Samsung Bioepis' SB4 and SB2 Investigational Biosimilar Candidates Sustain Comparable Safety Profiles in One-Year Phase 3 Clinical Studies

- Positive one-year results show SB4 etanercept and SB2 infliximab investigational biosimilar candidates sustained comparable safety profiles observed in previously announced primary results

Ÿ- 24-week results for SB5 adalimumab investigational biosimilar candidate demonstrate equivalent efficacy and comparable safety to Humira®

Ÿ- SB4, SB2 and SB5 study results to be presented at 2015 ACR/ARHP Annual Meeting

INCHEON, Korea, Nov. 7, 2015 /PRNewswire/ -- Samsung Bioepis Co., Ltd. announced that SB4 etanercept and SB2 infliximab investigational biosimilar candidates sustained comparable safety profiles in 52- and 54-week clinical studies, respectively. Equally important, SB5 adalimumab investigational biosimilar candidate demonstrated both equivalent efficacy and comparable safety in a 24-week Phase 3 clinical study.

The latest Phase 3 results for SB4, SB2 and SB5 will be presented at the upcoming 2015 Annual Meeting of the American College of Rheumatology (ACR) and the Association for Rheumatology Health Professionals (ARHP) in San Francisco.

"The one-year clinical studies for SB4 and SB2 investigational biosimilar candidates provide encouraging indications of their comparable safety profiles," said Christopher Hansung Ko, CEO of Samsung Bioepis. "We will continue to focus on developing affordable biologic treatment options for patients who need these life-enhancing medications."

The 52-week SB4 study, which randomized 596 patients across 70 sites in 10 countries, showed ACR20 response rate of 80.8% in the SB4 arm versus 81.5% in the Enbrel^® arm, fully supporting the 24-week study results of 78.1% and 80.3%, respectively.

The 54-week SB2 study, which randomized 584 patients across 73 sites in 11 countries, showed ACR20 response rate of 65.3% in the SB2 arm versus 69.2% in the Remicade^® arm, fully supporting the 30-week study results of 64.1% and 66.0%, respectively.

The 24-week Phase 3 study of SB5, which randomized 544 patients with moderate to severe rheumatoid arthritis despite methotrexate therapy, showed ACR20 response rate of 72.5% in the SB5 arm versus 72.0% in the Humira^® arm. The safety profile of SB5 was comparable to Humira^®.

The 2015 ACR/ARHP Annual Meeting will be held between November 6-11, 2015 at the Moscone Center in San Francisco. The following data presentations are part of the official ACR program. Abstracts are available online through the ACR website at www.acrannualmeeting.org:
