MedicalResearch.com Interview with: Dr. Michael Lotze, MD Chief Scientific Officer, Lion Biotechnologies San Carlos, CA 94070 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Adoptive cell therapy (ACT) with Tumor-infiltrating Lymphocytes (TIL) has shown promise in mediating cancer regression which rely on activation in vivo compared to other immunotherapies that utilize genetically modified T-cells. In TIL therapy, autologous administration of TIL expanded outside the body elicits a highly individualized, specific and potent attack against the tumor. Clinical trials conducted at the National Cancer Institute evaluating TIL therapy for the treatment of metastatic melanoma reported overall response rates of up to 56%. The durable responses observed in these metastatic melanoma patients as well as other patients with cervical cancer, cholangiocarcinoma, and head and neck cancer signal the potential for broader application of TIL therapy to treat patients with other solid tumors, currently an area of substantial unmet clinical need. Lion’s study, recently presented at the Society for Immunotherapy of Cancer, sought to demonstrate the feasibility of culturing and expanding TIL isolated from non-melanoma tumors. We were successful in culturing TIL from tumors obtained from bladder, cervical, head and neck, lung and triple negative breast cancer. (more…)

MedicalResearch.com Interview with: Leslie Chong Imugene Chief Operating Officer Armadale, Australia Leslie Chong Imugene Chief Operating Officer Armadale, Australia   MedicalResearch.com: What is the background for this study? How does HER-Vaxx work? • The technology originates from the Medical University of Vienna, one of Europe’s leading cancer institutes and was identified in 2012 by Dr Axel Hoos (Currently Sr. Vice President of Oncology R&D at GlaxoSmithKline, previous Clinical Lead on Ipilumimab at Bristol-Myers Squibb, a director at Imugene; his only Board seat worldwide) • HER-Vaxx is a peptide vaccine designed to treat tumours that over-express the HER2/neu receptor, such as gastric, breast, ovarian, lung and pancreatic cancers. The vaccine is constructed from various B Cell epitopes of HER2/neu. It has been shown in pre-clinical work and in a Phase 1 study to stimulate a potent polyclonal antibody response to HER2/neu, a commercially and clinically validated cancer target. HER-Vaxx’s successful Phase 1 study was in patients with metastatic breast cancer and the next stage of development will be a Phase 1b/2 study in patients with gastric cancer initiating in 2016.

MedicalResearch.com Interview with: Dr. Luca Richeldi MD PhD Professor of Respiratory Medicine Chair of Interstitial Lung Disease University of Southampton United Kingdom MedicalResearch.com: What is the background for this study? What are the main findings? Response: The data presented at CHEST 2016 were from two post-hoc pooled analyses of the Phase III INPULSIS® trials that evaluated Ofev in idiopathic pulmonary fibrosis, or IPF. Both analyses, using different measures, demonstrate Ofev efficacy in a range of people with IPF, regardless of disease severity at the start of the trials. One analyses investigated the efficacy of Ofev on disease progression in subgroups of patients defined by their GAP (gender, age, physiology) stage. Based on the index, patients were categorized as either GAP stage I or II/III. The analysis showed a similar reduction in disease progression with Ofev versus placebo regardless of GAP stage – meaning no significant difference between GAP stage I versus GAP stage II/III. Disease progression was defined as an absolute decline in forced vital capacity (FVC) ≥5% predicted or death over 52 weeks. (more…)

MedicalResearch.com Interview with: Brett A. King, MD, PhD Assistant Professor Department of Dermatology School of Medicine Yale University New Haven, CT 06520 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Recent advances in the understanding of the pathogenesis of alopecia areata (AA) have yielded Janus kinase (JAK) inhibitors as a promising therapy. Short-term treatment with the JAK inhibitor, tofacitinib, has shown efficacy for severe AA, alopecia totalis (AT), and alopecia universalis (AU), but long-term data are lacking. In this retrospective series of patients aged 18 years or older treated with tofacitinib, of 65 potential responders to therapy, defined as those with AT or AU with duration of current episode of disease of 10 years or less or AA, 77% achieved at least some hair regrowth, with 58% of patients achieving greater than 50% change in SALT score and 20% of patients achieving complete scalp hair regrowth over 4 to 18 months of treatment. Tofacitinib was well tolerated, and there were no serious adverse events. (more…)

