Please assess the completion status of the following clinical trial:

Trial Title: Selinexor Treatment of Refractory Myeloma

Study Design Characteristics:
- Allocation: NON_RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: PHASE2
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~Measurable MM based on modified IMWG guidelines. Defined by at least one of the following:~1. Serum M-protein ≥ 0.5 g/dL by serum electrophoresis (SPEP) or for IgA myeloma, by quantitative IgA~2. Urinary M-protein excretion ≥ 200 mg/24 hours~3. Free Light Chain (FLC) ≥ 100 mg/L, provided that the FLC ratio is abnormal~4. If serum protein electrophoresis is felt to be unreliable for routine M-protein measurement, then quantitative Ig levels by nephelometry or turbidimetry are acceptable~   * Must have previously received ≥ 3 anti-MM regimens including: an alkylating agent, lenalidomide, pomalidomide, bortezomib, carfilzomib, daratumumab, and a glucocorticoid. There is no upper limit on the number of prior therapies provided that all other inclusion/exclusion criteria are met.~  * MM refractory to previous treatment with one or more glucocorticoids, parenteral PI (i.e., bortezomib and/or carfilzomib), IMiD (i.e., lenalidomide and/or pomalidomide), and the anti-CD38 mAb, daratumumab. Refractory is defined as ≤ 25% response to therapy, or progression during therapy or progression within 60 days after completion of therapy.~Exclusion Criteria:~* Active smoldering MM.~* Active plasma cell leukemia.~* Documented systemic amyloid light chain amyloidosis.~* Active CNS MM.

Study Arms:
- Part 1 (Type: EXPERIMENTAL): Participants with quad-exposed, double-class-refractory (i.e. previously treated with lenalidomide, pomalidomide, bortezomib, carfilzomib, but not an anti-CD38 mab) and penta-exposed, triple-class-refractory multiple myeloma (MM) (i.e. previously treated with lenalidomide, pomalidomide, bortezomib, carfilzomib, and daratumumab, and refractory to prior treatment with glucocorticoids, an immunomodulatory agent (IMiD), a proteasome inhibitor (PI), and the anti-CD38 mAb daratumumab) received, two dosing schedules (1) Selinexor 80 milligrams (mg) plus low-dose dexamethasone 20 mg (Sd) twice-weekly on Days 1 and 3 for 3 weeks of each 4-week cycle (2) Selinexor 80 mg plus low-dose dexamethasone 20 mg (Sd) twice-weekly continuously in 4-week cycles; until disease progression, death, or unacceptable toxicity (maximum duration of approximately 13 months).
- Part 2 (Type: EXPERIMENTAL): Participants who previously had received more than 3 anti-MM regimens and had penta-exposed, triple class-refractory MM (i.e. previously treated with lenalidomide, pomalidomide, bortezomib, carfilzomib, and daratumumab, and refractory to prior treatment with glucocorticoids, an IMiD, a PI, and the anti-CD38 mAb daratumumab) received, Selinexor 80 mg post oral (PO) plus low-dose dexamethasone 20 mg Sd twice-weekly on Days 1 and 3 until disease progression, death, or unacceptable toxicity (maximum duration of approximately 17 months).

Based on this trial design, predict the completion outcome and termination type (if applicable).
