CLL Advocates NZ Newsletter Issue 1
CLL Advocates NZ Newsletter Issue 1
Welcome to our first CLL Advocates newsletter. Like many organisations, we weren’t able to accomplish very much over the lockdown period. We did, however, manage a Trustees’ teleconference to shape up our strategy for the next 12 months. One of the proposals made at that meeting was a monthly newsletter, so here is the first edition.
A huge number of lay and medical articles have been written about the COVID pandemic, and, as you may have seen on our website, we’ve published a number relevant to people living with CLL. See them here. One of particular interest was a consensus statement by Australasian haematologists on management of blood cancers in the COVID pandemic (published in May’s Internal Medicine Journal). It noted that, with a mean age of diagnosis of about 70 years, CLL patients are already likely to be in a high-risk group simply because of age. Advice specifically directed to CLL patients was:
- to delay planned therapy where possible
- to consider using oral agents over IV medications so as to avoid exposure to higher risk environments such as hospital chemotherapy units, for treatment of both initial therapy, and for relapsed/refractory disease (see our recent letter to Pharmac on this matter).
New Zealand has done extraordinarily well at this stage to contain the virus, though it should be noted that vaccination, if successfully developed, may present further challenges for CLL patients.
The CLLANZ Trustees’ meeting agreed that information/education initiatives on CLL should be high on our priority list. In this regard, a review of the current management of CLL by Dr Gillian Corbett, haematologist and trustee, has been published on our website. A detailed CLL patient information booklet is also now close to sign-off and will be published shortly.
In October this year we will be staging a half day or evening combined meeting/seminar on CLL in NZ with the Leukaemia & Blood Cancer (LBC) group, with leading NZ CLL specialists. This will be ‘in person’ in Auckland and also online on Zoom so that people from around the country can join in the discussion and if desired put questions to the speakers. Details will follow soon.
To ensure we reach as many people as possible who have an interest in CLL, we encourage you to become a ‘friend’ of CLL Advocates NZ – by signing up to our newsletter here and/or joining our private Facebook group. You can apply to join the group here.
More details of anticipated activities will follow in subsequent newsletters.
Meanwhile, now that we have passed the winter solstice, and are becoming adjusted to the new ‘normal’, stay well, physically, mentally and spiritually. And please remember that as well as our advocacy role, we want to be a source of knowledge and support for New Zealanders living with CLL, and their families and supporters. To help us achieve this we would welcome and appreciate your feedback, and your thoughts on how we can best achieve our mission.
With best wishes

Dr. Flinn on the Role of BTK Inhibitors in CLL
Dr. Flinn on the Role of BTK Inhibitors in CLL
This story was originally published on OneLive
Ian W. Flinn, MD, PhD, discusses the role of BTK inhibitors in chronic lymphocytic leukemia.
Ian W. Flinn, MD, PhD, director of the Blood Cancer Research Program, Sarah Cannon Research Institute, discusses the role of BTK inhibitors in chronic lymphocytic leukemia (CLL).
BTK inhibitors such as ibrutinib (Imbruvica), acalabrutinib (Calquence), and zanubrutinib (Brukinsa) have been transformative in the treatment of patients with B-cell malignancies such as CLL, mantle cell lymphoma, marginal zone lymphoma, and Waldenström’s macroglobulinemia, says Flinn.
In CLL specifically, BTK inhibitors have become a prominent frontline standard of care, adds Flinn.
Though, it is important to acknowledge that the toxicities that are associated with ibrutinib, including arthralgias, atrial fibrillation, and, though rare, significant bleeding, often lead to treatment discontinuation in patients with CLL.
'CLL flares’ reported after stopping ibrutinib
'CLL flares’ reported after stopping ibrutinib
Patients with ibrutinib-resistant CLL should remain on the BTK inhibitor until immediately before starting their next therapy, Australian haematologists have advised. In a Commentary article in Leukemia & Lymphoma, Dr Chloe Tang and Associate Professor Constantine Tam wrote that ‘CLL flares’ – accelerated CLL progression after ceasing ibrutinib – can be difficult to distinguish from …
Durable disease control achieved with BTKi salvage therapy in patients with CLL
Durable disease control achieved with BTKi salvage therapy in patients with CLL
Patients with chronic lymphocytic leukaemia (CLL) who progress on venetoclax can achieve durable disease control with Bruton tyrosine kinase inhibitor (BTKi) salvage therapy, new Australian research reveals. The study included 23 patients with refractory/relapsed CLL who received a BTKi (ibrutinib [n=21], zanubrutinib [n=2]) after ceasing the BCL2 inhibitor venetoclax due to progressive disease. After initiating …

A current overview of medications in the treatment of CLL in New Zealand
A current overview of medications in the treatment of CLL in New Zealand
A talk presented to the CLL Advocates NZ Board of Trustees on 7 May 2020 by Dr Gillian Corbett MBChB, FRACPath, MRCP, FRACP, Trustee, CLL Advocates NZ https://clladvocates.nz/about-us/trustees/
Not all CLL patients need treatment. Treatment is offered for progressive disease, increasing lymphadenopathy, anaemia, and/or low platelets, as well as rapidly increasing lymphocyte count.
Patients with mutated heavy genes (about 55%) generally carry a better prognosis than those with unmutated heavy genes. This testing is unfortunately unavailable in NZ.
First line treatment
In New Zealand, FCR (fludarabine, cyclophosphamide, rituximab) is standard treatment for younger patients with CLL, up to around 70-75 years. Fludarabine and cyclophosphamide are generally given orally, once per month for up to 6 courses, and rituximab is given as an intravenous infusion once a month. This treatment is very successful for patients with mutated heavy chain genes, and some may potentially be cured. However those with unmutated heavy chain genes do not respond so well and frequently relapse early. A study has shown that such patients respond well to ibrutinib with a better outcome than FCR. However ibrutinib is not funded to treat CLL in New Zealand.
For older patients (70-85 years) the funded first line treatment is bendamustine and rituximab. Each is given by infusion once per month for up to 6 months. This treatment has been shown to be not so effective for younger patients, for whom FCR is preferred, but is better tolerated by older patients
For older patients or those unfit for bendamustine and rituximab, chlorambucil and obinutuzumab is the funded treatment. Obinutuzumab is a more potent antibody than rituximab and has been shown to be more effective in combination with chlorambucil in these patients.
Venetoclax is funded as first line treatment for patients with del17p chromosomal change. These patients do not generally respond well to the other funded treatments. It targets BCL2 which results in an increased rate of CLL cell death. It is given orally and is generally well tolerated but in some patients with bulky disease it may cause tumour cell lysis which can result in kidney damage. Such patients may require hospitalisation for intravenous fluid and supportive care.
Second line treatment
Patients who relapse within 3 years of previous treatment are eligible for venetoclax and rituximab. The venetoclax is to be used for up to 24 months. It is given orally.
Research
There are studies overseas of combining ibrutinib and venetoclax treatment with a view to achieving negative minimal residual disease and possibly cure of CLL. The results of these studies are awaited.
Ibrutinib is a Bruton’s tyrosine kinase (BTK) inhibitor which interferes with CLL cell growth. It is effective in the majority of de novo and relapsed patients with CLL. It is not known to cure CLL. It is generally well tolerated. Other BTK inhibitors that are more targeted are being trialled eg acalabrutinib and zanubrutinib. Tauranga and Waikato Hospitals are part of an international clinical trial comparing ibrutinib to zanubrutinib in relapsed CLL.
Other areas of research are in the development of immune therapies eg CAR-T cells to target CLL cells.
Coronavirus: Separating Fact From Fiction for CLL Patients
Coronavirus: Separating Fact From Fiction for CLL Patients
“We’re learning every day, and we’re modifying and adjusting based on what we learn,” says Dr. William Wierda, from The University of Houston MD Anderson Cancer Center, as new information continues to come to light on the novel coronavirus.
Can cancer medicines be used to treat COVID-19? Does the effect of the virus vary by CLL subtype? Is ibrutinib (Imbruvica) being mixed with Coca-Cola? Watch to hear expert perspectives on questions like these and more.
With much misinformation circulating online, Dr. Wierda and Dr. Kerry Rogers, from The James Comprehensive Cancer Center at OSU, joined Patient Power to help chronic lymphocytic leukemia patients separate fact from fiction and explain how care is being modified during the pandemic.

COVID-19's Impact on How Patients with CLL, Myeloma Have Received Treatment
COVID-19's Impact on How Patients with CLL, Myeloma Have Received Treatment
CURE® recently invited patients, survivors, caregivers, advocates and health care professionals to attend its first-ever live webinar, “Hear from the Experts: COVID-19 & Cancer Care for Patients.”
Sponsored by Janssen and Pharmacyclics, the webinar was designed to provide those affected by chronic lymphocytic leukemia (CLL) and myeloma with information and updates as it pertained to the current landscape of cancer care during the uncertain times of the new coronavirus (COVID-19).
Dr. Saad Usmani, chief of the Plasma Disorders Program and director of clinical research in hematologic malignancies at the Levine Cancer Institute served as the moderator for the webinar. Panelists included:
- Dr. Zainab Shahid, medical director of bone marrow transplant infectious diseases at the Levine Cancer Institute
- Dr. Farukh Awan, director of the Lymphoid Malignancies Program at the Harold C. Simmons Comprehensive Cancer Center at UT-Southwest
- Dr. Ian Flinn, director of the Lymphoma Research Program at Sarah Cannon Research Institute
- Dr. Lee Greenberger, chief scientific officer at the Leukemia and Lymphoma Society
In the first part of this series, Dr. Farukh Awan addresses how the pandemic has affected his practice, as well as how it has impacted how patients with CLL and myeloma have received care.
Awan: We’re all learning. This is something that none of us have experienced before, so we’re learning more and more about the virus with every passing day. There’s more data coming out. There’s a lot of new clinical trials happening, so everything is happening at the same time we are all trying to do the best we can to decrease the spread of this so we can better manage our patients who do get infected and that would not overwhelm the system.
In line with that, every institution has instituted a policy that suits their needs. Fortunately, in Dallas we started with social distancing early and I think we were able to keep the numbers fairly manageable. And yet, we still had to make a lot of changes to the way we practice.
In terms of outpatient management, we have limited the number of visitors that come in with the patient. We try to keep them outside of the clinic area. We also have tried to make the most of our electronic visits so that the least number of patients get exposed to the staff, and vice versa. We have also started utilizing local labs, which are a lot of times not as busy as the oncology clinics and cancer centers. Those labs then give us the results from the blood work that we need. I think we’ve utilized all of these approaches on the outpatient side. We’ve also been fortunate that we have a service for drive-through testing for patients who have active symptoms. We are trying to get them through the drive-through testing and if they are positive, then they’re asked to quarantine at home.
For those who do get really sick and need to go to the hospital, the ER has a system where everybody gets quarantined on arrival. They get tested in a timely manner with a rapid test for their COVID-19 and if they are positive, they are then sent to a specific isolation floor meant for those patients. There are mechanisms in place, both on the outpatient and inpatient side, which have tried to minimize exposure to patients, family members, and staff at the same time.
As far as for patients with chronic lymphocytic leukemia (CLL) who are concerned, a lot of our patients can afford to wait a little bit to start their new treatment. For patients who are not actively getting treated, we do plan on delaying their treatment until at least we have some idea of better treatment modalities and if their symptoms can be managed by other approaches. For those who are on active treatment, we are trying to continue those treatments while trying to minimize their return visits and we’re trying to do that electronically as much as possible, either via telephone calls or through a video visit. Either option is being utilized so that patients can limit their back and forth to the clinic.
We know that our patients with CLL are especially at a high risk of getting infections. Infection-related complications are one of the leading problems in our patients. We expect that our patients would be at an extremely higher risk and that’s why we are also advising that they socially distance themselves from any known patient or persons who might have the virus. We are now also learning that there is a fairly large group of patients, or people in the community, who would have asymptomatic disease and they can potentially spread the disease to a lot of other people without even knowing that they have the virus, and I think that’s very scary for our patients since they are immunocompromised at baseline, even without treatment.
It’s a unique challenge. We are recommending that all our patients with CLL practice social distancing, minimize exposure, and even if they don’t have to go out for groceries they shouldn’t. I think if we can do that over the next few months, hopefully, we can right this and hopefully we will get our patients through it without having any serious complications.
On the other hand, some patients with lymphoma can wait to start treatment, some of them cannot. In some aggressive lymphomas, the treatments need to be started right away. For those patients who need to start treatment right away we are following them very closely for any symptoms. If they exhibit any symptoms, like fevers or a cough or any upper or lower respiratory tract symptoms, we are testing them before we give them any chemotherapy. If somebody is positive for the virus, we are not using chemotherapy for those patients and we are trying to delay chemotherapy as much as possible.
