Ho Lee, Y, Gyu Song, G
Journal of clinical pharmacy and therapeutics. 2020;(4):674-681
Abstract
WHAT IS KNOWN AND OBJECTIVE Several clinical trials have attempted to evaluate the efficacy and safety of tofacitinib, baricitinib, upadacitinib, filgotinib and peficitinib as monotherapy in patients with active rheumatoid arthritis (RA), but their relative efficacy and safety as monotherapy remain unclear due to the lack of data from head-to-head comparison trials. The relative efficacy and safety of tofacitinib, baricitinib, upadacitinib, filgotinib and peficitinib as monotherapy for rheumatoid arthritis (RA) were assessed. METHODS We performed a Bayesian network meta-analysis to combine direct and indirect evidence from randomized controlled trials (RCTs) and examine the efficacy and safety of tofacitinib, baricitinib, upadacitinib, filgotinib and peficitinib as monotherapy relative to placebo in patients with RA. RESULTS AND DISCUSSION Five RCTs comprising 1547 patients met the inclusion criteria. Compared with placebo, tofacitinib, baricitinib, upadacitinib, filgotinib and peficitinib as monotherapy showed a significantly higher American College of Rheumatology 20% (ACR20) response rate. Peficitinib 150 mg monotherapy showed the highest ACR20 response rate (odds ratio, 17.24.39; 95% credible interval, 6.57-51.80). The ranking probability based on the surface under the cumulative ranking curve indicated that peficitinib 150 mg had the highest probability of being the best treatment for achieving the ACR20 response rate, followed by peficitinib 100 mg, filgotinib 200 mg, filgotinib 100 mg, tofacitinib 5 mg, upadacitinib 15 mg, baricitinib 4 mg and placebo. However, the number of patients who experienced serious adverse events did not differ significantly between the JAK inhibitors, except for tofacitinib 5 mg, and placebo. WHAT IS NEW AND CONCLUSION All five JAK inhibitors-tofacitinib, baricitinib, upadacitinib, filgotinib and peficitinib-were efficacious monotherapy interventions for active RA, and differences were noted in their efficacy and safety in monotherapy.

Puliafito, I, Russo, A, Sciacca, D, Puglisi, C, Giuffrida, D
Journal of medical case reports. 2020;(1):7
Abstract
BACKGROUND Pazopanib is a multitarget tyrosine kinase inhibitor used in the treatment of renal cancer and soft tissue sarcoma. Its use is commonly associated with a number of side effects, such as hemorrhagic diathesis, neutropenia, leukopenia, thrombocytopenia, nausea, vomiting, abdominal pain, increased serum aspartate aminotransferase, increased serum alanine aminotransferase, decreased serum glucose, increased serum bilirubin, decreased serum phosphate and magnesium, fatigue, hypertension, diarrhea, anorexia, proteinuria, and hypothyroidism. Abscesses of metastases caused by pazopanib administration are rarely reported in the literature. CASE PRESENTATION We report a case of abscesses of lung metastases related to pazopanib in a patient with metastatic renal cancer. The patient was a 53-year-old Caucasian man who developed abscesses of lung metastases during the first 3 months of treatment with pazopanib. The abscesses resolved after 1 month by stopping pazopanib and administering adequate antibiotic therapy. CONCLUSIONS We conclude that abscesses of metastases could be a rare side effect occurring during treatment with pazopanib in patients with renal cancer.

Abstract
BACKGROUND Fluoropyrimidine combined with oxaliplatin-based chemotherapy have become the first-line treatment for advanced colorectal cancer (CRC). Chinese herbal injections (CHIs), as an important part of TCM, have been widely applied as adjunctive treatments to chemotherapy in patients with advanced CRC. However, the efficacy of this combination therapy has not been evaluated comprehensively. METHODS We will conduct this systematic review and meta-analysis in accordance with the Preferred Reported Items for Systematic Review and Meta-analysis (PRISMA) guidelines. 7 databases will be searched for related randomized controlled trials (RCTs) from their inception to August 31, 2020: PubMed, Cochrane Library, EMBASE, China National Knowledge Infrastructure (CNKI), VIP Database for Chinese Technical Periodicals (VIP), SinoMED and Wanfang Database. Two researchers will perform study selection, data extraction, and assessment of risk of bias independently. The primary outcomes are the disease control rate (DCR) and the objective response rate (ORR), the secondary outcomes are progression-free survival (PFS), survival rate, quality of life (QoL) and adverse effects. Cochrane Review Manager (RevMan 5.3) software will be used to analyze the outcomes. RESULTS AND CONCLUSION This systematic review will evaluate the efficacy of CHIs and fluoropyrimidine and oxaliplatin-based chemotherapy for advanced CRC so as to provide valuable evidence to the application of CHIs in advanced CRC.

