ABSTRACT
5-Fluorouracil (5-Fu) is the preferred drug in colorectal cancer treatment. Although 5-Fu treatment contributes to the increase in survival rates, long-term use of 5-Fu causes severe intestinal damage, eventually decreasing long-term survival. There is no standardtreatmentfor intestinal damage induced by 5-Fu. Our previous study found that 5-Fu-induced intestinal damage was connected to an increase in senescent cells, and antiaging drugs could relieve some adverse side effects caused by 5-Fu. Hence, it is essential to discover novel, potential antiaging therapeutic drugs for 5-Fu side effect treatment. According to the current study, Atorvastatincalcium (Ator) alleviated cellular senescence in human intestinal epithelial cells (HUVECs) and human umbilical vein endothelial cells (HIECs) caused by oxidative stress and 5-Fu. 5-Fu resulted in an increase in SA-β-Gal-positive cells, synchronously increased expression of aging-related proteins (p16), aging-related genes (p53, p21), and the senescence-associated secretory phenotype (SASP: IL-1β, IL-6, TNF-α), while Atorvastatincalcium (Ator) reversed the increase in these indicators. In the BALB/c mouse model, we confirmed that intestinal damage caused by 5-Fu is related to the increase in senescent cells and drug-induced inflammation, with the therapeutic effects of Ator. In addition, Ator increased the sensitivity of 5-Fu to chemotherapy in vitro and in vivo. Combination therapy significantly reduced HCT116 cell viability. Furthermore, Ator and 5-Fu present a cooperative effect on preventing the growth of tumors in CRC xenograft nude mice. In conclusion, our study demonstrates the value of Ator for treating intestinal damage. Moreover, Ator combined with 5-Fu increased the antitumor ability in CRC cells. Additionally, we provide a novel therapeutic protocol for CRC.

Action Potential Morphology Accurately Predicts Proarrhythmic Risk for Drugs With Potential to Prolong Cardiac Repolarization
Circ Arrhythm Electrophysiol. 2023 Jun 19:e011574. doi: 10.1161/CIRCEP.122.011574. Online ahead of print.
ABSTRACT
BACKGROUND: Drug-induced or acquired long QT syndrome occurs as a result of the unintended disruption of cardiac repolarization due to drugs that block cardiac ion channels. These side effects have been responsible for the withdrawal of a range of drugs from market and are a common reason for termination of the development of new drugs in the preclinical stage. Existing approaches to risk prediction are expensive and overly sensitive meaning that recently there have been renewed efforts, largely driven by the comprehensive proarrhythmic assay initiative, to develop more accurate methods for allocation of proarrhythmic risk.
METHODS: In this study, we aimed to quantify changes in the morphology of the repolarization phase of the cardiac action potential as an indicator of proarrhythmia, supposing that these shape changes might precede the emergence of ectopic depolarizations that trigger arrhythmia. To do this, we describe a new method of quantifying action potential morphology by measuring the radius of curvature of the repolarization phase both in simulated action potentials, as well as in action potentials measured from induced pluripotent stem cell-derived cardiomyocytes. Features derived from the curvature signal were used as inputs for logistic regressions to predict proarrhythmic risk.
RESULTS: Optimal risk classifiers based on morphology were able to correctly classify risk to drugs in the comprehensive proarrhythmic assay initiative panels with very high accuracy (0.9375) and outperformed conventional metrics based on action potential duration at 90% repolarization, triangulation, and charge movement (qNet).
CONCLUSIONS: Analysis of action potential morphology in response to proarrhythmic drugs improves prediction of torsadogenic risk. Furthermore, morphology metrics can be measured directly from the action potential, potentially eliminating the burden of undertaking complex screens of potency and drug-binding kinetics against multiple cardiac ion channels. As such, this method has the potential to improve and streamline regulatory assessment of proarrhythmia in preclinical drug development.

Drug-induced neutrophilic lobular panniculitis secondary to BRAF and MEK inhibitor used for treatment of low-grade glioma and its management
Proc (Bayl Univ Med Cent). 2023 May 11;36(4):521-523. doi: 10.1080/08998280.2023.2205811. eCollection 2023.
ABSTRACT
An 8-year-old boy presented with his mother for evaluation of an erythematous rash 3 weeks after the start of dual BRAF-MEK inhibition with dabrafenib and trametinib for treatment of progression of low-grade glioma. Panniculitis has been reported as a rare adverse cutaneous event induced by BRAF inhibitors, MEK inhibitors, and the combined dual BRAF-MEK therapy. Based on the patient's history, clinical presentation, and histopathological findings, a diagnosis of drug-induced neutrophilic panniculitis was made. This case describes neutrophilic panniculitis as a potential cutaneous manifestation of dual BRAF-MEK inhibitor therapy and describes the management of such side effects. Neutrophilic panniculitis is a relatively rare manifestation, characterized by neutrophilic inflammation in the subcutaneous tissue. Additionally, this case serves as a reminder to consider the cutaneous side effects of such therapies, given that MEK and BRAF inhibitors are increasingly used to treat primary brain tumors in the pediatric population. Routine inspection and early management may improve patients' quality of life and enable continuation of anticancer therapy.

