What Are The Side Effects Of Cancer Treatment Vaccines

FDA approves vaccine to treat prostate cancer

Cancer treatment vaccines can cause side effects, which affect people in different ways. The side effects you may have and how they make you feel will depend on how healthy you are before treatment, your type of cancer, how advanced it is, the type of treatment vaccine you are getting, and the dose.

Doctors and nurses cannot know for sure when or if side effects will occur or how serious they will be. So, it is important to know which signs to look for and what to do if you start to have problems.

Cancer treatment vaccines can cause flu-like symptoms, which include:

Personalized Clinical Trials For Prostate Cancer

Research is uncovering more information about the genetic changes that happen as prostate cancers develop and progress. Although early-stage prostate cancer has relatively few genetic changes compared with other types of cancer, researchers have learned that metastatic prostate cancers usually accumulate more mutations as they spread through the body.

These mutations may make men with metastatic prostate cancers candidates for what are called basket clinical trials of new drugs. Such trials enroll participants based on the mutations found in their cancer, not where in the body the cancer arose. In the NCI-MATCH trial, a high percentage of enrolled men with advanced prostate cancer had mutations that could potentially be targeted with investigational drugs.

When Can I Have The Vaccine

The vaccine is being offered to people based on their risk from coronavirus. Over time, more and more people will be invited to have the vaccine.

You can read more about the priority groups, who is currently eligible for the vaccine, and how to book an appointment for the vaccine on the relevant NHS website for England, Scotland or Wales, or the HSC website for Northern Ireland.

The Cancer Vaccine That Could Prevent Prostate Cancer

Harnessing the immune system could offer an entirely new way to stop prostate cancer, and our research is creating the technology to do it.

Vaccines everyones talking about them, but did you know its not just viruses that we can vaccinate against? Were supporting researchers who are developing a vaccine for prostate cancer that could treat men with prostate cancer and even prevent them getting the disease in the first place.

Please note this research project is still in the early stages. We hope the vaccine reaches clinical trials and if so, we’ll let our supporters know right away.

Alicia Morgans: Hi, my name is Alicia Morgans and I’m a GU Medical Oncologist at Dana-Farber Cancer Institute. I’m so excited to have here with me today, a good friend and colleague, Dr. Ravi Madan, who is the Clinical Director of the GU Malignancies branch of the Center for Cancer Research, National Cancer Institute in Bethesda. Thank you so much for being here with me today, Dr. Madan.

Ravi Madan: Thank you, Dr. Morgans, for that kind introduction.

Alicia Morgans: Of course. Ravi, I wanted to talk with you about some work that you and the team presented at ESMO 2021, really looking into sodium fluoride PET imaging in patients who were getting enzalutamide and PROSTVAC. Can you tell us a little bit about this study and what you presented?

Alicia Morgans: I think that’s really such an interesting concept, and even might be something that we would love to hear about just in terms of general PET imaging, because that’s not something that we have typically for our patients with prostate cancer. Can you tell us a little bit about what you found and what you’re thinking about the data?

Alicia Morgans: Can you tell us, Dr. Madan, how did these changes correlate with PSA? Or do you have that information?

Life Styles That Can Increase The Risk Of Prostate Cancer

  • Smoking: Males who habitually smoke have a higher risk of developing prostate cancer.
  • Eating Habits: Eating foods that are rich in heterocyclic amines can cause prostate cancer, heterocyclic amines are carcinogenic in nature. These are found mainly in red meats.
  • Unprotected sex or having many sexual partners: can cause sexually transmitted diseases such as chlamydia and gonorrhoea. Chlamydia and gonorrhoea cause prostatitis and if prostatitis is left untreated for a long time can cause prostate cancer.

Ive Already Had A Flu Jab Do I Still Need The Covid

The flu jab doesnt protect against coronavirus. To protect yourself against the flu and coronavirus, you need to have both the flu vaccine and the new COVID-19 vaccine.

You wont be able to have the flu and COVID-19 vaccines at the same appointment youll need to leave at least a week in-between, to ensure they both work properly.

A Trial Of A Vaccine Treatment For Prostate Cancer That Has Come Back

Cancer type:

Phase:

This trial looked to see if a vaccine could stimulate the immune system to help treat prostate cancer that has come back. This trial was supported by Cancer Research UK.

Doctors usually treat prostate cancer with surgery, radiotherapy or hormone therapy. But sometimes the cancer continues to grow despite treatment. This trial looked at a type of vaccine treatment called a DNA vaccine for people who had already had other standard treatments.

Immune system cells can seek out and kill cancer cells, but they often dont do this very well. Vaccines can help the immune system to do this. The vaccine in this trial helps cells in the immune system to spot a substance made by some prostate cancer cells called prostate specific membrane antigen .

The trial looked at 2 ways of giving the vaccine. One was by injection into a muscle. The other was by injection into a muscle but with a short electrical pulse at the same time.