MedicalResearch.com Interview with: Jacob Lalezari, MD Quest Clinical Research San Francisco, CA  MedicalResearch.com: What is the background for this study? What are the main findings?
  • Tremendous strides have been made since HIV-1 was first discovered 35 years ago. However, while many HIV patients can control the infection with currently-approved therapies, there is an urgent need for new treatments that can address viruses that are resistant to multiple antiretroviral treatment classes. With people starting treatments earlier and staying on them longer, some patients also face long-term safety and tolerability issues associated with current therapies.
  • Thousands of people are infected with HIV-1 with resistance to three classes of antiretroviral therapy (ART), and are in dire need of treatment. There are limited or no treatment options available for these patients.
  • As multi-drug resistant (MDR) HIV can be transmitted, it is imperative that it be controlled in order to prevent it from becoming a larger problem. It is important to not only focus on the patient being treated but also consider those they could infect.
  • Ibalizumab is the first biologic long-acting investigational ART to show efficacy in patients in just seven days. The Phase III TMB-301 results showed that patients with MDR HIV-1 and with limited treatment options experienced a significant decrease in viral load after receiving a loading dose of ibalizumab (2,000 mg intravenously) in addition to their failing ART therapies.
    •  A total of 40 patients were enrolled in the study.
    • Seven days after the loading dose, 83% of patients achieved a ≥ 0.5 log10 decrease from baseline compared with 3% during the seven-day control period.
    • These results were statistically significant (p<0.0001). Moreover, during that same period, 60% achieved a decrease of ≥1.0 log10.
    • The average viral load decrease for the total population was 1.1 log10
    • There were no treatment-related serious adverse events or discontinuations reported during the initial seven-day treatment period.

MedicalResearch.com Interview with Dr. Ashton A. Connor, MD PanCuRx Translational Research Initiative, Ontario Institute for Cancer Research Dr. Steven Gallinger MD, MSC Division of General Surgery Toronto General Hospital Toronto, ON MedicalResearch.com: What is the background for this study? What are the main findings? Response: The etiology of pancreatic ductal adenocarcinoma (i.e. "pancreatic cancer") and the relationship between the tumour and its characteristic dense, encroaching stroma are still poorly understood. Using whole genome sequencing in two large cohorts, we show that there are four fundamental mutational processes that give rise to pancreatic cancer. With expression data, we also show that the interaction between the tumour and the surrounding stroma varies with the type of mutational process found in the tumour. Specifically, tumours with defective DNA repair, either homologous recombination or mismatch repair deficiency, elicited strong anti-tumour immune responses, likely due to the relatively high numbers of neoantigens in these tumours. Individually, these concepts have been studied in other cancer types, but we are first to apply either of these to pancreatic cancer, and we also the first to integrate these two aspects of cancer biology for any tumour, to our knowledge.

MedicalResearch.com Interview with: Dr. Alan Menter MD Texas Dermatology Associates MedicalResearch.com: What is the background for this study? Response: Psoriasis on the palms and soles of the feet—also known as palmoplantar psoriasis of which there are 2 variants, plaque type or pustular, —can significantly affect a person’s quality of life and is often difficult-to-treat with available treatments. Researchers in this study set out to determine the efficacy and safety of Taltz (ixekizumab) through 60 weeks among patients with moderate-to-severe plaque psoriasis with significant palmoplantar involvement. Plaque psoriasis is the most common form of psoriasis appearing as raised, red patches covered with a silvery white buildup of dead skin cells which are often painful or itchy. This study was an analysis of UNCOVER-3, a Phase 3, multicenter, double-blind, placebo-controlled trial. In the first 12 weeks of this study, patients were randomized to receive placebo, etanercept (50 mg, twice-weekly) or 80 mg of Taltz every two weeks or every four weeks, following an initial starting dose of 160 mg. At 12 weeks, all patients received open-label Taltz every four weeks through 60 weeks. (more…)