Assessing adverse drug reaction reports for antidiabetic medications approved by the food and drug administration between 2012 and 2017: a pharmacovigilance study
Ther Adv Drug Saf. 2023 Jun 12;14:20420986231181334. doi: 10.1177/20420986231181334. eCollection 2023.
ABSTRACT
OBJECTIVE: Between 2012 and 2017, the U.S. Food and Drug Administration (FDA) approved 10 antidiabetic indicated therapies. Due to the limited literature on voluntarily reported safety outcomes for recently approved antidiabetic drugs, this study investigated adverse drug reactions (ADRs) reported in the FDA Adverse Event Reporting System (FAERS).
RESEARCH DESIGN AND METHODS: A disproportionality analysis of spontaneously reported ADRs was conducted. FAERS reports from January 1, 2012 to March 31, 2022 were compiled, allowing a 5-year buffer following drug approval in 2017. Reporting odds ratios were calculated for the top 10 ADRs, comparing new diabetic agents to the other approved drugs in their therapeutic class.
RESULTS: 127,525 reports were identified for newly approved antidiabetic medications listed as the primary suspect (PS). For sodium-glucose co-transporter-2 (SGLT-2) inhibitors, the odds of blood glucose increased, nausea, and dizziness being reported was greater for empagliflozin. Dapagliflozin was associated with greater reports of weight decreased. Canagliflozin was found to have a disproportionally higher number of reports for diabetic ketoacidosis, toe amputation, acute kidney injury, fungal infections, and osteomyelitis. Assessing glucagon-like peptide-1 (GLP-1) receptor agonists, dulaglutide and semaglutide were associated with greater reports of gastrointestinal adverse drug reactions. Exenatide was disproportionally associated with injection site reactions and pancreatic carcinoma reports.
CONCLUSION: Pharmacovigilance studies utilizing a large publicly available dataset allow an essential opportunity to evaluate the safety profile of antidiabetic drugs utilized in clinical practice. Additional research is needed to evaluate these reported safety concerns for recently approved antidiabetic medications to determine causality.

Prediction of Adverse Effects of Drug-Drug Interactions on Cardiovascular System Based on the Analysis of Structure-Activity Relationships
Biochemistry (Mosc). 2023 May;88(5):630-639. doi: 10.1134/S0006297923050061.
ABSTRACT
Co-administration of drugs often leads to drug-drug interactions, which could be accompanied by various adverse drug reactions that pose a threat to life and health of the patient. The effect caused by adverse drug reactions on cardiovascular system is one of the most significant manifestations of drug-drug interaction. Clinical assessment of adverse drug reactions resulting from drug-drug interaction between all drug pairs used in therapeutic practice is not possible. The purpose of this work was to build models using structure-activity analysis to predict adverse effects of drugs on cardiovascular system, mediated by pairwise interactions between the drug pairs when they are taken together. Data on the adverse effects resulting from drug-drug interaction were obtained from the DrugBank database. The data on drug pairs that do not cause such effects, which are necessary for building accurate structure-activity models, were obtained from the TwoSides database, which contains the results of analysis of the spontaneous reports. Two types of descriptors were used to describe a pair of drug structures: PoSMNA descriptors and probabilistic estimates of the prediction of biological activities obtained using the PASS program. Structure-activity relationships were established using the Random Forest method. Prediction accuracy was calculated by means of five-fold cross-validation. The highest accuracy values were obtained using PASS probabilistic estimates as descriptors. The area under the ROC curve was 0.94 for bradycardia, 0.96 for tachycardia, 0.90 for arrhythmia, 0.90 for ECG QT prolongation, 0.91 for hypertension, 0.89 for hypotension.