For patients already on treatment and need to be admitted to the hospital we are screening them with a test 48 to 72 hours prior to their admission to the hospital, and once they’re negative, they can then start their treatments. We’re trying to use all these resources that are available to us to try to minimize the risk, again, to the staff and to patients and to prevent any complications that might happen in the future.
Finally, I’d like to make a point regarding stem cell transplants and CAR T. These can be potentially curative options for our patients. We also realize that a lot of our patients will get extremely sick during that process. So, we have multiple challenges with regards specifically to stem cell transplants and CAR T. We’ve also learned that the Red Cross and blood banks are being stretched and that their resources are limited. The number of donors is limited. Since there aren’t a lot of donors like we normally would have, getting access to blood products can be a challenge for our transplant patients, especially if they need blood transfusions and platelets.
We’re trying to very specifically look at all the factors for every patient who is undergoing an autologous transplant, or a CAR T cell treatment and we are trying to select the patient who absolutely needs to proceed with it. We are taking that patient to transplant and are employing a multitude of tests at various time points and making sure there are no visitors during their hospital stay, and as much as possible we are ideally using electronic visits for follow-up to minimize exposure.
Have we done transplants in the last few months? Absolutely. We’ve also done CAR Ts and we have successfully and safely gotten patients through it, but it’s challenging. It can be done but we have to be extremely careful that we minimize exposure to our patients and hopefully we can all get through this.

How COVID-19 Has Impacted Clinical Trials for Chronic Lymphocytic Leukemia
How COVID-19 Has Impacted Clinical Trials for Chronic Lymphocytic Leukemia
Many patients with chronic lymphocytic leukemia (CLL) rely on the outcomes of clinical trials that examine new ways to treat the disease. But with the new coronavirus (COVID-19) pandemic changing the way health care is provided around the country, so too is participation in these trials, according to Dr. Brian Koffman, the co-founder, executive vice president and chief medical officer of the CLL Society.
CURE® recently spoke with Koffman about how clinical trial participation has become more flexible over the course of the pandemic in an effort to keep immunocompromised individuals like those with CLL safe, by utilizing things like telemedicine and localized care to avoid exposure to the virus.

New Research Shows Real-World Track Record of Common CLL Therapies
New Research Shows Real-World Track Record of Common CLL Therapies
New Research Shows Real-World Track Record of Common CLL Therapies
A new study offers real-world insights into the results of several common and emerging therapies for chronic lymphocytic leukemia (CLL), and suggests differences in how the drugs perform in community settings versus clinical trial settings.
The study, based on the Connect CLL registry, was published this month in Blood Advances. The registry enrolled 1494 patients with CLL who sought treatment at 199 healthcare centers in the US between the years 2010 and 2014. Most of the centers were community-based. Patients were grouped by line of therapy upon enrollment in the study, and the median follow-up was 46.6 months.
The most common treatments in the study were bendamustine and rituximab (BR), with just over one-third of patients receiving that therapy. Next was fludarabine, cyclophosphamide, and rituximab (FCR), which was given to 21.4% of patients. Rituximab monotherapy was prescribed in 18.5% of cases.
Median overall survival (OS) was not achieved in the first line of therapy; median OS was 63 months in the second line of therapy, and 38 months in the third or higher line of therapy.
In the first line of therapy, median event-free survival (EFS) was 59 months for patients on BR and 55 months in FCR. In a multivariate analysis, BR or FCR in the first line of therapy outperformed the other therapies in both OS and EFS. Anthony Mato, MD, of Memorial Sloan Kettering Cancer Center, and colleagues noted that ibrutinib also had a positive impact, according to the data.
“As expected, EFS and OS became shorter and response rates decreased as LOT increased,” Mato and colleagues wrote. “In addition, ibrutinib therapy improved OS in all R/R [relapsed or refractory] patients regardless of the LOT in which it was received (LOT2, LOT3, or LOT≥4), even though it was approved by the FDA after the start of the Registry.”
The timing of the study period also meant that no patients in the study received ibrutinib in a frontline setting.
