Data were presented on the Company’s lead product candidate, duvelisib, a first-in-class oral dual inhibitor of phosphoinositide 3-kinase (PI3K)-delta and PI3K-gamma. An oral presentation by Dr. Matthew Davids, Dana-Farber Cancer Institute, highlighted the latest data from a Phase Ib/II study evaluating duvelisib in combination with FCR (dFCR) as a frontline treatment in younger patients with chronic lymphocytic leukemia (CLL). Three poster presentations highlighted additional duvelisib data, including crossover extension results from the Phase 3 DUO study in patients with relapsed or refractory CLL/small lymphocytic lymphoma (SLL), and new biomarker analyses on the tumor microenvironment modulation from the DUOTM study and the Phase 2 DYNAMOTM study in patients with refractory indolent non-Hodgkin lymphoma (iNHL), and the dual PI3K-delta and PI3K-gamma activity of duvelisib in the CONTEMPOTM study in patients with untreated follicular lymphoma (FL) who are treated with duvelisib in combination with CD20 antibody immunotherapy.

"Dr. Matthew Davids gave an oral presentation of new clinical data from the ongoing Phase Ib/II study evaluating duvelisib in combination with FCR (chemo-immunotherapy) in younger, fit CLL patients," said Diep Le, MD, PhD, Chief Medical Officer of Verastem Oncology. "The combination regimen achieved an overall response rate (ORR) of 94%, including 26% of patients experiencing a complete response or complete response with incomplete blood count recovery (CR/CRi), and 68% achieving a partial response. In addition, patients also experienced a high rate of bone marrow MRD negativity of 76%, which is significantly higher than historical data with FCR. Importantly, the results from this study demonstrated that duvelisib can be combined with a triple chemo-immunotherapy in the front-line setting with an acceptable safety profile".

Dr. Le added, "In addition, the DUO crossover extension data presented build upon the previously reported positive Phase 3 DUO study results and further support duvelisib’s potential as an oral treatment option for patients with relapsed or refractory CLL/SLL. Post-crossover, oral duvelisib monotherapy demonstrated robust clinical activity with a 73% overall response rate (ORR) and a 15-month median PFS in the 89 patients that had previously received ofatumumab on DUO and subsequently progressed. Duvelisib monotherapy also demonstrated a manageable safety profile, with results from this study consistent with the well-characterized safety profile of duvelisib monotherapy in previous studies. It is encouraging to see such a robust response to duvelisib monotherapy, similar to response observed in the parent DUO study, in patients that had failed an additional line of therapy and needed a new treatment option. Collectively, the data presented at EHA (Free EHA Whitepaper) this year continue to provide important insights to guide the future clinical development of duvelisib across a wide range of hematologic malignancies, both as a monotherapy and in combination with other agents."

Jonathan Pachter, PhD, Chief Scientific Officer of Verastem Oncology, commented, "The results presented by Drs. Casulo and Weaver continue to provide important evidence that the dual inhibition of PI3K-δ and PI3K-γ by duvelisib potentially yields added clinical benefit for CLL/SLL and FL patients by targeting both malignant B cells and the supportive tumor microenvironment. For example, these data indicate that duvelisib significantly inhibits chemokines from both cancer cells and the tumor microenvironment, and specifically, PI3K-γ inhibition impairs function of cancer-supportive macrophages and T cells."

Oral Presentation

Title: A Phase IB/II Study of duvelisib in combination with FCR (dFCR) for Frontline Therapy of Younger CLL Patients
Lead author: Dr. Matthew Davids, Dana-Farber Cancer Institute
Final Abstract Code: S807
Summary: FCR is a common initial therapy for younger CLL patients; however, only about 20% will achieve a CR/CRi with minimum residual disease (MRD) negativity in the bone marrow (BM-MRD-). Oral duvelisib had previously shown promising efficacy in CLL, and therefore, the purpose of this study was to investigate the safety and rate of CR/CRi with BM-MRD- following treatment with dFCR. This Phase Ib/II study utilized a standard 3 + 3 design and included 2 dose levels of oral duvelisib (25mg once daily or 25mg twice daily). Duvelisib was given for 1 week with FCR added on Day 8. Up to 6 cycles of dFCR were administered, followed by up to 2 years of duvelisib maintenance.