MedicalResearch.com Interview with: Melanie Royce, MD, PhD Professor of Medicine University of New Mexico School of Medicine Director of the Breast Multidisciplinary Clinic and Program UNM Cancer Center. Albuquerque, NM MedicalResearch.com: What is the background for this study? What are the main findings? Response: BOLERO-4 is an open label, single-arm, Phase II study that evaluates the combination of everolimus plus letrozole as a first-line treatment for hormone receptor (HR)-positive/HER2-negative advanced breast cancer patients, as well as the use of everolimus plus exemestane beyond initial progression. Results of the Phase II BOLERO-4 clinical trial, presented as an oral presentation at the 2016 European Society for Medical Oncology (ESMO) annual meeting, show preliminary evidence that everolimus in combination with letrozole is effective in treating women with HR-positive/HER2-negative advanced breast cancer in the first-line setting. With follow up of 17.5 months, the median progression-free survival (PFS) is not yet reached. At six months, 83.6% (95% CI: 77.3-88.2%) of women taking everolimus plus letrozole in the first-line setting were without disease progression, and 71.4% (95% CI: 64.0%-77.5%) did not have disease progression at twelve months. Safety findings from BOLERO-4 are consistent with previous studies of everolimus in advanced breast cancer, with the most common adverse events being stomatitis (67.8%), weight loss (42.6%) and diarrhea (36.1%). These adverse events were mostly grade 1 or 2 in severity1. (more…)
Author Interviews, Cancer Research, ESMO, Immunotherapy, NYU / 16.10.2016

MedicalResearch.com Interview with: Arjun Balar, M.D. Assistant Professor of Medicine Director - Genitourinary Medical Oncology Program NYU Perlmutter Cancer Center New York, NY 10016 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Standard treatment for advanced urothelial cancer includes cisplatin-based chemotherapy which has been shown to improve survival. But more than half of patients are not expected tolerate it well and alternative treatment is inferior to cisplatin. The average survival for these patients is in the range of 9-10 months with carboplatin-based treatment, which is the most commonly used alternative to cisplatin. Pembrolizumab is a PD-1 blocking antibody that reactivates the body’s cancer-fighting T-cells (part of the immune system) to fight urothelial cancer. The trial overall enrolled 374 patients who had not yet received any treatment for advanced urothelial cancer, but were considered ineligible for cisplatin chemotherapy. (more…)

MedicalResearch.com Interview with: Dr. Mansoor Raza Mirza, MD Medical Director: Nordic Society of Gynecologic Oncology Board of Directors: Gynecologic Cancer Inter-Group (GCIG) Faculty: European Society of Medical Oncology (ESMO) Faculty: International Gynecologic Cancer Society (IGCS) Chief Oncologist, Rigshospitalet Copenhagen University Hospital Copenhagen, Denmark MedicalResearch.com: What is the background for this study? Response: Recurrent ovarian cancer is an area of significant unmet medical need, and there have been few therapeutic advances for these patients in the past few decades. Niraparib was studied to provide patients with recurrent ovarian cancer an option other than “watchful waiting,” potentially redefining the standard of care for the disease. The ENGOT-OV16/NOVA trial was a Phase 3 double-blind, randomized, placebo-controlled international study of maintenance treatment with niraparib compared with placebo. Niraparib successfully achieved the primary endpoint of prolonging progression-free survival versus placebo in all three prospectively defined primary efficacy populations: (more…)

