1st FDA approved mAbMuromonab
Production process usually starts with generation of mAb-producing cells (i.e. hybridomas) by fusing myeloma cells with desired antibody-producing splenocytes (e.g. B cells), typically sourced from animals, usually mice.Monoclonal antibodies (mAb)
Used to prevent, treat, cure, diagnose, or mitigate human diseases caused by genetic disorders. Medical intervention is based on the modification of the genetic material of the living cells.Human Gene Therapy
the branch of medicine concerned with the uses, effects, and modes of action of drugs.Pharmacology
2 major branches of Pharmacology1 Pharmacokinetics 2 Pharmacodynamics
refers to the absorption, distribution, metabolism, and excretion of drugs.Pharmacokinetics
which physiological effects of drugs, including drug mechanism of action.Pharmacodynamics
LADME ProcessInput 1 Liberation 2 Absorption 3 Distribution Output 4 Metabolism 5 Excretion
1 The release of drug from its dosage form 2 The movement of drug from the site of administration to the blood circulation1 Liberation 2 Absorption
1 The chemical conversion or transformation of drugs into compounds which are easier to eliminate 2 The elimination of unchanged drug or metabolite from the body via renal, biliary, or pulmonary processes 3 The action of the body to the drug administered1 Metabolism 2 Excretion 3 Response
The LADMERT system is key to the following tasks:1 Development of new active compounds, analogs, or derivatives; 2 Development of dosage forms with desired release characteristics; 3 Determination of pharmacokinetic parameters and pharmacokinetic drug product profiles; 4 Determination and evaluation of bioavailability; 5 Selection of the most appropriate route of administration; 6 Determination of effective dose sizes; and 7 Adjustment of dosage regimen to achieve a desired therapeutic concentration of drug in the body based on physiologic (e.g., body weight, age, sex) and pathologic (e.g., renal, hepatic, or heart failure; obesity; malnutrition) factors.
involves the study of the adverse effects of chemical substances on living organisms and the practice of diagnosing and treating exposures to toxins and toxicants. As part of the IND application, FDA requires an integrated summary of toxicological effects of the drug in animals and in vitro.Toxicology
