Difference in CRISS scores over trial period between JBT-101 and placebo groups was significant (p = 0.044); Median CRISS score at week 16 reached 33% in JBT-101 group versus 0% in placebo group; Management to host conference call and webcast today at 8:30 a.m. EST NORWOOD, MA--(Marketwired - November 14, 2016) - Corbus Pharmaceuticals Holdings, Inc. ( : CRBP) ("Corbus" or the "Company"), a clinical stage drug development company targeting rare, chronic, serious inflammatory and fibrotic diseases, today announced positive topline results from its Phase 2 study evaluating Resunab ("JBT-101") for the treatment of diffuse cutaneous systemic sclerosis ("systemic sclerosis"). JBT-101 out-performed placebo in the American College of Rheumatology (ACR) Combined Response Index in diffuse cutaneous Systemic Sclerosis (CRISS) score, reaching 33% at week 16, versus 0% for placebo. The higher the CRISS score the greater the improvement; a CRISS score ≥ 20% (CRISS20) can be considered a medically meaningful improvement. The difference in CRISS scores between JBT-101 and placebo groups over the trial period was significant (p = 0.044). Differences in categorical levels of CRISS responses and changes from baseline in the five individual domains of the CRISS score also supported clinical benefit of JBT-101. "This is the first double-blind, randomized, placebo controlled trial in diffuse cutaneous systemic sclerosis to demonstrate a clinical benefit using the CRISS as an endpoint, with a drug that was safe and well tolerated in the trial. These results bring hope to patients and their physicians that JBT-101 may be an effective drug for systemic sclerosis where currently there are no proven treatments," said Principal Investigator Robert Spiera, M.D., Director of the Vasculitis and Scleroderma Program at the Hospital for Special Surgery, Weill Cornell Medical College in New York City. Corbus management will host a conference call and live webcast, with accompanying presentation slides, for investors, analysts and other interested parties today at 8:30 a.m. ET (details below). "The positive results of this study exceed our expectations and validate the unique mechanism of action of JBT-101. Our drug previously demonstrated clear and consistent evidence of activity in cellular and animal models as well as in healthy volunteers, repeatedly showing that its engagement with the CB2 receptor and its activation of inflammatory resolution translates into a potent effect on inflammation and fibrosis. With the data from this Phase 2 study, we now show that this mechanism of action provided clinical benefit in patients with systemic sclerosis in this trial," stated Yuval Cohen, Ph.D., Chief Executive Officer of the Company. "We look forward to the next stages in the clinical development of this drug. We are sincerely grateful to the patients, their physicians and the clinical staff who participated in this trial." The multi-center, double-blind, randomized, placebo-controlled Phase 2 study evaluated JBT-101's clinical benefit and safety in 27 subjects who received JBT-101 and 15 who received placebo. Subjects had disease duration up to 6 years and were allowed to receive stable doses of immunosuppressive drugs during this study. Subjects were randomized (2 to 1 overall JBT-101 to placebo ratio) to receive JBT-101 for the first four weeks at 5 mg once a day (n = 9), 20 mg once a day (n = 9), or 20 mg twice a day (n = 9) or placebo for the first four weeks, then all JBT-101 subjects received 20 mg twice a day for the next 8 weeks. All subjects were followed off study drug from weeks 13 through 16. The primary efficacy objective was to evaluate clinical benefit in all subjects who received JBT-101 versus subjects who received placebo using the ACR CRISS score, a measure of improvement in systemic sclerosis. The CRISS is an exponentially weighted algorithm of change from baseline that includes the modified Rodnan skin score (mRSS), a measure of skin thickening, physician global assessment (MDGA), patient global assessment (PtGA), and Health Assessment Questionnaire - Disability Index (HAQ-DI), and forced vital capacity (FVC). Results: The median (25th percentile, 75th percentile) CRISS scores for the combined JBT-101 group and the placebo group at Weeks 4, 8, 12, and 16 are provided in the table below. The difference in CRISS scores between JBT-101 and placebo groups over the trial period was significant (p = 0.044), 1-sided mixed model repeated measures using rank transformed data. Results of secondary efficacy outcome measures supported the finding of clinical benefit of JBT-101, including numerical superiority of JBT-101 in each of the five domains of the CRISS score, with divergence starting early at Week 4 or Week 8. There were no serious, severe, or unexpected adverse events related to JBT-101. One of 27 subjects (3.7% of subjects) who received JBT-101 withdrew from the study for an adverse event which was moderate dizziness. "We are excited about these positive clinical outcomes in the JBT-101 group in this study, especially given its short duration and relatively small number of diverse systemic sclerosis subjects," stated Barbara White, M.D., Chief Medical Officer of the Company. "With these clinical data and findings of acceptable safety and tolerability, we plan to reach out to regulatory authorities to confirm the next steps forward." The primary treatment period has been completed and subjects are now enrolled in a one- year open label extension to obtain data on long-term safety and durability of response. Corbus received approval for an open-label extension to its Phase 2 clinical study of JBT-101 for systemic sclerosis from the U.S. Food and Drug Administration ("FDA") in April of 2016. The open-label extension enables all the participants in the study to receive JBT-101 for an additional 12 months. JBT-101 was granted Orphan Drug Designation and Fast Track status for the treatment of systemic sclerosis by the FDA in 2015. For more information on the Phase 2 study with JBT-101 for the treatment of systemic sclerosis, please visit ClinicalTrials.gov and reference Identifier NCT02465437. Conference Call and Webcast Information Corbus management will host a conference call for investors, analysts and other interested parties today, November 14, 2016 at 8:30 am ET to discuss the topline data from the Phase 2 Study evaluating JBT-101 for the treatment of systemic sclerosis. The conference call and live webcast will be accompanied by presentation slides. To participate in the call, please dial (877) 407-3978 (domestic) or (412) 902-0039 (international). The live webcast and accompanying slides will be accessible on the Events page of the Investors section of Corbus website, www.corbuspharma.com, and will be archived for 60 days. About Systemic Sclerosis Systemic sclerosis is a chronic, systemic autoimmune rheumatic disease with an unclear etiology. Systemic sclerosis affects approximately 90,000 people in the United States and Europe, with disease onset typically in mid-life. About 80 percent of systemic sclerosis patients are women. The disease process in systemic sclerosis includes activation of the immune system, with damage to small blood vessels and fibrosis of the skin on internal organs, including lungs, heart, kidneys, gastrointestinal tract and musculoskeletal system. Chronic disease burden, morbidity and mortality are significant. Cardiopulmonary disease is the major cause of death in systemic sclerosis. Immunosuppressive medications such as oral corticosteroids, methotrexate, cyclophosphamide, and mycophenolate mofetil are used to treat patients with more severe signs and symptoms of disease. Currently, there are no FDA-approved treatments specifically indicated for the treatment of systemic sclerosis, other than pulmonary artery hypertension secondary to connective tissue diseases such as systemic sclerosis. About Resunab ("JBT-101") JBT-101 is a novel synthetic oral endocannabinoid-mimetic drug that preferentially binds to the CB2 receptor expressed on activated immune cells and fibroblasts. CB2 activation triggers endogenous pathways that resolve inflammation and halt fibrosis. Preclinical and Phase 1 studies have shown JBT-101 to have a favorable safety, tolerability and pharmacokinetic profile. It has also demonstrated promising potency in preclinical models of inflammation and fibrosis. JBT-101 is designed to trigger the production of "Specialized Pro-resolving Lipid Mediators" that activate an endogenous cascade responsible for the resolution of inflammation and fibrosis, while reducing production of multiple inflammatory mediators. JBT-101 has direct effects on fibroblasts to halt tissue scarring. In effect, JBT-101 triggers endogenous pathways to turn "off" chronic inflammation and fibrotic processes, without causing immunosuppression. About Corbus Corbus Pharmaceuticals Holdings, Inc. is a clinical stage pharmaceutical company focused on the development and commercialization of novel therapeutics to treat rare, chronic, and serious inflammatory and fibrotic diseases. Our lead product candidate, JBT-101, is a novel synthetic oral endocannabinoid-mimetic drug designed to resolve chronic inflammation, and fibrotic processes. JBT-101 is currently in Phase 2 clinical studies for the treatment of cystic fibrosis, diffuse cutaneous systemic sclerosis and skin-predominant dermatomyositis, with a fourth Phase 2 trial in systemic lupus erythematosus planned to commence during the first half of 2017.

Whipple's disease is a chronic, systemic infection caused by Tropheryma whipplei. Gene amplification, isolation and DNA sequencing of T whipplei have extended our knowledge of this pathogen, which is now recognised as a ubiquitous commensal bacterium. The spectrum of signs associated with T whipplei has now been extended beyond the classic form, which affects middle-aged men, and begins with recurrent arthritis followed several years later by digestive problems associated with other diverse clinical signs. Children may present an acute primary infection, but only a small number of people with a genetic predisposition subsequently develop authentic Whipple's disease. This bacterium may also cause localised chronic infections with no intestinal symptoms: endocarditis, central nervous system involvement, arthritis, uveitis and spondylodiscitis. An impaired TH1 immune response is seen. T whipplei replication in vitro is dependent on interleukin 16 and is accompanied by the apoptosis of host cells, facilitating dissemination of the bacterium. In patients with arthritis, PCR with samples of joint fluid, saliva and stools has become the preferred examination for diagnosis. Immunohistochemical staining is also widely used for diagnosis. Treatment is based on recent microbiological data, but an immune reconstitution syndrome and recurrence remain possible. The future development of serological tests for diagnosis and the generalisation of antigen detection by immunohistochemistry should make it possible to obtain a diagnosis earlier and thus to decrease the morbidity, and perhaps also the mortality, associated with this curable disease which may, nonetheless, be fatal if diagnosed late or in an extensive systemic form.

