On May 5, 2025, PTC issued a press release “announc[ing] results from the Phase 2 PIVOT-HD study of PTC518 (votoplam) in Stage 2 and Stage 3 Huntington’s disease (HD) patients.”  Although “[t]he study met its primary endpoint of reduction in blood Huntingtin (HTT) protein levels (p<0.0001) at Week 12 and favorable safety and tolerability”, analysts who reviewed the data anticipated that the Company would likely need to conduct a Phase 3 study to better establish whether the treatment is actually slowing HD. 

On this news, PTC’s stock price fell $9.30 per share, or 18.62%, to close at $40.65 per share on May 5, 2025.
