standard bupivacaine-based local analgesia infiltration, each as part of a standard multi-modal analgesic protocol. Patients were randomized to receive local infiltration analgesia with EXPAREL admixed with bupivacaine and expanded in volume to local infiltration analgesia with bupivacaine expanded in volume. The trial met its co-primary endpoints for postsurgical pain (p=0.0381) and opioid reduction (p=0.0048). We plan to report the statistical results for certain key secondary endpoints from this study in the first quarter of 2017. The full results will be submitted for publication in a peer-reviewed medical journal.
We are advancing a Phase 4 multicenter, randomized, double-blind, controlled trial of EXPAREL for postsurgical pain management in patients undergoing open lumbar spinal fusion surgery. Patients will be randomized to receive local infiltration analgesia with EXPAREL admixed with bupivacaine and expanded in volume or local infiltration analgesia with bupivacaine expanded in volume. The primary objective of this trial is to compare postsurgical pain control and the secondary objectives will compare additional efficacy, safety and health economic outcomes. We expect to report top-line data from this trial in the second half of 2017.
Soft Tissue Trials
In 2017, we plan to initiate a series of Phase 4 trials in soft tissue procedures with EXPAREL as part of an Enhanced Recover After Surgery, or ERAS, protocol. These will include a C-Section trial with a two-point TAP, a colorectal trial evaluating a four-point TAP and a unilateral breast reconstruction trial. These trials will evaluate opioid use and postsurgical pain control, as well as a number of additional efficacy, safety and health economic outcomes.
DepoCyt(e) is a sustained-release liposomal formulation of the chemotherapeutic agent cytarabine utilizing our DepoFoam technology. DepoCyt(e) is indicated for the intrathecal treatment of lymphomatous meningitis, a life-threatening complication of lymphoma, a cancer of the immune system. Lymphomatous meningitis can be controlled with conventional cytarabine, but because of the drug’s short half-life, a spinal injection is required twice per week, whereas DepoCyt(e) is dosed once every two weeks in an outpatient setting. DepoCyt(e) was granted accelerated approval by the FDA in 1999 and full approval in 2007. We recognized revenue from DepoCyt(e) of $7.2 million from our commercial partners in 2016.
DepoFoam—Our Proprietary Drug Delivery Technology
Our current product development activities utilize our proprietary DepoFoam drug delivery technology. DepoFoam consists of microscopic spherical particles composed of a honeycomb-like structure of numerous internal aqueous chambers containing an active drug ingredient. Each chamber is separated from adjacent chambers by lipid membranes. Following injection, the DepoFoam particles release drug over an extended period of time by erosion and/or reorganization of the particles’ lipid membranes. Release rates are determined by the choice and relative amounts of lipids in the formulation.
We believe the DepoFoam formulation provides several technical, regulatory and commercial advantages over competitive technologies, including:
