First clinical (phase 1b/2a) study of iberdomide (CC-220; IBER), a CELMoD, in combination with dexamethasone (DEX) in patients (pts) with relapsed/refractory multiple myeloma (RRMM).

Conclusions: IBER + DEX showed favorable efficacy and safety in heavily pretreated pts with RRMM who failed multiple prior therapies. This study is ongoing, including combinations of IBER with DARA or BORT. Clinical trial information: NCT02773030

Efficacy of carfilzomib lenalidomide dexamethasone (KRd) with or without transplantation in newly diagnosed myeloma according to risk status: Results from the FORTE trial. 

Conclusions: KRd-ASCT-KRd and KRd12 were equally effective in inducing high-quality responses, with about 50% of high-risk pts achieving MRD negativity. In high-risk pts ASCT reduced the risk of early relapse. Clinical trial information: NCT02203643

E3A06: Randomized phase III trial of lenalidomide versus observation alone in patients with asymptomatic high-risk smoldering multiple myeloma.

Conclusions: Overall, this trial represents the largest randomized trial in SMM to date. In conjunction with the Spanish data, this trial may support a change in clinical practice. Clinical trial information: NCT01169337

A phase III randomized, open label, multicenter study comparing isatuximab, pomalidomide, and low-dose dexamethasone versus pomalidomide and low-dose dexamethasone in patients with relapsed/refractory multiple myeloma (RRMM).

Conclusions: IsaPd significantly improved PFS and ORR vs Pd, with a manageable safety profile. IsaPd is an important new treatment option for the management of RRMM. Clinical trial information: NCT02990338

Conclusions: D-Rd pts received less R vs Rd group regardless of age. Efficacy of D-Rd in <75 and ≥75 y pts was consistent with the ITT population, and D-Rd demonstrated acceptable tolerability regardless of age. Together with the phase 3 ALCYONE study, these studies confirm clinical benefit of daratumumab plus standard-of-care in transplant-ineligible NDMM pts ≥75 y of age. Clinical trial information: NCT02252172

Efficacy and safety of daratumumab, lenalidomide, and dexamethasone (D-Rd) in relapsed or refractory multiple myeloma (RRMM): Updated subgroup analysis of POLLUX based on cytogenetic risk. 

Conclusions: D-Rd demonstrates significant efficacy in high-risk RRMM. Among high-risk pts, MRD negativity was only achieved with D-Rd. Clinical trial information: NCT02076009

Fedratinib (FEDR) in myelofibrosis (MF) patients previously treated with ruxolitinib (RUX): A reanalysis of the JAKARTA-2 study.

Conclusions: FEDR provided clinically meaningful reductions in splenomegaly and symptom burden in pts with MF who met more stringent criteria for R/R or intolerance to RUX. Clinical trial information: NCT01523171

RUX failure.

  Prior Analysis Current Analysis
Resistance RUX Tx ≥ 14 d with no response or stable disease per investigator, disease progression, or loss of response Relapsed: RUX Tx ≥ 3 mo with regrowth, defined as < 10% SVR or < 30% decrease in spleen size from BL, following an initial response
Refractory: RUX Tx ≥ 3 mo with < 10% SVR or < 30% decrease in spleen size from BL
Intolerance RUX Tx ≥ 14 d before discontinuing Tx due to unacceptable toxicity RUX Tx ≥ 28 d complicated by development of RBC transfusion requirement (≥ 2 units/mo for 2 mo); or grade ≥ 3 thrombocytopenia, anemia, hematoma/hemorrhage while on RUX
