How Are Emerging Immune-Targeted Pipelines Changing the Future of HLH Treatment? Ipsoprubart (ELA026) – Electra Therapeutics Ipsoprubart (ELA026) is currently one of the most advanced investigational therapies specifically being developed for secondary HLH. The fully human monoclonal antibody targets SIRPα, SIRPβ1 and SIRPγ, which are expressed on activated myeloid cells and T cells involved in the cytokine storm associated with sHLH. Rather than broadly suppressing the immune system, the therapy is designed to preferentially eliminate disease-driving activated immune cells. Electra is evaluating ipsoprubart in the global SURPASS Phase 2/3 registrational study (NCT05416307) in treatment-naïve adult and pediatric patients with secondary HLH. The study is actively enrolling across the United States and Europe and uses 8-week survival in treatment-naïve lymphoma-associated HLH as its primary efficacy objective. The program has gained additional commercial significance after earlier clinical activity in lymphoma-associated sHLH. Electra reported an objective tumor response rate of 100% among eight lymphoma-associated sHLH patients, including a complete response rate of 88% (7 of 8 patients). In October 2025, Electra also raised USD 183 million in Series C financing, with proceeds earmarked partly for the global pivotal ELA026 program in sHLH. Plonmarlimab – TJ Biopharma Plonmarlimab is another targeted biologic being investigated for rheumatic and immunologic disease-associated HLH/macrophage activation syndrome. TJ Biopharma completed an open-label, multicenter Phase 2 study (NCT07034209) evaluating efficacy, safety, tolerability, pharmacokinetics and immunogenicity. The trial enrolled 18 patients, began in April 2023 and reached study completion in April 2025. Its focus on MAS-associated HLH positions plonmarlimab within the secondary HLH population where treatment options remain comparatively limited.
