About this study
Official title: A Phase II Study of Binimetinib in Children and Adults With NF1 Associated Plexiform Neurofibromas (PNOC010)
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.
Read the detailed description
Patients ≥ 1 year with progressive NF1 and PN(s) by serial imaging or causing significant morbidity and that can be analyzed by volumetric MRI are eligible for this study. Initially, the study will open to adult patients,18 years and older, (Stratum A). The pediatric patients (Statum B) will be receive the pediatric maximum tolerated dose (MTD) of binimetinib that is currently being established in an ongoing phase 1 study (NCT02285439). For adult subjects, binimetinib (established adult RP2D) is taken orally twice a day. Dosing will be continuous, with 28 days defined as a course and will continue for a total of 24 courses or until one of the Off Treatment or Off Study criteria are met. Subjects will undergo volumetric assays of their targeted PN using MRI after every 4 courses for the first year and then every 6 courses. MRI review of the volumetric assays will occur centrally under the guidance of Dr. Dombi at NCI. Subjects may receive additional courses beyond course 8 only if there is at least a 15% reduction in volume of the target tumor, as measured from baseline. Treatment beyond course 12 will be only be given to those subjects who achieve a response of ≥ 20% tumor shrinkage by volumetric analysis and can continue on therapy up to an additional year for a maximum of 24 total courses. For those who respond to binimetinib after 12 courses, an MRI scan of the target lesion must be performed at 4 and 12 months after stopping drug in order to determine whether response is maintained post-therapy. Subjects will be carefully monitored for development of binimetinib associated toxicities. Subjects will be removed from the study for significant toxicity, treatment delay of ≥ 21 days, or objective progression of tumor growth by ≥ 20% by volumetric analysis at any time.
The investigational nature and objectives of this trial, the procedures and treatment involved, the risks, discomforts, and benefits, and potential alternatives therapies will be carefully explained to the subject and/or subject's parent(s) or guardian by the site Principal Investigator or designated associate investigator. A signed informed consent document will be obtained prior to determining eligibility and entry criteria to this trial. Subjects entered on this trial will be treated with therapeutic intent and response to therapy will be closely monitored. This protocol involves greater than minimal risk but presents the potential for direct benefit to individual subjects.

The sample size is 20 subjects for each adult and children cohorts with a minimum target of 17 evaluable subjects per cohort. Evaluable is defined as: any subjects who received ≥ one dose of binimetinib and had a ≥ Grade 3 binimetinib associated toxicity, or in absence of a ≥ Grade 3 toxicity, any subjects who completed one full course of therapy; subjects who have completed at least two courses of therapy and had their first follow-up MRI evaluation except for discovery of a target tumor other than a PN; and any subjects who has at least two samples drawn for plasma cytokines/growth factors, one at baseline and at least one other after starting therapy.
Data Safety Monitoring Board (DSMB) and a Medical Monitor have been established for this study for the purpose of ensuring data compliance and regular monitoring. An early stopping rules have been defined within the protocol. The early stopping rule will invoked for both Strata separately to potentially prevent accrual subjects onto the study in the event that binimetinib is associated with a higher than acceptable rate of dose-limiting toxicity (DLT) requiring removal from study (10% or higher) during the first 2 courses. Toxicity will be continuously monitored. If at any time >2 of the first 10 subjects or 4 or more of the first 15 total subjects are removed for toxicity, then accrual will be stopped until the DSMB reviews the safety and efficacy data for the study. Based on the review, the DSMB can either recommend termination of the study or reopen recruitment. The Medical Monitor is a qualified physician who is not associated with this protocol and is a member of the DSMB. The Medical Monitor may perform oversight functions duties: may discuss the research protocol with the investigators, interview human subjects, and consult with others outside of the study about the research; shall have the authority to stop the research protocol in progress, remove individual subjects from protocol, and take whatever steps are necessary to protect the safety and well being of human subjects until the Institutional Review Board (IRB) can assess the monitor's report; and shall have the responsibility to promptly report the observation and findings to the IRB or other designated official/organization. The Medical Monitor is specifically required to review and provide written report of all unanticipated problems involving risk to subjects or others and serious adverse events.
In addition, as part of the Data Safety Monitoring Plan, the Study Chairs and the NF Consortium Clinical Research Nurse Manager will review subject eligibility, study progress, safety issues, protocol deviations and adverse events. Monthly reports will be generated by the NF Consortium Data Management Center to assess completeness of data. Monthly phone conferences will take place between NF Consortium Operations Center and the Protocol Team to address data issues.
The sample size for this trial is based on safety and feasibility factors. The data needed for safety is based on risk versus benefit, and for feasibility, we expect at least efficacy of 25% response rate. For safety reasons, subjects who do not achieve at least 15% reduction in volume of target tumor after 8 courses will be discontinued from the trial, as the likelihood of achieving a 20% reduction in tumor volume by 12 months is minimal. Safety analysis set will be described and summarized based on information regarding study treatment administrations, drug dosing and course compliance, and safety variables (e.g. adverse events/serious adverse events). All analyses for outcome results will be based on evaluable subjects. Given the difference in the clinical behavior of PN in the adults and pediatric subjects, the adult and children stratum will be analyzed independently.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.
