(New York, NY - May 4, 2017) -- Immunotherapy, which has achieved remarkable results in late-stage lung cancer patients, can also hold great hope for newly diagnosed patients, cutting the deadly disease off before it has the chance to take hold and offering a potential cure, according to a new Mount Sinai study published today in Cell. Researchers at The Tisch Cancer Institute at Mount Sinai discovered that some of the same immune cells that allow immunotherapy to turn around some late-stage lung cancers are also present just as the disease takes hold. Before now, little was known about the immune response in early lung cancer, said Miriam Merad, MD, PhD, Professor of Oncological Sciences and of Medicine (Hematology and Medical Oncology) at The Tisch Cancer Institute at Mount Sinai. Dr. Merad and a multidisciplinary team of thoracic surgeons, pathologists, and scientists devised a comprehensive study that began when patients went into surgery to have cancerous lesions removed. The patients' lung tumor samples, samples of surrounding healthy lung tissue, and blood samples were immediately analyzed on a cellular level to map out the immune system components present. The team of researchers crafted a barcoding method that attaches cells in each sample to a different metal isotope, allowing the samples to be pooled for a simultaneous analysis of cells from all three tissue types. The scientists combined this barcoding approach with high-dimensional profiling to map the complete immune landscape to search for tumor-driven changes that would be vulnerable to targeted immunotherapy. The analysis of the samples showed that stage I lung cancer lesions already harbor immune system components that likely compromise anti-tumor T cells' ability to fend off cancer. These single-cell analyses offered unprecedented detail of tumor-driven immune changes, providing a powerful tool for the future design of immunotherapies such as checkpoint inhibitors, particularly those that target the PD-1 and PD-L1 proteins that shield cancer from the immune system; these checkpoint inhibitors have shown great promise in later-stage cancers. "Immunotherapy has mostly been used in advanced or metastatic lung cancer, but its benefit in early-stage tumors remains unknown," Dr. Merad said. "The standard treatment for early lung cancer is normally surgical removal of the lesions--sometimes with chemotherapy and radiation. Our study reveals that early lung lesions are heavily infiltrated with many different immune cells, suggesting that immunotherapy could also work on very early lesions and potentially lead to a cure by heading cancer off at the pass before it really takes root in the lungs." This new research also identified a multitude of additional immunotherapy targets to increase the number of patients that would significantly benefit from immunotherapy, which at the moment remains fairly small. This research is being used to develop immunotherapy trials with early lung cancer patients. "About 50 percent of patients with small lung cancer lesions relapse," Merad said. "And when lung cancer is advanced, chemotherapy does not have a great success rate, so knowing how to attack the cancer at an early stage could have huge impacts on the number of patients relapsing and their overall survival. Our research further corroborates the belief that immunotherapy agents are most efficient at early stages of cancer, particularly in patients who have never been treated with chemotherapy." Raja M. Flores, MD, Chair of the Department of Thoracic Surgery at Mount Sinai Health System, and his team contributed significantly to the study by identifying patients and providing their tissue samples. Mount Sinai's Human Immune Monitoring Center (HIMC) also played an integral role, by providing a platform to analyze patient samples using quality control assays and cutting-edge technology. Through the HIMC, Dr. Merad plans to build a portal to share the results of this study and of other HIMC research to collaborate with colleagues at other cancer centers in the hopes of promoting further cancer and immunology research. This study was funded by Foundation pour la Recherche Medicale DEA20150633125 and NIH grants R01, R01 CA173861, U19AI128949, U24 AI 118644, U19 AI 117873-01.

