Filter by:This study is designed to define a dosing regimen and assess the pharmacokinetics(PK) and safety of the granule formulation; the study will also include descriptive analyses of exploratory efficacy endpoints. The study will inform the benefit risk profile of the granule formulation in children aged ≥ 1 to < 7 years with NF1 related symptomatic, inoperable PN.
The overall objective is to demonstrate safety and efficacy of HIFU treatment of cutaneous neurofibromas located close to the surface of the skin in patients with the genetic disease Neurofibromatosis Type 1. The study will use a new investigational equipment that has been specially developed for dermatological therapy. The study includes 20 patients in total distributed between the two centers, each having a minimum of 8 cutaneous neurofibromas eligible for treatment. All participants are adults (over 18 years) of both sexes. The new treatment method is based on focusing intensive ultrasound just below the skin surface. This creates a very fast localized heating in small and very well-defined volumes containing neurofibroma tissue. This heating destroys or weakens the tissue, and the body's natural processes will subsequently transport affected cells away through the lymphatic and vascular systems. During the healing-process, the rejected tissue is replaced by new skin cells that are not expected to be fibrous. The treatment is intended to be carried out without breaking the skin surface, and open wounds are therefore avoided. This is an essential advantage of the method compared to all existing therapies, which are based on physical removal of tumors through an open skin surface (e.g. surgery or laser therapy). Complications with risk of pain, infection and scarring will therefore be significantly reduced with the new proposed method. The treatment is carried out by sending focused ultrasound from the handpiece of the equipment into the target area with neurofibromas. The equipment is set to send doses of approximately 150 milliseconds (0.15 seconds). The skin area and HIFU doses can be followed on the system computer screen and will be placed side-by-side with approximately 1-2 millimeter spacing. To achieve good energy transfer from handpiece to skin, ordinary ultrasound gel is used. There are no other special pre-treatments or preparations for the process. HIFU treatment is expected to be less painful than other treatments used. The treatment is quick, and typically takes less than 1 minute for a each area the size of a typical neurofibroma.
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.
FCN-159 is a highly active MEK1/2 inhibitor that was designed, synthesized and screened on the basis of the structure of trametinib. FCN-159 is an orally available and highly potent selective inhibitor of MEK1/2, which is expected to be a targeted therapy for the treatment of advanced solid tumors and neurofibromatosis type 1.
A global study to demonstrate the effectiveness of selumetinib in participants with NF1 who have symptomatic, inoperable plexiform neurofibromas.
This is an open trial of the UCLA PEERS protocol delivered via Telehealth with teens with neurofibromatosis type 1 whose parents report that they have difficulty making and keeping friends.
This study will evaluate the tolerability and effectiveness of three FDA-approved treatments in Neurofibromatosis Type 1 Cutaneous Neurofibromas. These treatments are: a 1064nm laser, a 755nm laser, and a Kybella injection. Each patient will have a treatment and a control site.
A Phase 1 Open Label Study to Assess the Safety, Tolerability, Pharmacokinetics and Clinical Efficacy of Selumetinib, a Selective Mitogen Activated Protein Kinase Kinase (MEK) 1 Inhibitor, in Chinese Paediatric and Adult Subjects with Neurofibromatosis Type 1 (NF1) and Inoperable Plexiform Neurofibromas (PN).
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.
Subjects with Neurofibromatosis Type 2 (NF2) and progressive vestibular schwannoma (VS) will be treated with crizotinib administered orally. Crizotinib will be taken continuously until disease progression or unacceptable toxicity, in continuous treatment cycles of 28 days each, for a maximum of 12 cycles.
