Abstract Disclosures


Background: POM + LoDEX has shown significant clinical activity in RRMM pts including those refractory to lenalidomide and bortezomib. Renal impairment is a common comorbidity for MM pts, occurring in > 40%. POM is extensively metabolized with less than 5% renally eliminated as parent drug. Thus, renal function may not substantively affect parent drug exposure. Previous POM trials excluded pts with severe renal impairment. MM-008 is a phase 1, multicenter, open-label study designed to assess the PK and safety of POM + LoDEX in RRMM pts and normal or impaired renal function. Methods: RRMM pts (≥ 1 prior therapy [Tx]) with creatinine clearance (CrCl) ≥ 60 ml/min (cohort A) or severe renal impairment (CrCl < 30 ml/min [cohort B]) not requiring dialysis were included. Cohort A received POM 4 mg and cohort B received POM 2 mg or 4 mg D1-21/28-day cycle following a standard 3 + 3 dose-escalation design. Both cohorts received DEX 40 mg (20 mg for pts aged > 75 y) D1, 8, 15, and 22. Cohort C will assess pts with severe renal impairment (CrCl < 30 ml/min) requiring dialysis (up to 14 pts planned). Pts were not permitted to enroll in more than 1 cohort. G-CSF was not permitted in cycle 1. Tx continued until progressive disease or unacceptable toxicity. Results: As of Feb 5, 2013, 11 pts have been treated (8 pts in cohort A; 3 pts in cohort B at 2 mg). Age ranged from 46-71 y (cohort A) and 57-64 (cohort B). 5 pts were aged > 65 y in cohort A (aged 66, 69 [n = 3], and 71 y); none in cohort B. 7 pts in cohort A have received > 1 cycle of Tx; 5 pts have received ≥ 3 cycles. One pt in cohort B has received > 3 cycles. All 3 pts in cohort B have completed 1 full cycle of Tx with no dose-limiting toxicities reported. Dose escalation is planned. The most common grade 3/4 adverse events (AEs) in cohort A were neutropenia (n = 3) and pneumonia (n = 2). No grade 3/4 AEs have been observed for pts in cohort B to date. POM dose reduction due to AE occurred in 2 pts (both in cohort A), all pts remain on study. PK and updated AE data will be presented at the meeting. Conclusions: MM-008 is an ongoing trial evaluating PK and safety in pts with renal impairment. Early tolerability data are encouraging. Clinical trial information: NCT01575925.
