  1. Chalkie asks: I am now having to choose between Zytiga and Xtandi. Is there a forum for this? Any suggestions? Jim Marshall (not a doctor) said ... A recent trial for men with metastatic prostate cancer who were no longer responding to ADT alone (mCRPC) showed similar outcomes on both drugs. So, it appears your doctor could recommend either, unless they are worried about how a particular side effect may affect you personally: If you have a health condition that could be made worse by possible seizure or fatigue, your doctor may steer away from Xtandi. If you have a health condition that could be made worse by possible by increased blood pressure, low potassium, or increased liver enzymes, your doctor may steer away from Zytiga. ... end Jim A link to an article on this can be found here: Abiraterone and Enzalutamide equivalent as first-line therapy in metastatic hormone therapy- resistant prostate cancer
  2. Last Friday 10 March 2017 the Pharmaceutical Benefits Advisory Committee (PBAC) reached its initial decisions on drugs to go onto the PBS at reduced prices. This included whether to put Xtandi (Enzalutamide) before chemo on the PBS. The company will be told of the result next Friday 17 March 2017. If necessary, negotiations between the PBAC and the company continue for 4 weeks. The final results will be published on the PBAC website 21 April 2017. (If the company is not happy with the result, they have until July 2017 to appeal.)

  5. The opportunity There is a chance to have your voice heard on whether the drug Xtandi (enzalutamide) should be available on the PBS BEFORE chemotherapy. Timing Submissions are due Wednesday 8 February 2017, and no late submissions will be accepted. Enzalutamide on the PBS An important drug for men with advanced prostate cancer is Xtandi, also called enzalutamide. The first evidence that enzalutamide worked looked at using enzalutamide AFTER the chemotherapy drug docetaxel. A committee of experts looked at this evidence. They recommended that it was worth spending taxpayer money on. So, now men with advanced prostate cancer can get enzalutamide on the PBS at a low price, AFTER they have had chemotherapy with docetaxel. Some new evidence has arrived showing that enzalutamide works well BEFORE chemotherapy with docetaxel. The same committee of experts is now looking at this evidence to see if it is worth spending taxpayer money to put enzalutamide on the PBS for use BEFORE chemotherapy with docetaxel. This is the second time this has come up for consideration. The first time, the expert committee rejected the application: because the submission was focused on a claim of survival advantage, which was small and uncertain, rather than on outcomes that clinicians and patients considered to be of most value. The purpose of using enzalutamide earlier in the disease pathway would be: 1) to delay symptoms from developing and maintaining a better quality of life for longer in asymptomatic patients for whom placebo, or watchful waiting, is the appropriate comparator; and 2) delaying the toxicities of chemotherapy in symptomatic patients considered suitable for docetaxel. That committee has asked for public submissions for a new application. Enzalutamide BEFORE chemotherapy The first thing you should understand that enzalutamide is not a miracle cure. About half the men on the PREVAIL clinical trial were still alive three years after they started on enzalutamide. Some of the men who responded will have a much longer survival. I have met a man whose cancer has been kept at bay for 6 years so far on enzalutamide. But survival times pre-chemo and post-chemo are not different enough to convince the experts. What is most important about this drug is the quality of life it makes possible during that two or three years. Docetaxel chemotherapy vs enzalutamide side effects The first thing you should understand is the current first treatment at this stage - docetaxel chemotherapy. Many men report coping quite well with their docetaxel, finding the temporary hair loss and other side effects manageable. But some men have a terrible experience with the side effects. It is so bad for some men that they give up the treatment. And, about one man in four hundred dies from the treatment. On the other hand, enzalutamide treatment has far fewer reported side effects. Fatigue and hypertension were the most common. So, the first benefit of starting enzalutamide BEFORE chemotherapy is that a man can delay the start of the docetaxel chemotherapy. The PREVAIL clinical trial In the PREVAIL clinical trial of enzalutamide before chemotherapy, men had to: have metastatic prostate cancer, be castrate resistant, and have no, or few symptoms (like pain). Metastatic means that their prostate cancer had spread to other parts of their body. Castrate resistant means that the primary hormone therapy, with drugs like Zoladex, Lupron, and Eligard, was no longer able to keep the cancer in check by itself. In other words their PSA was rising, despite the hormone therapy keeping testosterone very low. Men in this trial on enzalutamide did not need to start chemotherapy, on average, for more than two years - 28 months. The control group of men had to start chemotherapy after 11 months. So men on enzalutamide had 17 MORE months at a higher quality of life. After 12 months of treatment, 65% of men treated with enzalutamide had scans which showed no progression of their cancer, compared to 14% of the control group. The trial was finished early when it became clear that the enzalutamide was far more effective. At that stage, 29% fewer men had died in the enzalutamide group. The enzalutamide group also had a longer time until the first skeletal-related event (that is, problems with their bones). Most prostate cancer metastases (about 89%) occur in bones. Of the men with metastases away from their bones, complete or partial soft-tissue response favoured enzalutamide 59% to 5%. Time until PSA started going up again also favoured enzalutamide. So did the number of men whose PSA dropped to at least half - 78% to 3%. Submissions The Prostate Cancer Foundation of Australia (PCFA) is making a submission on behalf of its members. Some individual members have told me that they are going to put in an individual submission.

