View on ClinicalTrials.gov

Summary

This is a first-in-human clinical study to evaluate the safety, tolerability and efficacy of RXRG001 administered in the ducts of the parotid glands in adult patients with radiation-induced xerostomia (dry mouth) and hyposalivation (reduced saliva production). In Part 1 of the study (open-label, single-arm), patients will receive unilateral administrations of RXRG001 in 3 single ascending dose cohorts and in 3 multiple ascending dose cohorts. Part 2 of the study has a randomized, double-blind, placebo-controlled design. Patients will receive bilateral administrations of RXRG001 in 3 multiple ascending dose cohorts.

Official title: A Phase I/IIa, Dose Escalation Study Evaluating the Safety, Tolerability, and Preliminary Efficacy of Intraductal Administration of RXRG001 to Parotid Gland(s) in Adults With Radiation-Induced Xerostomia and Hyposalivation
