Bristol-Myers Squibb and Infinity Pharmaceuticals Announce a New Clinical Collaboration to EvaluateOpdivo (Nivolumab) in Combination withIPI-549 in Urothelial Cancer

– Plans to InitiateMARIO-275, a Randomized, Global Phase 2 Study in 1H’19 –

NEW YORK and Cambridge, MA – November 5, 2018 –Bristol-Myers Squibb Company (NYSE: BMY) and Infinity Pharmaceuticals, Inc. (NASDAQ: INFI) today announced a clinical trial collaboration to evaluate Bristol-Myers Squibb’sOpdivo(nivolumab) in combination with Infinity’sIPI-549 in patients with advanced urothelial cancer.IPI-549 is an oral immuno-oncology development candidate that is designed to selectively inhibitphosphoinositide-3-kinase (PI3K)-gamma and is the only investigational PI3K-gamma inhibitor in clinical development.

Infinity will operationalizeMARIO-275:MAcrophageReprogramming inImmuno-Oncology, a global, randomized Phase 2 study to evaluate the effect of addingIPI-549 to Opdivo incheckpoint-naïve advanced urothelial cancer patients who have progressed or recurred following treatment with platinum-based chemotherapy. Approximately 150 patients will be randomized between combination therapy and Opdivo monotherapy. The primary endpoint of the trial will be overall response rate, which will be assessed in the overall population as well as in subsets of patients with different baseline levels of myeloid derived suppressor cells (MDSCs). Opdivo is approved for use by the FDA as a single agent in patients with locally advanced or metastatic urothelial cancer who have progressed or recurred following treatment with platinum-based chemotherapy or who have disease progression within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy. In exploratory analyses of theCheckMate-275 data, high levels of MDSCs were associated with shorter overall survival in patients treated with Opdivo². In Infinity’sMARIO-1 trial, MDSCs were reduced in the majority of patients treated withIPI-549 monotherapy.³IPI-549 in combination with Opdivo has been administered to over 80 patients and demonstrated early evidence of clinical activity with translational studies demonstrating evidence ofon-mechanismIPI-549-mediated effects.⁴

“The expansion of our relationship with Infinity underscores our efforts to follow the science and support potential novel combination therapies in immuno-oncology for cancer patients with limited treatment options,” said Fouad Namouni, M.D., Head of Oncology Development, Bristol-Myers Squibb. “Our goal is to determine whether targeting the tumor microenvironment withIPI-549 will enhance the activity of Opdivo for people with urothelial cancer and potentially in other tumor types where MDSCs suppress the immune response.”

“We are excited to advance the development ofIPI-549 further into the checkpoint inhibitortreatment-naïve setting with this randomized study in collaboration with the team at Bristol-Myers Squibb.,” said Dr. Sam Agresta, Chief Medical Officer of Infinity. “There continues to be a significant unmet need for additional treatment options for people living with urothelial cancer, and we are excited to evaluate the potential of this combination.”

Infinity is continuing to evaluateIPI-549 in combination with Opdivo inMARIO-1, a Phase 1/1b study in patients with advanced solid tumors.

Opdivo was the firstPD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world in July 2014, and currently has regulatory approval in 54 countries including the United States, Japan, and in the European Union.

AboutOpdivo

Opdivo is a programmeddeath-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 ofPD-L1 expression.

In July 2014, Opdivo was the firstPD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world. Opdivo is currently approved in more than 60 countries,

including the United States, the European Union, and Japan. 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.

Withhold OPDIVO in patients withnew-onset moderate to severe neurologic signs or symptoms and evaluate to rule out other causes. If other etiologies are ruled out, administer corticosteroids and permanently discontinue OPDIVO for immune-mediated encephalitis. In patients receiving OPDIVO monotherapy, encephalitis occurred in 0.2% (3/1994) of patients. Fatal limbic encephalitis occurred in one patient after 7.2 months of exposure despite discontinuation of OPDIVO and administration of corticosteroids.

Other Immune-Mediated Adverse Reactions

Based on the severity of the adverse reaction, permanently discontinue or withhold OPDIVO, administer high-dose corticosteroids, and, if appropriate, initiate hormone-replacement therapy. Across clinical trials of OPDIVO, the following clinically significant immune-mediated adverse reactions, some with fatal outcome, occurred in <1.0% of patients receiving OPDIVO: myocarditis, rhabdomyolysis, myositis, uveitis, iritis, pancreatitis, facial and abducens nerve paresis, demyelination, polymyalgia rheumatica, autoimmune neuropathy, GuillainBarré syndrome, hypopituitarism, systemic inflammatory response syndrome, gastritis, duodenitis, sarcoidosis, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), motor dysfunction, vasculitis, aplastic anemia, pericarditis, and myasthenic syndrome.

If uveitis occurs in combination with other immune-mediated adverse reactions, consider a Vogt-Koyanagi-Harada-like syndrome, which has been observed in patients receiving OPDIVO and may require treatment with systemic steroids to reduce the risk of permanent vision loss.

