22. Key Takeaways
MM is a malignant proliferation of a single clone of
plasma cells that arise from B cells in the bone marrow
Most patients present with bone pain and anemia
Cytogenetic evaluation of the bone marrow is important
for risk stratification and management of the disease
The myeloma panel should be monitored closely to
evaluate response to therapy or relapse disease
Diagnosing MM at an early stage prevents organ
damage such as renal failure and fractures

24. Case Study
60-year-old man
July: Chest pain, dyspnea. A stent was placed for
coronary artery disease. Placed on an antiplatelet agent.
August: Developed hematuria and proteinuria. Treated
for UTI.
November: Severe mid and lower back pain without
trauma. Fatigue “no better since stent.” UA/C&S: 2+
proteinuria, hematuria; no bacteria.
UPEP: Immunofixation positive for kappa light chains
UTI = urinary tract infection; UA = urinalysis; C&S = culture & sensitivity.
26. Case Study: CRAB Criteria?
Related organ or tissue involvement (CRAB)
– Calcium > 11.5 mg/dL, actual value: 14.3 mg/dL
– Renal (creatinine > 2 mg/dL), actual value: 3.1 mg/dL
– Anemia (Hgb < 10 g/dL or 2 g/dL below LLN), actual: 7.7 g/dL
– Bone/skeletal survey: Diffuse abnormal appearance of the pelvis. 2 large
lytic lesions right femur. Calvarial lesions.
Additional testing? Calvarium
Femur
– BMB cytogenetics, FISH
– “Myeloma labs”
(SPEP, UPEP, sFLC)
LLN = lower limit of normal.
27. Case Study:
Bone Marrow and MM Studies
Bone marrow plasma cell infiltration: 20%
Myeloma FISH panel: Not performed; Cytogenetics: 46,XY
ISS stage: Albumin: 3.6 g/dL, β2m: 6.0 mg/L (III)

– Serum kappa free light chains: 3014.0 mg/L
– Urinary M protein: 2.81 g/24 hrs
Diagnosis: Symptomatic MM kappa light chain type
Does this patient require treatmennt for MM?
28. Considerations:
Initial or Induction Therapy
Induction chemotherapy
– Treatment given to “induce” a response
The ideal initial or induction therapy should
– Rapidly and effectively control disease
– Reverse disease-related complications
– Decrease the risk of early death
– Be easily tolerated with minimal/manageable toxicity
– Not interfere with the ability to collect stem cells for
transplantation (if a transplant candidate based on age, desire,
health status)
Kumar et al, 2009.
29. Should All Patients Receive
Induction Chemotherapy?
Spectrum of Plasma Cell Dyscrasias
Low M component, no CRAB High M component, no CRAB CRAB
MGUS Smoldering MM MM
Only patients with symptomatic MM (CRAB) require treatment
Evidence that patients with “smoldering” MM can benefit from early
treatment with lenalidomide + dexamethasone
– This should only be recommended in the context of a clinical trial
A percentage of patients with MGUS may never require treatment
– Increased sFLC ratio, higher M protein may indicate a group more likely
to progress to symptomatic MM
3 key agents given today: Bortezomib, lenalidomide, and
thalidomide in combination with corticosteroids
Mateos et al, 2011; Khoriaty et al, 2010; Rajkumar et al, 2005.
30. Initial or Induction Therapy for MM:
Transplant Eligible and Ineligible
Transplant Ineligible Transplant Eligible
Melphalan +/- Induction Therapy
• Bortezomib Non-Alkylator Based
• Lenalidomide
• Thalidomide
• Other Early Delayed
Autologous Autologous
Transplant Transplant
Supportive care should be considered at diagnosis and throughout
NCCN, 2012; Kumar et al, 2009.
31. How Do You Treat MM: Specific Doses

