Innovative Trial for Understanding the Impact of Targeted Therapies in NF2-Related Schwannomatosis (INTUITT-NF2)

Exclusion Criteria88

• 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 SUB-STUDY A (Brigatinib arm): CLOSED TO ENROLLMENT
• 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
• Eligibility Criteria Specific to SUB-STUDY B (Neratinib arm):
• Participants must be willing and able to provide written informed consent/assent for the neratinib arm of the INTUITT-NF2 trial.
• Participant must be ≥ 12 years of age and have body weight ≥ 40 kg on Day 1 of treatment.
• Patient must be able to swallow pills.
• Recovery (ie, to Grade 1 or baseline) from all clinically significant AEs related to prior therapies (excluding alopecia, neuropathy, and nail changes).
• Clinical laboratory values as specified below within 14 days before the first dose of study drug:
• ALT/aspartate aminotransferase (AST) ≤ 2.5 × institutional upper limit of normal (ULN);
• Total serum bilirubin ≤ 1.5 × institutional ULN (<3.0 × institutional ULN for patients with Gilbert syndrome)

• Serum lipase ≤1.5 × institutional ULN
• Absolute neutrophil count ≥1.5 × 109/L
• Platelet count ≥75 × 109/L
• Hemoglobin ≥9 g/dL
• Left ventricular ejection fraction (LVEF) ≥50% measured by multiple-gated acquisition scan (MUGA) or echocardiogram (ECHO).
• It is not known what effects neratinib has on human pregnancy or development of the embryo or fetus. Therefore, 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. Neratinib 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.
• Female patients must have negative β-human chorionic gonadotropin (hCG) pregnancy test for premenopausal women of reproductive capacity (those who are biologically capable of having children) and for women less than 12 months after menopause. \[Women are considered postmenopausal if they are ≥12 months without menses, in the absence of endocrine or anti-endocrine therapies.\]
• 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 28 days 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 neratinib. Minor surgical procedures such as catheter placement or minimally invasive biopsies are allowed.
