On June 5, 2017 ImmunoCellular Therapeutics, Ltd. ("ImmunoCellular") (NYSE MKT: IMUC) reported the presentation of data from the phase 1 clinical trial of ICT-121 in patients with recurrent glioblastoma (Press release, ImmunoCellular Therapeutics, JUN 5, 2017, View Source [SID1234519399]). The data from the 20-patient, open-label, multi-center study show that 6 of 20 patients are alive (as of April 2017; survival ranging from 10 to 24 months), and these patients will continue to be followed. As noted in the data presentation, ICT-121 was generally safe and well tolerated. As also noted, although diversity in patient disease severity resulting from a protocol amendment to expand patient eligibility makes interpretation of survival data difficult, the results are encouraging and warrant further investigation. Pending immune response data will provide insight into the potential effectiveness of ICT-121 in inducing the formation of cytotoxic T cells targeting CD133, a cancer stem cell marker. ICT-121 is a dendritic cell-based immunotherapy that specifically targets CD133 which is overexpressed in a wide variety of solid tumors, including glioblastoma as well as non-small cell lung, colon, ovarian, pancreatic and breast cancers. Schedule your 30 min Free 1stOncology Demo! The phase 1 data were presented by Jeremy D. Rudnick, MD, a neurologist in the Johnnie L. Cochran, Jr. Brain Tumor Center in the Department of Neurology at Cedars-Sinai, in a poster titled, "Immunological targeting of CD133 in recurrent glioblastoma: A multi-center Phase I translational and clinical study of autologous CD133 dendritic cell immunotherapy." The data were presented at the 53rd Annual Meeting of the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper), taking place in Chicago.

"The preliminary findings from this phase 1 trial are encouraging, especially in light of the lethality of recurrent glioblastoma and lack of therapeutic options for patients with this disease," said Dr. Rudnick. "We look forward to continuing to follow the patients in this study, and believe that ICT-121 is a potentially promising cancer immunotherapeutic agent."
The phase 1 multi-center trial of ICT-121 targeting CD133 assesses safety and tolerability (primary endpoint) and monitors overall survival and progression-free survival (secondary endpoints). ICT-121 is comprised of autologous dendritic cells that are loaded with two HLA-A2 restricted epitopes of the CD133 antigen. After surgical resection, the HLA-A2-positive patients with recurrent glioblastoma were treated with ICT-121 once a week for 4 weeks during the induction phase and then once every 2 months during the maintenance phase until disease progression, death, ICT-121 depletion or discontinuation. In addition to safety and survival data, the phase 1 trial also assesses immune response by using an ELISpot assay and examining cytokine mRNA expression in response ICT-121 treatment.
"We are encouraged by the preliminary phase 1 results of ICT-121, which we believe underscore the potential of our DC-based approach to cancer immunotherapy," said Anthony J. Gringeri, PhD, ImmunoCellular President and Chief Executive Officer. "We are grateful for the time and effort of the patients, investigators, and staff who supported this clinical study."
About Recurrent Glioblastoma and CD-133
A defining characteristic of glioblastoma is the high incidence of tumor recurrence, which is thought to be triggered by cancer stem cells. These tumorigenic cells tend to be resistant to irradiation and chemotherapeutic agents. The target antigen, CD-133, is overexpressed in glioblastoma tumors and has been identified as a marker for cancer stem cells. Recent clinical trials suggest that the short survival time for these patients emphasizes the important unmet medical need in this disease requiring additional strategic approaches. Dendritic cell immunotherapies, such as ICT-121, could provide benefit to patients by educating their immune systems to induce the formation of cytotoxic T cells that attack tumor cells bearing the target antigen. In addition to immediate attack on tumor cells present at dosing, a long-term memory response effective against tumor recurrence might be induced. Immunotherapy, such as ICT-121, that targets cancer stem cells could be an important treatment for this disease.

