Study summary

This study, "A Phase II Study of Cabozantinib (XL l84) for Plexiform Neurofibromas in Subjects with Neurofibromatosis Type I in Children and Adults diagnosed with Neurofibromatosis Type 1 (NF1) and have a type of tumor called a plexiform neurofibroma (PN). Neurofibromas are tumors that develop from the cells and tissues that cover the nerves. Plexiform neurofibromas can be disfiguring, painful, and life-threatening. These types of tumors typically do not respond well to most treatment approaches such as chemotherapy, radiation, and surgery because of their slow growth and location near vital structures of the body such as nerves, blood vessels, and the airway.

The primary objective is to determine the response rate of NF1 patients with plexiform neurofibromas treated with Cabozantinib therapy using MRI scans. The objective response rate to cabozantinib is defined as ≥ 20% reduction in tumor volume at the end of 12 cycles.

Read the detailed description

There are two cohorts: Cohort A is for patients ≥ 16 years of age and Cohort B is for patients 3 - 15 years of age. Cohort A is closed to enrollment but this study will open to Cohort B patients. This phase II open label study will evaluate adults and children with NF1 and plexiform neurofibromas treated with cabozantinib (XL184). This study will enroll subjects who either meet clinical diagnostic criteria or have an identified pathogenetic NF1 mutation. Subjects on study must have clinically significant plexiform neurofibroma defined as potentially life-threatening, impinging on vital structures or significantly impairing the quality of life from pain or other symptoms. Patients must not have lesions suspicious for malignant tumors such as MPNSTs (malignant peripheral nerve sheath tumors) and suspicious tumors must be proven negative by histopathology prior to enrollment on study. Since Cohort A is closed to accrual, this study will be open to Cohort B, patients 3 - 15 years of age that meet eligibility criteria.

For Cohort A, the study will be a Simon two-stage study design. It will be a single-arm open-label study of cabozantinib and the primary endpoint is the objective response rate (ORR) to cabozantinib at 1 year. In the first stage, 9 evaluable subjects will be accrued. If there is at least 1 response, accrual will continue to the second stage and an additional 8 evaluable subjects will be enrolled. To allow for 25% unevaluable subjects, a maximum of 24 subjects will be enrolled. Radiographic response will be evaluated as the primary endpoint with 20% volumetric MRI response of the target lesion being the threshold criteria for tumor response. A target lesion will be selected at time of enrollment and tumor evaluations will occur serially while on study.

For Cohort B, a minimum of 17 evaluable subjects will be enrolled. To allow for up to 25% unevaluable subjects, a minimum of 24 subjects will be enrolled. Based on preliminary response data and minimal toxicity in Cohort A, a 2-stage design is not felt to be necessary for Cohort B.

In Cohort A, all subjects will start cabozantinib at 40 mg. The published maximum tolerated dose (MTD) for Cabozantinib is 140 mg and the current recommended dose in Phase 3 clinical trials for subjects with medullary thyroid cancer is 100 mg. Doses of 40 mg and 60 mg continue to show efficacy in on-going phase 2 and phase 3 trials with reduced toxicity. Subjects who tolerate 40 mg for 2 cycles will escalate to 60 mg. The rationale for this is that the majority of subjects who develop toxicity do so after >2 weeks on drug as cabozantinib has a long half-life. Subjects who experience dose-limiting toxicity at 40 mg will dose reduce to 20 mg when their toxicities resolve. Subjects without toxicity at 40mg will increase to 60mg. Subjects who experience toxicity at 60 mg will dose reduce to 40 mg. This dosing schema is designed to maximize safety and tolerability in this new population of patients.

In Cohort B, subjects will start at 30 mg/m2/day dosing. Dose will be escalated at cycle 3 if tolerated to 40 mg/m2. Subjects who experience DLT at 40 mg/m2/day will dose reduce to 30 mg/m2/day. Subjects who experience DLT at 30 mg/m2/day will dose reduce to 23 mg/m2day. Actual dosing will be based on the dosing nomogram.

Dosing will be continuous, with 28 days defined as a cycle and each cycle reporting period is day 1 to day 28. In the absence of progressive disease or dose limiting toxicity (DLT), subjects may continue on therapy for a total of 12 total cycles. Subjects who have a radiographic response (20% or greater reduction in tumor volume) on therapy at the end of 12 cycles can continue on therapy for up to an additional year. The maximum duration for treatment under this study design is 24 cycles. However, subjects who do not achieve at least 15% reduction in index tumor volume after 8 cycles (\~8 months) will be considered treatment failures and taken off study. Subjects entered on the trial will be carefully monitored for the development of cabozantinib associated toxicities, and target modifications and interruptions will be performed.

