About Opdivo
Opdivo (nivolumab) is a programmed death-1 (PD-1) immune checkpoint inhibitor that is designed to uniquely harness the body’s own immune system to help restore anti-tumor immune response. By harnessing the body’s own immune system to fight cancer, Opdivo has become an important treatment option across multiple cancers.

Opdivo’s leading global development program is based on Bristol-Myers Squibb’s scientific expertise in the field of Immuno-Oncology, and includes a broad range of clinical trials across all phases, including Phase 3, in a variety of tumor types. To date, the Opdivo clinical development program has enrolled more than 25,000 patients. The Opdivo trials have contributed to gaining a deeper understanding of the potential role of biomarkers in patient care, particularly regarding how patients may benefit from Opdivo across the continuum of PD-L1 expression.

Not for Promotional Purposes

In July 2014, Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world. Opdivo is currently approved in more than 65 countries, including the United States, the European Union, Japan and China. In October 2015, the Company’s Opdivo and Yervoy combination regimen was the first immuno-oncology combination to receive regulatory approval for the treatment of metastatic melanoma and is currently approved in more than 50 countries, including the United States and the European Union.

Bristol-Myers Squibb and Ono Pharmaceutical Co. jointly develop and market Opdivo, with Ono responsible for Japan, South Korea and Taiwan and Bristol-Myers Squibb responsible for the rest of the world.

About Empliciti

Empliciti (elotuzumab) is an immunostimulatory antibody that specifically targets Signaling Lymphocyte Activation Molecule Family member 7 (SLAMF7), a cell-surface glycoprotein. SLAMF7 is expressed on myeloma cells independent of cytogenetic abnormalities. SLAMF7 also is expressed on Natural Killer cells, plasma cells and at lower levels on specific immune cell subsets of differentiated cells within the hematopoietic lineage.

Not for Promotional Purposes

Empliciti has a dual mechanism-of-action. It directly activates the immune system through Natural Killer cells via the SLAMF7 pathway. Empliciti also targets SLAMF7 on myeloma cells, tagging these malignant cells for Natural Killer cell-mediated destruction via antibody-dependent cellular toxicity.

Empliciti was initially approved by the FDA in 2015 in combination with Revlimid (lenalidomide) and dexamethasone for the treatment of patients with multiple myeloma who have received one to three prior therapies.

Bristol-Myers Squibb and AbbVie are co-developing Empliciti, with Bristol-Myers Squibb solely responsible for commercial activities.

Eliquis 10 Million Patients and Counting

February 15, 2018

Cardiovascular diseases has long been an important therapeutic area for Bristol-Myers Squibb and our research and development efforts have led to a number of important treatment options for patients over the past decades.  Our priority product, Eliquis (apixaban), is the No. 1 prescribed oral anti-coagulant in the U.S. and the No. 1 prescribed novel oral anti-coagulant in the world.

Beyond outstanding sales performance, Eliquis is making a significant difference for millions of patients across the globe. Approximately 10 million patients have been treated with Eliquis since its launch in 2013. This means that 10 million people received a therapy that significantly reduced their risk of experiencing a stroke, pulmonary embolism or major bleeding compared with the historical standard of care. When we consider the efficacy and safety profile of Eliquis, we are incredibly proud of the work we do and the differentiated impact we are making on the lives of so many people across the globe.

This milestone is not reached without meaningful contributions from colleagues across the Bristol-Myers Squibb enterprise. To start, Eliquis was discovered and developed by BMS scientists. Colleagues in Medical and HEOR (Health Economics and Outcomes Research) have also played critical roles generating clinical trial and real-world data evidence. Additionally, the Global Product Development and Supply team built a robust manufacturing and supply operation to support the rapid growth of Eliquis; an operation that recently withstood a devastating hurricane in Puerto Rico with no interruption to global supply.

Last year, in recognition of their strong research advancements, a team of Bristol-Myers Squibb scientists received the prestigious 2018 Sir James Black award from the British Pharmacological Society for their contributions in the discovery of Eliquis.

Behind the Design of the Eliquis Starter Pack
Contributions of GPS Field Sales Force Help Make a Commercial-led Project a Reality
June 27, 2018

As the GPS Strategic Product Lead (SPL) for Eliquis at the time of the starter pack’s development, Fritz Lloyd was on point for delivering the GPS resources needed to make this Commercial-led project a reality.

There’s more to the job of the sales force than selling medicines, says Executive Institutional Territory Business Manager Chris van der Kieft, a member of the cardiovascular sales force whose clients include some of Boston’s major medical centers. Another responsibility is taking feedback from customers to make our products and services even better. And there’s more to the job of GPS than making medicines, says Fritz Lloyd, the GPS strategic product leader for Opdivo, and previously Eliquis. It’s also about providing ideas and solutions that help Commercial succeed.  The development of the first Eliquis Starter Pack for patients starting treatment for deep vein thrombosis (DVT) or pulmonary embolism (PE) proved them both right.

When a competitor was first to market with a starter pack for new DVT patients the BMS U.S. Eliquis VTE Professional Marketing Lead John Hidalgo was determined to make a better one.  “Listening to what our customers had to say was our first priority,” said Hidalgo.  Today, with the finished product now in doctors’ hands, van der Kieft said his customers couldn’t be happier with the results. “They know BMS is listening to what they’re saying,” he said.  “Their reaction is: ‘Thank you for helping us treat our patients.’”

“The result is a product that makes it simple for patients to follow the dosing, and gives comfort to doctors and hospitals that their patients have everything they need to start their treatment,” said U.S. Eliquis VTE Professional Marketing Lead John Hidalgo.

The Need

DVT is a blood clot in a deep vein that limits blood flow. Sometimes a clot breaks free and travels to the lungs to become a pulmonary embolism, which can be fatal. Doctors have traditionally prescribed warfarin for DVT/PE treatment, but the newer Direct-Acting Oral Anticoagulants (DOACs) such as Eliquis are gaining ground. Like Eliquis, Warfarin, also known by the brand name Coumadin, is a medicine in BMS’ established brands and part of Innovative Medicines.

For patients, starting treatment with a DOAC can be confusing. Dosing changes as the patient comes onto the treatment and that can sometimes present challenges to adherence.

DOAC patients also require less frequent follow-up testing. That’s one of their advantages, but it means fewer chances for physicians to ask if patients are taking their medicine compliantly. Furthermore, patients often get their first prescriptions at a hospital after a thrombotic event such as a blood clot. Shaken by that experience, they may not be in the best state to process the prescribing instructions.

Finally, hospital patients like these will typically get follow-up care from their cardiologist or primary care doctor.  The health care system in general and hospitals in particular are increasingly focused on how to better support patients through these “transitions of care.” Insights like these validated the marketing team’s market assessment on the need for a DVT/PE Eliquis starter pack and what it would take to succeed.

“Chris helped us confirm the need from the marketplace,” said U.S. Eliquis VTE Professional Marketing Lead John Hidalgo. “His insights validated the marketing team’s view that a starter pack would provide real benefits to patients, physicians and hospitals.”  With the need confirmed, it was time to execute.

Delivering for Patients

As the strategic product leader for Eliquis for Global Product Development and Supply (GPS), Lloyd was on point for delivering the manufacturing and supply resources needed to bring the project launched by Hidalgo and the market research, medical strategy, regulatory and marketing teams to the finish line. Given its complexity, GPS proved to be a key partner by providing ideas and solutions for overcoming a variety of challenges.

These included designing a box with two cartons or “wallets” in such a way that patients could easily understand which carton to use first. Designing for child-resistance was another challenge. The innovative solution was a design requiring a two-handed opening technique in which patients push the carton in one
location and pull the tablet out from another.

A final hurdle was building the machinery to mass-produce the starter pack. In this, Lloyd credited the GPS External Manufacturing team led by Sean O’Leary for its exceptional accountability and passion in working with BMS stakeholders, vendors and contract manufacturers.