  6. Click here to read Malecare's report of a clinical trial which found that combining Xtandi and Zytiga and using them at the same time was NOT better then either of the drugs by themselves.
  7. Joel Nowak of Malecare reports on an abstract presented at the 2016 American Society of Clinical Oncology (ASCO) Scientific Meeting about how abiraterone (brand name Zytiga) and enzalutamide (brand name Xtandi) may cause cognitive impairment and mood changes. Interestingly the research showed that these side effects were more prevalent with enzalutamide than with abiraterone. Click on this link to read the Malecare report..
  8. You will have noticed that the other members of our Executive Committee (Alan Barlee, Nev Black, Paul Hobson, Tony Maxwell) make an enormous contribution to our monthly phone-in meetings, to information and discussion posted on our website (JimJimJimJim.com), and to general support of our members by phone, email, and at Face-to-a-name members' meetings. What you may not be aware of is that your Executive Committee also spends much time and effort in advocacy duties on behalf of the group. Below are some advocacy events held during the past year. Please be aware that where I am listed as the sole attendee below, most often, most of the background work has been done by other members of the Executive Committee. Health Week Launch This event, co-sponsored by the Prostate Cancer Foundation of Australia (PCFA) and Astellas (vendors of Xtandi (enzalutamide)) was a press briefing in Sydney to help the press focus on actual men with advanced prostate cancer in their Health Week reporting. After a formal presentation, Paul, Alan, Tony and I joined PCFA CEO Anthony Lowe in one-on-on discussions with members of the press about advanced prostate cancer and with Astellas staff about getting Xtandi (enzalutamide) on the PBS pre-chemotherapy. Later in the day I caught up with Sydney members of our group, and in the evening attended the Westmead Prostate Cancer Support Group. Before flying back next morning I met with Professor Peter Croucher at the Garvan Institute of Medical Research to discuss the research Professor Croucher's team is doing on finding and treating cancer that moves to bones. Multi-parametric MRI scan and biopsy The Medical Services Advisory Committee (MSAC) is an independent expert committee that recommends to the Minister which procedures should go on the Medicare Benefits Schedule (MBS). A multi-parametric MRI is a scan which can show more detail of prostate cancer, especially in the prostate. Australia's Radiation Oncologists made an application to have the multi-parametric MRI made a Medicare item. Your Executive Committee made a submission on your behalf to the MSAC supporting this application. Pharmaceutical Benefits Advisory Committee (PBAC) review The PBAC is the independent expert committee that recommends to the Minister which drugs should go on the PBS. You may remember that, as the result of submissions by our group and of many personal submissions on the drugs Zytiga (abiraterone) and Xtandi (enzalutamide) that I was invited to appear before the Senate Inquiry into the availability of new, innovative and specialist cancer drugs in Australia. Just one week after the Inquiry ended, Minister for Health Sussan Ley announced a review of the PBAC to "address technical methods issues raised by the PBAC and stakeholders". A team at the University of Adelaide prepared a new set of guidelines for the operations of the PBAC, and Tony Maxwell and I attended the PBAC Guidelines Review - Presentation Forum in Sydney. Amongst a large group of pharmaceutical and medical experts, Tony's contribution beginning "I am a patient ... " had a striking effect. With not enough room for my scooter in the morning tea room I had to stay in the main auditorium. The only other person there was PBAC Chair, Professor Andrew Wilson, setting up his slides. When he finished setting up, he came over and we had quite a long and productive talk. Office of the Minister for Health All members of your Executive Committee met with Mark Kinsela, Senior Advisor to the Minister for Health at the office of the Minister in Canberra to discuss issues of import to men with advanced prostate cancer. In the generous 1 hour 20 minutes we were given we were able to cover many issues, and felt we were given a well-informed and probing hearing. Access on the PBS to the drugs Zytiga (abiraterone) and Xtandi (enzalutamide) before chemotherapy, and access on medicare to the radiotherapy drug Xofigo (Radium-223) were, of course an important focus of the discussion. PCFA support groups meeting I met with PCFA senior staffers Amanda Pomery (National Manager, Support & Community) and Katie Dundas (Manager, Community Awareness and Education) a few weeks ago to talk about our issues as a support group. The changes that are happening to our website at the moment, and the new flexibility we have with our phone-in meetings are a couple of the results. (Our next phone-in meeting will be an early evening one - a roundtable at 5:30 pm on Friday 24 June 2016.) Getting Bayer Xofigo on Medicare Earlier this month when plans for a meeting at Bayer in Sydney fell through, senior staff of Bayer Pharmaceutical and PCFA CEO Anthony Lowe flew to Brisbane to speak to me about the problems of getting Xofigo (Radium-223) on Medicare, as a result of a letter your Executive Committee had sent to Bayer. It turned out that Bayer now feels able to re-reconsider an earlier approach they had abandoned, and that as a result of our discussion on Medical Services Advisory Committee (MSAC) guidelines they will more clearly identify the logjams and get back to us. Election 2016 Your Executive Committee had made suggestions to PCFA about presenting a comprehensive policy document to parties for their support. Meeting with PCFA CEO Anthony Lowe, I came to support his opinion that a single policy item presented to all party leaders in person by Anthony would be in the best interests of men with prostate cancer. Executive Committee members concurred later in the day. One week later, while visiting Launceston General Hospital in Tasmania, Shadow Minister King announced that the Labor Party has committed to securing the existing Department of Health funded prostate cancer nursing positions for a further 3 years from 30 June 2017 and will fund an additional 14 prostate cancer nurses across Australia. Anthony was scheduled to meet with other party leaders. Getting Zytiga (abiraterone) on PBS pre-chemotherapy Your Executive Committee sought to meet with Janssen (a Johnson & Johnson subsidiary) to discuss progress on getting Zytiga (abiraterone) on the PBS pre-chemotherapy. As a result, Janssen brought together a Prostate Cancer Patient Working Group meeting in partnership with PCFA last Friday 27th May 2016 in a meeting room at Sydney Domestic Airport. Anthony Lowe and Katie Dundas of PCFA, Paul Hobson, Alan Barlee, Nev Black, Graham Bloomfield, Kerry Drinkwater, David Abrahams, Zeni Muhiji and I attended. Several of those attending had abiraterone experience. We heard a presentation from Prof Gavin Marx on current therapeutics in advanced prostate cancer, and had some hours talking with Janssen staff about issues. Disclosure Your Executive Committee and other members taking part in the above advocacy activities above have signed various commercial-in-confidence agreements and will not be free to discuss details in those cases. Only one of the activities listed above included a financial recompense for time contributed. PCFA contributed travel costs in several cases, but travel and accommodation for the Canberra meeting were met by committee members themselves. Personal note An amazing thing about the Executive Committee members who assist me in running the Australian Advanced Prostate Cancer Support Group is that, as well as the enormous work they do for us, each takes a central role in their local Prostate Cancer Support Group, and on various research project teams, and general prostate cancer activities, stepping forward whenever a person is needed. We have made great strides with our advocacy in the past three years. Members' submissions to the PBAC have paid an important part. But on top of that, the vital part paid by the other members of the Executive Committee, especially in the past year, had laid an important foundation for the next year. We can look forward to the reform of the PBAC/PBS process and hopefully getting pre-chemo approval for Zytiga, Xtandi and Xofigo at least. I am proud to work with these men and with this group.

  9. The New Prostate Cancer Infolink has an article about the announcement of a new clinical trial of Enzalutamide (brand name Xtandi) in men with metastatic, hormone-sensitive prostate cancer. This trial will be recruiting men In Australia. The New Prostate Cancer Infolink expresses concern about the suitability of this trial for men newly diagnosed with a significant presence of metastatic disease.

  10. Respected prostate cancer advocate, Joel Novak from Malecare, believes that Xtandi is superior to Zytiga. Click on this link to read his reasons why he thinks this. Do you agree?
