Combining mirdametinib and vorinostat for treating specific nerve tumors in NF1 patients

Official title: A Window of Opportunity Trial of Mirdametinib Plus Vorinostat for NF1 Associated, H3K27 Trimethylation Deficient Malignant Peripheral Nerve Sheath Tumor [MPNST]

Run by University of Minnesota · NCT06693284 · Data updated 2026-11-12

This study is testing a new combination of two medications to see if they can help patients with a specific type of nerve tumor related to Neurofibromatosis type 1 before starting regular treatments.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals aged 12 years or older with NF1 and histone H3K27 trimethylation deficient MPNST.

Probably not a fit

Patients without NF1 or those with other types of tumors not meeting the histone deficiency criteria may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This trial investigates the effectiveness of a short course of mirdametinib and vorinostat in patients with newly diagnosed malignant peripheral nerve sheath tumors (MPNSTs) associated with Neurofibromatosis type 1 (NF1) and specific histone deficiencies. The study aims to enroll 4 to 8 patients aged 12 years or older who meet the biomarker criteria. Participants will undergo imaging and a biopsy before receiving the treatment, followed by a repeat MRI to assess the tumor's response. This early-phase trial serves as a 'window of opportunity' before standard treatment options are initiated.

Why it matters

Potential benefit: If successful, this approach could provide a new treatment option for patients with aggressive nerve tumors, potentially improving outcomes.

How similar studies have gone: While this specific combination is novel, similar approaches targeting tumor biology in NF1-related tumors have shown promise in other studies.