Infusion Reactions

OPDIVO can cause severe infusion reactions, which have been reported in <1.0% of patients in clinical trials. Discontinue OPDIVO in patients with Grade 3 or 4 infusion reactions. Interrupt or slow the rate of infusion in patients with Grade 1 or 2. In patients receiving OPDIVO monotherapy as a60-minute infusion, infusion-related reactions occurred in 6.4% (127/1994) of patients. In a separate study in which patients received OPDIVO monotherapy as a60-minute infusion or a30-minute infusion, infusion-related reactions occurred in 2.2% (8/368) and 2.7% (10/369) of patients, respectively. Additionally, 0.5% (2/368) and 1.4% (5/369) of patients, respectively, experienced adverse reactions within 48 hours of infusion that led to dose delay, permanent discontinuation or withholding of OPDIVO.

Complications of Allogeneic HSCT after OPDIVO

Complications, including fatal events, occurred in patients who received allogeneic HSCT after OPDIVO. Outcomes were evaluated in 17 patients from Checkmate 205 and 039, who underwent allogeneic HSCT after discontinuing OPDIVO (15 with reduced-intensity conditioning, 2 with myeloablative conditioning). Thirty-five percent (6/17) of patients died from complications of allogeneic HSCT after OPDIVO. Five deaths occurred in the setting of severe or refractory GVHD. Grade 3 or higher acute GVHD was reported in 29% (5/17) of patients. Hyperacute GVHD was reported in 20% (n=2) of patients. A steroid-requiring febrile syndrome, without an identified infectious cause, was reported in 35% (n=6) of patients. Two cases of encephalitis were reported: Grade 3 (n=1) lymphocytic encephalitis without an identified infectious cause, and Grade 3 (n=1) suspected viral encephalitis. Hepatic veno-occlusive disease (VOD) occurred in one patient, who received reduced-intensity conditioned allogeneic HSCT and died of GVHD and multi-organ failure. Other cases of hepatic VOD after reduced-intensity conditioned allogeneic HSCT have also been reported in patients with lymphoma who received aPD-1 receptor blocking antibody before transplantation. Cases of fatal hyperacute GVHD have also been reported. These complications may occur despite intervening therapy betweenPD-1 blockade and allogeneic HSCT.

Follow patients closely for early evidence of transplant-related complications such as hyperacute GVHD, severe (Grade 3 to 4) acute GVHD, steroid-requiring febrile syndrome, hepatic VOD, and other immune-mediated adverse reactions, and intervene promptly.

Embryo-Fetal Toxicity

Based on its mechanism of action, OPDIVO can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with an OPDIVO-containing regimen and for at least 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 an OPDIVO-containing regimen, advise women to discontinue breastfeeding during treatment.

AboutIPI-549 and the Ongoing Phase 1/1b Study

IPI-549 is an investigationalfirst-in-class, oral, immuno-oncology product candidate targeting tumor-associated myeloid cells through selectivephosphoinositide-3-kinase-gamma (PI3K-gamma) inhibition, thereby reducingpro-tumor macrophage function and increasing anti-tumor macrophage function. In preclinical studies,IPI-549 demonstrated the ability to reprogram macrophages from apro-tumor (M2), immune suppressive function, to an anti-tumor (M1) immune activating function and enhance the activity of, and overcome resistance to, checkpoint inhibitors.i ii As such,IPI-549 may have the potential to treat a broad range of solid tumors and represents a potentially additive or synergistic approach to restoring anti-tumor immunity in combination with other immunotherapies such as checkpoint inhibitors.

The ongoing Phase 1/1b study being conducted by Infinity is designed to evaluate the safety, tolerability, activity, pharmacokinetics and pharmacodynamics ofIPI-549 as a monotherapy and in combination with nivolumab (Opdivo^®) in approximately 200 patients with advanced solid tumors.iii The study includes monotherapy and combination dose-escalation components, in addition to monotherapy expansion and combination expansion components. The monotherapy dose-escalation and expansion components are complete. The combination dose-escalation component is also complete, and the combination expansion component is enrolling.

The combination expansion component of the study includes multiple cohorts designed to evaluateIPI-549 in patients with specific types of cancer, including patients withnon-small cell lung cancer (NSCLC), melanoma and head and neck cancer whose tumors show initial resistance

or initially respond to but subsequently develop resistance to immune checkpoint blockade therapy. The combination expansion component also includes a cohort of patients with triple negative breast cancer (TNBC) who have not been previously treated with immune checkpoint blockade therapy, a cohort of patients with mesothelioma, a cohort of patients with adrenocortical carcinoma and a cohort of patients with high baseline blood levels of MDSCs.

IPI-549 is an investigational compound and its safety and efficacy has not been evaluated by the U.S. Food and Drug Administration or any other health authority.
