Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Part 1:
SAR444559: Single dose administration of SAR444559 on Day 1, of approximatively 9 single ascending dose levels. The starting dose will be 0.03 mg.

Treatment duration will be 7 weeks, including a 4-day in-house institutionalisation period after single dose administration and a follow-up period up to the end of study (EOS) visit.

Mode of administration: Subcutaneous (SC) injection administered by the clinical study site staff in the clinical study center. The dose increment factors for dose escalation will be based on the observed cell depletion and may be adjusted following emerging safety and tolerability.

Part 2:
SAR444559: Multiple dose administrations of SAR444559 every 2 weeks (Q2W) on days 1, 15, and 29, of up to 3 ascending repeated dose levels.
The starting dose of part 2 will be determined upon review of adverse event, PK and PD data from Part 1 by a safety review committee. The dose increment factors for dose escalation will be based on the observed cell depletion and may be adjusted following emerging safety, tolerability.

Treatment duration will be approximately 11 weeks including 4-day in-house institutionalisation periods after each dose administration (3 total doses) and follow-up periods between and after each of the three institutionalizations up to the end of study (EOS) visit. Mode of administration: SC injections administered by the clinical study site staff in the clinical study centre.

Participants in part 1 and part 2 are recruited independently, and part 2 will be undertaken in unique participant cohorts.

The strategies used to monitor adherence to and/or fidelity of the intervention will include supervised administration at site, appropriate record of each administration information, and double confirmation of the dosing by another member of the study site staff other than the one administrating the study intervention.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomization lists for each study part are generated by Sanofi and will be provided to the unblinded pharmacist. The open randomization list will be filed in a sealed envelope with tamper-proof adhesive tape and stored at the pharmacy. The study interventions will be allocated in accordance with those lists by the unblinded pharmacist. Investigators will remain blinded to each participant’s assigned study intervention throughout the course of the study.
