Stage 1 of Phase 3 study completed

Stage 2 of Phase 3 study will enrol additional 190 patients

Madrid, 18th December: The Independent Data Monitoring Committee (IDMC) has notified PharmaMar, a biopharmaceutical subsidiary of Grupo Zeltia (ZEL.MC), that it recommends completion of the on-going Phase 3 trial of Aplidin® (ADMYRE) in patients with relapsed/refractory multiple myeloma. The two-stage, 2:1 randomized Phase 3 study is evaluating Aplidin® in combination with dexamethasone versus dexamethasone alone. The IDMC recommendation follows a comprehensive analysis of efficacy and safety data from the 60 patients required in the first stage of the Phase 3 trial in which the study comfortably met the established efficacy threshold.

PharmaMar will enroll an additional 190 patients in the second stage of the Phase 3 trial. The number of centers initially planned will be doubled in order to accelerate the recruitment process. The Primary endpoint of the phase 3 study is a 60% improvement in progression free survival. Enrollment of Stage 2 of this phase 3 is anticipated to begin in Q12013.