Type: Journal Article | Journal: Annals of oncology : official journal of the European Society for Medical Oncology | Year: 2016
To examine the relation of carcinoembryonic antigen (CEA) response with tumor response and survival in patients with (K)RAS wild-type metastatic colorectal cancer receiving first-line chemotherapy in the FIRE-3 trial comparing FOLFIRI plus cetuximab versus FOLFIRI plus bevacizumab.CEA response assessed as the percentage of CEA decrease from baseline to nadir was evaluated for its association with tumor response and survival. Receiver operating characteristic analysis revealed an optimal cut-off value of 75% using the maximum of sensitivity and specificity for CEA response to discriminate CEA responders from non-responders. In addition, the time to CEA nadir was calculated.Of 592 patients in the intent-to-treat population, 472 were eligible for analysis of CEA (cetuximab arm: 230 and bevacizumab arm: 242). Maximal relative CEA decrease (%) significantly (P = 0.003) differed between the cetuximab arm (median 83.0%; IQR 40.9%-94.7%) and the bevacizumab arm (median 72.3%; IQR 26.3%-91.0%). In a longitudinal analysis, the CEA decrease occurred faster in the cetuximab arm and was greater than in the bevacizumab arm at all evaluated time points until 56 weeks after treatment start. CEA nadir occurred after 3.3 months (cetuximab arm) and 3.5 months (bevacizumab arm), (P = 0.49). In the cetuximab arm, CEA responders showed a significantly longer progression-free survival [11.8 versus 7.4 months; hazard ratio (HR) 1.53; 95% Cl, 1.15-2.04; P = 0.004] and longer overall survival (36.6 versus 21.3 months; HR 1.73; 95% Cl, 1.24-2.43; P = 0.001) than CEA non-responders. Analysis of extended RAS wild-type patients revealed similar results.In the FIRE-3 trial, CEA decrease was significantly faster and greater in the cetuximab arm than in the bevacizumab arm and correlated with the prolonged survival observed in patients receiving FOLFIRI plus cetuximab.NCT00433927 (ClinicalTrials.gov); AIO KRK0306 FIRE-3.

Selinexor functions by binding with and inhibiting the nuclear export protein XPO1 (also called CRM1), leading to the accumulation of tumor suppressor proteins in the cell nucleus. This reinitiates and amplifies their tumor suppressor function and is believed to lead to the selective induction of apoptosis in cancer cells, while largely sparing normal cells. To date, over 1,900 patients have been treated with selinexor and it is currently being evaluated in several mid- and later-phase clinical trials across multiple cancer indications, including in multiple myeloma in combination with low-dose dexamethasone (STORM) and backbone therapies (STOMP), and in diffuse large B-cell lymphoma (SADAL), and liposarcoma (SEAL), among others. Karyopharm plans to initiate a pivotal randomized Phase 3 study of selinexor in combination with bortezomib (Velcade®) and low-dose dexamethasone (BOSTON) in patients with multiple myeloma in early 2017. Additional Phase 1, Phase 2 and Phase 3 studies are ongoing or currently planned, including multiple studies in combination with one or more approved therapies in a variety of tumor types to further inform the Company's clinical development priorities for selinexor. The latest clinical trial information for selinexor is available at www.clinicaltrials.gov. Karyopharm Therapeutics Inc. (Nasdaq:KPTI) is a clinical-stage pharmaceutical company focused on the discovery and development of novel first-in-class drugs directed against nuclear transport and related targets for the treatment of cancer and other major diseases. Karyopharm's SINE™ compounds function by binding with and inhibiting the nuclear export protein XPO1 (or CRM1). In addition to single-agent and combination activity against a variety of human cancers, SINE™ compounds have also shown biological activity in models of neurodegeneration, inflammation, autoimmune disease, certain viruses and wound-healing.