Corvus Pharmaceuticals Announces Interim Results Demonstrating Anti-Tumor Activity of CPI-444 in Renal and Lung Cancer Patients Resistant or Refractory to Prior PD-(L)1 Treatment
On June 5, 2017 Corvus Pharmaceuticals, Inc. (NASDAQ:CRVS), a clinical-stage biopharmaceutical company focused on the development and commercialization of novel immuno-oncology therapies, reported interim safety and efficacy results from the renal cell carcinoma (RCC) and non-small cell lung cancer (NSCLC) expansion cohorts in its ongoing Phase 1/1b study (Press release, Corvus Pharmaceuticals, JUN 5, 2017, View Source [SID1234519398]). The data showed that treatment with CPI-444 as a single agent and in combination with atezolizumab (Tecentriq) resulted in anti-tumor activity in patients resistant or refractory to prior treatment with anti-PD-(L)1 antibodies and patients with PD-L1 negative tumors. CPI-444 is a selective and potent inhibitor of the adenosine A2A receptor. Atezolizumab, developed by Genentech, a member of the Roche Group, is a monoclonal antibody designed to target and bind to a protein called PD-L1 (programmed death ligand-1). Schedule your 30 min Free 1stOncology Demo! The interim data were presented today in an oral presentation at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) 2017 Annual Meeting in Chicago by Lawrence Fong, M.D., Professor in Cancer Biology and Leader of the Cancer Immunotherapy Program at the Helen Diller Family Comprehensive Cancer Center at the University of California, San Francisco.

"These preliminary results from the CPI-444 clinical trial show that targeting this novel immunosuppressive pathway can lead to both anti-tumor immune responses and clinical responses in patients who have progressed on anti-PD-(L)1 therapies," said Dr. Fong. "Lung and renal cell cancer patients who do not respond to treatment with PD-(L)1 therapies typically continue to progress rapidly and have very few options to manage their disease, creating a significant unmet need in cancer therapy. These data suggest that CPI-444, both as a single agent and in combination with atezolizumab, may induce tumor regression or disease control in these difficult-to-treat populations."
"The anti-tumor activity and durability of responses and disease control seen to date are encouraging, especially in patients who are resistant/refractory to prior anti-PD-(L)1 therapy and have PD-L1 negative tumors. No therapies are currently approved that can overcome resistance to anti-PD-(L)1 therapies and few, if any, immunotherapies in development have reported benefit in the PD-1 resistant/refractory setting," said Richard A. Miller, an oncologist and co-founder, president and chief executive officer of Corvus. "In addition to our previously announced cohort expansions, based on data reported here, we have met the pre-defined criteria for the second expansion to the maximum number of 48 patients in the RCC cohort receiving combination therapy. We look forward to continuing to evaluate patients with lung and renal cell cancer enrolled in the multiple expansion cohorts, as we believe that targeting the adenosine pathway could lead to new treatment options for patients in this setting."
KEY PATIENT DEMOGRAPHIC DATA
Interim safety and efficacy data on 75 patients with RCC (n=30) or NSCLC (n=45) enrolled in the Phase 1/1b study to date were presented. Of these, 73 percent of RCC patients and 82 percent of NSCLC patients were resistant or refractory to prior therapy with anti-PD-(L)1 antibodies. Of the RCC (n=19) and NSCLC (n=28) patients with archived samples available, 95 percent and 54 percent of patients, respectively, had PD-L1 negative tumors.
KEY STUDY RESULTS IN RCC PATIENTS
An infographic accompanying this announcement is available at View Source
• Best tumor response data for RCC patients are shown in a "waterfall" plot (Figure 1). There were two confirmed partial responses (PR) out of 22 evaluable patients.
One PR was in a patient treated with single agent CPI-444 who was resistant/refractory to prior anti-PD-(L)1 therapy and was PD-L1 negative.
One PR was in an anti-PD-(L)1 treatment-naïve patient treated with combination therapy. The PD-L1 status of this patient treated in combination was not available at the time of the presentation.