Abstract
Type 2 diabetes and dyslipidemia are diseases that collectively increase the risk of patients developing cardiovascular complications. Several incretin-based drugs are reported to improve lipid metabolism, and one of these medications, anagliptin, is a dipeptidyl peptidase-4 (DPP-4) inhibitor that has been shown to decrease serum triglyceride and low-density lipoproteins cholesterol. This study aimed to conduct an investigation into the effects of anagliptin on serum lipid profiles. This multicenter, open-label, randomized (1:1), parallel group study was designed to evaluate the effects of anagliptin on serum lipid profiles (triglycerides, lipoproteins, apolipoproteins, and cholesterol fractions). The study involved 24 patients with type 2 diabetes at two participating hospitals for a period of 24 weeks. Patients were randomly assigned to the anagliptin (n = 12) or control (n = 12) groups. Patients in the anagliptin group were treated with 200 mg of the drug twice daily. Patients in the control group did not receive anagliptin, but continued with their previous treatment schedules. Lipid metabolism was examined under fasting conditions at baseline and 24 weeks. Patients treated with anagliptin for 24 weeks exhibited significantly reduced levels of serum apolipoprotein B-48, a marker for lipid transport from the intestine, compared with the control group patients (P < 0.05). After 24 weeks of treatment, serum adiponectin levels were significantly raised, whereas glycated hemoglobin (HbA1c) levels were significantly lower compared with the baseline in the anagliptin group (P < 0.05), but not in the control group. This study showed that the DPP-4 inhibitor anagliptin reduces fasting apolipoprotein B-48 levels, suggesting that this drug may have beneficial effects on lipid metabolism possibly mediated by the inhibition of intestinal lipid transport.

CPT: pharmacometrics & systems pharmacology. 2020;(8):466-475
Abstract
Elagolix is an oral gonadotropin-releasing hormone antagonist approved by the US Food and Drug Administration (FDA) for the management of moderate-to-severe pain associated with endometriosis and in combination with estradiol/norethindrone acetate approved for the management of heavy menstrual bleeding associated with uterine leiomyomas (fibroids) in premenopausal women. The objective of this work was to characterize the relationships between elagolix exposures and clinical efficacy response rates for dysmenorrhea (DYS) and nonmenstrual pelvic pain (NMPP) in premenopausal women enrolled in the pivotal phase III studies with moderate-to-severe pain associated with endometriosis. Relationships between elagolix average concentrations (Cavg ) and efficacy responses (DYS and NMPP) were characterized using a nonlinear mixed-effects discrete-time first order Markov modeling approach. Only age was statistically significant for NMPP but not considered clinically relevant. This work indicates that the selection of elagolix dose is not determined based on tested patient demographics, baseline, or endometriosis disease severity measures in covariate analysis. In other words, the work suggests no preference of one regimen over the other to treat endometriosis-associated pain (DYS or NMPP) for any patient subpopulation based on tested covariate groups.

