Kinase Inhibitor, Janus

Kinase Inhibitors, Janus: A class of small-molecule compounds that target and inhibit the activity of Janus kinases (JAKs), a family of receptor-associated tyrosine kinases involved in various cellular processes.
Janus kinase inhibitors have emerged as important therapeutic agents for the treatment of inflammatory and autoimmune disorders, as well as certain types of cancer.
These compounds work by blocking the JAK-STAT signaling pathway, which regulates gene expression and immune response.
Researching and optimizing Janus kinase inhibitors is a crucial area of study for developing effective treatments for a range of medical conditions.

Quantitative reverse-transcriptase–polymerase-chain-reaction, cytokine, protein, and gene-expression analyses were performed according to standard procedures and are described in the Supplementary Appendix, available with the full text of this article at NEJM.org. Constructs of mutated TMEM173 (V147L, N154S, V155M, and V155R) and nonmutated TMEM173 were transfected into a STING-negative cell line (HEK293T cells) and stimulated with the STING ligand cyclic guanosine monophosphate–adenosine monophosphate (cGAMP [3′3′-cGAMP, Invivogen]).
When possible, we obtained blood and tissue samples from the study participants to assess activation and cell death of peripheral-blood cells. Tissue blocks from skin biopsies (in five patients), samples from lung biopsies (in two), and slides of a sample from a previous muscle biopsy (in one) were obtained and analyzed. Dermal fibroblast lines were obtained from two patients, four healthy controls, and three controls with the CANDLE syndrome. Primary endothelial cells were stimulated with the STING ligand cGAMP.
CD4 T cells and CD19 B cells from Patients 4 and 6 were treated for 4 hours with one of three Janus kinase (JAK) inhibitors — tofacitinib (1 μM), ruxolitinib (100 nM), or baricitinib (200 nM) — to assess their ability to block phosphorylation of the signal transducers and activators of transcription 1 (STAT1) and 3 (STAT3). Fibroblasts from Patient 1 and healthy controls were stimulated with 500 ng of cGAMP per milliliter and were also treated with 0.1 or 1.0 μM tofacitinib. We assayed the suppression of the gene encoding interferon-β (IFNB1) and other interferon-induced genes (CXCL10, MX1, and OAS3). Additional details are provided in the Supplementary Appendix.

The generation of the GFAP-GFP mouse used in this study has been described previously (Zhou et al., 1997) and CD1 mice were obtained from Charles River Labs (Wilmington, MA). All mouse colonies were maintained in the animal facility of Children’s National Medical Center, and all animal procedures complied with the guidelines of the National Institute of Health, and with the Children’s Research Institute Institutional Animal Care and Use Committee (IACUC) guidelines. Male mice were placed in a chamber containing 10.5 ± 0.5% O2 from P3 to P11 as previously described (Ment et al., 1998 ; Fagel et al., 2006 (link)). Strain-matched and age-matched animals reared in normal oxygen levels were used as controls (normoxia). For studies examining proliferation, BrdU (Sigma; 50μg per gram body weight) was administered 2hr prior to sacrifice. Mice were sacrificed at the given time point after hypoxia and perfused transcardially with phosphate buffered saline followed by 4% paraformaldehyde (PFA) and post fixed overnight in PFA followed by 20% glycerol and stored at 4°C. Treatment of mice with the JAK/STAT inhibitor AG490 has been previously described (Zhou et al., 2011 (link); Xu et al., 2011 ). Briefly, CD1 mice were treated with AG490 (10 mg/kg i.p.) or DMSO (control) twice daily (injections were ~8–10 hours apart) from P6 to P11. At P11 the white matter was carefully dissected out and lysed as described below, followed by Western blot analysis.

Patient information at the time of SDM implementation was retrospectively obtained from the medical records. The surveyed items were sex, age (years), age (<65 years/≥65 years), RA, multiple rheumatic diseases, disease duration (years), disease duration (<10/≥10 years), disease activity (active/inactive), number of drugs used (number), number of drugs used (<5/≥5), history of allergy or side effects, history of allergy or side effects due to biologics or Janus kinase inhibitor, biologics, or Janus kinase inhibitor usage history before SDM. Age was classified into two categories according to the World Health Organization (WHO). Disease duration was classified into two categories based on a previous report on RA (12 (link)). Disease activity was classified into two categories; patients with RA were categorized as inactive if they exhibited low disease activity or remission based on their DAS28-CRP value and as active if they exhibited moderate or high disease activity. Those with other rheumatic diseases were classified as inactive if clinically judged by a physician to be in remission or have low disease activity and as active if they were otherwise judged to have moderate or higher-intensity symptoms. The number of drugs used was classified into two categories based on a previous report on polypharmacy (13 (link)).
The influential values of patients regarding drug treatment were compiled from subjective data describing values chosen by patients during conversations between pharmacists and patients during SDM implementation. The values compiled were multiple selected and single selected from the five values: effectiveness, safety, economic, daily life (drug treatment burden on life), and others (such as route of administration, type of device).
The continuance rate of treatment 6 months after SDM and disease status (improvement, aggravation, and no change) were evaluated, with reasons including inadequate effectiveness, side effects, economic issues, daily life issues, and other issues among patients.
The details of the drug treatment changes selected after the implementation of SDM were tabulated. The results included changing the drugs, tight control, no change, drug use cessation, increased dosage, change in the route of administration, addition of an oral drug, oral drug cessation, reduced dosage, changes in oral drug, and shortening of the interval between doses.
Because SDM was performed in the usual clinical setting, the pharmacists were not blinded to the outcomes, such as the continuance rate of treatment.

The information described in each dimension was evaluated using the Greenacre inertia adjustment, and the categorical variables were plotted in two dimensions with the highest inertia (15 ). A K-means cluster analysis, a non-hierarchical cluster analysis identifying mutually exclusive clusters by calculating the quadratic Euclidean distance (coefficient of similarity) of the point categories (16 (link), 17 (link)), was necessary to objectively ascertain which values each of the patient background items related to or belonged to. The coordinates (object scores) of each of the dimensions 1 and 2 of each variable calculated by MCA were input to K-means cluster analysis and the categorical variables, including the values and the basic information of patient characteristics, were grouped (18 (link)). The cubic clustering criterion (CCC) was calculated with statistical software and used to determine the optimal number of clusters (19 , 20 (link)). After clustering each variable, density ellipses (α = 95%) for each cluster were shown to indicate the overlap between clusters and were overlaid with the MCA plot. Statistical analyses were performed using JMP Pro 16 software (SAS Institute Inc., Cary, NC, United States).

During the study period, the following treatments are prohibited: administration of a bDMARD, except tocilizumab, or JAK inhibitor, except for filgotinib; concomitant use of an immunosuppressant (azathioprine, cyclophosphamide, cyclosporine), csDMARD, or oral corticosteroids equivalent to more than 5 mg/day of prednisolone, in addition to intra-articular corticosteroid injections at joints, and nonsteroidal anti-inflammatory drug suppositories. During the study period, the dose of any oral nonsteroidal anti-inflammatory drug can be modified within the range of its approved doses in Japan.
