Antibody structure and function

Fc (fragment crystallizable region) part of the molecule. The Fab fragments contain the variable domains, which consist of three antibody hypervariable amino acid domains responsible for the antibody specificity embedded into constant regions. The four known IgG subclasses are involved in antibody-dependent cellular cytotoxicity.[2]
active immunity. The advantage of active monoclonal antibody therapy is the fact that the immune system will produce antibodies long-term, with only a short-term drug administration to induce this response. However, the immune response to certain antigens may be inadequate, especially in the elderly. Additionally, adverse reactions from these antibodies may occur because of long-lasting response to antigens.[4] Passive monoclonal antibody therapy can ensure consistent antibody concentration, and can control for adverse reactions by stopping administration. However, the repeated administration and consequent higher cost for this therapy are major disadvantages.[4]

Monoclonal antibody therapy may prove to be beneficial for

autoimmune diseases, and neurological disorders that result in the degeneration of body cells, such as Alzheimer's disease. Monoclonal antibody therapy can aid the immune system because the innate immune system responds to the environmental factors it encounters by discriminating against foreign cells from cells of the body. Therefore, tumor cells that are proliferating at high rates, or body cells that are dying which subsequently cause physiological problems are generally not specifically targeted by the immune system, since tumor cells are the patient's own cells. Tumor cells, however are highly abnormal, and many display unusual antigens. Some such tumor antigens are inappropriate for the cell type or its environment. Monoclonal antibodies can target tumor cells or abnormal cells in the body that are recognized as body cells, but are debilitating to one's health.[citation needed

History

scFv, single-chain Fv fragment.[5]

malignant neoplasms found mAb therapy of limited and generally short-lived success with blood malignancies.[8][9] Treatment also had to be tailored to each individual patient, which was impracticable in routine clinical settings.[citation needed
]

Four major antibody types that have been developed are

murine, chimeric, humanised and human. Antibodies of each type are distinguished by suffixes on their name.[citation needed
]

Murine

Initial therapeutic antibodies were murine

analogues (suffix -omab). These antibodies have: a short half-life in vivo (due to immune complex formation), limited penetration into tumour sites and inadequately recruit host effector functions.[10] Chimeric and humanized antibodies have generally replaced them in therapeutic antibody applications.[11] Understanding of proteomics has proven essential in identifying novel tumour targets.[citation needed
]

Initially, murine antibodies were obtained by hybridoma technology, for which Jerne, Köhler and Milstein received a Nobel prize. However the dissimilarity between murine and human immune systems led to the clinical failure of these antibodies, except in some specific circumstances. Major problems associated with murine antibodies included reduced stimulation of

Chimeric and humanized

To reduce murine antibody

]

Humanised antibodies are produced by grafting murine hypervariable regions on amino acid domains into human antibodies. This results in a molecule of approximately 95% human origin. Humanised antibodies bind antigen much more weakly than the parent murine monoclonal antibody, with reported decreases in affinity of up to several hundredfold.

Human monoclonal antibodies

Human monoclonal antibodies (suffix -umab) are produced using

immunoglobulin genes into the murine genome and vaccinating the transgenic mouse against the desired antigen, leading to the production of appropriate monoclonal antibodies.[11] Murine antibodies in vitro are thereby transformed into fully human antibodies.[3]

The heavy and light chains of human IgG proteins are expressed in structural polymorphic (allotypic) forms. Human IgG allotype is one of the many factors that can contribute to immunogenicity.[16][17]

Targeted conditions

Cancer

Anti-cancer monoclonal antibodies can be targeted against malignant cells by several mechanisms. Ramucirumab is a recombinant human monoclonal antibody and is used in the treatment of advanced malignancies.[18] In childhood lymphoma, phase I and II studies have found a positive effect of using antibody therapy.[19]

