Journal: Sutimlimab in Cold Agglutinin Disease. (Pubmed Central) - Apr 23, 2021 P3 In patients with cold agglutinin disease who received sutimlimab, selective upstream inhibition of activity in the classic complement pathway rapidly halted hemolysis, increased hemoglobin levels, and reduced fatigue. (Funded by Sanofi; CARDINAL ClinicalTrials.gov number, NCT03347396.).

P3 Of the 79 antibodies in late-stage studies, 40 were undergoing evaluation as treatments for cancer, and potentially 9 of these (belantamab mafodotin, oportuzumab monatox, margetuximab, dostarlimab, spartalizumab, 131I-omburtamab, loncastuximab tesirine, balstilimab, and zalifrelimab) may enter regulatory review in late 2019 or in 2020. Overall, the biopharmaceutical industry's clinical pipeline of antibody therapeutics is robust, and should provide a continuous supply of innovative products for patients in the future.

Review, Journal: New Insights in Autoimmune Hemolytic Anemia: From Pathogenesis to Therapy Stage 1. (Pubmed Central) - Dec 3, 2020 Several new drugs are under development including B-cell directed therapies (ibrutinib, venetoclax, parsaclisib) and inhibitors of complement (sutimlimab, pegcetacoplan), spleen tyrosine kinases (fostamatinib), or neonatal Fc receptor. Here, a comprehensive review of the main clinical characteristics, diagnosis, and pathogenic mechanisms of AIHA are provided, along with classic and new therapeutic approaches.

[VIRTUAL] Long-Term Safety and Efficacy of Sutimlimab in Patients with Chronic Immune Thrombocytopenia (Channel 17 (Virtual Meeting)) - Nov 5, 2020 - Abstract #ASH2020ASH_1567; This is continued clinical evidence that the complement pathway plays a role in thrombocytopenia in a subset of patients with ITP. These sustained responses suggest ≥1 additional pathophysiologic explanation for the clinical heterogeneity of ITP and provide a strong platform for continued evaluation of CP inhibition in ITP treatment.

Inhibition of Complement C1s with Sutimlimab in Patients with Cold Agglutinin Disease (CAD): Results from the Phase 3 Cardinal Study (Hall D, Level 2 (Orange County Convention Center)) - Nov 21, 2019 - Abstract #ASH2019ASH_6614; P3 Conclusions The Phase 3 Cardinal study shows that sutimlimab, a first-in-class selective inhibitor of the CP, has a rapid and sustained treatment effect in CAD by preventing hemolysis, significantly increasing Hb, and improving QOL (FACIT-F) . These results demonstrate that targeting the CP represents a novel, effective therapeutic approach for the management of CAD and indicate that sutimlimab has the potential to change treatment practices for patients with this condition.

Predictors of Response to Erythropoietin in Autoimmune Hemolytic Anemia (Hall B, Level 2 (Orange County Convention Center)) - Nov 7, 2019 - Abstract #ASH2019ASH_5223; Predictors of response were severe anemia and low levels of endogenous EPO, as well as, shorter disease duration and a lower burden of previous treatments . These data suggest an early use of EPO in this setting in order to overcome inadequate bone marrow compensatory ability.

Preclinical, Journal: C1s Inhibition by BIVV009 (Sutimlimab) Prevents Complement-Enhanced Activation of Autoimmune Human B Cells In Vitro. (Pubmed Central) - Oct 27, 2019 Strikingly, CP antagonism suppressed human Ig-induced activation of B cells derived from patients with rheumatoid arthritis. These results suggest that clinical use of CP inhibitors in autoimmune patients may not only block complement-mediated tissue damage, but may also prevent the long-term activation of autoimmune B cells and the production of autoantibodies that contribute to the underlying pathologic condition of these diseases.

Review, Journal: Novel insights into the treatment of complement-mediated hemolytic anemias. (Pubmed Central) - Sep 17, 2019 Upstream complement modulation is currently being investigated and appears to be a highly promising therapy, and two such agents have entered phase II and III trials. Of these, the anti-C1s monoclonal antibody sutimlimab has shown favorable activity in CAD, while the anti-C3 cyclic peptide pegcetacoplan appears to be promising in PNH as well as CAD, and may also have a therapeutic potential in wAIHA.

Journal: Current and emerging treatment options for autoimmune hemolytic anemia. (Pubmed Central) - May 22, 2019 The latter may give hints for targeted therapies (either B or T cell directed) and for new immunomodulatory drugs. Future studies on the genomic landscape in AIHA will further help in designing the best choice, sequence and/or combination of targeted therapies.

Journal: Novel Approaches to Block Complement. (Pubmed Central) - Apr 24, 2019 Moreover, modified apheresis techniques for preferential removal of macromolecules, including C1q, may allow for efficient complement depletion, in addition to antibody removal. The availability of effective strategies to interfere with the CP, as well as innovative approaches targeting other pathways, some of them already being tested in clinical trials, will help us figure out how complement contributes to acute and chronic graft injury, and hopefully provide us with new ways to more efficiently counteract rejection.

Clinical, Journal: How I manage patients with cold agglutinin disease. (Pubmed Central) - Mar 29, 2019 Second-line options are rituximab-fludarabine in fit patients or, although less strongly documented, a bortezomib-based regimen. Therapies targeting the classical complement pathway are promising, and the complement C1s inhibitor, BIVV009, has shown favourable results in preliminary studies.
