A total of 35 presentations on the application of Tumor Treating Fields in seven cancer types will be presented. Of the 35 presentations, 18 are externally led research. Highlights include data demonstrating the utility of Tumor Treating Fields in various applications and include the following:

A phase 2 pilot study is assessing the safety of Tumor Treating Fields when administered concomitant to radiation therapy in newly diagnosed glioblastoma patients. The interim results found that newly diagnosed GBM patients who received Tumor Treating Fields at the same time of radiation therapy reported similar proportions of Tumor Treating Fields-related skin toxicity as reported by patients in a phase 3 pivotal study of newly diagnosed GBM patients who received Tumor Treating Fields plus temozolomide four weeks or more after radiation therapy (40 percent versus 52 percent). No other toxicities related to Tumor Treating Fields were reported.

A retrospective safety analysis of Novocure’s EF-14 phase 3 pivotal trial found that the combination of Tumor Treating Fields and the chemotherapy lomustine was a feasible combination in glioblastoma patients who had a recurrence.

Novocure has conducted four phase 2 pilot trials of Tumor Treating Fields in solid tumors located outside of the brain: non small-cell lung cancer, mesothelioma, pancreatic cancer and ovarian cancer. A meta-analysis of 176 patients from these trials found that Tumor Treating Fields applied to the lungs, abdomen and upper pelvis did not result in treatment-related pulmonary, cardiac, hematological or gastrointestinal toxicities. The only common adverse event related to Tumor Treating Fields was skin irritation beneath the device transducer arrays.

"In our preclinical studies to date, Tumor Treating Fields has shown promise in multiple solid tumor types, and we believe it may provide additive or synergistic benefits when combined with certain other anti-cancer agents, which may lead to greater efficacy without significantly increasing the side effects," said Dr. Eilon Kirson, Novocure’s Chief Science Officer and Head of Research and Development. "We must first determine the safety of Tumor Treating Fields in any new application before we can explore potential efficacy. These data support the mild side effect profile of Tumor Treating Fields that we have seen to date."

About NT219

NT219 is a small molecule that presents a new concept in cancer therapy by promoting the degradation and inhibiting the phosphorylation of two oncology-related checkpoints, Insulin Receptor Substrates (IRS) 1 and signal transducer and activator of transcription 3 (STAT3), respectively. While targeted anti-cancer drugs inhibit the "ON" signal, NT219 activates the "OFF" switch, extensively blocking major oncogenic pathways. In pre-clinical trials, NT219, in combination with several approved cancer drugs, displayed potent anti-tumor effects and increased survival in various cancers, including sarcoma, melanoma, pancreatic, lung, ovarian, head & neck, prostate and colon cancers, by preventing the tumors from developing drug resistance and reversing resistance after it had been acquired.

Opdivo (nivolumab), First PD-1 Inhibitor to Demonstrate Superior Survival Benefit Compared with Chemotherapy in a Predominantly Chinese Population with Previously Treated Non-Small Cell Lung Cancer (NSCLC)

On April 13, 2018 Bristol-Myers Squibb Company (NYSE: BMY) reported results from the pivotal, randomized Phase 3 CheckMate -078 trial evaluating Opdivo (nivolumab) versus docetaxel in a predominantly Chinese population with previously treated advanced non-small cell lung cancer (NSCLC) (Press release, Bristol-Myers Squibb, APR 13, 2018, View Source [SID1234525480]). In the study, Opdivo demonstrated a statistically significant benefit versus docetaxel on the primary endpoint of overall survival (OS; HR 0.68; 97.7% CI: 0.52 to 0.90; p=0.0006). An OS benefit was observed regardless of PD-L1 expression or tumor histology. Additionally, the two secondary endpoints of objective response rate (ORR) and median duration of response (mDOR) demonstrated durability with Opdivo compared with docetaxel (ORR: 17% vs. 4%; mDOR: not reached vs. 5.3 months, respectively).

Findings will be presented on Monday, April 16 from 4:05-4:20 PM CDT during the Updates in Immuno-Oncology Trials session at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting 2018 in Chicago (Abstract #CT114).

