Intervention/exposure

Description of intervention(s) / exposure
Part 1 – Single ascending doses and food-effect: Cohorts 1 to 5
Planned a single oral dose of ALP001E capsules under fasting conditions: 25 mg, 75 mg, 150 mg, 300 mg, 600 mg. Subjects from Cohort 3 will be administered the same dose in a second period after ingestion of a high-fat meal. Subjects will be served a high-fat, high-caloric meal of approximately 800 to 1000 calories (approximately 50% of total caloric content of the meal derived from fat). This test meal should derive approximately 150, 250, and 500-600 calories from protein, carbohydrate, and fat, respectively. An example would be a meal consisting of two eggs fried in butter, 2 slices of toast with butter, 2 strips of bacon, approximately 120 g of hash brown potatoes, and 240 mL of whole milk.

Part 2 – Formulation bridging cohort (if needed)
If needed, one dose level is planned for Part 2 after evaluation of bioavailability and safety data of Cohort 3 of Part 1 as determined by the SRC. In this bridging cohort, dose in suspension will be then repeated using a lower step down dose administered in previous cohort, final dose to be determined by dose escalation committee based on preceding safety and PK data. A single oral dose of ALP001E given by staff in the study unit.

Part 3 – Multiple ascending doses: Healthy Cohort 6 and type 2 diabetes (T2DM) Cohort 7 to 9
Planned dose of ALP001E capsules to healthy volunteers (Cohorts 6): 150 mg
Planned dose of ALP001E capsules to T2DM (Cohorts 7 to 9): 50 mg, 100 mg, and 150 mg
Oral given by staff in the study unit once daily for 14 days.

The strategies of adherence to the doses:
For Part 1, Study medication capsules will be administered to each subject with approximately 240 mL of water. For Part 2 (if needed), suspension formulation will be prepared and orally administered to study subjects. For Part 3, drug administration will be done at the same time every day.
A hand and mouth check will be performed to ensure consumption of the medication to all subjects.

The composition of the placebo hypromellose acetate succinate (92.74%), and macrogol (15)-hydroxystearate (7.26%).
Control group

Outcomes
Primary outcome [1] 325225 0
Safety and tolerability will be assessed by reporting of adverse events (i.e., seriousness, severity, relationship to the study medication, outcome, duration), clinical laboratory tests (hematology, biochemistry), physical examination (System Organ Class examination), vital signs (systolic and diastolic blood pressure: manual sphygmomanometer, digital blood pressure cuff, heart rate (oxymeter), respiratory rate and body temperature: oral or aural) and 12-lead ECGs (semi-supine 12 lead-paper ECG).

As this is the first study of ALP001E in humans, adverse events are not yet known. Based on findings from the nonclinical testing program, and the experience with other GRAs that have undergone clinical testing potential risks include: hepatic steatosis; increases in blood pressure, cholesterol/lipids, weight, and AST/ALT; abnormal storage of glycogen; decreased blood sugars; increased number of alpha cells; and glucagonoma.
Timepoint [1] 325225 0
During Part 1 and 2, subjects will be confined to the study unit and assessed daily from Day -1 to Day 3 before being discharged. Subjects will return for follow up on Day 6 +/- 1. At the end of each dosing cohort a safety review committee will meet to review all available safety information to determine if it is safe to continue to the next dose level.
During Part 3, subjects will be confined to the study unit and assessed daily from Day -1 to Day 6 morning before being discharged. Subjects will return daily to the study unit every day from Day 7 until Day 11 when they will be re-confined again until Day 15. Subjects will be then discharged and will return for a follow up on Day 19 +/- 1.
