Active clinical trials for "Neurofibroma"

A global study to demonstrate the effectiveness of selumetinib in participants with NF1 who have symptomatic, inoperable plexiform neurofibromas.

This is a phase 2, open-label, interventional clinical trial that will study the response rate of pediatric glioma and plexiform neurofibroma (PN) to oral administration of trametinib. Patients meeting all inclusion criteria for a given study group will receive the study medication at a daily dose of 0.025 mg/kg up to a total of 18 cycles, in 28-day cycles. A total of 150 patients will be recruited as part of this clinical study. Patients aged between 1 month (corrected age) and 25 years old will be eligible, in order to include a maximum of patients affected by low-grade glioma (LGG) and PN. This study includes four groups: patients with neurofibromatosis type 1 (NF1) and LGG, NF1 patients with PN, patients with LGG with a B-Raf Serine/Threonine-protein Kinase/Proto-oncogene Encoding B-Raf (BRAF) fusion and patients with glioma of any grade with activation of the Mitogen-activated Protein Kinase/Extracellular Signal-regulated Kinases (MAPK/ERK) pathway. All patients except patients with PN must have failed at least one line of treatment. The study will also explore the molecular mechanisms behind tumor development, progression and resistance to treatment. Furthermore, this study will also explore important aspects for patients with brain tumors by including assessment of quality of life and neuropsychological evaluation.

This is a phase II open label study that will evaluate children ≥ 1 year of age and adults with neurofibromatosis type 1 (NF1) and plexiform neurofibromas treated with the MEK inhibitor, binimetinib. The primary objective is to determine if there is an adequate level of disease responsiveness to binimetinib in children and adults with NF1 and inoperable plexiform neurofibromas. The objective response to binimetinib is defined as ≥ 20% decrease in tumor volume reduction by 12 courses.

This study evaluates mirdametinib (PD-0325901) in the treatment of symptomatic inoperable neurofibromatosis type-1 (NF1)-associated plexiform neurofibromas (PNs). All participants will receive mirdametinib (PD-0325901). Eligible participants may continue in a long-term follow-up phase.

Children with neurofibromatosis type 1 (NF1) commonly suffer from the effects of cognitive, behavioral, and motor impairments. At present there is no specific treatment for this NF1 complication. However, data from rodent models of NF1 along with uncontrolled clinical observations in children with NF1 suggest that the anti-oxidant, glutamate modulating compound N-Acetyl Cysteine (NAC) may reduce these impairments. Of particular interest is a murine study analyzing the central nervous system manifestations of NF1 at our institution. That study revealed a role for myelin-forming oligodendrocytes in the control of nitric oxide synthases (NOS) and their product, nitric oxide, in maintenance of brain structure and function, including regulation of behavior and motor control. Treating these mice with NAC corrected cellular and behavioral abnormalities. N-Acetyl Cysteine is available over the counter and has been used by thousands of individuals; moreover, it has shown some promise in clinical trials for psychiatric disorders. In order to better understand treatment mechanisms, and possibly predict long-term outcomes, the investigators propose concurrently to explore Specific Aim 1 (1.1, 1.2, and 1.3) exploratory potential disease biomarkers as outlined below. The primary outcome of this study is motor function rated with the Physical and Neurological Examination for Subtle Signs (PANESS), a validated scale that consistently demonstrates significant impairments in children with Attention Deficit Hyperactivity Disorder (ADHD), and which our preliminary data suggest may demonstrate more extreme problems in children with NF1. The first exploratory biomarker is motor system inhibitory physiology, measured using Transcranial Magnetic Stimulation (TMS). Preliminary measures in our NF1 population also show abnormalities similar to established findings in ADHD. The second exploratory biomarker is metabolomics profiling for the biomarker of oligodendrocyte dysfunction in NF1 participants: autotaxin. Preliminary data in our NF1 population showed specific signal abnormalities in the NF1 population compared to healthy controls. Therefore, the investigators propose to perform a double-blind placebo controlled, prospective, Phase IIa study to explore safety, tolerability, and efficacy of NAC on learning and motor behavior in children with NF1 aged 8 through 16 years old.

This study in adolescent participants with NF1 who have inoperable PN is designed to evaluate the effect of a low fat meal on steady state selumetinib exposure; to assess the effect on GI tolerability when selumetinib is dosed under fed and fasted conditions; and potentially, to confirm an appropriate dosing recommendation of selumetinib with a low fat meal that maintains efficacy with acceptable safety. These results may support labelling statements with regard to posology and food.

The purpose of the study is to determine if RAD001 treatment will shrink or slow the growth of the vestibular schwannoma(s) in Neurofibromatosis 2 (NF2) patients. Secondary objectives include determining if RAD001 treatment will improve hearing ability in NF2 patients. RAD001 is an oral drug that is approved by Food and Drug Administration (FDA) for other types of tumors, it is not approved by the FDA for treatment of NF2 related tumors.

Bevacizumab can be an effective treatment for individuals with NF2 and improve different nerve functions (like hearing, tinnitus or balance problems) and the quality of life of NF2 patients. However, bevacizumab is not effective in all patients or all tumors, at the cost of moderate toxicity and considerable financial burden. Therefore, this observational study will validate an imaging biomarker method to predict bevacizumab efficacy in order to avoid adverse effects and high costs in non-responders to bevacizumab treatment. Patients will undergo standard-of-care treatment with the sole addition of a pre-treatment 89Zr-Bevacizumab PET/CT-scan. Per standard-of-care bevacizumab therapy is administered every three weeks for six months. To monitor treatment effect, follow-up is performed at 3-month intervals.

This is a single arm pilot trial of a novel whole-body Magnetic Resonance Imaging paired with artificial intelligence intervention, to evaluate feasibility defined as scan-rescan reliability, and to estimate the positive predictive value of changes in Magnetic Resonance Imaging scans from baseline to 12-month visit using an Artificial Intelligence algorithm, among 15 pediatric patients with neurofibromatosis type 1 at Cedars-Sinai Medical Center.

This study is a Phase I clinical trial to evaluate the tolerability and pharmacokinetics of TQ-B3234 capsules in Chinese subjects associated with neurofibromatosis type I (neurofibroma and peripheral malignant neurilemmoma). Two study phases were designed, including (1) dose escalation and (2) cohort expansion. The purpose of this study was to evaluate the tolerance, pharmacokinetic characteristics, efficacy and safety of TQ-B3234 capsule, and to explore the therapeutic biomarkers related to this product.
