Health-related quality of life (HRQoL) in the phase III QUAZAR-AML-001 trial of CC-486 as maintenance therapy for patients with acute myeloid leukemia (AML) in first remission following induction chemotherapy (IC)
Abstract No : 7533
Abstract Type : Poster Discussion Session
Indication : Acute Myeloid Leukemia
Intervention : CC-486
Company : BMS.
Technology : Small molecule
Results:
In all, 225/238 pts (95%) in the CC-486 arm were evaluable for FACIT-Fatigue and EQ-5D-3L, and 219/234 pts (94%) in the PBO arm were evaluable for FACIT-Fatigue and 217 (93%) for EQ-5D-3L. Pt characteristics were comparable between Tx arms. Most pts (61%) were 65-74 yrs of age. Median number of CC-486 Tx cycles was 12 and PBO cycles was 7. Compliance rates were > 95% at BL and remained high (> 85%) at all post-BL visits except for EOT. At BL, pts in both Tx arms had comparable low levels of fatigue and generally good HRQoL relative to an age-matched general population. There were no meaningful differences between CC-486 and PBO in mean changes from BL in FACIT-Fatigue or EQ-5D-3L scores at any post-BL visit. There was no statistically significant difference between Tx arms in proportion of pts with a clinically meaningful deterioration in FACIT-Fatigue score at any post-BL visit except at cycle 29 (likely due to chance; no adjustment made for multiple testing), or in EQ-5D-3L at any visit. Median time to deterioration was not significantly different between CC-486 and PBO on the FACIT-Fatigue scale (41 vs 44 weeks, respectively; P = 0.70) or the EQ-5D-3L (200 vs 164 weeks; P = 0.63).
Conclusion:
HRQoL and low levels of fatigue were preserved with CC-486 maintenance Tx. CC-486 significantly improved OS and RFS while maintaining HRQoL comparable to PBO.
Commentary:
CC-486 highlights maintaining HRQoL similar to placebo along with survival and RFS benefit.
