Recurrent Plasma Cell Myeloma, Refractory Plasma Cell Myeloma
About this trial
This is an interventional treatment trial for Recurrent Plasma Cell Myeloma
Eligibility Criteria
Inclusion Criteria:

Measurable disease defined as:
- Serum monoclonal protein >= 1 gm/dL or
- Urine monoclonal protein of >= 200 mg/24 hours, or

- Measurable bone disease, defined as >= 1 unidimensionally measurable lesion (longest diameter to be recorded) >= 20 mm with conventional techniques or >= 10 mm with spiral computed tomography (CT) scan (for patients with lytic bone disease)
- Eastern Cooperative Oncology Group (ECOG) performance status =< 2

- Platelets: >= 75,000/μL (independent of blood cell growth factors or transfusion)
- Total bilirubin: =< 1.5 x upper normal limit; however, patients with documented Gilbert's syndrome are eligible
- Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]): < 2.5 x upper limit of normal (ULN)
- Creatinine: < 3.0 x ULN
Known human immunodeficiency virus (HIV) infected patients meeting the following characteristics are eligible:
- Cluster of differentiation (CD)4 cell count >= 500/mm^3
Meeting either of the following:
- Willing to suspend antiretroviral therapy for duration of protocol therapy or
- On stable regimen of combination antiretroviral therapy that does not include either zidovudine or stavudine for at least 12 weeks and without evidence of toxicity
- No HIV-associated condition that defines acquired immunodeficiency syndrome (AIDS)
Prior allogeneic stem cell transplant is allowed provided that all of the following conditions are met:
- >= 6 months have elapsed since allogeneic transplant
- No graft vs. host disease (GVHD) is present
- Not currently on immunosuppressive therapy
- Women of child-bearing potential must agree to use a medically accepted form of contraception prior to, during, and for four weeks following study treatment; men must agree to use a medically accepted form of contraception prior to, during, and for sixteen weeks following study treatment
- Able and willing to provide a written informed consent
- Prior palliative and/or localized radiation therapy is permitted, provided at least 14 days have passed from date of last radiation therapy
- Pulse oximetry of >= 95% on room air
Exclusion Criteria:
Any concurrent condition or planned treatment that would compromise study objectives or represent an unacceptable patient risk, including but not limited to:
- Planned concurrent treatment for multiple myeloma other than bisphosphonates; ongoing corticosteroids for indications other than multiple myeloma allowed as long as the dose does not exceed 60 mg of prednisone per day or equivalent
- Persisting effects of any previous or ongoing treatment that might compromise delivery of study treatment or assessment of adverse events
- Planned concurrent treatment with any other investigational agents
- Cytotoxic chemotherapy less than 2 weeks, or biologic therapy less than 2 weeks, or corticosteroids less than 2 weeks prior to registration
- No other malignancy unless the patient has been disease-free for >= 1 year
- Known multiple myeloma of central nervous system or leptomeninges
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to AZD6244
- Previous mitogen activated protein kinase (MEK) inhibitor use
- Uncontrolled hypertension, i.e., persistent blood pressure (BP) of >= 160/95
- Significant cardiovascular disease (New York Heart Association class II, III or IV cardiac disease), hypertrophic cardiomegaly or restrictive cardiomyopathy, myocardial infarction within the past 6 months, unstable angina, unstable arrhythmia unstable or a need for anti-arrhythmic therapy (use of medication for atrial fibrillation is allowed, if stable for at least 3 months)
- Refractory nausea and vomiting, chronic gastrointestinal diseases (e.g. inflammatory bowel disease), or significant bowel resection that would preclude adequate absorption
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection or psychiatric illness/social situations that would limit compliance with study requirements
- Pregnant or nursing
- Left ventricular ejection fraction (LVEF) =< 45% by echocardiogram (ECHO) or multigated acquisition scan (MUGA) scan
- Any requirement for supplemental oxygen

Experimental