Bortezomib + Bortezomib 1.3 mg/m2 SC/IV Days 1, 4, 8, 11 +
dexamethasone Dexamethasone 20 mg PO Day 1, 2, 4, 5, 8, 9, 11, 12
(+ cyclophosphamide,
lenalidomide, or thalidomide)
Lenalidomide + Lenalidomide 25 mg PO Days 1–21, q28d +
dexamethasone Dexamethasone 40 mg PO wkly (+ bortezomib 1.3 mg/m2 wkly or BID?)
(+/- bortezomib?)
Thalidomide + Thalidomide 200 mg PO Days 1–28 +
dexamethasone Dexamethasone 40 mg PO Days 1–4, 9–12, 17–20 x 4 28-day cycles
(+ bortezomib or PLD?) (+ bortezomib or PLD?) – LESS COMMON TO GIVE THAL UPFRONT
Non-Transplant Candidate
Any of the novel agents
Prednisone is often substituted for dexamethasone (elderly poor tolerance)
Melphalan + any of MPV: 9 6-wk cycles of melphalan 9 mg/m2 PO + prednisone 60 mg/m2 PO Days 1–4 and/
the above or bortezomib 1.3 mg/m2 on Days 1, 4, 8, 11, 22, 25, 29, 32 during Cycles 1–4 and Days
1, 8, 22, 29 during Cycles 5–9
Maintenance May improve PFS; ongoing studies
PO = oral; MPV = melphalan, prednisone, bortezomib; PLD = pegylated liposomal doxorubicin; PFS = progression-free survival.

Thalomid® prescribing information, 2012; Velcade® prescribing information, 2012;
Revlimid® prescribing information, 2011; Palumbo et al, 2011.
34. Important Considerations in MM:
Bone Disease
Malignant cells produce osteoclast-activating factors
(hormones, cytokines) that destroy bone cells
– Leads to osteolysis, bone pain, and pathologic fracture
BP (pamidronate, zoledronic acid) inhibit bone
destruction
– Monitor patients for
• Acute phase reactions (flulike sxs, chills)
• Renal dysfunction
– Dose reduce BP for decreased CrCl, longer infusion time
– Monitor for albuminuria, a sign of tubular damage
• Osteonecrosis of the jaw (ONJ)
– Baseline and ongoing dental exams
– Hold BP if jaw pain
BP = bisphosphonates; CrCl = creatinine clearance; ONJ = osteonecrosis of the jaw.
Tariman et al, 2010; Kyle et al, 2007; Morgan et al, 2010a.
35. Important Considerations in MM:
Infections
A leading cause of death in myeloma patients
Ig levels decreased (hypogammaglobulinemia)
Infiltration of bone marrow by plasma cells
Cytotoxic therapy, transplant and glucocorticoids
Interventions
– Prompt reporting of symptoms
– Intravenous immunoglobulin (IVIG) prophylaxis for frequent infections
– Poor response to pneumococcal and influenza vaccines
– Herpes zoster oral prophylaxis (bortezomib)
Barlogie et al, 2006; Durie at al, 2003; Malpas et al, 2004; NCCN, 2012.
36. Important Considerations in MM:
Peripheral Neuropathy
Damage to the peripheral nervous system caused by injury, inflammation, or
degeneration of peripheral nerve fibers (sensory, motor, autonomic)
Incidence of CIPN is increasing
– More neurotoxic drugs have been developed, patients are living longer
Thalidomide and bortezomib (vincristine, cisplatin less commonly used)
Sensory, motor, autonomic
Signs and symptoms: Numbness, tingling, pain
Monitoring: Symptom assessment, test sensation, DTRs, gait, proprioception
Grade 1 Grade 2 Grade 3 Grade 4
Peripheral Sensory Asymptomatic; loss Moderate symptoms; Severe symptoms; Life-threatening;
Neuropathy of reflexes limiting instrumental limiting selfcare urgent intervention
ADLs ADLs indicated
If pain: Reduce 1
level or change to Hold and/or reduce
wkly STOP
ADLs = activities of daily life; CIPN = chemotherapy-induced peripheral neuropathy; DTR = deep tendon reflexes.
Tariman et al, 2008; Wickham, 2007; Thalomid® prescribing information, 2012; Velcade® prescribing information, 2012;
NCI.v4.0 (CT-CAE), 2009; Richardson et al, 2011.
37. Venous Thromboembolic Events
(VTEs) in MM
MM is an intrinsically hypercoagulable disease
associated with a higher risk of thromboembolic events
Higher risk for DVT/PE in patients treated with
conventional chemotherapies plus novel therapies
(thalidomide, lenalidomide)
– Prior VTEs, surgery, immobility, obesity require LMWH/warfarin
– All patients should receive ASA unless contraindicated
Dx: Duplex ultrasound, spiral CT if PE suspected
Prevent: Ambulate, SCDs, antiembolism stockings
(questionable benefit), exercise
Prophylaxis if high risk as above
PE = pulmonary embolism; SCD = sequential compression device; LMWH = low molecular weight heparin;
ASA = acetylsalicylic acid.
Rome et al, 2008; Musallam et al, 2010; Menon et al, 2008.
38. Side-Effect Assessment and Management
Individualized for Each Patient
What is the risk of VTE? Increased if prior VTE, receiving IMiDs, etc.
Bone health Are bisphosphonates indicated?
Infectious diseases Is your patient at high risk for – Wkly CBC, differential for
infection? 8 wks with lenalidomide
(myelosuppression from – Acyclovir prophylaxis with
disease/treatment)
bortezomib
– IV Ig for recurrent
infections (a result of
hypogammaglobulinemia)
GI Antiemetic prior to bortezomib, Assess for diarrhea,
doxorubicin constipation
PN Review increased risk of PN with Prompt intervention can
bortezomib and thalidomide prevent irreversible PN
symptoms
Monthly monitoring of SPEP, UPEP, 24-hr urine, sFLC
disease parameters
IMiDs = immunomodulatory drugs.
IMF, 2011; Kyle et al, 2007; NCCN, 2012; Smith et al, 2008.
39. Bortezomib:
New Data on Survival, Dosing

