It's crucial to be well informed about the dangers of genetically engineered drug-based IMMUNOTHERAPIES...
A BEST survival strategy is being properly informed before committing to genetically engineered drug-based immunotherapies (immune therapy) therapies: Did you even know that the ‘new’ immunotherapies are genetically engineered & drug-based? And do you know there is a safer option?
Are you aware of...
*The potential severity of side effects – severe organ damage etc.
*The USA litigation cases re harm from many genetically engineered drug-based immunotherapies such as Keytruda.
Background: There is much excitement & euphoria in the media & medical journals about the new genetically engineered drug-based immunotherapies . Oncologists worldwide have been motivated the idea that these terapies could replace many chemotherapies & by convincing pharmaceutical company literature with stories of spectacular remissions.
SOME SIDE EFFECTS OF DRUG BASED IMMUNOTHERAPIES
While the euphoria continues to grip oncologists in Australia and New Zealand, the euphoric dust has settled in the USA & Europe where they are now treating these new drugs with CAUTION.
Warnings are appearing in the medical literature detailing severe & unpredictable side effects caused by genetically engineered drug based immune therapies. Deaths have been reported & long-term (unpredictable) side effects have been severe. Drs have been told to issue patients with medical alert cards in case they end up in intensive care or emergency wards.
A revealing CAR-T Cell Therapy story about horrific side effects from a doctor working at the front line of this new experimental treatment – Dr Ilana Yurkiewicz
“Cytokine release syndrome — occurs in more than half of patients who receive CAR-T, starting with Ludwig and Whitehead. The syndrome is the collateral damage of an immune system on the highest possible alert. This was first seen with other types of immunotherapy, but CAR-T took its severity to a new level. Usually starting the week after CAR-T, cytokine release syndrome can range from simple fevers to multi-organ failure affecting the liver, kidneys, heart, and more. The activated T-cells make and recruit other immune players called cytokines to join in the fight. Cytokines then recruit more immune cells. Unlike in the early trials at Penn, we now have two medicines to dampen the effect. Steroids calm the immune system in general, while a medication called tocilizumab, used to treat autoimmune disorders such as rheumatoid arthritis, blocks cytokines specifically.”
“The second side effect was even scarier: Patients stopped talking. Some, like Sharon Birzer spoke gibberish or had violent seizures. Some couldn’t interact at all, unable to follow simple commands like “squeeze my fingers.” How? Why? At hospitals across the nation, perfectly cognitively intact people who had signed up to treat their cancer were unable to ask what was happening.
Our nurses learned to ask a standardized list of questions to catch the effect, which we called neurotoxicity: Where are we? Who is the president? What is 100 minus 10? When the patients scored too low on these quizzes, they called me to the bedside.”
WHY IT IS CRUCIAL TO BE INFORMED!
We know that cancer patients are interested in the most effective & most minimally invasive cancer treatments. BUT knowledge and a dash of caution is required before considering taking treatment with a drug-based immune therapy.
While there have been both short and long-term successes in treating melanomas; some kidney cancers & some lung cancers; it is important patients are aware of the risks.
The most common procedure for CAR-T cell therapy starts with the extraction of T cells from the own patient. The T cells are then genetically modified to express a CAR and expanded in the Laboratory.
Finally, they are re-infused into the patient, ready to fight the tumour. Unlike the unblocking effect of the immune system to find and destroy cancers; immunotherapies based on CAR-T cells go one step further by engineering the T cells themselves to enhance the response from the immune system against a specific tumour antigen.
The flip side of the benefit of drug-based immunotherapy, which is a long-term response against the cancer, is that toxicities can happen at the beginning of treatment or long after their last dose.” (GGI Note: up to 4 years later) Sandip P. Patel, MD (ASCO Post – American Society of Clinical Oncology)

