Bristol-Myers Squibb & Immuno-Oncology: Advancing Oncology Research
At Bristol-Myers Squibb, patients are at the center of everything we do. Our vision for the future of cancer care is focused on researching and developing transformational Immuno-Oncology (I-O) medicines for hard-to-treat cancers that could potentially improve outcomes for these patients.

We are leading the scientific understanding of I-O through our extensive portfolio of investigational compounds and approved agents. Our differentiated clinical development program is studying broad patient populations across more than 50 types of cancers with 14 clinical-stage molecules designed to target different immune system pathways. Our deep expertise and innovative clinical trial designs position us to advance the I-O/I-O, I-O/chemotherapy, I-O/targeted therapies and I-O radiation therapies across multiple tumors and potentially deliver the next wave of therapies with a sense of urgency. We also continue to pioneer research that will help facilitate a deeper understanding of the role of immune biomarkers and how a patient’s tumor biology can be used as a guide for treatment decisions throughout their journey.

We understand making the promise of I-O a reality for the many patients who may benefit from these therapies requires not only innovation on our part but also close collaboration with leading experts in the field. Our partnerships with academia, government, advocacy and biotech companies support our collective goal of providing new treatment options to advance the standards of clinical practice.

About Opdivo
Opdivo 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.

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 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.

IMPORTANT SAFETY INFORMATION
WARNING: IMMUNE-MEDIATED ADVERSE REACTIONS
YERVOY can result in severe and fatal immune-mediated adverse reactions. These immune-mediated reactions may involve any organ system; however, the most common severe immune-mediated adverse reactions are enterocolitis, hepatitis, dermatitis (including toxic epidermal necrolysis), neuropathy, and endocrinopathy. The majority of these immune-mediated reactions initially manifested during treatment; however, a minority occurred weeks to months after discontinuation of YERVOY.

Assess patients for signs and symptoms of enterocolitis, dermatitis, neuropathy, and endocrinopathy and evaluate clinical chemistries including liver function tests (LFTs), adrenocorticotropic hormone (ACTH) level, and thyroid function tests at baseline and before each dose.

Permanently discontinue YERVOY and initiate systemic high-dose corticosteroid therapy for severe immune-mediated reactions.

Immune-Mediated Pneumonitis
OPDIVO can cause immune-mediated pneumonitis. Fatal cases have been reported. Monitor patients for signs with radiographic imaging and for symptoms of pneumonitis. Administer corticosteroids for Grade 2 or more severe pneumonitis. Permanently discontinue for Grade 3 or 4 and withhold until resolution for Grade 2.

Immune-Mediated Encephalitis
OPDIVO can cause immune-mediated encephalitis. Evaluation of patients with neurologic symptoms may include, but not be limited to, consultation with a neurologist, brain MRI, and lumbar puncture. Withhold OPDIVO in patients with new-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. Encephalitis occurred in one patient receiving OPDIVO with YERVOY (0.2%) after 1.7 months of exposure.

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

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, infusion-related reactions occurred in 6.4% (127/1994) of patients. In patients receiving OPDIVO with YERVOY, infusion-related reactions occurred in 2.5% (10/407) of patients.

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 a PD-1 receptor blocking antibody before transplantation. Cases of fatal hyperacute GVHD have also been reported. These complications may occur despite intervening therapy between PD-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 their mechanisms of action, OPDIVO and YERVOY 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- or YERVOY- containing regimen and for at least 5 months after the last dose of OPDIVO.

Lactation
It is not known whether OPDIVO or YERVOY 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. Advise women to discontinue nursing during treatment with YERVOY and for 3 months following the final dose.

On July 24, 2017 Seattle Genetics, Inc. (Nasdaq: SGEN), a global biotechnology company, reported a clinical collaboration agreement with Genentech, a member of the Roche Group, for the evaluation of its investigational antibody-drug conjugate (ADC) SGN-LIV1A in combination with atezolizumab (TECENTRIQ) in patients with metastatic triple-negative breast cancer (TNBC) (Press release, Seattle Genetics, JUL 24, 2017, View Source [SID1234519859]). SGN-LIV1A, one of four clinical-stage treatments under development by Seattle Genetics for solid tumors, consists of a LIV-1 targeted monoclonal antibody linked to the potent cell-killing agent monomethyl auristatin E (MMAE). Breast cancer is the most common cancer among women worldwide, with an estimated 1.7 million new cases per year. About 15 to 20 percent of breast cancers are triple negative, which means they lack expression of three breast cancer-associated proteins that serve as key therapeutic targets.

"A key challenge in triple-negative breast cancer, or TNBC, is the lack of available novel targeted treatments. People with this disease generally have poor prognoses. Moreover, current therapies are not curative and only delay disease progression," said Robert Lechleider, M.D., Senior Vice President, Clinical Development of Seattle Genetics. "We have phase 1 data showing that SGN-LIV1A is active as monotherapy in patients with heavily pretreated, metastatic TNBC. Now, under this new collaboration, we will evaluate the potential to expand therapeutic benefit to these patients through combination therapy with atezolizumab."