A data-driven approach for predicting the impact of drugs on the human microbiome
Nat Commun. 2023 Jun 17;14(1):3614. doi: 10.1038/s41467-023-39264-0.
ABSTRACT
Many medications can negatively impact the bacteria residing in our gut, depleting beneficial species, and causing adverse effects. To guide personalized pharmaceutical treatment, a comprehensive understanding of the impact of various drugs on the gut microbiome is needed, yet, to date, experimentally challenging to obtain. Towards this end, we develop a data-driven approach, integrating information about the chemical properties of each drug and the genomic content of each microbe, to systematically predict drug-microbiome interactions. We show that this framework successfully predicts outcomes of in-vitro pairwise drug-microbe experiments, as well as drug-induced microbiome dysbiosis in both animal models and clinical trials. Applying this methodology, we systematically map a large array of interactions between pharmaceuticals and human gut bacteria and demonstrate that medications' anti-microbial properties are tightly linked to their adverse effects. This computational framework has the potential to unlock the development of personalized medicine and microbiome-based therapeutic approaches, improving outcomes and minimizing side effects.

Trastuzumab deruxtecan in patients in the USA and Europe with HER2-positive advanced gastric or gastroesophageal junction cancer with disease progression on or after a trastuzumab-containing regimen (DESTINY-Gastric02): primary and updated analyses...
Lancet Oncol. 2023 Jun 14:S1470-2045(23)00215-2. doi: 10.1016/S1470-2045(23)00215-2. Online ahead of print.
ABSTRACT
BACKGROUND: Approximately 15-20% of advanced gastric and gastro-oesophageal junction cancers overexpress HER2. In DESTINY-Gastric01, the HER2-targeted antibody-drug conjugate trastuzumab deruxtecan improved response and overall survival versus chemotherapy in patients from Japan and South Korea with locally advanced or metastatic HER2-positive gastric or gastro-oesophageal junction cancer whose disease progressed after two lines of previous therapy including trastuzumab. Here, we report primary and updated analyses of the single-arm, phase 2 DESTINY-Gastric02 trial, which aimed to examine trastuzumab deruxtecan in patients living in the USA and Europe.
METHODS: DESTINY-Gastric02 is a single-arm, phase 2 study in adult patients from 24 study sites in the USA and Europe (Belgium, Spain, Italy, and the UK). Eligible patients were aged at least 18 years and had an Eastern Cooperative Oncology Group performance status of 0 or 1, pathologically documented unresectable or metastatic gastric or gastro-oesophageal junction cancer, progressive disease on or after first-line therapy with a trastuzumab-containing regimen, with at least one measurable lesion per Response Evaluation Criteria in Solid Tumours (version 1.1), and centrally confirmed HER2-positive disease on a postprogression biopsy. Patients were given 6·4 mg/kg of trastuzumab deruxtecan intravenously every 3 weeks until disease progression, withdrawal by patient, physician decision, or death. The primary endpoint was confirmed objective response rate by independent central review. The primary endpoint and safety were assessed in the full analysis set (ie, participants who received at least one dose of study drug). Here, we report the primary analysis of this study, with a data cutoff of April 9, 2021, and an updated analysis, with a data cutoff of Nov 8, 2021. This trial is registered with ClinicalTrials.gov, NCT04014075, and is ongoing.
FINDINGS: Between Nov 26, 2019, and Dec 2, 2020, 89 patients were screened and 79 were enrolled and subsequently treated with trastuzumab deruxtecan (median age 60·7 years [IQR 52·0-68·3], 57 [72%] of 79 were male, 22 [28%] were female, 69 [87%] were White, four [5%] were Asian, one [1%] was Black or African American, one [1%] was Native Hawaiian or Pacific Islander, one had missing race, and three [4%] were other races). At the primary analysis (median follow-up 5·9 months [IQR 4·6-8·6 months]), confirmed objective response was reported in 30 (38% [95% CI 27·3-49·6]) of 79 patients, including three (4%) complete responses and 27 (34%) partial responses, as assessed by independent central review. As of data cutoff for the updated analysis (median follow-up 10·2 months [IQR 5·6-12·9]), a confirmed objective response was reported in 33 (42% [95% CI 30·8-53·4]) of 79 patients, including four (5%) complete responses and 29 (37%) partial responses, as assessed by independent central review. The most common grade 3 or worse treatment-emergent adverse events were anaemia (11 [14%]), nausea (six [8%]), decreased neutrophil count (six [8%]), and decreased white blood cell count (five [6%]). Drug-related serious treatment-emergent adverse events occurred in ten patients (13%). Deaths determined to be associated with study treatment occurred in two patients (3%) and were due to interstitial lung disease or pneumonitis.
INTERPRETATION: These clinically meaningful results support the use of trastuzumab deruxtecan as second-line therapy in patients with HER2-positive advanced gastric or gastro-oesophageal junction cancer.

Netarsudil monotherapy as the initial treatment for open-angle glaucoma and ocular hypertension in Indian patients: A real-world evaluation of efficacy and safety
Indian J Ophthalmol. 2023 Jun;71(6):2500-2503. doi: 10.4103/IJO.IJO_25_23.
ABSTRACT
PURPOSE: Glaucoma is the second leading cause of blindness worldwide, affecting more than 64 million people aged 40-80. The best way to manage primary open-angle glaucoma (POAG) is by lowering the intraocular pressure (IOP). Netarsudil is a Rho kinase inhibitor, the only class of antiglaucoma medications that reorganizes the extracellular matrix to improve the aqueous outflow through the trabecular pathway.
METHODS: An open-label, real-world, multicentric, observation-based 3-month study was performed for assessing the safety and ocular hypotensive efficacy of netarsudil ophthalmic solution (0.02% w/v) in patients with elevated IOP. Patients were given netarsudil ophthalmic solution (0.02% w/v) as a first-line therapy. Diurnal IOP measurements, best-corrected visual acuity, and adverse event assessments were recorded at each of the five visits (Day-1: screening day and first dosing day; subsequent observations were taken at 2 weeks, 4 weeks, 6 weeks, and 3 months).
RESULTS: Four hundred and sixty-nine patients from 39 centers throughout India completed the study. The mean IOP at baseline of the affected eyes was 24.84 ± 6.39 mmHg (mean ± standard deviation). After the first dose, the IOP was measured after 2, 4, and 6 weeks, with the final measurement taken at 3 months. The percentage reduction in IOP in glaucoma patients after 3 months of once-daily netarsudil 0.02% w/v solution use was 33.34%. The adverse effects experienced by patients were not severe in the majority of cases. Some adverse effects observed were redness, irritation, itching, and others, but only a small number of patients experienced severe reactions, as reported in a decreasing order: redness > irritation > watering > itching > stinging > blurring.
CONCLUSION: We found that netarsudil 0.02% w/v solution monotherapy when used as the first-line treatment in primary open-angle glaucoma and ocular hypertension was both safe and effective.

First-in-Human, Phase I Dose-Escalation and Dose-Expansion Study of Trophoblast Cell-Surface Antigen 2-Directed Antibody-Drug Conjugate Datopotamab Deruxtecan in Non-Small-Cell Lung Cancer: TROPION-PanTumor01
J Clin Oncol. 2023 Jun 16:JCO2300059. doi: 10.1200/JCO.23.00059. Online ahead of print.
ABSTRACT
PURPOSE: This first-in-human, dose-escalation and dose-expansion study evaluated the safety, tolerability, and antitumor activity of datopotamab deruxtecan (Dato-DXd), a novel trophoblast cell-surface antigen 2 (TROP2)-directed antibody-drug conjugate in solid tumors, including advanced non-small-cell lung cancer (NSCLC).
PATIENTS AND METHODS: Adults with locally advanced/metastatic NSCLC received 0.27-10 mg/kg Dato-DXd once every 3 weeks during escalation or 4, 6, or 8 mg/kg Dato-DXd once every 3 weeks during expansion. Primary end points were safety and tolerability. Secondary end points included objective response rate (ORR), survival, and pharmacokinetics.
RESULTS: Two hundred ten patients received Dato-DXd, including 180 in the 4-8 mg/kg dose-expansion cohorts. This population had a median of three prior lines of therapy. The maximum tolerated dose was 8 mg/kg once every 3 weeks; the recommended dose for further development was 6 mg/kg once every 3 weeks. In patients receiving 6 mg/kg (n = 50), median duration on study, including follow-up, and median exposure were 13.3 and 3.5 months, respectively. The most frequent any-grade treatment-emergent adverse events (TEAEs) were nausea (64%), stomatitis (60%), and alopecia (42%). Grade ≥3 TEAEs and treatment-related AEs occurred in 54% and 26% of patients, respectively. Interstitial lung disease adjudicated as drug-related (two grade 2 and one grade 4) occurred in three of 50 patients (6%). The ORR was 26% (95% CI, 14.6 to 40.3), and median duration of response was 10.5 months; median progression-free survival and overall survival were 6.9 months (95% CI, 2.7 to 8.8 months) and 11.4 months (95% CI, 7.1 to 20.6 months), respectively. Responses occurred regardless of TROP2 expression.
CONCLUSION: Promising antitumor activity and a manageable safety profile were seen with Dato-DXd in heavily pretreated patients with advanced NSCLC. Further investigation as first-line combination therapy in advanced NSCLC and as monotherapy in the second-line setting and beyond is ongoing.

