Selinexor Plus VRd in High Risk Newly Diagnosed Multiple Myeloma
Study Details
Study Description
Brief Summary
This is a single-arm and open-label study to explore XVRd (ATG-010, Bortezomib, Lenalidomide and Dexamethasone) regimen in high-risk newly diagnosed multiple myeloma.The primary objective of the dose escalation study is to determine the safety, tolerability, and recommended phase II dose (RP2D) of selinexor; Then dose expansion at the RP2D level based on dose escalation phase will be conducted to evaluate the efficacy, safety and tolerability.The enrollment period for this study is expected to be approximately 12 months.
The study will end when all patients have completed 12 cycles treatment/follow-up since the initiation of the study drug, or the last patient has expired, has been lost to follow-up, or has withdrawn consent, whichever occurs first.

Detailed Description
This is a single-arm and open-label study to explore XVRd (ATG-010, Bortezomib, Lenalidomide and Dexamethasone) regimen in high-risk newly diagnosed multiple myeloma. Approximately 3-42 patients will be enrolled in the study. In dose escalation phase, patients with high-risk NDMM will be treated with VRd standard regimen (bortezomib 1.3mg/m2 SC on day1,4,8,11, lenalidomide 25 mg on day 1-14 and dexamethasone 40mg on day 1,8,15 in a 21-day cycle) plus escalating doses of selinexor 40 mg or 60 mg on days 1, 8, and 15 of each cycle in a 3+3 design. The primary objective of the dose escalation study is to determine the safety, tolerability,and recommended phase II dose (RP2D) of selinexor; Then dose expansion at the RP2D level based on dose escalation phase will be conducted to evaluate the efficacy, safety and tolerability. All of the patients will receive 12 cycles of XVRd , and subjects can choose maintenance treatment with XR after 12 cycles of XVRd.The primary objective of the dose escalation study is to determine the safety, tolerability, and recommended phase II dose (RP2D) of selinexor; Then dose expansion at the RP2D level based on dose escalation phase will be conducted to evaluate the efficacy, safety and tolerability.
The enrollment period for this study is expected to be approximately 12 months. The study will end when all patients have completed 12 cycles treatment/follow-up since the initiation of the study drug, or the last patient has expired, has been lost to follow-up, or has withdrawn consent, whichever occurs first.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Selinexor-VRd（XVRd） bortezomib SC 1.3mg/sqm on day 1,4,8,11, lenalidomide oral 25 mg on day 1-14, and dexamethasone 40mg on day 1,8,15 in a 21-day cycle; Selinexor dose escalation: 40，60mg respectively on day 1,8,15 for 21-days cycles. Then Selinexor will be given at the recommended dose level on phase II. |
Drug: Selinexor
Selinexor (ATG-010# is a first-in-class, oral selective exportin 1 (XPO1) inhibitor (1,2). Selinexor functions by binding with and inhibiting the nuclear export protein XPO1 (also called CRM1), leading to the accumulation of tumor suppressor proteins in the cell nucleus along with inhibition of translation of oncoprotein mRNAs.
Selinexor dose escalation: 40, 60mg respectively on day 1,8,15 for 21 days cycles
Other Names:
Drug: Bortezomib
The investigators gave patients subcutaneous bortezomib 1.3mg/sqm on days 1, 8,15 of a 21- day cycle.

Outcome Measures
Primary Outcome Measures
- Dose Escalation: Maximum Tolerated Dose (MTD) [Assessed from the date of first dose of study treatment to the first cycle ends (maximum 21days) ;]
The MTD will be determined by study definition as the highest dose level without significant safety and tolerability concern.
- Dose Escalation: Recommended Phase 2 Does (RP2D) [Assessed from the date of first dose of study treatment to the first cycle ends (maximum 21days) ;]
The RP2D is defined as the dose level chosen by the sponsor (in consultation with the investigators) for the dose expansion arms, based on safety, tolerability, efficacy, PK, and PD data collected during the dose escalation portion of the study.
- Dose Expansion: MRD negative remission [At any time up to 12 months after XVRD treatment]
MRD negative remission (<10-5) as defined by IMWG consensus
Secondary Outcome Measures
- complete response (CR) [Cycle 1 Day 1 (each cycle consists of maximum 21 days) until a VGPR, CR or PR (up to 12 cycles)]
complete response (CR) and stringent complete response (sCR)
- Overall Survival (OS) [12 months]
Occurrence of death regardless of cause
- Progression-Free Survival (PFS) [12 months]
Duration from start of study treatment to PD or death (regardless of cause), whichever comes first
- Duration of Response (DOR) [12 months]
Duration from the first observation of at least PR to time of disease progression, or deaths due to disease progression, whichever occurs first
- Clinical Benefit Rate (CBR) [12 months]
Clinical Benefit Rate (CBR=ORR+Minor Response [MR])
- Disease Control Rate (DCR) [12 months]
Disease Control Rate (DCR=CBR+Stable Disease[SD; for a minimum of 12 weeks])
- Number of Participants with Adverse Events [From first dose of study drug administration to end of treatment (up to 12 months)]
Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Treatment-Emergent Serious Adverse Events (TESAEs)
