Active clinical trials for "Anemia, Hemolytic, Autoimmune"

This is a Phase 2 non-randomized, open-label study to investigate the efficacy, safety and tolerability of RVT-1401 in patients with Warm Autoimmune Hemolytic Anemia.

Primary Objectives: Part A: To evaluate the safety and tolerability of subcutaneous injections of isatuximab in adults with wAIHA Part B: To evaluate the efficacy of the selected dose in adults with wAIHA Secondary Objectives: Part A (Cohorts 2 and 3 only) To evaluate the efficacy of isatuximab in adults with wAIHA To evaluate the durability of response to isatuximab and time to response To evaluate the impact of isatuximab treatment on fatigue Part B To evaluate the safety and tolerability of isatuximab in adults with wAIHA To evaluate the durability of response to isatuximab and time to response To evaluate the impact of isatuximab treatment on fatigue Parts A (all Cohorts) and B To evaluate the effect of isatuximab on markers of hemolysis To characterize the pharmacokinetic profile of isatuximab in adults with wAIHA To evaluate the immunogenicity of isatuximab

This main study objective was to evaluate the safety and tolerability of intravenous (IV) SYNT001 (ALXN1830) in participants with WAIHA.

The investigators have demonstrated that the mean percentage of circulating CD8+ regulatory T (CD8 Tregs) cells is significantly higher in patients with warm hemolytic anemia (wAHAI) in remission than in controls and is correlated to hemoglobin levels. In vitro, low dose of interleukine-2 (IL2) induce the expansion of CD8 Tregs. The objective is to demonstrate that, over a 9 week treatment period; low doses of IL2 can induce the expansion of CD8Tregs in patients with active wAHAI.

Treatment for patients with autoimmune destruction of blood cells is poor. The part of the body that fights infections is called the immune system and white blood cells (WBCs) are part of the immune system. Normally, a person's body creates WBCs to fight infections and eliminates WBCs which have stopped helping the body function. Patients with autoimmune destruction of blood cells have difficulty eliminating old WBCs. The abnormal WBCs build up and can damage other healthy cells, which can lead to anemia, fatigue, jaundice, internal bleeding, infection, and cancer. Few effective medications exist for treatment for patients with autoimmune cytopenias and those commonly used are fraught with side effects. Nevertheless, as scientific understanding of autoimmune diseases has improved, more directed and less toxic therapies are becoming available. A number of groups have been studying the efficacy of a medication called sirolimus in patients with autoimmune diseases. This medicine has been FDA-approved for over 20 years. Sirolimus is a medicine used in children with other diseases. Sirolimus works, in part, by eliminating old and abnormal WBCs. Our group and others have shown that sirolimus is effective in mice with autoimmunity and in children with a rare condition called Autoimmune Lymphoproliferative Syndrome (ALPS). We believe sirolimus will help children with autoimmune cytopenias. We believe it will improve their symptoms and make them less sick. We propose to study sirolimus in children with chronic and/or refractory autoimmune cytopenias.

The conventional treatment in warm-antibody dependent autoimmune haemolytic anaemia (AIHA) is high-dose glucocorticoid, but in more than half of the patients, haemolytic activity will recur after end of treatment or during the gradual reduction in dose of the drug. As a result, many patients will finally be splenectomized or be treated with long-term glucocorticoids or other immunosuppressive drugs as azathioprine or cyclophosphamide. Recent studies have shown however, that some patients will respond to treatment with the chimeric anti-CD 20 antibody Rituximab and is some cases, the response is permanent. In most of the studies, Rituximab has been used in refractory disease or at least as second line treatment. In this study, patients with AIHA are randomized to receive either high-dose prednisolone with gradual reduction in dose over 2-3 months alone or in combination with Rituximab 375 mg/m2 once a week for 4 weeks. The efficacy of Rituximab will be evaluated by a comparison of the patients in the two treatment arms. The primary treatment goal is a reduction in the number of patients who obtain long-term complete or partial remission. The secondary treatment goal is a reduction in patients who will be splenectomised or receive other immunosuppressive drugs. Finally a comparison of side effects of the treatments will take place.

The purpose of this study is to determine whether the combination of low doses of alemtuzumab and rituximab are effective in the treatment of patients with autoimmune cytopenias who has failed on steroids, relapsed after steroids withdrawal or required continuous steroids treatment.

The primary objective of this study is to assess the efficacy of fostamatinib in subjects with warm antibody autoimmune hemolytic anemia (wAIHA).

This was a multi-center, single treatment-group, open-label study to provide sutimlimab to the adult participants with cold agglutinin disease (CAD) who had completed the CARDINAL (NCT number: NCT03347396) or CADENZA (NCT number: NCT03347422) studies and benefitted from sutimlimab treatment in Japan. • Study and treatment duration: the period between the participant's completion of the CARDINAL and CADENZA studies and sutimlimab or other appropriate CAD therapy becoming commercially available to participants in Japan.

Prospective, non-randomized multicenter study on the safety and efficacy of combination therapy with bendamustine and rituximab for chronic cold agglutinin disease.
