About this study

Official title: P1b, Open-Label, Safety, Tolerability, Efficacy Study of a Soluble Beta-glucan Odetiglucan in Combination w/ a CD40 Agonist (CDX-1140) in Patients w/ Metastatic Pancreatic Adenocarcinoma Whose Disease Did Not Progress During 1st-Line Chemo

The primary objective of this maintenance therapy study is to identify the maximum tolerated dose (MTD) and/ or recommended Phase 2 dose (RP2D), and evaluate the safety, tolerability, and dose-limiting toxicities (DLTs) of odetiglucan in combination with CDX-1140 in patients with metastatic PDAC with evidence of response or stable disease following a minimum of 16 and no more than 32 weeks of chemotherapy.

Up to 45 patients will be enrolled and dosed (30 patients in Part A and 15 in Part B).

Read the detailed description

This is a multiple institution, open-label, 2-part Phase 1b study to determine the MTD (and/ or RP2D), safety, tolerability, and preliminary efficacy of the combination of odetiglucan and CDX-1140 for the treatment of patients with metastatic PDAC with evidence of response or stable disease during a minimum of 16 and no more than 32 weeks of therapy immediately prior to study enrollment. Part A will identify the MTD and/ or RP2D in two cohorts of patients enrolled per ABA status (Cohort 1=ABA+ and Cohort 2=ABA-) and Part B will assess an alternative dosing regimen of RP2D in an anti-beta glucan antibody ABA+, ABA- or ABA mixed population (ABA+ and ABA-) based on observations in Part A.

Product: Odetiglucan and CDX-1140 5 Protocol/Amendment No.: PGG-PAN2111, Amd.0010 Confidential - HiberCell Inc.

In Part A, a 3 + 3 de-escalation design will be used to determine the MTD of CDX-1140 when administered in combination with odetiglucan (the starting dose for CDX-1140 is that anticipated to be the recommended phase 2 dose (RP2D) based on prior Phase 1 clinical assessment). Two cohorts of patients will be enrolled (ABA+ and ABA-) and proceed independently through the 3+3 de-escalation assessment; up to 30 patients will be enrolled. The following 2 treatment cohorts will be evaluated for safety, tolerability, and preliminary efficacy:

  • ABA+: Patients with ABA value ≥20 mcg/mL ABA
  • ABA-: Patients with ABA value <20 mcg/mL ABA

Both cohorts will initiate at Dose Level 1 and de-escalate to Dose Level -1 based on the respective 21-day DLT period:

  • Dose Level 1: Odetiglucan 4 mg/kg IV plus CDX-1140 1.5 mg/kg
  • Dose Level -1: Odetiglucan 4 mg/kg IV plus CDX-1140 0.72 mg/kg Treatment will be administered in 3-week cycles. Odetiglucan will be administered weekly on Days 1, 8, and 15 of each cycle followed ~15-30 minutes later by administration of CDX-1140 1.5 mg/kg or 0.72 mg/kg IV Day 1 of each cycle.

Part B, if opened, will enroll up to 15 patients to receive odetiglucan 4 mg/kg plus the CDX-1140 RP2D identified in Part A. As in Part A, treatment will be administered in 3-week cycles, however, both odetiglucan and CDX-1140 will be administered on Day 1 of each cycle (no odetiglucan administration on Days 8 and 15 as in Part A). If the RP2D differs between Cohort 1 and Cohort 2 at the end of Part A, the Sponsor in consult with the SMC, may select a single RP2D to investigate or investigate both RP2Ds. If a larger total enrollment is required, the protocol will be amended to support.

Study groups in NCT05484011
Study groupRoleWhat they receive
Part AExperimentalPatients will have regularly scheduled study visits on days 1, 8, and 15 of each cycle. On Day 1 patients will receive odetiglucan and CDX-1140. On Days 8 \& 15 only odetiglucan. Additional study visits may be required during some cycles for safety, efficacy, and translational assessments. Patients will dose to confirmed progression, a safety event or other administrative reason requiring discontinuation; all patients are allowed to dose up to 2 years (patients continuing to derive benefit may stay on treatment longer following consultation between Investigator and Sponsor). Following discontinuation patients will be followed up to 1 year.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing odetiglucan and CDX-1140 in people with Metastatic Pancreatic Adenocarcinoma, run by HiberCell, Inc. at 4 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 23 inclusion and 27 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 10 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 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 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: sponsor decision). 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?

Maximum Tolerated Dose (time frame: Within 24 months of last patient enrolled). 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 10 Apr 2024.
