Trial of Selumetinib in Patients With Neurofibromatosis Type II Related Tumors

Study Purpose

In this research study the researchers want to learn more about the effects (both good and bad) the study drug selumetinib has on participants with neurofibromatosis type II (NF2) related tumor. The researchers are asking patients with NF2 related tumors to be in the study, because their hearing has decreased and/or their NF2 related tumor has started to grow. The goals of this study are:

  • - Determine if selumetinib will stop NF2 related tumors from growing - Measure the changes in hearing after receiving selumetinib for 6 months.
  • - Determine if selumetinib improves how participants feel (physically and emotionally) and how participants can perform daily activities.
  • - Examine tumor tissue, if available, in a laboratory to see if NF2 related tumors have targets of selumetinib.

Exclusion Criteria:

  • - Pregnant or breast-feeding women will not be entered on this study due to risks of fetal and teratogenic adverse events as seen in animal/human studies.
The effects of selumetinib on the developing human fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation, and for four weeks after dosing with selumetinib ceases. The selumetinib manufacturer recommends that adequate contraception for male patients should be used for 16 weeks post-last dose due to sperm life cycle. Women of child-bearing potential must have a negative pregnancy test prior to study registration. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Note: Female subjects are considered "of child-bearing potential" if they are anatomically and physiologically capable of becoming pregnant. For girls of normal reproductive potential, the possibility of becoming pregnant requires ovulatory menstrual cycles and heterosexual intercourse. Although the timing of ovulation relative to menarche is variable, there is consistent evidence that some girls may have ovulatory cycles prior to menarche, and that, in healthy populations, regular ovulation may begin within a few months of menarche. Therefore, menarche is the most feasible clinical indicator of the biological potential for pregnancy.
  • - Patients with any clinically significant unrelated systemic illness (serious infections or significant cardiac, pulmonary, hepatic or other organ dysfunction) that is likely to interfere with the study procedures or results - Patients who are currently receiving another investigational drug within 4 weeks prior to the first dose of study treatment, or within a period during which the investigational drug or systemic anticancer treatment has not been cleared from the body (e.g. a period of 5 'half-lives'), whichever is the most appropriate and as judged by the investigator are not eligible.
  • - Patients who have taken another BRAF inhibitor such as Vemurafenib or Dabrafenib prior to study registration are not eligible.
Prior treatment with selumetinib or another MEK inhibitor is not allowed.
  • - Patients with QTc interval of > 450 msec - Patients who require enzyme inducing anti-convulsants to control seizures.
  • - Anticoagulation: Patients receiving coumadin are eligible but must have their PT and INR monitored prior to each 4 week course.
  • - Patients who in the opinion of the investigator may not be able to comply with the safety monitoring requirements of the study are not eligible.
  • - The following cardiac conditions: a.
Uncontrolled hypertension in adults (BP ≥ 140/90 mmHg despite medical therapy) b. Acute coronary syndrome within 6 months prior to starting treatment c. Uncontrolled Angina
  • - Canadian Cardiovascular Society grade II-IV despite medical therapy (Appendix H) d.
Symptomatic heart failure NYHA Class II-IV, prior or current cardiomyopathy, or severe valvular heart disease (Appendix I) e. Prior or current cardiomyopathy including but not limited to the following: i. Known hypertrophic cardiomyopathy ii. Known arrhythmogenic right ventricular cardiomyopathy f. Previous moderate or severe impairment of left ventricular systolic function (LVEF <45% on echocardiography or equivalent on MuGA) if known even if full recovery has occurred. g. Severe valvular heart disease h. Baseline Left ventricular ejection fraction (LVEF) below the LLN or <50% measured by echocardiography or institution's LLN for MUGA i. Atrial fibrillation with a ventricular rate >100 bpm on ECG at rest
  • - Ophthalmological conditions as follows: 1.
Current or past history of retinal pigment epithelial detachment (RPED)/central serous retinopathy (CSR) or retinal vein occlusion 2. Intraocular pressure (IOP) > 21 mmHg or uncontrolled glaucoma (irrespective of IOP)
  • - No major surgery within 4 weeks of starting selumetinib.
Portacath insertion, G Tube placement, and insertion of ventriculoperitoneal shunt are not considered major surgeries.
  • - History of allergic reactions attributed to compounds of similar chemical or biologic composition to selumetinib - History of a medical or psychiatric illness, that in the investigator's judgment renders the patient incapable of further therapy on this protocol - Patients with progressive disease associated with significant or disabling clinical symptoms requiring immediate intervention with surgery or radiation therapy are not eligible.

Additional Details

This is a Phase 2 trial to assess the hearing response rate and radiographic response of VS in children and young adults with NF2 who are treated with selumetinib. Dosing will be based on age: For patients with NF2 who are 3 to < 18 years of age, dosing will be based on BSA. Dosing is based on BSA calculated at the beginning of each course. For patients with NF2 who are ≥ 18 to 45 years of age, dosing will be the standard adult dose of 75 mg BID. Selumetinib is taken orally twice a day continuously. One course is equivalent to 28 days. Therapy may continue for up to two years (26 courses) in the absence of disease progression or unacceptable toxicity. There will be two treatment strata. Stratum 1 is for those patients who have a target vestibular schwannoma which is causing hearing loss. Stratum 2 will be reserved for patients who exhibit growth of a tumor(s) besides vestibular schwannoma and are therefore not eligible for stratum 1.

Arms & Interventions

Arms

Experimental: Stratum 1 - NF2 related vestibular schwannomas

Stratum 1 will include patients with NF2 with vestibular schwannomas who exhibit hearing loss. Participants will receive continuous twice daily dosing of selumetinib. Dosing for children (less than 18 is 25 mg/m2/dose) and dosing for adults is fixed 75 mg/dose.

Experimental: Stratum 2: other NF2 related tumors (meningiomas and ependymom

Stratum 2 will include patients who have progressive lesions other than VS (including non-vestibular schwannomas, meningiomas, and spinal cord lesions). Participants will receive continuous twice daily dosing of selumentinib. Dosing for children (less than 18 is 25 mg/m2/dose) and dosing for adults is fixed 75 mg/dose.
