简要总结
The purpose of this study is to examine the safety and influence of an intervention (COGNUTRIN) using nutritional supplements (n-3 fatty acids and blueberry anthocyanins) on cognitive performance in breast cancer survivors following chemotherapy. The investigators' goal is to treat or lessen the late effects of cancer treatment. The supplement to be used will be a combination of the following: (1) VitaBlue (40% polyphenolics, 12.5% anthocyanins from blueberries (BB) and (2) n-3 fatty acids - Lovaza.
详细描述
This pilot study will evaluate the feasibility of administration of the nutritional supplement and placebo in this patient population and performing cognitive function testing at baseline and post supplementation.
This is a randomized, double-blind pilot study of COGNUTRIN vs. Placebo.
Participants have an equal chance (like flipping a coin) of being in either of the study groups. Neither the participant nor the study doctor will be able to choose which study group the participant is in. Participants will not know and the study doctor will not know which study group the participants are in.

- •Able to understand and sign the informed consent
- •Fluent in reading, comprehension and communication in the English language
- •No evidence of dementia - Mini Mental State Examination (MMSE) >=23 but some evidence of cognitive impairment
- •Must be aware of the nature of his current medical condition and must be willing to give consent after being informed of the experimental nature of therapy, alternatives, potential benefits, side-effects, risks and discomforts
- •Eastern Cooperative Oncology Group (ECOG) performance status of 0- 2 (Karnofsky score >60%)
- •Acceptable hemoglobin and hematocrit level based on complete blood count (CBC)
- •Must be willing to be monitored for adequacy of nutritional intake during the intervention, as is the current standard of clinical practice
排除标准
- •Use of estrogens (oral, dermal or vaginal), progesterone (oral or topical), androgens, Raloxifene or Tamoxifen during the previous 3 months
- •Use of over the counter steroid hormonal supplements including dehydroepiandrosterone (DHEA)
- •Patients with advanced or Stage IIIIB or IV breast cancer or other cancers
- •Use of n-3 fatty acids or high dose antioxidant supplements other than what is provided in the trial
- •History of known allergy to components of the study supplements
- •Renal or liver disease
- •Concurrent participation in another chemoprevention trial
- •Evidence of bleeding diathesis or coagulopathy
- •Metabolic abnormalities (e.g. thyroid disorders, insulin dependent diabetes, rheumatologic disease etc.)
- •Known claustrophobia, presence of pacemaker and/or ferromagnetic material in their body that would prohibit MRI imaging
- •Medical history of concussions
- •Other acute or chronic medical or psychiatric condition or laboratory abnormality that may increase risk associated with study participation or study drug administration, or may interfere with interpretation of study results, and in the judgment of the investigator would make the potential participant inappropriate for entry into this study

结局指标
主要结局
Change in Cognitive Function Scores With Intervention - Color Trails 1 & 2
时间窗: Baseline (Time 1) and at 3 months +/- 7 days (Time 2)
Mean change in cognitive function scores measured from baseline to post intervention with Cognutrin compared to placebo arms of the trial. Mean cognitive function scores by group and compared by time of testing (Time 1, Time 2). Tests: Color Trails 1 \& Color Trails 2. Color Trails 1 consists of a page with scattered circles numbered from 1-25. Even numbered circles are colored yellow and odd numbered ones are colored pink. Respondents are instructed to connect the circles in consecutive numeric order with a continuous line as quickly as possible. Score is determined by recording the number of seconds required to complete the task. Color Trails 2 consists of a page containing 25 pink circles and 25 yellow circles numbered 1-60. Respondents are instructed to connect circles in consecutive order while alternating colors. A total score is determined by recording the number of seconds required to compete the task.
Change in Cognitive Function Scores With Intervention - HVLT and COWA
时间窗: Baseline (Time 1) and at 3 months +/- 7 days (Time 2)
Mean change in cognitive function scores measured from baseline to post intervention with Cognutrin compared to placebo. Mean cognitive function scores by group and compared by time of testing (Time 1, Time 2). The HVLT test assesses verbal learning and memory. Subjects are given a list of words and asked to repeat as many words as they can recall at 3 times. There is no absolute low \& high, as scores are age adjusted. Reported scores are T-scores- average score should be 50, with a standard deviation of 10. Any score below 50 indicates performance below population averages and any score above 50 indicates higher than population averages.The COWA test is a verbal fluency test that measures spontaneous production of words belonging to the same category or beginning with a designed letter. The scores are converted to z-scores. A Z score of -1 is 1 standard deviation below mean. The lowest and highest Z scores could be ≤ -3.0 and ≥3.0. A lower Z score is indicative of poor fluency.
Change in Cognitive Function Scores With Intervention - Symbol Digit Modalities Test
时间窗: Baseline (Time 1) and at 3 months +/- 7 days (Time 2)
Mean change in cognitive function scores measured from baseline to post intervention with Cognutrin compared to placebo arms of the trial. Mean cognitive function scores by group and compared by time of testing (Time 1, Time 2). The Symbol Digit Modalities Test requires respondents to write the number that corresponds with each symbol for a series of 110 items in which the symbol but not the number appears. Respondents identify the correct number using a key provided in which symbols are matched with numbers. Total score is determined by calculating the number of items correctly completed in 90 seconds Scale uses z-scores which have a mean of 0 and a standard deviation of 1. Scores cores above 0 indicate better than average performance whereas scores below 0 indicate poorer than average performance.
Change in Cognitive Function Scores With Intervention - Digit Span
时间窗: Baseline (Time 1) and at 3 months +/- 7 days (Time 2)
Mean change in cognitive function scores measured from baseline to post intervention with Cognutrin compared to placebo. Mean cognitive function scores by group and compared by time of testing (Time 1, Time 2). The Digit Span assesses immediate verbal memory and auditory attention. The examiner reads increasingly longer series of numbers and the respondent is required to repeat them in the same order. The examiner then reads additional sequences of numbers and the respondent is required to repeat them in reverse order. Digit Span yields one score, number of items completed correctly. Scores are scaled from the Wechsler Adult Intelligence Scale. The values for these scaled scores indicated that values from 1-7 indicate below average performance, corresponding to 1-16 percentile ranks. Scores between 8-12 indicate average performance, corresponding to percentile ranks of 25-75. Scores between 13-19 correspond to areas of strength and 84-99 percentile ranks.
