Questions à se poser:
1. Est-ce qu’il y a une indication de traitement?
2. Caractéristiques du patient?
3. Caractéristiques de la maladie?
4. Le patient est-il candidat pour une étude?
5. Le patient est-il candidat pour une autogreffe?
6. Quel est le traitement supportif adéquat?

CRAB:
• Calcium levels • serum calcium > 0.25 mmol/l above upper limit of normal or
> 2.75 mmol/l
• Renal insufficiency• creatinine > 170 mmol/l
• Anaemia• haemoglobin 2.0 g/dl below lower limit of normal or < 10 g/dl
• Bone lesions• lytic lesions or osteoporosis with compression fractures
(MRI or CT may clarify)
• Other• symptomatic hyperviscosity, amyloidosis, recurrent infections (>
2 episodes in 12 months)
CRAB (calcium, renal insufficiency, anaemia, or bone lesions)

• 86.5% of patients were double refractory to a proteasome inhibitor (PI) and immunomodulatory drug (IMiD)3
• Combined overall response rate (ORR): 31%3
• Median overall survival (OS): 20.1 months3
• 2-year OS was ~75% in responders
• Median OS was 18.5 months MR/SD patients
