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since the initiation of the study drug, or the last patient has expired, has been lost to follow-up, or has withdrawn consent, whichever occurs first.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since the initiation of the study drug, or the last patient has expired, has been lost to follow-up, or has withdrawn consent, whichever occurs first.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 Groups

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.

Group Type: EXPERIMENTAL

Selinexor

Intervention Type: DRUG

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

Bortezomib

Intervention Type: DRUG

The investigators gave patients subcutaneous bortezomib 1.3mg/sqm on days 1, 8,15 of a 21- day cycle.

standard bortezomib-lenalidomide-dexamethasone

Lenalidomide

Intervention Type: DRUG

The investigators gave patients oral lenalidomide 25mg on days 1 to 14 of a 21-day cycle.

standard bortezomib-lenalidomide-dexamethasone

Dexamethasone

Intervention Type: DRUG

The investigators gave patients oral dexamethasone 40mg on days 1, 8, 15 of a 21-day cycle.
