What is being measured

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

  1. Overall Response Based on RECIST V1.1 Following Oral Doses of Pexidartinib (Efficacy Analysis Set)

    For the assessment of tumor response, participants were classified into the best of the following tumor response categories by RECIST v1.1: complete response (CR), disappearance of all target lesions and normalization of tumor marker level; partial response (PR), at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters; stable disease (SD); neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease, taking as reference the smallest sum diameters while on study; progressive disease (PD), at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study and the sum must also demonstrate an absolute increase of at least 5 mm; or not evaluable (NE) for analysis. Objective response rate was defined as CR or PR and disease control rate was defined as CR, PR, or SD.

    Measured: Day 1 through Day 28 after last dose (within 18 months)

Secondary outcomes (13)
  1. Duration of Response or Duration of Stable Disease Following Oral Doses of Pexidartinib (Efficacy Analysis Set)

    Based on RECIST v1.1, complete response (CR), disappearance of all target lesions and normalization of tumor marker level; partial response (PR), at least a 30% decrease in sum of diameters of target lesions, with reference to baseline sum diameters; stable disease (SD); neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD), with reference to smallest sum diameters; PD, at least a 20% increase in the sum of diameters of target lesions, with reference to smallest sum on study and sum must also demonstrate an absolute increase of at least 5 mm; Duration of response for responders (CR or PR) is defined as the time interval between the date of the earliest qualifying response and the date of PD or death for any cause, whichever occurs earlier. Duration of SD is defined as the time interval, in the absence of either CR or PR that will be calculated between the date of the first administration of the study drug and the date of PD.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Pexidartinib in people with Advanced Solid Tumors, run by Daiichi Sankyo Co., Ltd. at 1 site in Taiwan.

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 10 inclusion and 9 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: finished, as of the sponsor's last update on 25 Apr 2022. 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 Taiwan. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 24 Apr 2020). 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 Based on RECIST V1.1 Following Oral Doses of Pexidartinib (Efficacy Analysis Set) (time frame: Day 1 through Day 28 after last dose (within 18 months)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02734433, which also lists 2 linked publications.

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 25 Apr 2022.
