Immunotherapy one sole aim is to build the immune system to fight cancer

Immunotherapy is an important part of treatment to fight some types of cancer by boosting the patient’s immune system. This therapy can be used in different ways, including stimulating the body’s immune system to attack cancer cells and providing components of the immune system (man-made immune system proteins called antibodies).

After a long time, researchers found that the immune system could affect certain cancers. In the late 1800s, William Coley first recognized that in cancer patients, getting an infection after surgery. He began treatment of cancer patients with certain kinds of bacteria (Coley toxin).

The main types of immunotherapy used in the treatment of cancer include monoclonal antibodies, cancer vaccine and non-specific immunotherapy. Monoclonal antibodies boost the immune system and can be designed to attack a very specific protein that helps in the growth of cancer cell. These antibodies stop cancer cells from growing by binding to those proteins. Due to this reason, these types of treatment are also called targeted therapy. Advance forms of monoclonal antibodies are less likely to cause an immune reaction. 

Vaccines are now often given along with adjuvants that help boost the immune response.  Researchers are still studying to find the best way to give vaccines for better response when used alone. 

Non-specific immune therapies do not target specific part of cancer cells. Cytokines are those chemicals which are made by some immune system cells. They are controlling the growth and activity of other immune system cells. Interleukins (group of cytokines) helps in growth of immune system cells. Interleukin-2 (man-made version) is approved to treat metastatic cancer and kidney cancer. Some other drugs in non-specific way that are not naturally found in the body, but boost the immune system are known as immune modulating drugs.

Pharmacovigilance act as monitor of drug safety.

Pharmcovigilance is the pharmacological science and activities relating to the assessment, understanding, detection and prevention of adverse effects or any other drug related problem. Pharmacovigilance has a major role to improve public health and safety in relation to drugs and to contribute in the assessment of benefits, effectiveness and risk of drugs, encouraging their safe, rational and more effective use. It is also to promote education and clinical trials. Its effective communication to health professionals and the public. Before a drug launch into the market to reach the public on time and cost-efficient manner, it passes through all phases of clinical trials and the goal of company.

Basic needs of pharmacovigilance relating to tests on animals are insufficient to predict human safety due to this reason limited number of patient are selected in clinical trials for limited duration of time. By the time of licensing exposure of less than 5000 human subjects to a drug allows only the common adverse drug event to be estimated. Information about serious adverse reactions is any untoward medical occurrence that any dose results in significant disability and death, chromic toxicity, use in special groups such as children and pregnant woman. Main steps under pharmacovigilance, includes identifying information about risk associated with drugs, preventing harm to patients and post marketing surveillance. An adverse drug reaction is a response to a medicine which is noxious and unintended, and which occurs at normal dose.

In National Pharmacovigilance program (NPP), the nationwide clinical trials programmed, sponsored and coordinated by the country’s central drug regulatory agency (Central Drug Standard Control Organization to establish and manage a data base of adverse drug reaction for making informed regulatory decisions regarding marketing authorization of drugs in India for ensuring safety of drugs). Functions of NPP is to monitor the adverse drug reactions of medicines, maintain contacts with international regulatory bodies working in pharmacovigilance and exchange information on drug safety, assess the regulatory information about drug safety, and provide information to end-users through adverse drug reaction news bulletins and seminars.

Clinical Research: One sole aim! Deliver a better and quality healthcare

Clinical Research is a process to make advancement of medical knowledge and improve patient care. A systematic investigation in human subjects for evaluating the safety and efficacy of any new drug.

Clinical research is the scientific term to examine the safety and efficacy of a new medication intended for human healthy living. It is done before to the launch of the drug into the market. The main purpose of clinical trials is research, so the studies follow strict protocols. These protocols protect patients and provide reliable trial results to improved health care.

Clinical trials can only start after pre-clinical studies, including laboratory studies like in vitro and in-vivo tests on animals, which have shown that the experimental drug is considered safe and effective. Preclinical provide a general pharmacokinetic, pharmacological and toxicological profile of the new drug obtained from animal’s studies. However, no animal is sufficiently similar to human’s pharmacokinetics and Pharmacodynamics. Due to this reason, the experimental drug must also be tested on humans.

