Regulatory Development of ND0701 in the EU to Proceed Based on PK Similarity for the Treatment of Parkinson’s Disease
Trial 101 was a pilot crossover, randomized, two-sequence, 12-hour study with 18 healthy volunteers. The primary objective was to evaluate the PK and relative bioavailability of sub-cutaneous infusion of ND0701 and commercial apomorphine. No formal power analysis was performed for this study.
Plasma PK measures of ND0701 were comparable to the reference drug. These results support the continuation of ND0701’s development path to demonstrate its therapeutic equivalence to the reference drug. ND0701 did not raise safety and tolerability concerns, and exhibited a slightly better safety profile than that of the reference drug.
ND0701 contains apomorphine, the most potent dopamine agonist. Apomorphine, administered subcutaneously, is the most effective drug for the symptomatic treatment of Parkinson's disease after levodopa. Apomorphine is approved both in the United States and in the EU for acute administration as rescue treatment for off periods in Parkinson's disease (currently administered subcutaneously as bolus injections) and only in the EU and not in the United States for continuous, subcutaneously delivered chronic therapy of advanced Parkinson's patients. Current commercial apomorphine formulations, based on apomorphine-HCl, are associated with low tolerability and local pain and require daily subcutaneous administration of large volumes that limit its more widespread adoption. ND0701 is being developed as a chronic therapy of Parkinson's disease by continuous subcutaneous apomorphine administration. Based on a proprietary formulation of apomorphine-base, ND0701 is up to five times more concentrated than currently available commercial apomorphine-HCl products and should enable delivery through a small, low-volume, disposable patch-pump. In pre-clinical studies, ND0701 was also shown to have better local tolerability in pre-clinical studies than a leading commercial apomorphine product. ND0701 is designed to offer superior convenience and better tolerability to current, continuous, subcutaneously administered apomorphine-HCl products.
Parkinson's disease is a progressive neurodegenerative illness characterized by reduced dopamine in the brain, resulting in a debilitating decrease in the patient's motor and non-motor functions. Its symptoms, such as trembling in the extremities and face, slowness of movement and impaired balance and coordination, worsen over time and gravely impact the patient's quality of life. It has been shown that continuous administration of dopaminergic therapies, levodopa or apomorphine, can effectively treat motor fluctuations in Parkinson's disease patients without increasing troublesome dyskinesia.
NeuroDerm is a clinical-stage pharmaceutical Company developing central nervous system (CNS) product candidates that are designed to overcome major deficiencies of current treatments and achieve enhanced clinical efficacy through continuous, controlled administration. The Company has three product candidates in different stages of development which offer a solution for almost every Parkinson’s disease patient from the moderate to the very severe stage of the disease. The Company has developed a line of levodopa and carbidopa (LD/CD) product candidates administered through small belt pumps that deliver a continuous, controlled dose of LD/CD. The LD/CD product candidates are ND0612L and ND0612H, which are used for treatment of moderate and advanced Parkinson’s disease patients, respectively, and which are delivered subcutaneously. In addition, NeuroDerm is developing ND0701, a novel subcutaneously delivered apomorphine formulation for patients who suffer from moderate to severe Parkinson’s disease and who do not respond well to LD/CD. NeuroDerm is headquartered in the Weizmann Science Park in Rehovot, Israel.
