Phase II Study of Infusional Carfilzomib in Patients with Relapsed or Refractory MM • CFZ dose of 20/56 mg/m2 administered as a 30-minute IV infusion resulted in high response rates in our BTZ treated/refractory population. • Response rates were comparable to those seen in PX171-0071 • CFZ dose of 20/56 mg/m2 was associated with more frequent cardiac and pulmonary toxicities, particularly HTN and pulmonary edema/CHF. – Possible contribution from “supportive” measures? • CFZ dose of 20/56 mg/m2 continues to be explored in Lendvai et al, ASH 2012 Abstr 947 ongoing Phase II/III studies.

ASH 2012 abstract 450. Pomalidomide Plus Low-Dose Dexamethasone (Pom/Dex) in Relapsed Myeloma (345 patients) • Pom/Dex has high response rates even in heavily pretreated relapsed myeloma • Pom/Dex is well tolerated • Toxicity and efficacy are similar between the 2mg and 4mg dose levels • The strongest predictors of response include the number and type of prior regimens. • The strongest predictors of TTP and survival include the number and type of prior regimens, LDH, and B2M.