Prof. Yi-Long Wu, principal investigator of CheckMate -078, commented, "The prevalence of lung cancer in China continues to rise, and the disease remains a leading cause of cancer death. Results from CheckMate -078, in which approximately 90% of the patients are from China, are groundbreaking, as they show for the first time an immunotherapy, Opdivo, can significantly improve outcomes across key endpoints, including overall survival, compared with chemotherapy, representing a potential new approach for these patients."

In November 2017, the Company announced that the China Food and Drug Administration had accepted the Biologics License Application for Opdivo for the proposed indication of previously treated NSCLC.

Sabine Maier, M.D., development lead, thoracic cancers, Bristol-Myers Squibb, said, "Opdivo is the only PD-1 inhibitor to have demonstrated an overall survival benefit versus chemotherapy in three randomized Phase 3 lung cancer studies. The positive findings from CheckMate -078 are consistent with the landmark global studies CheckMate -017 and -057, which led to Opdivo becoming a standard of care in most of the world for previously treated squamous and non-squamous NSCLC, and represent our commitment to bring transformational medicines to patients worldwide."

In CheckMate -078, Grade 3-4 treatment-related adverse events (TRAEs) occurred less frequently with Opdivo versus docetaxel (10% vs 47%). Discontinuation due to Grade 3-4 TRAEs were less frequent with Opdivo (3%) than with docetaxel (5%).

Additional Data from CheckMate -078 at AACR (Free AACR Whitepaper) 2018

Additional data presented at AACR (Free AACR Whitepaper) 2018 include progression-free survival with Opdivo versus docetaxel. In the study, Opdivo decreased risk of disease progression by 23% versus chemotherapy (HR 0.77; 95% CI: 0.62, 0.95; p=0.0147).

In addition, subgroup analyses by tumor histology and PD-L1 expression levels showed Opdivo extended OS versus docetaxel. In patients with squamous NSCLC, the hazard ratio (HR) for OS was 0.61 (95% CI: 0.42 to 0.89), and in patients with non-squamous NSCLC, the HR was 0.76 (95% CI: 0.56 to 1.04). In patients whose tumors expressed PD-L1 <1% and ≥1%, the HRs for OS were 0.75 (95% CI: 0.52 to 1.09) and 0.62 (95% CI: 0.45 to 0.87), respectively.

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 non-small cell lung cancer (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) with both squamous and non-squamous NSCLC and across PD-L1 expression status of <1% and ≥1% to receive either Opdivo 3mg/kg intravenously every two weeks (N=338) or docetaxel 75 mg/m2 every three weeks intravenously (N=166) until documented disease progression or unacceptable toxicity.

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

About CheckMate -057 and -017

CheckMate -057 and CheckMate -017 are two separately conducted global Phase 3 studies that evaluated the survival of patients with non-squamous NSCLC (-057) and squamous NSCLC (-017) who had progressed during or after one prior platinum doublet-based chemotherapy regimen.

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. In China, lung cancer is the most commonly diagnosed cancer, with more than 733,000 cases diagnosed in 2015. In addition, 68% of lung cancer patients in China are already at an advanced stage when diagnosed. NSCLC is one of the most common types of the disease and accounts for approximately 85% of diagnoses. About 25% to 30% of all lung cancers are squamous cell carcinomas, and non-squamous NSCLC accounts for approximately 50% to 65% of all lung cancer diagnoses. Survival rates vary depending on the stage and type of the cancer when diagnosed.

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.

In a separate Phase 3 study of YERVOY 3 mg/kg, 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 (2.5%) patients. 1 (0.2%) patient died as a result of toxic epidermal necrolysis. 1 additional patient required hospitalization for severe dermatitis.

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

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

Infusion Reactions

OPDIVO can cause severe infusion reactions, which have been reported in <1.0% of patients in clinical trials. Discontinue OPDIVO in patients with Grade 3 or 4 infusion reactions. Interrupt or slow the rate of infusion in patients with Grade 1 or 2. In patients receiving OPDIVO monotherapy as 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 as a 60-minute infusion prior to the infusion of 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.