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, if subject is a child,by the site Principal Investigator or designated associate investigator. When appropriate, pediatric patients will be included in all discussions. 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

Schedule of study evaluations are summarized below:

Pre-Study:

  • Medical history, physical exam with vital signs, blood pressure, and pulse oximetry
  • Performance status to assess your ability to perform everyday tasks
  • Laboratory tests including blood and urine tests for routine safety tests

  • MRI of neurofibromas
  • Completion of health-related questionnaires on quality of life, pain assessment, and PN symptom checklist (upon study entry)
  • Research blood draws ( 2 tablespoons) to evaluate the tumor's response to treatment and the action of cabozantinib in the body over a period of time (Upon study entry on Cycle 1 Day 1, predose and 4-hours post dose)

During Study Treatment:

End of Cycles 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 16, 18, 20, 22, 24 or Early Termination (additional visit that is not within the specified times mentioned.)

Cycles 1, 2, 3, 4

  • Research blood draws ( 2 tablespoons) to evaluate the tumor's response to treatment and the action of cabozantinib in the body over a period of time

Phone Calls will be made at the end of cycles 13, 15, 17, 19, 21, and 23 to assess drug compliance and toxicity

The protocol PI and clinical coordinator will review the subject eligibility, study progress, safety issues, protocol deviations and adverse events. A Data Safety Monitoring Board (DSMB) and a medical monitor has been established for the purpose of ensuring data compliance and regular monitoring of this trial. The medical monitor is a qualified physician and is not associated with this particular protocol. The medical monitor is specifically required to review all unanticipated problems involving risk to subjects or others, serious adverse events and deaths associated with the protocol and provide an unbiased written report of the event.

An early stopping rule will be invoked for both cohorts to potentially prevent accrual of subjects onto the study in the event that Cabozantinib is associated with a higher than acceptable rate of dose-limiting toxicity (DLT) requiring removal from study (set at 10% or higher) during the first 2 cycles. 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 DLT, then accrual will be stopped until the DSMB reviews safety and efficacy data for the study and recommends termination or despite the DLT (because of the benefit:risk assessment or other reasoning) recommends reopening recruitment. Boundaries for DSMB for consideration of terminating each cohort (both cohort A and B) would be the same.

The sample size for this trial is based on the safety and feasibility factors. The data needed is based on risk versus benefit. For feasibility, we expect at least efficacy of a 25% response rate. For safety reasons, subjects who do not achieve at least a 15% reduction in tumor volume will not be continued beyond 8 courses, as the likelihood of achieving a response (20% reduction in tumor volume) by 12 months is minimal. These subjects will be discontinued from the trial and counted in an "Intent to Treat" analysis as evaluable and as failures.

All analyses for outcome results will be based on evaluable subjects. Definitions of evaluable include: 1.) Evaluation for toxicity (subject who received at least one dose of study drug and removed from treatment for toxicity are evaluable. Any subject who completed one full cycle of therapy is evaluable for toxicity); 2.)Evaluation for response (subjects who have completed at least two cycles of therapy and have had their first follow-up MRI evaluation. Subjects who did not respond and are later found to have a target tumor other than a plexiform neurofibroma (e.g. malignant peripheral nerve sheath tumor) are not evaluable for response).

    Cohort A (≥ 16 years - closed to accrual): Starting cabozantinib of 40 mg daily by mouth per cycle. Duration of each cycle is 28 days. Subjects will dose escalate after 2 cycles to 60 mg based on dose tolerability. Subjects who do not tolerate 40 mg will dose reduce to 20 mg. Doses will be capped at 60 mg. Cohort B (3 - 15 years). The starting cabozantinib dose is 30 mg/m2/day by mouth per cycle. Duration of each cycle is 28 days. Subjects will dose escalate after 2 cycles to 40 mg/m2/day based on dose tolerability. Subjects who do not tolerate 30 mg/m2/day will dose reduce to 23 mg/m2/day. Doses will be capped at 60 mg/day max daily dose Each cohort will enroll up to 24 evaluable subjects with a target minimum of 17 evaluable subjects per cohort.

    Drug: Cabozantinib

Interventions

  • DrugCabozantinib

    This is an open label Phase II clinical trial. For both cohorts, subjects will receive cabozantinib orally in continuous cycles. Each cycle is 28 days. In absence of progressive disease or dose limiting toxicity (DLT), subjects may continue therapy for a total of 24 cycles. Subjects with radiographic response (20% or greater reduction in tumor volume) at the end of 12 cycles can continue on therapy for up to an additional year. However, for Cohort A, subjects who do not achieve 15% reduction in tumor volume after 8 cycles will be considered treatment failure and taken off study. For Cohort B, the criteria that subjects who do not achieve 15% reduction by 8 cycles are considered treatment failure and taken off study was eliminated. Subjects will be carefully monitored for toxicities associated with cabozantinib.
