About RBP-6000

RBP-6000 IS AN INVESTIGATIONAL PRODUCT THAT HAS NOT BEEN APPROVED BY THE U.S. FOOD AND DRUG ADMINISTRATION OR ANY OTHER REGULATORY AGENCY FOR SAFETY AND EFFICACY.

RBP-6000 is an investigational buprenorphine sustained-release formulation using our ATRIGEL® delivery system, which consists of a polymeric solution of a biodegradable poly-(DL-lactide-co-glycolide) co-polymer dissolved in N-methyl pyrrolidone (NMP), a water-miscible biocompatible solvent. After subcutaneous injection, NMP diffuses out of the polymer matrix and the polymer precipitates, trapping the drug inside and forming an amorphous solid depot in situ. The depot releases buprenorphine over a one-month period by diffusion as the polymer biodegrades.

Available safety findings suggest that 2.7% of subjects on RBP-6000 (both dosage regimens combined) experienced a serious treatment-emergent adverse event (TEAE) compared with 5.0% of subjects on placebo. There were no related serious TEAEs across groups. 6.9% of subjects on RBP-6000 (both dosage regimens combined) experienced a severe TEAE compared with 4.0% of subjects on placebo. 4.2 % of subjects on RBP-6000 (both dosage regimens combined) discontinued treatment due to TEAEs compared with 2.0% of subjects on placebo. The most common (reported in ≥ 5% of subjects) TEAEs reported in the active total group were headache, constipation, nausea, injection site pruritus, vomiting, insomnia and upper respiratory tract infection.