  11. New Agents available overseas pre chemo

    In the United States men with prostate cancer can get access to Abiraterone (brand name Zytiga) and Enzalutamide (brand name Xtandi) before chemotherapy. We'd like to get to a stage in Australia where Abiraterone (brand name Zytiga) and Enzalutamide (brand name Xtandi) are available on the Pharmaceutical Benefits Scheme before chemotherapy. The Australian Pharmaceutical Benefits Advisory Committee, when considering applications to put drugs on the Pharmaceutical Benefits Scheme, looks at what its overseas equivalent bodies have done. Thanks to member Russ for letting us know that since 11 December 2015 Enzalutamide (but not Abiraterone) is now routinely available on the National Health Scheme in England and Wales, regardless of whether or not a man has previously been treated with docetaxel chemotherapy. In Scotland it's the reverse - Abiraterone (but not Enzalutamide) is now routinely available on the National Health Scheme in Scotland, regardless of whether or not a man has previously been treated with docetaxel chemotherapy. http://prostatecanceruk.org/about-us/news-and-views/2015/12/nice-decision-on-abiraterone-and-enzalutamide-without-chemotherapy
  12. At its November meeting the Pharmaceutical Advisory Committee (PBAC) considered an application to extend the listing of enzalutamide (brand name Xtandi) to include treatment of metastatic castration-resistant prostate cancer (mCRPC) in patients who have not had prior docetaxel (chemotherapy). The PBAC has released its decision on the application. It is what the PBAC describes as a "1st time decision not to recommend". It's disappointing that the application was not successful but encouraging that the PBAC is asking Astellas to resubmit the application. Here is the full decision from the PBAC: "The PBAC decided not to recommend extending the PBS listing of enzalutamide to include treatment of metastatic castration-resistant prostate cancer (mCRPC) in patients who have not had prior docetaxel because the submission was focused on a claim of survival advantage, which was small and uncertain, rather than on outcomes that clinicians and patients considered to be of most value. The purpose of using enzalutamide earlier in the disease pathway would be: 1) to delay symptoms from developing and maintaining a better quality of life for longer in asymptomatic patients for whom placebo, or watchful waiting, is the appropriate comparator; and 2) delaying the toxicities of chemotherapy in symptomatic patients considered suitable for docetaxel. The PBAC noted the median time to initiation of cytotoxic chemotherapy in the PREVAIL trial was 28.0 months in the enzalutamide group versus 10.8 months in the placebo group, a median difference of 17.2 months, which was clinically meaningful. In contrast the overall survival gain of 4 months for enzalutamide in the same trial compared to enzalutamide in the post-docetaxel setting (4.8 months from the AFFIRM trial) highlighted the minimal impact of earlier enzalutamide treatment on overall survival. The PBAC therefore rejected the application because it did not appropriately reflect the value of early enzalutamide treatment. The PBAC encouraged a resubmission to evaluate the potential gains in quality of life based on the patient populations and outcomes described above". The Drug Company commented: "Astellas is disappointed not to have secured an extended PBS listing for patients with mCRPC who have not had prior docetaxel, but is grateful to the PBAC for their helpful feedback and advice."
  13. http://tinyurl.com/pcwv6zd Information in the above reference indicates that the administration of Xofigo/Alpharadin/Radium 223 in company with abiraterone/Zytiga increased the effectiveness of Xofigo as well as overall survival. Combining EBRT (External Beam Radiation Therapy) with Xofigo increased likelihood of bone marrow failure.
  14. New Clinical Trial of JNJ-56021927

    JNJ-56021927 (formerly known as ARN-509) is an androgen receptor antagonist. Some prostate cancer cells require androgens for growth. JNJ-56021927 prevent androgens from binding to the prostate cancer cells’ androgen receptors. JNJ-56021927 is not as advanced in its development as enzalutamide (Brand name Xtandi). Results from initial clinical trials suggest that JNJ-56021927 may be more potent and effective than enzalutamide. A Phase 3 Randomized, Placebo-controlled Double-blind Study of JNJ-56021927 in Combination With Abiraterone Acetate and Prednisone Versus Abiraterone Acetate and Prednisone in Subjects With Chemotherapy-naive Metastatic Castration-resistant Prostate Cancer is being conducted. Details of this trial can be found by clicking on this link: https://clinicaltrials.gov/ct2/show/NCT02257736 This clinical trial is being conducted at a number of hospitals in most Australian states. I am aware that the Royal Melbourne Hospital has commenced recruitment of patients for this trial. I'm not aware of the recruitment status of the other Australian sites but I expect that these sites will commence recruitment shortly, if they are not already doing so. There will be 2 arms of the trial. Patients on the 1st arm will receive Abiraterone, Prednisone and JNJ-56021927. Patients on the 2nd arm will receive Abiraterone, Prednisone and a placebo.