Abstract
Background: Thyroid cancer is the most common endocrine tumor with an increasing incidence. Limited treatment options are available for patients with advanced or recurrent metastatic disease, resulting in a poor prognosis. Surufatinib targets multiple kinases (vascular endothelial growth factor receptors, fibroblast growth factor receptor-1, and colony-stimulating factor-1 receptor) involved in tumor angiogenesis and tumor immune evasion. Surufatinib has demonstrated promising antitumor activity in various advanced solid tumors. This study aimed to determine the objective response rate (ORR) of surufatinib in patients with locally advanced or distant metastatic differentiated thyroid cancer (DTC) or medullary thyroid cancer (MTC). Methods: This Phase II open-label study by Simon's two-stage design was conducted at 10 sites across China. Patients with radioiodine (RAI)-refractory DTC with locally advanced disease or distant metastasis (DTC1 group); patients who received limited initial surgery and then developed locally advanced unresectable recurrences and were not considered candidates for RAI therapy due to residual normal thyroid tissue (DTC2 group); or patients with MTC with locally advanced disease or distant metastasis (MTC group) were enrolled. A total of 59 patients were enrolled (26 in DTC1, 6 in DTC2, and 27 in MTC) and received 300 mg surufatinib daily in 28-day cycles. The primary endpoint was ORR as determined by the investigators. Results: Overall ORR was 23.2% [95% confidence interval, CI 12.98-36.42]: 21.7% in the DTC1 cohort, 33.3% in the DTC2 cohort, and 22.2% in the MTC cohort. Forty-nine patients achieved disease control (87.5% [CI 75.93-94.82]): 87.0% in the DTC1 cohort, 83.3% in the DTC2 cohort, and 88.9% in the MTC cohort. Median time to response was 59.0 days, and 59.0, 85.5, and 59.0 days in the DTC1, DTC2, and MTC cohorts. Overall median progression-free survival was 11.1 months [CI 5.98-16.69]; 11.1 months in DTC1 and MTC cohorts, while the DTC2 cohort had not reached the median at the data cutoff. The most common treatment-emergent adverse events grade ≥3 were hypertension (20.3%), proteinuria (11.9%), and then elevated blood pressure, hypertriglyceridemia, and pulmonary inflammation (5.1% each). Conclusions: Surufatinib demonstrated promising efficacy with a tolerable and manageable safety profile for patients with locally advanced or metastatic MTC, RAI-refractory DTC, or locally advanced unresectable recurrences unable to receive RAI.

Abstract
BACKGROUND Endometriosis-related pain symptoms have a negative impact on health-related quality of life and productivity. In fact, as endometriosis-related symptom severity and the number of symptoms experienced increases, health-related quality of life decreases. Dysmenorrhea and nonmenstrual pelvic pain are prominent symptoms experienced by women with endometriosis and were shown to have improved with the oral, nonpeptide gonadotropin-releasing hormone antagonist, elagolix. OBJECTIVE The objective of this post hoc analysis was to address the question of if patients show a clinical response (in dysmenorrhea or nonmenstrual pelvic pain), do they also have improvements in health-related quality of life and in productivity? STUDY DESIGN This post hoc analysis used data from the Elaris Endometriosis-I and Elaris Endometriosis-II phase III, randomized, placebo-controlled studies. A surgical diagnosis of endometriosis (in the past 10 years), premenopausal, aged 18-49 years, and moderate to severe endometriosis-associated pain were among the inclusion criteria for both trials. Women self-reported pain daily using a scale ranging from 0 (no pain) to 3 (severe pain); daily pain was assigned to either dysmenorrhea or nonmenstrual pelvic pain based on self-reported bleeding on that particular day. In addition, their self-reported endometriosis-associated pain must have been an average of moderate or severe during the month leading to baseline for inclusion in the trial program. Patients were characterized as achieving a clinical response for dysmenorrhea or nonmenstrual pelvic pain (ie, responder or nonresponder), which was defined as women who did not have an increase in analgesic use and who met the pain reduction score threshold at month 3. Pain reduction score thresholds were defined separately for dysmenorrhea and nonmenstrual pelvic pain in the trial using receiver-operating characteristics analysis. Health-related quality of life was assessed using the Endometriosis Health Profile-30; work productivity was assessed using the Health-Related Productivity Questionnaire. RESULTS Women enrolled in Elaris Endometriosis-I (n = 871) and Elaris Endometriosis-II (n = 815) were included in this analysis. Patients with a clinical response during treatment to dysmenorrhea or nonmenstrual pelvic pain also experienced a meaningful improvement in all domains of the Endometriosis Health Profile-30 at month 3. Patients who did not show a dysmenorrhea or nonmenstrual pelvic pain clinical response at month 3 did not exhibit mean improvements in Endometriosis Health Profile-30 domain scores that indicate an Endometriosis Health Profile-30 responder. Productivity improved among dysmenorrhea clinical responders. In the Elaris Endometriosis-I study, clinical responders lost a total of 5.9 hours compared with a total of 13.0 hours for nonresponders of employment-related work at month 3 (P < .0001). Among women in the Elaris Endometriosis-II study, a total of 4.1 hours and 10.4 employment-related hours were lost at month 3 for dysmenorrhea responders vs nonresponders (P < .001). Similar results were obtained when analyzed by non-enstrual pelvic pain responder status. CONCLUSION Women with moderate to severe endometriosis-related pain, who are clinical responders based on dysmenorrhea and nonmenstrual pelvic pain, also experience significant and clinically meaningful improvement in health-related quality of life and productivity as measured by the Endometriosis Health Profile-30 and Health-Related Productivity Questionnaire, respectively.