to next
Patients randomized to 9 6-wk
treatment
cycles of MP plus bortezomib
(VMP) or to MP alone
Wkly bortezomib: Significantly less severe PN (3%)
New evidence for dosing of
compared with twice-wkly IV without a change in
bortezomib
– Once-wkly IV response
– SC
Bortezomib SC is not inferior to IV by overall
response rate
MP = melphalan, prednisone; OS = overall survival; TTP = time to progression. Bortezomib SC not different from IV by
San Miguel et al, 2011; Moreau et al, 2011.
40. Lenalidomide:
New Data on Safety, Efficacy
Similar to bortezomib, oral lenalidomide remains a
common treatment for patients with newly diagnosed
MM (transplant eligible or ineligible)
Tumoricidal and immunomodulatory
Non-transplant: MPR-R vs. MPR vs. MP
– Continuous MPR-R reduced risk of progression,
maintenance improved PFS 31 mos
Lenalidomide post-transplant maintenance improves
PFS (compared to placebo)
MPR = melphalan, prednisone, lenalidomide; MPR-R = MPR plus lenalidomide maintenance.

4) Bisphosphonates, acyclovir
5) None of the above
45. Key Takeaways
There is no‘gold standard’treatment for MM
Newer agents provide improved response rates,
improved survival
Nurses play an important role in side-effect recognition,
management
Newer dosing strategies can decrease side effects
Personalized care plans are necessary for all patients
46. The Evolving Landscape of Myeloma
Treatment: Maintenance Therapy

47. Case Study: Maintenance
Mr. P is a 48-year-old with newly diagnosed IgG Kappa
multiple myeloma
M spike at diagnosis: 5.2 g/dL
CRAB features at presentation
– Renal insufficiency (creatinine 2.8 mg/dL)
– Anemia (Hgb 8.8 g/dL)
Receives 4 cycles of induction chemotherapy with
bortezomib and dexamethasone and undergoes ASCT
Would he be a candidate for maintenance therapy?
ASCT = autologous stem cell transplant.
48. Maintenance Therapy
Maintenance therapy is the use of ongoing low intensity
chemotherapy to eliminate or suppress the minimal
residual tumor clone over a prolonged period of time
Maintenance therapy is administered when the disease is
in remission, either undetectable or at a low level
The purpose of maintenance therapy is to prolong
remission duration and thereby, life expectancy
Immunomodulatory molecules are well suited for
maintenance therapy, as they can be administered orally
at low doses for a prolonged period of time
49. Thalidomide Maintenance After ASCT

61. Case Study: Maintenance
Conclusion
3 months following ASCT, Mr. P achieved a PR (80%
reduction in serum m protein)
– M spike 0.49 g/dL
Renal insufficiency and anemia resolved
– Creatinine normal 0.8 g/dL
– Hbg 13.4 g/dL
Would he be a candidate for maintenance therapy?
ANSWER: Yes (based on data presented)
Began maintenance with lenalidomide 10 mg po daily
62. Key Takeaways
Maintenance therapy delays recurrence of myeloma and
prolongs PFS
Chronic low dose oral agents are preferable for
maintenance strategy
Bortezomib and lenalidomide are better suited for high-risk
disease
There is a slight increase in incidence of second
malignancy after lenalidomide maintenance following
melphalan
New agents may be appropriate for maintenance studies
– Carfilzomib, pomalidomide, oral proteasome inhibitors (MLN9708,
ONX0912)

Myeloma Treatment:
Relapsed/Refractory Disease
Beth Faiman, PhD(c), MSN, APRN, BC, AOCN®
Cleveland Clinic Taussig Cancer Institute
64. Case Study: Mr. P (cont.)
Mr. P remains on lenalidomide 10 mg po daily for 3 years
Develops lower back pain and worsening anemia
Bone survey
– L2 vertebral compression fracture and calvarial lesions consistent
with disease progression
Labs
– M spike February 2012: 0.95 g/dL
– M spike March 2012: 1.32 g/dL (confirms disease progression)
– Hgb 9.2 g/dL, creatinine 1.3 mg/dL
Mr. P has relapsed myeloma
What are his treatment options?
65. How Is Relapse Defined?
Relapse is defined as reappearance of signs and
symptoms of the disease or signs of increasing disease
and/or end organ dysfunction (MDE) that are felt related
to the underlying myeloma
1) Reappearance or increase in paraprotein serum and/or urine – serum
M spike, sFLC or BJP in urine
2) Development of new soft tissue plasmacytomas or bone lesions or
increase in the size of existing lesion on imaging
3) Hypercalcemia
4) Development of anemia
5) New or worsening kidney function
6) Hyperviscosity requiring therapeutic intervention
MDE = myeloma-defining event; sFLC = serum free light chain; BJP = Bence Jones protein.
Lonial, 2010; Bird et al, 2011; Anderson et al, 2008.
66. When Do You Treat Relapsed
Myeloma?
Symptomatic relapse
– CRAB symptoms: HyperCalcemia, Renal impairment,
Anemia, Bone lesion, new plasmacytoma, bone lesions
Clinically significant relapse
– Doubling of paraprotein
• (M spike > 1 g/dL, BJP > 500 mg/day, sFLC level > 200
mg/L)
Asymptomatic biochemical relapse should not be treated
Goals: Control of disease, decrease morbidity
Nurses can ensure ongoing evaluation for risk of VTE,
skeletal events, infections, neuropathy
Bird et al, 2011; Anderson et al, 2008.
67. How Is Refractory Disease Defined?
Refractory disease should fulfill all of the
following criteria
– Should have failed > 2 lines of therapy
– Should have PD after treatment with all 4 classes of
drugs
• Cytotoxic agents (melphalan, cyclophosphamide,
anthracyclines, bendamustine)
• Immunomodulatory agents (thalidomide, lenalidomide)
• Proteasome inhibitor (bortezomib)
• Glucocorticoids (prednisone, dexamethasone)
– Should be progressing on the last line of therapy or
within 60 days of discontinuing treatment
PD = progressive disease.
Lonial, 2010; Anderson et al, 2008.
68. Considerations in Relapsed MM
Disease related
– Indolent, slow, or single site relapse
– Rapid and multiple sites of relapse
– Extramedullary disease, CNS, plasma cell leukemia
– Additional genetic changes
Patient related
– Poor performance
– Poor renal function
– Poor hematopoietic reserve
Treatment related
– Prior drug exposure (relapsed or PD on therapy)
– Ongoing toxicity from prior therapy
CNS = central nervous system.
Mohty et al, 2012; Richardson et al, 2010; Lonial, 2010.
69. Treatment of Relapsed Myeloma:
How Do We Decide?
Existing novel agents
– Thalidomide, bortezomib, lenalidomide
Existing older agents
– Dexamethasone, prednisone, cyclophosphamide,
melphalan, anthracyclines
Clinical trial options
Single agent vs. combination

after 3 months of therapy
Side effects of myelosuppression were mild and controlled
with appropriate dose adjustments
He continues on therapy per clinical trial protocol until
relapse
81. Key Takeaways
The overall survival of patients with MM has increased
within the last decade
Many new treatments have become available
The diagnosis of MM has transitioned to a chronic
disease thus supportive care must be ongoing
Future research is directed at newer targets using a
more “novel” approach

Editor's Notes
B cells mature to plasma cells and produce antibodies and immunoglobulins to fight infection. When multiple myeloma occurs, these plasma cells become malignant and an overproduction of a single clone occurs. Myeloma cells infiltrate the bone marrow and result in bone destruction, lytic lesions, fractures, hypercalcemia, anemia and renal dysfunction. CRAB: Calcium- hypercalcemia due to bone destruction Renal- renal insufficiency or renal failure due to myeloma kidney Anemia- poor production of RBCs Bone impairment- References: Kyle RA., Rajkumar SV., 2009.

