Immune Defense Protein Impact On Respiratory Immune Outcomes

The primary goal of this study is to observe the impact of the IDP® Supplement on the duration and severity of upper respiratory symptoms in older individuals during the cold and flu season. Secondary aims include observing the product's effect on rescue medication use, quality of life, and overall tolerability. This is conducted as a consumer-driven, decentralized observational clinical research study in adults aged 60 or older, using self-reported measures and questionnaires completed at home via the Chloe App.

About this study

The rationale for this study is to observe the impact of IDP® Supplement on upper respiratory tract symptoms, including duration and severity, in older individuals during the cold and flu season. Additionally, the study aims to observe the impact of the product on the type and frequency of use of rescue medication(s), the impact on individuals' activities and quality of life, and the overall tolerability of the study product. These endpoints will be assessed via activities and technologies that can successfully and effectively be completed in a home setting. A consumer-driven, decentralized observational clinical research study is therefore well-suited for examining the impact of this product in this population.

The investigators will examine the outcomes in adults aged 60 years or older who have chosen to try this product. The study will incorporate participant reported outcome questionnaires and surveys. There is no "doctor-patient" relationship as part of this research since the participant as a consumer is making the informed choice to take the product and take part in the observational process with self-reported measures and questionnaires completed at-home using the Chloe App. Findings from this study will contribute knowledge toward the tolerability, formulation, and design of future studies.

Primary outcomes

  1. Impact on Upper Respiratory Symptom Incidence, Duration and Severity

    Time frame: 17 weeks

    To evaluate the impact of IDP® Preventative Supplementation on incidence of upper respiratory symptoms, and the duration and severity of any symptoms that occur by measuring the change in incidence of upper respiratory symptoms (frequency, type, duration and severity) between study product and placebo groups. Baseline will be compared as well.

Secondary outcomes

  1. Impact of IDP on Upper Respiratory Symptoms

    Time frame: 17 weeks

    To evaluate the impact of IDP® Supplement on Upper Respiratory symptoms by evaluating the change in Wisconsin Upper Respiratory Symptom Survey score ranging from a minimum of 0 (no symptoms) to a maximum of 140 (maximum severity), between product and placebo groups. Baseline will be compared as well.

  2. Impact on Rescue Medications

    Time frame: 17 weeks

    To evaluate the impact of IDP® Supplement on the frequency of use and type of rescue medications by measuring the change in the daily use and type of rescue medications used for Upper Respiratory symptoms between product and placebo groups. Baseline will be compared as well.

  3. Impact on Quality of Life

    Time frame: 17 weeks

    To evaluate the impact of IDP® on quality of life by measuring the change in the 36-Item Short Form Health Survey (SF-36) between product and placebo groups. The raw scores are transformed into a 0-100 scale, where 0 represents the lowest/worst health state and 100 the highest/best health state. Baseline will be compared as well.

  4. Safety and Tolerability Assessment

    Time frame: 16 weeks

    To evaluate the tolerability of IDP® Supplement by assessing the number, frequency, and severity of adverse events (AEs), serious adverse events (SAEs) and AE withdrawals reported over the study product and placebo use period.
