Experts Discuss Treatment Advances for Chronic Lymphocytic Leukemia

Experts Discuss Treatment Advances for Chronic Lymphocytic Leukemia

This article was originally published by Pharmacy Times

In the Pharmacy Times ® Directions in Oncology™ Insights series on chronic lymphocytic leukemia (CLL), experts Alison Duffy, PharmD, BCOP, and Cody Steeves, PharmD, BCOP, discussed current treatment recommendations and what is next for the disease state.

CLL is a rare cancer of the blood and bone marrow, and although it is difficult to treat many advances have been made in the past 6 years, said Duffy, an associate professor, clinical pharmacy specialty in oncology at the University of Maryland School of Pharmacy.

Earlier recommendations included single-agent chemotherapy or single-agent monoclonal antibodies, but Duffy explained that patients are increasingly receiving small molecule inhibitors, including Bruton tyrosine kinase (BTK) inhibitors.

Without the use of single-agent chemotherapies or single-agent monoclonal antibodies, Duffy said pharmacists can see patients with CLL in many settings.
“Using those as single agents, or more commonly in combination, that’s where the pipeline and future directions are really moving towards, with combination therapy as well as more potent, more selective, targeted therapies,” she said.

According to recommendations from the National Comprehensive Cancer Center (NCCN), Duffy said some current frontline treatment agents include ibrutinib, venetoclax plus obinutuzumab, acalabrutinib with or without obinutuzumab, and chemo-immunotherapy, when warranted.

Frontline therapies present various challenges, although Duffy said the treatment criteria has become less rigid.

“Some of the things that I would think about would be age, fitness, comorbidities such as atrial fibrillation, and renal function if I was going to give something like fludarabine within the FCR [fludarabine, cyclophosphamide, and rituximab] regimen,” Duffy said.

She added that considering patient preferences and clinical experiences is important. Some patients may not be great candidates for oral therapy due to a lack of access, finance, comfort level, or adherence challenges. Similarly, transportation might be an issue for patients receiving intravenous chemotherapy and should be considered.

“Moving forward, it’s positive to see that the outcomes, when they’re stratified by those patients with the deletions, still tend to trend in the positive direction for those patients with these newer oral therapies we’ve had over the past 5 or 6 years,” Steeves said.

The experts also turned their attention to minimum residual disease (MRD) testing and how it affects the use of limited duration therapy. MRD testing is particularly helpful for diseases that require stronger treatments, Steeves said. He explained that some data has found that obtaining a low or negative MRD corresponds with significantly increased progression-free survival compared with medium or high levels of MRD. However, patients receiving oral agents, especially single-agent BTK inhibition alone or with a CD20 inhibitor, are not expected to achieve MRD. Despite the lack of MRD, Steeves said these agents can be valuable.

“Even though we’re not seeing those deep remissions with MRD negativity, undetectable MRD, we certainly are still seeing a large benefit of using these agents without that,” Steeves said.
Steeves, clinical oncology pharmacist, Biologics by McKesson, also emphasized the importance of a patient-specific treatment plan. Some patients may want to take the drug for as short a period as possible, while others find that it does not disrupt their daily lives to a large extent because they are already receiving multiple medications.

Finally, Duffy and Steeves turned their attention to BTK inhibitor monotherapy for patients with newly diagnosed CLL. Ibrutinib, a new BTK inhibitor, was investigated in the RESONATE trial (NCT01578707), which found long-term benefit of the drug upon 6-year follow-up. The trial also established ibrutinib as the first-line choice for older patients and those without a 17P deletion, thereby demonstrating significant progression-free survival benefit among those high-risk subgroups. However, Duffy noted that ibrutinib is not for everybody.

“If you have a patient with uncontrolled atrial fibrillation, who has a high risk of bleeding that can’t be mitigated, or uncontrolled hypertension despite optimizing therapy management, ibrutinib wouldn’t be my first choice,” Duffy said.

Although the various treatments all need to be evaluated based on unique patient needs, the recent developments for the treatment of CLL are very promising and exciting, Duffy concluded.
“We’re getting to have a better understanding of CLL biology and some of the prognostic indicators,” Duffy said. “These new therapies allow for treatment without some of the traditional chemotherapy agents.”