The exact cause is unknown. Risk factors include those 65-70 years old; it ’s twice as likely to occur in African Americans than Caucasians; and more common in men than women. Genetics is also a factor as those with a first-degree relative with MM are at higher risk; External and environmental exposures are also a risk factor including ionizing radiation, pesticides and petroleum. Other factors include obesity and chronic immune diseases i.e. systemic lupus. References: Kyle and Rajkumar, 2012. Multiple myeloma. Bope and Kellerman: Conn's Current Therapy 2012, 1st ed.

When MM is suspected, it ’s important to obtain a complete history and physical; there are certain laboratory test and imaging that are very important at baseline A bone marrow biopsy should include: Immunophenotyping: flow cytometry used to study the protein expressed i.e. CD138 , CD 38 and CD56. Conventional cytogenetics- chromosome analysis (abnormal aberration and deletions i.e. ) and karyotype (includes the number, size, shape or chracteristics of the chromosomes) Fluorescence in situ hybridization (FISH): Genetic mapping using fluorescent tags; analysis of chromosomal aberrations and genetic abnormalities (translocations) i.e. 13q & 17p deletion; t(4:14) & t(14;16) Plasma cell labeling index: slide-based immunofluorescent assay; rapid tumor cell division; prognostic factor References: Kyle and Rajkumar, 2012.

Oncologic emergency: cord compression requiring immediate intervention (radiation). Nuclear bone scans are considered less sensitive than radiographs in most parts of the skeleton. It is useful in evaluating bone metastasis i.e. in breast cancer. Bone scans may yield negative results in the presence of disease in patients with MM. A skeletal survey sometimes called a myeloma survey is preferable in evaluating the extent of bone disease in patients with MM. References: Dispenzieri A., Lacy M., Greipp P., 2009. Multiple Myeloma.

