Plain English Summary

Background and study aims
The IntelliCap capsule is a swallowable, electronic, capsule-shaped device. It holds a liquid drug payload. The capsule contains sensors (for acidity and temperature), a battery, a microprocessor, a small motor, and electronics for wireless, real-time communication with an external receiver. When swallowed, it travels through the gut with its natural movement and is excreted with a bowel movement. Real-time data from its sensors are used to locate the capsule within the gut. Upon command, the capsule releases its liquid drug payload in a controlled way over time by the action of a small motor. The study aims to explore the levels of this marker drug in blood when released from the IntelliCap capsule in a pre-programmed way over time compared to a marketed drug capsule.

Who can participate?
Adult men who are healthy as determined by an upfront health check, can participate in the study.

What does the study involve?
Participants are asked to swallow one IntelliCap capsule and a marketed drug capsule in a random order with an interval of one week in between. Blood samples are taken over time to find out the levels of the drug. They have to stay at the clinic each time for about 2 days. Additional assessments are made to monitor safety. After completion, participants have to return to the clinic for a final assessment. Those swallowing an IntelliCap capsule have to wear a mobile phone-size device around their waist that communicates between the IntelliCap capsule in the body and a computer. They have to collect their stool and recover the excreted IntelliCap capsule that is then returned to the clinic.

What are the possible benefits and risks of participating?
No particular benefit is expected or intended for participants. Drug-related risks include swelling of ankles, decrease in the blood pressure, slow heartbeat, upset stomach, dizziness, facial flushing, headache, light-headedness, skin irritation (rash), tiredness and weakness. Capsule may get stuck in the bowels or the capsule may come apart and could injure the bowels.

Where is the study run from?
ProMedica Clinical Research Center, Brighton, USA.

When is the study starting and how long is it expected to run for?
Recruitment of healthy volunteers for this study started in December 2011 and the study ended in January 2012.

Who is funding the study?
Medimetrics Personalized Drug Delivery Inc., USA.

Intervention

14 male, healthy volunteers at a single site will undergo both of the following interventions in a randomized order with a wash-out period in between of at least 7 days:

1. IntelliCap capsule: payload diltiazem HCl aqueous solution (270 mg/mL), programmed to dispense 60 mg over 24 hours with a first order release profile
2. Diltiazem Hydrochloride Extended-Release capsules USP (60 mg, Cardizem SR®, Mylan Pharmaceuticals Inc., Morgantown, WV 26505, USA)

Subjects have to stay at the clinical center each time for about 2 days. After completion of the treatments, subjects have to return to the clinical center for a final assessment.

Primary outcome measures

Pharmacokinetics of diltiazem released from the IntelliCap as compared to a marketed extended release capsule (AUClast, AUC0-t, AUC∞, Cmax, Tmax, Tlag, T1/2). Blood collection for diltiazem (parent) bioanalysis: pre-administration, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 16, 24, 36, 48 h post-administration. Diltiazem is determined in plasma by a validated liquid chromatography tandem mass spectrometry (LC-MS/MS) method, lower limit of quantification (LLOQ) at 0.2 ng/mL using 200 μL plasma.

Secondary outcome measures

1. Adverse events, adverse device effects (number, severity)
2. Physical examination: Day -1 in each period, end of study visit (> 4 days after last administration)
3. Vital signs and body measurements: body weight, oral body temperature: Day -1 in each period, end of study visit. Systolic and diastolic blood pressure and pulse rate: Day -1, pre-administration, 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, 36, 48 h post-administration, end of study visit (> 4 days after last administration)
4. ECG evaluation: Day -1 in each period, end of study visit (> 4 days after last administration)
5. Standard clinical laboratory evaluation (hematology: hemoglobin, hematocrit, WBC count with differential (monocytes, eosinophils, basophils, neutrophils, lymphocytes) as absolute value, RBC count and platelet count. Blood chemistry: albumin, alkaline phosphatase, bilirubin (total, direct and indirect), bicarbonate/CO2, calcium, cholesterol, chloride, creatinine, CK, gamma-GT, glucose, LDH, inorganic phosphorus, lipase, amylase, magnesium, potassium, total protein, AST, ALT, sodium, triglycerides, urea/BUN and uric acid. Urinalysis: specific gravity, pH; semi-quantitative 'dipstick' evaluation of glucose, protein, bilirubin, ketones, leukocytes, blood): Day -1 in each period, 24 h post-administration, end of study visit (> 4 days after last administration)
