About this study

Official title: Tomivosertib (eFT-508) in Combination With PD-1/PD-L1 Inhibitor Therapy: A Study of Subjects Administered Anti-PD-1/Anti-PD-L1 Therapy That Are Experiencing Insufficient Response to Checkpoint Inhibitor Alone

Phase 2, open-label study that will evaluate the safety, tolerability, antitumor activities.

Read the detailed description

This Phase 2, open-label study will evaluate the safety, tolerability, antitumor activity, and pharmacokinetics (PK) of Tomivosertib (eFT-508) in subjects who have initiated anti-PD-1/anti-PD-L1 monotherapy and either developed progressive disease (PD) per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 on therapy or have undergone 12 weeks of anti-PD-1/anti-PD-L1 therapy with no evidence of partial response (PR) or complete response (CR).

    Also called MNK1 and MNK2

    Tomivosertib (eFT-508) is a novel, small-molecule investigational drug being developed by eFFECTOR Therapeutics, as an antitumor therapy that acts by selectively inhibiting mitogen-activated protein kinase (MAPK)-interacting serine/threonine kinase (MNK)1 and MNK 2.

Study groupRoleWhat they receive
Tomivosertib (eFT-508)ExperimentalTomivosertib (eFT-508) will be taken at 200 mg twice daily (bid). Subjects will continue their anti-PD-1/anti-PD-L1 therapy, which they had already initiated per standard of care according to the package insert.
Receives: Drug: Tomivosertib (eFT-508)

What is being measured

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

  1. Proportion of subjects with treatment-emergent AEs (TEAEs) and serious AEs (SAEs)

    The incidence of TEAEs and SAEs will be summarized and TEAEs will also be summarized by severity and according to their relationship to Tomivosertib (eFT-508).

    Measured: 52 weeks

  2. Overall Response Rate (ORR) as determined by RECIST 1.1

    Defined as the proportion of subjects who achieve a best overall response of complete response (CR) or partial response (PR).

    Measured: 52 weeks

  3. Progression Free Survival (PFS) as determined by RECIST 1.1

    Defined as the interval from the start of Tomivosertib (eFT-508) to the occurrence of PD or death from any cause.

    Measured: 52 weeks

Secondary outcomes (3)
  1. ORR as determined by iRECIST

    Defined as the proportion of subjects who achieve a best overall response of CR assigned using iRECIST (iCR) or PR assigned using iRECIST (iPR).

    Measured: 52 weeks

  2. PFS as determined by iRECIST

    Defined as the interval from the start of Tomivosertib (eFT-508) to the occurrence of confirmed progression assigned using iRECIST (iCPD) or death from any cause.

    Measured: 52 weeks

  3. Overall survival

    Defined as time from the first dose date of Tomivosertib (eFT-508) to death due to any cause will be summarized.

    Measured: 52 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Tomivosertib (eFT-508) in people with Solid Tumors, run by Effector Therapeutics at 19 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 34 inclusion and 22 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 22 Mar 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 19 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Proportion of subjects with treatment-emergent AEs (TEAEs) and serious AEs (SAEs) (time frame: 52 weeks). The study lists 3 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 NCT03616834, 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 22 Mar 2023.
