Initial treatment for myeloma Myeloma UK Patient and Family Infoday, Leeds 16th March 2013 Dr Andrew Chantry Senior Clinical Lecturer in Haematology, Dept of Oncology, University of Sheffield/ Honorary Consultant in Haematology, Sheffield Teaching Hospitals NHS Foundation Trust Multiple myeloma – 10% of all haem cancers; second commonest haematological cancer Cancer of white blood cells, known as plasma cells, • Progressive bone marrow failure • Monoclonal gammopathy • Renal failiure • Osteolytic bone disease – osteoporosis c vertebral wedge fractures, spinal cord compression, lytic lesions, pathological fractures, hypercalcaemia, pain and grossly reduced mobility ‘Mollities Ossium’ (Dr Samuel Solly 1846) • In May 1840, Sarah Newbury experienced severe back pain while stooping and a strange sensation in her right leg. • She was given an infusion of orange peel and a rhubarb pill. • Sections of the bones revealed ‘a red grumous matter’; the red matter was examined by Dr Solly and Mr Birkett of Guy’s Hospital; the majority of the nucleated cells had a clear, oval outline and one or rarely two bright central nucleoli Calico Hills Burial #2 (AD 2900) Dr Henry Bence Jones, renowned chemical pathologist at St George’s Hospital, was consulted on a second notable case • Thomas McBean , ‘a grocer of temperate habits and exemplary conduct’ presented with fatigue and a stooped gait • While vaulting out of an underground cavern on his country vacation, he suddenly felt as if something had snapped or given way within his chest and for some minutes he lay, unable to stir because of severe pain. • Treated with acetate of ammonia, camphor julap and compound tincture of camphor. • Died in 1846 – cause of death ‘atrophy by albuminuria’. Henry Bence Jones ‘Dear Dr Jones, The tube contains urine of very high specific gravity. When boiled it becomes slightly opaque. On the addition of nitric acid, it effervesces, assumes a reddish hue, and becomes quite clear; but as it cools, assumes the consistence and appearance which you see. Heat reliquifies it. What is it?’ (Dr Thomas Watson , GP, Calico Hills Burial #2 (AD 2-to Dr Henry Bence Jones, 1847) 900) Prehistoric multiple myeloma – Red Indian artefacts Calico Hills Burial #1 (AD 2-900) Calico Hills Burial #2 (AD 2900) Calico Hills Burial #2 (AD 2-900) Sowell Mound Skull (approx AD 610) Morse, D et al, NY Acad Med, 1974 Approximately 60% of pts with myeloma present with evidence of bone disease; 8080-90% pts with myeloma bone disease at some stage of their disease (Coleman 1997; Kariyawasan et al. 2007) Norma l Myeloma ‘pepper pot skull’ If it wasn’t fractured before… Fracture risk 16x higher than expected (Melton et al 2005) Spinal cord compression – up to 5% of all patients with myeloma at some stage (Kyle et al 2003) Mechanisms of myeloma bone disease CFU-GM + Mesenchymal Stem Cells Plasma cells Pre-osteoclast + • RANKL • MIP 1-α • Il-3 - + Osteoclast activating factors Osteoprogenitor Osteoblast inhibitory factors Osteoclasts Osteoblasts Bone • Dkk-1 • sFRP-3 • HGF • TGF-β1 These targets validated in our studies; working towards personalised therapy The result – bones is destroyed CFU-GM + Pre-osteoclast Mesenchymal stem cells Plasma cells + + Normal Osteoclasts Bone Myeloma Myeloma – close up At presentation • 15% patients have no symptoms • 38% emergency presentation - Kidney failure - Spinal cord compression/loss of movement - Fracture • Remainder have symptoms - Backache or bone pain - Tiredness/anaemia Decision to treat • Is the myeloma causing symptoms? - unwell, tiredness, pain, frequent infections • Is the myeloma causing organ damage? - kidneys, bone marrow, bone, hypercalcemia • Are there other medical problems or individual issues to consider? Asymptomatic myeloma • Diagnosis does not automatically mean that treatment must start • Good reason to wait until symptoms develop - regular monitoring of paraprotein, blood counts, kidney function etc • No symptoms but blood tests show progression - judgment when to start treatment - joint decision Aims of treatment Anti-myeloma treatment: Reduce myeloma activity and