(New York, NY - December 12, 2016) -- Even before tumors develop, breast cancer cells with a few defined molecular alterations can spread to organs, remain quiet for long periods of time, and then awaken to form aggressive, deadly breast cancer metastasis, says a team of investigators led by researchers at Icahn School of Medicine at Mount Sinai and the University of Regensburg in Germany. They say their finding, published in two papers in the journal Nature, and conducted in animal models and tested in human samples, now solves the mystery of how breast cancer metastasis forms without a primary tumor in this new model of early dissemination and metastasis. Furthermore, a clinical primary tumor may never develop, investigators say. The University of Regensburg team had discovered that cancer cells could spread not only from a highly mutated, overtly evolved and pathologically-defined invasive tumors, but also from early stage cancers commonly considered incapable of spreading cells. However, how these early cancer lesions could spawn cells with traits of malignant tumors was unknown. In two papers published in the journal Nature, and conducted in animal models and tested in human samples, the two teams now have identified the first mechanisms that allow cells to spread early in cancer progression and contribute to metastasis. In the study from Mount Sinai, two changes in mammary cancer cells -- a switched-on oncogene and a turned-off tumor suppressor-- motivated cells to travel from breast tissue to the lungs and other parts of the body. There, the cells stayed quiet until a growth switch was activated and metastases developed in lungs. "This research provides insight into the mechanisms of early cancer spread and may shed light into unexplained phenomena -- among them, why as many as 5 percent of cancer patients worldwide have cancer metastases but no original tumor, and most importantly, why it is so difficult to treat cancer that has spread," says the study's senior investigators, Julio A. Aguirre-Ghiso, PhD, Professor of Medicine, Hematology and Medical Oncology, Maria Soledad Sosa, PhD, Assistant Professor of Pharmacological Sciences, and graduate student Kathryn Harper of The Tisch Cancer Institute at the Icahn School of Medicine at Mount Sinai. "Biologically, this new model of early metastasis challenges everything we thought we knew about how cancer spreads and forms metastasis. It feels like we are going to have to adjust our ideas about the subject of metastasis," he says. "Our hope is that these findings will reshape the way we think about how metastasis should be treated." An important finding from the Mount Sinai team is that most early spread cells remain dormant and most chemotherapy and targeted therapies are aimed at those cells that are proliferative. So early spread cancer cells would escape these conventional therapies even if it kills a primary tumor, Dr. Aguirre-Ghiso says. The work also poses new questions on how early spread cancer cells support metastasis development. Do they do it on their own, do they set the soil for later arriving cells from tumors not caught early, or do they cooperate with later arriving cells? This study reveals a new biological mechanism of early dissemination that must be explored to fully understand how to target the seeds of metastasis. The companion paper headed by Dr. Christoph Klein at the University of Regensburg in Germany, published in the same issue of Nature and co-authored by Dr. Aguirre-Ghiso and members of his team provides additional key mechanistic clues on how early spread is controlled and proof in human cancer cells and tumors of the preclinical findings in this study. Researchers from both teams arrived at their findings independently and then collaborated on the project. Researchers from both teams studied very early stages of breast cancer including DCIS (ductal carcinoma in situ), a noninvasive breast lesion, since 2-3 percent of women who have been treated for DCIS die of metastasis without ever developing a primary tumor. "The best explanation for this phenomenon is that early metastasis occurs before or as DCIS develops. A key finding from this second paper is that in the mouse models, 80% of metastasis originated from the early spread cells and not from the large tumors. In fact, the Klein group identified a mechanism by which spread is more efficient in early lesions than in large tumors. In both studies, investigators found that early cancer cell spread is an extension of the normal process of creating a branching tree of breast milk ducts in females. Two major pathways are activated in this ancient process -- p38, a tumor suppressor, and HER2, an oncogene. Switching off p38 and turning on HER2 activates a module of the EMT (epithelial to mesenchymal transition) signaling pathway. EMT promotes movement of cells during embryogenesis and tissue development. The Klein paper also shows that progesterone receptor signaling, which controls branching of the mammary tree, is important for this early spread by regulating cues involved in EMT and growth programs, a mechanism that was hinted in his earlier studies. As a mammary tree develops, p38, HER2, and EMT are alternatively turned on and off. This, in cooperation with progesterone signaling, allows mammary cells to move through the mammary gland, hollow out a tubular, branching network of milk ducts that flow to the nipple. "Tweaking these pathways are a normal way of forming hollow branching tubes," Dr. Aguirre-Ghiso says. But in their experiments, they found that if HER2 is over-activated (not switched off) or mutated, and p38 is permanently turned off, EMT was continually activated, allowing cells to move out of the mammary gland and into the animal's body through the blood. "We were able to use organoids in three-dimensional cultures, and high resolution imaging directly in the live animal models to actually see these cells enter the blood stream from the mammary tree and travel to the lung, the bone marrow, and other places," he says. "We hadn't thought about oncogenes and tumor suppressors in this way before. This is a new function for these pathways." John S. Condeelis, PhD, co-Director of the Gruss Lipper Biophotonics Center and its Integrated Imaging Program at Einstein, where the high resolution intravital imaging was performed, noted that "We were surprised to learn that cancer cells from DCIS-like lesions could show such robust dissemination using similar machinery found in tumor cells from invasive carcinoma. This is a new insight with implications beyond our expectations." Also David Entenberg MSc, Director of Technological Development and Intravital Imaging who led the imaging efforts within the same Center said, "A few years ago, it would not have been possible to image these disseminating cells inside a living animal with this level of detail. We're pleased that Einstein's imaging technology could, through this collaboration, contribute to the definitive proof of early dissemination." And while both studies focus on the mechanisms of early dissemination in breast cancer, similar processes could control early dissemination and metastasis in other human cancers, including melanoma and pancreatic cancer. In fact, pancreatic cancer early dissemination has also been linked to an EMT process, Dr. Aguirre-Ghiso says. Among the critical avenues they are investigating, Mount Sinai researchers are looking for the growth switch that pushes early spread of dormant cancer cells to form metastases. "While our findings add a whole new level of complexity to the understanding of cancer, they also add energy to our efforts to finally solve the big issue in cancer -- stop the metastasis that kills patients," Dr. Aguirre-Ghiso says.

