A Phase 1 Open-label Study Evaluating the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Efficacy of AMG 701 in Subjects With Multiple Myeloma
The purpose of this First-in-Human Phase 1 study is to determine during the escalation part if AMG 701 given as weekly short term IV infusions is safe and tolerable followed by a dose expansion part to gain further efficacy and safety experience with AMG 701 in adult subjects with relapsed / refractory multiple myeloma. The study will be conducted in multiple sites and test increasing doses of AMG 701. The safety of subjects will be monitored by intensive assessments of vital signs, electrocardiograms, physical examinations, and laboratory tests.

- Multiple myeloma meeting the following criteria:
- Pathologically-documented diagnosis of multiple myeloma that is relapsed or is refractory as defined by the following:
- Relapsed after > or = 2 lines of prior therapy that must include a proteasome inhibitor (PI), an immunomodulatory drug (IMiD), and, where approved and available, a CD38-directed cytolytic antibody in any order during the course of treatment OR refractory to PI, IMiD, and CD38- directed cytolytic antibody,
- Subjects who could not tolerate a PI, IMiDs, or a CD38-directed cytolytic antibody are eligible to enroll in the study.
