- Registration Number
- NCT04445701
- Lead Sponsor
- Arch Oncology
- Brief Summary
Open-label, dose escalation study to evaluate the safety, tolerability, pharmacokinetics (PK)/pharmacodynamics and initial efficacy of AO-176 as monotherapy and in combination with dexamethasone and bortezomib in adults with relapsed/refractory multiple myeloma (MM).
- Detailed Description
An open-label, multicenter, dose escalation study to evaluate the safety, tolerability and PK/pharmacodynamics of AO-176 in adults with relapsed/refractory multiple myeloma whose disease has progressed following at least 3 prior systemic lines of treatment and must have progressed on the final line of therapy received before being considered for this study.
The study will be conducted in 2 phases; Phase 1 is an ascending-dose study of AO-176 monotherapy utilizing the classic 3+3 design, with enrollment of 3 patients per cohort and expansion of the cohort in the event of a dose-limiting toxicity (DLT). Following the dose escalation portion and determination of the monotherapy recommended phase 2 dose (RP2D), an ascending dose escalation study of AO-176 and dexamethasone combined with bortezomib will be evaluated utilizing the same 3+3 dose escalation design.
Phase 2 will evaluate the clinical activity of AO-176 plus dexamethasone and bortezomib at the RP2D as determined in Phase 1 Part 2.

Group Intervention Description AO-176 + DEX Expansion Cohort AO-176 + Dex Once the monotherapy RP2D has been established, an expansion cohort of AO-176 + dexamethasone will be enrolled. AO-176 + DEX + BORT Dose Escalation AO-176 + Dex + Bort Following evaluation of AO-176 + dexamethasone, dose escalation cohorts of AO-176 + dexamethasone + bortezomib will be enrolled. Each dose escalation cohort will initially recruit 3 patients in a standard 3+3 design; cohorts will be expanded in the event of a DLT. The Phase 2 portion of the study will further evaluate the RP2D of AO-176 + DEX + BORT. AO-176 Dose Escalation Monotherapy AO-176 The dose escalation monotherapy cohorts will initially recruit 3 patients to receive AO-176 in a standard 3+3 design; cohorts will be expanded in the event of a DLT.
