ENLIGHTEN 1 trial did not meet its primary endpoint
Company plans to evaluate full dataset and path forward
WATERTOWN, Mass., May 06, 2024 (GLOBE NEWSWIRE) -- Lyra Therapeutics, Inc. (NASDAQ:LYRA) ("Lyra" or the "Company"), today announced topline results from the Company's Phase 3 ENLIGHTEN 1 trial evaluating LYR-210 for the treatment of chronic rhinosinusitis (CRS). ENLIGHTEN 1 did not meet its primary endpoint of demonstrating statistically significant improvement compared to sham control in the composite score of the three cardinal symptoms (3CS) of CRS (nasal obstruction, nasal discharge, facial pain/pressure) at 24 weeks. ENLIGHTEN 1 is one of two Phase 3 clinical trials evaluating LYR-210, a bioabsorbable sinonasal implant (7500µg mometasone furoate), as a six-month treatment for chronic rhinosinusitis (CRS).
"We are surprised and disappointed by the ENLIGHTEN 1 topline results," said Maria Palasis, Ph.D., President and Chief Executive Officer, Lyra Therapeutics. "We are moving as quickly as possible to evaluate the full dataset to better understand these findings in order to determine our path forward."
At 24 weeks, the ENLIGHTEN 1 trial demonstrated the following results compared to baseline, which did not achieve statistical significance:
LYR-210 was generally well tolerated, with no product-related serious adverse events. The most commonly reported adverse events in the study population were epistaxis, nasal odor, upper respiratory tract infection and sinusitis.
The ENLIGHTEN 1 trial is ongoing and data from the 52-week extension phase are expected in Q4 2024. ENLIGHTEN 2, the second pivotal Phase 3 trial of LYR-210 in CRS, is ongoing.
The Company expects to make near-term changes to its business operations and to reduce its workforce in order to preserve cash.
About the ENLIGHTEN 1 Trial
ENLIGHTEN 1 is a randomized, blinded, sham-controlled trial designed to evaluate the efficacy and safety of LYR-210 in patients with chronic rhinosinusitis (CRS) who have failed medical management and have not had prior ethmoid sinus surgery, randomized 2:1 to either LYR-210 or sham control for 24 weeks. At the end of the treatment phase, patients in the control group receive crossover LYR-210 treatment while patients in the LYR-210 group are re-randomized 1:1 to either receive a crossover sham-procedure or a repeat treatment with LYR-210 (7500 µg mometasone furoate); all patients are then followed through 52 weeks.
ENLIGHTEN 1 enrolled a total of 190 patients, approximately two-thirds from U.S. sites and one-third from sites in Europe. The mean baseline 3CS scores were 6.9 points and 6.7 points for treatment and sham control arms, respectively, and the mean SNOT-22 scores were 61 points in both the treatment and sham control arms. The baseline CT opacification scores were 44.9% and 47.3% for the treatment and sham control arms, respectively.
About LYR-210
LYR-210 is an investigational product candidate for the treatment of chronic rhinosinusitis (CRS) for up to four million CRS patients in the U.S. who fail current therapies annually and require further intervention. LYR-210 is a bioabsorbable sinonasal implant that is designed to deliver six months of continuous anti-inflammatory medication (7500µg mometasone furoate) to the sinonasal passages for the treatment of CRS. CRS is a highly prevalent inflammatory disease of the paranasal sinuses which leads to debilitating symptoms and significant morbidities and is the fifth most common condition in people under age 65.
