CM-101 is a humanized monoclonal antibody that neutralizes CCL24 to attenuate inflammation and fibrosis in preclinical models. Here we report the results from two Phase 1a studies investigating the safety and tolerability of intravenous (IV) and subcutaneous (SC) CM-101 in healthy participants, and in one Phase 1b study of IV and SC CM-101 in patients with MASLD without evidence of MASH.</p><p><strong>Methods: </strong>In each dose group (0.75 mg/kg, 2.5 mg/kg, 5.0 mg/kg, and 10.0 mg/kg) of the single-center, double-blind, placebo-controlled Phase 1a IV study, healthy volunteers were randomized 3:1 to receive a single IV infusion of CM-101 or placebo.

To achieve this, training, including short-term training (STT) activities, at various levels is required. This article aims to describe the experiences of the authors during the development and implementation of STT in an attempt to improve the PV training landscape of these countries. To identify gaps, a baseline assessment of PV teaching and practices at the national medicines regulatory authorities (NMRAs) and medical universities was conducted. Five successive training sessions, tailored to each country's specific needs and regulatory environments, were conducted; three focusing on fundamental concepts in PV and two dedicated to training-of-trainers courses. The training targeted staff from PV units of the NMRAs and medical universities. Enabling participation from all four countries in the same training fostered cross-country learning and collaboration. The contribution of STT to university education and the operational methodologies within NMRAs are explored, showcasing the impact on knowledge transfer and skill development in each country. In conclusion, by investing strategically in STT activities and fostering partnerships with academic institutions and NMRAs, we demonstrated a sustainable approach to PV capacity strengthening in resource-limited settings.