Clinical trial is conducted in four phases, which are mentioned below:

Phase I: To determine safety and identify adverse event and side effects. Researchers test an experimental drug or treatment on a small group of healthy human volunteer (20–80) for several months. If the drug is successfully passes through this phase 1, then move to the next level of testing called phase II.

Phase II: To determine whether the drug does for what it is made for and to further determine safety and identify side effects and to identify the common risks of the drug. The other important factors that are also considered in this phase are pharmacokinetics, pharmacodynamics, efficacy at different doses, drug disease interaction, drug- drug interaction, bioavailability of the drug and finally the patient's safety. The experimental drug or treatment is given to a larger group of unhealthy human volunteer (100–300) for several months to several years. When the drug successfully passes through this phase, then move to the next level of testing called phase III.

Phase III: To determine and to confirm its safety and effectiveness, drug disease interactions, drug-drug interactions, dosage intervals and finally risk/ benefit of the drug and collect information to compare the data from standard or equivalent effective drugs. The experimental drug or treatment is given to larger group of unhealthy human volunteers (1,000–3,000) for several months to several years. This phase is the last stage before the drug is clinically approved by FDA as this phase provides enough information about the experimental drug, if it is safe or not and if it is safe to be launched in the market.

Phase IV: The long-term effects of drugs or treatment are studied after the drug is permitted to be sold in the market. This phase is also known as Post-marketing surveillance studies for toxicity. This phase may be undertaken by regulatory authorities.

The Food and Drug Administration is responsible for protecting the public health by assuring the safety, efficacy and quality of new drugs developed. The FDA approves the drug that passes all the phases of clinical trial and after that it is made available to the general public. Schedule “Y” is providing requirements and guidelines for permission to import and /or manufacture of new drugs to undertake clinical trials or for sale.

Clinical trials are designed to suite you’re scientific, as well as regulatory requirements with the known SOPs, ICH, and CFR at Global Allied Pharmaceuticals (GAP). GAP is committed to providing reliable information and protecting the volunteers of clinical trials. Unreasonable risk is not to be tolerated in protecting the safety of the volunteers.

Health care Industries Is Advancing: Immunotherapy Is the Example

Immunotherapy is a scientific term defined as the treatment of disease by including, activation, or suppressing an immune response. Immunotherapy is also sometimes called biological therapy. It is treatment that uses certain parts of the immune system to fight diseases such as cancer. Cell based immunotherapy’s are proven to be more effective for some cancers. Immune effectors cells such as lymphocytes, macrophages, dentritic cells, natural killer cells, cytotoxic T lymphocytes, etc., work together to defend the body against cancer by targeting abnormal antigens expressed on the surface of the tumor due to mutation.

Passive immunity is the transfer of active humoral immunity from one individual to another. This immunity can occur naturally through placenta, when maternal antibodies are transferred to the fetus, and can also be induced artificial, when high levels of human antibodies specific for a pathogen or toxin are transferred to non-immune individuals and used when there is a high risk of infection and insufficient time for the body to develop its own immune response.

Immunostimulants are substances like drugs and nutrients that stimulate the immune system by including activation or increasing activity of any of its components. There are two main categories of immunostimulants are specific and non-specific. Specific immune- Oncology provide antigen specificity in immune response, such as vaccines or antigens. Non-specific immunostimulants act as irrespective of antigenic specificity to augment immune response of other antigen or stimulate components of the immune system without antigenic specificity, such as adjuvant. Many endogenous substances are non-specific immunostimulants like female sex hormones are known to stimulate both adaptive and innate immune responses. Other hormones appear to regulate the immune system as well, most notably vitamin D, prolactin and growth hormone.

Cancer immunotherapy is the use of the immune system to reject cancer. The main assumption is stimulating the patient’s immune system to attack the malignant tumor cells that are responsible for the disease. In late 1800s Dr William Coley first noted that getting an infection after surgery seemed to help some cancer patients. He starts treating cancer patients by infecting them with certain kinds of bacteria, which came to be called as Coley toxins.
