Innovative Trial for Understanding the Impact of Targeted Therapies in NF2


Brief Summary

This is a multi-arm phase II platform-basket screening study designed to test multiple experimental therapies simultaneously in patients with neurofibromatosis type 2 (NF2) with associated progressive tumors of vestibular schwannomas (VS), non-vestibular schwannomas (non-VS), meningiomas, and ependymomas.

This Master Study is being conducted as a "basket" study that may allow people with multiple tumor types associated with NF2 to receive new drugs throughout this study. Embedded within the Master Study are individual drug substudies. - Investigational Drug Sub-study A: Brigatinib

Eligibility Specific For Master Protocol:

Inclusion Criteria:

  • Patients must have a pathogenic variant in the NF2 gene (either in the germline or in two NF2-related tumors) OR a confirmed diagnosis of NF2 by fulfilling National Institute of Health (NIH) criteria or Manchester criteria: The NIH criteria includes presence of:
    • Bilateral vestibular schwannomas, OR
    • First-degree relative with NF2 and EITHER unilateral eighth nerve mass OR two of the following: neurofibroma, meningioma, glioma, schwannoma, juvenile posterior subcapsular lenticular opacity. The Manchester criteria includes presence of:
    • Bilateral vestibular schwannomas, OR
    • First-degree relative with NF2 and EITHER unilateral eighth nerve mass OR two of the following: neurofibroma, meningioma, glioma, schwannoma, juvenile posterior subcapsular lenticular opacity, OR
    • Unilateral vestibular schwannoma AND any two of: neurofibroma, meningioma, glioma, schwannoma, juvenile posterior subcapsular lenticular opacity, OR
    • Multiple meningiomas (two or more) AND unilateral vestibular schwannoma OR any two of: schwannoma, glioma, neurofibroma, cataract. Subjects must have a target NF2-related tumor (VS, non-VS, meningioma, or ependymoma) with documented radiographic progression within the preceding 36 months of Master Study registration defined as either:
    • at least 20% increase in volume of enhancing tumor
    • at least 2 mm increase in greatest linear dimension of enhancing tumor Participants must have measurable disease, defined as:
    • VS, non-VS, or meningioma target lesions that can be accurately measured as at least 1 ml by volumetric MRI scan or in at least one dimension as ≥10 mm with conventional MRI scan. See protocol for the evaluation of measurable disease
    • Ependymoma target lesions measurable linearly. Participant must have a target NF2-related tumor with the following qualities:
    • Not amenable to surgery due to patient refusal or due to high risk for surgical complications (e.g., damage to nerve function). Participant must be ≥ 12 years of age on Day 1 of treatment. Life expectancy of greater than 1 year Karnofsky performance status ≥ 70 or ECOG PS 0 or 1 (see Appendix A). Ability to understand and the willingness to sign written informed consent and assent documents.
    • Must have established relationship with primary care physician and provide contact information

Exclusion Criteria:

  • Participants who have had chemotherapy within a minimum of 4 weeks prior to Master Study registration (or a minimum of 5 half-lives and resolution to baseline of toxicities unless there are irreversible toxicities from prior drug that do not influence risk of next drug).
  • Participants who have received radiation to the target tumor within the last 3 years prior to Master study registration.
  • Participants who are receiving any other investigational agents.
  • Participants with target or non-target nervous system tumors that, in the opinion of the treating investigator, are likely to require active treatment (including surgery) within 6 months of registration to the Master Study.
  • History of a different malignancy, unless (a) have been disease-free for at least 2 years and are deemed by the treating investigator to be at low risk for recurrence of that malignancy.
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
  • Pregnant women are excluded from this study because the experimental agents may have the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with these experimental agents, breastfeeding should be discontinued if the mother is treated. Eligibility Criteria Specific to the Brigatinib Arm (substudy A):

Inclusion criteria

  • Participants must meet all eligibility criteria outlined in the Master Study
  • Participants must be willing and able to provide written informed consent/assent for the brigatinib arm of the INTUITT-NF2 trial.
  • Participant is ≥ 12 years of age and has body weight at least 40 kg on Day 1 of treatment.
  • Patient must be able to swallow pills.
  • Clinical laboratory values as specified below within 28 days before the first dose of study drug, as described in the protocol document:
  • Female patients participating in this study should avoid becoming pregnant, and male patients should avoid impregnating a female partner. Non-sterilized female patients of reproductive age group and male patients should use effective methods of contraception through defined periods during and after study treatment as specified below: Female patients must meet 1 of the following:
  • Postmenopausal for at least 1 year before the screening visit, or
  • Surgically sterile, or
  • If they are of childbearing potential, agree to practice 2 effective methods of contraception from the time of signing of the informed consent form through 4 months after the last dose of study drug, or agree to completely abstain from heterosexual intercourse. Brigatinib may decrease effectiveness of hormonal contraceptives, therefore, women are recommended to use non-hormonal methods of contraception. Highly effective non-hormonal birth control for women of child bearing potential with male partners includes:
    • Sexual abstinence (no sexual intercourse)
    • Intrauterine device (IUD) or intrauterine system (IUS)
    • Bilateral tubal ligation (both tubes tied)
    • Vasectomized partner Male patients, even if surgically sterilized (i.e., status post-vasectomy) must agree to 1 of the following:
  • Practice effective barrier contraception during the entire study treatment period and through 4 months after the last dose of study drug, or completely abstain from heterosexual intercourse.

Exclusion criteria:

  • Female patients who are both lactating and breastfeeding or have a positive serum pregnancy test during the screening period or a positive urine pregnancy test on Day 1 before first dose of study drug (if applicable)
  • Any serious medical or psychiatric illness that could, in the investigator's opinion, potentially interfere with the completion of treatment according to this protocol
  • Treatment with any investigational products within 1 month or 5 half-lives (whichever is longer) before the first dose of study drug
  • Had major surgery within 30 days of the first dose of brigatinib. Minor surgical procedures such as catheter placement or minimally invasive biopsies are allowed.
  • Have significant, uncontrolled, or active cardiovascular disease (as outlined in the protocol):
  • Have uncontrolled hypertension (defined as an average systolic blood pressure >160 or an average diastolic blood pressure >100 for adults; for children: please refer to table in protocol