The duration of PRs, which are ongoing in these two patients, exceeds eight months and three months.
• 16 patients achieved stable disease, with six of these patients experiencing minor regressions (MR). Four of the patients that achieved an MR were resistant/refractory to prior anti-PD-(L)1 therapy. The remaining patients had progressive disease or progressed before their first CT scan was obtained.
Six patients have had disease control for more than six months (range: 6-12 months), with five of these six patients continuing on therapy (three single agent, two combination).
• For RCC patients with stable disease, an analysis of tumor growth kinetics demonstrated that several patients with documented tumor growth prior to study enrollment, had stabilization or regression of their tumors while receiving treatment with CPI-444, suggesting that treatment altered the behavior of tumor growth.
KEY STUDY RESULTS IN NSCLC PATIENTS
An infographic accompanying this announcement is available at View Source
• Best tumor response data for NSCLC patients are shown in a "waterfall" plot (Figure 2). There were two partial responses (PR) out of 34 evaluable patients.
One confirmed PR was in a patient treated with combination therapy who was resistant/refractory to prior anti-PD-(L)1 therapy and is PD-L1 negative. The PR is ongoing at six months.
One unconfirmed PR is in a patient who received the combination, was resistant/refractory to prior anti-PD-(L)1 therapy, is PD-L1 positive, and is ongoing at two months.
• 22 patients achieved stable disease. Four of the stable disease patients, all of whom were were resistant/refractory to prior anti-PD-(L)1 therapy, had MRs. The remaining patients had progressive disease or progressed before their first CT scan was obtained.
• Four patients with NSCLC, three of whom were resistant/refractory to prior anti-PD-(L)1 therapy, experienced disease control exceeding six months (two single agent, two combination). All of the patients continue on therapy.
SAFETY DATA
CPI-444 continues to be well tolerated to date, with observed adverse events similar to previous reports. For single-agent CPI-444 cohorts, the following Grade 1 and 2 adverse events occurred in 5 percent or more of patients: fatigue, nausea, pruritis, constipation, dizziness, hypertension and fever. For combination therapy cohorts, the following Grade 1 and 2 adverse events occurred in 5 percent or more of patients: fatigue, nausea, pruritis, rash and increase in liver enzymes. In the combination cohort, one patient developed reversible Grade 3 immune-related toxicities.
PHASE 1/1B TRIAL DESIGN
The Phase 1/1b trial is designed to select the dose, assess the safety and examine the activity of CPI-444 as a single agent and in combination with Genentech’s atezolizumab, an anti-PD-L1 antibody, in multiple histologies known to be sensitive to immuno-oncology agents. Patients with non-small cell lung cancer, melanoma, renal cell cancer, triple-negative breast cancer (TNBC), MSI-H colorectal cancer, head and neck cancer, bladder cancer and prostate cancer who have failed standard therapies are eligible. The efficacy endpoints of the study are response rate and disease control rate, which is defined as complete response, partial response (reduction of >30 percent tumor volume) or stable disease (change in tumor volume of between 20 percent growth of tumor and 30 percent reduction of tumor volume). Patients with minor tumor regressions are those with changes in tumor volume of 0 to ≤30 percent reduction in tumor volume. Patients are treated until disease progression or evidence of Grade 3 or 4 toxicity.
The dose-selection part of the study included four cohorts of 12 patients each (N=48) – three cohorts treated with single agent CPI-444 (100 mg twice daily for 14 days; 100 mg twice daily for 28 days; 200 mg once daily for 14 days) and one cohort treated with the combination (CPI-444 50 mg or 100 mg twice daily for 14 days combined with atezolizumab). A treatment cycle is 28 days. Based on biomarker analyses showing sustained, complete blockade of the adenosine A2A receptor in peripheral blood lymphocytes, and evidence of immune activation in circulating lymphocytes, an optimum single agent and combination dose of 100 mg twice a day for 28 days was selected for the second part of the study. As defined in the protocol, patients in the dose-selection stage of the trial receiving the dose and schedule selected for evaluation in the second part of the study are included in the disease-specific cohort efficacy analysis.
