Brief Summary:
This pilot phase 2 study evaluates the effectiveness and safety of the Rechallenge concept in patients with BRAF-positive anaplastic thyroid cancer after progression on anti-BRAF therapy Patients with BRAF-positive anaplastic thyroid cancer who were previously treated with dabrafenib and trametinib with a clinical or objective response at the start of treatment and later with tumor progression during anti-BRAF therapy and subsequent lines of chemotherapy are scheduled to undergo targeted therapy repeated administration of dabrafenib and trametinib in standard doses and evaluate the outcomes according to the primary and secondary endpoints
Detailed Description:
The aim of the study was to demonstrate the efficacy and safety of the rechallenge concept in patients with BRAF-positive anaplastic thyroid cancer after progression on anti-BRAF therapy
Scientific hypothesis rechallenge in patients with BRAF-positive anaplastic thyroid cancer after progression on anti-BRAF therapy is effective and safe
Trial design materials and methods this study is a pilot phase 2 study This study is prospective and open-label
Patients with BRAF-positive anaplastic thyroid cancer who were previously treated with dabrafenib and trametinib with a clinical or objective response at the start of treatment and later with tumor progression during anti-BRAF treatment with the transition to at least one line of chemotherapy treatment with taxane-containing regimens is mandatory followed by progression on it Patients who meet the criteria and with no initial resistance to anti-BRAF therapy are scheduled to undergo targeted therapy repeated administration of dabrafenib and trametinib in standard doses and evaluate outcomes according to primary and secondary endpoints
The control will be carried out by monitoring the initial state in dynamics Before starting investigational therapy data will be recorded for each patient in an individual registration card
Before starting investigational therapy clinical and laboratory parameters will be evaluated and computed tomography of the brain neck thoracic and abdominal cavities with intravenous contrast baseline will be performed
Mutations in the BRAF V600 gene microsatellite instability MSI and PD-L1 expression will be determined in the tumor material first of all and the following molecular genetic variants will be determined in the second place planned RET NTRK ALK ROS1
Investigational therapy includes dabrafenib 150 mg 2 times a day daily trametinib 2 mg 1 time a day daily
Duration of treatment until progression or intolerable toxicity
Follow-up period of patients
duration of the initial follow-up period taking drugs for 10 days followed by an assessment of the effect using tumor imaging methods
follow-up during active treatment in the framework of the study with tumor reduction after day 10 - continuation of targeted therapy until progression or intolerable toxicity
patient survival monitoring - documenting subsequent lines of antitumor treatment before the patients death or loss of contact with him
patient safety monitoring is the period of research therapy 30 and 90 days from the date of the final dose provided there is no next line of antitumor treatment during the next line safety monitoring is discontinued
Assessment of the response to treatment assessment of clinical and laboratory parameters computed tomography of the brain neck chest and abdominal cavity with intravenous contrast will be carried out after 10 days then - according to the decision of the research team Based on the results of the control study the response to treatment will be evaluated according to the RECIST 11 criteria Patients who meet the criteria for progression will be excluded from the study
When converting a tumor to resectability and planning surgical treatment it is recommended to suspend taking the drug trametinib 5 days before surgery and resume taking it 3-5 days after There is no correlation between dabrafenib and complications associated with surgical treatment and no interruptions in treatment are required
