Comparing the Digestion of Milk With Different Beta-casein Protein Content by Dairy Intolerant Persons
NCT03713346 · View on ClinicalTrials.gov ↗
Study Summary
Persons with dairy intolerance may experience cramps/abdominal pain, bloating, flatulence, acute diarrhea, or fecal urgency when they ingest excessive amounts of lactose. The intensity of these conditions can be mild or severe and likely depends on numerous variables including dose, transit time, intestinal residual lactase activity and microbiome potential to ferment lactose. Jersey cattle produce milk containing high levels of the A2 β-casein protein . There are claims that high A2 β-casein milk is more easily digested by people who are lactose maldigesters . We propose to conduct a double-blinded, randomized, controlled trial to determine if high A2 β-casein milk from Jersey cattle is actually better digested and tolerated by lactose maldigesters.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03713346
The ClinicalTrials.gov registry entry for NCT03713346 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 42 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Purdue University, which has 100 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Dairy Intolerance appearing as the primary indexed condition, and to 4 interventions — of which Lactose free milk is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT03713346 reports 1 study location spanning 1 distinct geographic area — top geographies include Indiana. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