Monoclonal antibodies used to boost an anticancer immune response is another strategy to fight cancer where cancer cells are not targeted directly. Strategies include antibodies engineered to block mechanisms which downregulate anticancer immune responses, checkpoints such as PD-1 and CTLA-4 (checkpoint therapy),[20] and antibodies modified to stimulate activation of immune cells.[21]

Autoimmune diseases

Monoclonal antibodies used for

rejection of kidney transplants.[22] Omalizumab inhibits human immunoglobulin E (IgE) and is useful in moderate-to-severe allergic asthma.[citation needed
]

Alzheimer's disease

Alzheimer's disease (AD) is a multi-faceted, age-dependent, progressive neurodegenerative disorder, and is a major cause of dementia.

Amyloid hypothesis, the accumulation of extracellular amyloid beta peptides (Aβ) into plaques via oligomerization leads to hallmark symptomatic conditions of AD through synaptic dysfunction and neurodegeneration.[24] Immunotherapy via exogenous monoclonal antibody (mAb) administration has been known to treat various central nervous disorders. In the case of AD, immunotherapy is believed to inhibit Aβ-oligomerization or clearing of Aβ from the brain and thereby prevent neurotoxicity.[25]

However, mAbs are large molecules and due to the blood–brain barrier, uptake of mAb into the brain is extremely limited, only approximately 1 of 1000 mAb molecules is estimated to pass.[25] However, the Peripheral Sink hypothesis proposes a mechanism where mAbs may not need to cross the blood–brain barrier.[26] Therefore, many research studies are being conducted from failed attempts to treat AD in the past.[24]

However, anti-Aβ vaccines can promote antibody-mediated clearance of Aβ plaques in transgenic mice models with amyloid precursor proteins (APP), and can reduce cognitive impairments.

passive immunotherapy. In this case the antibodies is produced externally in cultured cells and are delivered to the patient in the form of a drug. In mice expressing APP, both active and passive immunization of anti-Aβ antibodies has been shown to be effective in clearing plaques, and can improve cognitive function.[24]

Currently, there are two FDA approved antibody therapies for Alzheimer's disease, Aducanemab and Lecanemab. Aducanemab has received accelerated approval while Lecanemab has received full approval.[25] Several clinical trials using passive and active immunization have been performed and some are on the way with expected results in a couple of years.[24][25] The implementation of these drugs is often during the early onset of AD. Other research and drug development for early intervention and AD prevention is ongoing. Examples of important mAb drugs that have been or are under evaluation for treatment of AD include Bapineuzumab, Solanezumab, Gautenerumab, Crenezumab, Aducanemab, Lecanemab and Donanemab.[25]

Bapineuzumab

vasogenic edema,[28] a cytotoxic condition where the blood brain barrier has been disrupted thereby affecting white matter from excess accumulation of fluid from capillaries in intracellular and extracellular spaces of the brain.[29]

In Phase III clinical trials, Bapineuzumab showed promising positive effect on biomarkers of AD but failed to show effect on cognitive decline. Therefore, Bapineuzumab was discontinued after failing in the Phase III clinical trial.[29]

Solanezumab

Solanezumab, an anti-Aβ mAb, targets the N-terminus of Aβ. In Phase I and Phase II of clinical trials, Solanezumab treatment resulted in cerebrospinal fluid elevation of Aβ, thereby showing a reduced concentration of Aβ plaques. Additionally, there are no associated adverse side effects. Phase III clinical trials of Solanezumab brought about significant reduction in cognitive impairment in patients with mild AD, but not in patients with severe AD. However, Aβ concentration did not significantly change, along with other AD biomarkers, including phospho-tau expression, and hippocampal volume. Phase III clinical trials of Solanezumab failed as it did not show effect on cognitive decline in comparison to placebo. [30]

Lecanemab

Lecanemab (BAN2401), is a humanized mAb that selectively targets toxic soluble Aβ protofibrils,[31] In phase 3 clinical trials,[32] Lecanemab showed a 27% slower cognitive decline after 18 months of treatment in comparison to placebo.[33][34] The phase 3 clinical trials also reported infusion related reactions, amyloid-related imaging abnormalities and headaches as the most common side effects of Lecanemab. In July 2023 the FDA gave Lecanemab full approval for the treatment of Alzheimer's Disease [35] and it was given the commercial name Leqembi.

