Face-to-Face Communication Essay
Point 3: Do you concur or differ with the accompanying proclamation? Eye to eye correspondence is superior to different kinds of correspondence, for example, letters, email, or calls. Utilize explicit reasons and subtleties to help your answer. Various types of correspondence have been grown these days and they make it extremely simple for individuals to contact with one another. We have gotten comfortable with mainstream sorts of correspondence, for example, letters, email, calls or visiting on the web. Anyway a few people say that up close and personal talk is superior to different methods for correspondence. As I would like to think, I can't help contradicting this feeling. Because of the restriction of separation, up close and personal correspondence shows its impediments in a ton of circumstances. We can't meet and have a talk on the off chance that we are far away from one another like in various nations or various zones. It is extremely upsetting when we have to stand up something quickly or we are in a dire circumstance. Eye to eye talk truly takes a lot of time and cash if individuals are too far off. Additionally, in the quick pace of life, everybody is extremely occupied with their own work. They need to manage heaps of work and contact with a few dozen individuals. Subsequently, it is hard for them to consistently plunk down in a pleasant spot and converse with one another in light of the fact that it constrains their degree of work efficiency. Aside from separation and time, different kinds of correspondence exceed eye to eye talk regarding comfort and mystery. You can email to many individuals in various nations with just a single tick. You need to impart your joy to your companions and family members, simply get your telephone and consider them without heading over to make a declaration. At the point when you begin to look all starry eyed at and think that its hard to communicate your energy straightforwardly, at that point an affection letter to that individual will be a correct decision. With the solace of utilizing the web, we effectively make companions without being stressed over our appearances. Notwithstanding the way that we are fat or meager, pretty or terrible, perfect or careless, we despite everything have incredible talks in light of the fact that nobody sees us right at that point. All in all, up close and personal is only one type of correspondence among others. Each of those has its own points of interest and drawbacks and it is hard to state which one is better.

The Vietnam Conflict And Its Effects Essays - Vietnam War
The Vietnam Conflict and its Effects The Vietnam struggle started in the late nineteenth century. The French vanquished Vietnam and made it a protectorate. For almost forty a long time, Vietnam had not experienced settled harmony. The League for the Freedom of Vietnam ( Viet Minh ) was shaped in 1941, looking for freedom from the French. On September 2nd,1945, Ho Chi Minh declared it free of France. The French contradicted their freedom from 1945 to 1954. The principal agents of de Gualle's administration arrived by parachute in Saigon and Hanoi on August 23rd, 1945. The French needed to restore their standard in Vietnam yet were beaten at the skirmish of Dien Bien Phu on May seventh, 1954. The French Expeditionary Force attempted to forestall the Viet Minh from entering Laos and Dien Bien Phu was the spot picked to do as such. The French were not cautious and this permitted the Viet Minh to cut off their aviation route to Hanoi. After an attack that had gone on for fifty - five days, the French gave up. Ho Chi Minh drove the war against France also, won. After the war there was a meeting in Geneva where Vietnam was separated into two sections along the seventeenth equal. North Vietnam was essentially Communist and bolstered Ho Chi Minh, while the south was upheld by the United States and the French were based there. There was still some Communist agitators inside South Vietnam. These were the Viet Cong. The South Vietnam ruler was Ngo Dinh Diem who was hostile to - Socialist. At the meeting, Laos and Cambodia got autonomous states. North Vietnam wished to bring together North and South Vietnam through military power. Since the United States dreaded the spread of socialism in Asia, John F. Kennedy gave financial and military guide to South Vietman to forestall the takeover by North Vietnam. As of now, this was as yet a common war. The United States were not yet formally