Intermittent Selumetinib for Uveal Melanoma
Study Details
Study Description
Brief Summary
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 Mitogen-activated protein kinase (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.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Selumetinib Subjects will receive selumetinib (hyd-sulfate AZD6244) orally twice a day for three days followed by four days off in four week cycles starting at a dose of 125mg. The doses to be studied on a 3 day on, 4 day off schedule are 100mg, 125mg, 150mg, 175mg, 200mg and 225mg as per the time to event continual reassessment (TITE-CRM) design. |
Drug: Selumetinib
100mg, 125mg, 150mg, 175mg, 200mg or 225mg of oral capsules
An orally active, small molecule with potential antineoplastic activity. Selumetinib is an ATP-independent inhibitor of mitogen-activated protein kinase kinase (MEK) or MAPK/extracellular-signal-regulated kinase (ERK) kinase) 1 and 2. Inhibition of both MEK1 and 2 by selumetinib prevents the activation of MEK1/2 dependent effector proteins and transcription factors, thereby leading to an inhibition of cellular proliferation in various cancers.

Outcome Measures
Primary Outcome Measures
- Maximum Tolerated Dose (MTD) of intermittent selumetinib [Up to 2 years]
MTD is defined as the dose associated with a target probability of dose limiting toxicity (DLT) of 25%. DLT will be assessed over the course of first two cycles of treatment (i.e., 8 weeks) for dose selection for subsequent patient treatment initiation.
Secondary Outcome Measures
- Number of adverse events (AEs) [Up to 2 years]
Number of AE throughout the study to assess the safety and tolerability of intermittent selumetinib
- Number of serious adverse events (SAEs) [Up to 2 years]
Number of SAE throughout the study to assess the safety and tolerability of intermittent selumetinib
- Number of subjects with Dose Limiting Toxicity (DLT) [Up to 2 years]
Number of subjects with DLT throughout the study to assess the safety and tolerability of intermittent selumetinib
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Histopathologically confirmed diagnosis of metastatic or unresectable uveal melanoma. Note - Documentation of mutation status for uveal melanoma will not be required prospectively given the high rate of GNAQ/11 mutations (>90%) in this population
-
Able to provide informed consent prior to initiation of study
-
Age ≥ 18 years old
-
Measurable indicator lesion by RECIST v1.1
-
Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as ≥20 mm with conventional techniques or as ≥10 mm with spiral CT scan, MRI, or calipers by clinical exam.
-
Karnofsky Performance Status ≥ 60% or Eastern Cooperative Oncology Group (ECOG) ≤2
-
Ability to take oral medications
-
All clinically significant toxicities from prior therapy must be ≤ grade 1 (with the exception of alopecia)
-
Organ and marrow function and laboratory values as follows:
-
Adequate marrow function
-
absolute neutrophil count (ANC) >1500 cells/mm3
-
platelet count >100,000/mm3
-
hemoglobin >9.0g/dL
-
Adequate hepatic function
-
Angiotensin Sensitivity Test/alternative (AST/ALT)<2.5x upper limit of normal if no documented liver disease or <5x upper limit of normal if documented liver disease
-

-
Negative pregnancy test (serum or urine) for women of child bearing potential
-
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 4 weeks after study discontinuation. 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. 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 lower limit of normal (LLN) for MUGA

-
Acute coronary syndrome within 6 months prior to starting treatment
-
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.