Prevention and treatment of antipsychotic induced weight gain
Tijdschr Psychiatr. 2023;65(4):259-265.
ABSTRACT
BACKGROUND: Metformin is the most investigated pharmacological treatment of antipsychotics-induced weight gain (AIWG). Based on a systematic literature review, the first guideline for the treatment of AIWG with metformin was recently published.
AIM: To present a step-by-step plan, based on recent literature and clinical experience to monitor, prevent, and treat AIWG.
METHOD: Literature search to give specific advice on the choice of antipsychotic medication, stop, dose reduction or switch of antipsychotic, screening, non-pharmacological and pharmacological interventions to prevent and treat AIWG.
RESULTS: Especially in the first year of antipsychotic treatment timely detection of AIWG through regular monitoring is pivotal. The best way to treat AIWG is to prevent its emergence by choosing an antipsychotic with a favourable metabolic profile. Secondly, by titration of antipsychotic medication to the lowest dose possible. Achieving a healthy lifestyle shows a limited beneficial effect on AIWG. Drug-induced weight loss can be attained by the addition of metformin, topiramate, or aripiprazole. Topiramate and aripiprazole can improve positive and negative residual symptoms of schizophrenia. The evidence on liraglutide is scarce. All augmentation strategies may cause side effects. Besides, in case of nonresponse augmentation therapy should be stopped to prevent unnecessary polypharmacy.
CONCLUSION: In the revision of the Dutch multidisciplinary guideline for schizophrenia, the detection, prevention, and treatment of AIWG deserves more attention.

The anxiolytic effects of preoperative administration of pregabalin in comparison to diazepam and placebo
Sci Rep. 2023 Jun 15;13(1):9680. doi: 10.1038/s41598-023-36616-0.
ABSTRACT
We aimed to evaluate the potential anxiolytic effects of premedication with pregabalin, compared with diazepam and placebo. We conducted this non-inferiority, double-blind, randomized controlled trial in ASA classification I-II patients aged 18-70 years, scheduled for elective surgery under general anesthesia. They were allocated to receive pregabalin (75 mg the night before surgery and 150 mg 2 h before surgery), diazepam (5 and 10 mg in the same manner) or placebo. Preoperative anxiety was evaluated using verbal numerical rating scale (VNRS) and Amsterdam Preoperative Anxiety and Information Scale (APAIS) before and after premedication. Sleep quality, sedation level, and adverse effects were assessed as secondary outcomes. A total of 231 patients were screened and 224 completed the trial. The mean change (95%CI) in anxiety scores from before to after medication in pregabalin, diazepam, and placebo groups for VNRS were - 0.87 (- 1.43, - 0.30), - 1.17 (- 1.74, - 0.60), and - 0.99 (- 1.56, - 0.41), and for APAIS were - 0.38 (- 1.04, 0.28), - 0.83 (- 1.49, - 0.16), and - 0.27 (- 0.95, 0.40). The difference in change for pregabalin versus diazepam was 0.30 (- 0.50, 1.11) for VNRS and 0.45 (- 0.49, 1.38) for APAIS, exceeding the limit of inferiority for APAIS of 1.3. Sleep quality was statistically different between pregabalin and placebo groups (p = 0.048). Sedation in pregabalin and diazepam groups were significantly higher than placebo group (p = 0.008). No significant differences of other side effects, except dry mouth was higher in placebo group compared with diazepam (p = 0.006). The study filed to provide evidence at non-inferiority of pregabalin compared to diazepam. Furthermore, premedication with either pregabalin or diazepam did not significantly reduce the preoperative anxiety in comparison to placebo, despite the fact that both resulted in higher levels of sedation. Clinicians should weigh the benefits and risks of premedication with these 2 drugs.Thai Clinical Trials Registry: TCTR20190424001 (24/04/2019) Registry URL: https://www.thaiclinicaltrials.org/ .

Is magnetic sphincter augmentation indicated in patients with laryngopharyngeal reflux?
Dis Esophagus. 2023 Jun 15;36(Supplement_1):doad012. doi: 10.1093/dote/doad012.
ABSTRACT
Up to 30% of patients with gastroesophageal reflux disease (GERD) suffer from laryngopharyngeal reflux (LPR) with symptoms, as chronic cough, laryngitis, or asthma. Besides life-style modifications and medical acid suppression, laparoscopic fundoplication is an established treatment option. Treatment-related side effects after laparoscopic fundoplication have to be weighted against LPR symptom control in 30-85% of patients after surgery. Magnetic sphincter augmentation (MSA) is described as an effective alternative to fundoplication for surgical treatment of GERD. However, evidence on the efficacy of MSA in patients with LPR is very limited. Preliminary data on the results of MSA treating LPR symptoms in patients with acid and weakly acid reflux are promising; showing comparable results to laparoscopic fundoplication by providing the potential of decrease side effects.

