What is being measured

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

  1. Objective Response Rate (ORR)

    ORR defined as the proportion of participants who achieved a best overall Response (BOR) of CR or PR per RECIST Version 1.1 from randomization until disease progression, or death due to any cause, as determined by blinded independent central review.

    Measured: Up to approximately 1 year

Secondary outcomes (11)
  1. Progression Free Survival (PFS)

    PFS defined as the time from the date of randomization to the earliest documented disease progression per RECIST version 1.1, or death due to any cause, as determined by blinded independent central review.

    Measured: Up to approximately 1 year

  2. Duration of Response (DOR)

    DOR defined as the time from the date of first documentation of objective tumor response (CR or PR) to the earliest documented disease progression per RECIST version 1.1, or death due to any cause, as determined by blinded independent central review.

    Measured: Up to approximately 1 year

  3. Number of Participants with an Adverse Event (AE)

    Type, incidence, causality and severity of AEs based on National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) Version 5.0. Clinically significant changes from baseline in vital signs, laboratory parameters, electrocardiograms (ECGs), weight, and Eastern Cooperative Oncology Group (ECOG) performance status will be recorded as AEs.

    Measured: Up to approximately 1 year

  4. Disease Control Rate (DCR)

    DCR defined as CR plus PR plus stable disease (SD), as determined by independent central review.

    Measured: Up to approximately 1 year

  5. Overall Survival (OS)

    OS defined as the time from drug administration to death due to any cause.

    Measured: Up to approximately 1 year

  6. Overall Response (OR)

    Defined as CR or PR, PFS, DCR, DOR, and OS associated with a reduction in circulating tumor DNA (ctDNA) mutation allele frequency (MAF).

    Measured: Up to approximately 1 year

  7. Maximum Concentration (Cmax) of Onvansertib and metabolites in combination w/FOLFIRI and bevacizumab or FOLFOX and bevacizumab

    Measured: Day 1 and Day 5 of Cycle 1, and Day 5 of Cycle 3 (cycle is 28 days)

  8. Area Under the Plasma Concentration Curve (AUC) of Onvansertib and metabolites in combination w/FOLFIRI and bevacizumab or FOLFOX and bevacizumab

    Measured: Day 1 and Day 5 of Cycle 1, and Day 5 of Cycle 3 (cycle is 28 days)

  9. Trough Concentration (Ctrough) of Onvansertib and metabolites in combination w/FOLFIRI and bevacizumab or FOLFOX and bevacizumab

    Measured: Day 1 and Day 5 of Cycle 1, and Day 5 of Cycle 3 (cycle is 28 days)

  10. Efficacy: Exposure Response Evaluation of Onvansertib

    Measured: Up to approximately 1 year

  11. Safety: Exposure Response Evaluation of Onvansertib

    Measured: Up to approximately 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Onvansertib, FOLFIRI and Bevacizumab in people with Metastatic Colorectal Cancer and CRC, run by Cardiff Oncology at 41 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 8 inclusion and 13 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 16 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 41 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?

This study is still under way. Results are not available in the source record yet.

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?

Objective Response Rate (ORR) (time frame: Up to approximately 1 year). 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 NCT06106308, which also lists 1 linked publication.

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 16 Jun 2026.