Among the 31 patients evaluable for post-dFCR response, the ORR was 94%, with 26% achieving a CR (n=4) or CRi (n=4), and 68% achieving a partial response (PR). The best rate of MRD- in the BM in patients with at least one evaluation was 81% (25 of 31). All patients who achieved CR/CRi at primary endpoint were also BM-MRD- (26%). Among survivors, the median follow-up is 24.5 months (range 6.9-46). Two-year progression-free survival and overall survival are both 97%. Eight patients have now completed two years of duvelisib maintenance therapy. The most common all grade non-hematologic adverse events were nausea (72%, all Grade 1/2), fatigue (69%, 3% Grade 3), fever (53%, all Grade 1/2), diarrhea (47%, 3% Grade 3), transaminitis (34%, 28% Grade 3/4), anorexia (34%, all Grade 1/2), vomiting (28%, all Grade 1/2), pruritus (16%, 3% Grade 3), arthritis (9%, all Grade 2) and CMV reactivation (6%, both Grade 2). The most common all grade hematologic adverse events were thrombocytopenia (65%; 34% Grade 3-4), neutropenia (59%; 50% Grade 3-4), and anemia (38%, 16% Grade 3). Serious AEs included transaminitis (n=9, including 5 Grade 3, 4 Grade 4), febrile neutropenia (n=6, all Grade 3), pneumonia (n=6, including 3 cases of PJP despite planned prophylaxis), and colitis (n=2, including 1 Grade 2 and 1 Grade 3). Based on these results the recommended Phase 2 dose of duvelisib in combination with FCR was 25mg twice daily. These results support the thesis that dFCR is an effective regimen for the initial therapy of younger, fit CLL patients and results in a high 81% rate of BM-MRD negativity, significantly higher than historical data with FCR; however infectious and immune-mediated toxicities were observed.

Title: The Efficacy of Duvelisib Monotherapy Following Disease Progression on Ofatumumab Monotherapy in Patients with Relapsed/Refractory CLL or SLL in a Phase 3 Crossover Extension Study
Lead author: Dr. Peter Hillman, St. James University Hospital, Leeds, UK
Final Abstract Code: PF354
Summary: In the previously reported Phase 3 DUO study oral duvelisib monotherapy achieved a statistically significant improvement in median progression-free survival (mPFS) compared to ofatumumab in patients with relapsed or refractory CLL/ SLL (13.3 months versus 9.9 months, respectively; HR=0.52; p<0.0001), along with a manageable safety profile (Flinn, ASH (Free ASH Whitepaper) 2017). The results reported here are from the open-label, DUO crossover extension study where patients with confirmed progressive disease (PD) following treatment with ofatumumab in DUO were given the option to receive treatment with duvelisib. Duvelisib 25mg BID was administered until PD, intolerance, death, or study withdrawal and responses were determined by investigators using modified IWCLL/IWG criteria.

Among the 89 evaluable patients (median three prior therapies (range 2-8), oral duvelisib monotherapy achieved a 73% overall response rate (ORR; 95% CI: 64, 82; 5% complete response with incomplete marrow recovery (CRis), 68% partial responses [PRs]) in the extension study. While on ofatumumab in the DUO study, these 89 patients had a 28% ORR (95% CI: 19, 37; 1% complete response (CR), 27% PRs). The mPFS for duvelisib in the extension study was 15 months (95% CI: 10, 17). While on ofatumumab in the DUO study, these 89 patients had a mPFS of 9 months (95% CI: 9, 11), per investigator’s assessment. Notably, 83% of patients in the duvelisib arm post-crossover had >50% reductions in the size of their target nodal lesions. These same 89 patients had 27% reductions in the size of their target nodal lesions in the DUO ofatumumab arm. Median exposure to duvelisib in the extension study was 32 weeks. The safety profile of duvelisib monotherapy was manageable and consistent with what was observed in the Phase 3 DUO study. The most common Grade ≥3 treatment-emergent adverse events were neutropenia (22%), diarrhea (17%), colitis (9%), pneumonia (9%), rash (5%) and pyrexia (4%). These data build upon the previously reported positive DUO results and further support oral duvelisib monotherapy as an effective oral treatment option for patients with relapsed or refractory CLL/SLL.

Title: The effect of duvelisib, a dual inhibitor of PI3K-δ,γ, on components of the tumor microenvironment in previously untreated follicular lymphoma
Lead author: Dr. Carla Casulo, University of Rochester, Wilmot Cancer Center
Final Abstract Code: PF646
Summary: In previously reported data from the CONTEMPO trial, treatment-naive FL patients treated with duvelisib in combination with rituxumab had an ORR of 93% (36% CRR), and an ORR of 89% (41% CRR) was observed for patients treated with duvelisib in combination with obinutuzumab. In this study, blood samples from healthy volunteers and FL patients treated in the CONTEMPO study, both pre- and post-duvelisib treatment, were analyzed. Ex vivo and in vitro PI3K-γ assays and PI3K-δ assays, with PI3K-δ-selective (idelalisib, TGR-1202, IPI-3063) and PI3K-γ-selective (IPI-549) inhibitors were compared.

Duvelisib and idelalisib potently inhibited LPS-induced human monocytes via PI3K-δ, compared with the PI3K-γ selective IPI-549. For TGR-1202, the IC50 was below the recommended Phase 2 dose (RP2D) clinical exposure. Duvelisib and IPI-549 potently inhibited PI3K-γ dependent fMLP-stimulated human monocytes compared to idelalisib and TGR-1202. In FL patients treated with duvelisib, these PI3K-γ and PI3K-δ selective assays were inhibited 1-4 hours post treatment. Consistent with a PI3K-γ mechanism, both duvelisib and IPI-549 inhibited macrophage polarization to M2, reduced CXCL12-induced macrophage migration, and blocked CXCL12-induced T cell migration, which was not observed with PI3K-δ inhibitor IPI-3063. Collectively, these results support the thesis that duvelisib disrupts PI3K- δ,γ function in FL patients inhibiting the TME through cancer-supportive macrophages and T cells.

Title: Duvelisib inhibition of chemokines in patients with CLL (DUO study) and iNHL (DYNAMO study).
Lead author: Dr. David Weaver, Verastem Oncology
Final Abstract Code: PF649
Summary: PI3K-δ inhibition directly targets proliferation and survival of malignant leukemia and lymphoma cells, while PI3K-γ inhibition modulates the TME through key support cells, including tumor-associated macrophages, nurse-like stroma and T cells, and via soluble factors stimulating tumor growth, survival and migration. Serum samples from patients in the Phase 3 DUO study in relapsed/refractory CLL/SLL and the Phase 2 DYNAMO study in relapsed/refractory indolent NHL were collected at baseline and at C2D1 and used for correlative studies of 24 chemokines, cytokines and serum factors.

In serum samples from the DUO study, CCL1, CCL17, CXCL9, CXCL10, CXCL11, and IL-10 were reduced in patients treated with duvelisib (median 43.8%) but not in those treated with ofatumumab (p≤0.0009). Eight chemokines were reduced in both treatment arms, but the level of reduction was significantly greater for duvelisib-treated patients (median 64.6% for duvelisib versus 26.8% for ofatumumab [p≤0.001]). Many of the chemokines inhibited following duvelisib treatment are associated with the TME, including TNFα, IL-10, IL2Rα, IL12P40, CCL1, CCL17, CCL19, CXCL9, CXCL10, CXCL11, and CXCL13. In serum samples from the DYNAMO study, 13 corresponding chemokines were also inhibited (p≤0.008), including TME factors. Reductions occurred rapidly (by C2D1) in both studies. In DUO, there was a correlation between duration of response and reduction of the following chemokines: CCL17, CXCL11, IL-6, TRAIL, VEGF-D and TPO. These data support the hypothesis that treatment with duvelisib results in significant reduction of chemokines potentially derived from the tumor cells and TME and that further investigation of the effects of duvelisib on TME pharmacodynamic markers is warranted.

