Recent Advances in Drug Development


                                     
                                   
One in eight women is being diagnosed with breast cancer in her lifetime .Chemotherapy, which is one of the most followed therapy for cancer results in destroying the First –line cancer DNA-creating proteins, but BRCA genes have a backup plan that repairs the DNA and is carried out by poly-ADP-ribose polymerases (PARPs).
The new class of breast cancer drug Abemaciclib, which belongs to CDK4/6 inhibitors have shown the most positive effect on metastatic breast cancer, especially in HER2+ breast cancers .This was designed as the breakthrough therapy Abemaciclib and is armed with certain advantages over its rivals. The clinical studies results have put Abemaciclib roughly on par with its competitors in the first-line setting. Side effects that occurred in 20% or more of patients in studies were diarrhoea, nausea and vomiting, leukopenia. Verzenio is another type of medicine which is used to treat a type of breast cancer called HR+/HER2− (hormone receptor positive/human epidermal growth factor receptor 2 negative) and the cancer has spread to other parts of the body .This drug is given in combination with an aromatase inhibitor as initial endocrine-based therapy for the treatment of postmenopausal women or alone in women whose disease has progressed after hormone therapy and prior chemotherapy. Another new class of drug has been developed for the LDL –Cholesterol .The mechanism involves the lowering of cholesterol at higher levels which is proved to be ground breaking. The experiment which is performed with statin cholesterol drug, the new class of drugs is expected to lower cholesterol levels by 75%.The small interfering RNA therapy to lower LDL was given twice a year instead of monthly or weekly like other treatments. They are set to develop new class of agents to lower the LDL levels which will be launched in 2018.

AI applications in Healthcare The field of health AI is far-reaching and covers a large area from wellness to diagnostics to operational technologies.                                                        The fields that are developed are listed accordingly: ·          AI-assisted robotic surgery . In orthopaedic surgery, a form of AI-assisted robotics can analyse data from pre-op medical records to physically guide the surgeon’s instrument in real-time during a procedure. It can also use data from actual surgical experiences to inform new surgical techniques. ·          AI-powered virtual nurse assistants have enormous potential in helping ...

CRISPR - The right technology for the "cure"

Image
CRISPR - Clustered Regulatory Interspaced Short Palindromic Repeats, a family of the DNA sequence in bacteria contains snippets of DNA which are used by the bacterium to detect and destroy the DNA of viruses which is considered as a defense system for the bacteria .This has been used as a effective tool for changing the genes within the organisms. In the treatment of AIDS, DNA of the HIV is inserted into the genome of the host where it can lay dormant for years and its effects can be changed slightly as the virus cannot be made to remain in the inactive state permanently. In the recent days, scientists proved that it is possible to cut the HIV cells out of living cells of patients in a laboratory using CRISPR. Currently, they carried out an experiment in the lab with the rats which had HIV in 99 per cent of their cells. By injecting CRISPR into the rat’s tails, they were able to remove 48 per cent of the virus from the DNA of their body cells. Although the experiments are do...
