Safety and Efficacy Study of PRV211 in Subjects With Oral Squamous Cell Carcinoma

• Status: Not yet recruiting
• Trial end date: 2026-10-01
• Target enrollment: 0
• Participant gender: All

Summary

PRV211 is a sterilized nano engineered delivery system intended for intraoperative chemotherapy treatment for all solid tumor surgeries immediately following surgical excision. The goal is to treat the tumor bed locally, eliminating any remaining micro metastases or close margins that are unable to be fully resected while avoiding system circulation.

This study will enroll up to 40 subjects. In this study both safety and efficacy will be evaluated. All subjects will be monitored for possible DLTs.

• Phase: Phase 1/Phase 2
• Accepts Healthy Volunteers?: No

Criteria

Inclusion Criteria:

1. Adult subjects, men and women, defined by age ≥18 years at the time of screening.

2. Pathologically proven and clinically confirmed T2-T3, Nx-N2b, M0 SCC of the lip or oral cavity (anterior 2/3 of the tongue, floor of mouth, lower and upper gingiva, hard palate, and buccal mucosa).

3. Tumor must be amenable to surgical resection.

4. Clinically and/or radiologically measurable tumor.

5. Eastern Collaborative Oncology Group (ECOG) Performance Status of ≤2.

6. Candidates for standard of care treatment consisting of surgery.

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.

8. Absence of any serious underlying medical conditions which could impair the ability of the subject to participate in the study.

9. Have a life expectancy of ≥6 months.

10. Willing and able to provide written informed consent.

11. Able to return to study site for treatment and follow-up visits as defined in the Protocol.

Exclusion Criteria:

1. Concurrent documented malignancy, except for localized SCCs of the skin

2. Exposure to any investigational agent within 3 months prior to Screening

3. Known allergy or hypersensitivity to platinum-containing agents, or known intolerance to a prior platinum-containing agent, or to any of the excipients, which, in the judgement of the physician will preclude re-exposure to platinum-containing agent

4. Active, uncontrolled infection requiring systemic therapy, such as but not limited to HIV, Hepatitis B or C

5. Uncontrolled intercurrent illness that would risk subject safety, interfere with the objectives of the Protocol, or limit subject compliance with study requirements, as determined by the Investigator

6. Known or suspected pregnancy, planned pregnancy, or lactation

7. Any medical or psychiatric condition that may compromise the ability to give written informed consent