July 2010 he developed chest pain and dyspnea, found to have CAD. A stent was placed into the LAD. On antiplatelet agents he developed hematuria and was then found to have a kidney cancer that was resected in January 2011. After the surgery he developed severe pains in his feet and was felt to have gout. He was treated with colchicine, which helped. Once the gout was better he developed severe mid and lower back pain without trauma. He was prescribed cyclobenzaprine , then an NSAID by his PCP but did not take a lot of the latter. When he went back to see his PCP in March his creatinine and calcium were elevated. He was found to have a monoclonal protein.
Notice anemia, elevated creatinine and hypercalcemia
This patient qualifies for CRAB diagnosis. See the large lytic lesions in his femur and lesions in calvarium
Creatinine was elevated but there was no kidney biopsy since he has only one kidney and a strong suspicion to treat for cast nephropathy. Based on the labs above, would this gentleman require treatment for MM? Yes
The key point of this slide is to describe induction chemotherapy. This slide also depicts considerations a few of the many considerations when deciding upon initial therapy
Not everyone requires treatment. The most recent results of a Spanish Phase 3 clinical trial indicate that Revlimid in combination with dexamethasone delays disease progression in smoldering multiple myeloma patients who have a high risk of developing symptomatic disease. Specifically, the results showed that high-risk smoldering multiple myeloma patients who received Revlimid plus dexamethasone had a longer time to disease progression and better overall survival than patients who did not receive treatment. These results should be confirmed by long-term follow-up data, especially regarding the difference in overall survival. Abstract 303: Smoldering Multiple Myeloma (SMM) is an asymptomatic proliferative disorder of plasma cells (PCs) defined by a serum monoclonal component (MC) of 30 g/L or higher and/or 10% or more plasma cells in the bone marrow (BM). There are several risk factors predicting high-risk of progression to symptomatic disease: >10% of PCs in BM, serum MC >30g/L, >95% aberrant PCs by immunophenotyping, or abnormal free-light chains. Standard of care of SMM is no treatment until progression disease. In this phase III trial, SMM patients at high-risk of progression were randomized to receive Len-dex as induction followed by Len alone as maintenance vs no treatment in order to evaluate whether the early treatment prolongs the time to progression (TTP) to symptomatic disease. The high-risk population was defined by the presence of both >PC 10% and MC >30g/L or if only one criterion was present, patients must have a proportion of aberrant PCs within the total PCsBM compartment by immunophenotyping of 95% plus immunoparesis. Len-dex arm received an induction treatment consisting on nine four-weeks cycles of lenalidomide at dose of 25 mg daily on days 1-21 plus dexamethasone at dose of 20 mg daily on days 1-4 and 12-15 (total dose: 160mg), followed by maintenance until progression disease with Lenalidomide at dose of 10 mg on days 1-21 every two months (amended in May 2010 into monthly). The 124 planned patients were already recruited, and 118 were evaluable (six patients didn ’t meet inclusion criteria). According to baseline characteristics, both groups were well balanced. On an ITT analysis (n=57), based on IMWG criteria, the overall response rate during induction therapy was 81%, including 56% PR, 11% VGPR, 7% CR and 7% sCR. 51 patients have completed the nine induction cycles, and the ORR was 87%, including 12% VGPR, 8% CR and 8% sCR. After a median of 7 cycles of maintenance therapy (1-21), the sCR increased to 12%. After a median follow-up of 22 months (range: 5-42), six patients progressed to symptomatic disease in the Len-dex arm: four of them during maintenance therapy and the other two progressed 3 and 8 months after early discontinuation of the trial due to personal reasons. In addition, twelve patients have developed biological progression during maintenance, and dex was added according to the protocol. In nine of them, the addition of dex was able to control again the disease without CRAB symptoms (median of 11 months). In the therapeutic abstention arm, 28 out of 61 patients (46%) progressed to active MM. The estimated hazard ratio was 6·2 (95%CI= 2·6-15), corresponding to a median TTP from inclusion of 25 months for the not treatment arm vs median not reached in the treatment arm (p<0.0001). It should be noted that 13 out of these 28 patients developed bone lesions as a symptom of active MM. Deaths in the Len-dex and no treatment arms were 1 and 2, respectively (p=0·6). Estimated 3-years overall survival (OS) from the inclusion in the trial was 98% for Len-dex arm and 82% for no treatment arm (p=0·05) and this difference was more evident if we evaluate the OS from the moment of diagnosis (HR: 6.7; 95% IC (0.7–57); p=0.03). As far as toxicity is concerned, during induction therapy, no G4 adverse events (AEs) were reported with Len-dex; 1 pt developed G3 anemia, 4 patients G3 asthenia 2 patients G3 diarrhea and 1 patient G3 skin rash; 3 patients developed G2 DVT. During maintenance, no G4 AEs were reported and only 1 patient developed G3 infection. Two patients in the Len-dex arm developed second primary malignancies (SPM): one developed polycythemia vera JAK2+, but the analysis of a frozen DNA sample obtained at the moment of inclusion in the trial demonstrated that JAK2 was already positive. The second-one was a prostate cancer in a patient with previous history of prostate enlargement plus elevated prostate specific antigen (PSA) who was closely followed by the urologist. In conclusion, this analysis shows that in high-risk SMM patients, delayed treatment resulted in early progression to symptomatic disease (median 25 months), while Len-dex as induction followed by Len as maintenance significantly prolonged the TTP (HR: 6·2), with a trend to improve the overall survival; in addition, tolerability is acceptable and concerning SPM, no safety warnings are at the present time.