Detailed description
Patients ≥ 1 year with progressive NF1 and PN(s) by serial imaging or causing significant morbidity and that can be analyzed by volumetric MRI are eligible for this study. Initially, the study will open to adult patients,18 years and older, (Stratum A). The pediatric patients (Statum B) will be receive the pediatric maximum tolerated dose (MTD) of binimetinib that is currently being established in an ongoing phase 1 study (NCT02285439). For adult subjects, binimetinib (established adult RP2D) is taken orally twice a day. Dosing will be continuous, with 28 days defined as a course and will continue for a total of 24 courses or until one of the Off Treatment or Off Study criteria are met. Subjects will undergo volumetric assays of their targeted PN using MRI after every 4 courses for the first year and then every 6 courses. MRI review of the volumetric assays will occur centrally under the guidance of Dr. Dombi at NCI. Subjects may receive additional courses beyond course 8 only if there is at least a 15% reduction in volume of the target tumor, as measured from baseline. Treatment beyond course 12 will be only be given to those subjects who achieve a response of ≥ 20% tumor shrinkage by volumetric analysis and can continue on therapy up to an additional year for a maximum of 24 total courses. For those who respond to binimetinib after 12 courses, an MRI scan of the target lesion must be performed at 4 and 12 months after stopping drug in order to determine whether response is maintained post-therapy. Subjects will be carefully monitored for development of binimetinib associated toxicities. Subjects will be removed from the study for significant toxicity, treatment delay of ≥ 21 days, or objective progression of tumor growth by ≥ 20% by volumetric analysis at any time.
The investigational nature and objectives of this trial, the procedures and treatment involved, the risks, discomforts, and benefits, and potential alternatives therapies will be carefully explained to the subject and/or subject's parent(s) or guardian by the site Principal Investigator or designated associate investigator. A signed informed consent document will be obtained prior to determining eligibility and entry criteria to this trial. Subjects entered on this trial will be treated with therapeutic intent and response to therapy will be closely monitored. This protocol involves greater than minimal risk but presents the potential for direct benefit to individual subjects.

The sample size is 20 subjects for each adult and children cohorts with a minimum target of 17 evaluable subjects per cohort. Evaluable is defined as: any subjects who received ≥ one dose of binimetinib and had a ≥ Grade 3 binimetinib associated toxicity, or in absence of a ≥ Grade 3 toxicity, any subjects who completed one full course of therapy; subjects who have completed at least two courses of therapy and had their first follow-up MRI evaluation except for discovery of a target tumor other than a PN; and any subjects who has at least two samples drawn for plasma cytokines/growth factors, one at baseline and at least one other after starting therapy.
Data Safety Monitoring Board (DSMB) and a Medical Monitor have been established for this study for the purpose of ensuring data compliance and regular monitoring. An early stopping rules have been defined within the protocol. The early stopping rule will invoked for both Strata separately to potentially prevent accrual subjects onto the study in the event that binimetinib is associated with a higher than acceptable rate of dose-limiting toxicity (DLT) requiring removal from study (10% or higher) during the first 2 courses. Toxicity will be continuously monitored. If at any time >2 of the first 10 subjects or 4 or more of the first 15 total subjects are removed for toxicity, then accrual will be stopped until the DSMB reviews the safety and efficacy data for the study. Based on the review, the DSMB can either recommend termination of the study or reopen recruitment. The Medical Monitor is a qualified physician who is not associated with this protocol and is a member of the DSMB. The Medical Monitor may perform oversight functions duties: may discuss the research protocol with the investigators, interview human subjects, and consult with others outside of the study about the research; shall have the authority to stop the research protocol in progress, remove individual subjects from protocol, and take whatever steps are necessary to protect the safety and well being of human subjects until the Institutional Review Board (IRB) can assess the monitor's report; and shall have the responsibility to promptly report the observation and findings to the IRB or other designated official/organization. The Medical Monitor is specifically required to review and provide written report of all unanticipated problems involving risk to subjects or others and serious adverse events.
In addition, as part of the Data Safety Monitoring Plan, the Study Chairs and the NF Consortium Clinical Research Nurse Manager will review subject eligibility, study progress, safety issues, protocol deviations and adverse events. Monthly reports will be generated by the NF Consortium Data Management Center to assess completeness of data. Monthly phone conferences will take place between NF Consortium Operations Center and the Protocol Team to address data issues.
The sample size for this trial is based on safety and feasibility factors. The data needed for safety is based on risk versus benefit, and for feasibility, we expect at least efficacy of 25% response rate. For safety reasons, subjects who do not achieve at least 15% reduction in volume of target tumor after 8 courses will be discontinued from the trial, as the likelihood of achieving a 20% reduction in tumor volume by 12 months is minimal. Safety analysis set will be described and summarized based on information regarding study treatment administrations, drug dosing and course compliance, and safety variables (e.g. adverse events/serious adverse events). All analyses for outcome results will be based on evaluable subjects. Given the difference in the clinical behavior of PN in the adults and pediatric subjects, the adult and children stratum will be analyzed independently.
