Intermittent Selumetinib for Uveal Melanoma

NCT02768766

Description:

The purpose of this study is to find out what effects, good and/or bad, intermittent dosing of the drug Selumetinib will have on subjects with uveal melanoma. Selumetinib is a drug that blocks (or turns off) methyl ethyl ketone (MEK), a protein activated in some uveal melanoma cells. Selumetinib is a MEK inhibitor. Blocking MEK may stop the cancer from growing.

Purpose

The purpose of this study is to find out what effects, good and/or bad, intermittent dosing of the drug Selumetinib will have on subjects with uveal melanoma. Selumetinib is a drug that blocks (or turns off) methyl ethyl ketone (MEK), a protein activated in some uveal melanoma cells. Selumetinib is a MEK inhibitor. Blocking MEK may stop the cancer from growing.

Detailed Description

      Uveal melanoma (UM) is the most common primary intraocular malignancy in adults, and arises
      from melanocytes within the choroid plexus of the eye. The development of metastasis is
      common and occurs in approximately 50% of patients with posterior UM within 15 years of
      initial diagnosis and treatment. As no effective systemic therapy has yet been identified
      for this disease, outcomes for metastatic UM are poor with a median survival of 12 months.

      There is no FDA approved therapy for patients with advanced UM. Studies have shown that
      inhibition of the MAPK pathway with the MEK inhibitor selumetinib (hyd-sulfate AZD6244) is
      an effective therapy for uveal melanoma but despite this treatment, cures are not achieved.
      Although drugs such as selumetinib have been studied when patients take the treatment every
      day, research has shown that in some cases, it may be better to use the treatment on an
      intermittent schedule. Such a strategy may reduce the side effects, allow higher doses of
      the drug to be used, more completely block the MAPK pathway, and prevent the development of
      drug resistance mechanisms within the tumor.

        Inclusion Criteria:

          -  Histopathologically confirmed diagnosis of metastatic or unresectable uveal melanoma.
             Note - Documentation of mutation status for uveal melanoma will not be required

             contraception (hormonal or barrier method of birth control; abstinence) prior to

             or her partner is participating in this study, she should inform her treating
             physician immediately. Men treated or enrolled on this protocol must also agree to
             use adequate contraception prior to the study, for the duration of study
             participation, and 3 months after completion of selumetinib administration.

        Exclusion Criteria:

          -  Patients who have had chemotherapy or immunotherapy within 4 weeks or radiation
             therapy within 2 weeks prior to entering the study or those who have not recovered
             from adverse events due to agents administered more than 4 weeks earlier.

          -  Patients who are receiving any other investigational agents concurrently. Palliative
             radiation therapy will be allowed as long as the patient meets all other eligibility
             criteria.

          -  Have had recent major surgery within a minimum 4 weeks prior to starting study
             treatment, with the exception of surgical placement for vascular access.

          -  History of allergic reactions attributed to compounds of similar chemical or biologic
             composition to selumetinib

          -  Every effort must be made to avoid the use of a concomitant medication that can
             prolong the corrected QT (QTc) interval while receiving selumetinib (hyd-sulfate
             AZD6244). If the patient cannot discontinue medications that prolong QTc interval
             while receiving selumetinib, close cardiac monitoring should be performed.

          -  Patients with QTc interval >450 msecs or other factors that increase the risk of QTc
             prolongation or arrhythmic events (ex. Heart failure, hypokalemia, family history of
             long QT syndrome) including heart failure that meets New York Heart Association
             (NYHA) class III and IV definitions (see Appendix A) are excluded.

          -  Prior or current cardiomyopathy including but not limited to the following: known
             hypertrophic cardiomyopathy, known arrhythmogenic right ventricular cardiomyopathy,
             previous moderate or severe impairment of left ventricular systolic function (LVEF
             <45% on echocardiography or equivalent on MuGA) even if full recovery has occurred.

          -  Atrial fibrillation with a ventricular rate >100 bpm on ECG at rest

          -  Baseline Left ventricular ejection fraction (LVEF) below the LLN or <55% measured by
             echocardiography or institution's LLN for MUGA

          -  Severe valvular heart disease

          -  Uncontrolled Angina - Canadian Cardiovascular Society grade II-IV despite medical
             therapy

          -  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 selumetinib may be teratogenic or
             have abortifacient effects. Because there is an unknown but potential risk for
             adverse events in nursing infants secondary to treatment of the mother with
             selumetinib, breastfeeding should be discontinued if the mother is treated with
             selumetinib.

          -  HIV positive patients on combination antiretroviral therapy are ineligible because of
             the potential for pharmacokinetic interactions with selumetinib.

          -  Prior treatment with a MEK, Ras or Raf inhibitor

          -  History of current evidence/risk of retinal vein occlusion (RVO) or retinal pigment
             epithelial detachment (RPED) in the eye unaffected by uveal melanoma; intraocular
             pressure (IOP) >21mmgHG or uncontrolled glaucoma

          -  History of interstitial lung disease or pneumonitis

          -  Patients with known Hepatitis B or C

          -  Refractory nausea and vomiting, active gastrointestinal disease (e.g. inflammatory
             bowel disease), or significant bowel resection that would preclude adequate
             absorption

          -  Have known or suspected brain metastases or spinal cord compression, unless the
             condition has been asymptomatic, has been treated with surgery and / or radiation,
             and has been stable for at least 4 weeks prior to the first dose of study medication

          -  Any unresolved toxicity ≥ CTCAE Grade 2 from previous anti-cancer therapy, except for
             alopecia

          -  Have evidence of any other significant clinical disorder or laboratory finding that,
             as judged by the investigator, makes it undesirable for the patient to participate in
             the study.

          -  Patients being actively treated for a secondary malignancy