About Duvelisib

Duvelisib is a first-in-class investigational oral, dual inhibitor of phosphoinositide 3-kinase (PI3K)-delta and PI3K-gamma, two enzymes known to help support the growth and survival of malignant B-cells and T-cells. PI3K signaling may lead to the proliferation of malignant B- and T-cells and is thought to play a role in the formation and maintenance of the supportive tumor microenvironment.1,2,3 Duvelisib was evaluated in late- and mid-stage extension trials, including DUO, a randomized, Phase 3 monotherapy study in patients with relapsed or refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL),4 and DYNAMO, a single-arm, Phase 2 monotherapy study in patients with refractory indolent non-Hodgkin lymphoma (iNHL).5 Both DUO and DYNAMO achieved their primary endpoints. Verastem Oncology’s New Drug Application (NDA) requesting the full approval of duvelisib for the treatment of patients with relapsed or refractory CLL/SLL, and accelerated approval for the treatment of patients with relapsed or refractory follicular lymphoma (FL) was accepted for filing by the U.S. Food and Drug Administration (FDA), granted Priority Review and assigned a target action date of October 5, 2018. Duvelisib is also being developed by Verastem Oncology for the treatment of peripheral T-cell lymphoma (PTCL), and is being investigated in combination with other agents through investigator-sponsored studies.6 Information about duvelisib clinical trials can be found on www.clinicaltrials.gov.

Phase 3 QuANTUM-R Study Demonstrates Daiichi Sankyo’s Quizartinib Significantly Prolongs Overall Survival as Single Agent Compared to Chemotherapy in Patients with Relapsed/Refractory AML with FLT3-ITD Mutations

On June 16, 2018 Daiichi Sankyo Company, Limited (hereafter, Daiichi Sankyo) reported that positive results from the pivotal QuANTUM-R phase 3 study of single agent quizartinib were presented today as a late-breaking oral presentation in the plenary program at the 23rd Congress of the European Hematology Association (EHA) (Free EHA Whitepaper) in Stockholm, Sweden (Press release, Daiichi Sankyo, JUN 16, 2018, View Source [SID1234527368]).

QuANTUM-R study results showed that patients with relapsed/refractory acute myeloid leukemia (AML) with FLT3-ITD mutations who received single agent quizartinib had a 24 percent reduction in the risk of death compared to patients who received salvage chemotherapy (hazard ratio [HR] = 0.76, P=0.0177, 95 percent CI 0.58-0.98). The median overall survival was 6.2 months (two-sided 95 percent CI 5.3-7.2) for patients treated with quizartinib and 4.7 months (two-sided 95 percent CI 4.0-5.5) for patients treated with salvage chemotherapy. The estimated survival probability at 1 year was 27 percent for patients who received quizartinib and 20 percent for patients who received salvage chemotherapy.

"FLT3-ITD mutated AML represents a high unmet need entity as patients with this aggressive form of the disease have an overall dismal prognosis as evidenced by low response rates to current available therapies, high risk of relapse and a shorter overall survival than those without this mutation," said Jorge E. Cortes, MD, Deputy Chair of the Department of Leukemia in the Division of Cancer Medicine at The University of Texas MD Anderson Cancer Center. "In relapsed/refractory AML with FLT3-ITD mutations, these findings represent the first reported clinical data demonstrating that a single agent can significantly improve overall survival, suggesting that quizartinib could potentially help these patients live longer. Additionally, in the study, a higher proportion of patients received a stem cell transplant in the quizartinib arm compared to the chemotherapy arm."

Secondary and key exploratory analyses including composite complete remission (CRc) are consistent and supportive of the primary analysis.

"Results of this study are consistent with previous phase 2 studies of quizartinib and demonstrate the value of targeting the FLT3-ITD driver mutation. We are encouraged by these data, which will form the basis of regulatory submissions to health authorities. If approved, quizartinib has the potential to redefine the treatment of patients with relapsed/refractory AML with FLT3-ITD mutations," said Antoine Yver, MD, MSc, Executive Vice President and Global Head, Oncology Research and Development, Daiichi Sankyo. "These results also build on our understanding of this difficult-to-treat type of AML as we continue to explore the potential role of quizartinib in combination with chemotherapy and other novel mechanisms to further advance the treatment of patients with relapsed/refractory and newly-diagnosed AML with FLT3-ITD mutations."

