MeiraGTx to Present 12-month Data from All Cohorts of the Completed Phase 1 AQUAx Clinical Study and an Update on the Company’s Recently Initiated Phase 2 Study of AAV-hAQP1 for the Treatment of Grade 2/3 Radiation-Induced Xerostomia on Tuesday, June 27,
June 22, 2023
LONDON and NEW YORK, June 22, 2023 (GLOBE NEWSWIRE) -- MeiraGTx Holdings plc (NASDAQ: MGTX), a vertically integrated, clinical stage gene therapy company, today announced it will host a conference call and webcast to present an update on the Company’s AAV-hAQP1 clinical program for the treatment of grade 2/3 radiation-induced xerostomia (RIX) on Tuesday, June 27, 2023, at 8:00 a.m. ET.
The presentation will include:
1) Data from the completed Phase 1 AQUAx clinical study for the 24 patients treated with AAV-hAQP1 in the unilateral and bilateral cohorts:
- Safety and tolerability
- 12-month data for PRO assessments of xerostomia symptoms in the unilateral cohorts (n=12)
- 12-month data for PRO assessments of xerostomia symptoms in the bilateral cohorts (n=12)
- Change over time in the objective measure of saliva flow out to 12 months for both bilateral and unilateral cohorts
- Long-term follow up data to 2 or 3 years for the participants who have reached those timepoints
2) Summary of biopsy data from a subset of patients in the Phase 1 National Institutes of Health (NIH) study of AAV-hAQP1 in RIX demonstrating parotid transduction and durability out to at least 24-months post-treatment.
3) Overview of the recently initiated randomized, double blind, placebo-controlled Phase 2 study of AAV-hAQP1 for the treatment of RIX, now enrolling patients.
A question-and-answer session will follow the formal presentation.

About the Phase 1 AQUAx Clinical Trial
The Phase 1 AQUAx clinical trial is an open-label, non-randomized, dose escalation trial designed to evaluate the safety of MeiraGTx’s investigational gene therapy AAV-hAQP1 when administered via Stensen's duct to one or both parotid glands in patients who have been diagnosed with grade 2 or 3 radiation-induced xerostomia and who have remained cancer free for at least five years (or at least two years if HPV+) after receiving radiation treatment for head and neck cancer. Primary endpoint of the trial is safety, with efficacy endpoints including patient reported measures of xerostomia symptoms and the evaluation of the change in parotid gland salivary output after treatment with AAV-hAQP1.
About the Phase 1 NIH Study
The Phase 1 NIH study is an open-label, dose-escalation study evaluating the safety of a single administration of an adeno-associated virus vector encoding human aquaporin-1 to one parotid salivary gland in individuals with irradiation-induced parotid salivary hypofunction.
MeiraGTx (Nasdaq: MGTX) is a vertically integrated, clinical stage gene therapy company with six programs in clinical development and a broad pipeline of preclinical and research programs. MeiraGTx has core capabilities in viral vector design and optimization and gene therapy manufacturing, and a transformative gene regulation platform technology which allows tight, dose responsive control of gene expression by oral small molecules with dynamic range that can exceed 5000-fold. Led by an experienced management team, MeiraGTx has taken a portfolio approach by licensing, acquiring, and developing technologies that give depth across both product candidates and indications. MeiraGTx’s initial focus is on three distinct areas of unmet medical need: ocular, including inherited retinal diseases and large degenerative ocular diseases, neurodegenerative diseases, and severe forms of xerostomia. Though initially focusing on the eye, central nervous system, and salivary gland, MeiraGTx plans to expand its focus to develop additional gene therapy treatments for patients suffering from a range of serious diseases.