included. The North Vietnamese disliked the little intercession by the Joined Sates thus, three Vietnamese torpedo pontoons terminated on the U.S. destroyer, Maddox on August second, 1964. The Maddox had been in the Gulf of Tonkin ( worldwide waters ), thirty miles off the bank of Vietnam. On August third, 1964, Johnson gave the privilege to assault with the goal of wrecking assaulting powers ( Pimlott 1982, 36 ). Counter air assaults started on August third. Their point was to wreck North Vietnam's gunboat ability. As two increasingly United States destroyers were as far as anyone knows sunk, more air and ocean powers were sent ( Wicker August 5, 1964, 1 ). As of recently, the U.S. had avoided direct battle. This is the point at which the United States officially entered the Vietman War. The U.S. did this for two reasons. We wished to keep up the freedom of South Vietnam and we needed to demonstrate to united countries that we would assist them with opposing Communist overwhelming. As Congress was going to cast a ballot whether to permit the battle to move into North Vietnam, the North Vietnamese assaulted a significant U.S. airbase at Bein Hoa. On February seventh, 1965, Johnson requested reprisal shelling on North Vietnam. Moving Thunder was the name of this activity. It's motivation was to squeezed Hanoi and persuade them that Communism couldn't and would not win. Toward the finish of 1965, one hundred and eighty thousand Americans were in South Vietnam under General William S. Westmoreland (Reference book Britannica, 12, 361 ). The U.S. primarily relied upon predominant capability and helicopters. The Viet Cong and North Vietnamese relied upon shock assault and camouflage. The United States fighters understood that the war would keep going for a lot more years and thought about whether the U.S. war exertion could succeed. At the finish of 1968, The quantity of American soldiers in South Vietnam arrived at it's pinnacle of 542, 000 men ( Pimlott 1982, 53 ). The Viet Cong what's more, North Vietnamese propelled a significant attack against the United States called the Tet hostile from January 30th to February 25th, 1968.

Treatment of Solid Tumors including Metastatic Breast Cancer - Free Essay Example
Citizen Petition Reconsider Issuance of RMAT Designation for Therapeutic Armed Activated T Lymphocytes Treatment of Solid Tumors including Metastatic Breast Cancer The undersigned submits this petition under to request the Commissioner of Food and Drugs to reconsider issuing a Regenerative Medicine Advanced Therapy (RMAT) designation to autologous T-lymphocyte therapies for patients with malignant advanced stage solid tumors, specifically stage IV metastatic breast cancer, on the basis that it can meet an unmet medical need as substantiated by new clinical trial evidence resulting from trial involving OKT3 x Herceptin Armed Activated T Cells, Low Dose IL-2, and GM-CSF, as relevant to section 506(g) of the Federal Food, Drug, and Cosmetic Act (FDC Act), as added by section 3033 of the 21st Century Cures Act (Cures Act). A. Action Requested The Expedited Programs for Regenerative Medicine Therapies for Serious Conditions Draft Guidance for Industry states that in order for an investigational drug to receive a Regenerative Medicine Advanced Therapy (RMAT) designation it must fulfill the following criteria1:. It meets the definition of regenerative medicine therapy (see section I of [draft guidance] document) It is intended to treat, modify, reverse or cure a serious condition; and Preliminary clinical evidence indicates that the regenerative medicine therapy has the potential to address unmet medical needs for such condition The Expedited Programs for Regenerative Medicine Therapies for Serious Conditions Draft Guidance for Industry states that the definition of regenerative medicine therapy is1: â⬠¢ Cell therapies, therapeutic tissue engineering products, human cell, and tissue products, and combination products using any such therapies or product And Gene therapies, including genetically modified cells, that lead to a durable modification of cells or tissues may meet the definition of a regenerative medicine therapy. In said draft guidance, unmet medical need is defined as: â⬠¢ An unmet medical need is a condition whose treatment or diagnosis is not addressed adequately by available therapy. An unmet medical need includes an immediate need for a defined population (i.e., to treat a serious condition with no or limited treatment) or a longer-term