What is being measured

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

  1. Percentage of Participants With Objective Response Rate

    Objective Response Rate (ORR) is defined as the proportion of patients with best overall response (BOR) of confirmed partial response (PR) or complete response (CR) from the time of study treatment initiation until progression of disease (PD) as determined by the Investigator using Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. Progression (PD) is defined per RECIST v1.1 as at least a 20% increase in the sum of diameters of target lesions and an absolute increase of at least 5 mm, or unequivocal progression of non-target lesions, or the appearance of one or more new lesions.

    Measured: From the start of study treatment to radiographically confirmed disease progression (PD) per RECIST v1.1, assessed at screening, every 6 weeks (±7 days) for the first 12 weeks, and every 12 weeks (±7 days) thereafter, up to 22 months.

Secondary outcomes (6)
  1. Percentage of Participants With Treatment-Emergent Adverse Events (TEAEs) and Treatment-Related Adverse Events.

    The percentage of participants experiencing at least one treatment-emergent adverse event (TEAE) and treatment-related adverse event. Adverse events are defined as treatment-emergent (TEAEs) if they began or worsened on or after the first administration of study drug through 28 days after the last administration. Severity of adverse events is graded per the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v5.0.

    Measured: From first dose of study treatment through end of treatment (estimated up to 18 months) plus safety follow-up of 30 days after the last dose.

  2. Duration of Response (DOR)

    Duration of Response (DOR) is determined for patients with a best overall response (BOR) of confirmed complete response (CR) or partial response (PR), defined as the time from the scan first showing response by RECIST v1.1 to disease progression (PD) or death from any cause. Progression (PD) is defined per RECIST v1.1 as at least a 20% increase in the sum of diameters of target lesions and an absolute increase of at least 5 mm, or unequivocal progression of non-target lesions, or the appearance of one or more new lesions.

    Measured: From first documented response (CR or PR) to radiographically confirmed disease progression (PD) per RECIST v1.1 or death from any cause, assessed at screening, every 6 weeks for the first 12 weeks, and every 12 weeks thereafter, up to 22 months

  3. Disease Control Rate (DCR)

    Disease Control Rate (DCR) is defined as the proportion of patients achieving a best overall response (BOR) of confirmed complete response (CR), partial response (PR) (either of any duration), or stable disease (SD) lasting >=12 weeks by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 following study treatment initiation. Progression (PD) is defined per RECIST v1.1 as at least a 20% increase in the sum of diameters of target lesions and an absolute increase of at least 5 mm, or unequivocal progression of non-target lesions, or the appearance of one or more new lesions.

    Measured: From the start of study treatment to radiographically confirmed disease progression (PD) per RECIST v1.1, assessed at screening, every 6 weeks for the first 12 weeks, and every 12 weeks thereafter, up to 22 months

  4. Time to Response (TTR)

    Time to Response (TTR) is defined as the time from the first dose of study medication to the initial measurement of complete response (CR) or partial response (PR), where CR or PR is subsequently confirmed by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. Progression (PD) is defined per RECIST v1.1 as at least a 20% increase in the sum of diameters of target lesions and an absolute increase of at least 5 mm, or unequivocal progression of non-target lesions, or the appearance of one or more new lesions.

    Measured: From the first dose of study treatment to the initial documentation of complete response (CR) or partial response (PR) per RECIST v1.1 , assessed at screening, every 6 weeks for the first 12 weeks, and every 12 weeks thereafter, up to 22 months

  5. Progression-free Survival(PFS)

    Number of months from study treatment initiation to the date of disease progression or death due to any cause

    Measured: From first dose of study treatment until the date of first documented disease progression or death from any cause, whichever occurs first, assessed every 6 weeks for the first 12 weeks and every 12 weeks thereafter, up to approximately 21 months

  6. Overall Survival(OS)

    Number of months from study treatment initiation to the date of death due to any cause

    Measured: From first dose of study treatment until the date of death from any cause, assessed approximately every 12 weeks following the end-of-treatment visit, up to approximately 24 months.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing nab-sirolimus in people with Neuroendocrine Tumors and NET, run by Aadi Bioscience, Inc. at 4 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 27 inclusion and 16 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 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 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 25 Aug 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?

Percentage of Participants With Objective Response Rate (time frame: From the start of study treatment to radiographically confirmed disease progression (PD) per RECIST v1.1, assessed at screening, every 6 weeks (±7 days) for the first 12 weeks, and every 12 weeks (±7 days) thereafter, up to 22 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 25 Aug 2026.
