About this study

Official title: A Phase 1 First-in-Human Study of KO-947 in Locally Advanced Unresectable or Metastatic, Relapsed and/or Refractory Non-Hematological Malignancies

This phase 1 first-in-human (FIH) dose escalation study will determine the maximum tolerated dose (MTD) of KO-947 in subjects with locally advanced unresectable or metastatic, relapsed and/or refractory, non-hematological malignancies. If an MTD cannot be identified, a recommended phase 2 dose (RP2D) will be determined. In addition, two tumor specific extension cohorts may be conducted to further characterize the safety and tolerability of KO-947 and provide preliminary evidence of anti-tumor activity.

Read the detailed description

This phase 1 first-in-human (FIH) dose escalation study will determine the maximum tolerated dose (MTD) of KO-947 in subjects with locally advanced unresectable or metastatic, relapsed and/or refractory, non-hematological malignancies. If an MTD cannot be identified, a recommended phase 2 dose (RP2D) will be determined. In addition, two tumor specific extension cohorts may be conducted to further characterize the safety and tolerability of KO-947 and provide preliminary evidence of anti-tumor activity. Three dosing schedules will be executed (Schedule 1, 2, or 3).

Screening evaluations will be completed following signing of informed consent and within either 21 days or 28 days of Cycle 1 Day 1. Evaluations performed as part of the standard of care within 21/28 days of dosing but prior to consent do not need to be repeated. By signing the consent form, study subjects agree to the collection of standard of care health information.

The study will consist of three parts: dose escalation, MTD expansion and tumor specific extension.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing KO-947 in people with Advanced Malignant Neoplasm, run by Kura Oncology, Inc. at 5 sites in 2 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 19 inclusion and 11 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 20 Sep 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in United States, Spain. 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?

The study was stopped early (reason given: Due to a strategic business decision Kura has stopped development of KO-947. Neither safety nor efficacy reasons were the cause of study termination.). Results are not available in the source record.

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?

To determine the maximal tolerated dose (MTD) and/or the recommended Phase 2 dose (RP2D) of KO-947 in subjects with locally advanced unresectable or metastatic, relapsed and/or refractory, non-hematological malignancies. (time frame: Dose-limiting toxicities will be evaluated during the first 28 days of KO-947 monotherapy treatment in the dose escalation portion of the study.). 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 20 Sep 2021.
