CAR-T Cell Therapy

Leukemia is a cancer of blood cells, specifically white blood cells that are responsible for fighting infection. However, the abnormal cells in leukemia do not function in the same way as normal white blood cells. Leukemia cells continue to grow and divide, eventually crowding out normal blood cells. The end result is that it becomes difficult for the body to fight infections, control bleeding and transport oxygen (Medicine Net, 2015). It is estimated that each year, approximately 30,800 individuals will be diagnosed with leukemia in the United

It will consist of 10 arms or sub-studies. The study requires the participants to be at least 18 years or older to enroll. The participants must have advance solid tumors and lymphomas that are no longer responding to standard therapy and have begun to grow. The participants will undergo DNA sequencing to identify genetic abnormalities that may respond to the targeted drugs selected for the trail. These drugs that will be given to the participants will have either been approved by the U.S. Food and Drug Administration or are still being tested in other clinical trials but have shown effectiveness against tumors with genetic alterations. 20 to 25 drugs will be tested in different arms of the

Transition: Now that I have talked about the basics regarding Acute Lymphoblastic Leukemia, let’s talk about the new approaches we are taking to combat this disease.

Leukemia broadly describes conditions that affect erythropoiesis in the bone marrow, lymphatic system, and spleen. As with all other cancers, leukemia begins from the mutation of DNA in certain cells. Classifications of leukemias are based on the age of onset and the leukocyte involved (Lewis et al. 2014, 665). The most common leukemia is chronic lymphocytic leukemia (CLL), accounting for approximately 30% of cases in the United States (Copstead and Banasik 2013, 222). The normal function of the bone marrow, spleen, and liver becomes interrupted by the invasion of malignant lymphocytes (B cells); since the B cells are functionally inactive, a patient becomes more susceptible to infections. The sluggish progression of CLL unfortunately leads to late diagnoses and poor prognosis (Lewis et al. 2014, 665). Patients that become symptomatic in later stages will experience fatigue, weight loss, anorexia, and an increased susceptibility to infection, due to abnormal antibody production. Patient specific factors such as age, disease progression, and medication side effects will determine the course of treatment (Copstead and Banasik 2013, 223). The fragile state of patients with CLL requires continuous examination of drug therapy and interventions to prevent further complications.

Throughout the years, a diagnosis of cancer has been an uphill battle for both patients and doctors alike. An individual faces an incurable disease that is notorious for taking away lives by the numbers. Victims of the pathogen are at risk of it spreading to other parts of the body, facing an excruciating amount of pain and eventual death. If caught in an early stage the carcinogen can be removed through various treatments. However, throughout the years treatments have been limited to patients which can cause physical, and financial hardships. It is not until the age of biotechnology and more scientific research occurred that immunotherapy became a possible treatment for those in need. Immunology has been in the scientific world since the

Finding a panacea for cancer will be an arduous task with a very lengthy and discouraging trial and error period. Inevitably there will be some trying hurdles to get past in search of this cancer panacea, but, one that seems to be the most difficult to get passed is the severity and variety of the case presented. Doctors see this as overwhelming and very daunting since they do not want to get a patient’s hopes up if the medicine turns out not to work, or cause things to get worse. If doctors believe they have found this new and astonishing drug that cures all cancer at all stages and they prescribe it but turns out to only make the cancer worse, they will have to live knowing that they hurt all of these people and their families forever. In

Wolchok does not name specific instruments used for measurements, discuss reliability in terms of type and size of reliability coefficients, or name specific control procedures. The success rates of the different types of treatments are determined by visible tumor growth difference after treatment is administered as well as overall survival. Wolchok also notes that measuring success among immunotherapy treatments can be difficult and take nearly double the time to see results than other treatment methods. Even in patients whose brain scans show tumor growth 12 weeks after the treatment has begun, the growth may be indicative of T cells and other immune cells flooding the tumor. Henceforth, the difficulty of determining success among patients being treated with immunotherapies is far more perplexing than patients who have undergone chemotherapy or