The safety profile observed in QuANTUM-R appears consistent with that observed at similar doses in the quizartinib clinical development program. The median treatment duration with quizartinib was 4 cycles of 28 days (97 days; range: 1-1,182 days) versus 1 cycle (range: 1-2) in the salvage chemotherapy arm. The median relative dose intensity for quizartinib was 89 percent. Incidence of treatment-emergent adverse events were comparable between patients who received single agent quizartinib (n=241) and those who received salvage chemotherapy (n=94). The most common adverse events (>30 percent, any Grade) in patients treated with quizartinib versus chemotherapy, respectively, included nausea (48 vs 42 percent), thrombocytopenia (39 vs 34 percent), fatigue (39 vs 29 percent), musculoskeletal pain (37 vs 28 percent), pyrexia (38 vs 45 percent), anemia (37 vs 32 percent), neutropenia (34 vs 26 percent), febrile neutropenia (34 vs 28 percent), vomiting (33 vs 21 percent) and hypokalemia (32 vs 28 percent). The most common adverse events Grade ≥3 (>10 percent of patients) were thrombocytopenia (35 vs 34 percent), anemia (30 vs 29 percent), neutropenia (32 vs 25 percent), febrile neutropenia (31 vs 21 percent), leukopenia (17 vs 16 percent), sepsis/septic shock (16 vs 18 percent), hypokalemia (12 vs 9 percent) and pneumonia (12 vs 9 percent). QTcF >500 msec occurred in 8 patients (3.3 percent) and 2 out of 241 patients discontinued quizartinib due to QTcF prolongation. There were no reported events of Grade 4 QTcF prolongation (Torsade de Pointe, sudden death or cardiac arrest) in the quizartinib arm.

About the QuANTUM-R Study

QuANTUM-R is a pivotal, global, phase 3, open-label randomized study that enrolled 367 patients with FLT3-ITD-mutated AML who were refractory to or in relapse following (with duration of remission of six months or less) standard first-line AML therapy with or without hematopoietic stem cell transplantation (HSCT). Patients were randomized in a 2:1 ratio to receive either single agent oral quizartinib (60 mg, with 30 mg lead-in) or salvage chemotherapy. The primary objective of the study was to determine whether single agent quizartinib prolonged overall survival compared to salvage chemotherapy.

About Quizartinib

Quizartinib, the lead investigational agent in the AML Franchise of the Daiichi Sankyo Cancer Enterprise, is an oral selective FLT3 inhibitor currently in global phase 3 development for relapsed/refractory (QuANTUM-R) and newly-diagnosed (QuANTUM-First) AML with FLT3-ITD mutations, and phase 2 development for relapsed/refractory AML with FLT3-ITD mutations in Japan.

Quizartinib has been granted Fast Track designation by the U.S. Food and Drug Administration (FDA) for the treatment of relapsed/refractory AML. Quizartinib also has been granted Orphan Drug designation by the FDA and European Medicines Agency (EMA) for the treatment of AML. Quizartinib is an investigational agent that has not been approved for any indication in any country. Safety and efficacy have not been established.

About Acute Myeloid Leukemia with FLT3-ITD Mutations

AML is an aggressive blood and bone marrow cancer that causes uncontrolled growth and accumulation of malignant white blood cells that fail to function normally and interfere with the production of normal blood cells.1 The five-year survival rate of AML reported from 2005 to 2011 was approximately 26 percent, which was the lowest of all leukemias.1

FLT3 gene mutations are one of the most common genetic abnormalities in AML.2 The FLT3-ITD mutation is the most common FLT3 mutation, affecting approximately one in four patients with AML.3,4,5,6 Patients with FLT3-ITD-mutated AML have a worse overall prognosis, including an increased incidence of relapse, an increased risk of death following relapseand a higher likelihood of relapse following HSCT as compared to those without this mutation.7,8

ArQule Presents Results from Ongoing Phase 1 Dose Escalation Study of its Reversible BTK Inhibitor, ARQ 531

On June 15, 2018 ArQule, Inc. (Nasdaq:ARQL) today is presenting preliminary results from the Company’s Phase 1 dose escalation study for ARQ 531, an orally bioavailable, potent and reversible inhibitor of both wild type and C481S-mutant Bruton’s tyrosine kinase (BTK) in patients with relapsed or refractory hematologic malignancies at the 23rd Congress of European Hematological Association (EHA) (Free EHA Whitepaper) in Stockholm, Sweden (Press release, ArQule, JUN 15, 2018, View Source [SID1234527333]).

