Background and Aims:In the treatment of chronic hepatitis B (CHB) infection, stimulation of innate immunity may lead to hepatitis B virus (HBV) cure. Alpha‐kinase 1 (ALPK1) is a pattern recognition receptor (PRR) that activates the NF‐κB pathway and stimulates innate immunity. Here we characterized the preclinical anti‐HBV efficacy of DF‐006, an orally active agonist of ALPK1 currently in clinical development for CHB.Approach and Results:In adeno‐associated virus (AAV)‐HBV mouse models and primary human hepatocytes (PHHs) infected with HBV, we evaluated the antiviral efficacy of DF‐006. In the mouse models, DF‐006 rapidly reduced serum HBV DNA, hepatitis B surface antigen, and hepatitis B e antigen levels using doses as low as 0.08 μg/kg, 1 μg/kg, and 5 μg/kg, respectively. DF‐006 in combination with the HBV nucleoside reverse transcriptase inhibitor, entecavir, further reduced HBV DNA. Antiviral efficacy in mice was associated with an increase in immune cell infiltration and decrease of hepatitis B core antigen, encapsidated pregenomic RNA, and covalently closed circular DNA in liver. At subnanomolar concentrations, DF‐006 also showed anti‐HBV efficacy in PHH with significant reductions of HBV DNA. Following dosing with DF‐006, there was upregulation of NF‐κB‐targeted genes that are involved in innate immunity.Conclusion:DF‐006 was efficacious in mouse and PHH models of HBV without any indications of overt toxicity. In mice, DF‐006 localized primarily to the liver where it potently activated innate immunity. The transcriptional response in mouse liver provides insights into mechanisms that mediate anti‐HBV efficacy by DF‐006.

The prevalence of indoor allergens in the Baltimore area: House dust-mite and animal-dander antigens measured by immunochemical techniques

Article

作者: B. Schwartz ; P.S. Norman ; H. Løwenstein ; M. Newton ; P. Lind

Mattress dust samples from 42 homes in Baltimore, Md., were analyzed by ELISA and rocket immunoelectrophoresis (RIE) for major excrement allergens (P1 [equal to Dp 42], Df 6, and Dm 6) of house dust mites, Dermatophagoides pteronyssinus, D. farinae, and D. microceras, by RIE for cat major epithelial allergen (cat Ag 1) and horse major epithelial antigen (horse Ag 11), and by counter-current immunoelectrophoresis (CCIE) for cat and dog antigens. Dp 42 was detected by ELISA in 24 samples (57%) and Df 6 in 39 samples (92%). All samples were negative to Dm 6. Recorded levels varied from 50 ng of allergen per gram of dust (detection limit) to 15,000 ng/gm. A combined content of Dp 42 and Df 6 greater than 700 ng/gm was associated with a positive reaction in RIE. Concentrations of Dp 42 and Df 6 did not correlate (rS = 0.21; p greater than 0.05). Cat and dog antigens were frequently detected by CCIE (77% and 63%, respectively). CCIE titer to cat correlated well with quantitation of cat Ag 1 by RIE (p less than 0.01). Horse antigen was detected in few homes (5%). None of the specific allergen determinations correlated with levels of human serum albumin determined by RIE.

Relationship between Specific Circulating IgE, Basophil Cell-Bound IgE and Histamine Release Induced by Purified Allergens of Dermatophagoides Farinae

Article

作者: Weyer, A. ; Dandeu, J.P. ; Le Mao, J. ; Rabillon, J. ; David, B.

In this study we analysed the presence and proportions of IgE specific for Df 6 and Df 11 two purified allergens of Dermatophagoides farinae. The characterisation of serum IgE and cell-bound IgE for 3 D. farinae-sensitive patients were performed by CRIE, RAST and PRIST assays. Furthermore the basophils from these same patients were studied by histamine release assays in the presence of Df 6 and Df 11. All the individual patient’s cell and serum IgE samples displayed the presence of IgE antibodies specific for Df 6 and Df 11 but the relative quantities of the IgE for these two specificities were characteristic of each patient. The ratios (Specific IgE for Df 11): (Specific IgE for Df 6) (ratio 11:6) were similar in the serum and on the cells for an individual patient. As judged by histamine release assays, the basophil sensitivities towards Df 6 and Df 11 were very different from one atopic patient to another. Moreover cell sensitivities reflected the proportion of Df 6- and Df 11-specific IgE antibodies found in the serum and in the cell eluate.

Drug Farm Announces anti-HBV immunomodulator, DF-006 is Accepted as a Late-Breaking Presentation at the 2024 European Association for the Study of the Liver Conference

GUILFORD, Conn.--(BUSINESS WIRE)-- Drug Farm, a private biotechnology company utilizing genetics and artificial intelligence technologies to discover and develop innovative, immune-modulating therapies, today announced that the chronic hepatitis B patient data from their Phase 1b trial (ACTRN12621000592842) was accepted as a late breaking poster presentation at the 2024 European Association for the Study of the Liver (EASL) conference that will be held in Milan, Italy between 05 June 2024 to 08 June 2024. Poster #LB46 Title: A phase 1, double-blinded, randomized, placebo-controlled, multicenter global study evaluating the safety, tolerability, and antiviral activity of DF-006 in chronic hepatitis B, virologically-suppressed patients. Date: 05 June 2024 Time: 8.30 am – 5.00 pm CET DF-006 is a first-in-class, orally administered ALPK1 agonist immunomodulator that potently stimulates local, innate immunity in the liver1. DF-006 has successfully completed single and multiple ascending dose (MAD) evaluation in healthy volunteers, and MAD evaluation in virologically suppressed HBeAg negative chronic hepatitis B (CHB) patients. “There remains no effective cure for CHB. DF-006 has a novel mechanism of action that is capable of stimulating the body’s own immune system to help clear the infection. As an oral drug administered once weekly, DF-006 has the potential to be the immunomodulator of choice in combination HBV cure regimens”, said Dr. Ed Gane, Professor of Medicine at the University of Auckland, New Zealand and Chief Hepatologist, Transplant Physician, and Deputy Director of the New Zealand Liver Transplant Unit at Auckland City Hospital. “DF-006 has demonstrated potent antiviral responses in preclinical studies, including inhibition of cccDNA and recruitment of T-cells. The data from this trial study now provides clinical support for a drug with a novel mechanism of action that could be used to help cure CHB patients”, said Drug Farm’s Chief Medical Officer, Dr. Jeysen Yogaratnam.
