About this study

Official title: Phase 1/2, Open-Label, Single-Arm Safety and Efficacy Dose-Finding, Systemic Exposure, and Device Technical Effects of PRV111 (Cisplatin Transmucosal System) in Subjects With Oral Squamous Cell Carcinoma

Up to 31 subjects diagnosed with oral squamous cell carcinoma received one application of a permeation enhancer 3 treatment applications of a Cisplatin drug-loaded patch to the tumor site at each of the 4 treatment visits. These 4 treatment visits were scheduled to occur during the 3 weeks prior to the standard of care tumor resection.

Read the detailed description

Up to 31 subjects diagnosed with oral squamous cell carcinoma received one application of a permeation enhancer and 3 treatment applications of a Cisplatin drug-loaded patch to the tumor site at each of 4 treatment visits. These 4 treatment visits were scheduled to occur during the 3 weeks prior to the standard of care tumor resection. After the surgery, subjects were followed for 6 months for disease recurrence.

Ten subjects were enrolled in the study. Up to 21 additional subjects could have been enrolled in Stage 2, if safety and efficacy endpoints were not met. The dose was not changed. All subjects were followed for 6 months post-surgery for disease recurrence.

During and at the conclusion of the treatment period, subjects were monitored for local and systemic safety, tumor response due to the treatment, and systemic drug exposure.

Open-Label, Single Arm Study of PRV111ExperimentalSubjects received 3 treatment applications of PRV111 (Cisplatin Transmucosal System) at each of the 4 planned visits within 3 weeks prior to their tumor surgery.
Receives: Drug: PRV111 (Cisplatin Transmucosal System)

What is being measured

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

  1. Determine an Efficacious Dose (mg/cm2) of PRV111 (Cisplatin Transmucosal System) Via Number of Tumor Responses

    The starting dose was 1.5 mg/cm2 of cisplatin. Based on the incidence of dose-limiting toxicities and tumor response, subjects would either continue to receive the starting dose or the dose would be de-escalated to 1.0 mg/cm2 or escalated to 2.5 mg/cm2.

    This measures presents the number of tumor responses during the PRV111 treatment period

    Measured: Subjects were evaluated for efficacy during the 4 treatment visits in the 21 days prior to surgery

  2. Determine a Safe Dose (mg/cm2) of PRV111 (Cisplatin Transmucosal System) Via Number of Dose-Limiting Toxicities

    The starting dose was 1.5 mg/cm2 of cisplatin. Based on the incidence of dose-limiting toxicities and tumor response, subjects would either continue to receive the starting dose or the dose would be de-escalated to 1.0 mg/cm2 or escalated to 2.5 mg/cm2.

    This measures presents the number of reported dose-limiting toxicities during the PRV111 treatment period

    Measured: 4 treatment visits in the 21 days prior to surgery

Secondary outcomes (5)
  1. Tumor Response (Tumor Volume Change From Baseline and Pre-op Visit, Approximately 21 Days Prior to Surgical Excision of the Tumor)

    Assessed by clinical measurement at baseline and at the pre-op visit

    Measured: Assessed within the 21 days prior to surgical excision of the tumor

  2. Number of Loco-regional Recurrences

    Number of loco-regional recurrences at follow-up

    Measured: Assessed 1, 3 and 6 months post surgery

  3. Tumor and Lymph Node (if Available) Platinum Levels

    Levels of platinum content in tumor tissue and/or lymph tissue, using a validated bioanalytical ICP-MS method. Resected tissues were digested via microwave and used to evaluate the amount of cisplatin delivered by PRV111 (Correlated to the amount of platinum detected).

    Measured: 21 days from baseline through surgical excision of the tumor

  4. Technical Success - Residual Cisplatin Levels Post-application

    Platinum content in each residual PRV111, using a validated bioanalytical ICP-MS method and the results for all applications were averaged.

    Measured: 4 treatment visits in the 21 days prior to surgery

  5. Systemic Platinum Levels (Cmax)

    Levels of platinum content in blood, using a validated bioanalytical ICP-MS method. Blood drawn was digested via microwave and used to evaluate the amount of systemic cisplatin exposure from PRV111 (Correlated to the amount of platinum detected). A single value for Cmax was calculated by averaging values for all subjects.

    Measured: Cmax is a single value of the highest concentration of platinum in the blood reported from samples taken post-dose across all 4 treatment visits (Baseline [0], 30, 60, and 120 minutes at Visits 1-4)

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing PRV111 (Cisplatin Transmucosal System) in people with Oral Squamous Cell Carcinoma, run by Privo Technologies at 5 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 11 inclusion and 7 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 21 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 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 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?

Yes. Results are posted in the registry (first posted 21 Oct 2022). 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?

Determine an Efficacious Dose (mg/cm2) of PRV111 (Cisplatin Transmucosal System) Via Number of Tumor Responses (time frame: Subjects were evaluated for efficacy during the 4 treatment visits in the 21 days prior to surgery). 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 NCT03502148, 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 21 Oct 2022.