“The team persevered through multiple design and production challenges to deliver this high priority product on time,” said Lloyd, GPS strategic product lead for Opdivo. “We set out and developed the starter pack having patients in mind,” said Hidalgo. “The result is a product that makes it simple for patients to follow the dosing, and gives comfort to doctors and hospitals that their patients have everything they need to start their treatment. It is truly a win-win for patients and providers.”

China Global Buddy Program Helps Accelerate Opdivo Approval

July 18, 2018

Xiaoqing Zhang, senior principal scientist and a PAN China chapter lead, and Summer Shi, regulatory coordination lead, talk with Chief Scientific Officer Tom Lynch about the effectiveness and the value of the PAN Buddy Program.

With the June 15 announcement that the China National Drug Administration (CNDA) has approved the first Immuno-Oncology agent, Opdivo, for the treatment of second-line non-small cell lung cancer (NSCLC), it seems that BMS China has beaten its global competitors to market.

Since 2015, significant achievements have been made by the health authority in China to accelerate approvals in prioritized areas, such as oncology, by encouraging innovation as quickly as possible. These significant achievements are enabling China to move faster – participating in global trials and accelerating timelines for Clinical Trial Applications (CTAs). In short: China is moving faster than ever, and Bristol-Myers Squibb (BMS) must move just as quickly to stay ahead of the competition in this important market.

Innovating to Accelerate Approvals

To do so, BMS’ PAN Asian Network (PAN) People Business and Resource Group (PBRG) and the China R&D organization launched the PAN China Global Buddy Program in October of 2017. The program is designed to address a dramatic increase in workload since BMS China’s integration in global development last year – now with 40 clinical studies to be initiated/completed in IO before the end of 2018 – and quickly onboard a talent pool with little global experience. In fact, limited local talent combined with high demand and a high turnover rate, between two to three years, were having a negative effect on BMS China.

According to Jing Yang, senior principal scientist and a PAN Tri-chair, the initiative is “just one more way that the PAN PRBG is helping to drive business results.”

The PAN Buddy Program is a four-week shadowing rotation for BMS China employees to visit a BMS facility in the United States.  The goal of the program is to provide role-specific training to facilitate the efficient integration of new hires into BMS; establish a global-China network and improve communications; establish a new industry standard with a PBRG promoting employee retention; and provide leadership development opportunities via PBRG, as the trainees become PAN site leads at the end of their training session.

Eligible China R&D trainees (~10 trainees per session; 2 sessions per year) are selected by BMS China function heads and are focused on employees who have at least six months with BMS China, and who regularly interact with leadership in an important role. Their buddies are U.S. R&D employees who work in functions relevant to the needs of the trainee. This program is designed to create long-term relationships so that buddies will continue to help their Chinese counterparts to navigate their way through the global teams after the face-to-face coaching is finished.

The PAN Buddy Program is a four-week shadowing rotation for BMS China employees to visit a BMS facility in the United States.

The idea for the Buddy program was first introduced during the 2017 R&D Symposium, and the first participant, Xiaoqing Zhang, met her global buddies Nivedita Annur, and Yali Fu, Clinical Trial Leads, at the Princeton Pike facility last October.

The program is delivering good results for both BMS and the PAN group, whose membership is increasing as the China buddies become PBRG ambassadors. “Our first China buddy, Xiaoqing Zhang, Medical Director of BMS China, has become a PAN site lead and helped to launch our China chapter in December,” said Jing. “It’s very exciting to see the China buddies helping to drive the growth of BMS and of PAN in China.”

To date, a total of 16 candidates have enrolled in the program, with two sessions completed and three in progress.

“As a relatively new member of the company, as compared to other participants, I think I have benefited the most from the in-person and personal contact with relevant counterparts from HQ and other global function through my trip,” said Lulu Li, associate director, regulatory policy, GRS Mainland China & Hong Kong. As the China regulatory landscape continues to evolve, it is critical for us to establish an effective communication mechanism across the various functions and to engage global subject matter experts for review of the significance and impact of the policy changes in China.”

“The trip has also provided me with a great exposure to the key trade associations that BMS is partnering with and gain first-hand insights of their priorities and the external platforms we could leverage in policy advocacy in China,” Li added.
