Monoclonal antibody therapy

History
Four major antibody types that have been developed are
Murine
Initial therapeutic antibodies were murine
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
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
Alzheimer's disease
Alzheimer's disease (AD) is a multi-faceted, age-dependent, progressive neurodegenerative disorder, and is a major cause of dementia.
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.
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
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
Antibody-directed enzyme prodrug therapy
Antibody-drug conjugates
Immunoliposome therapy
Immunoliposomes are antibody-conjugated
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