Objective: To date, there are no reliable data regarding the actual treatment received by women with refractory obstetric antiphospholipid syndrome (OAPS). The aim of this study was to assess current clinical evidence and new trends in the treatment of refractory OAPS. Methods: A non-systematic but comprehensive literature search using relevant keywords was made to identify relevant articles published in English from different computerized databases: PubMed (Medline), Google Scholar electronic database search and The Cochrane Library, from January 2000 to March 2012. Studies on the treatment of poor obstetric outcomes in women with OAPS were included. Prospective randomized clinical trials, cohort studies, reviews, systematic reviews and meta-analysis were retrieved. Results: A total of 130 articles were finally selected for this review, including 17 randomized clinical trials and four meta-analyses. The majority of articles were non-randomized original papers and basic and clinical reviews. Conclusion: Up to 20% of women with OAPS do not receive the currently recommended therapeutic regimen. Unfortunately, well-designed studies regarding the usefulness of new drugs in refractory OAPS are scarce. Hydroxychloroquine and low-dose prednisolone appear to be useful when added to standard therapy. Current data do not support the use of intravenous immunoglobulins in this field. The role played by double antiaggregant therapy, fondaparinux, vitamin D, pentoxifylline and TNF-targeted therapies should be tested in well-designed studies. © The Author(s), 2012.

Patients with autoimmune rheumatic diseases are more susceptible to infectious complications during the course of their disease. The introduction of biologics has been a major achievement in treating these diseases, but an increased risk of infection associated with these therapies has become evident. Some infections can be prevented by vaccination and it is clearly worthwhile considering which immunisations would be sensible and practicable for these patients. To date no formal specific recommendations for patients on biologics have been published. A search was made of Medline (via PubMed) from 1970 to January 2014 to provide results. This review aims to provide a systematic analysis of the data about vaccines and biologics and considers recommendations for vaccination in adult patients with autoimmune rheumatic diseases treated with biologics.


The LupusQoL© questionnaire is a disease-specific health related quality of life (HRQOL) instrument for adults with systemic lupus erythematosus (SLE). The Short Form-36 (SF-36) is a generic instrument that captures the physical, psychological, and social impact. We conducted a descriptive study of women aged ≥ 18 years attending our Lupus Clinic. HRQOL was assessed by applying the LupusQoL© and SF-36. Lupus activity was measured using the Mexican Systemic Lupus Erythematosus Disease Activity Index (Mex-SLEDAI) and chronic damage using the Systemic Lupus Collaborative Clinics Damage Index (SDI). Data were analyzed using descriptive statistics, the chi-square test and Pearson's product moment correlation coefficient. A total of 127 patients were included with a mean age of 40.5 ± 12.6 years. The mean disease duration was 8.2 ± 5.6 years, the mean disease activity score was 2.4 ± 3.0, and the mean SDI score 0.77 ± 1.06. The mean SF-36 score was 58.1 ± 21.1 and the mean LupusQoL© score was 69 ± 22.7. The correlation between global scores of the SF-36 and LupusQoL© was rho = 0.73 (p < 0.001). The correlation between lupus disease activity and the SF-36 and the LupusQoL© was -0.26 (p = 0.003) and -0.25 (p = 0.004), respectively. The correlation between the SDI and the SF-36 and the LupusQoL© was -0.28 (p = 0.001) and -0.38 (p < 0.0001), respectively. In conclusions: both LupusQoL© and SF-36 were useful instruments in assessing HRQOL in Mexican lupus female patients. The usefulness of the LupusQoL© should be evaluated in lupus patients with moderate to severe disease activity.


The aim of this study was to assess the effects of continuous positive airway pressure (CPAP) on arterial stiffness, central blood pressure, and reflected pulse wave characteristics in patients with severe obstructive sleep apnea (OSA) and stage 2-3 arterial hypertension. Forty-four patients with hypertension and severe OSA (apnea/hypopnea index > 30) received stepped dose titration of antihypertensive treatment, consisting of valsartan 160 mg + amlodipine 5-10 mg + hydrochlorothiazide 25 mg. CPAP therapy was added after 3 weeks of continuous antihypertensive treatment with BP < 140/90 mmHg or after adjusting triple treatment in patients with resistant arterial hypertension. The patients were randomized to effective CPAP (4-15 mm H2O) or placebo CPAP (pressure 4 mm H2O) for three weeks, then crossed over to the alternative treatment in a single-blind manner. Office blood pressure (BP), ambulatory BP monitoring, ambulatory arterial stiffness index (AASI), aortic BP, carotid-femoral pulse wave velocity (cfPWV), and systolic wave augmentation index were measured using a Sphygmocor® device at baseline, after antihypertensive treatment, placebo CPAP, and effective CPAP. Baseline cfPWV was above the normal range in 94% of patients. After reaching target BP, the cfPWV decreased by 1.9 ± 1.0 msec (P = 0.007). Effective CPAP achieved a further cfPWV reduction of 0.7 msec (P = 0.03). Increased arterial stiffness (pulse wave velocity > 12 msec) persisted in 35% of patients on antihypertensive treatment and effective CPAP, in 56% of patients on antihypertensive treatment alone, and in 53% of patients on placebo CPAP. Only the combination of antihypertensive treatment with effective CPAP achieved a significant reduction in augmentation index and AASI, along with a further reduction in aortic and brachial BP. Effective CPAP for 3 weeks resulted in a significant additional decrease in office BP, ambulatory BP monitoring, central BP, and augmentation index, together with an improvement in arterial stiffness parameters, ie, cfPWV and AASI, in a group of hypertensive patients with OSA.

PURPOSE OF REVIEW: The role of innate immunity in systemic lupus erythematosus (SLE) has been a rapidly expanding area of research over the last decade. Included in this rubric is the concept that activation of the inflammasome, a molecular complex that activates caspase-1 and in turn the cytokines IL-1β and IL-18, is important in lupus pathogenesis. This review will summarize the recent discoveries exploring the role of the inflammasome machinery in SLE. RECENT FINDINGS: Immune complexes can activate the NLRP3 inflammasome, and SLE-derived macrophages are hyper-responsive to innate immune stimuli, leading to enhanced activation of the inflammasome and production of inflammatory cytokines. Work in several murine models suggests an important role for the NLRP3 inflammasome in mediating lupus nephritis. Caspase-1, the central enzyme of the inflammasome, is essential for the development of type I interferon responses, autoantibody production, and nephritis in the pristane model of lupus. The absence of melanoma 2 inflammasome may have protective and pathogenic roles in SLE. SUMMARY: Recent evidence suggests that the inflammasome machinery is dysregulated in SLE, plays an important role in promotion of organ damage, and may mediate cross-talk between environmental triggers and the development of lupus. Further research should focus on whether inhibition of inflammasome components may serve as a viable target for therapeutic development in SLE. © 2014 Wolters Kluwer Health | Lippincott Williams & Wilkins.

This review analyses whether skin temperature represents ambient temperature and serves as a feedforward signal for the thermoregulation system, or whether it is one of the body's temperatures and provides feedback. The body is covered mostly by hairy (non-glabrous) skin, which is typically insulated from the environment (with clothes in humans and with fur in non-human mammals). Thermal signals from hairy skin represent a temperature of the insulated superficial layer of the body and provide feedback to the thermoregulation system. It is explained that this feedback is auxiliary, both negative and positive, and that it reduces the system's response time and load error. Non-hairy (glabrous) skin covers specialized heat-exchange organs (e.g. the hand), which are also used to explore the environment. In thermoregulation, these organs are primarily effectors. Their main thermosensory-related role is to assess local temperatures of objects explored; these local temperatures are feedforward signals for various behaviours. Non-hairy skin also contributes to the feedback for thermoregulation, but this contribution is limited. Autonomic (physiological) thermoregulation does not use feedforward signals. Thermoregulatory behaviours use both feedback and feedforward signals. Implications of these principles to thermopharmacology, a new approach to achieving biological effects by blocking temperature signals with drugs, are discussed. © 2014 The Author.

We propose to develop a comprehensive mixed-signal design solution with an IP infrastructure, design methodology and design automation tools to enable the use of regular fabrics and mask re-use. The IP infrastructure will consist of metal-reconfigurable analog/RF templates built on top of the existing PDF Solutions’ pdBrixTM solution. The design methodology will allow designers to achieve performance on par with custom mixed-signal design at a fraction of the mask and NRE cost. The design tools will integrate the IP infrastructure into the existing Electronic Design Automation (EDA) framework and provide some missing functionality for maximum mask re-use.