related damage Supportive treatment: Relieve symptoms and complications Reduce symptoms and complications Improve quality of life Prevent further bone and other organ damage Prolong survival Successful treatment should… • Reduce tumour burden and induce longest possible remission/plateau • Achieve maximum response with the minimum of side-effects • Relieve pain and address other symptoms • Prevent further damage to the body • Improve and preserve quality of life for as long as possible Treatment approach Diagnosis Asymptomatic myeloma Symptomatic myeloma Regular monitoring Are you a candidate for stem cell transplant Yes Induction treatment, stem cell transplant Clinical study No Non-intensive drug treatment Treatment decisions: Doctor’s perspective Patient needs & priorities Disease Features Treatment recommendation Evidence & Guidelines Patient Features Prior Treatment & Response Treatment decisions: • What are my options? • What are the side-effects • What should I expect? • How long does treatment last? Practicalities • How does the myeloma affect me? • What’s my goal, what do I want? • How will I expect to feel? Treatment Options Disease & Prognosis Patient’s perspective • Do I have to stay in hospital? • Can I still work? • How far do I have to travel & what time? • Can you help with money? Your consent to treatment should be an informed one Drugs used to treat myeloma 1950s - 60s • Melphalan (+ prednisolone) • High-dose dexamethasone 1970s - 80s • Combination chemotherapy - VAD (vincristine, adriamycin, dex) • High-dose chemotherapy • Bone marrow/stem cell transplantation 1990s - 2000s • Thalidomide • Velcade • Revlimid 2010s - • Carfilzomib, pomalidomide? ‘Novel agents’ Which combination?

VCD Assess response Assess response TRANSPLANT IF APPROPRIATE Randomise No maintenance Revlimid maintenance Rev + vorinostat maintenance • Does Revlimid or Rev + vorinostat maintenance improve survival Treatment options: Non-transplant patients Thalidomide-based • CTD Velcade-based • VMP Cyclophosphamide Thalidomide Dexamethasone • MPT Velcade Melphalan Prednisolone Max 8 cycles Melphalan Prednisolone Thalidomide Max 8 cycles As per NICE guidance Supportive • Bisphosphonates Zometa, pamidronate, Bonefos • Blood transfusions/EPO • Pain-killers • Anti-thrombotic Treatment options: Transplant patients: Step 1: Induction treatment Step 2: High-dose therapy and stem cell transplant - Autologous (own stem cells) – vast majority - Allogeneic (donor stem cells) – very small minority Step 1: Induction treatment Thalidomide-based • CTD Cyclophosphamide Thalidomide Dexamethasone Max 8 cycles – must have partial response or better Velcade-based • PAD Velcade Adriamycin Dexamethasone Max 6 cycles Supportive • Bisphosphonates Zometa, pamidronate, Bonefos • Blood transfusions/EPO • Pain-killers • Anti-thrombotic Step 2: High-dose therapy and stem cell transplant 1. Stem cell mobilisation 2. Stem cell collection 4. Stem cell transplant 3. High-dose melphalan Maintenance treatment? • Continuous treatment after initial treatment • Role of maintenance treatment still under debate • Interferon – prolongs remission by ~6 months but difficult to tolerate • Thalidomide – may benefit some patients • Revlimid – promising data, increasing length of remission and overall survival, however, increased risk of second cancers Remission – current practice • • • • No treatment, most drugs stopped Maintenance treatment – not standard Bisphosphonates for at least 2 years Minimal effective pain management 100 50 20 1st REMISSION Summary • Myeloma is an individual cancer - requires a personalised approach • Patients should have a role in their treatment plan important to discuss goals and perceptions • Various treatment combinations are effective and generally well tolerated • But, it remains a difficult and challenging disease • More research required to understand and develop better treatments and better ways of using existing treatments Healthy Mouse Bone Mouse bone with myeloma Mouse bone with myeloma plus Anti Dkk-1 Chantry et al, JBMR 2009 For information: www.myeloma.org.uk 0800 980 3332
