Neurofibromatosis Clinical Trials Consortium
Overview | Consortium History | Management and Oversight | Research Site Details | Approved Trial Details | NFRP Clinical Trials
The Neurofibromatosis Clinical Trials Consortium (NFCTC, http://www.uab.edu/nfconsortium) was established by the Department of Defense Neurofibromatosis Research Program (NFRP) to develop and perform clinical trials for the treatment of neurofibromatosis (NF) complications in children and adults. The Consortium is composed of fifteen clinical sites, ten collaborating affiliate sites, and an Operations Center at the University of Alabama at Birmingham under the direction of Dr. Bruce Korf. The purpose of the Operations Center is to provide administrative, data management, and statistical support to the NFCTC. Each of the clinical and collaborating sites has expertise in the treatment and management of NF and an established patient population available for clinical trials.

Approved NFCTC Clinical Trials (FY06 NFRP Award)
(1) STOPN: Sirolimus for the Treatment of NF1-Related Plexiform Neurofibromas
STOPN was a Phase II clinical trial to evaluate the mTOR inhibitor sirolimus in the treatment of plexiform neurofibromas in children and adults with NF1. The goals of this trial were to find out if sirolimus could stop or slow the growth of and/or shrink plexiform neurofibromas, evaluate the feasibility and toxicity of chronic sirolimus administration, and characterize the active pharmacokinetic profile of sirolimus when administered to this patient population.
Status: Completed
ClinicalTrials.gov Identifier: NCT00634270
Outcome: In the progressive disease stratum, the data indicated that sirolimus can increase time to progression in NF1 patients with progressive plexiform neurofibromas. In the non-progressive disease stratum, the researchers observed that sirolimus treatment did not lead to decreased tumor volume.

(2) STARS: Lovastatin for the Treatment of Learning Disabilities in Children with NF1
STARS was a placebo-controlled, double-blind Phase II clinical trial to evaluate the effectiveness of lovastatin in the treatment of learning disabilities in children with NF1. The goals of this study were to determine whether lovastatin significantly improves visual spatial learning and/or sustained attention in children with NF1, affects measures of executive function, behavior, and quality of life in children with NF1 and cognitive deficits, and is safe and tolerable in this population.
Status: Completed.
ClinicalTrials.gov Identifier: NCT00853580
Outcome: No improvement in the primary outcome measures was observed. The research team examined the data from this trial further in an effort to help inform future trials. They found that single observed endpoints are not appropriate for use in efficacy studies due to variable test-retest reliability. The team also evaluated the relationships between functional outcomes and cognition and ADHD symptoms; they found that ADHD symptoms (irrespective of cognitive deficits) negatively impact functioning in children with NF1.

(3) RAD001: RAD001 for Children with NF1 and Chemotherapy-Refractory Radiographic Progressive Low-Grade Gliomas
This trial was a single-arm Phase II trial to evaluate the effectiveness of RAD001 (everolimus) in the treatment of pediatric patients with NF1 and low-grade gliomas (brain tumors and optic gliomas) that have not responded to standard therapies. In addition to evaluating the clinical response to RAD001, the safety of this drug was evaluated in this patient population.
Status: Completed
ClinicalTrials.gov Identifier: NCT01158651
Outcome: Everolimus was well-tolerated by the participants in the study. Fifteen of the 22 participants in the study experienced tumor shrinkage or no tumor growth, with 10 of those remaining free of progression during follow-up. The study indicates that everolimus should be considered for therapy in this patient population. In addition, amongst those with an optic pathway glioma, the majority had stable visual acuity after treatment with everolimus.

(4) RAD001 in Combination with Bevacizumab for Patients with Sporadic and NF1-Related Refractory MPNST
This Phase II clinical trial evaluated the use of RAD001 (everolimus) in combination with bevacizumab for patients with sporadic and NF1-related refractory MPNST. The primary goals of this trial were to evaluate the clinical benefit of treatment of chemotherapy refractory MPNST with RAD001 in combination with bevacizumab, and assess the toxicity and safety of this drug combination. This study was performed in collaboration with the Sarcoma Alliance for Research through Collaboration (SARC) and was funded by award NF093105.
Status: Completed
ClinicalTrials.gov Identifier: NCT01661283
Outcome: The combination of everolimus and bevacizumab did not reach the study's target response rate and is not considered active in refractory malignant peripheral nerve sheath tumors.

Approved NFCTC Clinical Trials (FY11 NFRP Award)
(1) Bevacizumab for NF2-Related Progressive Vestibular Schwannomas
This study is an open-label, Phase II clinical trial to evaluate bevacizumab in children and young adults with NF2 and progressive vestibular schwannomas that are poor candidates for standard treatment with surgery or radiation. The primary objective of this study is to determine the hearing response rate after beginning treatment with bevacizumab for symptomatic vestibular schwannomas in children and young adults with NF2.
Status: Active, not recruiting
ClinicalTrials.gov Identifier: NCT01767792
Outcome: High-dose and standard-dose bevacizumab seem to be similarly effective for treatment of patients with NF2 with hearing loss. Unlike adults, pediatric participants did not experience tumor shrinkage. However, adult and pediatric cohorts reported similar improvement in QOL. Treatments incorporating bevacizumab should be considered for children with NF2.

Outcome: Mirdametinib had a partial response rate of 42%
(4) INFUSE Bone Graft for Treatment of NF1-Related Tibial Pseudarthrosis (TPA)
This Phase II clinical trial was planned to evaluate the utility of adding BMP-2 at the surgical site of TPA repair in children and adolescents with NF1 with regard to improved bone healing. In addition to evaluating the clinical response to, the safety of this drug was to be evaluated in a pediatric NF1 population.
Status: Active, not recruiting
ClinicalTrials.gov Identifier: NCT02718131
Outcome: The study was unable to enroll sufficient participants to meet the objectives of the trial. The research team has provided recommendations for future studies of orthopedic manifestations of NF1.