NO MORE GUESSWORK: A BRILLIANT NEW GENOMIC TEST CAN GAUGE YOUR SUITABILITY FOR A DRUG-BASED IMMUNOTHERAPY - NO MORE NEED TO SUFFER WITHOUT GAIN - READ ON
BE INFORMED- DO KNOW THERE IS A NEW TEST THAT ELIMINATES GUESSWORK (& ANXIETY):
There is a now test for measuring your suitability for drug based immune therapies: Most patients are not informed that the test; Tumour Mutational Load (TML) – is available & performed at genomic diagnostic laboratories.
This test can give patients and their oncologists a particular measurement, that indicates whether or not a drug based immune therapy will work for you (popularly known as anti-PD1 immune therapy).
SADLY: It is unlikely the test will be offered to you by hospitals in AU & NZ.
We are playing with fire,” said Dr. John Timmerman, an oncologist and immunotherapy researcher at the University of California, Los Angeles, who recently lost a patient to side effects.
The woman’s immunotherapy drugs had successfully “melted away” her cancer, he said, but some weeks later, she got cold and flulike symptoms and died in the emergency room from an inflammatory response.
Dr. Timmerman described it as “a mass riot, an uprising” of her immune system – Immune System, Unleashed by Cancer Therapies, Can Attack Organs

Patients treated for skin or lung cancer cancer using newer, potent immunotherapies appeared to be at an increased risk of developing thyroid-related adverse events, researchers reported here. Of 93 patients treated with pembrolizumab (Keytruda), 14 developed thyroid dysfunction. These drugs release the brakes on the immune system, and by releasing those brakes, of course, you can get autoimmune diseases. It can cause problems with the colon; it can be the liver; it can be the thyroid.”
Cabanillas said that the Mayo researchers are reporting on thyroiditis with pembrolizumab “which is usually what we see with this class of checkpoint inhibitors but there are other types of checkpoint inhibitors, such as ipilimumab, [that]…cause more pituitary adverse events.” Solid Tumor Immunotherapy May Impact Thyroid
Despite the optimism, though, it’s important to know that CAR T-cell therapy has significant downsides: It’s not available to most patients, its approvals have strict limitations, and it often triggers serious side effects in some patients. Five things you should know about CAR T-cell therapy
Cancer Treatment Centres of America, (CTCA), March 20, 2018
Immune-based therapies in oncology present challenges in recognising & managing treatment-related toxic effects. Although many oncologists know of their adverse-effect profile, treatment remains limited to specialised centres with experienced & highly-skilled clinical care teams, capable of providing the supportive care required for patients undergoing such therapy, owing to the risk of severe hypotension and organ failure during treatment. Managing the Side Effects of Novel Cancer Immunotherapeutics
The toxicities of immunotherapy for cancer are as diverse as the type of treatments that have been devised. These range from cytokine therapies that induce capillary leakage to vaccines associated with low levels of autoimmunity to cell therapies that can induce damaging cross-reactivity with normal tissue to checkpoint protein inhibitors that induce immune-related adverse events that are autoinflammatory in nature.

During the last years several cases of fatal heart failure have been documented in melanoma patients treated with checkpoint inhibitors. Checkpoint Inhibitors & Cardiac Toxicity: An Emerging Issue
ASCO – Although (drug-based) immunotherapies can be effective in boosting the body’s natural defence against cancer in some patients, providing durable remissions in a small percentage of cases, they can also result in myriad immune-related adverse events due to misdirected stimulation of the immune system. E.G. only a small percentage of patients—between 15% and 20%—receive some benefit from checkpoint inhibitors that target CTLA-4 or the PD-1 and PD-L1 pathways for the majority of tumor types. They can also cause immune-related adverse events in which the immune system starts attacking normal tissue – some patients experience the side effects and none of the benefit.

Cytokine release syndrome (CRS) The hallmark of CRS is immune activation resulting in elevated inflammatory cytokines. Clinical and laboratory measures range from mild CRS (constitutional symptoms and/or grade-2 organ toxicity) to severe CRS (sCRS; grade ≥3 organ toxicity, aggressive clinical intervention, and/or potentially life threatening). Clinical features include: high fever, malaise, fatigue, myalgia, nausea, anorexia, tachycardia/hypotension, capillary leak, cardiac dysfunction, renal impairment, hepatic failure, and disseminated intravascular coagulation – often requiring treatment in ICU… Toxicities of CAR T-Cell Therapy
Financial Costs of Drug Based Immune Therapies
According to a research letter published in JAMA Oncology, patients treated with CAR T-cell therapy will incur on average $30,000 to $36,000 (USD) in additional costs aside from drug expenses. (e.g. $500/dose)
Patients who present with side effects from severe cytokine release syndrome may pay up to $56,000 (USD) more.
