Effects of Methylphenidate Versus Sustained Release Methylphenidate on Cognitive Functioning

M.D. Anderson Cancer Center34 enrolled

Overview

Primary Objective: * To assess the efficacy of immediate release methylphenidate, sustained release methylphenidate, and the novel vigilance enhancing drug modafinil for the improvement of cognitive functioning in patients with brain tumors.

All three drugs used in this clinical research study are widely used stimulants to help cancer patients who have fatigue and problems with concentration. Before treatment starts, you will have a physical exam, including measurement of blood pressure, and neuropsychological and symptom evaluations. The neuropsychological evaluation is made up of tests of attention, memory, speech, and other brain functions, and takes about 30 minutes to complete. The other test evaluates symptoms you may be experiencing, such as fatigue or depression, and takes about 10 minutes to complete. You will be randomly assigned (as in the toss of a coin) to one of three treatment groups. Participants in the first group will receive Immediate Release (IR) methylphenidate. Participants in the second group will receive Sustained Release (SR) methylphenidate. Participants in the third group will receive modafinil. There is an equal chance of being assigned to any of the groups. After you are randomized, you will contact the M. D. Anderson pharmacy to receive your assigned medication. You will receive a total of 5 weeks worth of medication. The extra week of medication is to allow for buffer should there be any conflict in rescheduling the follow-up evaluation. IR methylphenidate is a pill taken twice a day. Both SR methylphenidate and modafinil are pills taken once a day. The amount of the medicine is the same for all three groups. You will take the medication every day for a total of 4 weeks. You will be asked to complete a study calendar, which will be provided by the research staff. In the study calendar, you will be asked to initial after you take the study drug each day, and to record any side effects you may experience. You will be required to return the completed study calendar at the final evaluation visit, along with the empty bottles and any of the study drugs that may be left over. You will remain on treatment for 4 weeks and return for a final evaluation. A follow-up neuropsychological evaluation and evaluation of symptoms will be performed. At the end of the study treatment period, you will be allowed to remain on active treatment if you wish to. You can discuss with your doctor whether to continue on the same medication or to try another one. This is an investigational study. All of the study drugs are FDA approved and currently are used to help brain tumor patients. A total of 75 patients will take part in this study. All will be enrolled at M. D. Anderson.

Outcomes

Primary Outcomes

Mean Processing Speed Change From Baseline in the Trail-making Test Part A Score

'Trail Making Test Part A' is a neuropsychological test of visual attention and task switching, administered to measure processing speed, timed as participants follow "trail" made by consecutive numbers (1,2,3, etc.). The test is finished as quickly as possible, and the time taken to complete the test used as the primary performance metric (in seconds). Maximum time allowed is 300 seconds. A lower change score indicates improvement. Participants tested before starting study medication and 4-5 weeks later while on study medication, reflected in a z score (deviations from population mean).

Time frame: Baseline to 4-5 weeks on study medication

Patient Cognitive Test Scores at End of Treatment Period

For cognitive assessment, set of widely used standardized psychometric instruments shown to be sensitive to neurotoxic effects of cancer treatment. Measures assess attention span (Digit Span), graphomotor speed (Digit Symbol), memory (Hopkins Verbal Memory Test-Revised), verbal fluency (Controlled Oral Words Association), visual motor scanning speed (Trail Making Test Part A), executive function (Trail Making Test Part B); motor speed and dexterity (Grooved Pegboard).

Time frame: Baseline to end of Week 4 treatment period
