E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Escalation phase (Phase I): 1. To determine the maximum-tolerated dose (MTD) and to characterize dose limiting toxicity (DLT) of escalating doses of BHQ880 (up to a maximum dose of 20 mg/kg) in combination with standard anti-myeloma therapy and zoledronic acid. Expansion phase (Phase II): 1. To determine one or more doses of BHQ880 for further development based on dose-efficacy modeling, where efficacy is relative to placebo in terms of time to first SRE from randomization and change in bone markers for bone resorption and formation in combination with zoledronic acid plus standard anti-myeloma therapy. |

E.2.2 | Secondary objectives of the trial |
Secondary objectives (Phase I and Phase II)in relapsed or refractory multiple myeloma patients in combination with zoledronic acid plus standard anti-myeloma therapy, to: 1. characterize acute and chronic safety and tolerability of various doses of BHQ880, 2. characterize single-dose and repeated-dose pharmacokinetic profiles of intravenously administrated BHQ880, 6. determine the pharmacodynamic effects of BHQ880 by measuring biochemical markers of bone formation, resorption and metabolism 7. assess the effect of BHQ880 on the Ca2+ and P+ metabolism, 8. monitor preliminary evidence of anti-tumor activity of BHQ880, 9. investigate the effect of BHQ880 in combination on the radiographic size and number of lytic bone lesions as measured by bone survey; and: 3. To assess the potential immunogenicity of intravenously infused BHQ880 4. To characterize the binding kinetics of DKK1/BHQ880 complex in serum 5. To characterize changes in serum DKK1 levels during treatment. |