MedicalResearch.com Interview with: Dr. Mathew Galsky MD Associate Professor, Medicine, Hematology and Medical Oncology Assistant Professor, Urology Director, Genitourinary Medical Oncology The Tisch Cancer Institute Icahn School of Medicine at Mount Sinai MedicalResearch.com: What is the background for this study? What are the main findings? Response: Since the development of combination cisplatin-based chemotherapy for the treatment of metastatic bladder (urothelial) cancer several decades ago, there have been few advances in the treatment of this disease. Further, until recently, there had been no global standard treatment options for patients with metastatic urothelial cancer progressing despite platinum-based chemotherapy. Several lines of evidence suggest that urothelial cancer may be sensitive to immunotherapeutic treatment strategies. Recently, in a phase I/II study published by Sharma and colleagues in Lancet Oncology, the anti-PD-1 antibody Nivolumab demonstrated a durable objective response rate of 24% in patients with metastatic urothelial cancer progressing despite platinum-based chemotherapy. To confirm to antitumor effects of Nivolumab in this patient population, we conducted a large global multicenter single-arm phase II study (more…)

MedicalResearch.com Interview with: Bernard Vanhove, Chief Operating Officer Director of R&D and International Scientific Collaborations Ose Immunotherapeutics MedicalResearch.com: What is the background for this study? What are the main findings? Response: Myeloid suppressive cells, including tumor associated macrophages (TAM) and myeloid-derived suppressor cells (MDSC), represent an abundant immune cell type in the microenvironment of solid tumors where they promote tumor growth, metastases, angiogenesis, inhibiting anti-tumor immune responses. Myeloid cells selectively express SIRPα, an immune tyrosine associated inhibitory receptor (also named CD172a), which controls myeloid functions. We investigated the role of Effi-DEM, new generation checkpoint inhibitor specifically targeting the SIRP- α receptor on the strategic SIRP-α/CD47 pathway in human macrophages polarization and MDSC differentiation. CD47 the ligand of SIRP alpha is ubiquitously expressed in human cells and has been found to be overexpressed in many different tumor cells with a poor prognosis established. Effi-DEM is a selective antagonist of these myeloid suppressive cells as its target SIRP-α is expressed on these cells. Based on this rationale, the preclinical studies conducted with Effi-DEM have demonstrated its potential to transform suppressor myeloid and tumor associated macrophage cells in non-suppressive cells, thereby inducing a reactivation of the immune response. Effi-DEM has also shown to be effective in various aggressive cancer models with encouraging preclinical results, both in monotherapy and in therapeutic combinations with anti-PD-L1 (checkpoint inhibitors) and anti-CD137 (4-1BB) mAbs, activators of the T-cell response. Significant efficacy and survival increase data were demonstrated in models of hepatocarcinoma, melanoma and triple negative breast cancer. (more…)

MedicalResearch.com Interview with: Gabriel N. Hortobagyi, MD, FACP, F.A.S.C.O. Professor of Medicine Nellie B. Connally Chair in Breast Cancer Department of Breast Oncology Co-Director, Multidisciplinary Breast Cancer Research Program University of Texas MD Anderson Cancer Center Houston, Texas MedicalResearch.com: What is the background for this study? What are the main findings? Response: MONALEESA-2 is a Phase III randomized, double blind, placebo controlled, multicenter global registration trial to evaluate the safety and efficacy of LEE011 in combination with letrozole compared to letrozole alone in postmenopausal women with HR+/HER2- advanced breast cancer who received no prior therapy for their advanced breast cancer. The primary efficacy results from the pivotal MONALEESA-2 study show LEE011 (ribociclib) plus letrozole significantly extended progression-free survival (PFS) compared to a standard of care, letrozole, as a first-line treatment in postmenopausal women with hormone receptor positive, human epidermal growth factor receptor-2 negative (HR+/HER2-) advanced or metastatic breast cancer (HR= 0.556; 95% CI: 0.429-0.720; p=0.00000329)1. The results demonstrate that LEE011 plus letrozole reduced the risk of death or progression by 44% over letrozole alone, significantly extending PFS across all patient subgroups. More than half of women with measurable disease taking LEE011 plus letrozole saw their tumor size shrink by at least 30% during treatment (overall response rate (ORR) in patients with measurable disease = 53% vs 37%, p=0.00028)1.