The second part of the study is evaluating CPI-444 as a single agent in five disease-specific cohorts (NSCLC, melanoma, RCC, TNBC and a category of "other" that includes MSI-H colorectal cancer, bladder cancer and prostate cancer) and CPI-444 in combination with atezolizumab in five additional matched disease-specific cohorts. Each of the 10 cohorts is initially enrolling 14 patients, but may be expanded based on efficacy. To date, RCC and NSCLC, both single agent and combination cohorts, have met the initial criteria for expansion to 26 patients. Recently, the combination cohort of patients with renal cell cancer met the second criteria for expansion to 48 patients.
Celldex Presents Promising Overall Survival Data from Phase 2 Study of Single-agent Glembatumumab Vedotin in Patients with Checkpoint-Refractory Metastatic Melanoma
On June 5, 2017 Celldex Therapeutics, Inc. (NASDAQ:CLDX) reported positive, mature results from the Company’s Phase 2 study of glembatumumab vedotin in patients with stage III/IV checkpoint inhibitor-refractory, and, if applicable, BRAF/MEK inhibitor-refractory metastatic melanoma (n=62) (Press release, Celldex Therapeutics, JUN 5, 2017, View Source [SID1234519397]). Glembatumumab vedotin is a fully human monoclonal antibody-drug conjugate (ADC) that targets glycoprotein NMB (gpNMB), a protein overexpressed by multiple tumor types, including metastatic melanoma, where more than 80% of patients overexpress the marker. High tumor expression of gpNMB is associated with shorter metastasis-free survival and reduced overall survival.1 Study results were presented today in an oral presentation by Patrick A. Ott, M.D., Ph.D., Clinical Director of Dana-Farber Cancer Institute’s Melanoma Center and its Center for Immuno-Oncology, Assistant Professor of Medicine at Harvard Medical School and an investigator in the study, at the 2017 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting in Chicago.

Median overall survival (OS) for all patients was 9.0 months (95% CI: 6.1, 13.0).
As previously reported in October 2016, 7 of 62 (11%) patients experienced a confirmed response, and an additional three patients also experienced single timepoint partial responses. Since data were reported in October, one patient converted from a confirmed partial response to a confirmed complete response.
Patients who experienced rash in Cycle 1 experienced a more prolonged OS with a median of 15.8 months (p=0.026, HR=0.44) as compared to those who did not experience rash.
"It’s exciting to see clinical activity in this study as very few treatment options exist for melanoma patients who progress after immune checkpoint inhibitors and BRAF targeted therapy," said Dr. Ott. "The single-agent response rate observed in this study, including a complete response, and the duration of the objective responses continue to suggest that glembatumumab vedotin is an active agent in this disease. I am hopeful that leveraging the immune system with checkpoint inhibition in combination with the cytotoxic and immunologic cell death induced by glembatumumab vedotin could bring benefit to an even larger number of patients with melanoma, and I look forward to the outcome of these additional cohorts."
Phase 2 Study Single-agent Cohort Overview and Previously Presented Results
Patients enrolled in this single-agent, open-label cohort of glembatumumab vedotin presented with unresectable stage IV (n=62) melanoma. The median number of prior therapies was three (range of 1 to 8). All patients had been heavily pre-treated and had progressed during or after checkpoint inhibitor therapy, and almost all patients had received both ipilimumab (n=58; 94%) and anti-PD-1/anti-PD-L1 (n=58; 94%) therapy. Twelve patients presented with BRAF mutation, and fifteen had prior treatment with BRAF or BRAF/MEK targeted agents. Patients received glembatumumab vedotin every three weeks until disease progression or intolerance. The safety profile was consistent with prior studies of glembatumumab vedotin with rash, neutropenia and neuropathy experienced as the most significant adverse events.
