U.S. Food and Drug Administration Accepts Supplemental Biologics License Application forOpdivo (nivolumab) in Patients with Previously Untreated Advanced Melanoma
Application includes CheckMate -066, a clinical trial of Opdivo vs. dacarbazine chemotherapy
in patients who had not received prior therapy
CheckMate -066 marked the first time that a PD-1 immune checkpoint inhibitor demonstrated
survival in a Phase III clinical trial(PRINCETON, NJ, April 29, 2015) – Bristol-Myers Squibb Company (NYSE: BMY) today
announced that the U.S. Food and Drug Administration (FDA) has accepted for filing and review thesupplemental Biologics License Application (sBLA) for Opdivo (nivolumab) for the treatment ofpreviously untreated patients with unresectable or metastatic melanoma. The FDA also granted Priority
Review for this application. The projected FDA action date is August 27, 2015.
Opdivo was first approved by the FDA in December 2014 for patients with unresectable ormetastatic melanoma and disease progression following Yervoy (ipilimumab) and, if BRAF V600
mutation positive, a BRAF inhibitor. This initial indication was approved under accelerated approval
based on tumor response rate and durability of response from CheckMate -037 clinical trial results. Thisnew sBLA accepted by the FDA includes data from CheckMate -066, which evaluated Opdivo intreatment naïve patients with BRAF wild-type advanced melanoma as compared to dacarbazine
chemotherapy (DTIC). In the trial, safety and tolerability were well-charactized with fewer treatmentrelated Grade 3/4 adverse events observed with Opdivo than dacarbazine.
“The CheckMate -066 trial marked the first time that a PD-1 immune checkpoint inhibitor
showed a survival benefit in a randomized Phase III trial,” said Michael Giordano, senior vice president,
Head of Development, Oncology, Bristol-Myers Squibb. “We look forward to continuing to work with
the FDA to ensure cancer patients are provided the latest clinical advances that have the potential for
improved responses and long-term survival.”

About Advanced Melanoma
Melanoma is a form of skin cancer characterized by the uncontrolled growth of pigmentproducing cells (melanocytes) located in the skin. Metastatic melanoma is the deadliest form of thedisease, and occurs when cancer spreads beyond the surface of the skin to the other organs, such as thelymph nodes, lungs, brain or other areas of the body. The incidence of melanoma has been increasing forat least 30 years. In 2015, an estimated 73,870 melanoma cases will be diagnosed in the U.S. Melanoma

is mostly curable when treated in its early stages. However, in its late stages, the average survival rate isjust 6 months with a 1-year survival of 25.5%, making it one of the most aggressive forms of cancer.
About Opdivo
Opdivo is a programmed death-1 (PD-1) immune checkpoint inhibitor that has received approval
from the U.S. FDA as a monotherapy in two cancer indications. On March 5, 2015, Opdivo received
FDA approval for the treatment of patients with metastatic squamous non-small cell lung cancer(NSCLC) with progression on or after platinum-based chemotherapy.
In the U.S., Opdivo is also indicated for the treatment of patients with unresectable or metastaticmelanoma and disease progression following Yervoy (ipilimumab) and, if BRAF V600 mutation positive,
a BRAF inhibitor. This indication is approved under accelerated approval based on tumor response rateand durability of response. Continued approval for this indication may be contingent upon verificationand description of clinical benefit in the confirmatory trials. Opdivo became the first PD-1 immune
checkpoint inhibitor to receive regulatory approval anywhere in the world on July 4, 2014 when Ono
Pharmaceutical Co. announced that it received manufacturing and marketing approval in Japan for thetreatment of patients with unresectable melanoma.
Bristol-Myers Squibb has a broad, global development program to study Opdivo in multiple
tumor types consisting of more than 50 trials – as monotherapy or in combination with other therapies –in which more than 7,000 patients have been enrolled worldwide.

Immuno-Oncology at Bristol-Myers Squibb
Surgery, radiation, cytotoxic or targeted therapies have represented the mainstay of cancer
treatment over the last several decades, but long-term survival and a positive quality of life haveremained elusive for many patients with advanced disease.
To address this unmet medical need, Bristol-Myers Squibb is leading research in an innovative
field of cancer research and treatment known as immuno-oncology, which involves agents whose
primary mechanism is to work directly with the body’s immune system to fight cancer. The company is
exploring a variety of compounds and immunotherapeutic approaches for patients with different types ofcancer, including researching the potential of combining immuno-oncology agents that target different
pathways in the treatment of cancer.
Bristol-Myers Squibb is committed to advancing the science of immuno-oncology, with the goalof changing survival expectations and the way patients live with cancer.

About the Bristol-Myers Squibb and Ono Pharmaceutical Collaboration
In 2011, through a collaboration agreement with Ono Pharmaceutical, Bristol-Myers Squibb
expanded its territorial rights to develop and commercialize Opdivo globally except in Japan, South
Korea and Taiwan, where Ono had retained all rights to the compound at the time. On July 23, 2014,
Bristol-Myers Squibb and Ono Pharmaceutical further expanded the companies’ strategic collaborationagreement to jointly develop and commercialize multiple immunotherapies – as single agents andcombination regimens – for patients with cancer in Japan, South Korea and Taiwan.

