Walmart opens in-store clinical trial centers to boost access to research

Walmart is bringing clinical trials closer to the shopping trip itself, with new research sites planned near the front of stores in Houston, Tyler and Dalton over the next month. The move is meant to make research feel like part of everyday errands, not a separate medical appointment, and Walmart says the setup is designed to cut the biggest barriers to participation: distance, time, cost and simple lack of awareness.

The new effort, called the Clinical Trial Center by Walmart and Care Access, focuses first on heart and brain health. Walmart said placing the sites near the front of stores is meant to reach people while they are already moving through familiar spaces, which could matter for associates as much as customers. Pharmacy teams, front-end workers and store leaders may see more questions, more health-related traffic and more need to direct people to the right place without disrupting the normal flow of the store.

That operational shift is part of a broader push to make the retailer’s health business feel more integrated. Walmart has long framed health care as a convenience issue, pointing to low-cost medicines, ReliOn insulin and pharmacy services as examples of how it already brings basic care into the store. Its Health & Wellness page says pharmacists are available to answer medication-related questions and help with prescriptions, a model that the clinical-trial locations extend into research access.

The company and Care Access first previewed the plan in January, saying they would open research sites in three former Walmart Health locations and one rural Walmart store in spring 2026. Care Access said those sites would support Phase 2, Phase 3 and Phase 4 clinical studies, bringing research directly to communities that often face the most practical barriers to participating.

Walmart launched the Walmart Healthcare Research Institute in 2022 to expand community access to research, with an early focus on underserved groups including older adults, rural residents, women and minority populations. In that earlier rollout, Walmart’s chief medical officer, Emily Aaronson, said clinical research should feel “practical and approachable,” and Care Access co-founder and CEO Ahmad Namvargolian said the partnership was aimed at improving access to clinical research opportunities and the future of health for all.

For Walmart workers, the significance is less about a headline initiative than about what changes inside the building. The store entrance is becoming more than a place to walk through on the way to aisles and registers. It is now a service zone where shopping, prescriptions and research can overlap in one visit, and where Walmart’s footprint is being used as a health platform for the communities around it.
