Brief summary
Multiple myeloma (MM) is an incurable plasma cell cancer that almost all patients eventually relapse despite advancement in treatment strategies. B-cell maturation antigen (BCMA) is a cell surface receptor that expressed primarily by malignant and normal plasma cells. This is a single-arm that includes three arms, Selinexor(ATG-010) in Combination with Immunomodulator (Thalidomide/ Pomalidomide/ Lenalidomide)and Dexamethasone to Treat Relapsed/Refractory Multiple Myeloma Patients. To evaluate efficacy and safety of Selinexor in combination with Immunomodulator and Dexamethasone in RRMM patients received at least one prior lines of therapy.
Detailed description
This is a single-arm and open-label phase II study of Relapsed/Refractory Multiple Myeloma patients who have received at least one prior lines of treatment therapy; This study includes three experimental arms. Arm I is given XTd regimen (ATG-010 60mg/d QW, Thalidomide 100mg/d and Dexamethasone 40mg/d QW) in approximately 30 subjects. Arm II is given XRd regimen (ATG-010 60mg/d QW, Lenalidomide 25mg/d d1-21 and Dexamethasone 40mg/d QW) in approximately 30 subjects, Arm III is given XPd(ATG-010 60mg/d QW, Pomalidomide 4mg/d d1-21 and Dexamethasone 40mg/d QW ) in approximately 30 subjects,The three arms are 4 weeks per cycle and include a total of 12 cycles.
Interventions
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 60mg/d QW
100mg/d, Po. on day1-28
PO,Lenalidomide 25mg once daily from D1-21
Pomalidomide will be given at 4mg once daily for 21 days in a 28-day cycle, PO.
Dexamethasone will be given at a dose of 40mg orally once a week for 4 weeks (D1,8,15,22).

Eligibility
Inclusion criteria
* Patients must meet all of the following inclusion criteria to be eligible to enroll in this study: 1. Known and written informed consent (ICF) voluntarily. 2. Age ≥ 18 years and ≤ 75 years. 3. Patients with multiple myeloma who have received first-line treatment (induction, autologous transplantation and maintenance as the same first-line treatment) and achieved at least partial remission in induction. 4. At or after accepting first-line regimen, subjects must have progression disease (PD) recorded which is determined by researcher according to IMWG criteria. 5. Any clinically significant non-hematological toxicities (except for hair loss, peripheral neuropathy, which is otherwise stipulated in Article 13 of the
Exclusion criteria
) that relevant to previous therapies must have resolved to ≤Grade 2 prior to first dose of study drug. 6. Left ventricular ejection fraction#LVEF #≥50% by an echocardiogram or MUGA scan in 42 days before the first administration 7. Adequate hepatic function: total bilirubin \< 2× upper limit of normal (ULN) (for patients with Gilbert's syndrome, a total bilirubin of \< 3× ULN is required), AST \< 2.5× ULN, and ALT \< 2.5× ULN. 8. Adequate renal function: estimated creatinine clearance ≥ 20 mL/min (calculated using the formula of Cockroft-Gault). 9. Eastern Cooperative Oncology Group (ECOG) Performance Status of 0, 1, or 2. 10. Measurable MM as defined by at least one of the following: 1. Serum M-protein (SPEP) ≥ 10 g/L 2. 24 hours-Urinary M-protein excretion ≥ 0.2 g (200 mg) 3. Serum FLC ≥ 100 mg/L with abnormal FLC ratio 11. Expected survival is more than 6 months. 12. Adequate hematopoietic function (no blood transfusion within 2 weeks and no G-CSF/GM-CSF supportive treatment within 1 week prior to screening test): 1. Hemoglobin level ≥ 80 g/L 2. ANC ≥ 1,000/mm3 (1.0×109/L) 3. Platelet count ≥ 75,000/mm3 (75×109/L) 13. Female patients of childbearing potential must meet below two criteria: 1. must agree to use effective contraception methods since signature in ICF, throughout the study and for 3 months following the last dose of study treatment. 2. must have a negative serum pregnancy test at screening. Note: A woman is considered of childbearing potential following menarche and until becoming postmenopausal (defined as no menstrual period for a minimum of 12 months) or permanently sterile (having undergone a hysterectomy, bilateral salpingectomy or bilateral oophorectomy). A woman who is taking oral contraceptive or using intrauterine device is considered of childbearing potential. 14. Male patients (including those who have received vasectomy) must use a condom if sexually active with a female of child-bearing potential throughout the study and for 3 months following the last dose of study treatment.
