(NASDAQ:SBPH), a clinical-stage biopharmaceutical company developing novel therapeutics for the treatment of viral infections, inflammatory diseases and certain cancers, today announced that a scientific abstract that includes additional data from the first cohort of the ongoing ACHIEVE clinical trial of SB 9200 will be presented at the 2017 International HBV Meeting on the Molecular Biology of Hepatitis B Viruses, to be held September 3-7, 2017 in Washington D.C. The abstract will be presented orally as part of a Satellite Symposium: “New HBV Antiviral and Immune Modulatory Therapies in Late Pre-Clinical/Clinical Development.”

The Satellite Symposium, organized by Dr. Anna S. Lok, University of Michigan, and Dr. Marc Ghany, NIH, is scheduled for Thursday, September 7th from 8:15 am – 12:30 pm EDT at the Marriott Waldman Hotel in Washington D.C.  The Satellite Symposium will provide an overview of gaps in knowledge of current and future HBV treatment, as well as a discussion on endpoints and designs of clinical trials aimed at HBV cure.

Abstract #112526: Phase IIa ACHIEVE Clinical Trial of SB 9200: Results from the Tenofovir Switch Segment of the 25mg Cohort, MF Yuen et al.

The ongoing ACHIEVE trial is a placebo-controlled phase 2 study of SB 9200 in HBV treatment-naïve patients. Each cohort receives 12 weeks of monotherapy with SB 9200 at doses of 25mg, 50mg, 100mg, 200mg or placebo and is then subsequently switched to tenofovir¹ 300mg (TDF) daily for 12 weeks (week 12 – 24).  Spring Bank previously reported top-line results showing that the low dose (25mg) of SB 9200 alone showed a favorable safety profile and antiviral activity against HBV DNA and HBsAg.  Administration of SB 9200 resulted in a statistically significant reduction in HBV DNA at week 12 (unpaired t-test 2.85, p=0.01) compared to placebo, with a mean reduction of 0.6 log₁₀ (range 0 to 1.87 log₁₀) in the SB 9200 treatment group.  Complete data on the full 25mg cohort after the switch to TDF will be presented at the Satellite Symposium.
