Study Notes
Monoclonal Antibodies: Recent Development in Drug Delivery
- Monoclonal antibodies (mAbs) are manufactured by cloning a unique white blood cell, exhibiting a specific affinity for a particular epitope.
- Therapeutic mAbs are primarily immunoglobulin G (IgG) isotype.
- They target specific antigens and are composed of four polypeptide chains (two similar heavy chains, two similar light chains), with a molecular weight of approximately 150 kD.
- Different types of mAbs exist (e.g., IgA, IgG, IgD, IgM, IgE), with IgG being the most active therapeutically.
- Köhler and Milstein developed the hybridoma technique in 1975 for bulk mAb production.
- Based on their origin, mAbs are classified into four types: murine, chimeric, humanized, and human.
- Over 570 therapeutic mAbs are currently in clinical trials, developed by various pharmaceutical companies.
- Approximately 79 have been approved.
Molecular Mechanisms of mAb Therapy
- mAbs work through various mechanisms, including direct effects on cellular function (e.g., inhibiting signaling pathways or inducing apoptosis).
- Targeting immune effector processes is crucial for tumor targeting.
- MAbs can also be used to deliver payloads (e.g., cytotoxic drugs/radioisotopes).
Advantages and Disadvantages of mAbs
- Advantages include higher efficacy, safety, lower toxicity, fewer side effects, and increased patient survival compared to other treatments.
- High specificity makes mAbs good for highly targeted therapies (and reduces harm to healthy cells).
- Limitations include high production costs.
- Limited tissue penetration and decreased immune system interactions.
Formulation Challenges of mAbs
- Protein structural changes are a risk during various treatment stages.
- mAbs can be damaged by various factors like high temperatures, pH changes, and exposure to stress.
- These can lead to instability concerns, reducing yield and possibly interfering with their efficacy.
Novel Drug Delivery Systems for mAbs
- Nanoparticles, hydrogels, and microspheres are utilized to enhance mAb delivery.
- These approaches aim to improve pharmacokinetics, reduce toxicity, ensure sustained release, and enhance target selectivity.
- PLGA conjugated NPs, used in clinical trials, are aimed at active targeting of tumor cells and are more efficient than free drug.
Future Trends in mAbs
- Continued development of antibody therapy and the creation of more effective and safe mAbs for various diseases are expected.
- The focus areas include engineering human/humanized mAbs to enhance therapeutic potential.
- Development of more effective mAbs, based on the understanding of disease mechanisms, using advanced technologies (like genetically engineered mice, phage display, single B cell approaches).
