A clinical study brief is a one or two page summary of what you want a human study to show and how it could be done. Health and wellness brands and ingredient manufacturers can use it to line up their own team, then hand it to any research partner as a starting point for a protocol.
This page walks through each section of the brief, and shows one clearly labeled hypothetical sleep-study example.
The short answer
- Start with the question, not the claim. Write the one thing you want to learn about your product in plain language.
- Define who, what, and against what. Population, primary outcome, and comparator shape almost every other choice.
- Pick measurements that fit the outcome. Wearables such as Oura and validated questionnaires measure different things; many studies use both.
- List budget factors early. Sample size, duration, devices, and lab work are among the biggest drivers of scope.
- Agree on ownership and publication up front. Who owns the data and whether results are published regardless of outcome should be in writing before enrollment.
Bring your brief, leave with a study plan
Share your product, your question, and your timeline. We’ll help turn the brief into a study design.
1. Product
Describe exactly what will be studied: the formulation, dose, serving form, and how and when it is taken. If the product may change before launch, note which version the study will use. A study can only speak to the product that was tested.
2. Research question
Write one primary question in a single sentence, for example “Does daily use of Product X change self-reported sleep quality over four weeks in adults with occasional sleeplessness?” Secondary questions are useful, but keep them few. Not every study is designed to support a marketing claim; some are built to learn whether an effect is worth testing further. Our guide to structure/function claims and evidence explains how claim language and study design relate.
3. Population
Who should take part? List age range, the trait or concern that makes someone eligible, and who should be excluded for safety or to keep the data clean. In supplement and wellness research, eligibility usually describes a healthy population with a specific concern. Studies that aim to treat or diagnose a disease fall under different FDA rules and may require an investigational new drug (IND) application.
4. Outcome
Name one primary outcome that answers the research question, plus any secondary outcomes. Say how each is measured and when. A primary outcome chosen before the study starts, and written into the analysis plan, is a key part of what makes results credible.
5. Comparator
What will results be compared against? Options include a placebo, an existing product, the participant’s own baseline, or no comparator in an open-label design. A single-arm pilot is faster and simpler, but it cannot separate the product’s effect from expectation or time. Read should I run a pilot first? for when that tradeoff makes sense.
6. Measurements
- Wearables. Devices such as Oura rings can capture sleep timing, duration, and heart rate data passively at home. Check that the device actually measures your outcome and that participants will wear it consistently. See wearable tech in health research.
- Questionnaires. Validated instruments capture how people feel, which a device cannot. Use established questionnaires where they exist rather than writing new ones.
- Lab measures. If biomarkers matter, note which ones and when samples are collected. Ask whether samples will be processed in CLIA-certified labs.
- Adherence and safety. Plan how product use and any adverse events will be tracked.
Remote collection is one reason many wellness studies run decentralized. Compare the approaches in centralized vs decentralized clinical trials.
7. Budget considerations
You don’t need a number in the brief, but listing the factors helps a partner scope accurately:
- Number of participants and number of study arms
- Study length and number of check-ins
- Devices to buy or ship, and whether participants keep them
- Lab tests, kits, and shipping
- Product supply, including placebo manufacturing if needed
- Ethics (IRB) review and registration
- Participant compensation
- Analysis depth and the type of report or manuscript you want
8. Deliverables
List what you expect at the end: a summary report, a full statistical report, the de-identified dataset, a manuscript draft for peer review, or registration on ClinicalTrials.gov. Be specific about format and who reviews what.
9. Timeline, ownership, and publication
- Timeline. Note any hard dates, such as a launch, and work backward. Allow time for ethics review, recruitment, the study period, and analysis.
- Ownership. State who owns the data and results, and who can access the raw dataset.
- Publication. Decide whether results will be published whatever they show, who is listed as author, and who approves the final text. Agreeing on this before the study starts protects credibility.
Ingredient manufacturers often have extra questions about licensing data to customers; see clinical studies for ingredient manufacturers.
HYPOTHETICAL EXAMPLE: not a real product, client, or study
This filled-in brief is invented to show how the sections fit together.
| Product | “Product X,” a hypothetical nightly sleep-support capsule, one capsule 30 minutes before bed. |
| Research question | Is nightly use of Product X for four weeks associated with a change in self-reported sleep quality in adults with occasional sleeplessness? |
| Population | Healthy adults 25 to 60 who report occasional trouble sleeping; excludes people who are pregnant, take sleep medication, or work night shifts. |
| Primary outcome | Change from baseline in a validated sleep-quality questionnaire score at week 4. |
| Comparator | Pilot: each participant’s own baseline (open-label). Follow-up: placebo-controlled trial if the pilot is promising. |
| Measurements | Oura ring for sleep duration and timing; weekly questionnaires; daily adherence check-in. |
| Budget factors | Participant count, ring supply, four-week duration, IRB review, compensation, summary report. |
| Deliverables | Summary report, de-identified dataset, decision on whether to run a controlled trial. |
| Ownership and publication | Brand owns the data; results registered and shared publicly regardless of outcome. |
A published example of a pilot
For a real, published look at this kind of design, see the phytomelatonin case study. It was a 28-day decentralized, open-label pilot that enrolled 35 healthy adults, with the 22 who completed the study analyzed, using Oura data plus questionnaires.

We’ll review it with you and outline a study design that fits your question.
Frequently asked questions
What is a clinical study brief?
A short document that summarizes the product, research question, population, outcome, comparator, measurements, budget factors, and deliverables for a planned human study. It is a starting point for a protocol, not a protocol itself.
Do I need a finished brief before talking to a research partner?
No. A partial brief is useful. Blank sections show where design help is needed.
Will a study based on this brief support a marketing claim?
Not necessarily. Some studies are designed to support claims and others to learn whether an effect is worth testing further. Results depend on the design and the data.
Can wearables like Oura be used as study outcomes?
They can measure some sleep and activity outcomes at home. Whether they fit depends on the outcome you choose; many studies pair them with validated questionnaires.