  15. PLATO is a 2 stage Clinical Trial with 500 patients (80% in Australia, rest in Finland, UK and USA). On Stage1 everyone gets Enzalutamide (no placebo). [Xtandi is the brand name for Enzalutamide] Those continuing in Stage 2 are randomised: 50% of patients to Abiraterone plus placebo and 50% of patients to Abiraterone plus Enzalutamide. Both arms in Stage 2 also get Prednisone to go with the Abiraterone. Stage 2 is double blind so neither doctor or patient know which arm you are in. Also in Stage 2 they do not do PSA tests but track the tumour with scans. That sounds a little scary! If I get twitchy, I may have to cheat – or just turn off the brain, lie back and think of England. To qualify for Stage 2 you need to continue to meet the original general requirements for the trial. The original changeover point from Stage 1 to Stage 2 was defined as a 25% increase in PSA over a 1 or 2 month period following the nadir (lowest point). This has now been relaxed by adding a second additional requirement – growth in tumours or metastases as shown by CT or bone scan. All men on the trial had to have CT or bone scan visible tumours or metastases at the start of Stage 1. My tumour was only discovered at PSA 70 just before start of Stage 1. Given they now know where it is, they may be able to track its growth at lower PSA’s but the effect of adding this second requirement would likely give me more time on Stage 1 than originally which should be a positive – my tumour is probably currently invisible at PSA 13. I have a Clinical Trial consultation every 4 weeks and, of course, I chat with the other guys in the waiting room – and they with me. I started the trial in June 2014 – most guys started between Jan 2014 and June 2014. Their PSA’s at start of the trial vary a lot – 30 to 500 on the guys I have talked to. All seem to be getting a reasonable response but the details vary a lot – how fast it drops, how low it goes, how long it stays there etc etc. I have not spoken to anyone yet who is on stage 2. With the trial we are doing two sequences of PSA tests to monitor results: 1.Local pathology lab (Douglass) Results 65 (June 14), 38, 25, 15, 20 (end Nov) and 13 (23 Dec) 2.Official trial pathology lab in Singapore Singapore result end Nov was 14. It looks like my PSA results are bottoming out in the 10-15 range and the local end Nov result is incorrect. What side effects have I had from my treatment so far on the trial? My main side effect from Lucrin over the last 11-12 years has been fatigue – in my case always there but manageable. The only side effect I get from Enzalutamide is substantially increased fatigue – to the point of needing a doze most afternoons. Talking to doctors and patients, substantially increased fatigue is the main Enzalutamide side effect for most men.
  16. AR-V7 is an androgen receptor variant which, if found in the blood stream, disables the effectiveness of either Xtandi/enzalutamide or Zytiga/abiraterone acetate. I have prepared a summary of recent research about AR-V7 which is available at http://tinyurl.com/qbgpezo [Ed - Chuck's paper mentions blood tests for Circulating Tumour Cells (CTC) and AR-V7. These tests are not routinely available in Australia.]
  17. Thanks to Chuck Maack for drawing our attention to the report of a recent presentation by Dr Oliver A Sartor who was the principal North American investigator for the clinical trial that led to the approval by the United States Food and Drug Administration (FDA) for radium 223 (brand name Xofigo). In 2013 the FDA approved radium 223 for treatment for patients with castration-resistant prostate cancer, symptomatic bone metastases, and no known visceral metastatic disease. Dr Sartor said that determining whether or not a patient had symptoms of bone metastases could often be a grey area. He considered the extent of bone metastases was more important than the presence of pain in determining whether to treat a patient with radium 223. Dr Sartor was treating patients with metastatic castration-resistant prostate cancer who had a significant burden of bone-metastatic disease, even though they might not be considered symptomatic. After nearly a year of clinical use, Dr Sartor said that the optimal setting for radium 223 appeared to be in combination with new hormonal therapies such as Abiraterone (Xytiga) and Enzalutamide (Xtandi). At present a large multi-country Stage III clinical trial is about to start recruiting in Australia: Radium-223 Dichloride and Abiraterone Acetate Compared to Placebo and Abiraterone Acetate for Men With Cancer of the Prostate When Medical or Surgical Castration Does Not Work and When the Cancer Has Spread to the Bone, Has Not Been Treated With Chemotherapy and is Causing no or Only Mild Symptoms Dr Sartor said large clinical trials would be needed before radium 223 could be considered for use on patients who did not have metastatic disease or were not castration-resistant.
