Abstract
Recombinant immunotoxins are proteins composed of fragments of monoclonal antibodies fused to truncated protein toxins. No agents of this class are approved yet for medical use, although a related molecule, denileukin diftitox, composed of interleukin-2 fused to truncated diphtheria toxin, is approved for relapsed/refractory cutaneous T-cell lymphoma. Recombinant immunotoxins which have been tested in patients with chemotherapy-pretreated hematologic malignancies include LMB-2 (anti-CD25), BL22 (CAT-3888, anti-CD22) and HA22 (CAT-8015, anti-CD22), each containing an Fv fragment fused to truncated Pseudomonas exotoxin. Major responses were observed with LMB-2 in adult T-cell leukemia, chronic lymphocytic leukemia (CLL), cutaneous T-cell lymphoma, Hodgkins disease, and hairy cell leukemia (HCL). BL22 resulted in a high complete remission rate in patients with HCL, particularly those without excessive tumor burden. HA22, an improved version of BL22 with higher affinity to CD22, is now undergoing phase I testing in HCL, CLL, non-Hodgkins lymphoma, and pediatric acute lymphoblastic leukemia.
Call for Papers in Thematic Issues
"Multidisciplinary Pharmaceutical Drug Design Strategies in the Progress of Drug Discovery"
The process of developing a drug is time- and money-consuming, but also fascinating. The development of numerous computational techniques, synthetic methodologies, formulation-based drug discovery, etc. has improved the drug discovery process. The process of developing new drugs is significantly hampered by drug-poor pharmacodynamics and pharmacokinetic problems. To address these challenges, ...read more
Advances in the Molecular Pathogenesis of Inflammatory Bowel Disease.
This thematic issue will emphasize the recent breakthroughs in the mechanisms of Inflammatory bowel disease (IBD) pathogenesis and devotes some understanding of both Crohn’s and ulcerative colitis. It is expected to include studies about cellular and genetic aspects, which help to precipitate the disease, and the immune system-gut microbiome relations ...read more
Blood-based biomarkers in large-scale screening for neurodegenerative diseases
Disease biomarkers are necessary tools that can be employed in several clinical context of use (COU), ranging from the (early) diagnosis, prognosis, and prediction, to monitoring of disease state and/or drug efficacy. Regarding neurodegenerative diseases, in particular Alzheimer’s disease (AD), a battery of well-validated biomarkers are available, such as cerebrospinal ...read more
Diabetes mellitus: advances in diagnosis and treatment driving by precision medicine
Diabetes mellitus (DM) is a chronic degenerative metabolic disease with ever increasing prevalence worldwide which is now an epidemic disease affecting 500 million people worldwide. Insufficient insulin secretion from pancreatic β cells unable to maintain blood glucose homeostasis is the main feature of this disease. Multifactorial and complex nature of ...read more