As previously reported, the primary endpoint of the cohort (6 or more objective responses in the first 52 patients enrolled) was exceeded. Seven of 62 (11%) patients experienced a confirmed response, and an additional three patients also experienced single timepoint responses. The median duration of response was 6.0 months. A 52% disease control rate (patients without progression for greater than three months) was demonstrated, and median PFS for all patients was 4.4 months. Consistent with previous studies in melanoma and breast cancer, rash was associated with greater clinical benefit. Patients who experienced rash in Cycle 1 experienced a 21% confirmed response rate, a more prolonged PFS with a median of 5.5 months (p=0.006; HR=0.39) and a more prolonged OS with a median of 15.8 months (p=0.026, HR=0.44).
Pre-treatment tumor tissue was available for 59 patients. All samples were gpNMB positive, and 78% of patients had tumors with 100% of their epithelial cells expressing gpNMB. Given both the high level of expression and the intensity of expression across this patient population, identifying a potential population for gpNMB enrichment is not feasible; therefore, all patients with metastatic melanoma could be evaluated as potential candidates for treatment with glembatumumab vedotin in future studies.
Ongoing Cohorts Combining Glembatumumab Vedotin with Varlilumab or Checkpoint Inhibitor
In August 2016, the Company announced that the study protocol was amended to add a second cohort of patients to a glembatumumab vedotin and varlilumab combination. Varlilumab is Celldex’s fully human monoclonal agonist antibody that binds and activates CD27, a critical co-stimulatory molecule in the immune activation cascade. This additional cohort has completed enrollment with data presentation expected in the fall of 2017. Celldex is now enrolling patients to a third arm in the study to assess a glembatumumab vedotin and checkpoint combination in patients who have previously progressed on checkpoint inhibitor. This rationale is strongly supported by preclinical data that suggest that the anti-tumor activity may be enhanced with the combination. In addition, due to their direct cytotoxic properties, microtubule-depolymerizing agents like MMAE also appear to convert tumor-resident tolerogenic dendritic cells into active antigen-presenting cells.2
The Company also intends to conduct exploratory analyses of pre-entry skin biopsies in future patients to investigate potential predictors of response to glembatumumab vedotin, given the association of rash and outcome.
About Glembatumumab Vedotin
Glembatumumab vedotin is a fully human monoclonal antibody-drug conjugate (ADC) that targets glycoprotein NMB (gpNMB). gpNMB is a protein overexpressed by multiple tumor types, including breast cancer, melanoma, lung cancer, uveal melanoma and osteosarcoma. gpNMB has been shown to be associated with the ability of the cancer cell to invade and metastasize and to correlate with reduced time to progression and survival in breast cancer. The gpNMB-targeting antibody, CR011, is linked to a potent cytotoxic, monomethyl auristatin E (MMAE), using Seattle Genetics’ proprietary technology. Glembatumumab vedotin is designed to be stable in the bloodstream but to release MMAE upon internalization into gpNMB-expressing tumor cells, resulting in a targeted cell-killing effect. Glembatumumab vedotin is in development for the treatment of locally advanced or metastatic breast cancer with an initial focus in triple negative disease, stage III and IV melanoma, squamous cell lung cancer and uveal melanoma.