Immunoglobulin Abnormalities Do Not Affect Overall Survival in CLL, Study Finds

Immunoglobulin Abnormalities Do Not Affect Overall Survival in CLL, Study Finds

This article was originally published by AJMC

Patients with chronic lymphocytic leukemia (CLL) who have immunoglobulin (Ig) abnormalities at diagnosis have shorter treatment-free survival (TFS) periods, but do not have shorter overall survival (OS), according to a new study.

The report, published in the British Journal of Hematology, sheds new light on the ways in which qualitative and quantitative gammaglobulin abnormalities affect—and do not affect—the prognosis of patients with MM.

A team of investigators, including corresponding author Luca Laurenti, MD, of Gemelli University Hospital, in Italy, noted that prior research has looked at the impact of hypogammaglobulinemia in patients with CLL. However, they said there is significant heterogeneity between cohorts, and much research has included both treated and untreated patients, making it difficult to examine the prognostic impact of such abnormalities.

In an effort to get a clearer picture of the impact, the investigators examined 1505 patients with CLL and split them into 4 cohorts based on the degree of Ig aberrations upon diagnosis. The vast majority (1083) had normal Ig levels, making up the largest of the 4 groups. The other 3 groups included 73 patients with IgM monoclonal gammopathy (IgM/CLL), 149 patients with IgG monoclonal gammopathy (IgG/CLL), and 200 patients with hypogammaglobulinemia (hypo-c).

“IgM paraprotein was significantly associated with a more advanced Binet/Rai stage and del(17p)/TP53 mutation, while IgG abnormalities correlated with a higher occurrence of trisomy 12,” the authors said.

Any type of Ig abnormality lowered a patient’s expected TFS, Laurenti and colleagues found, but there was not a corresponding statistically significant impact on OS.

The authors noted that hypogammaglobulinemia specifically has been linked in the past with higher infections and morbidity. Thus, Ig replacement therapy, which was not investigated in this study, is indicated by current guidelines for the management of patients with CLL.

“However, some studies suggest that hypogammaglobulinemia is not associated with a higher risk of death from infections, but rather with a shorter TFS and a higher risk of death from all causes, being primarily a marker of greater tumor burden and reflecting a more aggressive disease,” Laurenti and colleagues wrote.

This hypothesis is supported by the current study, they said.

More broadly, the authors said their 28% rate of Ig abnormalities fell somewhere in the middle of rates reported in existing research, which ranged from 7% to a high of 80%. The investigators also reported that the proportion of patients with each type of abnormality held generally steady across the 4 cancer centers in the study. However, the authors said the rates were somewhat of a surprise.

“Even though we did not perform any characterization of the heavy-chain isotype and considering that CLL cells express breakpoint cluster region proteins (BCRs) mostly of IgM and IgD isotypes, rather than the IgG class, IgM paraprotein was expected to be more frequent but instead the occurrence of IgG monoclonal component was even double than that of IgM,” the authors said.

In conclusion, the authors said while other factors such as IGHV status mutation, Binet/RAI stage, and del17p are known prognostic factors for OS, “Ig alteration does not have any impact on OS.”

CLL Advocates NZ Newsletter Issue 2

CLL Advocates NZ Newsletter Issue 2

A number of you will be familiar with and regularly reading HealthUnlocked and Patient Power, two patient support and networking services (based in the UK and US respectively) that cover CLL in detail.

For those not yet in the habit, I can recommend both websites to CLL patients, and their families and supporters. You can access both through our website on our useful links page here, or go directly to Patient Power here and HealthUnlocked here. Access is free.

HealthUnlocked is published daily, with ten articles in each edition, that are mainly personal stories and discussion among people with CLL, and also occasional reviews of CLL-related clinical studies.

One such study, in the 20 July edition was on CLL and Covid 19. It provided an analysis of the assessment of 190 patients with CLL who had proven Covid 19 infection. Most presenting for analysis (79%) were in the “severe” category (requiring ICU admission and/or oxygen). This is likely to be related to their having had contact with a hospital. One third of these patients died of Covid 19. The severe group were older than the less severe group, so increasing age is a risk. There was a reduced rate of severe disease in those patients who had had treatment recently as opposed to those who had treatment remotely, or never.

