neo-adjuvant treatment with dabrafenib/trametinib. After 6 weeks of BRAF/MEK inhibitors, participants will undergo an evaluation of resectability. If the tumor is resectable, patients undergo tumor resection. If not resectable, neo-adjuvant treatment continues for another 6 weeks followed by a new evaluation. All resected patients receive adjuvant dabrafenib/trametinib up to a total treatment duration of 52 weeks. If resection is not possible, patients will continue on dabrafenib/trametinib.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing dabrafenib/trametinib in people with Anaplastic Thyroid Cancer, run by Leiden University Medical Center at 1 site in Netherlands.

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 13 inclusion and 7 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: looking for participants now, as of the sponsor's last update on 12 Oct 2023. 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 Netherlands. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact Ellen Kapiteijn, MD, PhD (0031-71-5263486, h.w.kapiteijn@lumc.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

primary endpoint of the study will be R0 resection rate (efficacy). (time frame: after 6-12 weeks braf/mek-inhibition). 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 12 Oct 2023.
