Some good medical reasons to prevent adverse events
• many anti-myeloma drugs are given in combination
• many anti-myeloma treatment regimens are given for prolonged periods (months or years)
• success of treatment is related to drug dosing and treatment duration
• adverse events can:▪ negatively impact the survival of patients▪ negatively interfere with the success of the current
and future treatment▪ negatively impact the quality of life of patients
• optimal myeloma treatment is a careful balance between efficacy and toxicity of a treatment regimen

▪ Pharmacological treatment• medication: only to alleviate symptoms
✓ anticonvulsants: gabapentin, pregabalin
✓ opioids: fentanyl, tramadol, morphine,
✓ serotonin/norepinephrine-reuptake inhibitors
▪ Topical treatment: mostly of limited use• lidocaine patch
• 0.5% menthol in calamine cream
▪ others▪ physical exercise (especially when patient is on steroids)
▪ mineralocorticoids in case of hypotension
▪ caution with high doses of Vit C or Vit B

Monitoring:
• Patients at risk should1:
• be treated with caution and remain under close follow-up
• have a comprehensive medical assessment prior to starting treatment with carfilzomib
• Assessment should optimise the patient’s status, with particular attention to blood pressure and fluid management1
Risk factors for cardiovascular complications with carfilzomib
Fluid management:• Hydration is recommended before carfilzomib administration1
• Reduction of fluid volume in patients with increased cardiac risk should be considered1,4,5
• Diuretics could be considered to optimise fluid balance5

Additional prophylactic measures
• For daratumumab: patients with a history of obstructive pulmonary disease1
▪ close observation
▪ the use of post-infusion medications including short- and long-acting bronchodilators, and inhaled corticosteroids should be considered
▪ following the first four infusions, if the patient experiences no major IRRs, these inhaled post-infusion medications may be discontinued at the discretion of the physician
• For all monoclonal antibodies: increased risk of herpes zoster and other infections▪ anti-viral prophylaxis should be considered for the prevention of herpes zoster virus

Conclusions• treatment practices in relapsed multiple myeloma are rapidly
changing
• single-agent short-term exposure has been gradually replaced by long-term multi-drug treatment regimens
• the success of treatment is largely dependent on optimal drug dose delivery and treatment duration
• the quality of life of MM patients is largely dependent on theabsence of disabling or dangerous adverse events
• more active drug combinations and advanced immunotherapies are associated with more profound immune suppression and can induce more adverse events
• awareness and prevention of adverse events are cornerstones of successful myeloma management