MedicalResearch.com Interview with: Chih-Hsin Yang MD PhD Department of Oncology National Taiwan University Hospital MedicalResearch.com: What is the background for this study? What are the main findings? Response: LUX-Lung 3 and LUX-Lung 6 are multicenter, randomized, open-label, Phase III trials of afatinib versus chemotherapy (pemetrexed / cisplatin and gemcitabine / cisplatin, respectively) as first-line treatment for patients with EGFR mutation-positive, advanced and metastatic non-small-cell lung cancer (NSCLC). Both trials met their primary endpoint of PFS with afatinib significantly delaying tumor growth when compared to standard chemotherapy. A post-hoc analysis of the studies was conducted to look at the incidence and severity of common adverse events (AEs) before and after afatinib dose reduction and the PFS was compared between patients who dose reduced within the first 6 months of treatment and those who did not. The results showed dose reductions were associated with decreases in the incidence and severity of treatment-related AEs, while median progression-free survival (PFS) was similar in patients who dose-reduced within the first six months of treatment versus those who did not (LUX-Lung 3, 11.3 vs 11 months; LUX-Lung 6, 12.3 vs 11 months).

MedicalResearch.com Interview with: Roger M. Nitsch, MD Professor and Director Institute for Regenerative Medicine · IREM University of Zurich Campus Schlieren Switzerland MedicalResearch.com: What is the background for this study? What are the main findings? Response: The main finding is that treatment with aducanumab resulted in an unprecedented reduction of brain amyloid plaques in patients with Alzheimer's disease.  The removal of amyloid from patients brains were both dose- and time-dependent.  We also observed initial hints for stabilized brain functions in patients receiving aducanumab.  In contrast, patients in the placebo group continued to declined as usual in this stage of Alzheimer's disease. The main safety finding in 22% of all treated patients was ARIA - an Amyloid-Related Imaging Abnormality - suggestive of fluid shifts in the brains. In most cases, ARIA occurred in the absence of clinical signs and resolved spontaneously.  In one third of the ARIA cases, patients experienced transient headaches.  None of the patients had to hospitalized because of ARIA.

MedicalResearch.com Interview with: Dr Charles Akle, Chairman and Linda Summerton, CEO Immodulon Therapeutics Short Hills, NJ 07078 and London, UKDr Charles Akle, Chairman and Dr. Linda Summerton, CEO Immodulon Therapeutics Short Hills, NJ 07078 and London, UK MedicalResearch.com: What is the background for Immodulon? Would you tell us a little about Dr. Charles Akle? Response: Immodulon was established in November 2007. The founder and Chairman, Dr Charles Akle, was a Harley Street surgeon and pioneer of keyhole surgery who established Immodulon with the financial support of a former patient. His interest in immunology led him to the potential of cancer immunotherapy long before the term “immuno-oncology” was coined and when skepticism, rather than optimism was the norm. His ambition from the start was to develop an affordable immunotherapy treatment that would transform the way that cancer is treated in the world today. Since then, Immodulon has become a leading, independent biopharmaceutical company with one of the longest running research projects into how to harness the power of the immune system in treating cancer. It also has its own R&D and manufacturing capability in Lyon, France. The wider Immodulon senior team has extensive experience of bringing drugs to market and includes Dr James Shannon and Dr Jean Pierre Bizzari. (more…)

MedicalResearch.com Interview with: Dirk Huebner, MD Senior Medical Director Oncology Therapeutic Area Unit Takeda Pharmaceutical Company MedicalResearch.com: What is the background for this study? What are the main findings? Response: Cutaneous lymphomas are a category of non-Hodgkin lymphoma that primarily involve the skin. Cutaneous T-cell lymphoma, also known as CTCL, is the most common type of cutaneous lymphoma and typically presents with red, scaly patches or thickened plaques of skin that often mimic eczema or chronic dermatitis. ADCETRIS® (brentuximab vedotin) is an antibody-drug conjugate directed to CD30, which is expressed on skin lesions in approximately 50 percent of patients with CTCL. The Phase 3 ALCANZA trial compared the use of single-agent ADCETRIS to a control arm of investigator’s choice of standard therapies, methotrexate or bexarotene, in 131 patients with CD30-expressing CTCL who received prior systemic or radiation therapy. The study met its primary endpoint, demonstrating a highly statistically significant improvement in the rate of objective response lasting at least four months (ORR4). The ORR4 was 56.3 percent in the ADCETRIS arm compared to 12.5 percent in the control arm. (more…)

