Treatment of Septic Shock

[0205]JR is a 72-year-old white male with a history of non-Hodgkin's lymphoma having past therapy with various cytotoxic drugs, corticosteroids, as well as Rituxan®, and presenting with stable lymphoma and a past history of several infections that required prolonged antibiotic therapy. He is admitted to the emergency department after being evaluated by his general practitioner with high temperature (40.7° C.), chills, dyspnea, palpitations, agitation, some confusion, and cool extremities. Examination reveals tachycardia (>90 / min), hypotension (95 / 60 mm Hg), especially upon standing, and a reduced urine output (800 mL / d), and signs of pneumonia. Tests show a low oxygen tension and acidosis, a blood count not detecting infection, but instead neurtopenia (3,500 WBC / mL, with 10% bands), platelets of 48,000, Hg of 6 g / dL, chest x-ray reveals a generalized pneumonia, blood tests indicate reduced renal function, with abnormal serum creatinine (3 mg / dL) and BUN leve...

Therapy of Systemic Lupus Erythematosus (SLE)

[0206]S.R. is a 32-year-old African-American female diagnosed 5 years earlier with SLE, when she presented with a globerulonephritis (WHO grade 3), serositis, polyarthritis, and a vasculitic rash. She had prior therapy with corticosteroids (range of 15-60 mg per day) and hyrdoxychloroquine (200 mg / day), and at a later time also azathioprine (100 mg / day) and a course of cyclophosphamide) because of persistent disease. Over the years, she experienced flares of her SLE, presenting with polyarthritis, lethargy, skin rash, and serositis. She now presents with persistently active disease and unresponsive to conventional therapies, but is maintained on 40 mg prednisone daily. She is given humanized anti-CD22 monoclonal antibody, epratuzumab, at 400 mg i.v. over 1 hr, repeated once in each of the following two weeks. Four weeks after the third infusion, her circulating B-lymphocytes are reduced by 40% from baseline prior to therapy, but her Hg le...

Therapy of Non-Hodgkin's Lymphoma (NHL)

[0207]SL is a 66-year-old white male with a history of diffuse large-cell NHL that has relapsed after therapy with CHOP and rituximab, and is now presenting with fever, lung and mediastinal infiltrates, enlarged cervical and axillary lymph nodes, and evidence of bone marrow involvement based on aspiration and cytology. He receives 6 weekly infusions of two humanized antibodies, one against TNF-α and the other against MIF, each given on the same day sequentially, over a 3-4-hr infusion for each, at a dose of each of 450 mg. Twenty-four hours after the last infusion, his examination indicates that he has no major toxicities to the therapy, and some palpable softening of his cervical and axillary lymph nodes. At the next follow-up examination in 8 weeks, almost all of his cervical and about half of these axillary nodes have disappeared, and his chest x-ray and CT scan show evidence of about a 60% shrinkage of his pulmonary and mediastinal infiltra...

Abstract

Methods and compositions for immunotherapy of inflammatory and immune-dysregulatory diseases, using multispecific antagonists that target at least two different markers are disclosed. The different targets include (i) proinflammatory effectors of the innate immune system, (ii) coagulation factors, and (iii) targets specifically associated with an inflammatory or immune-dysregulatory disorder, with a pathologic angiogenesis or cancer, or with an infectious disease, wherein the targets included in group (iii) are neither a proinflammatory effector of the immune system nor a coagulation factor. When the multispecific antagonist reacts specifically with a target associated with an inflammatory or immune-dysregulatory disorder, with a pathologic angiogenesis or cancer, or with an infectious disease, it also binds specifically with at least one proinflammatory effector of the immune system or at least one coagulation factor. Thus, the multispecific antagonist contains at least one binding specificity related to the diseased cell or condition being treated and at least one specificity to a component of the immune system, such as a receptor or antigen of B cells, T cells, neutrophils, monocytes and macrophages, and dendritic cells, a modulator of coagulation, or a proinflammatory cytokine. The multispecific antagonists are used in the treatment of various diseases that are generated or exacerbated by, or otherwise involve, proinflammatory effectors of the innate immune system or coagulation factors. Such diseases more particularly include acute and chronic inflammatory disorders, autoimmune diseases, giant cell arteritis, septicemia and septic shock, coagulopathies (including diffuse intravascular coagulation), neuropathies, graft versus host disease, infectious diseases, acute respiratory distress syndrome, granulomatous diseases, transplant rejection, asthma, cachexia, myocardial ischemia, and atherosclerosis. Other diseases also responsive to these therapies include cancers and conditions with pathological angiogenesis.

Description

[0001]This application is a divisional of U.S. Ser. No. 11 / 296,432, filed on Dec. 8, 2005, □ which claims the benefit of U.S. Provisional Application No. 60 / 634,076, filed on Dec. 8, 2004.BACKGROUND OF THE INVENTION[0002]A. Field of the Invention[0003]The invention relates generally to methods and compositions for immunotherapy of inflammatory and immune-dysregulatory diseases, using multispecific antagonists that target at least two different markers. The markers are antigens and / or receptors on lymphocytes, macrophages, monocytes, or dendritic cells (DCs). The invention particularly relates to methods and compositions for modulating receptors on immune-targeting and immune-processing cells using specific antibodies and antibody heteroconjugates to bind to the cells and their receptors, to effect a treatment of various diseases that are generated or exacerbated by, or otherwise involve, these cells and their receptors. Such diseases more particularly include acute and chronic infla...
