Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Prospective, interventional, open, randomized, single-center, non-commercial clinical trial to optimize treatment and dosage of trametinib in juvenile patients with histiocytosis resistant to conventional therapy and without the BRAF gene mutation or after the failure of vemurafenib treatment.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

TRAM clinical study is part of the POLHISTIO project. The POLHISTIO project is a non-commercial clinical trial aimed at optimizing the diagnosis and treatment of juvenile patients with histiocytosis. The project objectives are defined as follows: 1) to estimate the nature and frequency of mutations in patients with histiocytosis in both tumor tissues and free-circulating DNA; 2) to compare molecular test results with clinical data; 3) to evaluate the diagnostic usefulness of the status of molecular analysis (MRD) as a prognostic factor compared with other recognized factors; 4) in the case of failure of conventional therapy - to modify treatment and to apply targeted treatment, based on molecular status of gene mutation. The project is intended to include patients from all over Poland.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Lack of mutations in the BRAF gene in tumor tissues and/or circulating tumor DNA (ctDNA) at any stage of treatment or follow-up, or failure of Vemurafenib treatment in BRAF positive patients.
2. Failure of the treatment (at least one of below needs to apply in order for this requirement to be satisfied):

1. Progression on the I and/or II line treatment, including at least one risk organ; prior treatment should include a minimum of 6 weeks of weekly Vinblastine with a minimum of 28 days prednisolone or minimum 2 cycles of Cytosine Arabinoside in 4-day cycles and/or Cladribine in 5-day cycles as a 2nd line treatment, minimum 2 cycles, or other second-line treatment or
2. Disease reactivation after an initial response to treatment with Vimblastine and prednisolone as the first line and/or no response to second line treatment using one of two drugs: Cytosine Arabinoside in 4- day cycles and/or Cladribine in 5-day cycles, minimum 2 cycles, or other I/ II line treatment or occurrence of involvement of at least one risk organ or

d. Progression during Vemurafenib therapy, or e. Reactivation of disease after Vemurafenib therapy has been completed, or f. The appearance of signs of neurodegenerative disorder (ND) in MRI of the central nervous system (CNS).
3. Signing of informed consent for trial participation (including for Trametinib treatment) according with current legal regulations.
4. Consent to the use of effective contraception throughout the Trametinib administration period and a minimum of 1 year after discontinuation in patients at puberty and sexual maturity.
5. Participation in HISTIOGEN trial.

2. Pregnancy and breastfeeding .
3. Hypersensitivity to the study drug or any of its ingredients.
4. Iritis, uveitis, obstruction of the retinal veins.
5. Simultaneous treatment with other drugs which might interact with Trametinib.
6. Persistent toxicity related to prior therapy, making it impossible to treat with Trametinib.
7. Diagnosis of other malignancies before study inclusion.
8. Other acute or persistent disorders, behaviors or abnormal laboratory test results, which might increase the risk related to the participation in this clinical trial or to taking the study drug, or which might influence the interpretation of the study results, or which, in the investigator's opinion, disqualify a patient from participating in the trial.
