4:03PM Array Biopharma announces positive data for ARRY-520 and ARRY 614 at the 2012 Annual Meeting of the American Society of Hematology (ARRY) 3.62 -0.01 : Co announced positive data for ARRY-520 and ARRY-614 at the 2012 Annual Meeting of the American Society of Hematology (ASH). New results presented at the meeting for ARRY-520 in addition to those described in the abstracts published by ASH in early November included: Overall survival of 19 months and progression free survival of 3.7 months were observed in multiple myeloma patients taking ARRY-520 alone; A clinical benefit rate of 50% was observed in heavily pre-treated (median 10 prior regimens) multiple myeloma patients taking ARRY-520 plus dexamethasone who were selected for low AAG levels Initial signs of clinical activity were observed in the ongoing ARRY-520+Kyprolis; combination trial: 56% clinical benefit rate.
In a Phase 2 trial with ARRY-520 in patients with triple-refractory multiple myeloma and a median number of 10 prior treatment regimens, ARRY-520 plus low-dose dexamethasone demonstrated a 22% overall response rate with manageable safety. The most common drug-related adverse events include myelosuppression, fatigue and mucosal inflammation. This response rate is comparable to the response rates reported in pomalidomide and Kyprolis studies, which included patients with only half the number of median prior treatment regimens.