IMPORTANT SAFETY INFORMATION
Immune-Mediated Pneumonitis
Severe pneumonitis or interstitial lung disease, including fatal cases, occurred with OPDIVO
treatment. Across the clinical trial experience in 691 patients with solid tumors, fatal immunemediated pneumonitis occurred in 0.7% (5/691) of patients receiving OPDIVO; no cases
occurred in Trial 1. In Trial 1, pneumonitis, including interstitial lung disease, occurred in 3.4%(9/268) of patients receiving OPDIVO and none of the 102 patients receiving chemotherapy.
Immune-mediated pneumonitis occurred in 2.2% (6/268) of patients receiving OPDIVO; onewith Grade 3 and five with Grade 2. Monitor patients for signs and symptoms of pneumonitis.
Administer corticosteroids for Grade 2 or greater pneumonitis. Permanently discontinue
OPDIVO for Grade 3 or 4 and withhold OPDIVO until resolution for Grade 2.

Immune-Mediated Colitis
In Trial 1, diarrhea or colitis occurred in 21% (57/268) of patients receiving OPDIVO and 18%(18/102) of patients receiving chemotherapy. Immune-mediated colitis occurred in 2.2% (6/268)
of patients receiving OPDIVO; five with Grade 3 and one with Grade 2. Monitor patients for
immune-mediated colitis. Administer corticosteroids for Grade 2 (of more than 5 days duration),
3, or 4 colitis. Withhold OPDIVO for Grade 2 or 3. Permanently discontinue OPDIVO for Grade
4 colitis or recurrent colitis upon restarting OPDIVO.

Immune-Mediated Hepatitis
In Trial 1, there was an increased incidence of liver test abnormalities in the OPDIVO-treatedgroup as compared to the chemotherapy-treated group, with increases in AST (28% vs 12%),alkaline phosphatase (22% vs 13%), ALT (16% vs 5%), and total bilirubin (9% vs 0). Immunemediated hepatitis occurred in 1.1% (3/268) of patients receiving OPDIVO; two with Grade 3
and one with Grade 2. Monitor patients for abnormal liver tests prior to and periodically during
treatment. Administer corticosteroids for Grade 2 or greater transaminase elevations. Withhold
OPDIVO for Grade 2 and permanently discontinue OPDIVO for Grade 3 or 4 immune-mediatedhepatitis.

Immune-Mediated Nephritis and Renal DysfunctionIn Trial 1, there was an increased incidence of elevated creatinine in the OPDIVO-treated groupas compared to the chemotherapy-treated group (13% vs 9%). Grade 2 or 3 immune-mediatednephritis or renal dysfunction occurred in 0.7% (2/268) of patients. Monitor patients for elevatedserum creatinine prior to and periodically during treatment. For Grade 2 or 3 serum creatinine
elevation, withhold OPDIVO and administer corticosteroids; if worsening or no improvement
occurs, permanently discontinue OPDIVO. Administer corticosteroids for Grade 4 serum
creatinine elevation and permanently discontinue OPDIVO.

Immune-Mediated Hypothyroidism and Hyperthyroidism
In Trial 1, Grade 1 or 2 hypothyroidism occurred in 8% (21/268) of patients receiving OPDIVO
and none of the 102 patients receiving chemotherapy. Grade 1 or 2 hyperthyroidism occurred in
3% (8/268) of patients receiving OPDIVO and 1% (1/102) of patients receiving chemotherapy.
Monitor thyroid function prior to and periodically during treatment. Administer hormone
replacement therapy for hypothyroidism. Initiate medical management for control ofhyperthyroidism.

Other Immune-Mediated Adverse Reactions
The following clinically significant, immune-mediated adverse reactions occurred in less than
2% of OPDIVO-treated patients: adrenal insufficiency, uveitis, pancreatitis, facial and abducens
nerve paresis, demyelination, autoimmune neuropathy, motor dysfunction, and vasculitis. Acrossclinical trials of OPDIVO administered at doses 3 mg/kg and 10 mg/kg, additional clinicallysignificant, immune-mediated adverse reactions were identified: hypophysitis, diabetic
ketoacidosis, hypopituitarism, Guillain-Barré syndrome, and myasthenic syndrome. Based on
the severity of adverse reaction, withhold OPDIVO, administer high-dose corticosteroids, and, if
appropriate, initiate hormone- replacement therapy.

Embryofetal Toxicity


Based on its mechanism of action, OPDIVO can cause fetal harm when administered to apregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females ofreproductive potential to use effective contraception during treatment with OPDIVO and for atleast 5 months after the last dose of OPDIVO.

Lactation

It is not known whether OPDIVO is present in human milk. Because many drugs, including
antibodies, are excreted in human milk and because of the potential for serious adverse reactions
in nursing infants from OPDIVO, advise women to discontinue breastfeeding during treatment.

Serious Adverse Reactions
Serious adverse reactions occurred in 41% of patients receiving OPDIVO. Grade 3 and 4 adverse
reactions occurred in 42% of patients receiving OPDIVO. The most frequent Grade 3 and 4adverse drug reactions reported in 2% to <5% of patients receiving OPDIVO were abdominal
pain, hyponatremia, increased aspartate aminotransferase, and increased lipase.

Common Adverse Reactions

The most common adverse reaction (≥20%) reported with OPDIVO was rash (21%).
