Glenmark presents new data on Ryaltris for seasonal allergic rhinitis treatment at AAAAI/WAO joint congress in Florida

“Glenmark has a long history of expertise in respiratory diseases, and is committed to developing new and innovative treatments,” said Fred Grossman, president and chief medical officer at Glenmark Pharmaceuticals. “We have studied the safety and efficacy of Ryaltris in more than a thousand patients over several years, and we are pleased to share these data at the AAAAI/WAO Joint Congress.”

Data included in two of the posters (# 537 and # 546) are from phase 3, double-blind, placebo and active-controlled studies (Study 1 and Study 2) that randomized more than 2,400 patients to 14 days of twice-daily treatment with Ryaltris or placebo. Both studies assessed average change from baseline, in morning and evening, reflective Total Nasal Symptom Score (rTNSS) versus active comparators and placebo as the primary endpoint. Onset of action versus placebo was assessed using instantaneous Total Nasal Symptom Score (iTNSS) from 15 minutes through four hours post-first dose. Improvement in ocular symptoms, assessed as mean 
change in reflective Total Ocular Symptom Score (rTOSS) from baseline to study end, was also assessed.

A rapid onset of action with Ryaltris was observed, with an effect seen at 15 minutes post-dose versus placebo in Study 1 (p=0.013) and Study 2 (p=0.028), which was maintained at each subsequent time point assessed. In both studies, Ryaltris also improved rTOSS versus placebo (p=0.001). Treatment emergent adverse events (TEAEs) were low and comparable across treatments. The most frequent adverse events (AEs) reported with Ryaltris included decreased taste sensitivity (Study 1: Ryaltris 3.3%, placebo 0.7%; Study 2: Ryaltris 3.8%, placebo 0.0%) and headache (Study 1: Ryaltris 0.7%, placebo 2.8%; Study 2: Ryaltris 0.0%, placebo 0.7%).

Ryaltris resulted in statistically significant and clinically meaningful improvements in the primary efficacy endpoint of nasal symptom scores compared to placebo in Study 1, which was sustained for the entire treatment duration. (Poster # 546)

“Results of these robust studies demonstrates that consistent, significant relief from symptoms may be rapidly achieved and sustained with Ryaltris,” said Frank Hampel, Principal Investigator, Central Texas Health Research. “These findings, combined with prior studies demonstrating the long-term effects of Ryaltris on patient-reported outcomes, present a promising profile for a potential new treatment for SAR.”

Data were also presented from a double-blind, phase 2, proof-of-concept study that randomized 180 patients to 14 days of treatment with Ryaltris twice-daily or once-daily versus twice-daily azelastine/fluticasone*, olopatadine hydrochloride* or placebo in a ragweed pollen Environmental Exposure Chamber. The study assessed mean change in iTNSS as the primary endpoint. Onset of action was assessed by average change from baseline in iTNSS at time points from five minutes to four hours post-dose versus placebo. Ocular symptoms were also assessed using instantaneous Total Ocular Symptom Score (iTOSS). Onset of action with twice-daily Ryaltris versus placebo was observed at 10 minutes after the first dose (p=0.019) and was maintained at later time points except at 2.5 hours (p=0.06). Onset of action could not be defined for Ryaltris dosed once-daily. Ryaltris also improved symptoms in iTOSS compared to placebo (once-daily p=0.015, twice-daily p=0.001). The percentage of patients reporting TEAEs was comparable between treatments.

Headache (Ryaltris 11.1%, placebo 8.3%) and decreased taste sensitivity (Ryaltris 5.6%, placebo 0.0%) were the most common Aes reported among patients taking Ryaltris twice-daily.