MedicalResearch.com Interview with: Felix Garzon, MD, PhD Senior Vice President Head of Clinical Development Actinium Pharmaceuticals, Inc. New York, NY 10016 MedicalResearch.com: What is the background for this study? What is goal of this Study? Response: Iomab-B (“Iomab”) was developed at the Fred Hutchinson Cancer Research Center (“the Hutch”) in Seattle, Washington. The Hutch is a pioneer in the field of bone marrow transplantation (BMT) having 3 Nobel Prizes and doctors there performed some of the first transplants for leukemia patients. Iomab-B is intended to be an induction and conditioning agent prior to a BMT for patients with relapsed or refractory Acute Myeloid Leukemia (AML) who are over the age of 55. BMT is the only potentially curative option for AML i.e. for this patient population that currently has a survival prognosis of 2-6 months which means that if Iomab-B is successful it would create a new market segment and offer patients a great clinical benefit and a hope for a cure. Actinium Pharmaceuticals licensed Iomab from the Hutch in 2012 and prior to us licensing Iomab, it had been studied in almost 300 patients in several phase 1 and phase 2 clinical trials in an array of blood cancers, both leukemias and lymphomas. Actinium is now the sponsor of a pivotal phase 3 trial for Iomab-B to study its use as an induction and conditioning agent prior to a bone marrow transplantation in patients with relapsed or refractory AML who are over the age of 55. This trial, which we have named the SIERRA (Study of Iomab-B in Elderly Relapsed or Refractory AML) trial, started at the end of June 2016 and we expect to enroll 150 patients by the end of 2017. The primary endpoint of the SIERRA trial is durable complete remissions (dCR) of 6 months. The study arm will consist of Iomab-B administration followed by a  bone marrow transplantation, patients will be evaluated for dCR at 6 months after engraftment, which will be assessed at day 28 or day 56. The control arm of the study will be physician’s choice of chemotherapy and if the patient is able to achieve a complete remission (CR) they may receive a BMT or some other form of treatment with curative intent. The study is designed to evaluate if the study arm of Iomab-B and a BMT can double the dCR rate of the control arm, which is designed to replicate the current treatment regimen prior to a bone marrow transplantation .

Author Interviews, Gastrointestinal Disease, Gluten, Immunotherapy / 27.07.2016

MedicalResearch.com Interview with: Armin Alaedini, PhD Assistant Professor Department of Medicine & Institute of Human Nutrition Columbia University Medical Center New York, NY 10032 MedicalResearch.com: What is the background for this study? Response: It has been a mystery why some people experience a range of symptoms in response to the ingestion of wheat and related cereals, even though they do not have celiac disease (an autoimmune disorder) or wheat allergy. Both gastrointestinal (GI) symptoms, most commonly abdominal pain, diarrhea, and bloating, as well as extra-intestinal symptoms, such as fatigue, anxiety, depressed mood, and cognitive difficulties are reported by patients. The identity of the component(s) of wheat responsible for triggering the symptoms remains uncertain and it is not clear if gluten or non-gluten molecules are involved. There is evidence to indicate that wheat sensitivity also affects a subset of patients with irritable bowel syndrome (IBS), a common disorder. Despite the interest from the medical community and the general public, the causes and mechanism of the associated symptoms have remained unknown and no biomarkers are available to aid in the diagnosis of patients.