Celldex Therapeutics Presents Phase 1 Study of Varlilumab and Opdivo® at 2017 ASCO Annual Meeting
On June 5, 2017 Celldex Therapeutics, Inc. (Nasdaq:CLDX) reported data from the Phase 1 portion of a Phase 1/2 dose escalation and cohort expansion study examining the combination of varlilumab, Celldex’s CD27 targeting investigational immune-activating antibody, and Bristol-Myers Squibb’s anti-PD-1 immunotherapy Opdivo (nivolumab) (Press release, Celldex Therapeutics, JUN 5, 2017, View Source [SID1234519395]). Rachel E. Sanborn, M.D., Co-director of the Providence Thoracic Oncology Program; and Phase I Clinical Trials Program, at the Earle A. Chiles Research Institute, Providence Cancer Center, in Portland, Ore. presented results from the study in an oral presentation entitled, "Clinical Results with Combination of Anti-CD27 Agonist Antibody, Varlilumab, with Anti-PD1 Antibody Nivolumab in Advanced Cancer Patients" at the 2017 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting in Chicago. The primary objective of the Phase 1 portion (n=36) of the study was to evaluate the safety and tolerability of the combination. The Phase 2 portion of the study is expected to complete enrollment in early 2018. Schedule your 30 min Free 1stOncology Demo! "Combining PD-1 inhibition with a potent T cell activating agent provides the opportunity to broaden the number of patients that benefit from checkpoint blockade," said Dr. Sanborn. "While early, we have evidence that this combination does not add toxicity, can turn some ‘immune-cold’ tumors hot, and may have clinical benefit, including in some patients who are not likely to respond to monotherapy. Further elucidating the role of intermittent versus chronic T cell activation through the comparison of alternate varlilumab dosing regimens is an essential component of the ongoing Phase 2 study and could be important in optimizing the potential of this combination."

Key Highlights
• The majority of patients enrolled in the study had PD-L1 negative tumor at baseline and presented with Stage IV, heavily-pretreated disease. 80% of patients enrolled presented with refractory or recurrent colorectal (n=21) or ovarian cancer (n=8), a population expected to have minimal response to checkpoint blockade.
• Combining the potent immune activator, varlilumab, with the PD-1 inhibitor, Opdivo, was well tolerated at all varlilumab dose levels tested without any evidence of increased autoimmunity or inappropriate immune activation.
• Notable disease control observed (stable disease or better for at least 3 months), considering the Stage IV patient population, contained mostly colorectal and ovarian cases (80%).
0.1 mg/kg varlilumab + 240 mg Opdivo: 1/5 (20%)
1 mg/kg varlilumab + 240 mg Opdivo: 5/15 (33%)
10 mg/kg varlilumab + 240 mg Opdivo: 6/15 (40%)
• Three partial responses (PR) observed.
A patient with PD-L1 negative, MMR proficient colorectal cancer, typically unlikely to respond to checkpoint blockade monotherapy, achieved a confirmed PR (presented with metastatic disease to the liver, adrenal gland, abdomen and mesenteric nodule and on study experienced a 95% decrease in target lesions, including resolution of 4/5 target lesions, one 6 mm mesenteric nodule remains). Following completion of combination treatment, the patient continues to receive treatment with Opdivo monotherapy at 22 months. The patients previously received two prior chemotherapy-based regimens, one of which also included EGFR-targeted therapy.
A patient with low PD-L1 (5% expression) squamous cell head and neck cancer achieved a confirmed PR (59% shrinkage) and experienced progression free survival of 6.7 months.
A patient with PD-L1 negative ovarian cancer experienced a single timepoint PR (49% shrinkage) but discontinued treatment to a dose-limiting toxicity (immune hepatitis, an event known to be associated with checkpoint inhibition therapy).
• Migration of immune cells to tumor observed.
Peripheral blood analysis consistent with varlilumab monotherapy, transient increase in inflammatory chemokines (CXCL10, MCP-1, MIP-1β and MIG) and prominent decreases in CD4 and Treg cells without clear association with dose observed.
Tumor biopsy analysis revealed the majority of patients had "cold" tumors at baseline (negative or low PD-L1 and low T cell infiltrate).
A subgroup analysis was conducted in patients with ovarian cancer based on an observed increase of PD-L1 and tumor-infiltrating lymphocytes in this patient population.
• In patients with paired baseline and on-treatment biopsies (n=13), only 15% were PD-L1 positive (≥ 1% tumor cells) at baseline compared to 77% during treatment (p=0.015).
