NeuroDerm Ltd. (NASDAQ: NDRM), a clinical-stage pharmaceutical company developing drugs for central nervous system (CNS) diseases, today announced that continuous, subcutaneous delivery of the company’s proprietary liquid levodopa/carbidopa (LD/CD) product candidates, ND0612H and ND0612L, led to clinically-significant plasma levodopa levels. These results suggest that the high dose version, ND0612H, intended for severe Parkinson’s disease patients, may provide an effective therapy alternative to current treatments requiring surgery.