need for society (e.g., to address the development of resistance to antibacterial drugs). We, the undersigned, petition the Commissioner of Food and Drugs to reconsider issuing an RMAT designation to autologous T-Lymphocyte therapies for solid tumors, and we offer new clinical trial data from the trial named Treatment of Stage IV Breast Cancer With OKT3 x Herceptin Armed Activated T Cells, Low Dose IL-2, And GM-CSF (NCT00027807) as clinical evidence that indicates the potential to meet an unmet medical need thereby fulfilling the requirement ââ¬Å"that the regenerative medicine therapy has the potential to address unmet medical needs for such conditionâ⬠listed in The Expedited Programs for Regenerative Medicine Therapies for Serious Conditions Draft Guidance for Industry.1 B. Statement of Grounds Cancer is the second leading cause of death in the United States, with breast cancer following lung cancer as cancers with the highest mortality rates. While there have been a number of cancer therapies found to either treat or cure early-stage cancers, late-stage solid t umors tend to elude these therapies, and as a result, there are very few therapies that can attempt to treat them. Breast cancer is a disease that affects 1 out of 8 women, with 10% of all cases eventually metastasizing 5 years after the patient has received therapy for it.2,3 Many patients receive a form of therapy for breast cancer that may involve surgery with adjuvant chemotherapy, or even in the case of high-risk breast cancer high-dose chemotherapy with a stem cell transplant. Unfortunately, relapse rates after these therapies remain high, and often times the cancer has metastasized at that point. 55-87% of women who have primary breast cancer with 10 or more axillary lymph nodes relapse within 5 years of when they were diagnosed. 4 Stage IV metastatic breast cancer represents an unmet medical need, as it is not being met by current treatments or therapies. Additionally, there is research that indicates that combination therapies would work in a more effective manner against metastatic breast cancer than a single therapy.4 Some of the therapies that are currently being considered in clinical trials involve chimeric T cells, others are looking at armed activated T cells (aATC), and others are considering antibodies.3,4 The trial in question that we are using as the basis for our petition analyzes the combination immunotherapy consisting of HER2Bi armed activated T cell infusions, IL-2, and GM-CSF.3,4 The HER2Bi or BsAb consists of two monoclonal antibodies that were heteroconjugated and used to arm the T cells. These two monoclonal antibodies were Trastuzumab (Herceptin, Genentech) and an anti-CD3 (OKT3, Centocor, Ortho-Biotech) that were prepared under Current Good Manufacturing Practice (cGMP) regulations as enforced by the Food and Drugs Administration.5 Trastuzumab or the brand name Herceptin has been approved for use in the treatment of breast cancers that overexpress the HER2/neu receptor, which is a tyrosine kinase transmembrane epidermal growth factor receptor family member.3 The HER2/neu receptor is overexpressed in many breast, ovarian, gastric, lung, prostate and oral cancers. This overexpression of HER2/neu makes it an ideal therapeutic target. 3,4 Moreover, women with HER2- cancers have fewer therapeutic options, but the trial demonstrated a positive result in those patients as well, which further supports the claim that this therapy can fulfill an unmet need for a serious condition. The OKT3 or anti-CD3 antibody targets the CD3 T cell receptor. Together they form the HER2 Bispecific antibody (HER2Bi), which is engineered to direct cytotoxicity at tumor cells that overexpress the HER2/neu receptor. In this trial, they combined the HER2Bi with Interleukin-2 and the granulocyte macrophage colony-stimulating factor (GM-CSF). Interleukin-2 is a cytokine produced by leukocytes, which increases the growth and activity of other T lymphocytes and B-lymphocytes, as well as affecting the development of the immune system. GM-CSF is another cytokine that helps create additional white blood cells specifically granulocytes, macrophages, and cells that become platelets.3 The primary endpoints of the trial were to determine the safety and maximum tolerated dose. The highest dose that was administered consisted of 20 x 10^9 aATC, and the maximum tolerated dose level was not reached, nor were there any dose-limiting toxicities observed at this dosage level. The secondary endpoints of the