MedicalResearch.com Interview with: Ganesh Raghu, M.D. FACP, FCCP Professor of Medicine Division of Pulmonary and Critical Care Medicine and Director of Center for Interstitial Lung Diseases Director, Interstitial Lung Disease/Sarcoid/Pulmonary Fibrosis Program University of Washington Medical Center Seattle, Washington MedicalResearch.com: What is the background for this study? Response: This is a new post-hoc analysis of the Phase III INPULSIS trials, including a total of 1,061 patients with idiopathic pulmonary fibrosis (IPF), which has been published in the American Journal of Respiratory and Critical Care Medicine. As background, achieving an accurate diagnosis of IPF in clinical practice is very complex and challenging. Physicians use an imaging technique called high resolution computed tomography (HRCT) to help them identify the presence of scarring (fibrosis) and, specifically, the presence of usual interstitial pneumonia (UIP) pattern in the lungs. The radiological changes called "honeycombing" are the key feature of the UIP pattern visible on HRCT and the pattern of UIP is the hallmark of the fibrosis in patients with IPF. In the absence of definitive UIP pattern on HRCT images of the lungs, the diagnosis of  idiopathic pulmonary fibrosis requires the microscopic features of UIP in the surgical lung biopsy (SLB) based on current guidelines for diagnosis of IPF. However, it can be challenging to confirm that scarring in the absence of honeycombing on HRCT meets the strict guideline criteria for a definitive diagnosis of IPF. For a large group of patients who do not receive a confirmed diagnosis of IPF according to guidelines, including those not eligible for surgical lung biopsy, the clinical course of their condition and the effectiveness of  idiopathic pulmonary fibrosis treatment remains unknown. Therefore, investigations into the behavior of the disease across diagnostic subgroups are important. (more…)
Author Interviews, Immunotherapy, Prostate Cancer / 16.07.2016

MedicalResearch.com Interview with: Julie Graff, M.D. Oncologist specializing in prostate cancer Knight Cancer Institute Oregon Health & Science University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Men with metastatic prostate cancer that is not responding to second-line androgen receptor blockade (such as enzalutamide) have a very limited life expectancy. We found that adding immunotherapy to enzalutamide in men whose prostate cancer is no longer responding to enzalutamide could exert a very strong anti-cancer effect. Previous experience with this type of immunotherapy in prostate cancer patients suggested this type immunotherapy does not work in patients with prostate cancer. What we have found will lead to more studies of this agent. (more…)

MedicalResearch.com Interview with: Professor Frances Balkwill OBE, FMedSci Lead, Centre for Cancer and Inflammation Barts Cancer Institute Queen Mary University of London London MedicalResearch.com: What is the background for this study? Prof. Balkwill: We wanted to find out if chemotherapy altered patients immune system especially the immune cells that co-exist with cancer cells in tumors. We studied women with ovarian cancer who often receive chemotherapy after diagnosis but before surgery. This meant, at least in some of them, we could study a biopsy taken before treatment began and also a biopsy taken during the operation. (more…)

Dr. Ferris: Investigators at the University of Pittsburgh Cancer Institute<http://upci.upmc.edu/> (UPCI) co-led CheckMate-141<https://clinicaltrials.gov/ct2/show/NCT02105636> a large, randomized international phase III clinical trial that enrolled 361 patients with recurrent or metastatic head and neck squamous cell carcinoma who had not responded to platinum-based chemotherapy, a rapidly progressing form of the disease with an especially poor prognosis. Patients were randomized to receive either nivolumab or a single type of standard chemotherapy until tumor progression was observed. Nivolumab, which belongs to a class of drugs known as immunotherapeutics, enables the body’s immune system to destroy cancer cells. It currently is approved to treat certain types of cancers, including melanoma and lung cancer. The nivolumab group achieved better outcomes than the standard chemotherapy group by all accounts. After 12 months, 36 percent of the nivolumab group was alive, compared to just 17 percent of the standard chemotherapy group. Nivolumab treatment also doubled the number of patients whose tumors shrunk, and the number whose disease had not progressed after six months of treatment. Importantly, these benefits were achieved with just one-third the rate of serious adverse events reported in the standard chemotherapy group. In addition, on average, patients receiving nivolumab reported that their quality of life remained stable or improved throughout the study, while those in the chemotherapy group reported a decline. The new trial was considered so successful that it was stopped early to allow patients in the comparison group to receive the new drug. (more…)