Two main treatment paths in Multiple Myeloma: Non-Transplant or Transplant Transplant ineligible generally receive systemic therapy which can contains melphalan +/- one of the newer agents to treat MM Transplant eligible patients receive induction therapy, stem cell transplant (usually autologous), maintenance therapy Unfortunately MM is not curable. Eventually nearly all patients relapse and become refractory to further treatment.
The optimal administration and schedule of novel agents used in the treatment of MM is unknown. However, based on previous clinical trials there are several recommended schedules and regiments for transplant and non=transplant candidates. Bortezomib is generally administered for 8 cycles and lenalidomide is ongoing outside of transplant. There are many regimens and too many to list the appropriate dose and schedule, but here are a few of the most common and FDA approved regimens you will see given to patients with newly diagnosed MM> Bortezomib containing regimens are commonly given to transplant – eligible patients and do not impair stem cell harvest. Dexamethasone dosing varies per trial but is generally given day of and after bortezomib. Lenalidomide (Rajkumar et al, 2007) is not FDA approved for newly diagnosed MM but is included in the NCCN guidelines based on the preponderance of phase III trial data to support its safety and efficacy in this population. Thalidomide is not often given by itself but more commonly in combination with bortezomib or PLD. Nontransplant candidates are often administered any of the above treatments yet each regimen can contain melphalan. Prednisone is better tolerated in the elderly population and is preferred steroid over dexamethasone (ludwig et al, 2008) MP+ Thalidomide, MP+ Revlimid and MP+ Velcade are all reasonable options but MPV is the only fda approved combination for Newly dx MM in elderly patients. Here is the dosing schema. Maintenance is controversal but lenaliomide and bortezomib are all commonly used these days (to be discussed later today)
How does bone disease in patients with multiple myeloma occur? Malignant cells produce osteoclast-activating factors that destroy bone cells which leads to osteolysis, bone pain, and increased risk of pathologic fracture. Osteoclastic (bone destruction) and osteoblastic (bone rebuilding) activity is essential to healthy bone turnover. This process is uncoupled in myeloma as the degree of bone destruction and osteoblastic stimulation far outweighs osteoblastic activity. In fact, osteoblastic activity is nearly absent in myeloma. Bisphosphonates such as pamidronate and zoledronic acid are potent inhibitors of bone resorption. Acute phase reactions – flulike symptoms, tylenol before and the evening of infusion may diminish Renal dysfunction – monitor for albuminuria which suggests renal tubular damage over time, dose reduction and longer infusion time Osteonecrosis of the jaw Current ASCO 2007 guidelines recommend bisphosphonate treatment for up to 2 years with bisphosphonates but recent data from ASH suggests that there is an anti-myeloma benefit from BPs such as zoledronic acid.
Predisposition to infection is the single most dangerous complication of myeloma Although the exact mechanism for the increased risk of infection is not fully understood, the presence of active myeloma in the bone marrow causes an impairment of normal immune functions including a decreased response to antigen stimulation and a decrease in antibody production Infection risk is further increased by therapies used to treat myeloma, such as cytotoxic drugs, autologous or allogeneic stem cell transplantation, and glucocorticoids Patients with myeloma should be instructed to report symptoms of infection immediately In the case of life-threatening infection, IV immunoglobulin may be required Prophylactic treatment with low-dose acyclovir can reduce herpes simplex virus (HSV) and treatment with trimethoprim-sulfamethoxazole (TMP-SMX) is used to prevent Pneumocystis carinii Myeloma patients have a poor antibody response to pneumococcal and influenza vaccines References: Barlogie B, Shaughnessy J, Epstein J, et al.

Peripheral neuropathy, even mild, can be particularly devastating to the individual. This is a challenging event which can impair ones ’ QOL. Drugs such as thalidomide and bortezomib place patients at risk and up to 80% will develop even mild PN symptoms if previously treated. Vincristine and cisplatin are less commonly used but can cause PN as well Small fiber nerve endings can be damaged from the disease or treatment and produce a variety of sensations that range from mild , moderate to severe. Small fibers are most responsible for sensory changes and sensory, small –fiber neuropathy is the most common side effect of treatment. Muscle weakness and motor neuropathy can lead to paralysis if severe, and although uncommon should be monitored for in all patients receiving bortezomib and thalidomide.