study were assessments of response rates: complete response (CR), stable disease (SD), partial response (PR), and no evidence of disease (NED), time to progression (TTP), and overall survival (OS). TTP and OS were measured from the date of enrollment in the trial.3 The study consisted of 23 women with stage IV metastatic breast cancer, of both HER2+ and HER2- patients, in a traditional 3+3 dose escalation design. One patient in the study died from digoxin toxicity related congestive heart failure, and the autopsy of the patient did not show any myocardial T cell infiltrates. The remaining 22 patients were evaluated at 14.5 weeks. Results showed 59.1% (13/22) of patients had SD or better (NED, PR, or SD) and 40.9% (9/22) of patients had PD. The overall survival rate of the 22 evaluable patients was 36.2 months. Within the overall survival rate, the breakdown was an overall survival rate of 57.4 months for HER2+ and 27.4 months for HER2-. The results of t his study showed that there were no major negative side effects associated with this aATC therapy. There were no cytokine storms, which has been a problematic side effect in past T-cell therapies, but there were however what the researchers designated cytokine flurries.3 And while a number of patients had to have their aATC washed to reduce side effects, not a single patient had to have their dose lowered. The main side effects observed were grade 3 chills and grade 3 headaches. The incidence of chills was 8.6%, 20.8%, and 43.1% at dose levels 1, 2, and 3, respectively. The incidence of headaches was 3.1%, 8.3%, and 19.6% at dose levels, 1, 2, and 3. Two patients were hospitalized to manage other side effects that included nausea, hypotension, vomiting, and dehydration, but after the successful resolution of these side effects they resumed the trial and continued to receive the infusions of the aATCs. In this trial, the innate cytotoxicity of T cells was redirected by the formation of the aATC (can be prepared with either CD4+ or CD8+,). Normal patients and cancer patients who rec eived this combination therapy of aATC with HER2Bi combined with IL-2 and GM-CSF both exhibited specific cytotoxicity towards target cells, and the cytotoxicity increased as the dosage amount of the aATC increased. 4 The cytotoxicity persisted for more than 54 hours towards the target cells, and other cytokines including IFN-?, TNF- ?, and GM-CSF were induced when the tumor antigen was bound to the aATC.4 This capability of the aATC to induce IFN-? when it binds to a tumor antigen may be clinically beneficial, as other studies have already shown in preclinical and clinical studies that cytotoxic T cells produce IFN-? and that IFN-? is tumoricidal.6,7 Another advantage of this particular therapy is that it does not require large quantities of HER2Bi unlike other infusional therapies that do require large doses of bispecific antibodies. In fact, billions of armed activated T cells can be armed with just milligrams of the HER2Bi antibody. The aATCs proved to be cytotoxic even towards breast cancers that had a low expression level of HER2 receptors, such as the MCF-7 breast cancer cell line. 4 The SK-BR-3 cell line, which has higher levels of HER2 receptors, had even more susceptibility to cytotoxic effects from the aATC, causing greater amounts of tumor cells to be lysed.4 This indicates that even a small amount of the combination of the anti-CD3 and anti-HER2 antibodies that are used to arm activated T cells can mediate high levels of cytotoxicity that is directed at tumor cells. Even when the levels of the tumor antigen expression is low as in the case of the MCF-7 cell line, and are able to mediate cytotoxicity in vivo for many days after infusion of the aATCs.4 The fact that that the maximum tolerated dose was not reached, that there were no dose-limiting toxicities, nor was there any evidence of a life-threatening cytokine storm, and all other side effects were relatively mild and successfully resolved supports the idea that multiple infusions of aATC in combination with IL-2 and GM-CSF were both safe and technically feasible. The results of this study showed that combining antibody targeting and T cell-mediated killing could greatly augment cytotoxicity that can be directed towards cancer cells and provides a rationale to develop new nontoxic immunological approaches that can eradicate any residual tumor cells. 