Comment: Reltecimod is a mimetic peptide that prevents binding of bacterial superantigens to the host target of CD28 [1]. It entered clinical development as an immunomodulating agent, with the aim of reducing the acute inflammatory response observed in patients with necrotizing soft tissue infections (NSTIs) that can lead to organ failure [2-3].
