Written in Blood with significant improvement in OS at six months compared with non- responders: 26 versus 19 months (p=0.001). Hematologic progres- sion also predicted OS (median OS = 25 months for patients who progressed; p=0.013), as no deaths were reported in patients who did not progress. Thirty-one grade 3/4 adverse events (AEs) were reported in 15 patients (54%); the most common of which were fluid retention (25%), infection (25%), atrial fibrillation (7%), and deep vein thrombosis (7%). The most common grade 1/2 AEs were fever (n=15, 54%), neutropenia (n=12, 43%), skin rash (n=4, 14%), and worsening periph- eral neuropathy (n=2, 7%). Dose reductions were required in nine patients treated with pomalidomide (32%) and 10 pa- tients treated with dexamethasone (36%). Dr. Palladini and co-authors noted that “dose reductions were not associated with clinical, bio- chemical, and echographic markers of heart involvement.” Twenty-six patients eventually discontinued treatment, most commonly because of disease progression (n=14, 50%), followed by AEs (n=8, 29%), patient choice (n=3, 11%), and achievement of durable CR (n=1, 4%). Two patients remained on treatment after 28 and 30 cycles, having achieved VGPR and PR, respectively. Nineteen patients (68%) died during follow-up and the remaining patients were fol- lowed for a median of 44 months. No deaths occurred in the first 100 days following treatment.