SGN-LIV1A administered in combination with atezolizumab will be evaluated in a phase 1b/2 clinical study as second-line therapy in patients with metastatic TNBC who have not been previously treated with immunotherapy. This randomized, controlled study is anticipated to enroll up to 45 patients in the treatment arm. Seattle Genetics and Genentech will test the experimental combination in MORPHEUS, Roche’s Novel Cancer Immunotherapy Development Platform. MORPHEUS is a phase 1b/2 adaptive platform to develop combinations of cancer immunotherapies rapidly and efficiently.

Under the terms of the collaboration agreement, Genentech will manage the study operations for the phase 1b/2 trial. Seattle Genetics will retain global development and commercialization rights to SGN-LIV1A.

About SGN-LIV1A
SGN-LIV1A is a novel investigational ADC targeted to LIV-1 protein utilizing Seattle Genetics’ proprietary ADC technology. LIV-1 is expressed by most metastatic breast cancers. It has also been detected in a number of other cancers, including melanoma, prostate, ovarian, and cervical cancer. SGN-LIV1A consists of a LIV-1-targeted monoclonal antibody linked to a potent microtubule-disrupting agent, monomethyl auristatin E (MMAE) by a protease-cleavable linker, using the same technology as ADCETRIS (brentuximab vedotin). It is designed to bind to LIV-1 on cancer cells and release the cell-killing agent into target cells upon internalization. SGN-LIV1A may also cause antitumor activity through other mechanisms, including activation of an immune response.

TECENTRIQ (atezolizumab) is a registered trademark of Genentech, a member of the Roche Group.

On July 24, 2017 OncoCyte Corporation (NYSE MKT:OCX), a developer of novel, non-invasive blood-based liquid biopsy tests to assist in the early detection of cancer, reported that it has successfully completed the Analytical Validation study of its liquid biopsy lung cancer diagnostic test (Press release, BioTime, JUL 24, 2017, View Source [SID1234519858]). The results are consistent with the data reported in May at the American Thoracic Society 2017 International Conference (ATS), which demonstrated sensitivity of 95%, specificity of 73%, and Area Under the Curve (AUC) of 0.92. (An AUC of .92 means that 92% of samples were correctly identified.) The final development step before the commercial launch of the lung cancer diagnostic test will be Clinical Validation, which has commenced with a planned completion in the fourth quarter of this year. If Clinical Validation is successful and OncoCyte’s clinical laboratory receives CLIA certification, then the lung cancer test will be the only commercially available product in what the Company estimates is an up to $4.7 billion annual market opportunity in the U.S.

Analytical Validation
The studies required for Analytical Validation have been established in the CLSI (Clinical Lab Standards Institute) Guidelines. These guidelines cover the testing for such matters as limits of quantitation, precision, reproducibility, and interfering substances. OncoCyte has completed all of these studies successfully.

The new Analytical Validation data supports expectations that the test’s performance will continue to be robust. The completion of the study establishes the performance characteristics of OncoCyte’s lung cancer diagnostic test and, if the Clinical Validation studies are successful, will allow for industrial scale operations under real world conditions. The Company has submitted an abstract to present the data at a scientific conference this year.

"The data seen in this study ensure reliable and actionable liquid biopsy test results that physicians can use in clinical practice to help patients make more informed treatment decisions," stated Lyndal Hesterberg, Ph.D., Senior Vice President, Research and Development. "The successful completion of the Analytical Validation study is an important milestone as we progress toward commercialization of the test in the second half of 2017 following CLIA certification of the Company’s laboratory and completion of the Clinical Validation stage."

"We estimate that our lung cancer confirmatory diagnostic could result in a substantial reduction in the number of unnecessary, expensive lung biopsies performed annually in the U.S., thereby representing a fundamental advancement in the more accurate diagnosis of suspicious lung nodules by allowing physicians to determine which patients need biopsies versus those who may only need follow-up imaging," said William Annett, President and Chief Executive Officer. "We estimate that approximately 1.4 million patients annually in the U.S. could benefit from the test. Depending on market penetration and reimbursable pricing, we believe this could translate into a market opportunity of up to $4.7 billion annually."

Clinical Validation Stage Underway
The final stage of development following the now completed Analytical Validation Study is Clinical Validation. This stage consists of two distinct sets of studies that will be carried out in OncoCyte’s new clinical laboratory. The first step is CLIA Lab Validation. In this study, OncoCyte will assay approximately 120 samples previously tested in the 299-patient study presented at the ATS meeting, with the goal of demonstrating that OncoCyte’s new clinical laboratory provides the same results on clinical samples as those obtained in OncoCyte’s R&D lab. This study has now begun.
On completion of the CLIA Lab Validation study the second step will be two CLIA Lab Clinical Validation studies. In these studies, OncoCyte will perform assays on blinded prospectively collected samples to assess the performance of the full diagnostic system against clinically confirmed diagnoses. OncoCyte will perform Clinical Validation on two sets of samples. The first study will consist of approximately 300 samples, and if the results of the study are consistent with results to date OncoCyte will launch its liquid biopsy lung cancer diagnostic test. All of the samples required for this first study have now been collected.