Pneumonia (11.6%) and febrile neutropenia (6.2%) were the most common adverse events.
The investigators used the data to identify a new category of patients at particularly high risk of death within 2 years of enrollment. The group was defined by a number of characteristics, including site of enrollment, race, age, insurance coverage, income, enrollment regimen, Charlson Comorbidity Index score, Eastern Cooperative Oncology Group Performance Status score at enrollment.
The analysis differed from some clinical trials in that it did not show a significant advantage for FCR over BR. The findings suggest that FCR’s advantages may not translate into community practice, Mato and colleagues said, adding that it might be due to less-rigorous use of the therapy in a real-world setting.
Though the treatment landscape evolved over the course of the study (and continues to evolve), the authors say the study has meaningful insights for clinicians as they make treatment recommendations.
“Receiving novel agents in LOT2 improved outcomes in patients who received previous CIT [chemoimmunotherapy], supporting the inclusion of ibrutinib, idelalisib, duvelisib, and venetoclax in the treatment paradigm for patients with R/R CLL,” they wrote. “However, additional randomized clinical trials and real-world data are needed to establish the role of non-CIT regimens in the treatment of patients with R/R CLL.”

CLLANZ calls for home-based treatment for CLL patients during COVID pandemic
CLLANZ calls for home-based treatment for CLL patients during COVID pandemic
Last week CLL Advocates New Zealand wrote to Pharmac requesting them to provide temporary access to ibrutininb (taken in tablet form at home) for del17p and RR patients, and for newly diagnosed fit and unfit patients.

Dear Peter Murray, Deputy Medical Director
Thanks for your email clarifying the nature of changes Pharmac has made under Special Authority with respect to the management of cancer medicines, in light of the current COVID-19 crisis.
You have asked if I have any ideas on this issue that I would like to put forward for consideration and indeed I do. They concern risks posed by aspects of the current treatment of patients with CLL, as follows.
- A fellow Trustee of CLL Advocates NZ (CLLANZ), haematologist Gillian Corbett, has raised serious concern about the risks posed to patients in the administration of the current funded standard-of-care treatment for patients with del17p and relapsed refractory CLL. She has a patient starting treatment this week who had to go across town for urgent lab testing twice in one day, and again the following morning for tumour lysis syndrome (TLS) management. She noted that IV hydration needs to be considered in these patients, and that her patient will likely need to have more urgent blood tests during the coming week. She will need to have the procedure repeated next week. Gillian is very concerned about patients like this one having to put themselves at risk by going to the labs where there is likely to be a long wait, which in their immune-suppressed state would increase their risk of infection, including COVID-19.
For this reason we would like to propose that a change to CLL treatment be made under Special Authority to enable ibrutinib, which is taken in tablet form at home, to be funded temporarily for del17p and relapsed refractory CLL patients. In addition to being a home-based treatment, ibrutininb requires very little monitoring, infrequent blood tests and infrequent attendance at hospital (outpatients).
- We also propose that the Special Authority enables newly diagnosed fit and unfit patients to access ibrutinib, to avoid the need for chemotherapy or a delay in initial treatment. Again this would be a temporary SA to be in place until such time as patients can safely undergo in-hospital care.
- Finally we propose that the Special Authority for ibrutininb should also apply to treatment for CLL patients who are having intravenous therapy in a hospital setting, such as rituximab or obinutuzumab, which is given by infusion and requires, particularly initially, prolonged attendance at the chemotherapy department which is highly undesirable at this time of the COVID-19 epidemic.
As you would know, patients with CLL are immuno-compromised, and most are in the most at-risk age group, so we believe for all these reasons Pharmac should move quickly to make these changes.
I don’t have an accurate understanding of the numbers of patients this would involve, and I’m currently canvasing CLLANZ subscribers for further input on this issue. But I understand there has been a significant drop in people presenting with CLL, no doubt due to the general pattern of people avoiding going to the doctor. The same may be true of RR patients. I understand that HSANZ may be looking at the likely number of patients who would benefit from these changes, but that the numbers involved are likely to be very small and the costs therefore low.
It seems to me, at a time when so much effort is going in to saving lives, implementing this proposal would be a most worthwhile contribution from Pharmac.
I’d be very happy to discuss this with you or provide any further information you may require, and look forward to hearing back from you on this request.
Kind regards
