Study Design
Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment
Name: ABT-888/Bortezomib
Type: Drug
Overall Status
The combination of PARP inhibitor (ABT-888) with a proteasome inhibitors (bortezomib) have demonstrated significant anti-myeloma effects in preclinical lab and animal studies. The goal of this phase I trial is to evaluate in patients with relapsed or refractory multiple myeloma the safety, toxicity profile and tolerability of ABT-888 (Veliparib) administered on a schedule including twice daily oral dosing for 14 days followed by 1 week rest in combination with standard dosing of Bortezomib.
Detailed Description
This is a dose-finding / dose escalation phase I trial of ABT-888 (Veliparib) in combination with Bortezomib and Dexamethasone in patients with relapsed or refractory multiple myeloma. ABT-888 is given orally (PO) twice daily (every 12 hours) for 14 days in a 21 days cycle.

First dose to be given within 1 hour of Bortezomib on day 1. Planned starting dose is 20 mg PO every 12 hours. Starting dose escalation is planned until an MTD is reached.

- Pregnant or lactating women

- Patients receiving concurrent treatment with other anti-cancer therapy any other investigational agents.

- Patients with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive
