Sonoran Biosciences is a preclinical stage pharmaceutical company that has developed SB Gel, a novel viscous sustained release carrier. SB Gel enables sustained release of a wide variety of drugs to new sites in the body, including irregular surgical sites and device surfaces. We develop new formulations using approved active ingredients, requiring reduced development cost and risk while retaining the exclusivity of a typical pharmaceutical. Formulations based on SB Gel have potential in a number of therapeutic areas including infection and pain management. Our lead product, SBG002, is a fixed-dose combination of tobramycin and vancomycin being developed for treatment of prosthetic joint infection in a one-stage surgical approach.

Prosthetic joint infection (PJI) is a devastating complication of total joint replacement. PJI treatment requires multiple invasive surgeries staged months apart followed by a long recovery process and uncertain outcomes. Even when treated successfully, PJI can permanently alter a patient's life.

 

Likewise, the costs of PJI treatment are massive. There were nearly 50,000 PJIs treated in the US in 2014. With treatment of a single PJI imposing total costs of $100,000 or more, this represents a multi-billion dollar and growing burden on the healthcare system in the US alone. New reimbursement structures such as Accountable Care Organizations and bundled payments, shift the costs of managing infection to hospitals, strongly motivating providers to seek higher value treatments.

 

Despite urgent need, the current pipeline of new technologies to address PJI is virtually empty. Currently available products only facilitate the already expensive multi-surgery approach for the surgeon, and are often eschewed for a crude process involving hand-mixing of antibiotic powder into bone cement "off-label".

 

We are seeking not merely to facilitate treatment, but to enable an advancement in the standard of care for PJI: reliable treatment in a single surgery. Our lead product, SBG002, is designed to provide high and sustained antibiotic concentrations around the infected site which are sufficient to kill any remaining biofilm bacteria while being compatible with permanent reconstruction of the joint.
