STOCKHOLM--(BUSINESS WIRE)--Regulatory News: Diamyd Medical AB (STO:DIAMB) (Pink Sheets: DMYDY) reports that a Phase II study evaluating the Company’s drug candidate NP2 Enkephalin did not meet its primary objective of reducing pain in subjects with severe intractable cancer pain. The treatment was however well tolerated, confirming the safety of the Company’s NTDDS technology. The purpose of the randomized, double-blind, and placebo-controlled Phase II study is to evaluate the effect of intradermal injection of NP2 Enkephalin on pain reported by subjects suffering from severe intractable pain due to cancer, as well as to confirm the safety of the treatment. The study includes a total of 33 adult subjects, 17 randomized to receive NP2 Enkephalin and 16 randomized to the placebo group. It is being conducted at 18 clinics in the United States. It is the first placebo-controlled clinical trial of a drug candidate based on Diamyd Medical’s patented Nerve Targeting Drug Delivery System (NTDDS), a gene based technology for delivery of therapeutics directly to the nervous system.