For many types of cancers, we have been using the same base drug (first line treatment) for ten years or even longer. As companies find new drugs to fight the cancers, they hope that it will be the miracle drug that will eradicate the cancer, but it usually isn’t. When they reach this conclusion, instead of returning to the chalkboard and continuing to work to improve the drug, they put the drug on the market as is, and hope it will achieve something. Not only are they putting these drugs on the market but they put price tags on them that would bankrupt anyone without some sort of third party payer. The combination of all of these drugs make up what doctors

It is no secret that cancer is leading cause of death in the world. It was estimated that in 2012, 14.1 million new cases of cancer occurred worldwide and 8.2 million people died as a result of cancer [1]. Cancer prevalence is increasing at an alarming rate, yet the progress of treatment has been slow, with benefits of treatment being measured in only months or even weeks. Most patients with a specific type of cancer at a certain stage will receive the exact same form of treatment, but it has been made clear that while the treatment works well for some, it does not for a significant amount of others. The treatment that patients receive today is based on

These treatments include medications such as, immunosuppressive drugs, steroids, chemotherapy and anti-inflammatory drugs. In addition to medications, therapy and physical exercise can also contribute to decreasing the progression of the disease. Besides medical treatments, there are also a number of alternative methods for treatment, such as mineral supplements, acupuncture, massage and cannabis. Furthermore, clinical trials are also avenues for individuals to explore for treatment. Hematopoietic Stem Cell Transplantation (HSCT) is part of a clinical trial and can be used in conjunction with chemotherapy. An individual named Geoff Flynn traveled to Israel in 2015. Shortly after his treatments, he noticed a decrease in his symptoms and was significantly less fatigued (Fernandes, 2017). Although, his symptoms improved the HSCT treatment is still in a clinical trial period. In addition, the cost of the treatment is significant and most healthcare plans do not cover the cost. Although, aggressive treatments and early detection are key, despite these activities most long-term outcomes are often

Every year millions of people are being freshly diagnosed with cancer and a healthy amount is diagnosed with some form of myeloid leukaemia. Few decades ago treatment options for myeloid leukaemia were not so diverse and mortality rate amongst patients were very high. Things have changed dramatically due to the introduction of various treatment options; patients are being able to lead a healthy life prior to their medication period. Though conventional chemotherapy is still used but there are a variety of drugs that have been introduced which could replace chemotherapy and stem cell transplantation in near future as these new generation of drugs have a very specific mode of action and they have a minimal side effect. For example Tyrosine Kinase

The Novartis treatment’s basis is to provide a more permanent fix to fighting diseases through personalized cell treatment and immune system alterations. “Science has since come up with all manner of potions and procedures (from aspirin to organ transplants to bionic knees) to keep us from falling to pieces. But it turns out the body might be its own best pharmacy; each one of us possesses internal stores of life-extending remediation. Scientists are now learning to access those once locked and guarded in our warehouses to nudge us toward durability.” (Popular science magazine, Engber). The immune system is highly complex and formidably strong towards diseases. This gives scientists the idea that we should be helping our bodies fight the disease long term, rather than short-term use of conventional drugs and treatments. he Novartis treatment trains our T-cells (variations of white blood cells) to identify the differences in malignant cancer cells and attack them. The fact that the technology is“manufactured on an individual basis for each new patient from the patient's own T-cells” (Forbes, Herper) makes it stand out. This means, that the newly altered cells can stay in the body, and if the cancer decides to come back, they are there, specially trained to eliminate the cancer cells

Adoptive cell transfer (ACT) is an immunotherapeutic strategy that takes advantage of tumor antigen-specific CD8+ T cells within tumor infiltrating lymphocyte (TIL) populations. Preclinical and clinical studies have proven the principle of ACT immunotherapy, in which TIL are isolated from tumors, stimulated to undergo massive in vitro proliferation, and infused into patients in hopes of causing immunological tumor regression [1-3]. ACT protocols typically depend on pre-transfer lymphodepletion to maximize the engraftment and persistence of ex vivo-expanded T cell populations [4,6]. Although clinical trials of melanoma ACT have demonstrated favorable response rates and cases of profound and durable disease regression, suboptimal response

There are several treatments to combat cancers which can work well alone or in combination with sequentially or simultaneously. Of those treatments the most
