Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This is a randomized, double-blind, placebo-controlled study of FB102 in healthy participants. Part A is the single ascending dose (SAD) portion, and Part B is the multiple ascending dose (MAD) portion.

Part A: (SAD) Up to 6 groups (Groups A1 to A6) of 8 healthy participants per group.
Group A1: 3 mg/kg Intravenous (IV) dose
Group A2: 7.5 mg/kg IV dose
Group A3: 15 mg/kg IV dose
Group A4: 1 mg/kg Subcutaneous (SC) dose
Group A5: 3 mg/kg SC dose
Group A6: IV or SC dose (TBD) of FB102*
* The SMC will determine the dose for Group A6 based on cumulative review of safety and PK data from prior groups. The dose will not exceed 15 mg/kg.

Part B: (MAD) Up to 4 groups (Groups B1 to B4) of 8 healthy participants. Within each group, participants will receive 4 weekly doses
Group B1: 3 mg/kg IV doses
Group B2: 10 mg/kg IV doses
Group B3: 15 mg/kg IV doses
Group B4: multiple lV or SC doses (TBD)#
#The SMC will determine the dose and route (IV or SC) for Group B4 based on cumulative
review of safety and PK data from prior groups. The dose will not exceed 15 mg/kg.

Adherence to Intervention will be managed via recording in appropriate drug accountability records.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be randomized 3:1 to receive FB102 or placebo. The unblinded CRO biostatistician will prepare the study randomization schedule and treatment assignment list and distribute to the site’s unblinded pharmacy team to be kept in an area with restricted access per institutional guidelines. Emergency unblinding codes will be stored securely by the unblinded pharmacy at the research facility.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomization schedule and corresponding treatment assignment will be generated by the CRO’s biostatistics department per CRO standard operating procedures (SOPs).
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
