Bristol-Myers Squibb to Present New Data Demonstrating Company's Leadership in Liver Disease at The Liver Meeting? / AASLD Annual Meeting

Bristol-Myers Squibb Company (NYSE: BMY) announced today that 22 abstracts on the Company's research in liver disease have been accepted for presentation at The Liver Meeting^® 2011, the 62^nd annual meeting of the American Association for the Study of Liver Diseases (AASLD), in San Francisco, November 4 - 8. Bristol-Myers Squibb is advancing a portfolio of compounds that has the potential to address unmet medical needs for patients with liver disease, including BARACLUDE^® (entecavir) for chronic hepatitis B (CHB), and the investigational compounds BMS-790052, BMS-650032 and PEG-Interferon lambda (Lambda) for hepatitis C (HCV) and brivanib for hepatocellular carcinoma (HCC).

Key presentations include an oral presentation on BARACLUDE monotherapy vs. combination therapy for CHB and two oral presentations of Phase II data on the Company's investigational HCV direct-acting antivirals (DAAs). These presentations will highlight:

• The first data from the BE-LOW study, a Phase IIIb comparative study of BARACLUDE plus tenofovir vs. BARACLUDE monotherapy in treatment-naïve adults with CHB
• The first results from a Phase IIb study of the NS5A replication complex inhibitor BMS-790052 plus peginterferon alfa and ribavirin (alfa/RBV) in treatment-naive HCV genotype 1 and 4 patients, evaluating virologic response through 12 weeks on treatment (eRVR)
• The first results of a Phase IIa study of the dual DAA regimen of BMS-790052 and the NS3 protease inhibitor BMS-650032 in HCV genotype 1b-infected patients who have not responded to prior alfa/RBV therapy (null responders), evaluating sustained virologic response 12 weeks post-treatment (SVR12)

"Bristol-Myers Squibb is at the forefront of innovation in researching the treatment of liver diseases. In hepatitis C, where there remain considerable unmet medical needs, our goal is to increase treatment options for patients by developing a portfolio of compounds with different mechanisms of action," said Brian Daniels, MD, senior vice president, Global Development and Medical Affairs, Research and Development, Bristol-Myers Squibb. "The data we are presenting at the Liver Meeting help to expand our understanding of the potential efficacy and safety profiles of these investigational compounds and support the recent initiation of a broad Phase III development program in HCV."

The Company will also present new data that further describe the mechanistic and clinical profile of Lambda, and real-world data that add to the understanding of the prevalence of and current treatment patterns in HBV, HCV and HCC, including an oral presentation of data from the BRIDGE study in HCC. The BRIDGE study is designed to develop global understanding of HCC, including assessment of treatment by geography and etiology, and associated clinical outcomes.

The complete list of Bristol-Myers Squibb data presentations is below. Abstracts can be accessed on the AASLD website at http://aasld2011.abstractcentral.com/login.

INDICATION and IMPORTANT SAFETY INFORMATION about BARACLUDE^® (entecavir)

INDICATION

BARACLUDE is indicated for the treatment of chronic hepatitis B virus (HBV) infection in adults with evidence of active viral replication and either evidence of persistent elevations in serum aminotransferases (ALT or AST) or histologically active disease.

The following points should be considered when initiating BARACLUDE:

• This indication is based on histologic, virologic, biochemical, and serologic responses in nucleoside-treatment-naïve and lamivudine-resistant adult subjects with HBeAg-positive or HBeAg-negative chronic HBV infection and compensated liver disease.
• Virologic, biochemical, serologic, and safety data are available from a controlled study in adult subjects with chronic HBV infection and decompensated liver disease.
• Virologic, biochemical, serologic, and safety data are available for a limited number of adult subjects with HIV/HBV co-infection who have received prior lamivudine therapy.

IMPORTANT SAFETY INFORMATION

WARNINGS: SEVERE ACUTE EXACERBATIONS OF HEPATITIS B, PATIENTS CO-INFECTED WITH HIV AND HBV, and LACTIC ACIDOSIS AND HEPATOMEGALY

• Severe acute exacerbations of hepatitis B have been reported in patients who have discontinued anti-hepatitis B therapy, including entecavir. Hepatic function should be monitored closely with both clinical and laboratory follow-up for at least several months in patients who discontinue anti-hepatitis B therapy. If appropriate, initiation of anti-hepatitis B therapy may be warranted.
• Limited clinical experience suggests there is a potential for the development of resistance to HIV (human immunodeficiency virus) nucleoside reverse transcriptase inhibitors if BARACLUDE is used to treat chronic HBV infection in patients with HIV infection that is not being treated. Therapy with BARACLUDE is not recommended for HIV/HBV co-infected patients who are not also receiving highly active antiretroviral therapy (HAART).
• Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with the use of nucleoside analogues, alone or in combination with antiretrovirals.