"Preliminary data from our Phase 1 dose escalation trial highlights the potential of ARQ 531 to become a new therapeutic option for patients with B-cell malignancies," commented ArQule Chief Medical Officer and Head of Research and Development, Brian Schwartz, M.D. "There is a significant unmet need for patients with relapsed or refractory B-cell malignancies, in particular those with C481S-mediated resistance to irreversible BTK inhibitors such as ibrutinib. We are especially encouraged by the early signs of anti-tumor activity observed in the first three cohorts."

The reported data from the ongoing Phase 1, open label, single arm dose escalation 3+3 study are from the first three cohorts at dose levels of 5 (n=3), 10 (n=4) and 15 mg (n=4) in patients with relapsed or refractory chronic lymphocytic leukemia (CLL), small lymphocytic leukemia (SLL), Waldenstrom’s macroglobinemia and B-cell Non-Hodgkin lymphoma.

ARQ 531 demonstrated preliminary anti-tumor activity at all dose levels, resulting in an observed tumor reduction of 35% at 5mg, 33% at 10mg, and 29% at 15mg doses. The 29% tumor reduction in the 15mg cohort was achieved after 8 weeks of treatment in a patient with the BTK C481S-mutation, after 5 prior systemic regimens including ibrutinib and venetoclax, with treatment still ongoing. Overall treatment duration ranged from 1 to 46 weeks with 4 of 11 patients treated still ongoing.

ARQ 531 was well tolerated at all three dose levels, supporting continued dose escalation. No dose limiting toxicities or ARQ 531-related Grade 3 or greater adverse events were observed, and the maximum tolerated dose has not been reached.

The half-life of ARQ 531 was between 22-27 hours suggesting the potential for sustained target inhibition and supporting a once daily dosing regimen with preliminary pharmacokinetics showing increases in exposure that are approximately dose proportional.

About BTK and ARQ 531

Bruton’s tyrosine kinase, BTK, is a therapeutic target that has been clinically proven to inhibit B-cell receptor signaling in blood cancers. ARQ 531 is an orally bioavailable, potent and reversible BTK inhibitor. Biochemical and cellular studies have shown that ARQ 531 inhibits both the wild type and C481S-mutant forms of BTK. The C481S-mutation is a known resistance mechanism for first generation irreversible BTK inhibitors. In preclinical studies, ARQ 531 has demonstrated good oral bioavailability as well as favorable pharmacokinetic, pharmacodynamic and metabolic properties.

China National Drug Administration Approves Country’s First Immuno-Oncology Agent, Opdivo (nivolumab injection), for Previously Treated Non-Small Cell Lung Cancer (NSCLC)

On June 15, 2018 Bristol-Myers Squibb Company (NYSE: BMY) announced today that the China National Drug Administration (CNDA) has approved Opdivo (nivolumab injection) for the treatment of locally advanced or metastatic non-small cell lung cancer (NSCLC) after prior platinum-based chemotherapy in adult patients without EGFR or ALK genomic tumor aberrations (Press release, Bristol-Myers Squibb, JUN 15, 2018, View Source [SID1234527347]). This is China’s first and only PD-1 inhibitor and is the only Immuno-Oncology (I-O) agent to demonstrate a survival benefit compared with chemotherapy, based on data from the pivotal Phase 3 CheckMate -078 trial, in which 90% of the patients enrolled were Chinese.

"Lung cancer is a major public health issue in China, representing the highest incidence and mortality among all cancers in the country," said Professor Yi-Long Wu, a tenured director of Guangdong General Hospital and the chair of the Chinese Thoracic Oncology Group. "With most lung cancer patients already at an advanced stage when diagnosed, prolonging survival is an important goal. The approval of Opdivo as the first I-O agent in China is a significant therapeutic advance and is great news for patients and clinicians alike, offering for the first time an I-O treatment option that is proven to extend survival in predominantly Chinese patients with previously treated NSCLC."