Abstract
Evolution has yielded biopolymers that are constructed from exactly four building blocks and are able to support Darwinian evolution. Synthetic biology aims to extend this alphabet, and we recently showed that 8-letter (hachimoji) DNA can support rule-based information encoding. One source of replicative error in non-natural DNA-like systems, however, is the occurrence of alternative tautomeric forms, which pair differently. Unfortunately, little is known about how structural modifications impact free-energy differences between tautomers of the non-natural nucleobases used in the hachimoji expanded genetic alphabet. Determining experimental tautomer ratios is technically difficult, and so, strategies for improving hachimoji DNA replication efficiency will benefit from accurate computational predictions of equilibrium tautomeric ratios. We now report that high-level quantum-chemical calculations in aqueous solution by the embedded cluster reference interaction site model, benchmarked against free-energy molecular simulations for solvation thermodynamics, provide useful quantitative information on the tautomer ratios of both Watson-Crick and hachimoji nucleobases. In agreement with previous computational studies, all four Watson-Crick nucleobases adopt essentially only one tautomer in water. This is not the case, however, for non-natural nucleobases and their analogues. For example, although the enols of isoguanine and a series of related purines are not populated in water, these heterocycles possess N1-H and N3-H keto tautomers that are similar in energy, thereby adversely impacting accurate nucleobase pairing. These robust computational strategies offer a firm basis for improving experimental measurements of tautomeric ratios, which are currently limited to studying molecules that exist only as two tautomers in solution.

Jang, K, Jeon, JY, Moon, SJ, Kim, MG
Clinical therapeutics. 2020;(2):295-304
Abstract
PURPOSE Coadministration of lobeglitazone and dapagliflozin is expected to result in a blood glucose-lowering effect, followed by a gradual increase, in clinical usage; however, combining drugs could cause negative interactions. This study aimed to evaluate the effect of the coadministration of lobeglitazone and dapagliflozin on their individual pharmacokinetic properties at steady state in healthy male volunteers in the fasted state. METHODS This study consisted of 2 parts, each of which was a randomized, open-labeled, multiple-dose, 2-way crossover study in 20 healthy male volunteers in each part. Blood samples were taken periodically over a 48-h period after dosing to derive total plasma lobeglitazone and dapagliflozin pharmacokinetic properties; safety profile was evaluated throughout the study. FINDINGS When the pharmacokinetic properties of dapagliflozin were evaluated following its administration alone and in combination with lobeglitazone, point estimate and 90% CI of the geometric mean ratio of dapagliflozin AUCτ were entirely within the conventional bioequivalence range of 80%-125%. However, although it was not clinically meaningful, its Css,max was ~8% lower in subjects receiving multiple doses of dapagliflozin and lobeglitazone than that in those administered dapagliflozin alone. The pharmacokinetic properties of lobeglitazone were evaluated following its administration alone and in combination with dapagliflozin. The geometric mean ratios and 90% CIs of the lobeglitazone Css,max and AUCτ were within the conventional bioequivalence range of 80%-125%. IMPLICATIONS Coadministration of lobeglitazone and dapagliflozin had no apparent clinically relevant effects on the pharmacokinetic properties of either drug. Based on these findings, it is anticipated that lobeglitazone and dapagliflozin can be coadministered without dose adjustment. ClinicalTrials.gov identifier: NCT03616392.
