7. Male and female subjects of childbearing potential must agree to use 2 methods of effective contraception from screening and for at least 30 days after the final dose of investigational product. Appropriate birth control is defined as barrier methods with spermicides, oral or parenteral contraceptives and/or intrauterine devices, or naturally or surgically sterile (with documentation in the subject's medical records). Postmenopausal women are defined as presenting at least 12 months' natural spontaneous amenorrhea, or at least 6 weeks following surgical menopause (bilateral oophorectomy). Females of childbearing potential must be non-lactating and have a negative serum hCG within 14 days of treatment initiation.

Interventions

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.

PRV131 (Cisplatin Intratumoral Injectable)

PRV131 is a nanoparticle-based cisplatin formulation designed for intratumoral administration. The product is supplied as a lyophilized powder and reconstituted with a separately packaged diluent to form a suspension for injection. The reconstituted suspension is administered directly into the tumor, with dosing customized based on tumor size and injection site distribution. Upon intratumoral administration, the nanoparticles facilitate deep tumor penetration and localized drug release, enabling high local cisplatin concentrations while minimizing systemic exposure.

Primary outcome measure

  • Overall Response Rate (ORR) [ Time Frame: 6-7 months ]
  • Safety assessed via dose-limiting toxicities [ Time Frame: 1-month post-surgery and through study completion, ~12-14 months ]
