About this study

Official title: A Phase 2/3 Study of Navtemadlin as Maintenance Therapy in Subjects With TP53WT Advanced or Recurrent Endometrial Cancer Who Responded to Chemotherapy

This study evaluates navtemadlin as maintenance treatment for patients with advanced or recurrent endometrial cancer (EC) who have achieved complete response or partial response on chemotherapy.

The study will be conducted in 2 parts. Part 1 will evaluate safety and efficacy of two different doses of navtemadlin alongside an observational control arm to determine the Phase 3 navtemadlin dose. Part 2 will evaluate the efficacy and safety of navtemadlin Phase 3 dose compared to placebo.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • NavtemadlinDrug

    Also called KRT-232

    Navtemadlin is an experimental MDM2 anticancer drug taken by mouth

  • Navtemadlin PlaceboDrug

    Navtemadlin placebo is a placebo that is the same in appearance to navtemadlin drug taken by mouth

What is being measured

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

  1. Part 1: To determine the navtemadlin Phase 3 dose

    Safety review committee (SRC) will determine the navtemadlin Phase 3 dose for Part 2 based on safety data from Part 1

    Measured: 12 months

  2. Part 2: To compare progression-free (PFS) survival by independent review committee (IRC) between navtemadlin and placebo

    PFS defined as the time from randomization to disease progression by IRC or death, whichever occurs first

    Measured: 50 months

Secondary outcomes (6)
  1. Part 1: To evaluate the treatment effect of navtemadlin on PFS by IRC and investigator assessment

    PFS defined as the time from randomization to disease progression by IRC/investigator assessment or death, whichever occurs first

    Measured: 50 months

  2. Part 2: To evaluate the treatment effect of navtemadlin on the time to first subsequent treatment (TFST)

    TFST defined as the time from randomization to initiation of first subsequent anticancer therapy or death, whichever occurs first

    Measured: 50 months

  3. Parts 1 and 2: To determine the pharmacokinetic (PK) profile of navtemadlin

    Will determine the Maximum observed concentration (Cmax)

    Measured: 1 day

  4. Parts 1 and 2: To determine the pharmacokinetic (PK) profile of navtemadlin

    Will determine the area under the plasma concentration versus time curve (AUC)

    Measured: 1 day

  5. Parts 1 and 2: To determine the pharmacokinetic (PK) profile of navtemadlin

    Will determine the time of maximum plasma concentration (Tmax)

    Measured: 1 day

  6. Parts 1 and 2: To evaluate the treatment effect of navtemadlin on the disease control rate (DCR)

    Best response of complete response (CR), partial response (PR) or stable disease (SD) by IRC/investigator assessment among subjects with PR as best response from prior chemotherapy

    Measured: 50 months

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Navtemadlin in people with Endometrial Cancer, run by Kartos Therapeutics, Inc. at 83 sites in 17 countries.

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 4 inclusion and 6 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: looking for participants now, as of the sponsor's last update on 2 May 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 83 sites in United States, Italy, Poland, Spain, Romania and 12 more countries. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined 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.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Contact John Mei (650-542-0136, jmei@kartosthera.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Part 1: To determine the navtemadlin Phase 3 dose (time frame: 12 months). The study lists 2 primary outcomes in all. 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 May 2024.
