Safety Evaluation of THC-Free Hemp Protein Isolate

Not Applicable

Active, not recruiting

• Conditions: Tolerability of Hemp Protein

• Registration Number: NCT07022275
• Lead Sponsor: National University of Natural Medicine

Brief Summary

The goal of this clinical trial is to evaluate the safety and tolerability of a THC-free hemp protein supplement in healthy adult volunteers aged 18-65 years who do not use cannabis or hemp-derived products. The main questions this study aims to answer are:

Does twice-daily consumption of 20 grams of Agoge Hemp Protein Powder for 30 days result in detectable levels of THC-COOH, the primary metabolite of THC, in urine samples? Is the supplement well tolerated, and does it affect common clinical safety markers (e.g., liver and kidney function, inflammatory markers)?

This is a single-arm study with no comparison group. All participants will:

* Consume 20 grams of the hemp protein supplement twice daily for 30 days

* Provide blood and urine samples at baseline and Day 30

* Complete weekly surveys assessing adherence, tolerability, and adverse events

Primary Outcome Measures

Name	Time	Method
Presence of THC-COOH in Urine	30 days	To determine whether THC-COOH, the primary metabolite of THC, is detectable in participants' urine after 30 days of consuming 40 grams of Agoge Hemp Protein Powder.

Secondary Outcome Measures

Name	Time	Method
Number of participants who develop ≥ 1 new clinically-significant laboratory abnormality (hematology, hepatic, or renal) between baseline and day 30.	Baseline (Day 0) and End of Study (Day 30)	A 'clinically-significant laboratory abnormality' is defined as any value judged by the principal investigator to be new-onset or ≥ 1 severity grade and rated as at least 'possibly related' to the study product, using CTCAE v5.0 grading where available. CBC - hemoglobin, hematocrit, WBC, or platelet count that shifts from normal at baseline to below/above reference limits by ≥ 1 CTCAE grade. Hepatic Panel - AST or ALT rises to \> 2 x upper limit of normal (ULN). Renal Panel - estimated glomerular filtration rate (eGFR) falls to \< 60 mL/min/1.73 m\^2 or decreases by ≥ 25% from baseline; blood-urea-nitrogen-to-creatinine ratio (BUN:Cr) rises above 20:1 if previously normal. Venous blood is drawn at day 0 and day 30 for CBC, CMP, and calculated eGFR. Results are entered into REDCap, reviewed by a clinician, and coded for relatedness and severity. The study will report n/N (%) of participants meeting any abnormality criterion.
Number of participants who experience ≥ 1 treatment-emergent adverse event related to the product	30 days - Participants complete the REDCap Survey on days 7, 14, 21, and 28	Any self-reported adverse event (AE) deemed at least "possibly related" to the study product. Data collection will occur through a 7-item symptom questionnaire through a REDCap Survey querying about nausea, headache, dizziness, fatigue, skin reactions, gastrointestinal issues, or any other unsolicited symptoms. If any symptom is reported, study staff complete a standardized spontaneous AE reporting form. Each AE is graded for severity (mild, moderate, severe) and relatedness (unrelated, possibly, probably, or definitely) by study staff. The count and proportion of participants experiencing ≥ product-related AE over the 30-day intervention will be reported (n/N \[%\])
