Message from the Founders
S P R I N G 2 0 1 5 inSights A Quarterly Newsletter from Beat Leukemia With Connor Issue No. 2 Beat Leukemia With Connor is a charitable entity set up with the following main mission: Message from the Founders Dear Friends and Supporters Now in our seventh month of fundraising, we continue to maintain tremendous momentum, surpassing USD150,000 in funds raised for pediatric leukemia research. We are humbled by your generosity and support. In this issue, we share with you an arts-in-medicine program that uses a simple string of beads to define the courage and resilience of children undergoing cancer treatment. You will also find an update on one of the research projects you are supporting through BLWC. Please help us build awareness of the need for funds for childhood leukemia research by sharing this newsletter with your friends and visiting our website. As always, we look forward to hearing from you. With Warmest Regards Conwell Tam & Douglas Beal To improve cure rates for childhood leukemia by funding research that focuses on understanding the origins of the disease using the most advanced medical technology available To fund research on understanding and treating resistant disease, and on developing targeted treatment therapies for childhood leukemia Proceeds go entirely towards childhood leukemia research. No administrative charges are deducted so every cent of your donation will contribute to finding more effective cures for childhood leukemia. To learn more about Connor’s story and the work we do, please visit: www.beat-leukemia-with-connor.com inSIGHTS SPRING 2015 Research Focus Researchers working on a project sponsored by Beat Leukemia With Connor have identified a cytokine receptor that, in mutated form, leads to hyper-proliferation of myeloid cells, taking us one step closer to understanding how leukemia may happen Leukemia is a group of cancers that usually begins in the bone marrow and results in a high number of abnormal white blood cells. These white blood cells are immature, do not function normally and are called blasts or leukemic cells. The exact cause of leukemia is unknown. Without understanding the mechanism through which healthy bone marrow transforms into one which produces leukemic cells, it is difficult to design a treatment protocol that maximizes the cure rate for this disease. What is Leukemia? Clinically and pathologically, leukemia is subdivided into a variety of large groups. The first division is between acute and chronic forms. Acute leukemia is characterized by rapid increase in leukemic blasts. Immediate treatment is required due to rapid progression of the disease. Most childhood leukemia is acute. Chronic leukemia is characterized by slow build-up of blasts. It may take months or years to progress and is more common in older individuals. Leukemia is further subdivided according to which types of blood cells are affected: Lymphoblastic leukemia – the cancerous change takes place in the type of marrow cell that goes on to form lymphocytes, infectionfighting immune system cells. Myeloid leukemia – the cancerous change takes place in the type of marrow cell that forms red blood cells, some types of white cells and platelets. Acute Myeloid Leukemia is further sub-divided into 7 types of leukemia. It is this heterogeneity of disease that makes it difficult to treat, with a lower cure rate than other leukemias. Connor suffered from Acute Megakaryoblastic Leukemia (AMKL) – the form associated with the marrow cells that produce platelets. Individuals with Down Syndrome (DS) carry increased risk of developing leukemia, and the form they suffer from are classified as DSAMKL. Researchers know that DS-AMKL is associated with a mutation in a protein called GATA1. GATA1 plays a role in red blood cell development by regulating the switch from fetal hemoglobin to adult hemoglobin. Mutations in the GATA1 gene have been linked to several diseases, including DS-AMKL. From Transient Leukemia to DS-AMKL Another form of leukemia also unique to individuals with DS is Transient Leukemia (TL). TL is of fetal origin (acquired from birth) and is characterized by GATA1 mutation. Most cases of TL resolve spontaneously without treatment, however 20-30% of children with TL go on to develop DS-AMKL within the first 4 years of life. The factors or additional mutations that underlie this progression remain elusive. One of the projects that Beat Leukemia with Connor sponsors aims to identify the mutations in this progression from TL to overt AMKL. Research . Hope . Cure inSIGHTS SPRING 2015 This project, led by Dr. Jan-Henning Klusmann of the Hannover Medical School, uses Next Generation Sequencing (NGS) to identify additional mutations in DS-AMKL. Thereafter, researchers characterize the biological impact of the mutation in functional studies to understand the pathogenesis of the disease and to develop targeted and less toxic therapeutic approaches to DS-AMKL. The ultimate goal of the project is to identify ways to prevent progression from TL to DS-AMKL. The project also has broader implications for other forms of leukemia. It is conceivable that if researchers can understand the mechanism through which one type of leukemia can remain latent over a period of time and then present as another type, the exact causes of leukemia can be identified and in the future, certain types of leukemia maybe preventable. Project Update Researchers have now successfully completed the functional in-vitro (i.e. in the petri dish) evaluation of one gene that is found to mutate in DS-AMKL. This gene is a cytokine receptor, a protein that controls proliferation of myeloid cells. In healthy marrow, the activity of such receptors is controlled by three different cytokines. However, our researchers have found that a mutation in this gene causes the cytokine receptor to act independently, without the presence of cytokines. This leads to the growth of cells in the absence of cytokines. Additional tests done by the research team on hematopoietic stem cells conclude that the mutated form of the cytokine receptor leads to a hyper-proliferation of myeloid cells. Researchers will conduct in-vivo (mouse transplantation) studies in the next stage of the project. Additional Research Update Researchers have concurrently completed analysis of data collected from an 8-year worldwide study on AMKL. An interesting observation was that several patients without any feature of DS had Trisomy 21 as well as GATA1 mutation in their blasts. Some had Trisomy 21 mosaicism in a fraction of their cells, while others acquired Trisomy 21 only in the AMKL blasts. These observations will be used to plan a follow-up study. Dr. Med. Jan-Henning Klusmann Dr.Klusmann is Fellow of Pediatric Hematology and Oncology at the Hannover Medical School. He heads up the Emmy Noether Junior Research Group, which aims to understand the molecular basis for the development of myeloid leukemia (AML) using stateof-the-art molecular techniques. The focus of the group’s research is children with Down Syndrome, who are highly predisposed to develop AML. Dr. Klusmann has been awarded a number of professional distinctions, including the ASH Outstanding Abstract Achievement Awards and the Leukemia Clinical Research Awards 2011 by the German Society of Hematology and Oncology.

