Aardvark Reports Exploratory ARD-101 Data; FDA Lifts Clinical Hold
Aardvark reported exploratory data from the ARD-101 trial, showing reductions in hyperphagia scores. The FDA lifted the clinical hold on ARD-101, and the company plans to seek FDA input on a new Phase 3 trial, expecting to resume clinical activities in 2027. The trial showed modest efficacy and was generally well tolerated.
