Primary Outcome Measures:
  • Frequency of correct predictions [ Time Frame: Assessed 30 days after enrollment, comparing values of phenotypes of interest in the final week of the intervention to the value at enrollment and determining if the actual response is consistent with the prediction made prior to enrollment ]
    Each site of interest is being evaluated for its ability to make correct predictions about subject response. This frequency will be compared via a variety of statistical techniques to that expected by chance to establish its clinical utility.


Secondary Outcome Measures:
  • Genotype-independent effects of substances of interest [ Time Frame: Assessed 30 days after enrollment, comparing value at enrollment to value after in the final week of participation ]
    Baseline responses to environmental factors studied in terms of phenotypes of interest are measured to remove this potential bias from the analysis of predictive power.

  • Change in body mass index [ Time Frame: Assessed 30 days after enrollment, comparing value at enrollment to value after 30 days of participation ]
  • Change in headache severity [ Time Frame: Assessed 30 days after enrollment, comparing value at enrollment to value after in the final week of participation ]
  • Change in headache frequency [ Time Frame: Assessed 30 days after enrollment, comparing value at enrollment to value after in the final week of participation ]
  • Change in rhinitis severity [ Time Frame: Assessed 30 days after enrollment, comparing value at enrollment to value after in the final week of participation ]
  • Change in rhinitis frequency [ Time Frame: Assessed 30 days after enrollment, comparing value at enrollment to value after in the final week of participation ]
  • Change in insomnia frequency [ Time Frame: Assessed 30 days after enrollment, comparing value at enrollment to value after in the final week of participation ]
  • Change in insomnia severity [ Time Frame: Assessed 30 days after enrollment, comparing value at enrollment to value after in the final week of participation ]
  • Change in joint pain severity [ Time Frame: Assessed 30 days after enrollment, comparing value at enrollment to value after in the final week of participation ]
  • Change in joint pain frequency [ Time Frame: Assessed 30 days after enrollment, comparing value at enrollment to value after in the final week of participation ]
  • "Question of the day" questionnaire [ Time Frame: Daily for the duration of participation (2 to 6 months), starting on the day of enrollment and ending when the intervention is concluded, either because the scientific endpoints are met or the subjects voluntarily halt participation.. ]
    Asynchronous longitudinal observations about subject health, diet, environment, lifestyle and anecdotal observations to be used to guide future studies, control for co-linear changes in behavior, monitor for serendipitous events and assess environment-environment interactions. Subjects are asked to answer one question from the survey per day, and questions are asked recurrently at question-specific intervals.

Detailed Description:

The study is composed of multiple interventions which will last between 2 and 6 months that evaluate a suite of predictions about the way that a given environmental factor impacts a specific health outcome based on genetic information obtained from direct-to-consumer genotyping providers (AncestryDNA and 23andMe). Substances of interest include foods, nutritional supplements and non-invasive medical devices.

A minimum of 500 subjects will be enrolled in each intervention, and only those subjects which are predicted to benefit from the intervention when considering all sites of interest will be assigned to an intervention. The predictions are based on hundreds to thousands of sites of interest at high minor allele frequency single nucleotide polymorphisms and predictions about response are derived from the aggregate genotype at all loci considered. As such each site of interest will have a built-in negative control group composed of individuals enrolled in the intervention despite a genotype at that site that does not predict a benefit. The rate that each site of interest makes correct predictions about subject response will be compared to randomly-selected sites in order to quantify placebo effects and establish quality metrics for the predictions.

Enrollment and participation are conducted remotely. Participants will upload genetic information from a direct-to-consumer provider through a mobile or web browser application, and informed consent and inclusion/exclusion criteria are accomplished remotely. After the informed consent process, participants are asked what phenotype of interest (weight, migraines, insomnia, etc.) they are interested in studying, their genetic information is evaluated and they are allowed to select an intervention they qualify for based on their genetics that they would like to participate in. Participants then answer a series of questions to establish baseline data on relevant factors as well as evaluate the inclusion and exclusion criteria; participants that qualify for the intervention are then given specific instructions on how to participate, and may then use the software to report data during the intervention. Each intervention utilizes a specific product rather than a general class of product to reduce noise from differing sourcing, distribution, storage and manufacturing practices.
