Mechanism of action

Methoxsalen is a psoralen that becomes activated when exposed to UVA light, generating reactive oxygen species that damage DNA and trigger cell death. In ECP, patient blood is treated extracorporeally with methoxsalen and UVA exposure, then reinfused, allowing selective destruction of pathogenic T cells while modulating immune responses. This combination is used primarily in cutaneous T-cell lymphomas where circulating malignant cells can be targeted.
