Mean A, B CXCR5-positive B and C, D cTfh cell counts in the single ascending dose and multiple ascending dose cohorts (PD analysis population). The PD analysis population included all patients who received at least one dose of the study treatment and had at least one PD measurement. A single IV dose was administered in SAD cohorts (designated Day 1), and multiple SC doses were administered in MAD cohorts (Day 1 and 29); the study duration including follow-up was 4–10 months from the screening. The plots presented are semi-logarithmic. cTfh circulating follicular T helper-like, CXCR5 C-X-C chemokine receptor type 5, IV intravenous, MAD multiple ascending dose, PD pharmacodynamic, SAD single ascending dose, SC subcutaneous
