Tonix Pharmaceuticals Holding Corp (NASDAQ:TNXP) fell sharply in Monday trading, having highlighted interim analysis of Phase 3 RALLY study of TNX-102 SL for the management of fibromyalgia.
The company, based in Chatham, New Jersey, said it had decided to stop enrollment in the Phase 3 RALLY study of TNX-102 SL (cyclobenzaprine HCl sublingual tablets) 5.6 mg for the management of fibromyalgia following an unblinded, pre-planned interim analysis by the Independent Data Monitoring Committee (IDMC) of the RALLY study.
Based on interim analysis results of the first 50% (n=337) enrolled participants, the IDMC recommended stopping the trial for futility as TNX-102 SL is unlikely to demonstrate a statistically significant improvement in the primary endpoint of overall change from baseline in daily diary pain severity scores between those treated with TNX-102 SL 5.6 mg (2x 2.8 mg tablets) and those receiving placebo.
Tonix remains blinded to the detailed interim analysis results and only received the recommendation made by the IDMC. Preliminary blinded safety data from these participants did not reveal any new safety signals, and the decision to discontinue enrolling new participants is not related to safety.
The Company intends to continue studying those participants currently enrolled until completion and then proceed with a full analysis of the unblinded data, with the topline results expected to be reported in the fourth quarter of 2021, to determine the next steps in this program.
TNXP shares tumbled 25 cents, or 25%, to 73 cents.