4 Ultimately the researchers have concluded that multiple intravenous infusions of the HER2Bi aATC are feasible, and most of them would go to the lungs and then migrate to, and settle, in the spleen, bone marrow, and liver. This is advantageous because many breast cancers metastasize to these locations, which would make the targeting of these metastases by the aATC easier. The authors of this study had intended on moving forward with a Phase II trial, and the results supported the rationale for moving forward. However, this trial ultimately did not move forward to a Phase II trial, but it did provide the rationale for further clinical trials on similar immunotherapies. A separate trial studied the HER2Bi armed activated T cells in HER2+ colorectal cancer, both in vitro and in vivo. The aATC exhibited increased cytotoxicity against HER2+ tumor cells, and showed significant suppression of colorectal carcinoma cells in comparison to unarmed ATC. Similar to the above-mentioned breast can cer trial, researchers were able to reach these results by using a very low dose of HER2Bi, which eliminated previously seen side effects of Herceptin which included cardiotoxicity that manifested as left ventricular dysfunction and heart failure in a different research project. 8 Much like the trial conducted on metastatic breast cancer, the data in this trial also showed that aATC induced IFN-? secretion levels that were higher than those induced by unarmed ATC, As such the researchers of this trial concluded that ââ¬Å"HER2Bi?armed ATCs with anti?tumor effects may provide a promising immunotherapy for colorectal carcinoma for the futureâ⬠.9 Another Phase I trial examined the HER2Bi aATC in metastatic castrate-resistant prostate cancer. They also found an increased level of IFN-? as well as no dose-limiting toxicities that were associated with this immunotherapy. 3 out of 7 patients in this trial showed a decrease in their prostate-specific antigen (PSA) and pain levels. The results of this trial provided strong rationale to continue onto a Phase II trial.10 Furthermore, there is another trial in progress that is also researching HER2Bi armed activated T cells combined with pembrolizumab, which blocks the PD-1 pathway, in patients with metastatic bre ast cancer. The trial (NCT03272334), sponsored by the University of Virginia is currently recruiting patients, but we look forward to seeing if it reaches its primary endpoints, which are evaluating the side effects and best dose for this treatment without reaching any dose-limiting toxicities. 11 While we need to keep a watchful eye on more severe side effects such as the possibility of life-threatening cytokine storms in future trials, the fact that the trial on metastatic breast cancer only had cytokine flurries is an encouraging sign. Novel immunotherapies including T-cell therapies are making headway as therapeutics for solid tumors and is a field that holds great promise because it can boost patients preexisting tumors responses, in a nontoxic manner, specifically in tumors that have no current successful therapy options.12 We would request that the Commissioner of Food and Drugs reconsider issuing an RMAT designation to autologous T-Lymphocyte therapies for solid tumors based on the preclinical trial data as covered above from the trial Treatment of Stage IV Breast Cancer With OKT3 x Herceptin Armed Activated T Cells, Low Dose IL-2, And GM-CSF (NCT00027807). We feel that this data, along with the fact that metastatic breast cancer is a serious condition that has very few therapies available to treat, and as such is an unmet medical need, fulfills all the requirements of an RMAT designation which are listed as: It meets the definition of regenerative medicine therapy (see section I of [draft guidance] document) It is intended to treat, modify, reverse or cure a serious condition; and Preliminary clinical evidence indicates that the regenerative medicine therapy has the potential to address unmet medical needs for such condition C. Environmental Impact The petitioner hereby states that the action requested in this petition will have no environmental impact and that, therefore, an environmental assessment is not required under 21 CFR 25.30. D. Economic Impact Not applicable; this section has not been requested by the Commissioner. E. Certification The undersigned certifies, that, to the best knowledge and belief of the undersigned, this petition includes all information and views on which the petition relies, and that it includes representative data and information known to the petitioner which are unfavorable to the petition.
