About this study

Selinexor (KPT-330, Xpovio) is a first in class selective inhibitor of nuclear export which has been approved for use in relapsed and refractory multiple myeloma (RRMM). This trial will seek to evaluate the outcomes achieved with selinexor based combination in RRMM selected by physician's choice and compared prospectively to ex vivo drug sensitivity testing results. Participants will be enrolled and assigned into one of three treatment selection groups. The study sample size was powered to analyze the total group of patients enrolled. It was not powered to analyze each treatment regimen individually.

Selection groups are as follows:

Group 1: Selinexor + pomalidomide + dexamethasone (SPd) Group 2: Selinexor + daratumumab + dexamethasone (SDd) Group 3: Selinexor + carfilzomib + dexamethasone (SKd)

Read the detailed description

This study is a single institution, open-label phase II study to evaluate the overall response rate achieved with selinexor and dexamethasone based three drug combination therapy, selected by physician's choice, in patients with relapsed/refractory multiple myeloma.

Patients with RRMM will be eligible for enrollment. During screening, in addition to standard of care disease assessments, participant's bone marrow aspirate will be evaluated using a novel ex vivo Myeloma Drug Sensitivity Testing platform (My-DST). The following agents will be eligible for physician's choice, and in parallel evaluated for sample sensitivity in MyDST: pomalidomide, carfilzomib and daratumumab. Agents will be tested individually, in combination with selinexor and in combination with selinexor and dexamethasone. Results from MyDST will be not be available to investigators at time of treatment assignment, but will be evaluated to better characterize test performance and relationship with treatment outcomes.

Investigators will assign patients to one of the following treatment combinations: Selinexor/Pomalidomide/Dexamethsone (SPd), Selinexor/Daratumumab/Dexamethasone (SDd) or Selinexor/Carfilzomib/Dexamethasone (SKd). Investigators will use patient specific considerations such as prior therapeutic exposures, response to / tolerance of prior therapies and comorbid conditions which may increase risk for toxicity with specific agents to guide expert judgement in selecting partner agent for selinexor and dexamethasone. Treatment will continue until progression of disease, unacceptable toxicity or death.

This study will evaluate if physician's choice partner drug selection for selinexor based combination therapy in RRMM will lead to an overall response rate of 75% or higher.

  3. Overall Survival

    To evaluate the overall survival achieved with physician's choice selinexor-based combination therapy after 2 years off of study treatment.

    Measured: From study start date to study end date or death (whichever comes first), assessed up to 2 years

  4. Duration of Response

    To evaluate the duration of response achieved with physician's choice selinexor-based combination therapy

    Measured: End of Treatment +2 years, or date of progression (whichever comes first), assessed up to 2 years

  5. Time to Next Treatment

    To evaluate the time to next treatment achieved with physician's choice selinexor-based combination therapy

    Measured: End of Treatment +2 years, or date of progression (whichever comes first), assessed up to 2 years

  6. Safety and Tolerability of Selinexor in Combination With Partner Backbone Agents

    Occurrence, nature, and severity of adverse events

    Measured: From first dose of study drug through 30 days after last dose of protocol required therapies

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Selinexor, Pomalidomide and Daratumumab in people with Multiple Myeloma in Relapse, run by University of Colorado, Denver at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 15 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 2 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 6 Mar 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall Response Rate (time frame: Overall response rate was assessed from C1D1 through 30 days post last dose (approximately 10 months).). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Oct 2026.