The second study will be conducted post-launch and on approximately 200 additional samples to provide additional data to increase the likelihood that physicians will adopt the test and that insurance companies and Medicare will provide reimbursement coverage for the test.

CLIA Certification
OncoCyte’s clinical laboratory must receive Clinical Laboratory Improvement Amendment (CLIA) certification from the state of California. The Company’s complete application for CLIA certification was submitted in March 2017 to the California Department of Public Health and is now under active review. The Company expects to receive CLIA certification during the second half of 2017.

Diagnostic Test Accuracy
Sensitivity and specificity are statistical measures of test performance, with sensitivity measuring the percentage of malignant nodules that are identified correctly by the test and specificity measuring the percentage of benign nodules correctly identified. The AUC of a test is a measure of overall global accuracy that combines sensitivity and specificity, with 1.0 being perfect accuracy and 0.50 being a random result. The score of 0.92 reported at the recent ATS meeting means that 92% of samples were correctly identified.

On July 24, 2017 DelMar Pharmaceuticals (Nasdaq: DMPI) ("DelMar" and "the Company"), a biopharmaceutical company focused on the development of new cancer therapies, reported that the Human Genetic Resources Administration of China (HGRAC), has approved the Company’s application to initiate a Phase 2 safety and efficacy study of its lead product candidate VAL-083 in newly diagnosed MGMT-unmethylated glioblastoma multiforme (GBM) (Press release, DelMar Pharmaceuticals, JUL 24, 2017, View Source [SID1234519857]). DelMar was required to obtain HGRAC approval because the trial involves analysis of patient’s MGMT status as a biomarker for patient selection and enrollment.

"Our clinical trials to date have been focused on recurrent GBM for patients whose tumors have recurred following currently approved therapies. Obtaining HGRAC approval represents a significant step toward maximizing the potential benefit of VAL-083 in newly diagnosed GBM for patients whose tumors exhibit features, such as high expression of MGMT, which render them resistant to the current standard-of-care chemotherapy," said Jeffrey Bacha, Chief Executive Officer of DelMar Pharmaceuticals. "Success of VAL-083 as a front-line treatment would be a major turning point for the brain tumor community and this area of science."

Up to 30 newly diagnosed GBM patients whose tumors exhibit high-expression of the DNA-repair enzyme O6-methylguanine methyltransferase (MGMT) will be treated with VAL-083 in combination with radiotherapy to examine the safety and efficacy of VAL-083 in this population. MGMT methylation status will be used as a biomarker for
patient selection and only patients whose tumors are MGMT-unmethylated will be enrolled.

Results of the trial will be used to guide design of global randomized trials, which if successful, would position VAL-083 as a potential replacement for the current standard-of-care (chemoradiation with temozolomide) for the approximately 2/3 of newly diagnosed GBM patients whose tumors feature MGMT-unmethylated GBM.
GBM patients with MGMT-unmethylated tumors exhibit a high expression of the MGMT enzyme, which is directly correlated to resistance to temozolomide, the current front-line chemotherapy used in the treatment of GBM. MGMT-unmethylated patients have particularly poor patient outcomes and significantly reduced survival compared to MGMT-methylated patients.

DelMar has demonstrated that VAL-083’s anti-cancer activity is independent of MGMT expression against multiple GBM cell lines in vitro. VAL-083’s clinical activity against GBM has been established by DelMar’s recent Phase 2 clinical trials in refractory GBM and historical trials conducted by the US National Cancer Institute (NCI). Results of prior NCI-sponsored trials of VAL-083 combined with radiotherapy in newly diagnosed GBM suggest a potential superior benefit of chemoradiation with VAL-083 versus radiotherapy alone (+8.3 months) in comparison to similar studies involving temozolomide or nitrosoureas (+1.2 – 2.5 months).

Mr. Bacha continued, "GBM has been largely left behind in the recent advancements made in the fight against cancer and new therapies improving median survival have been lacking. We strongly believe that VAL-083 represents a potential paradigm shift in the treatment of GBM, particularly for the 2/3 of newly diagnosed GBM patients whose tumors exhibit high expression of MGMT."

The trial is expected to open for enrollment in the coming weeks at Sun Yat-sen University Cancer Center (SYUCC) in Guangzhou, China under the direction of Professor Zhong-ping Chen, M.D., Ph.D., who serves as chair of the Department of NeuroSurgery/Neuro-Oncology at SYUCC. Prof. Chen has authored dozens of publications and been involved in numerous international brain tumor trials. He also currently serves as president of the Chinese Society for NeuroOncology and as editor-in-chief of the Chinese Journal of NeuroOncology. Kun Tuo, a subsidiary of QuintilesIMS, has been retained to monitor and oversee the conduct of the trial. Funding support for the trial will be provided by Guangxi Wuzhou Pharmaceutical Group Co. Ltd. (Guangxi Wuzhou Pharma), under the terms of DelMar’s collaboration with Guangxi Wuzhou Pharma. Further details of the trial can be found at clinicaltrials.gov (Identifier Number: NCT03050736)

About VAL-083
VAL-083 (dianhydrogalactitol) is a "first-in-class", DNA-targeting agent that introduces interstrand DNA cross-links at the N7-position of guanine leading to DNA double-strand breaks and cancer cell death. VAL-083 has demonstrated clinical activity against a range of cancers including GBM in historical clinical trials sponsored by the U.S. National Cancer Institute.

VAL-083 has been granted an orphan drug designation by the U.S. FDA Office of Orphan Products for the treatment of glioma, medulloblastoma and ovarian cancer, and in Europe for the treatment of malignant gliomas.
DelMar has demonstrated that VAL-083’s anti-tumor activity against GBM is unaffected by the expression of MGMT in vitro. Further details regarding these studies can be found at View Source

The Company’s recent outcomes in Phase 1-2 clinical trials suggest that VAL-083 may offer a clinically meaningful survival benefit for patients with recurrent GBM following treatment with both TMZ and bevacizumab. A well-tolerated dosing regimen of 40mg/m2/day on days 1, 2, and 3 of a 21-day cycle was selected for study in subsequent GBM clinical trials.

Based on these results, DelMar has embarked on human clinical trials for VAL-083 across multiple lines of GBM therapy. These trials include, i) an ongoing single-arm, biomarker driven, Phase 2 study to determine if VAL-083 treatment of MGMT-unmethylated adult GBM patients at first recurrence/progression, prior to bevacizumab, improves overall survival, compared to historical control with lomustine (clinicaltrials.gov identifier: NCT02717962); ii) a pivotal, controlled Phase 3 study in temozolomide-Avastin Recurrent GBM ("STAR-3") to evaluate overall survival versus salvage chemotherapy (clinicaltrials.gov identifier: NCT03149575); and iii) a single arm, biomarker driven, Phase 2 study to confirm the tolerability and efficacy of VAL-083 in combination with radiotherapy in newly diagnosed MGMT-unmethylated GBM patients whose tumors are known to express high MGMT levels (clinicaltrials.gov identifier: NCT03050736). DelMar believes that the results of these studies may support a new treatment paradigm in chemotherapeutic regimens for the treatment of GBM.

About Glioblastoma Multiforme (GBM)
Glioblastoma multiforme (GBM) is the most common and aggressive primary brain cancer. GBM has an incidence of two to three per 100,000 adults per year, and accounts for 52 percent of all primary brain tumors. In the US alone, approximately 18,000 people are diagnosed with GBM every year. GBM accounts for 13,000 cancer deaths in the US annually. Current standard of care includes surgery, radiation and treatment with temozolomide (TMZ), however nearly all tumors recur and the prognosis for recurrent GBM is dismal. Most GBM tumors have unmethylated promoter status for O6-methylguanine-DNA-methyltransferase (MGMT); a validated biomarker for TMZ-resistance. Second-line treatment with anti-angiogenic agent bevacizumab has not improved overall survival (OS) and 5-year survival is less than 3%.

On July 24, 2017 Bristol-Myers Squibb Company (NYSE:BMY) reported that the U.S. Food and Drug Administration (FDA) has expanded the indication for Yervoy (ipilimumab) injection for intravenous use to now include the treatment of unresectable or metastatic melanoma in pediatric patients 12 years of age and older (Press release, Bristol-Myers Squibb, JUL 24, 2017, View Source [SID1234519856]).

Yervoy was evaluated in two trials of pediatric patients: a dose-finding study in 33 patients aged two to 21 years with relapsed or refractory solid tumors and an open-label, single-arm trial in 12 adolescents (ages ranging from 12 to 16 years) with previously treated or untreated, unresectable Stage 3 or 4 malignant melanoma. The overall safety profile of Yervoy in children and adolescents was consistent with the safety profile in adults, and similarities in disease between adult and pediatric patients 12 years and older allow for extrapolation of data. Based on a population pharmacokinetic analysis, exposure in adolescents 12 years and older is comparable to that in adults for the approved dose of 3 mg/kg, administered intravenously over 90 minutes every three weeks for a total of four doses.1

Yervoy is associated with a Boxed Warning and can result in severe to fatal immune-mediated adverse reactions. These immune-mediated reactions may involve any organ system; however, the most common severe immune-mediated adverse reactions are enterocolitis, hepatitis, dermatitis (including toxic epidermal necrolysis), neuropathy, and endocrinopathy. Please see below for additional Important Safety Information, including Boxed Warning regarding immune-mediated adverse reactions.

"When my daughter was diagnosed with melanoma, our entire family was devastated," said Brenda Busby, mother to a 12-year-old patient and pediatric program coordinator, Melanoma Research Foundation. "As someone who has lived with the many challenges of pediatric cancer, I know how important it is for patients and their families who face metastatic melanoma to have access to new therapies."

"Metastatic melanoma is extremely rare in children and adolescents, which makes it particularly difficult to investigate in clinical trials. Though designing clinical trials in small pediatric populations can be challenging, this group of investigators committed to bringing a new therapy to those in need," said Lia Gore, MD, University of Colorado School of Medicine and Children’s Hospital of Colorado. "Ipilimumab’s approval represents the culmination of a long effort and gives physicians the ability to expand immuno-oncology – one of the most exciting areas of medicine2 – for the treatment of young adults with metastatic melanoma."

The U.S. FDA approval for Yervoy in patients 12 years and older with metastatic melanoma marks Bristol-Myers Squibb’s first pediatric indication for an immuno-oncology medicine. The expanded indication builds upon six years of experience with Yervoy, which has been used to treat more than 38,000 adult patients with metastatic melanoma since its first approval.3

"Despite significant advancements in oncology research for adults in recent years, treatment options continue to be limited for pediatric patients with metastatic melanoma," said Chris Boerner, PhD, president and head of U.S. commercial operations, Bristol-Myers Squibb. "At Bristol-Myers Squibb, we are committed to providing meaningful support to the pediatric oncology community. This latest approval of Yervoy exemplifies our ongoing effort to expand the availability of therapies for younger cancer patients."

As part of its commitment to children and adolescents with cancer, Bristol-Myers Squibb continues to explore pediatric applications for investigational oncology agents within its broad development program. In addition, Bristol-Myers Squibb supports organizations and initiatives focused on pediatric patients and their families.

About the Yervoy Studies in Pediatric Patients
Yervoy has been evaluated in a total of 45 pediatric patients across two clinical trials. The safety and effectiveness of Yervoy have been established in pediatric patients 12 years and older. The use of Yervoy in this age group is supported by evidence from adequate and well-controlled studies of Yervoy in adults and population pharmacokinetic data demonstrating that the exposure at a dose of 3 mg/kg in the pediatric and adult populations is comparable. In addition, the tumor biology and the course of advanced melanoma is sufficiently similar in adults and pediatric patients 12 years and older to allow extrapolation of data from adults to pediatric patients.

In a dose-finding trial, Yervoy was evaluated in 33 pediatric patients with relapsed or refractory solid tumors. Patients enrolled in the study ranged from two to 21 years of age, with a median age of 13 years, and 20 of the patients were 12 years of age or older. Yervoy was administered at doses of 1, 3, 5 and 10 mg/kg intravenously over 90 minutes every three weeks for four doses and then every 12 weeks thereafter until progression or treatment discontinuation.1


Yervoy was also evaluated in an open-label, single-arm trial in 12 pediatric patients 12 years and older with previously treated or untreated, unresectable Stage 3 or 4 malignant melanoma. Patients received Yervoy 3 mg/kg (four patients) or 10 mg/kg (eight patients) intravenously over 90 minutes every three weeks for four doses.1

Of the 17 patients 12 years of age and older with melanoma treated with Yervoy across both studies, two patients experienced objective responses, including one partial response that was sustained for 16 months.1

The approved dose for Yervoy in pediatric patients with unresectable or metastatic melanoma is 3 mg/kg, administered intravenously over 90 minutes every three weeks for a total of four doses.
About the Population Pharmacokinetic Analysis
Based on a population pharmacokinetic analysis using available pooled data from 565 patients from four phase 2 adult studies (N=521) and two pediatric studies (N=44), body weight normalized clearance of Yervoy is comparable between adult and pediatric subjects.
Indications and Important Safety Information for YERVOY (ipilimumab)

Indications
YERVOY (ipilimumab) is indicated for the treatment of unresectable or metastatic melanoma in adults and pediatric patients (12 years and older).
YERVOY (ipilimumab) is indicated for the adjuvant treatment of patients with cutaneous melanoma with pathologic involvement of regional lymph nodes of more than 1 mm who have undergone complete resection, including total lymphadenectomy.

Important Safety Information
WARNING: IMMUNE-MEDIATED ADVERSE REACTIONS
YERVOY (ipilimumab) can result in severe and fatal immune-mediated adverse reactions. These immune-mediated reactions may involve any organ system; however, the most common severe immune-mediated adverse reactions are enterocolitis, hepatitis, dermatitis (including toxic epidermal necrolysis), neuropathy, and endocrinopathy. The majority of these immune-mediated reactions initially manifested during treatment; however, a minority occurred weeks to months after discontinuation of YERVOY.

Assess patients for signs and symptoms of enterocolitis, dermatitis, neuropathy, and endocrinopathy and evaluate clinical chemistries including liver function tests (LFTs), adrenocorticotropic hormone (ACTH) level, and thyroid function tests, at baseline and before each dose.
Permanently discontinue YERVOY and initiate systemic high-dose corticosteroid therapy for severe immune-mediated reactions.

Recommended Dose Modifications
Endocrine: Withhold YERVOY for symptomatic endocrinopathy. Resume YERVOY in patients with complete or partial resolution of adverse reactions (Grade 0-1) and who are receiving <7.5 mg prednisone or equivalent per day. Permanently discontinue YERVOY for symptomatic reactions lasting 6 weeks or longer or an inability to reduce corticosteroid dose to 7.5 mg prednisone or equivalent per day.
Ophthalmologic: Permanently discontinue YERVOY for Grade 2-4 reactions not improving to Grade 1 within 2 weeks while receiving topical therapy or requiring systemic treatment.

All Other Organ Systems: Withhold YERVOY for Grade 2 adverse reactions. Resume YERVOY in patients with complete or partial resolution of adverse reactions (Grade 0-1) and who are receiving <7.5 mg prednisone or equivalent per day. Permanently discontinue YERVOY for Grade 2 reactions lasting 6 weeks or longer, an inability to reduce corticosteroid dose to 7.5 mg prednisone or equivalent per day, and Grade 3 or 4 adverse reactions.

Immune-mediated Enterocolitis
Immune-mediated enterocolitis, including fatal cases, can occur with YERVOY. Monitor patients for signs and symptoms of enterocolitis (such as diarrhea, abdominal pain, mucus or blood in stool, with or without fever) and of bowel perforation (such as peritoneal signs and ileus). In symptomatic patients, rule out infectious etiologies and consider endoscopic evaluation for persistent or severe symptoms. Withhold YERVOY for moderate enterocolitis; administer anti-diarrheal treatment and, if persistent for >1 week, initiate systemic corticosteroids (0.5 mg/kg/day prednisone or equivalent). Permanently discontinue YERVOY in patients with severe enterocolitis and initiate systemic corticosteroids (1-2 mg/kg/day of prednisone or equivalent). Upon improvement to ≤Grade 1, initiate corticosteroid taper and continue over at least 1 month. In clinical trials, rapid corticosteroid tapering resulted in recurrence or worsening symptoms of enterocolitis in some patients. Consider adding anti-TNF or other immunosuppressant agents for management of immune-mediated enterocolitis unresponsive to systemic corticosteroids within 3-5 days or recurring after symptom improvement. In patients receiving YERVOY 3 mg/kg in Trial 1, severe, life-threatening, or fatal (diarrhea of ≥7 stools above baseline, fever, ileus, peritoneal signs; Grade 3-5) immune-mediated enterocolitis occurred in 34 YERVOY-treated patients (7%) and moderate (diarrhea with up to 6 stools above baseline, abdominal pain, mucus or blood in stool; Grade 2) enterocolitis occurred in 28 YERVOY-treated patients (5%). Across all YERVOY-treated patients (n=511), 5 (1%) developed intestinal perforation, 4 (0.8%) died as a result of complications, and 26 (5%) were hospitalized for severe enterocolitis. Infliximab was administered to 5 (8%) of the 62 patients with moderate, severe, or life-threatening immune-mediated enterocolitis following inadequate response to corticosteroids. In patients receiving YERVOY 10 mg/kg in Trial 2, Grade 3-5 immune-mediated enterocolitis occurred in 76 patients (16%) and Grade 2 enterocolitis occurred in 68 patients (14%). Seven (1.5%) developed intestinal perforation and 3 patients (0.6%) died as a result of complications.

Immune-mediated Hepatitis
Immune-mediated hepatitis, including fatal cases, can occur with YERVOY. Monitor LFTs (hepatic transaminase and bilirubin levels) and assess patients for signs and symptoms of hepatotoxicity before each dose of YERVOY. In patients with hepatotoxicity, rule out infectious or malignant causes and increase frequency of LFT monitoring until resolution. Withhold YERVOY in patients with Grade 2 hepatotoxicity. Permanently discontinue YERVOY in patients with Grade 3-4 hepatotoxicity and administer systemic corticosteroids (1-2 mg/kg/day of prednisone or equivalent). When LFTs show sustained improvement or return to baseline, initiate corticosteroid tapering and continue over 1 month. Across the clinical development program for YERVOY, mycophenolate treatment has been administered in patients with persistent severe hepatitis despite high-dose corticosteroids. In patients receiving YERVOY 3 mg/kg in Trial 1, severe, life-threatening, or fatal hepatotoxicity (AST or ALT elevations >5× the ULN or total bilirubin elevations >3× the ULN; Grade 3-5) occurred in 8 YERVOY- treated patients (2%), with fatal hepatic failure in 0.2% and hospitalization in 0.4%. An additional 13 patients (2.5%) experienced moderate hepatotoxicity manifested by LFT abnormalities (AST or ALT elevations >2.5× but ≤5× the ULN or total bilirubin elevation >1.5× but ≤3× the ULN; Grade 2). In a dose-finding trial, Grade 3 increases in transaminases with or without concomitant increases in total bilirubin occurred in 6 of 10 patients who received concurrent YERVOY (3 mg/kg) and vemurafenib (960 mg BID or 720 mg BID). In patients receiving YERVOY 10 mg/kg in Trial 2, Grade 3-4 immune- mediated hepatitis occurred in 51 patients (11%) and moderate Grade 2 immune-mediated hepatitis occurred in 22 patients (5%). Liver biopsy performed in 6 patients with Grade 3-4 hepatitis showed evidence of toxic or autoimmune hepatitis.

Immune-mediated Dermatitis
Immune-mediated dermatitis, including fatal cases, can occur with YERVOY. Monitor patients for signs and symptoms of dermatitis such as rash and pruritus. Unless an alternate etiology has been identified, signs or symptoms of dermatitis should be considered immune-mediated. Treat mild to moderate dermatitis (e.g., localized rash and pruritus) symptomatically; administer topical or systemic corticosteroids if there is no improvement within 1 week. Withhold YERVOY in patients with moderate to severe signs and symptoms. Permanently discontinue YERVOY in patients with severe, life- threatening, or fatal immune-mediated dermatitis (Grade 3-5). Administer systemic corticosteroids (1-2 mg/kg/day of prednisone or equivalent). When dermatitis is controlled, corticosteroid tapering should occur over a period of at least 1 month. In patients receiving YERVOY 3 mg/kg in Trial 1, severe, life- threatening, or fatal immune-mediated dermatitis (e.g., Stevens-Johnson syndrome, toxic epidermal necrolysis, or rash complicated by full thickness dermal ulceration, or necrotic, bullous, or hemorrhagic manifestations; Grade 3-5) occurred in 13 YERVOY-treated patients (2.5%); 1 patient (0.2%) died as a result of toxic epidermal necrolysis and 1 additional patient required hospitalization for severe dermatitis. There were 63 patients (12%) with moderate (Grade 2) dermatitis. In patients receiving YERVOY 10 mg/kg in Trial 2, Grade 3-4 immune-mediated dermatitis occurred in 19 patients (4%).
There were 99 patients (21%) with moderate Grade 2 dermatitis.

Immune-mediated Neuropathies
Immune-mediated neuropathies, including fatal cases, can occur with YERVOY. Monitor for symptoms of motor or sensory neuropathy such as unilateral or bilateral weakness, sensory alterations, or paresthesia. Withhold YERVOY in patients with moderate neuropathy (not interfering with daily activities). Permanently discontinue YERVOY in patients with severe neuropathy (interfering with daily activities), such as Guillain-Barre-like syndromes. Institute medical intervention as appropriate for management for severe neuropathy. Consider initiation of systemic corticosteroids (1-2 mg/kg/day of prednisone or equivalent) for severe neuropathies. In patients receiving YERVOY 3 mg/kg in Trial 1, 1 case of fatal Guillain-Barré syndrome and 1 case of severe (Grade 3) peripheral motor neuropathy were reported. Across the clinical development program of YERVOY, myasthenia gravis and additional cases of Guillain-Barré syndrome have been reported. In patients receiving YERVOY 10 mg/kg in Trial 2, Grade 3-5 immune-mediated neuropathy occurred in 8 patients (2%); the sole fatality was due to complications of Guillain-Barré syndrome. Moderate Grade 2 immune-mediated neuropathy occurred in 1 patient (0.2%).

