About this study

Official title: A Phase 2 Study of 9-ING-41, a Glycogen Synthase Kinase 3-beta (GSK-3β) Inhibitor, Combined With Retifanlimab, a PD-1 Inhibitor, Plus Gemcitabine/Nab-Paclitaxel as Frontline Therapy for Patients With Advanced Pancreatic Adenocarcinoma (RiLEY)

This trial examines how Pancreatic Adenocarcinoma reacts to the addition of 9-ING-41 and retifanlimab to the standard of care chemotherapy treatment, to see if using this combination will help and is able to effect disease progression.

Read the detailed description

Given the role of GSK-3β in immune regulation, the combination of GSK-3β inhibition with PD 1 inhibition may be expected to provide synergistic anti-tumor efficacy. The excellent safety profile of 9-ING-41, along with preclinical and clinical evidence of anti-tumor activity in pancreatic cancer, provides a strong rationale to evaluate the efficacy of 9-ING-41 in combination with a PD 1 inhibitor plus standard chemotherapy (gemcitabine/nab-paclitaxel) as frontline therapy for patients with advanced PDAC.

The combination of 9-ING-41 and retifanlimab with gemcitabine/nab-paclitaxel has not previously been administered to human subjects. In the 1801 study, 9-ING- 41 has been administered in combination with various chemotherapy regimens including gemcitabine/nab-paclitaxel, with one 9-ING-41-related SAE (transient visual change) documented to date. Retifanlimab alone has been well-tolerated when administered for up to 2 years in patients with anal cancer. Overall, based on previous nonclinical and clinical experience, both of these agents appear to have an acceptable safety profile and do not appear to have significant overlapping toxicities. However, it is possible that when they are administered together and in combination with gemcitabine/nab-paclitaxel, more frequent or severe AEs, or new AEs not previously observed with any of these agents administered alone, may occur.

It is not known if administration of 9-ING-41 and retifanlimab will act synergistically to provide increased anti-tumor activity compared to gemcitabine/nab-paclitaxel alone. Subjects in this study should not expect to benefit directly by their participation in the study. The data collected in this study may benefit future cancer patients.

What is being measured

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

  1. Disease Control Rate (DCR)

    Percentage of patients with stable disease (SD), Complete Response (CR), or Partial Response (PR) for ≥16 weeks during treatment. Per RECIST v1.1, (CR): Disappearance of all target lesions. Any pathological lymph nodes (target or nontarget) with reduction in short axis to <10 mm. (PR): ≥30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study. Progressive Disease (PD): At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression).

    Measured: Up to approximately 11 months from baseline

Per RECISIT v1.1, Progressive Disease (PD) is ≥20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). The sum must also demonstrate an absolute increase of ≥5 mm. The appearance ≥1 new lesion(s) is considered progression.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing 9-ING-41, Retifanlimab and Gemcitabine in people with Pancreatic Adenocarcinoma, run by Anwaar Saeed at 2 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 10 inclusion and 20 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 17 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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?

Yes. Results are posted in the registry (first posted 17 Jul 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Disease Control Rate (DCR) (time frame: Up to approximately 11 months from baseline). 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 NCT05239182, 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 17 Jul 2025.
