What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Overall Response Rate (ORR) Assessed as Per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1

    ORR was defined as the percentage of participants who achieved complete response (CR) or partial response (PR). ORR was assessed by RECIST 1.1 as defined by the Investigator based on radiologic criteria. Per RECIST 1.1 criteria, CR was defined as disappearance of all target lesions, any pathological lymph nodes (whether target or non-target) with reduction in short axis to less than (<)10 millimeter (mm). PR was defined as at least a 30 percentage (%) decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

    Measured: From the date of randomization until the documentation of CR or PR, whichever occurs first (up to 24 months)

Secondary outcomes (10)
  1. Progression-free Survival (PFS) as Per RECIST v 1.1

    PFS was defined as time from date of first treatment to the date of first confirmed progressive disease (PD), assessed by RECIST 1.1 is objectively documented or death due to any cause. As per RECIST 1.1 criteria, PD was defined as at least a 20% increase in the sum of the longest diameter (SLD), taking as reference the smallest SLD recorded from baseline or the appearance of 1 or more new lesions.

    Measured: From the date of randomization until disease progression or death, due to any cause (up to 24 months)

  2. Overall Survival (OS)

    OS was defined as the time from date of first study treatment until death due to any cause. If death event did not occur during the follow-up period, the participant was censored at the date of discontinuation from the study (i.e. withdrawal of consent), or date of last participating visit (e.g., a telephone contact with participant status being alive) on or before database cutoff date, whichever occurs first.

    Measured: From the date of first study treatment up to death (up to 24 months)

  3. Complete Response Rate (CRR)

    Complete response rate was defined as percentage of participants who had achieved a complete response (CR) per RECIST 1.1. As per RECIST version 1.1, CR was defined as disappearance of all target lesions, any pathological lymph nodes (whether target or non-target) with reduced in the short axis to <10 mm.

    Measured: Up to 101 weeks

  4. Duration of Response (DOR) as Per RECIST v 1.1

    DOR was defined as the time from first occurrence of CR or PR until the first date of PD per RECIST version 1.1 or death. Per RECIST 1.1 criteria, CR was defined as disappearance of all target lesions, any pathological lymph nodes (whether target or non-target) with reduction in short axis to <10 mm. PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. PD was defined as at least a 20% increase in the sum of the longest diameter (SLD), taking as reference the smallest SLD recorded from baseline or the appearance of 1 or more new lesions.

    Measured: From first occurrence of CR or PR until disease progression or death, whichever occurs first (up to 24 months)

  5. Percentage of Participants With Disease Control Rate (DCR) as Per RECIST v 1.1

    Disease control rate was defined as percentage of participants who have a response of CR, PR, or at least 12 continuous weeks of stable disease (SD) as per RECIST v 1.1. As per RECIST v 1.1 before PD or initiating a new antineoplastic therapy, CR was defined as disappearance of all target lesions; any pathological lymph nodes (whether target or non-target) with reduction in short axis to <10 mm. PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (at least a 20% increase in the sum of diameters of target lesions) taking as reference the smallest sum diameters while on study. Percentage values were rounded off.

    Measured: Up to 24 months

  6. Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Serious TEAEs

    An adverse event was defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of study treatment, whether or not considered related to the study treatment. A serious adverse event (SAE) was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. A TEAE was defined as those AEs that develop or worsen after the first dose of study drug. TEAEs included both serious and non-serious TEAEs.

    Measured: From start of the study treatment up to 24 months

  7. Number of Participants With Clinically Significant Abnormalities in Clinical Laboratory Parameters

    Clinical laboratory parameters included clinical chemistry, hematology and urinalysis. Number of participants with clinically significant laboratory abnormalities which were deemed clinically significant by the investigator were reported.

    Measured: From start of the study treatment up to 24 months

  8. Number of Participants With Clinically Significant Changes in Vital Signs

    Vital signs included body temperature, blood pressure (systolic blood pressure and diastolic blood pressure). Measurements were made after the participant had been resting supine for a minimum of 5 minutes. The clinically significant change assessment was based on investigator's judgment. Number of participants with clinically significant change from baseline in vital signs values were reported.

    Measured: From start of the study treatment up to 24 months

  9. Number of Participants With Clinically Significant Changes in Physical Examination

    Number of participants with clinically significant physical examination abnormalities including general appearance, dermatological, head, eyes, ears, nose, throat, respiratory, cardiovascular, abdominal, lymph nodes, musculoskeletal, and neurological examinations. Number of participants with clinically significant physical examination abnormalities which were deemed clinically significant by the investigator were reported.

    Measured: From start of the study treatment up to 24 months

  10. Number of Participants With Severity of Adverse Events Assessed Using the NCI Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0

    AEs are graded using the following criteria using Common Terminology Criteria for Adverse events v5.0: Grade 1: Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated; Grade 2: Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental ADL; Grade 3: Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care ADL; Grade 4: Life-threatening consequences; urgent intervention indicated; Grade 5: Death related to AE.

    Measured: From start of the study treatment up to 24 months

A Phase 2 study testing Selinexor and Pembrolizumab in people with Locally Advanced Unresectable or Metastatic Melanoma, run by Karyopharm Therapeutics Inc at 13 sites 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 19 inclusion and 22 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: stopped early, as of the sponsor's last update on 23 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites 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 23 Aug 2024). 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 (ORR) Assessed as Per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 (time frame: From the date of randomization until the documentation of CR or PR, whichever occurs first (up to 24 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 23 Aug 2024.