Patient Power (PP) sends email updates to subscribers, generally weekly. Their CLL articles tend to have more of a scientific and medical focus. They also regularly post videos of interviews conducted by the PP CEO, Andrew Schorr, who is a long-term CLL survivor. He interviews well known clinicians on aspects of CLL, including the latest research and developments in the understanding and treatment of CLL. His wife, Esther, also writes regularly for PP.

An interesting recent PP article discussed CAR T-cell treatment, which is being trialled for CLL in research centres globally, including the Malaghan Institute in Wellington (Dr Rob Weinkove).

As an aside on CAR T-cell therapy, I recently enjoyed a book by NZ comedian David Downs on his experience with cancer (in his case, lymphoma). The book is entitled “A Mild Touch of the Cancer”. It is humorous and insightful on living with a serious health issue, and I commend it to you.

Finally, if you haven’t already seen it, check out our message on Facebook and on our website about our first CLL education event, to be held in Auckland, on Wednesday 14 October 2020.  The event will be jointly hosted with Leukaemia & Blood Cancer. For those unable to be there in person, you’ll be able to join us via Zoom, to hear talks by and discussion with three of our country’s foremost CLL clinicians. As well as providing the latest information on CLL we hope to extend our reach and ability to support people living with CLL, and I warmly encourage you to help spread the word and attend the event with your family and supporters. More detail on the event including how to register will be circulated soon.

Genetic Prognostic Factors in CLL Treated With Novel Compounds

Genetic Prognostic Factors in CLL Treated With Novel Compounds

This article was originally published by Cancer Therapy Advisor

Treatment with obinutuzumab plus venetoclax (VenG) was associated with improved outcomes compared with obinutuzumab plus chlorambucil (CGlb) among patients with chronic lymphocytic leukemia (CLL) and established unfavorable genetic factors, according to a study published in Blood.1

“Genetic parameters are established prognostic factors in chronic lymphocytic leukemia (CLL) treated with chemoimmunotherapy, but are less well studied with novel compounds,” the authors wrote.

Unmutated IGHV, mutated TP53, and deletion of chromosome 17p (del[17p]) that contains the TP53 locus, are associated with progression and shorter survival among patients with CLL treated with chemoimmunotherapy. Other genetic markers have been identified that are also prognostic for outcomes.

This analysis used data from the multicenter, phase 3 CLL14 trial, which randomly assigned 432 patients with CLL to receive first-line VenG or CGlb. The analysis used fluorescence in situ hybridization (FISH), DNA sequencing, and next-generation sequencing to evaluate genetic prognostic factors.

CLL Experts Favor Social Distancing, but Vary on Treatment Continuation Amid Pandemic

CLL Experts Favor Social Distancing, but Vary on Treatment Continuation Amid Pandemic

This article was originally published by AJMC

A new survey of chronic lymphocytic leukemia (CLL) specialists finds most recommend generally following World Health Organization (WHO) guidelines when it comes to social distancing and testing during the coronavirus disease 2019 (COVID-19) pandemic, but the survey also found some disagreement with regard to whether to continue with therapy.

The survey is the latest attempt to figure out how best to manage patients with CLL amid the pandemic, given that patients with the cancer tend to be older in age, have comorbidities, and be immunosuppressed.

In a letter to the editor of the American Journal of Hematology, corresponding author Mazyar Shadman, MD, MPH, of the Fred Hutchinson Cancer Research Center, in Seattle, and colleagues reported on a survey sent to 62 CLL specialists in the United States, Canada, Europe, and Australia. Of those, 59 responded to at least 1 question, and 44 completed the entire survey.

When asked about social distancing recommendations for patients with CLL, 32% said they would advise patients to follow the same guidelines as the WHO and Centers for Disease Control and Prevention (CDC) recommend for the general public. Twenty-one percent said they would advise patients to follow those guidelines but also limit regular outings by asking friends to pick up groceries or medications for them. Another 35% went even further, saying patients with CLL should avoid work, even if they are essential workers. The remaining 12% said they would recommend all of the above, plus wearing N95 masks and gloves outside of the house.