Two-year, real-world erenumab persistence and quality of life data in 82 pooled patients with abrupt onset, unremitting, treatment refractory headache and a migraine phenotype: New daily persistent headache or persistent post-traumatic headache in the...
Cephalalgia. 2023 Jun;43(6):3331024231182126. doi: 10.1177/03331024231182126.
ABSTRACT
BACKGROUND: Patients diagnosed with New Daily Persistent Headache and Persistent Post-Traumatic Headache belong to a heterogeneous group of primary and secondary headache disorders, with the common clinical feature that these conditions start abruptly, continue unabated, and are refractory to conventional migraine preventive treatments.
OBJECTIVE: This is a real-world, medium-term audit to explore whether erenumab improves quality of life in a pooled group of 82 abrupt-onset, unremitting and treatment refractory patients, where the diagnosis is new daily persistent headache and persistent post-traumatic headache in the majority of cases.
METHODS: Eighty-two patients were treated with erenumab every 28 days over a two to three-year period, beginning in December 2018. These patients were "longstanding chronic" and refractory with a median of eight (IQR 4-12) prior failed migraine preventive treatments and median duration of disease of seven (IQR 3-11) years. The starting dose of erenumab was 70 mg in 79% of cases and 140 mg in the remaining patients (individuals with a BMI of more than 30). All patients were asked to complete three migraine specific Quality of Life questionnaires or Patient Reported Outcome Measures before starting treatment and typically at 3-12 intervals until the end of June 2021 or cessation of treatment. The Patient Reported Outcome Measures included: Headache Impact Test-6, Migraine Associated Disability Assessment test and Migraine-Specific Quality-of-Life Questionnaire. Patients generally only stayed on treatment after 6-12 months if there was deemed to be an improvement of at least 30% and there were no significant side effects. The longest treated cases have quality of life data for 30 months after starting erenumab.
RESULTS: Of the 82 patients, 29 (35%) had improvement in Quality of Life scores, with no significant side effects, and wished to stay on treatment. Fifty-three patients (65%) stopped treatment during the first 6-25 months due to lack of efficacy and/or patient reported side effects (n = 33 and n = 17, respectively) or a combination of both, pregnancy planning (n = 2), and lost to follow up (n = 1).
CONCLUSION: Significant improvements in Quality of Life scores were recorded by one-third of patients over a period of 11-30 months, with a 35% persistence after a median of 26 months of treatment. This contrasts with our recently published, treatment resistant, chronic migraine cohort where the persistence with erenumab treatment was almost 55% after a median time of 25 months.

Physiologic Changes During Pregnancy and Impact on Small-Molecule Drugs, Biologic (Monoclonal Antibody) Disposition, and Response
J Clin Pharmacol. 2023 Jun;63 Suppl 1:S34-S50. doi: 10.1002/jcph.2227.
ABSTRACT
Pregnancy is a unique physiological state that results in many changes in bodily function, including cellular, metabolic, and hormonal changes. These changes can have a significant impact on the way small-molecule drugs and monoclonal antibodies (biologics) function and are metabolized, including efficacy, safety, potency, and adverse effects. In this article, we review the various physiologic changes that occur during pregnancy and their effects on drug and biologic metabolism, including changes in the coagulation, gastrointestinal, renal, endocrine, hepatic, respiratory, and cardiovascular systems. Additionally, we discuss how these changes can affect the processes of drug and biologic absorption, distribution, metabolism, and elimination (pharmacokinetics), and how drugs and biologics interact with biological systems, including mechanisms of drug action and effect (pharmacodynamics) during pregnancy, as well as the potential for drug-induced toxicity and adverse effects in the mother and developing fetus. The article also examines the implications of these changes for the use of drugs and biologics during pregnancy, including consequences of suboptimal plasma drug concentrations, effect of pregnancy on the pharmacokinetics and pharmacodynamics of biologics, and the need for careful monitoring and individualized drug dosing. Overall, this article aims to provide a comprehensive understanding of the physiologic changes during pregnancy and their effects on drug and biologic metabolism to improve the safe and effective use of drugs.

