About this study

Official title: Phase II, Randomized, Double-blinded, Placebo-Control, Toxicity/Efficacy Study on the Transfer of Adenovirus With the CD40 Ligand Gene (AdcuCD40L) to Patients With Stage I, II or III Esophageal Carcinoma

This study is a randomized, double-blinded assessment of biologic efficacy of AdcuCD40L. The individuals enrolled in this study will be individuals with biopsy proven resectable esophageal carcinoma. The dose of the AdcuCD40L vector (administered endoscopically directly to the tumor) will be the highest tolerable dose (most likely 10^11 particle units) determined from Weill-IRB protocol #0011004683 dose escalation study.

Read the detailed description

This study is designed to add to the safety profile data as well as assessing biologic efficacy parameters. It will include 24 individuals with biopsy proven, resectable, stage I-III esophageal cancer. Because there may be immune responses attributable to the gene therapy vector itself, independent of the CD40L transgene, this part of the study is designed in a randomized, blinded fashion to compare intratumoral administration of the AdcuCD40L vector compared to a placebo. Because there are likely differences over time in the pattern of the biologic response to the expression of CD40L in the tumor (including activation and trafficking of DC, and recruitment and activation of immune cells), this study will include 2 "time" cohorts (based on the time between administration of the AdcuCD40L vector and the time of surgery to remove the tumor). Using Weill-IRB protocol #0011004683 dose escalation study to determine the highest non-toxic dose of the AdcuCD40L vector, this dose (likely 10^11 particle units) will be used for all individuals enrolled in this efficacy study. The placebo will be the salt water-sugar solution used as a vehicle for the vector. Since there is no evidence that delay of surgery for solid tumors for 15 days following diagnosis alters the prognosis, surgery for removal of the primary tumor will be carried out at either 5 or 15 days after administration of the vector (n= 12/group, including n=6 receiving the AdcuCD40L vector, and n=6 receiving placebo). This will permit assessment of the resulting data (in a randomized, blinded fashion) and the biologic responses to the AdCUCD40L vector over time. In addition to safety/toxicity parameters, the primary tumor, regional and distant nodes removed at the time of surgery, and peripheral blood will be assessed for biologic parameters relevant to responses to the AdcuCD40L vector.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing AdcuCD40L in people with Esophageal Neoplasms, run by Weill Medical College of Cornell University.

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 15 inclusion and 14 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: withdrawn, as of the sponsor's last update on 4 May 2016. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined 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.

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 was withdrawn before enrolling participants, so there are no results.

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?

Expression of CD40L and cytokines (time frame: 5-15 days). 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 4 May 2016.