Immune-mediated Endocrinopathies
Immune-mediated endocrinopathies, including life-threatening cases, can occur with YERVOY. Monitor patients for clinical signs and symptoms of hypophysitis, adrenal insufficiency (including adrenal crisis), and hyper- or hypothyroidism. Patients may present with fatigue, headache, mental status changes, abdominal pain, unusual bowel habits, and hypotension, or nonspecific symptoms which may resemble other causes such as brain metastasis or underlying disease. Unless an alternate etiology has been identified, signs or symptoms should be considered immune-mediated. Monitor clinical chemistries, adrenocorticotropic hormone (ACTH) level, and thyroid function tests at the start of treatment, before each dose, and as clinically indicated based on symptoms. In a limited number of patients, hypophysitis was diagnosed by imaging studies through enlargement of the pituitary gland. Withhold YERVOY in symptomatic patients and consider referral to an endocrinologist. Initiate systemic corticosteroids (1-2 mg/kg/day of prednisone or equivalent) and initiate appropriate hormone replacement therapy. In patients receiving YERVOY 3 mg/kg in Trial 1, severe to life-threatening immune-mediated endocrinopathies (requiring hospitalization, urgent medical intervention, or interfering with activities of daily living; Grade 3-4) occurred in 9 YERVOY-treated patients (1.8%). All 9 patients had hypopituitarism, and some had additional concomitant endocrinopathies such as adrenal insufficiency, hypogonadism, and hypothyroidism. Six of the 9 patients were hospitalized for severe endocrinopathies. Moderate endocrinopathy (requiring hormone replacement or medical intervention; Grade 2) occurred in 12 patients (2.3%) and consisted of hypothyroidism, adrenal insufficiency, hypopituitarism, and 1 case each of hyperthyroidism and Cushing’s syndrome. The median time to onset of moderate to severe immune-mediated endocrinopathy was 2.5 months and ranged up to 4.4 months after the initiation of YERVOY. In patients receiving YERVOY 10 mg/kg in Trial 2, Grade 3-4 immune-mediated endocrinopathies occurred in 39 patients (8%) and Grade 2 immune-mediated endocrinopathies occurred in 93 patients (20%). Of the 39 patients with Grade 3-4 immune-mediated endocrinopathies, 35 patients had hypopituitarism (associated with 1 or more secondary endocrinopathies, e.g., adrenal insufficiency, hypogonadism, and hypothyroidism), 3 patients had hyperthyroidism, and 1 had primary hypothyroidism. The median time to onset of Grade 3-4 immune-mediated endocrinopathy was 2.2 months (range: 2 days-8 months). Twenty-seven (69.2%) of the 39 patients were hospitalized for immune-mediated endocrinopathies. Of the 93 patients with Grade 2 immune-mediated endocrinopathy, 74 had primary hypopituitarism (associated with 1 or more secondary endocrinopathy, e.g., adrenal insufficiency, hypogonadism, and hypothyroidism), 9 had primary hypothyroidism, 3 had hyperthyroidism, 3 had thyroiditis with hypo- or hyperthyroidism, 2 had hypogonadism, 1 had both hyperthyroidism and hypopituitarism, and 1 subject developed Graves’ ophthalmopathy. The median time to onset of Grade 2 immune-mediated endocrinopathy was 2.1 months (range: 9 days-19.3 months).

Other Immune-mediated Adverse Reactions, Including Ocular Manifestations
Permanently discontinue YERVOY for clinically significant or severe immune-mediated adverse reactions. Initiate systemic corticosteroids (1-2 mg/kg/day of prednisone or equivalent) for severe immune-mediated adverse reactions. Administer corticosteroid eye drops for uveitis, iritis, or episcleritis. Permanently discontinue YERVOY for immune-mediated ocular disease unresponsive to local immunosuppressive therapy. In Trial 1, the following clinically significant immune-mediated adverse reactions were seen in <1% of YERVOY-treated patients: nephritis, pneumonitis, meningitis, pericarditis, uveitis, iritis, and hemolytic anemia. In Trial 2, the following clinically significant immune- mediated adverse reactions were seen in <1% of YERVOY-treated patients unless specified: eosinophilia (2.1%), pancreatitis (1.3%), meningitis, pneumonitis, sarcoidosis, pericarditis, uveitis and fatal myocarditis. Across 21 dose-ranging trials administering YERVOY at doses of 0.1 to 20 mg/kg (n=2478), the following likely immune-mediated adverse reactions were also reported with <1% incidence: angiopathy, temporal arteritis, vasculitis, polymyalgia rheumatica, conjunctivitis, blepharitis, episcleritis, scleritis, iritis, leukocytoclastic vasculitis, erythema multiforme, psoriasis, arthritis, autoimmune thyroiditis, neurosensory hypoacusis, autoimmune central neuropathy (encephalitis), myositis, polymyositis, ocular myositis, hemolytic anemia, and nephritis.

Embryo-fetal Toxicity
Based on its mechanism of action, YERVOY can cause fetal harm when administered to a pregnant woman. The effects of YERVOY are likely to be greater during the second and third trimesters of pregnancy. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with a YERVOY-containing regimen and for 3 months after the last dose of YERVOY.

Lactation
It is not known whether YERVOY is secreted in human milk. Advise women to discontinue nursing during treatment with YERVOY and for 3 months following the final dose.

Common Adverse Reactions
The most common adverse reactions (≥5%) in patients who received YERVOY at 3 mg/kg were fatigue (41%), diarrhea (32%), pruritus (31%), rash (29%), and colitis (8%). The most common adverse reactions (≥5%) in patients who received YERVOY at 10 mg/kg were rash (50%), diarrhea (49%), fatigue (46%), pruritus (45%), headache (33%), weight loss (32%), nausea (25%), pyrexia (18%), colitis (16%), decreased appetite (14%), vomiting (13%), and insomnia (10%).