Gritstone Oncology to Present First Data Bridging Tumor Antigen Identification and Potent Immunotherapy Delivery in Primates at 2018 AACR Annual Meeting

On April 12, 2018 Gritstone Oncology, a personalized cancer immunotherapy company, reported that preclinical data highlighting the company’s tumor-specific neoantigen (TSNA) identification platform, EDGE (Epitope Discovery in cancer GEnomes), and a novel, potent TSNA delivery approach will be presented during two poster presentations at the 2018 American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting. The meeting is being held April 14-18, 2018 in Chicago (Press release, Gritstone Oncology, APR 12, 2018, View Source [SID1234525288]).

Gritstone Oncology will present prediction data from EDGE demonstrating its ability to select tumor-specific neoantigens that have generated anti-tumor immune responses in humans. In an analysis of independently validated, tumor-relevant T cell responses against neoantigens (including from the US National Cancer Institute), EDGE identified, with good specificity, the majority of neoantigens eliciting a CD8+ T cell response in patients with cancer.

Further, the company will present the first preclinical data, including in non-human primates (NHP), highlighting a potent immunotherapy approach to deliver selected TSNA to patients. The delivery approach comprises a chimpanzee adenoviral vector (ChAdV) for the prime immunization, and a self-replicating, synthetic viral RNA vector (srRNA) for repeated boost immunizations. In preclinical NHP studies, delivery of selected antigens using this sequential (heterologous) prime/boost immunization approach, showed a quick onset of immune activation with induction of high numbers of antigen-specific T cells. In addition, co-administration of anti-CTLA4 further enhanced both the number and function of the elicited T cells, suggesting the system’s potential in combination with checkpoint inhibitors.

"In patients with solid tumors, the generation of a very large number of tumor neoantigen-specific CD8+ T cells is one of the major challenges associated with today’s immunotherapies," said Andrew Allen, M.D., Ph.D., co-founder, president and chief executive officer of Gritstone Oncology. "To leverage the neoantigens selected by EDGE, we have developed a potent immunotherapy regimen, which has produced high level CD8+ T cell responses in NHP. Historically, such models have been highly predictive of immune responses observed in humans, and these data support our plans to initiate clinical trials in in the second half of 2018. We are excited to be presenting our research at this year’s AACR (Free AACR Whitepaper) meeting, demonstrating the applicability of our integrated platform for the development of personalized immunotherapies for difficult-to-treat-cancers."

Abstract Title: A novel heterologous prime boost vaccine system drives tumor specific and potent CD8 T cell responses for cancer immunotherapy

Date & Time: April 15, 2018 from 1:00 to 5:00 p.m. CT

Abstract Findings: Gritstone Oncology has developed a potent heterologous prime/boost immunization approach to deliver predicted TSNAs to patients, which is comprised of a replication incompetent chimpanzee adenoviral vector (ChAdV) for the prime vaccination and a self-replicating, synthetic viral vector (srRNA) for repeated boost vaccinations. In a preclinical model, immunization with either vector resulted in strong antigen-specific CD8 T-cell responses and provided a statistically significant survival advantage to tumor bearing mice when compared to untreated mice. The potency was also tested in a non-human primate model, demonstrating quick onset of T-cell responses one week post ChAdV prime vaccination, with peak T-cell responses at two to three weeks and effectively boosted by the srRNA vector. In addition, co-administration of anti-CTLA4 with the vaccine demonstrated enhanced vaccine-induced immune response.

Abstract Title: Antigen identification for cancer immunotherapy by deep learning on tumor HLA peptides

Date & Time: April 18, 2018 from 8:00 a.m. to 12 p.m. CT

Abstract Findings: Using a large dataset of tumor transcriptomes and immunopeptidomes, Gritstone Oncology has trained a deep learning model (EDGE) to predict the presentation of HLA peptides on tumor cells. The model was tested on HLA presented peptides from held-out tumor samples and demonstrated an approximately 10-fold improvement in positive predictive value compared to standard tools. The model was also tested for its ability to predict neoantigens recognized by T-cells and included the majority (16/23, 70%) of validated neoantigens from an independent test set in a putative 20-mutation personalized immunization.