Cardiomuscular Biomarkers in the Diagnosis and Prognostication of Immune Checkpoint Inhibitor Myocarditis
Circulation. 2023 Jun 15. doi: 10.1161/CIRCULATIONAHA.123.062405. Online ahead of print.
ABSTRACT
BACKGROUND: Immune checkpoint inhibitors (ICIs) are approved for multiple cancers but can result in ICI-associated myocarditis, an infrequent but life-threatening condition. Elevations in cardiac biomarkers, specifically troponin-I (cTnI), troponin-T (cTnT), and creatine kinase (CK), are used for diagnosis. However, the association between temporal elevations of these biomarkers with disease trajectory and outcomes has not been established.
METHODS: We analyzed the diagnostic accuracy and prognostic performances of cTnI, cTnT, and CK in patients with ICI myocarditis (n=60) through 1-year follow-up in 2 cardio-oncology units (APHP Sorbonne: Paris, France and Heidelberg, Germany). A total of 1751 (1 cTnT assay type), 920 (4 cTnI assay types), and 1191 CK sampling time points were available. Major adverse cardiomyotoxic events (MACE) were defined as heart failure, ventricular arrhythmia, atrioventricular or sinus block requiring pacemaker, respiratory muscle failure requiring mechanical ventilation, and sudden cardiac death. Diagnostic performance of cTnI and cTnT was also assessed in an international ICI myocarditis registry.
RESULTS: Within 72 hours of admission, cTnT, cTnI, and CK were increased compared with upper reference limits (URLs) in 56 of 57 (98%), 37 of 42 ([88%] P=0.03 versus cTnT), and 43 of 57 ([75%] P<0.001 versus cTnT), respectively. This increased rate of positivity for cTnT (93%) versus cTnI ([64%] P<0.001) on admission was confirmed in 87 independent cases from an international registry comprising 13 countries. In the Franco-German cohort, 24 of 60 (40%) patients developed ≥1 MACE (total, 52; median time to first MACE, 5 [interquartile range, 2-16] days). The highest value of cTnT:URL within the first 72 hours of admission performed best in terms of association with MACE within 90 days (area under the curve, 0.84) than CK:URL (area under the curve, 0.70). A cTnT:URL ≥32 within 72 hours of admission was the best cut-off associated with MACE within 90 days (hazard ratio, 11.1 [95% CI, 3.2-38.0]; P<0.001), after adjustment for age and sex. cTnT was increased in all patients within 72 hours of the first MACE (23 of 23 [100%]), whereas cTnI and CK values were less than the URL in 2 of 19 (11%) and 6 of 22 (27%) of patients (P<0.001), respectively.
CONCLUSIONS: cTnT is associated with MACE and is sensitive for diagnosis and surveillance in patients with ICI myocarditis. A cTnT:URL ratio <32 within 72 hours of diagnosis is associated with a subgroup at low risk for MACE. Potential differences in diagnostic and prognostic performances between cTnT and cTnI as a function of the assays used deserve further evaluation in ICI myocarditis.

Use of Bevacizumab in recurrent glioblastoma: a scoping review and evidence map
BMC Cancer. 2023 Jun 14;23(1):544. doi: 10.1186/s12885-023-11043-6.
ABSTRACT
BACKGROUND: Glioblastoma (GBM) is the most malignant primary tumor in the brain, with poor prognosis and limited effective therapies. Although Bevacizumab (BEV) has shown promise in extending progression-free survival (PFS) treating GBM, there is no evidence for its ability to prolong overall survival (OS). Given the uncertainty surrounding BEV treatment strategies, we aimed to provide an evidence map associated with BEV therapy for recurrent GBM (rGBM).
METHODS: PubMed, Embase, and the Cochrane Library were searched for the period from January 1, 1970, to March 1, 2022, for studies reporting the prognoses of patients with rGBM receiving BEV. The primary endpoints were overall survival (OS) and quality of life (QoL). The secondary endpoints were PFS, steroid use reduction, and risk of adverse effects. A scoping review and an evidence map were conducted to explore the optimal BEV treatment (including combination regimen, dosage, and window of opportunity).
RESULTS: Patients with rGBM could gain benefits in PFS, palliative, and cognitive advantages from BEV treatment, although the OS benefits could not be verified with high-quality evidence. Furthermore, BEV combined therapy (especially with lomustine and radiotherapy) showed higher efficacy than BEV monotherapy in the survival of patients with rGBM. Specific molecular alterations (IDH mutation status) and clinical features (large tumor burden and double-positive sign) could predict better responses to BEV administration. A low dosage of BEV showed equal efficacy to the recommended dose, but the optimal opportunity window for BEV administration remains unclear.
CONCLUSIONS: Although OS benefits from BEV-containing regimens could not be verified in this scoping review, the PFS benefits and side effects control supported BEV application in rGBM. Combining BEV with novel treatments like tumor-treating field (TTF) and administration at first recurrence may optimize the therapeutic efficacy. rGBM with a low apparent diffusion coefficient (ADCL), large tumor burden, or IDH mutation is more likely to benefit from BEV treatment. High-quality studies are warranted to explore the combination modality and identify BEV-response subpopulations to maximize benefits.

