Summary
Brief summary (as posted)
This clinical study is being conducted at multiple sites to determine the activity, safety, and tolerability of XL999 when given weekly to patients with relapsed or refractory multiple myeloma. XL999 is a small molecule inhibitor of cellular factors including VEGFR, PDGFR, and FGFR that may be involved in multiple myeloma.