The approval is based on results from the Phase 3 CheckMate -078 trial of Opdivo versus chemotherapy among patients with previously treated NSCLC, findings from which were presented at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting in April 2018. In November 2017, the trial was stopped early because the independent Data Monitoring Committee concluded that Opdivo demonstrated superior overall survival compared with chemotherapy. The application later received priority review by the Center for Drug Evaluation in China.

Murdo Gordon, executive vice president and chief commercial officer, Bristol-Myers Squibb, commented, "With approvals in more than 60 countries, Opdivo is a global standard of care for previously treated NSCLC, and we are proud to bring this foundational I-O treatment option to patients and physicians in China. We look forward to continuing to work together with the CNDA to usher in additional healthcare innovations in China, with our shared commitment to moving quickly to help patients."

In CheckMate -078, Opdivo reduced the risk of death by 32% versus chemotherapy, the primary endpoint (HR 0.68; 97.7% CI: 0.52 to 0.90; p=0.0006), in patients with previously treated NSCLC. Both efficacy and safety of Opdivo in this patient population were consistent with the results of the landmark global CheckMate -017 and -057 studies. In CheckMate -078, Grade 3-4 treatment-related adverse events (TRAEs) occurred less frequently with Opdivo versus docetaxel (10% vs. 48%). Discontinuations due to Grade 3-4 TRAEs were also less frequent with Opdivo (3%) than with docetaxel (5%).

"We are thrilled to be able to bring this proven treatment, Opdivo, which has demonstrated superior overall survival versus chemotherapy in previously treated NSCLC patients in China, and are committed to working with stakeholders to ensure patients can quickly access Opdivo," said Fouad Namouni, M.D., head of development, Oncology, Bristol-Myers Squibb. "With more than 7,500 cancer deaths per day estimated in China, we will continue to work with urgency to integrate the unmet treatment needs of Chinese patients in our ongoing I-O global development program, with the goal of bringing them innovative therapies as quickly as possible."

About CheckMate -078

CheckMate -078 is a Phase 3, multinational, randomized study comparing Opdivo with docetaxel in the treatment of patients with Stage IIIb/IV NSCLC whose disease has progressed after platinum-based doublet chemotherapy. The study was conducted primarily in China, with additional study sites in Hong Kong, Russia and Singapore. The trial randomized 504 patients (451 from China, 45 from Russia, 8 from Singapore) without EGFR mutations and with both squamous and non-squamous NSCLC, across PD-L1 expression status of <1% and ≥1%, to receive either Opdivo 3 mg/kg intravenously every two weeks (N=338) or docetaxel 75 mg/m2 intravenously every three weeks (N=166) until documented disease progression or unacceptable toxicity.

The primary endpoint was overall survival (OS), including OS consistency observed with the global CheckMate -017 and CheckMate -057 studies. Secondary endpoints included objective response rate (ORR), progression-free survival, time to treatment failure, efficacy across subgroups, rates of treatment-related adverse events, and rate of disease-related symptom deterioration, as measured by the Lung Cancer Symptom Scale.

Minimum follow-up was 8.8 months. Median OS was 12.0 months in the Opdivo arm and 9.6 months in the chemotherapy arm (HR 0.68; 95% CI: 0.52 to 0.90; p=0.0006). Improved OS with Opdivo versus docetaxel was observed in patients with squamous (HR 0.61; 95% CI: 0.42 to 0.89) and non-squamous (HR 0.76; 95% CI: 0.56 to 1.04) tumor histology, and across all pre-defined subgroups based on tumor PD-L1 expression level. The hazard ratios in patients with tumor PD-L1 expression ≥1% and <1% were 0.62 (95% CI: 0.45 to 0.87) and 0.75 (95% CI: 0.52 to 1.09), respectively. The ORR was 17% with Opdivo versus 4% with docetaxel. Median duration of response was not reached in the Opdivo arm versus 5.3 months in the docetaxel arm. Opdivo decreased risk of disease progression by 23% versus docetaxel (HR 0.77; 95% CI: 0.62 to 0.95; p=0.0147).

About Lung Cancer

Lung cancer is the leading cause of cancer deaths globally, resulting in nearly 1.7 million deaths each year, according to the World Health Organization. Non-small cell lung cancer (NSCLC) is one of the most common types of the disease and accounts for approximately 85% of diagnoses. There are approximately 781,000 new cases of lung cancer diagnosed in China each year, equaling approximately 15 new cases every 10 minutes. This number continues to rise, with more than 800,000 new cases and 700,000 new deaths projected by 2020. Survival rates vary depending on the stage and type of the cancer when diagnosed, with the five-year survival rate lower than 5%. For patients with advanced squamous cell lung cancer and non-squamous NSCLC without any known driver genetic mutation, treatment measures are quite limited. Therefore, long-term survival is the most urgent need of those patients.

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 through their journey.

We understand making the promise of transformational medicines like I-O therapies 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.

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 a 60-minute infusion, infusion-related reactions occurred in 6.4% (127/1994) of patients. In a separate study in which patients received OPDIVO monotherapy as a 60-minute infusion or a 30-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. In patients receiving OPDIVO 1 mg/kg with ipilimumab 3 mg/kg every 3 weeks, infusion-related reactions occurred in 2.5% (10/407) of patients. In patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg, infusion-related reactions occurred in 5.1% (28/547) 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 breastfeeding during treatment with YERVOY and for 3 months following the final dose.

The preclinical eryaspase data will be presented during Poster Session I by Dr. Karine Aguera, ERYTECH’s R&D Project Leader.

Poster Session: Preclinical Demonstration of Intracellular Activity of Asparaginase Encapsulated in Red Blood Cells Both in the Absence and in the Presence of Neutralizing Anti-Asparaginase Antibodies
Abstract #: PF160
Lead Author: Karine Aguera
Poster Session: Poster Session I
Location: Poster Area
Date: Friday, June 15, 2018
Time: 5:30 p.m. – 7:00 p.m. (CEST)

In these in vivo and in vitro preclinical studies, eryaspase was effective in reducing L-asparagine (ASN) levels, both in the presence and absence of neutralizing anti-asparaginase antibodies (nAbs). The preclinical findings, confirmed in additional in vitro experiments with eryaspase, support the theory that intra-cellular asparaginase activity may be responsible for the sustained effect on ASN reduction and can provide a more effective approach for the delivery of the L-asparaginase enzyme in patients with ALL, particularly in patients who have developed nAbs.

The AML Phase 2b trial data will be presented during Poster Session II by Dr. Mathilde Hunault of Centre Hospitalier Universitaire (CHU) d’Angers, France.

Poster Session: A Phase 2b of Eryaspase in Combination with Low-Dose Cytarabine as First-Line Therapy in Elderly Patients with Acute Myeloid Leukemia (ENFORCE – NCT01810705)
Abstract #: PS984
Lead Author: Xavier Thomas
Poster Session: Poster Session II
Location: Poster Area
Date: Saturday, June 16, 2018
Time: 5:30 p.m. – 7:00 p.m. (CEST)
The Phase 2b trial to evaluate the efficacy of eryaspase in elderly AML patients did not meet its primary endpoint to improve overall survival in this difficult-to-treat patient population. Patient selection is likely the most important factor, with enrolled patients remaining only briefly on treatment and unable to achieve a potential drug effect. Individualized risk stratification based on multi-parameter assessment tools and co-morbidity burden should be considered for older adults with AML participating in clinical trials.

ERYTECH also has an abstract on the incidence of Venous Thromboembolism (VTE) in 125 ALL patients, treated in five studies.

Abstract: Venous Thromboembolism in Patients with Acute Lymphoblastic Leukemia (ALL) Treated with Eryaspase (L-Asparaginase Encapsulated in Red Blood Cells)

Abstract #: PB1627
Lead Author: Yves Bertrand
Location: EHA Website Abstracts
The findings of this study show that the risk of VTE with eryaspase treatment in ALL patients was low and observed primarily in adults. The low incidence of these events may be related to decreased incidence of impaired coagulation parameters.

All of the abstracts are currently available on the EHA (Free EHA Whitepaper) website. The posters will be accessible on ERYTECH’s website at the start of each poster session.
