Brief Summary:
Up to 31 subjects diagnosed with oral squamous cell carcinoma will receive one application of a permeation enhancer and 2, 3 or 5 treatment applications of a Cisplatin drug-loaded patch to the tumor site at each of 4 treatment visits. These 4 treatment visits will be scheduled to occur during the 3 weeks prior to the standard of care tumor resection.

Condition or disease Intervention/treatment Phase
Oral Squamous Cell Carcinoma Drug: PRV111 (Cisplatin Transmucosal System) Phase 1 Phase 2

Detailed Description:

Up to 31 subjects diagnosed with oral squamous cell carcinoma will receive one application of a permeation enhancer and 2, 3 or 5 treatment applications of a Cisplatin drug-loaded patch to the tumor site at each of 4 treatment visits. These 4 treatment visits will be scheduled to occur during the 3 weeks prior to the standard of care tumor resection. After the surgery, subjects will be followed for 6 months for disease recurrence.

Ten subjects will be enrolled in Stage 1 of the study and will receive permeation enhancer and 3 treatment applications of the cisplatin drug-loaded patch at each treatment visit. Up to 21 additional subjects will enroll in Stage 2 for the purpose of 16 total evaluable subjects at the final dose for the efficacy analysis. In Stage 2, the dose may be escalated, de-escalated or remain the same based on the results in Stage 1. All subjects will be followed for 6 months post surgery for disease recurrence.

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

Arm Intervention/treatment
Experimental: Open-Label, Single Arm Study of PRV111
In Stage 1, subjects will receive 3 treatment applications of PRV111 (Cisplatin Transmucosal System) at each of the 4 planned visits within 3 weeks prior to their tumor surgery. Following review of Stage 1 subject data, additional subjects will be enrolled in Stage 2 and will receive 2, 3 or 5 treatment applications dependent on the results of Stage 1 at each of the 4 visits prior to their tumor surgery.
 Drug: PRV111 (Cisplatin Transmucosal System)
Each treatment visit will include one application of a permeation enhancer and then 2, 3 or 5 PRV111 (Cisplatin Transmucosal System) applications depending on the Stage subject is enrolled in.


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Determination of a safe and efficacious dose of PRV111 [ Time Frame: Subjects will be evaluated for safety and efficacy through study completion which is approximately 7 months. ]
    Based on the incidence of adverse events and tumor response


Secondary Outcome Measures :
  1. Evaluate tumor volume shrinkage [ Time Frame: Assessed within the 21 days prior to surgical excision of the tumor ]
    Assessed by imaging at baseline and at the time of surgical excision

  2. Assess long-term safety [ Time Frame: Assessed 1, 3 and 6 months post surgery ]
    Determine safety during post surgery follow-up visits by review of laboratory values and adverse events graded by CTCAE.

  3. Evaluate systemic, tumor and lymph node (if available) platinum levels following PRV111 administration [ Time Frame: Assessed for 21 days from baseline through surgical excision of the tumor ]
    Assessed using bioanalytical methods

  4. Evaluate device technical success including the residual cisplatin level in the patch after application [ Time Frame: Assessed during the 4 treatment visits in the 21 days prior to surgery ]
    Evaluate patch adhesion during application and residual cisplatin level post administration by bioanalytical methods.