Patients with MM are at risk for VTE. All patients should be risk –stratified. Considerations are included on this slide
Consider for all MM patients What is the risk of VTE? (IMWG guidelines) Increased if prior VTE, receiving lenalidomide, thalidoimide, combination chemotherapy. Also increased if BMi >30, surgery, hospitalization, sedentary Bone health: Do they require bisphosphonates if widespread osteopenia or bone lesions, most recommend aredia or zometa monthly for at least 12-24 mos after baseline dental exam ID: Is your patient at high risk for infection (myelosuppression from disease, treatment) Weekly CBCdiff for 8 weeks with lenalidomide Acyclovir prophylaxis with bortezomib IVIG for recurrent infections and hypogammaglobulinemia Prophyllactic antibiotics for prolonged neutropenia is generally not recommended by infectious disease society of america (IDSA) GI: Anti-emetic prior to bortezomib, doxorubicin Assess for diarrhea, constipation (more common to have diarrhea with bortezomib, long – term lenalidomide; constipation with doxil and especially with opioids) PN: Review increased risk of PN with bortezomib and thalidomide Prompt intervention of holding the bortezomib/thalidomide and decreasing the dose can prevent irreversible PN symptoms. SubQ bortezomib and weekly dosing can prevent incidence of painful grade 3 PN symptoms Monthly monitoring of disease parameters SPEP, UPEP, 24-hr urine, serum free light chains should be performed monthly and at least every 3 mos after remission has been obtained
final analysis of the pivotal phase 3 VISTA (Velcade as Initial Standard Therapy in Multiple Myeloma) trial, which evaluated a bortezomib-based regimen in treatment-naïve patients with multiple myeloma, upheld the survival benefit seen with bortezomib in previous analyses VISTA included 655 patients with previously untreated multiple myeloma randomized to nine 6-week cycles of MP plus bortezomib (VMP) or to MP alone. Patients were followed up at least every 12 weeks for survival and subsequent therapy use. final analysis was performed at a median follow-up of 60.1 months, which included 95% of the initial patient cohort. At 5 years, mortality risk was reduced by 31% with the VMP (median OS of 56.4 months) and 43.1 months with MP (P = .004). The median time to next treatment was 27.0 months with VMP vs 19.2 with MP (P <.001), treatment-free interval was 16.6 months versus 8.3 months (P <.001), respectively. The benefit of adding bortezomib to the treatment regimen was seen across virtually all subsets of patients, including the elderly, those with stage III disease, and those with creatinine clearance <60 mL/min. However, the small subgroup of patients with documented high-risk cytogenetics did not obtain additional benefit from bortezomib. For this group of 46 patients, median OS was 44.1 months with VMP and 50.6 months with MP. Bortezomib was not associated with an increased incidence of secondary primary malignancies above the rate seen in the general, healthy population. Hematologic malignancies were observed in 1% of patients in each arm; solid tumors were seen in 5% of the VMP arm and 3% of the MP arm.
Similar to bortezomib, oral lenalidomide remains a common treatment for patients with newly diagnosed MM (transplant eligible or ineligible) Lenalidomide works through two key mechanisms: Tumoricidal (kills tumor, makes bone marrow environment less favorable) and immmunomodulatory (increased NK activity, cytokine) Non-transplant: MPR-R vs. MPR vs. MP: Continuous MPR-R reduced risk of progression, maintenance improved PFS 31 mos “ Conclusions : Continuous Len treatment with MPR-R significantly reduced disease progression risk compared with MP and MPR in pts aged 65-75 yrs. MPR induction significantly extended PFS vs MP. To date, MPR-R has provided one of the longest median PFS (31 mos) among other available regimens (bortezomib, melphalan, prednisone: 24-27 mos; melphalan, prednisone, thalidomide: 28 mos; bortezomib, melphalan, prednisone, thalidomide: 37 mos).” Lenalidomide post-transplant maintenance improves PFS (compared to placebo)
According to IMWG: these are some criteria and brief definition of relapse Increase of > 25% from lowest response value in any one or more of the following: Serum M-component and/or (the absolute increase must be > 0.5 g/dL) 6 Urine M-component and/or (the absolute increase must be > 200 mg/24 h) Only in patients without measurable serum and urine M-protein levels; the difference between involved and uninvolved FLC levels. The absolute increase must be > 10 mg/dL Bone marrow plasma cell percentage; the absolute percentage must be > 10% 7 Definite development of new bone lesions or soft tissue plasmacytomas or definite increase in the size of existing bone lesions or soft tissue plasmacytomas Development of hypercalcaemia (corrected serum calcium > 11.5 mg/dL or 2.65 mmol/L) that can be attributed solely to the plasma cell proliferative disorder References: Durie BGM, et al.

He has received three bortezomib doses so far and tolerates well. He still has severe back pain and has trouble walking around due to it. He states he has spent most time in bed since February due to pain. He has not noted weakness or loss of sensation, also denies incontinence for urine or stool. He does not like the feeling he gets when he takes percocet which makes him &quot;goofy&quot; but he has benefited from oxycontin which was recently increased to 20mg twice a day. He tends to have constipation and controls it with MOM and enemas currently. The constipation was worse with the hypercalcemia than now with opiates. He denies nausea and vomiting, any bleeding, dyspnea, PNP symptoms, skin symptoms, or infections. He does have pain in the right rib cage, though, also constant as the back pain. He has had depression in the past but currently feels OK.
Older patients randomized between MP and CTDa, younger patients between CTD and C-VAD Thal vs. observation for maintenance: Thalidomide 50 mg/day increasing to 100 mg/day after 4 weeks if well tolerated
We thus designed the IFM 200502 protocol. 614 patients from 78 centers were enrolled between 7/2006 and 8/2008 Patients under the age of 65, with a non progressive disease after a tranplant, performed within the last 6 months, were randomized to receive a consolidation treatment with revlimid 25 mg/d , 21 days per month for 2 months followed by maintenance treatment with Placebo untill relapse (arm A) or the same consolidation followed by maintenance with low dose revlimid 10-15 mg/ until relapse (arm B) Randomization was stratified according to beta 2, del 13, and response at time of randomisation (VGPR or not)
