The purpose of this study is to investigate how recombinant human lactoferrin (rhLF) which is a partially iron saturated form of lactoferrin produced and purified from rice grain may improve mobility and memory in older adults with chronic inflammation. Lactoferrin, is a known multifunctional protein, and has been shown to have anti-inflammatory effects. A recombinant human version of this protein was recently developed and produced from rice. This is now available from the Ventria Bioscience Company in a controlled, pharmaceutical grade capsule. As part of this double blinded and randomized study, participants will take daily dosages of recombinant human lactoferrin (rhLF) or its matched placebo; to measure the effects of rhlactoferrin on chronic inflammation and its association with improving mobility and memory over a 6 month time period. During the study all participants will be asked to provide blood samples and will have physical and cognitive tests administered to them. By measuring biomarkers in the blood as well as changes in physical and cognitive measures, the investigators will gain an understanding of how rhlactoferrin may safely improve measures of chronic inflammation in older adults. As well as a better understanding of whether it has the potential to meaningfully influence important measures of physical and cognitive function known to be influenced by Chronic Inflammation (CI).

Primary | The Effect of Rhlactoferrin on Serum Levels of Interleukin-6 (IL-6) | The effect of rhlactoferrin on serum levels (picogram/milliliter) of Interleukin-6 (IL-6) will be assessed as a measure of the percentage change of IL-6 serum levels from baseline | Baseline and 6 months | |
Primary | The Effect of Rhlactoferrin on Serum Levels of Tumor Necrosis Factor Alpha Receptor 1 (TNFR1) | The effect of rhlactoferrin on serum levels (picogram/milliliter) of tumor necrosis factor alpha receptor 1 (TNFR1) assessed as a measure of the percentage change of serum TNFR1 levels from baseline | From baseline to 6 months | |
Secondary | Attenuating Cognitive Decline as Measured by the Digital Symbol Substitution Test | The test taker is given a key consisting of numbers 1-9 that are paired with a unique symbol. The test taker is allowed 90 seconds to assign the correct symbol to the number on the list. The test administrator then scores the number of correct answers over the 90 second test time, and assigns a total score based on one point for each correct answer and therefore a higher score is a better outcome. | At 6 months | |
Secondary | Attenuating Cognitive Decline as Measured by the Trail Making Test A and B. | For test A, the test taker is given a sheet of paper that has the numbers 1-25 within individual circles randomly distributed on the page. The test taker is asked to connect the numbers sequentially over a period of 4 minutes (240 seconds). The score is recorded as the time it takes to complete the task in seconds. For test B, the test taker is given a piece of paper that has numbers 1-13 and letters A-L. Each letter or number is inside of a circle. The test taker must then draw a line from one circled number to the next circled letter (ie. 1 to A to 2 to B to 3 to C etc.) over a period of 6 minutes (360 seconds). The time it takes to complete this task is recorded in seconds. | At 6 months | |
Secondary | Physical Mobility as Measured by 4 Meter Walk Test | A standard measurement of 4 meters is marked on a flat, long floor surface. The test taker is asked to walk the length at their usual pace while the test giver is recording the time with a stop watch. This test is repeated twice, and the average of the two recorded times is used as the data point. | At 6 months | |
Secondary | Physical Mobility as Measured by 6 Minute Walk Test | A measured course is set up in an open area on a hard flat surface. The test taker walks on this measured course for 6 minutes, and the test administrators calculates the distance traveled over 6 minutes. The test taker is allowed to rest as is needed. | At 6 months | |
Secondary | Tolerability of Oral rhLactoferrin as Assessed by Patient Diary of Total Number of Side Effects | Study coordinators administered side effect questionnaire at each visit and via phone every two weeks during the treatment period. | From baseline through 6 months. | |
Secondary | Physical Strength as Measured by Grip Strength | Hand grip strength is measured by the amount of static force that the hand can squeeze around a dynamometer. An administrator recorded the reading on the device. The force was measured in kilograms. | At 6 months |
