Sponsor: Privo Technologies
Summary
Arm 1 ( Phase 2/3 Run in ): PRV111: Topical Locoregional Delivery Placed Over the Tumor Region Primary Endpoint: Overall Response Rate (ORR) Primary Objective: Demonstrate the safety and efficacy of PRV111 in patients with Carcinoma in Situ (CIS) (WHO 2017) Arm 2 (Phase 1) PRV211: Intraoperative Locoregional Delivery Placed into the Resected Tumor Bed Primary Endpoint: Safety Primary Objective: Determine Safety of PRV211 in intraoperative setting Subject Assignment: Subjects will be assigned to Arm 1 or Arm 2 of this study based on disease staging Arm 1: Pathologically proven and clinically confirmed Tis/CIS of the lip or oral cavity Arm 2: Pathologically proven and clinically confirmed T1-T3, Nx, M0 of the lip or oral cavity
Official title: Phase 2/3 Run in, Open-Label, Two Arm Study for Safety, Efficacy and Tolerability of PRV111 (Cisplatin Transmucosal System) & PRV211 (Intraoperative Cisplatin System) in Subjects Amenable to Surgery

PRV211 (Intraoperative Cisplatin System)
PRV211 system is comprised of two parts, a liquid permeation enhancer (PE) and cisplatin patch. The permeation is brushed onto the resected tumor bed and after 5 minutes the patch can be applied directly over the same area. Apply up to 2 layers of the PRV211 system to the tumor bed post-resection. The duration of the PRV211 treatment takes approximately 10-20 minutes and then the surgeon can continue as planned with the rest of the standard of care procedure. The proposed starting dose is 0.5 mg/cm2 of cisplatin on the tumor bed. This approach can be safe and effective in preventing locoregional recurrence after surgery and eliminating high-risk factors for local recurrence, such as dysplasia at the margins.
PRV111 (Cisplatin Transmucosal System)
PRV111 (Cisplatin Transmucosal System) is a thin, 2-layer, matrix-type, transmucosal patch consisting of a chitosan matrix layer embedded with cisplatin loaded chitosan particles (CLPs) and a non-woven fabric adhesive unidirectional backing, which is applied to the matrix layer during manufacturing. The patch is self-adhesive. In addition to the PRV111 patch, a separately packaged Permeation Enhancer (PE) Powder for Reconstitution used in conjunction with PRV111. The reconstituted PE Solution is intended to improve the absorption of the cisplatin active ingredient and will be applied prior to patch application.
