Aspen raises a $140M IPO in pursuit of a cell therapy for Parkinson’s
Aspen Neuroscience raised $140.6M in its IPO, selling 9.4M shares at $15 each. The company's cell therapy, sasineprocel, aims to treat Parkinson's by replenishing dopamine-producing neurons. It will trade under 'ASPE'. Early trial data showed potential improvements and a favorable safety profile. Long-term data is expected in 2028, with a Phase 3 study planned by the end of 2024. Aspen claims its personalized approach could be safer and more effective than donor-derived therapies.