Warnings and Precautions

• Before initiating BARACLUDE therapy, HIV antibody testing should be offered to all patients. BARACLUDE has not been studied as a treatment for HIV infection and is not recommended for this use.
• Lactic acidosis with BARACLUDE use has been reported, often in association with hepatic decompensation, other serious medical conditions, or drug exposures. Patients with decompensated liver disease may be at higher risk for lactic acidosis. BARACLUDE should be suspended in any patient who develops clinical or laboratory findings suggestive of lactic acidosis or pronounced hepatotoxicity.

Adverse Reactions

• In clinical trials in patients with compensated liver disease, the most common (=3%) adverse reactions of any severity with at least a possible relation to study drug for BARACLUDE-treated subjects were headache, fatigue, dizziness, and nausea. In these trials, the most common adverse reactions of moderate to severe intensity (grades 2-4) were diarrhea, dyspepsia, nausea, vomiting, fatigue, headache, dizziness, somnolence, and insomnia.
• In the decompensated liver disease trial, the most common adverse reactions of any severity among patients treated with BARACLUDE, regardless of causality, included: peripheral edema (16%), ascites (15%), pyrexia (14%), hepatic encephalopathy (10%), and upper respiratory infection (10%). In this trial, 18% (18/102) of BARACLUDE patients and 20% (18/89) of adefovir patients died during the first 48 weeks of therapy. The majority of those deaths were due to liver related causes.

Drug Interactions

BARACLUDE is primarily eliminated by the kidneys, therefore coadministration of BARACLUDE with drugs that reduce renal function or compete for active tubular secretion may increase serum concentrations of either entecavir or the coadministered drug. Patients should be monitored closely when receiving BARACLUDE with other renally-eliminated drugs.

Pregnancy and Nursing Mothers

• There are no adequate and well-controlled studies of BARACLUDE in pregnant women. BARACLUDE should be used during pregnancy only if clearly needed and after careful consideration of the risks and benefits.
• There are no studies on the effect of BARACLUDE on transmission of HBV from mother to infant. Therefore, appropriate interventions should be used to prevent neonatal acquisition of HBV.
• It is not known whether BARACLUDE is excreted into human milk; however, many drugs are excreted into breast milk. Due to the potential for serious adverse reactions in nursing infants from BARACLUDE, risks and benefits should be considered when deciding whether to discontinue breast-feeding or discontinue BARACLUDE in nursing women.

Pediatric Use

• Safety and effectiveness of BARACLUDE in pediatric patients below the age of 16 years have not been established.

Renal Impairment

• Dosage adjustment of BARACLUDE is recommended for patients with a creatinine clearance 50 mL/min, including those on hemodialysis or continuous ambulatory peritoneal dialysis.
• The safety and efficacy of BARACLUDE in liver transplant recipients are unknown. Renal function must be carefully monitored both before and during treatment with BARACLUDE in a liver transplant recipient who has received or is receiving an immunosuppressant that may affect renal function, such as cyclosporine or tacrolimus.

Dosage and Administration

BARACLUDE should be administered on an empty stomach (at least 2 hours after a meal and at least 2 hours before the next meal).

The recommended dose of BARACLUDE:

• in nucleoside-naïve adults and adolescents (16+ yrs) with compensated liver disease is 0.5 mg once daily
• in adults and adolescents (16+ yrs) with compensated liver disease, and refractory to lamivudine or with known lamivudine or telbivudine resistance mutations (rtM204I/V with or without rtL180M, rtL80I/V, or rtV173L) is 1 mg once daily
• in adults with decompensated liver disease is 1 mg once daily

The optimal duration of treatment with BARACLUDE for patients with chronic HBV infection and the relationship between treatment and long-term outcomes such as cirrhosis and hepatocellular carcinoma are unknown.

Additional Information

Patients should be advised that treatment with BARACLUDE has not been shown to reduce the risk of transmission of HBV to others through sexual contact or blood contamination.
