Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Open-Label, Single Arm Study of PRV111

Arm Description

Subjects received 3 treatment applications of PRV111 (Cisplatin Transmucosal System) at each of the 4 planned visits within 3 weeks prior to their tumor surgery.

Outcomes

Primary Outcome Measures

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
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

Secondary Outcome Measures

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
Number of Loco-regional Recurrences
Number of loco-regional recurrences at follow-up
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).
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.
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.

5. Study Description

Brief Summary
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. Funding Source: FDA OOPD
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.
