PRV™ System

The PRV (Programmed Release Vehicle) platform enables targeted drug delivery, supports the body’s own immune and reparative responses, and is used in the design of safer, less invasive alternatives to currently available treatments.

The PRV system is used in multiple dosage forms. Formulations include topically and intraoperatively administered patches and hydrogels. Drug compounds within dosage forms are kept stable and are engineered to maximize potency. The rate and location of drug release is triggered by parameters that may be adapted to particular physiological environments.

Unlocking Locoregional Oncology Market

Head and neck squamous cell carcinoma

  • Incidence in the US: ~53,000 
  • Prevalence: ~370,300
  • No safe, effective neoadjuvant treatment exists

PRV211- Pivotal Stage Treatment
Intraoperative chemotherapy & Immunomodulation in solid tumors

  • ~4,000,000 cancer surgeries in the US  
  • Prevalence: ~1,806,590
  • No safe, effective intraoperative treatment exists.

PRV131 – Controlled Release Long Lasting Intraumoral Injectable

  • Effective tratment for all solid tumors
  • Intial Indications: Lung Cancer, Head and Neck Cancer, Colon Cancer
  • Highly potent locolized, highly concentrated antitumer treatment with negligible side effects



The PRV™ system is currently used for locoregional treatment of cancerous tumors. Additional formulations and treatment strategies comprising compounds for indications outside of oncology are under development, with promising results.

The proprietary manufacturing processes implemented in our in-house GMP facility allows Privo to produce and develop PRV-based therapeutics and scale production to meet clinical needs.
