Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Part A includes up to 8 dosing cohorts with 8 subjects in each cohort. Each subject receives one dose of ALD1910 or placebo infused into a vein. The ALD1910 dose level increases for each cohort (1 mg, 3 mg, 10 mg, 30 mg, 100 mg, 300 mg, or 1000 mg) if data from each cohort show it is safe to do so.
Part B includes 2 dosing cohorts with 16 subjects in each cohort. The dose for Part B will be determined based upon the safety data committee review of all doses tested in part A. In one cohort subjects will receive either ALD1910 or placebo infused into a vein. Subjects will also receive 6 mg sumatriptan injected under the skin 2 hours after the end of the ALD1910 or placebo infused into a vein. In the second cohort subjects receive one dose of ALD1910 or placebo injected under the skin. The ALD1910 dose level is one of the doses tested in Part A and will not exceed 100 mg.
Each subject will remain in the study unit until the morning of the 3rd day after dosing (approximately 48 hours post-dose). Subjects will complete 9 additional outpatient visits for safety assessment over 20 weeks.

Outcomes
Primary outcome [1] 320784 0
Safety (e.g., Adverse Events (AE), Serious Adverse Events (SAE), Vital Signs Measurements, Electrocardiogram (ECG) Results, Clinical Laboratory Results)
Possible AEs/SAEs may include hyperglycemia detected and followed with laboratory tests and clinical examination
Timepoint [1] 320784 0
Baseline, Day 1, 2, 3, 5 and Week 2, 3, 4, 6, 8, 10, 12 and 20 after intervention. All safety assessments are completed at all scheduled visits including screening, except for the following:

Secondary outcome [1] 372839 0
Pharmacokinetics. Single dose ALD1910 pharmacokinetics are derived from the serum concentration versus time profile relative to the start of dose administration for each subject. Parameters (Peak Concentration (Cmax), Time to the observed maximum concentration (tmax), Area under the concentration-time curve, time zero to the last time point (AUC(0-T)), Area under the concentration-time curve, time of dosing (0 hr) extrapolated to infinity (AUC(INF)), Terminal half-life (T1/2), Clearance (Cl), and Volume of distribution based on the terminal elimination phase (Vz).

Secondary outcome [2] 373558 0
Immunogenicity. Development of anti-ALD1910 antibodies (ADA) and characterization of anti-ALD1910 ADA positive responses for neutralizing activity, as determined from serum samples analyzed using validated methods
Timepoint [2] 373558 0

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Once the participant is confirmed eligible, the participant will be randomised on Day 1 by assigning the randomisation number using a randomisation schedule.
The blinded IP will be dispensed for the participant as per randomisation assignment.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer-generated randomization schedule will be prepared to randomly allocate the subjects to treatment groups in the appropriate ratio according to the cohort. Randomization will occur in blocks (block sizes will be undisclosed).