Cure inSIGHTS SPRING 2015 Courage and Resilience on a String When Connor began leukemia treatment in Germany, we met children in the pediatric oncology ward with long colorful strings of beads hanging on their IV stands. We did not know what the beads represented but little did we realize Connor would soon have his own string of beads and that after his death, his “beads of courage” would become a remembrance of his life, courage and resilience. What are these beads? The concept of “beads of courage” originated in the United States and was developed and piloted by Jean Baruch at Phoenix Children’s Hospital in February 2003. The key premise of the initiative was, through arts-in-medicine, to support and strengthen children and families coping with cancer. Through the program, children tell their individual stories using colorful beads as meaningful symbols of courage that they receive to honor and acknowledge each step of their treatment journey. Since 2003, the program has reached globally, serving as inspiration for similar resilience-based intervention in children’s hospitals around the world. Whilst the beads may be glass or rubber, and carry different names across the world (for example, “Mutperlen” in Germany, “KanjerKetting” in the Netherlands, “Rainbow Trail” in Scotland, “Beads of Courage” in the US and Canada), all programs serve the same fundamental purpose: to support children fighting cancer, and to help children find meaning in illness. How does it work? A child diagnosed with cancer gets, at admission to the hospital, a wax rope, a bead with an anchor (a sign of hope) and alphabet beads that form the child’s name. Depending on the therapies and treatments, a variety of beads will follow in the next few months or years. Each bead symbolizes an engagement, a milestone, a treatment, a particularly good or bad day. There are small red beads for every blood draw, a small purple and white ball for every bone marrow aspirate. The Chemo-Kasper bead is awarded at the start of every chemotherapy block and a bead in the shape of a hat is awarded for hair loss. There are more than 40 types of beads covering a wide range of treatment milestones: Logistics: admission to the hospital or to the ICU, being in isolation etc. Diagnostics: lumbar punctures, scans, bone marrow aspirates etc. Treatment: chemotherapy, radiotherapy, stem cell transplant etc. Supportive treatment: blood transfusions, nebulizers, nasogastric tubes etc. Other events: birthdays, hair loss, a good day, a bad day etc. Research . Hope . Cure inSIGHTS SPRING 2015 The string of beads grows longer, becoming a “rainbow trail” that represents the personal story of the child. Recognizing that some children may die despite treatment, there is a bead that marks the end of life What do the beads achieve? Healthy children have concrete ways to measure achievements in school or on the soccer field. Children fighting cancer frequently spend months or years struggling with how to define the monumental milestones they achieve and the exceptional bravery they show. The string of beads achieves the purpose of telling each child’s story and is a unique personal diary for the duration of the treatment. Treatments and interventions translate into achievements and concrete proof of the fight against cancer. They give children colorful moments in the cancer ward, help them to stay strong and motivated throughout treatment and deal with disease in a positive way. The beads provide an opportunity for children to talk to other patients in the cancer ward, and are used to explain to family members what happened during treatment. Most importantly, the children are proud of their “beads of courage” – they know the meaning of each bead and exactly what each stands for. VOKK & KanjerKetting The beads program KanjerKetting, as we knew it in Germany, was developed by Vereniging Ouders, Kinderen & Kanker (VOKK or “The Dutch Childhood Cancer Parent Organization”) after in-depth research on the effectiveness of the beads in a pediatric oncology setting. Today, KanjerKetting is adopted by many children’s hospitals across Europe. Beads are given to hospitals free of charge. Children and families also receive the beads free of charge. To learn more about VOKK and KanjerKetting, please visit www.vokk.nl and www.kanjerketting.nl Connor’s Beads of Courage Today, 9 months after Connor’s death, we continue to treasure his beads of courage. We remember the moments we threaded the beads together, we remember the delight on his face when he was awarded a colorful bead for completing yet another session of radiotherapy or despite the tears and pain of his seventh lumbar puncture. The beads are a concrete reminder of his courage and resilience, an immense source of pride for his achievements despite the fight he lost. We are thankful that organizations such as VOKK continue to promote programs like KanjerKetting, and hope that children’s hospitals around the world continue to bring this initiative to families and children suffering from cancer.
