Conditions
Summary
This prospective, single center, single-arm study aims to evaluate the efficacy and safety of anti-human T lymphocyte porcine immunoglobulin (p-ALG) in combination with cyclosporine and Romiplostim in treating severe aplastic anemia (SAA). It will include 48 patients with newly diagnosed SAA.

Interventions
Romiplostim N01 is a class of TPO receptor agonists. Its TPO peptide can bind to TPO receptors on megakaryocyte precursors in the bone marrow and activate them, triggering a series of intracellular signalling pathways, including JAK2/STAT5, PI3K/Akt, MEK/ERK, and p38, which ultimately lead to gene transcription and increased megakaryocyte proliferation and differentiation.