The aims of this trial were to find out

  • If this DNA vaccine stimulates the immune system

Blood Derived Dc Vaccines

Advances in efficiency of isolation protocols allow the use of blood DC as an alternative to MoDC or DC enriched preparations . Prue et al. in a phase I trial showed that it was feasible to isolate CD1c+ DC from CRPCa patients via magnetic separation and vaccination, was well-tolerated with fever and pain the most common toxicity . More recently, in a phase II RCT Westdorp compared the efficacy of matured myeloid DC vs. plasmacytoid DC vs. combination of mDC and pDC . Again, this showed that blood derived DC were safe and induced an immune response, with a trend to a better response with mDC alone. These technical advances in isolating DC as a pure population and, as demonstrated by Westdorp et al. isolating specific DC subsets and utilize the underlying specialization of human DC to take up antigen allows us to direct the immune response in a particular direction.

A Trial Of A Vaccine Called Prostvac For Prostate Cancer

Please note – this trial is no longer recruiting patients. We hope to add results when they are available.

Phase:

This trial is looking at a new vaccine called PROSTVAC for prostate cancer that has spread.

If prostate cancer has spread outside the prostate gland, doctors often treat it with hormone therapy. This can work very well, but at some stage the cancer may start to grow again. This may not cause symptoms, but your doctor might see changes on a scan or there may be an increase in the level of PSA in your blood.

The immune system can recognise and kill cancer cells. But it is not always very good at doing this. In this trial, researchers are looking at a vaccine called PROSTVAC that can help the immune system to recognise and attack prostate cancer cells.

GM-CSF is a type of growth factor. Growth factors are proteins made in the body and some of them make the bone marrow produce blood cells. GM-CSF makes the body produce white blood cells. The researchers want to find out if giving GM-CSF alongside the vaccine can help it to work better.

The men taking part in this trial have prostate cancer that scans or blood tests show is getting worse. But their cancer is not causing symptoms or only causing very mild symptoms. The researchers will compare men in 3 groups

  • PROSTVAC alongside GM-CSF
  • PROSTVAC alongside a dummy drug
  • PROSTVAC dummy drug alongside GM-CSF dummy drug

Improving Biopsies For Prostate Cancer

Traditionally, prostate cancer has been diagnosed using needles inserted into the prostate gland in several places under the guidance of transrectal ultrasound imaging to collect samples of tissue. This approach is called systematic biopsy.

However, ultrasound does not generally show the location of cancer within the prostate. It is mainly used to make sure the biopsy needles go into the gland safely. Therefore, biopsy samples using ultrasound guidance can miss cancer altogether, or identify low-grade cancer while missing areas of high-grade, potentially more aggressive cancers.

Some doctors, concerned that a systematic biopsy showing only low-grade cancer could have missed a high-grade cancer, may suggest surgery or radiation. However these treatments are for a cancer that may have never caused a problem, which is considered overtreatment.

Using MRI and ultrasound. Scientists at NCI have developed a procedure that combines magnetic resonance imaging with TRUS for more accurate prostate biopsies. MRI can locate potential areas of cancer within the gland but is not practical for real-time imaging to guide a prostate biopsy. The new procedure, known as MRI-targeted biopsy, uses computers to fuse an MRI image with an ultrasound image. This lets doctors use ultrasound guidance to biopsy areas of possible cancer seen on MRI.

Prostate Cancer: Focus on Therapeutic Vaccines

Previously, patients could only undergo this treatment at their own expense in Germany. Jan-Paul Esser is a nuclear medicine doctor in Meander and is very proud that the hospital can now apply this treatment itself: The future of nuclear medicine is therapy. As the second hospital in the Netherlands, we can and may offer this new therapy on a regular basis. We are extremely proud that we have succeeded in this, in close cooperation with the pharmacy and clinical physics. With this Lutetium-177-PSMA treatment, quality of life can be gained and survival is gained.

In Vitro Culture Of Pbmcs And Tumor

PBMCs and TILs were cultured in vitro to expand 5T4-specific T cells. Briefly, 3×106 freshly isolated PBMCs/mL was plated in complete medium with or without total 5T4 peptide pool in the presence of recombinant human IL-7 . Every 34 days, the medium was replaced and rhIL-2 added to the cultures. PBMCs were harvested after 2 weeks and incubated overnight at 37°C before further analysis. To obtain TIL cultures, prostate tissue specimens were cut into small pieces and cultured in the presence of rhIL-2 as described previously. TIL medium was replaced every 23 days and the total 5T4 peptide pool was added when immune cell cultures entered an exponential growth phase. TILs were typically harvested 1week post-5T4 stimulation for further analysis.

  • Study Details

This study will evaluate the side effects of a fixed dose of vaccine and GM-CSF with increasing doses of anti-CTLA-4 antibody in patients with advanced prostate cancer. The vaccine consists of a “priming vaccine” called PROSTVAC/TRICOM, made from vaccinia virus, and a “boosting vaccine” called PROSTVAC-F/TRICOM, made from fowlpox virus. GM-CSF is a chemical that boosts the immune system, and anti-CTLA-4 antibody is a protein that may improve anti-tumor activity and the response to the vaccines. DNA is inserted into the priming and boosting vaccine viruses to cause production of proteins that enhance immune activity and also to produce prostate specific antigen -a protein that is normally produced by the patient’s tumor cells.