In terms of testing, most experts said it was not necessary to test all patients with CLL for COVID-19. Specifically, 62% of experts said they would limit testing to patients who call to and report symptoms, and another 9.5% said tests should be limited to patients who come in for an office visit and report symptoms.

Still, while clinicians generally had a low bar for what types of symptoms warranted testing. “Most favored testing patients with any levels of reported symptoms, even with limited testing availability,” Shadman and colleagues wrote. “With unlimited access, 23% recommended universal testing.”

Though their approaches to social distancing and testing were in line with recommendations for the general public, the experts expressed caution when it came to continuation of outpatient therapy. Only 14% said CLL therapy should be continued unconditionally. Most  (60.5%) favored treatment discontinuation, and 25.5% said they favored continuation only based on the specific clinical situation.

However, when it came to bruton tyrosine kinase inhibitors (BTKis), such as ibrutinib (Imbruvica) and acalabrutinib (Calquence), the proportion of experts favoring unconditional treatment continuation was much higher, at 44%.

Shadman and colleagues said the more favorable responses concerning BTKi continuation may be due to concern about disease flares if treatment were stopped.

“Also, there is a theoretical benefit of BTKi’s in blunting the hyperinflammatory stage of COVID-19 disease by targeting macrophages and/or inhibiting pro-inflammatory cytokines,” they said.

Most experts (72%) recommended against the use of intravenous immune globulin (IVIG), though the authors noted that the survey was conducted in late March and early April, “before passive antibodies in the gammaglobulin pool would be expected.”

Shadman and colleagues said additional study is warranted to better understand the optimal approach to management of patients with CLL during the pandemic.

Dr. Davids on the Potential Utility of Frontline Ibrutinib/Umbralisib in CLL and MCL

Dr. Davids on the Potential Utility of Frontline Ibrutinib/Umbralisib in CLL and MCL

This article was originally published by OncLive

Matthew S. Davids, MD, MMSc, an associate director with the Center for Chronic Lymphocytic Leukemia; director of clinical research, Lymphoma Program; and medical oncologist, Dana-Farber Cancer Institute; and an assistant professor of medicine at Harvard Medical School, discusses the potential utility of moving the combination of ibrutinib (Imbruvica) and umbralisib into the frontline setting of chronic lymphocytic leukemia (CLL) and mantle cell lymphoma (MCL).

Findings from a phase 1/1b study presented during the 2020 European Hematology Association Annual Congress showed that ibrutinib/umbralisib elicited high response rates in CLL and MCL with a tolerable safety profile.

Updated data from the study revealed that progression-free survival and overall survival did not differ significantly from ibrutinib monotherapy in patients with MCL; however, outcomes were not negatively impacted.

In CLL specifically, the combination may have utility in the post-venetoclax (Venclexta) patient population as venetoclax is being used earlier in treatment, explains Davids.

Moving PI3K inhibitors into the frontline setting has been met with some challenges such as increased immune-mediated toxicities, says Davids.

As umbralisib appears to be a well-tolerated PI3K inhibitor, this combination may have potential utility in CLL, concludes Davids.

A 79-Year-Old Man With Relapsed Chronic Lymphocytic Leukemia

A 79-Year-Old Man With Relapsed Chronic Lymphocytic Leukemia

This article was originally published by Targeted Oncology

High-Risk Chronic Lymphocytic Leukemia

Jeff Sharman, MD: Hello, my name is Jeff Sharman. I’m the Medical Director of Hematology Research for US Oncology, and I am a practicing oncologist at the Willamette Valley Cancer in Eugene, Oregon.

Today I’ve been asked to present a case of a 79-year-old gentleman with relapsed chronic lymphocytic leukemia to address some of the treatment considerations we have in this patient population.

This particular patient is a hypothetical patient but referred to me. We’ll say that he was a 79-year-old gentleman who initially presented to his outside medical oncologist for the first time complaining of some vague intermittent abdominal pain and progressive fatigue. His past medical history is notable primarily for medically-controlled hypertension. He had a myocardial infarction 8 years ago and is on low-dose aspirin. His original CLL diagnosis was about 7 years ago, and after a period of watchful waiting, he had progressive lymphocytosis and adenopathy. He was treated with ibrutinib 420 mg daily, his symptoms improved, and he achieved a stable disease with resolution of lymphadenopathy.