Neurological aspects of diagnosis and treatment of motor alalia
Zh Nevrol Psikhiatr Im S S Korsakova. 2023;123(5):74-82. doi: 10.17116/jnevro202312305174.
ABSTRACT
OBJECTIVE: To analyze the causes of violations of expressive speech in children 4-5 years old, to assess changes in neurological status in children with motor alalia without and during treatment with Cellex.
MATERIAL AND METHODS: Two groups of patients were recruited: the main group (n=30; treatment; Cellex) and the control group (n=12; without Cellex). The drug was administered in the first half of the day by 1.0 ml subcutaneously, 10 days, daily. The patient's visit card was analyzed 4 times: before treatment, 10 days later, 1 and 2 months after the start of treatment. Statistical hypotheses were tested using the χ2 and Fisher criterions, the odds ratio (OR) and the 95% confidence interval (CI) OR were determined.
RESULTS: In more than half of the cases, violations of the neurological status, the burden of the perinatal period, a decrease in cognitive tests, and a lack of fine motor skills were revealed. Left-handedness or two-handedness, overload of viewing or listening to gadgets from the age of up to a year, violations of opercular praxis were almost always noted. The effect of the drug Cellex on the «launch of speech» in children with motor alalia has been shown. It has been established that the drug is well tolerated, has no adverse side effects and has a positive effect on the «launch of speech». The progress of the dynamics of speech development, progress in play and cognitive activity was observed in all children of the main group.
CONCLUSION: The use of the drug Cellex can be effective in the treatment of children with motor alalia.

Development of AlissAID system targeting GFP or mCherry fusion protein
PLoS Genet. 2023 Jun 14;19(6):e1010731. doi: 10.1371/journal.pgen.1010731. eCollection 2023 Jun.
ABSTRACT
Conditional control of target proteins using the auxin-inducible degron (AID) system provides a powerful tool for investigating protein function in eukaryotes. Here, we established an Affinity-linker based super-sensitive auxin-inducible degron (AlissAID) system in budding yeast by using a single domain antibody (a nanobody). In this system, target proteins fused with GFP or mCherry were degraded depending on a synthetic auxin, 5-Adamantyl-IAA (5-Ad-IAA). In AlissAID system, nanomolar concentration of 5-Ad-IAA induces target degradation, thus minimizing the side effects from chemical compounds. In addition, in AlissAID system, we observed few basal degradations which was observed in other AID systems including ssAID system. Furthermore, AlissAID based conditional knockdown cell lines are easily generated by using budding yeast GFP Clone Collection. Target protein, which has antigen recognition sites exposed in cytosol or nucleus, can be degraded by the AlissAID system. From these advantages, the AlissAID system would be an ideal protein-knockdown system in budding yeast cells.

Gaps in evidence on treatment of male osteoporosis: a Research Agenda
Aging Male. 2023 Dec;26(1):2223699. doi: 10.1080/13685538.2023.2223699.
ABSTRACT
OBJECTIVE: To identify key research gaps regarding medication therapy to prevent osteoporotic fractures in men.
DATA SOURCES: Articles from the peer-reviewed literature containing empirical studies of the use of medication therapy for fracture prevention in men, either in clinical trials or observational studies.
STUDY SELECTION AND DATA EXTRACTION: We searched PubMed with search terms including "osteoporosis AND medication therapy management". We read all articles to ensure that they were indeed empirical studies of our topic. For each included study, we searched for all articles in the bibliography, all articles that cited the article, and all related articles, using these functions in PubMed.
DATA SYNTHESIS: We have identified six research gaps that could inform the more rational, evidence-based treatment of male osteoporosis. Specifically, among men, we lack key information about: (1) whether treatment can prevent clinical fractures, (2) rates of side effects and complications of therapy, (3) the role of testosterone in treatment, (4) the comparative effectiveness of different therapeutic regimens, (5) role of drug holidays for those receiving bisphosphonates and sequential therapies, and (6) effectiveness of therapy for secondary prevention.
RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE: Addressing these six topics should be key goal for the next decade of research on male osteoporosis.