Patients are monitored for safety and treatment response with the following tests and procedures:

Immunotherapy: Checkpoint Inhibitors For Prostate Cancer

An immune checkpoint inhibitor is a type of drug that blocks proteins on the immune cells, making the immune system more effective at killing cancer cells.

A checkpoint inhibitor called pembrolizumab has been approved for the treatment of tumors, including prostate cancers, that have specific genetic features. Pembrolizumab has also been approved for any tumor that has metastasized and has a high number of genetic mutations.

But relatively few prostate cancers have these features, and prostate cancer in general has largely been resistant to treatment with checkpoint inhibitors and other immunotherapies, such as CAR T-cell therapy.

Research is ongoing to find ways to help the immune system recognize prostate tumors and help immune cells penetrate prostate tumor tissue. Studies are looking at whether combinations of immunotherapy drugs, or immunotherapy drugs given with other types of treatment, may be more effective in treating prostate cancer than single immunotherapies alone.

How The Vaccine Works

Prostate Cancer and Immunotherapy with Dr. Ana Aparicio

This vaccine has to be made especially for each man who gets it. Immune cells are taken from the man’s blood and sent to a lab. These immune cells are then exposed to a protein found on prostate cancer cells. At the same time, they are exposed to a chemical to boost the immune response. This helps the immune cells recognize and attack prostate cancer cells. They are then put back into the mans body, such as into a vein. Once back in the body, these cells help other immune cells attack the prostate cancer.

Developing A Cancer Vaccine

One particularly exciting project weve funded is a prostate cancer vaccine being developed by Professor Helen McCarthy at Queens University Belfast.

The vaccine works by carefully packaging genetic material from prostate cancer cells, called mRNA , and delivering it directly to the immune system. The mRNA is part of the genetic information of the cancer cells and, although it isnt dangerous, its enough to train the immune system to recognise and attack prostate cancer cells. Professor McCarthys research aims to offer a treatment for men with advanced prostate cancer who currently have very few options available. At that stage, the cancer is often incurable and a prostate cancer vaccine could be the much-needed revolution in treatment to give these men more time with their loved ones.

Delivering the cancer vaccine Professor McCarthy and her team are not only developing the prostate cancer vaccine, theyre also exploring new techniques so that it gets to the right cells in the body. The mRNA breaks down easily, so they have created a protein parcel that carefully packages the mRNA and lets it reach the immune cells intact.

Its the combination of an excellent vaccine and innovative delivery method that makes Professor McCarthys work so important. In her words, You can make the best treatment in the world, but if it cant get where it needs to go, its useless.

Health & Wellbeingaustralians Are ‘slacking Off’ On Social Distancing

Dr Roberts added that hes excited about the vaccines potential and needs $500,000 in funding to fast-track the research.

Immunotherapy for prostate cancer research aims to cure what is currently an incurable cancer and provide a non-invasive treatment with minimal side effects for the patient, he said.

The therapeutic vaccine has the potential to dramatically improve the quality of life for patients and help them live longer.

The RBWH Foundation has launched a fundraising campaign for the research called Donate for Prostate, coinciding with International Prostate Cancer Awareness Month and Fathers Day.

Targeted Radiation Therapy And Psma

Scientists are also developing targeted therapies based on PSMA, the same protein that is being tested for imaging prostate cancer. For treatment, the molecule that targets PSMA is chemically linked to a radioactive compound. This new compound can potentially find, bind to, and kill prostate cancer cells throughout the body.

In a recent clinical trial, men with a type of advanced prostate cancer who received a PSMA-targeting drug lived longer than those who received standard therapies. Ongoing and planned clinical trials are testing PSMA-targeting drugs in patients with earlier stages of prostate cancer, and in combination with other treatments, including targeted therapies like PARP inhibitors and immunotherapy.

Prostate Cancer: Focus On Therapeutic Vaccines

Prostate Cancer

Diagnosis: A prostate biopsy is necessary to confirm a diagnosis of prostate cancer and to grade the tumor specimen. Ten to 12 samples are usually taken during a prostate needle biopsy using a transrectal approach with ultrasound guidance.4,11Prostate cancers are most commonly graded according to the Gleason system. This system assigns a Gleason grade, using numbers from 1 to 5, based on how much the cells in the cancerous tissue resemble normal prostate tissues. Grade 1 tumors resemble normal prostate cells, whereas grade 5 tumors have cells that seem to be poorly organized. Grade 2, 3, and 4 tumors have features between these extremes. Because prostate cancers often have areas with different grades, the two most predominant grades are added together to yield a Gleason score between 2 and 10. The higher the Gleason score, the more likely the cancer will grow and spread quickly.4The tumor-node-metastasis classification system ,13 the preferred staging system developed by the American Joint Committee on Cancer, is updated every five years to include new pathologic findings. Staging in the TNM system is based on tumor size , nodal status , and presence or absence of metastasis . Similar TNM staging systems have been developed for most other cancers.12 The prognosis for patients with prostate cancer depends on many factors, including the TNM grade, Gleason score, tumor volume, PSA, and patient age.11