Preventive trials

Failure of several drugs in Phase III clinical trials has led to AD prevention and early intervention for onset AD treatment endeavours. Passive anti-Aβ mAb treatment can be used for preventive attempts to modify AD progression before it causes extensive brain damage and symptoms. Trials using mAb treatment for patients positive for genetic risk factors, and elderly patients positive for indicators of AD are underway. This includes anti-AB treatment in Asymptomatic Alzheimer's Disease (A4), the Alzheimer's Prevention Initiative (API), and DIAN-TU.[26] The A4 study on older individuals who are positive for indicators of AD but are negative for genetic risk factors will test Solanezumab in Phase III Clinical Trials, as a follow-up of previous Solanezumab studies.[26] DIAN-TU, launched in December 2012, focuses on young patients positive for genetic mutations that are risks for AD. This study uses Solanezumab and Gautenerumab. Gautenerumab, the first fully human MAB that preferentially interacts with oligomerized Aβ plaques in the brain, caused significant reduction in Aβ concentration in Phase I clinical trials, preventing plaque formation and concentration without altering plasma concentration of the brain. Phase II and III clinical trials are currently being conducted.[26]

Therapy types

Radioimmunotherapy

lymphomas, as these are highly radio-sensitive malignancies. To limit radiation exposure, murine antibodies were chosen, as their high immunogenicity promotes rapid tumor clearance. Tositumomab is an example used for non-Hodgkin's lymphoma.[citation needed
]

Antibody-directed enzyme prodrug therapy

Antibody-directed enzyme prodrug therapy (ADEPT) involves the application of cancer-associated monoclonal antibodies that are linked to a drug-activating enzyme. Systemic administration of a non-toxic agent results in the antibody's conversion to a toxic drug, resulting in a cytotoxic effect that can be targeted at malignant cells. The clinical success of ADEPT treatments is limited.[36]

Antibody-drug conjugates

Antibody-drug conjugates (ADCs) are antibodies linked to one or more drug molecules. Typically when the ADC meets the target cell (e.g. a cancerous cell) the drug is released to kill it. Many ADCs are in clinical development. As of 2016 a few have been approved.[citation needed
]

Immunoliposome therapy

Immunoliposomes are antibody-conjugated

liposomes. Liposomes can carry drugs or therapeutic nucleotides and when conjugated with monoclonal antibodies, may be directed against malignant cells. Immunoliposomes have been successfully used in vivo to convey tumour-suppressing genes into tumours, using an antibody fragment against the human transferrin receptor. Tissue-specific gene delivery using immunoliposomes has been achieved in brain and breast cancer tissue.[37]

Checkpoint therapy

Checkpoint therapy uses antibodies and other techniques to circumvent the defenses that tumors use to suppress the immune system. Each defense is known as a checkpoint. Compound therapies combine antibodies to suppress multiple defensive layers. Known checkpoints include

PD-1 targeted by nivolumab and pembrolizumab and the tumor microenvironment.[20]

The

CXCL12-regulated T cell exclusion.[38]

Economics

Since 2000, the therapeutic market for monoclonal antibodies has grown exponentially. In 2006, the "big 5" therapeutic antibodies on the market were

autoimmune and inflammatory disorders, 'AIID') and rituximab (oncology and AIID) accounted for 80% of revenues in 2006. In 2007, eight of the 20 best-selling biotechnology drugs in the U.S. are therapeutic monoclonal antibodies.[42] This rapid growth in demand for monoclonal antibody production has been well accommodated by the industrialization of mAb manufacturing.[43]
