Our drug development pipeline currently includes four active programs in clinical or preclinical development stages. All of our drug candidates are small molecules designed for oral delivery.

Vyvanse™ (lisdexamfetamine dimesylate, formerly NRP104) is under FDA review for the treatment of ADHD in pediatric populations.

We are developing NRP290 to treat acute pain as an alternative to Lortab®, Vicodin® and Vicoprofen®. NRP290 is intended to be a safer, abuse-resistant and effective alternative to currently marketed opioids. NRP409 is being developed as a replacement or supplemental therapy in patients with primary hypothyroidism and other indications.

NRP369 has been repositioned as a backup to NRP290.
