The cued recall scores ranged from 0-11 and multiple choice recognition scores ranged from 0-12. Change from baseline scores were measured where a positive change from baseline indicates an improvement in verbal recall and memory. | Baseline and Week 24 | |
Primary | Change From Baseline in Rey Complex Figure (RCF) Test Scores | The Rey Complex Figure Test (RCFT) assesses visuospatial construction ability and visual memory through four different tests: copy (copying a complex geometric figure), immediate recall of the figure (drawing figure from memory at 3 minutes), delayed recall (drawing figure at 30 minutes after initial copy), and recognition score (selecting individual parts of the figure from sketches provided). Copy performances are divided into 18 components with a maximum score of 2 each. The maximum score for each figure is 36. | Baseline and Week 24 | |
Primary | Change From Baseline in Letter-Number Sequencing (LNS) Test Scores | The LNS test from the Welchsler Adult Intelligence Scale-III was used to assess working memory. The test required that participants recall, in order, numbers and letters presented in an unordered sequence. The number of items is 21. With each item being marked 0 if reported incorrectly or 1 if reported correctly, the maximum score is 21. Raw scores were converted into T-scores using available normative data. Change from baseline T-scores were measured where a positive change from baseline indicates improvement in performance. | Baseline and Week 24 | |
Primary | Change From Baseline in Trail Making Test (TMT) Scores | The TMT assesses executive function, sequencing, mental flexibility, visual spanning speed and motor function. In TMT Part A, the participant had to draw lines in the correct order between 25 numbers randomly arranged on the page. In TMT Part B, the participant had to draw lines between 25 numbers and letters in alternating order (e.g., 1-A-2-B...etc). Times for Part A and Part B were used to derive T-scores which can range from a minimum of 0 and a maximum of 100. Raw scores were converted into T-scores using available normative data. Change from baseline T-scores were measured where a positive change from baseline indicates improvement in performance. | Baseline and Week 24 | |
Primary | Change From Baseline in the Stroop Color Word Test Scores | The Stroop Color Word Test measures selective attention and cognitive flexibility. The test has three parts, the Word test (reading words), the Color test (naming the ink color in which words are displayed) and the Color-Word test (saying the ink color not reading the word). An interference score was calculated from the Color, Word and Color-Word scores and is an indication of how well a person can complete a task while disregarding interfering information. Raw scores were converted into T-scores using available normative data. Scores range from 0 to 100. Change from baseline T-scores were measured where a positive change from baseline indicates improvement in performance. | Baseline and Week 24 | |

Primary | Change From Baseline in Gastrointestinal Symptom Rating Scale for Irritable Bowel Syndrome (GSRS-IBS) Questionnaire Scores | The GSRS-IBS has 13 questions aimed at identifying the frequency and intensity of IBS symptoms during the past week. Answers are given a score from 1 (no discomfort at all) to 7 (very severe discomfort). A total score was calculated and ranged from 0 to 78. A lower score indicates less discomfort from IBS symptoms. Change from baseline scores were measured where a positive change from baseline indicates increased discomfort from IBS symptoms. | Baseline and Week 24 | |
Primary | Change From Baseline in Swallowing Disturbance Questionnaire (SDQ) Scores | The SDQ had 15 questions relating to the oral phase and pharyngeal phase of swallowing. Answers for 14 questions were assigned a number (0-3) based on a 4-point verbal scale (never, seldom, frequently, very frequently) and the last question was a yes or no question about respiratory infections. A higher score is indicative of greater swallowing issues with 44.5 as the highest possible score. A total score of = 11 suggests impairment. Change from baseline scores were measured where a positive change from baseline indicates increased swallowing impairment. | Baseline and Week 24 | |
Primary | Change From Baseline in Short Form (36) (SF-36) Questionnaire Scores | The SF-36 is a 36-item questionnaire that evaluates quality of life through physical and mental health across eight scales, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability. Change from baseline scores were measured where a positive change from baseline indicates an improvement in quality of life. | Baseline and Week 24 | |
Primary | Change From Baseline in Brief Pain Inventory (BPI) Questionnaire - Severity Scores | The BPI contains 15 questions that assess the severity of pain and its impact or interference on functions of daily life. Pain severity was measured as the mean of 7 items of the questionnaire on an 11-point scale where 0 indicates no pain and 10 indicates the worst pain. A higher score indicates greater pain. Categories assessed include worst pain in 24 hours and average pain. Change from baseline scores were measured where a positive change from baseline indicates a worsening in pain. | Baseline and Week 24 | |
Primary | Change From Baseline in Brief Pain Inventory (BPI) Questionnaire - Interference Scores | The BPI contains 15 questions that assess the severity of pain and its impact or interference on functions of daily life. Pain interference is measured as the mean of 7 items on an 11-point scale where 0 indicates no interference and 10 indicates complete interference. A higher score indicates greater impairment due to pain. Change from baseline scores were measured where a positive change from baseline indicates a worsening of interference due to pain. | Baseline and Week 24 |