News Article | December 5, 2016
--Updated Median Duration of Complete Response of 8 Months in All Responding Patients-- NEWTOWN, Pa., Dec. 05, 2016 (GLOBE NEWSWIRE) -- Onconova Therapeutics, Inc. (NASDAQ:ONTX), a clinical-stage biopharmaceutical company focused on discovering and developing novel products to treat cancer, today announced the presentation of data from a Phase 2 clinical trial of oral rigosertib and azacitidine in higher-risk myelodysplastic syndromes (HR-MDS) at the 58th American Society of Hematology (ASH) Annual Meeting in San Diego, California. “The complete remission rate amongst HMA-naïve HR-MDS patients is higher and responses occur more rapidly and durably with the oral rigosertib combination compared to historic single-agent azacitidine,” commented Lewis R. Silverman, M.D., lead investigator in the trial and Associate Professor of Medicine, Hematology and Medical Oncology, at the Icahn School of Medicine at Mount Sinai. “Furthermore, the addition of oral rigosertib to azacitidine does not substantially change the adverse event profile of single-agent azacitidine, and thus may overcome the limitations identified in other HMA-based combinations.” The current standard of care for higher-risk MDS patients is one of two approved hypomethylating agents (azacitidine and decitabine, approved by the FDA in 2004 and 2006). Although these drugs are currently the standard of care in HR-MDS therapy, their overall response rate and duration of benefit is limited to a subset of eligible patients and all responding patients ultimately progress. Thus, there is an urgent need for improving therapeutic options for newly diagnosed HR-MDS patients. The 09-08 trial tested oral rigosertib in combination with injectable azacitidine in a dose ranging study (Phase 1), followed by an expansion cohort (Phase 2) to evaluate the efficacy and safety of the combination. Both 1st-line and 2nd-line HR-MDS patients were included in the study. Summary of Presented Data from the 09-08 Combination Therapy Trial The poster entitled, “Combination of Oral Rigosertib and Injectable Azacitidine in Patients with Myelodysplastic Syndromes (MDS): Results from a Phase II Study,” was presented by Dr. Shyamala Navada of Mount Sinai School of Medicine at the Myelodysplastic Syndromes Session on Sunday, December 4, 2016 at the ASH Annual Meeting in San Diego, California. A copy of the poster is available by visiting the Scientific Presentations section under the Investors & Media tab of Onconova’s website. “We are pleased by the positive efficacy signal observed over extended periods of treatment, and the acceptable tolerability of oral rigosertib and azacitidine in 1st-line HR-MDS,” stated Ramesh Kumar, Ph.D., President and CEO of Onconova. “We presented Phase 2 data to the FDA as part of our End-of-Phase 2 meeting in September 2016, and based on these discussions, we are designing a randomized, placebo controlled Phase 3 clinical trial comparing the combination of oral rigosertib plus azacitidine to azacitidine plus placebo in 1st-line HR-MDS patients with the primary composite endpoint of CR and PR rate per 2006 IWG criteria. Based on our discussions with the FDA the primary efficacy endpoint of this trial will be composite response and not survival, permitting accelerated evaluation of outcomes.” In a second poster at the conference a safety review of 557 MDS/AML patients treated with rigosertib in clinical studies, including the randomized Phase 3 ONTIME trial was presented. The poster entitled, “Comprehensive Analysis of Safety: Rigosertib in 557 Patients with Myelodysplastic Syndromes (MDS) and Acute Myeloid Leukemia (AML),” can be accessed by visiting the Scientific Presentations section under the Investors & Media tab of Onconova’s website. Onconova Therapeutics is a Phase 3 clinical-stage biopharmaceutical company focused on discovering and developing novel products to treat cancer. Onconova's clinical and pre-clinical stage drug development candidates are derived from its extensive chemical library and are designed to work against specific cellular pathways that are important in cancer cells, while causing minimal damage to normal cells. The Company’s most advanced product candidate, rigosertib, is a small molecule inhibitor of cellular signaling and acts as a RAS mimetic. These effects of rigosertib appear to be