• Patients with increased tumor PD-L1 expression and tumor CD8 T cells correlated with better clinical outcome with treatment (stable disease or better).
• Continuous activation by immune agonists may not be optimal as it could lead to immune exhaustion and dampen the effect of combination therapy. The Phase 2 portion of this study includes alternate varlilumab dosing regimens to evaluate continuous versus intermittent immune activation at higher and lower dose levels and varied frequency.
In April 2016, the trial advanced to the Phase 2 portion of the study and includes cohorts in colorectal cancer, ovarian cancer, head and neck squamous cell carcinoma, renal cell carcinoma and glioblastoma. Varied dosing schedules are being explored in the ovarian and head and neck cohorts. Celldex plans to complete enrollment across all cohorts in the first quarter of 2018 and will work with Bristol-Myers Squibb to present data from the Phase 2 study at a future medical meeting. The primary objective of the Phase 2 study is overall response rate for all cohorts except glioblastoma, where the primary objective is the rate of 12-month overall survival. Secondary objectives include pharmacokinetics assessments, determining the immunogenicity of varlilumab when given in combination with Opdivo and further assessing the antitumor activity of combination treatment, including duration of response, time to response, progression-free survival and overall survival. The study is being conducted by Celldex under a clinical trial collaboration with Bristol-Myers Squibb Company. The companies are sharing development costs.
About Varlilumab
Varlilumab is a fully human monoclonal agonist antibody that binds and activates CD27, a critical co-stimulatory molecule in the immune activation cascade. CD27 can be effectively manipulated with activating antibodies to induce potent anti-tumor responses and may result in fewer toxicities due to its restricted expression and regulation. Varlilumab is a potent anti-CD27 agonist that induces activation and proliferation of human T cells when combined with T cell receptor stimulation. In lymphoid malignancies that express CD27 at high levels, varlilumab may have an additional mechanism of action through a direct anti-tumor effect. Varlilumab has completed a single-agent Phase 1 dose-escalation study, demonstrating potent immunologic activity consistent with its mechanism of action and antitumor activity in patients with advanced, refractory disease. No maximum tolerated dose was reached, and minimal toxicities were observed.

Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world in July 2014, and currently has regulatory approval in more than 60 countries including the United States, Japan, and in the European Union.
About Colorectal Cancer
Worldwide, colorectal cancer is the third most common type of cancer in men and the second most common in women, with approximately 1.4 million new diagnoses in 2012. Of these, nearly 750,000 were diagnosed in men, and 614,000 in women. Globally in 2012, approximately 694,000 deaths were attributed to colorectal cancer. In the U.S. alone, an estimated 135,430 patients will be diagnosed with cancer of the colon or rectum in 2017, and approximately 50,000 are estimated to die of their disease. There is wide variation in 5-year survival rates across the globe, with 5-year survival expected to be around 65% in the developed world and dropping to around 20% in some developing countries. The incidence of microsatellite stability in colorectal tumors varies by stage, with nearly 80% of early stage, resectable tumors and approximately 67% of advanced, metastatic tumors exhibiting MSS.

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.
About Yervoy
Yervoy, which is a recombinant, human monoclonal antibody, blocks the cytotoxic T- lymphocyte-associated antigen-4 (CTLA-4). CTLA-4 is a negative regulator of T-cell activation. Yervoy binds to CTLA-4 and blocks the interaction of CTLA-4 with its ligands, CD80/CD86. Blockade of CTLA-4 has been shown to augment T-cell activation and proliferation. The mechanism of action of Yervoy effect in patients with melanoma is indirect, possibly through T-cell mediated anti-tumor immune responses. On March 25, 2011, the FDA approved Yervoy 3 mg/kg monotherapy for patients with unresectable or metastatic melanoma. Yervoy is now approved in more than 40 countries. There is a broad, ongoing development program in place for Yervoy spanning multiple tumor types. This includes Phase 3 trials in prostate and lung cancers.

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.

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.

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.
