AbbVie Announces High Sustained Virologic Response Rates in Phase 2 Studies with Pan-genotypic, Investigational Regimen in Patients with Chronic Hepatitis C

- Investigational HCV regimen with ABT-493 and ABT-530 evaluating a pan-genotypic, once-daily treatment option with shorter duration of therapy

- Late-breaking data demonstrate 97 percent SVR(12) in genotype 1 non-cirrhotic chronic hepatitis C patients after 8 weeks of treatment with ABT-493 and ABT-530

- First patient enrolled in Phase 3 trials

NORTH CHICAGO, Illinois, Nov. 16, 2015 /PRNewswire/ -- AbbVie (NYSE: ABBV), a global biopharmaceutical company, today announced data from the SURVEYOR studies of its investigational HCV regimen, ABT-493, an NS3/4A protease inhibitor, and ABT-530, an NS5A inhibitor, that show high rates of sustained virologic response at 12 weeks post-treatment (SVR₁₂) in non-cirrhotic patients with chronic hepatitis C virus (HCV) infection. After 12 weeks of treatment, SVR₁₂ rates achieved were 97-100 percent in genotype 1 (GT1), 96-100 percent in genotype 2 (GT2) and 83-94 percent in genotype 3 (GT3) patients.^1,2,3 These data are being presented at The Liver Meeting^® 2015, the Annual Meeting of the American Association for the Study of Liver Diseases (AASLD) in San Francisco.

Separately, in a late-breaking presentation of the SURVEYOR-I study, data show non-cirrhotic GT1 chronic HCV patients who received a shorter duration of treatment for 8 weeks with ABT-493 and ABT-530 achieved a SVR₁₂ rate of 97 percent.⁴

"These results are encouraging and contribute to scientific knowledge about the potential for pan-genotypic options for treating chronic hepatitis C," said Fred Poordad, M.D., vice president of Academic and Clinical Affairs at The Texas Liver Institute in San Antonio. "These data mark another important step in the continued research to help address the unmet needs of patients and the medical community."

SURVEYOR-I and SURVEYOR-II are ongoing Phase 2 clinical studies that evaluate the safety and efficacy of ABT-493 and ABT-530, with or without ribavirin (RBV), for 8 to 12 weeks. These data presented at AASLD include non-cirrhotic patients with GT1, GT2 and GT3 chronic HCV infection. Data in additional patient populations (genotypes 4-6) will be presented at future meetings.

"The SURVEYOR trials offer important new information about the potential to treat patients with chronic hepatitis C across multiple genotypes with our two direct-acting antiviral investigational regimen," said Michael Severino, M.D., executive vice president, research and development and chief scientific officer, AbbVie. "AbbVie's ongoing hepatitis C research program demonstrates our commitment to make a remarkable impact on the lives of HCV patients."

About SURVEYOR-I
SURVEYOR-I is an ongoing Phase 2 two-part study designed to evaluate the safety and efficacy of ABT-493 and ABT-530, with and without ribavirin (RBV), for 8 to 12 weeks, in cirrhotic and non-cirrhotic adult genotype 1 (GT1) patients, and non-cirrhotic adult patients with genotypes 4, 5 or 6 chronic HCV infection who were new to therapy or did not respond to previous treatment with pegylated interferon (pegIFN)/RBV (null responder).^1,4

In Part 1 of SURVEYOR-I, with 12 weeks of treatment, no patients discontinued treatment due to severe adverse events. The most commonly-reported direct-acting antiviral related adverse reactions (>10 percent of patients) were fatigue, headache and nausea. One patient experienced a serious adverse event of metastatic prostate cancer, unrelated to the study drugs and had onset after completion of study treatment.¹ In Part 2, with 8 weeks of treatment, there were no study-related serious or severe adverse events reported. One subject discontinued the study at treatment week 4 due to adenocarcinoma, unrelated to study drugs. The most frequent adverse event (>10 percent of patients) was fatigue.⁴

About SURVEYOR-II
SURVEYOR-II is an ongoing Phase 2 three-part study designed to evaluate the safety and efficacy of ABT-493 and ABT-530, with or without ribavirin (RBV), in cirrhotic and non-cirrhotic adult patients with genotype 2 (GT2) or genotype 3 (GT3) chronic HCV infection who were new to therapy or had failed previous treatment with pegIFN/RBV.^2,3 In GT2 study patients, the most commonly-reported direct-acting antiviral (DAA)-related adverse reactions (>10 percent of patients) were fatigue, nausea, diarrhea and headache. No GT2 study patients discontinued treatment due to an adverse event; one patient experienced a serious adverse event of atrial fibrillation unrelated to the study drugs.² In GT3 study patients, the most commonly-reported DAA-related adverse reactions (>10 percent of patients) were fatigue, nausea and headache. One patient discontinued treatment due to DAA- and RBV-related adverse events of abdominal pain and heat sensation. Two patients experienced a serious adverse event, one with pneumonia and one with B-cell lymphoma, both unrelated to the study drugs.³ Part 1 results of the SURVEYOR-II are presented at AASLD.

About AbbVie's HCV Clinical Development Program
AbbVie's HCV clinical development program is intended to advance scientific knowledge and the clinical care of people with chronic HCV infection by investigating pan-genotypic (genotypes 1-6), all-oral, ribavirin-free, once-daily treatment options including shorter (8-12 weeks) duration therapy. AbbVie's investigational regimen includes ABT-493, an NS3/4A protease inhibitor, and ABT-530, an NS5A inhibitor. ABT-493 and ABT-530 are currently being evaluated in Phase 2 studies with a multinational Phase 3 program in genotypes 1 through 6 initiated in November 2015.

ABT-493 was discovered during the ongoing collaboration between AbbVie and Enanta Pharmaceuticals (NASDAQ: ENTA) for HCV protease inhibitors and regimens that include protease inhibitors. ABT-493 is being developed by AbbVie for use in combination with AbbVie's other investigational medicines for the treatment of hepatitis C.