mediated by direct binding of the compound to the RAS-binding domain (RBD) found in many RAS effector proteins, including the Raf and PI3 kinases. Rigosertib is protected by issued patents (earliest expiry in 2026) and has been awarded Orphan Designation for MDS in the United States, Europe and Japan. In addition to rigosertib, two other candidates are in the clinical stage, and several candidates are in pre-clinical stages. For more information, please visit http://www.onconova.com. The oral form of rigosertib provides a more convenient dosing for use where the duration of treatment may extend to multiple years. To date, more than 350 patients have been treated with the oral formulation of rigosertib, either as a single agent or in combination with other drugs. Phase 1 studies with oral rigosertib were conducted in hematological malignancies, lower-risk MDS and solid tumors. Combination therapy of oral rigosertib with azacitidine and chemoradiotherapy has also been explored. The intravenous form of rigosertib has been employed in Phase 1, 2, and 3 clinical trial involving more than 800 patients, and is currently being evaluated in the randomized Phase 3 global INSPIRE trial as 2nd-line treatment for patients with higher-risk MDS, after failure of hypomethylating agent, or HMA, therapy. This formulation is suited for patients with advanced disease and provides long duration of exposure and ensures adequate dosing under a controlled setting. 1Fenaux et al for the international Vidaza High risk MDS survival study group, Lancet Oncology 2009, 10:223-232.

In these studies, the role of ceramide-1-phosphate (C1P) in the wound-healing process was investigated. Specifi cally, fi broblasts isolated from mice with the known anabolic enzyme for C1P, ceramide kinase (CERK), ablated (CERK mice) and their wild-type littermates (CERK +/+ ) were subjected to in vitro wound-healing assays. Simulation of mechanical trauma of a wound by scratching a monolayer of fi broblasts from CERK +/+ mice demonstrated steadily increasing levels of arachidonic acid in a time-dependent manner in stark contrast to CERK fi broblasts. This observed difference was refl ected in scratch-induced eicosanoid levels. Similar, but somewhat less intense, changes were observed in a more complex system utilizing skin biopsies obtained from CERK-null mice. Importantly, C1P levels increased during the early stages of human wound healing correlating with the transition from the infl ammatory stage to the peak of the fi broplasia stage (e.g., proliferation and migration of fi broblasts). Finally, the loss of proper eicosanoid response translated into an abnormal migration pattern for the fi broblasts isolated from CERK. As the proper migration of fi broblasts is one of the necessary steps of wound healing, these studies demonstrate a novel requirement for the CERK-derived C1P in the proper healing. © 2014 by the American Society for Biochemistry and Molecular Biology, Inc.

In the United States, drugs and medical devices are regulated by the US Food and Drug Administration (FDA). A drug must undergo rigorous testing prior to marketing to and medical use by the general public. The FDA grants marketing approval for drug products based on a comprehensive review of safety and efficacy data. This review article explains the history behind the establishment of the FDA and examines the historical legislation and approval processes for drugs, specifically in the fields of medical oncology and hematology. The agents imatinib (Gleevec, Novartis) and decitabine (Dacogen, Eisai) are used to illustrate both the current FDA regulatory process-specifically the orphan drug designation and accelerated approval process-and why decitabine failed to gain an indication for acute myeloid leukemia. The purpose and construct of the Oncologic Drugs Advisory Committee are also discussed, along with examples of 2 renal cell cancer drugs-axitinib (Inlyta, Pfizer) and tivozanib-that used progression-free survival as an endpoint. Regulatory approval of oncology drugs is the cornerstone of the development of new treatment agents and modalities, which lead to improvements in the standard of cancer care. The future landscape of drug development and regulatory approval will be influenced by the new breakthrough therapy designation, and choice of drug will be guided by genomic insights.