Unfortunately, after 5 years of disease control on ibrutinib, he complained of increasing fatigue and decreasing appetite. Upon physical exam, he had a return of palpable lymphadenopathy, and his spleen was palpable, 4 centimeters below the costal margin. At that time, seen by an outside medical oncologist, he was started on rituximab monotherapy due to his medical comorbidities, but after 6 months on this regimen, he presents to my clinic after moving to be closer to family.

His physical exam was notable this time for palpable bilateral cervical adenopathy, right-sided inguinal adenopathy. Labs showed a white blood cell count of 55,000, predominately lymphocytes, and neutrophil count of 3100. He was anemic and thrombocytopenic, with a hemoglobin of 9.4 and platelets of 90,000, respectively. His beta-2 microglobulin was elevated, and, notably, he had a creatine clearance of just 31 mL per min.

Flow cytometry confirmed the typical immunophenotype for CLL, and at this time, FISH testing was performed and, importantly, returned a deletion of 17p in a high fraction of the cells. He was Rai stage 4 with an ECOG performance status of 1. At this time, treatment was initiated with idelalisib in combination with rituximab, or I should say idelalisib was added to rituximab at this time, 150 mg PO BID.

Now this is an interesting case, and it presents a number of features that are challenging in terms of how to pick therapy in this population with significant comorbidities. I’ve been asked to address questions pertaining to both his prior management, his current situation, and so forth.

The first question I’ve been asked is to describe my initial impression of the case and what the prognosis was for this patient. You know this is a patient who has high-risk CLL. He has relapsed after ibrutinib, and he has a deletion of 17p. What that means is that chemoimmunotherapy is not going to work for this individual, so you really don’t have that much in the way of options. Then you’ve exhausted BTK inhibitors, and there’s a question of what you have left.

In this particular case, the outside provider used rituximab monotherapy probably for lack of clarity in what options might have been available; this is a patient that because of his age and comorbidities, it’s very possible this patient may ultimately pass away of their CLL, which, in contemporary CLL management, seems like a relatively rare occurrence.

When we discuss risk stratification for patients with chronic lymphocytic leukemia, there’s a couple of things that are really important. We think about their IgHV status, which is really a measurement of how quickly the CLL is growing. What are the kinetics of growth? Then we think about the FISH status, which is how resistant it is to therapy. Deletion of 17p is a particularly noteworthy abnormality because patients with 17p have very brief responses to chemoimmunotherapy-based approaches.

Similarly, we’re seeing updates with targeted therapy, such as venetoclax, that 17p can retain adverse prognostic significance in this population. In this particular patient’s case, idelalisib had been added to the regimen. It’s noteworthy that idelalisib outcomes appear to be independent of 17p, so whether 17p is present or not, the outcomes relative to 17p don’t matter quite as much.

Transcript edited for clarity.

Age, Recent Treatment, Appear to Influence Severity of COVID-19 in Patients With CLL

Age, Recent Treatment Appear to Influence Severity of COVID-19 in Patients With CLL

This article was originally published by AJMC

Patients with chronic lymphocytic leukemia (CLL) who contract coronavirus disease 2019 (COVID-19) face more severe symptoms if they are older, though recent treatment with antileukemic agents appears to have a beneficial, rather than detrimental, effect on outcomes, a new study found. The study also suggests that the presence of comorbidities does not lead to higher mortality rates.

The retrospective analysis is based on 190 patients with CLL who had confirmed COVID-19 cases between late March and late May. The results were published in the journal Leukemia.

Corresponding author Kostas Stamatopoulos, MD, PhD, of the Center for Research and Technology Hellas, in Greece, wrote along with colleagues that CLL is a “paradigmatic example” of a malignancy that has been associated with impaired immune responses to pathogens, which they said could have negative impacts on outcomes when patients with CLL contract COVID-19. The investigators added that antileukemic treatments could further hamper the immune system’s ability to fight off a virus like SARS-CoV-2, though they said it’s not a straightforward proposition.

“On the other hand, the severity of COVID-19 and [multiorgan failure] occurrence seem to be related to clinical and laboratory parameters of inflammatory response (lymphopenia, hypoalbuminemia, higher levels of alanine aminotransferase, lactate dehydrogenase, C-reactive protein, ferritin, and D-dimer) and markedly higher levels of proinflammatory cytokines (interleukin-2 receptor, IL6, IL-10, and tumor necrosis factor-α),” they said. “On these grounds, therapies targeting inflammation (eg, IL6/IL6R antibodies or steroids) have been used and shown potential benefit in full-blown COVID-19 patients.”

In an effort to ascertain a real-world understanding of what patients with CLL who contract the virus should expect, Stamatopoulos and colleagues analyzed the 190 colleagues based on age, gender, and comorbidities; severity of COVID-19; and whether and how long ago they had been treated with antileukemic therapies.

The investigators found a strong majority (151, or 79%) of patients presented with severe symptoms, such as requiring oxygen or admission to an intensive care unit. Patients were more likely to have severe symptoms if they were aged 65 or older.

Recent treatment appeared to make a significant difference. Only 4 in 10 patients with severe symptoms had received antileukemic treatment within the past 12 months. However, among those with mild symptoms, 76.9% had undergone recent treatment. Among those with severe symptoms, the likelihood of hospitalization was lower if they had received therapy with ibrutinib (Imbruvica).

More than one-third (36.4%) of patients with severe symptoms died from COVID-19; versus just 1 of the 38 patients with mild symptoms succumbed.

Stamatopoulos and colleagues noted that the apparent link between age and mortality among patients with CLL tracks with known data from the general population. However, they said comorbidities did not appear to have a significant impact on whether a patient had mild or severe symptoms.

As for the impact of antileukemic therapies, the authors said a disproportionate percentage of their study population had been prescribed bruton kinase inhibitors. Thus, they did not have sufficient data to compare the impact of BTK inhibitors to other types of therapy.

Still, they said their data seems to support the idea that recent antileukemic therapy is beneficial against COVD-19.

“Altogether, these data seem to further underscore the possible protective role of specific targeted therapies against a dismal evolution of the SARS-CoV-2 infection,” they said.

Long-Term Results of Ibrutinib/Umbralisib Show Efficacy in CLL and MCL

Long-Term Results of Ibrutinib/Umbralisib Show Efficacy in CLL and MCL

This article was originally published by Targeted Oncology

Matthew S. Davids, MD, associate director of the Center for Chronic Lymphocytic Leukemia, director, Clinical Research for the Lymphoma Program at the Dana-Farber Cancer Institute, and associate professor of Medicine at Harvard Medical School, discusses the long-term follow-up of a phase 1/1b trial (NCT02268851) for patients with relapsed/refractory chronic lymphocytic leukemia (CLL) or mantle cell lymphoma (MCL) receiving ibrutinib (Imbruvica) and umbralisib.

The initial results were presented early in 2019 with about 2 years of follow-up, showing high rates of response in patients with CLL and MCL, according to Davids. There was good tolerability observed for these patients, and the investigators were able to identify the recommended phase 2 dose for umbralisib of 800 mg combined with the standard dose of ibrutinib.

The challenge with the initial report was that the follow-up for these patients was short, Davids says. The goal of the update at the 2020 European Hematology Association Congress was to present about 4 years of follow-up of the progression-free survival (PFS) and overall survival (OS) of the high-risk patients. The investigators also looked at the rates of complete remission, which increased over time.

For patients with MCL, the median PFS was around 11 months, and the median OS was about 2 and a half years. Davids thinks that this didn’t look much different than ibrutinib monotherapy, and it is hard to tell if there is a difference between monotherapy and this combination.

Davids says the investigators saw the bigger difference in the patients with CLL compared to historical control studies. There was about an 80% 4-year PFS in the high-risk CLL population and a 4-year OS of 90%. There are still many patients on the ibrutinib and umbralisib combination. The data set highlights the efficacy and safety of dual B-cell receptor blockade and warrants further study, he believes.

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
