What participants receive

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

  • CTX130Biological

    CTX130 CD70-directed T-cell immunotherapy comprised of allogeneic T cells genetically modified ex vivo using CRISPR-Cas9 gene editing components.

What is being measured

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

  1. Part A (dose escalation): Incidence of adverse events

    Adverse events defined as dose-limiting toxicities

    Measured: From CTX130 infusion up to 28 days post-infusion

  2. Part B (cohort expansion): Objective response rate

    Objective response rate per Response Evaluation Criteria In Solid Tumors (RECIST) v1.1

    Measured: From CTX130 infusion up to 60 months post-infusion]

Secondary outcomes (2)
  1. Progression Free Survival

    Measured: From date of CTX130 infusion until date of disease progression or death due to any cause, assessed up to 60 months

  2. Overall Survival

    Measured: From date of CTX130 until date of death due to any cause, assessed up to 60 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CTX130 in people with Renal Cell Carcinoma, run by CRISPR Therapeutics AG at 7 sites in 4 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

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 8 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in United States, Australia, Canada, Netherlands. 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: Patients to be followed up in the CRSP-ONC-LTF study). 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?

Part A (dose escalation): Incidence of adverse events (time frame: From CTX130 infusion up to 28 days post-infusion). 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?

On the ClinicalTrials.gov record for NCT04438083, 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 8 Jan 2025.
